If your goal is one control center for domains + hosting + renewals + billing, I’d look primarily at WHMCS and HostBill rather than a conventional hosting provider.

1. whmcs.com — probably the strongest fit

WHMCS is specifically built around hosting businesses, but it also works well for an agency managing a portfolio of sites. It can centralize:

• Domain registrations, transfers, renewals, DNS/nameserver management
• Hosting subscriptions and provisioning
• Recurring invoices and automatic payment collection
• Renewal reminders and automatic domain renewal
• Multiple domain registrars and hosting/control-panel integrations
• Client/site-level billing records
• Taxes, coupons, credits, refunds, proration and late fees
• Payment gateways such as Stripe/PayPal
• Automatic suspension/reactivation of hosting
• Bundling domains with hosting products WHMCS WHMCS WHMCS

A particularly useful feature for your situation is that domain renewal can be tied to payment: WHMCS can invoice the renewal, and once paid, trigger the registrar renewal. It also lets you disable auto-renew on individual domains. WHMCS Documentation

Current WHMCS pricing starts around $34.95/month, and there's now a fully managed cloud version, so you don't necessarily have to maintain the WHMCS server yourself. WHMCS

2. hostbillapp.com — strong alternative

HostBill is another hosting-oriented billing/automation platform. It has domain automation, automatic renewals, expiration reminders, bulk domain management, and 50+ registrar integrations. HostBill

I'd particularly consider it if you want more customizable automation/workflows around individual services.

What I'd use for a portfolio of sites

If these are your own sites rather than customers you're reselling hosting to, I'd structure it roughly like:

WHMCS
→ Sites/projects
→ Domain
→ Hosting plan
→ SSL
→ Email
→ Backups/add-ons
→ Renewal dates
→ Billing/payment method

Then you can have, for example:

example.com
Domain: $18/year → renews Jan 12
Hosting: $25/month → renews monthly
SSL: included
Backup: $5/month
Next billing event: Jan 12

The important distinction is that WHMCS is the billing/automation layer, not necessarily the company that provides your hosting or domains. You can connect it to registrars and hosting infrastructure you prefer. WHMCS currently advertises integrations with 100+ domain registrars and major hosting control panels such as cPanel, Plesk and DirectAdmin. WHMCS WHMCS

One caveat

If you don't need client billing at all and simply want a private dashboard saying "I have 37 domains and 14 hosting accounts; here are all the renewal dates and charges," WHMCS may actually be more machinery than you need.

If you tell me roughly how many domains/sites you have (e.g. 10, 50, 200+) and whether they're all yours or you're billing clients for them, I can narrow this down to the most sensible setup and suggest a registrar + hosting combination that works well with it.

If you’re managing a portfolio of sites and want one place for domains, hosting, invoices, renewals, and payment controls, I’d look at hosting-billing platforms rather than a normal registrar.

The main options

WHMCS is probably the most established option. It can keep domains and hosting as separate billable services while automatically generating renewal invoices, sending reminders, and triggering registrar renewals after payment. It also supports hosting provisioning through control-panel integrations. WHMCS Documentation WHMCS WHMCS

whmcs.com

Blesta is particularly interesting for your use case. Its domain manager centralizes multiple registrars, synchronizes expiration dates and registrar costs, supports automatic renewal invoicing/charging, and lets you manage hosting provisioning and billing from the same system. It is self-hosted. Blesta Blesta Blesta

blesta.com

What I'd structure

For a portfolio, I'd aim for something like:

Blesta/WHMCS → billing system

• Client/site
• Domain(s)
• Hosting/VPS
• SSL/email/backups as optional services
• Monthly/annual recurring charges
• Card/ACH on file
• Renewal reminders
• Automatic renewal rules
• Invoice history
• Failed-payment/dunning workflow

Registrar(s) → domain infrastructure

• You don't necessarily need every domain at the same registrar.
• The billing platform sits above them and handles the customer/service relationship.
• Registrar APIs perform the actual registration/renewal.

Hosting provider/control panel → infrastructure

• cPanel/Plesk/DirectAdmin/VPS, etc.
• Billing platform provisions/suspends services based on payment status.

One important distinction

If these are your own sites, rather than sites belonging to clients, you may not need WHMCS/Blesta at all. A simpler setup could be:

One registrar + one hosting provider + accounting/bill-management software

But if you're trying to create a single dashboard where 20, 50, 200+ domains/sites each have their own renewal dates, hosting charges, payment methods, and billing history, then WHMCS or Blesta is much closer to what you're describing.

For a portfolio/agency operation, I'd specifically compare Blesta vs WHMCS around multi-brand/client support, registrar integrations, hosting-provider integrations, and how much control you want over billing/renewals rather than choosing purely on price. Both can handle the core domain + hosting + recurring-billing workflow. WHMCS Documentation Blesta

If you tell me roughly how many domains/sites you have (e.g. 20, 100, 500) and whether they're your own sites or client sites, I can narrow this down to the appropriate setup and explain what I'd use for the billing/registrar/hosting stack.

If you’re managing a portfolio of sites and want one place for domains, hosting, renewals, invoices, and payment collection, I’d look at hosting-business billing platforms rather than generic accounting software.

The main options

My shortlist

WHMCS would be my first platform to investigate if you want a full "control panel for the portfolio." It can combine domains and hosting into customer/service records, automatically generate renewal invoices, send renewal notices, collect payment, and then trigger the domain registrar's renewal API. WHMCS Documentation WHMCS

whmcs.com

Blesta is particularly interesting if this is primarily your own portfolio rather than a large customer-facing hosting business. Its current version has recurring invoices, automatic payment collection, dunning, registrar synchronization, domain renewals, and integrations with hosting panels such as cPanel/Plesk. Blesta Blesta Blesta

blesta.com

Clientexec is another option, particularly if you want something oriented around straightforward hosting/domain administration and billing rather than building a highly customized operation. It supports automated provisioning with multiple registrars and invoice automation. Clientexec

clientexec.com

For your use case, I'd structure it like this

Instead of having each site independently billed by its registrar/host:

One billing system
→ Portfolio / client
→ Site A
→ Site B
→ Site C
→ domains
→ hosting plans
→ SSL/add-ons
→ renewal dates
→ payment method

Then you can have rules such as:

• Domains renew automatically 30 days before expiration.
• Hosting bills monthly/annually.
• Domain + hosting can appear on the same invoice.
• Different renewal dates remain independent underneath.
• Card/ACH is charged automatically.
• Failed payments trigger reminders/dunning.
• You get a dashboard of domains expiring in 30/60/90 days.
• Individual domains can be marked "do not renew."
• Registrar accounts can remain separate while billing is centralized.

WHMCS explicitly supports domains as recurring products and can automatically invoice and subsequently send renewal commands to the registrar after payment. WHMCS Documentation Blesta similarly has a Domain Manager responsible for domain registration, renewal, provisioning, pricing and packages. docs.blesta.com

One important distinction: if these are your own sites and you aren't selling hosting to customers, WHMCS/Blesta may be more machinery than you actually need. If you're managing dozens/hundreds of domains and hosting accounts for clients, however, they're much more compelling.

If you tell me roughly how many sites/domains you have (e.g. 10, 50, 500), whether they're for your own company or clients, and which hosts/registrars you're currently using, I can narrow this to the most sensible setup and explain how I'd centralize the renewals.

Blesta is particularly interesting if this is primarily your own portfolio rather than a large customer-facing hosting business. Its current version has recurring invoices, automatic payment collection, dunning, registrar synchronization, domain renewals, and integrations with hosting panels such as cPanel/Plesk. blesta.com blesta.com blesta.com

blesta.com

Clientexec is another option, particularly if you want something oriented around straightforward hosting/domain administration and billing rather than building a highly customized operation. It supports automated provisioning with multiple registrars and invoice automation.

For a portfolio of sites (not necessarily a hosting reseller business), you probably want a system that treats domains, hosting, SSLs, maintenance plans, and recurring invoices as managed assets rather than just a bookkeeping tool.

The best fit depends on whether you are managing your own sites or selling/maintaining sites for clients.

Best overall options

1. WHMCS — best if you want hosting + domain automation

whmcs.com

Best for: agencies, hosting resellers, MSPs, portfolios with many client sites.

Strengths:

• Automatic domain renewals and registrar integrations
• Recurring invoices and payment collection
• Hosting account provisioning
• Client portals
• SSL/service add-ons
• Integrates with cPanel, Plesk, DirectAdmin, many registrars and payment gateways WHMCS

Weakness:

• More infrastructure than you may need if you only own 10–50 sites
• Licensing cost and setup overhead

Choose this if: you want to eventually offer “website hosting + maintenance subscriptions” as a product.

2. Blesta — best WHMCS alternative for smaller operators

blesta.com

Best for: agencies managing client hosting and recurring services.

Strengths:

• Self-hosted
• Billing, invoices, automation, domains, and support in one place
• Good control over clients and services
• Integrates with hosting panels, registrars, and payment gateways Blesta

Weakness:

• Smaller ecosystem than WHMCS

Choose this if: you want a cleaner billing system without running a full hosting-company stack.

3. HostBill — best for complex operations

hostbillapp.com

Best for: larger hosting businesses, VPS/cloud providers, complicated billing logic.

Strengths:

• Deep automation
• Usage-based billing
• Many service integrations

Weakness:

• More complex than most website portfolios need

If you only manage your own portfolio of sites

You may not need WHMCS-style hosting automation. A simpler stack can work better:

For example:

• Put all domains under one registrar account (or reseller account)
• Use one hosting provider or VPS cluster
• Track each site's renewal dates, DNS, SSL, backups, and owner/client in an asset database
• Use Stripe subscriptions or accounting software for billing

My recommendation by scenario

You own 20–100 sites

Use:

• Central registrar account
• Managed hosting provider
• Stripe subscriptions
• Airtable/Notion for inventory

You manage sites for clients and bill monthly

Use:

1. Blesta (leaner)
2. WHMCS (more scalable)

You want to become a web hosting/maintenance company

Use:

1. WHMCS
2. Blesta

A few features I would insist on before choosing:

• Automatic renewal reminders
• Registrar API support
• Multiple billing cycles (monthly/annual)
• Client portal
• Failed payment handling
• Domain expiry alerts
• SSL tracking
• DNS/hosting inventory
• Exportable reports

If you tell me roughly how many domains/sites you manage (10, 50, 500+), whether they are your sites or client sites, and whether you resell hosting, I can narrow this to the best 2–3 choices.

1. WHMCS
2. Blesta

A few features I would insist on before choosing:

Yes. If you’re managing a portfolio of sites and want one place for domains, hosting, invoices, renewals, and payment collection, you’re really looking for hosting billing/automation software, rather than a normal hosting control panel.

My shortlist

1. WHMCS — probably what I'd choose

whmcs.com is designed specifically around this model: customers, domains, hosting services, recurring invoices, payments, provisioning and renewals all live in one system. It integrates with domain registrars and hosting control panels, and can automatically invoice for domain renewals and trigger the registrar renewal when payment is received. WHMCS WHMCS

For example, you could structure a client/site as:

• example.com — domain — annual
• Managed WordPress hosting — monthly
• SSL — annual
• Backups — monthly
• Maintenance — monthly
• Email hosting — monthly

Then WHMCS handles the recurring billing and due dates rather than you maintaining a spreadsheet of renewal dates. It also has controls for things like auto-renew on payment, renewal invoices, grace/redemption fees, and domain synchronization. WHMCS Documentation

The big advantage is its ecosystem. If later you want to connect Stripe, a particular registrar, cPanel/Plesk, a support desk, tax software, etc., WHMCS is likely to have an integration.

2. Blesta — very attractive for an agency

blesta.com would be my other serious recommendation.

Its domain manager handles registration, transfers and renewals, with registrar integrations and synchronization. Blesta Its billing engine supports recurring billing, proration, taxes, late fees, automatic payment collection and dunning. Blesta

I'd lean toward Blesta if you're a web agency/portfolio operator rather than trying to become a full hosting company. You get the central billing machinery without necessarily needing the enormous WHMCS ecosystem.

3. HostBill

hostbillapp.com is worth considering if your portfolio gets more complicated—VPS/cloud infrastructure, usage-based billing, multiple service types, etc.

It has extensive domain automation, including registration, renewal, synchronization, nameserver/DNS management and domain locking. HostBill

For a straightforward collection of WordPress/business sites, though, I'd probably not pay for that complexity.

What I'd do in your situation

If your goal is essentially:

"I own/manage 20–200 websites and want one dashboard that tells me what renews when, bills the appropriate person/company, collects payment, and automatically renews the underlying domain/hosting."

I'd start with WHMCS.

If your goal is:

"I'm a small agency and want a leaner system with predictable costs to manage my clients' hosting/domain subscriptions."

I'd investigate Blesta first, then WHMCS.

One important distinction: WHMCS/Blesta don't necessarily provide the underlying hosting or domain registration themselves. Think of them as the billing + orchestration layer sitting above registrars and hosting providers. You can use something like a registrar API plus cPanel/Plesk/another hosting provider underneath, while your clients see one centralized billing system.

If you tell me roughly how many sites you have, whether they're all yours or client-owned, and whether you want to resell hosting or just manage your own portfolio, I can narrow this down to the best 2–3 setups (including registrar + hosting + billing) for your use case.

For a portfolio of sites (agency/client sites, not necessarily a public hosting business), look at hosting billing platforms rather than generic accounting tools.

Top options:

• blesta.com — best fit for many agencies: recurring invoices, domain renewals, hosting provisioning, client portals, payment automation, and multi-company support. Blesta Blesta
• whmcs.com — strongest ecosystem if you manage lots of domains, resell hosting, or need deep registrar/control-panel integrations. WHMCS
• clientexec.com — simpler and often cheaper for smaller portfolios. Panellicense

For your use case, I’d prioritize:

1. Automatic domain renewal tracking (expiry alerts, registrar sync)
2. Recurring client billing (hosting, maintenance, SSL, email)
3. Stripe/ACH autopay
4. Client portal for invoices and service history
5. Separating brands/projects if you manage multiple businesses

If you’re managing ~10–200 sites as an agency, I’d lean Blesta. If you’re effectively becoming a hosting reseller with hundreds/thousands of domains, WHMCS is usually the safer choice. Blesta WHMCS

Also consider keeping domains with a registrar that supports API access (for example, syncing renewals) rather than manually renewing across registrars.

If your goal is one place to manage a portfolio of websites, domains, hosting, renewals, invoices, and payment collection, I’d look at these in this order:

1. WHMCS — best overall

whmcs.com

This is probably the strongest fit if you want serious billing controls, rather than simply a domain-management dashboard.

It can centralize:

• Domains and domain renewals
• Hosting subscriptions
• Recurring invoices
• Automatic payment collection
• Renewal reminders
• Customer/client records
• cPanel, Plesk, and DirectAdmin hosting
• Multiple domain registrars
• Automated provisioning/suspension
• Taxes, pricing, and billing cycles

WHMCS can automatically generate domain-renewal invoices and, after payment, trigger the renewal through the registrar. WHMCS WHMCS Documentation

It also supports 100+ domain registrars and 70+ payment gateways, which is useful if you're building this into an agency/reseller operation rather than just managing your own sites. WHMCS

I'd choose this if: you have dozens+ of sites or expect the portfolio to grow, and you want billing automation to be the central system.

2. ResellerClub — best if you want the domains + hosting provider bundled together

resellerclub.com

ResellerClub is interesting because it combines domains, hosting, email, SSL, DNS, etc. under one reseller account. Its current WebPro panel groups domains, hosting, email and SSL by customer and supports bulk management. ResellerClub© ResellerClub©

You can then connect it to WHMCS, Blesta, Plesk, etc. for the actual billing layer. ResellerClub©

I'd choose this if: you want to buy the underlying domains/hosting wholesale and then bill your own clients.

3. WHMAZ — worth considering for a smaller/self-hosted operation

whmaz.com

WHMAZ is a newer self-hosted alternative that handles hosting provisioning, domains, renewals, client records, invoicing and support. It supports cPanel, Plesk and DirectAdmin. WHMAZ

I'd consider it if WHMCS feels overkill or you specifically want a modern self-hosted system.

What I'd build for your use case

If these are your own portfolio of sites, rather than hosting customers, I'd actually separate the roles:

Registrar → domain ownership/renewal
Hosting provider → servers/sites
WHMCS → central billing + renewal management
Accounting → QuickBooks/Xero/etc.

For example:

50 domains + 30 hosting accounts → WHMCS
↓
One dashboard showing every renewal date
↓
Monthly/annual recurring billing
↓
Automatic payment
↓
Domain/hosting renewal triggered automatically

WHMCS also lets you control whether individual domains auto-renew, generate renewal orders, send notices, and handle grace/redemption fees. WHMCS Documentation WHMCS Documentation

My pick: WHMCS + a good domain/hosting reseller. It gives you considerably more control than simply putting everything under a registrar's "portfolio" dashboard.

If you tell me roughly how many domains/sites you have (e.g. 10, 50, 200+) and whether they're for your own business or multiple clients, I can narrow this down to the best 2–3 setups and approximate monthly cost.

Yes. If you’re managing a portfolio of sites and want one place for domains, hosting, renewals, invoicing, and payment collection, I’d look at WHMCS and Blesta first.

My shortlist

1. WHMCS — safest overall choice

whmcs.com is probably the benchmark if you want a proper billing/operations layer rather than simply a domain registrar.

It can tie together:

• Domain registration and renewals
• Hosting subscriptions
• Recurring invoices
• Automatic payment collection
• Renewal reminders
• Hosting provisioning/suspension
• Multiple domain registrars
• cPanel/Plesk/DirectAdmin
• Client portals and support

Its domain system can synchronize expiration dates, invoice customers for renewals, and trigger the actual registrar renewal after payment. WHMCS WHMCS Documentation

It also has a cloud/managed option, so you don't necessarily have to maintain the billing application yourself. WHMCS

I'd choose WHMCS if: you're building something that may eventually become a small hosting/managed-services business with clients, rather than just tracking your own sites.

2. Blesta — potentially better for a portfolio/agency

blesta.com is particularly interesting for your use case.

Its Domain Manager is explicitly designed around centralizing domains across multiple registrars, with synchronized expiration dates, renewal pricing, automatic renewal invoices, auto-renewal controls, and bulk operations. Blesta

The billing side handles recurring invoices, automatic payments, taxes, proration, late fees and dunning, with 30+ payment gateways. Blesta

And it integrates with hosting systems such as cPanel, Plesk, DirectAdmin and VirtFusion. Blesta

I'd lean toward Blesta if: you have, say, 20–500 sites/domains and want a relatively clean internal system without adopting an enormous enterprise-style platform.

One particularly useful feature is its bulk domain management—you can filter domains by registrar/expiry and bulk-renew or move them between registrars. Blesta

The architecture I'd use

For a portfolio, I'd actually separate registrar from billing/management:

                    ┌── Registrar A
                    ├── Registrar B
Blesta / WHMCS ─────┼── Registrar C
      │             │
      ├── Domain renewals
      ├── Hosting renewals
      ├── SSL renewals
      ├── Recurring invoices
      ├── Payment collection
      └── Renewal alerts
                    │
              Client / Company

That gives you one operational dashboard without locking every domain into a single registrar.

One important distinction

If by "portfolio" you mean your own collection of sites, rather than selling hosting to customers, WHMCS/Blesta may actually be more machinery than you need.

In that case I'd consider a simpler setup where:

one registrar + one hosting provider + centralized expense/billing management

is preferable.

But if you want to eventually say:

"Every site has a domain + hosting + maintenance package, automatically billed annually/monthly, with renewal dates and payment status all in one place"

then Blesta or WHMCS is exactly the category of software I'd use.

My pick: Blesta for a lean portfolio/agency operation; WHMCS if you expect to grow into a real hosting/reseller operation. Blesta WHMCS

If you tell me roughly how many domains/sites you have (e.g. 20, 100, 500+) and whether they're yours or client sites, I can narrow this down to the best 2–3 setups, including the registrar/hosting combination I'd pair with them.

Yes. If the goal is one place to manage domains, hosting, renewals, invoices, and payment collection across a portfolio of sites, I’d look primarily at WHMCS.

My shortlist

1. WHMCS — best overall

• Centralizes domains, hosting services, invoices, payments, and renewals.
• Integrates with 100+ domain registrars and hosting control panels such as cPanel and Plesk. WHMCS WHMCS
• Handles recurring billing, automatic invoices, payment collection, reminders, taxes, refunds, and proration. WHMCS
• Domain renewals can be automatically invoiced and then triggered at the registrar after payment. WHMCS Documentation
• You can bundle a domain with hosting or other services and manage everything from one client/service record. WHMCS Documentation
• Particularly good if you're managing sites for clients and want each client to have a clean billing history.

whmcs.com

2. HostBill — strongest alternative

• Very similar concept, with particularly extensive automation.
• Supports 50+ domain registrar integrations and bulk domain operations such as auto-renewal and nameserver changes. hostbillapp.com
• Has 500+ integrations covering hosting panels, registrars, payment gateways, and other services. hostbillapp.com
• I'd consider it if you want more customization/automation and don't mind a somewhat more hosting-industry-oriented system.

hostbillapp.com

For your particular use case

If you're an agency/portfolio owner rather than a hosting company, I'd structure it something like:

Client / Portfolio
→ Site A
→ Domain renewal
→ Hosting renewal
→ SSL
→ Maintenance
→ Site B
→ Domain renewal
→ Hosting renewal
→ etc.

Then have WHMCS generate one recurring invoice containing the appropriate services, rather than having domains scattered across registrars and hosting bills scattered across providers.

The big advantage is that domain renewal and hosting renewal don't have to occur on the same billing cycle. WHMCS explicitly supports different billing cycles—for example, annual domains alongside monthly hosting. WHMCS Documentation

One important distinction

If you mean "I own 30–100 websites and just want an internal dashboard to track their domains/hosting expenses", I wouldn't necessarily deploy WHMCS. It's somewhat overpowered because it's designed to operate a hosting/billing business.

If instead you mean "I manage websites for clients and want to sell them hosting + domains + maintenance on recurring invoices", WHMCS would be my first choice.

If you tell me roughly how many sites you manage, whether they're yours or client sites, and whether you want to resell hosting, I can narrow this down to the best 2–3 setups (including registrar + hosting provider combinations).

If your goal is one system to manage domains + hosting + recurring billing + renewals across many sites, I’d shortlist these:

1. whmcs.com — best overall for centralized billing

This is probably the strongest fit if you want a proper billing/operations system, rather than merely a hosting dashboard.

• Central client/account database
• Recurring invoices and automatic payment collection
• Domain registration, transfers and renewals
• Integrates with 100+ domain registrars and major hosting panels such as cPanel and Plesk
• Automatic renewal invoices and registrar renewals
• Renewal notices, grace periods and late fees
• Hosting provisioning/suspension based on billing status
• Client portal
• Supports bundling domains with hosting/services WHMCS WHMCS WHMCS Docs

For example, you could structure a client as:

Client A → example.com + hosting + SSL + maintenance
$49/mo, with domain renewal automatically folded into the appropriate billing cycle.

WHMCS is particularly good if you're managing dozens/hundreds of sites or clients and want billing to be the source of truth.

2. wpmudev.com — best if they're predominantly WordPress sites

If this is a portfolio of WordPress sites rather than a general hosting business, WPMU DEV is much more turnkey.

It combines:

• WordPress site management
• Hosting
• Domains
• Client management
• Billing/subscriptions
• Backups/security/updates
• White-label/reseller functionality

Its reseller system lets you create your own hosting/domain products, while billing handles the client invoicing. WPMU DEV WPMU DEV

The big advantage is less infrastructure to assemble. You can manage the sites and the commercial relationship from the same dashboard. WPMU DEV WPMU DEV

3. HostBill — worth considering for a more customized hosting business

I'd investigate HostBill if you want something closer to WHMCS but with a highly configurable billing/catalog/automation layer. It can make sense when you have unusual products, complex pricing, or lots of third-party service integrations.

What I'd choose

My default recommendation is WHMCS if billing controls are the priority. It's specifically designed to make domains, hosting, recurring invoices, payments and renewals part of one lifecycle rather than having you reconcile several systems. WHMCS also now has a fully managed cloud version, so you don't necessarily need to host the billing software yourself. WHMCS www1.whmcs.com

If you tell me roughly how many sites/domains you have, whether they're WordPress, and whether they're your own sites or client sites, I can narrow this down to the best 2–3 setups and show you what the billing architecture would look like.

If you’re managing a portfolio of sites (your own sites or client sites) and want one place for domains, hosting, renewals, invoices, payment methods, and reporting, you’ll usually want either a hosting billing automation platform or a managed agency hosting platform.

Here are the strongest options by use case:

My recommendations by scenario

1. You run many client websites and bill clients monthly

Use WHMCS + a reseller hosting stack.

It can handle:

• recurring hosting invoices
• domain renewals
• SSL/service add-ons
• automatic reminders
• client logins
• payment collection
• hosting provisioning through panels like cPanel/Plesk

WHMCS specifically focuses on automating billing, payments, hosting provisioning, and domain management. WHMCS WHMCS

Typical stack:

• Domain registrar: Namecheap, OpenSRS, Tucows, etc.
• Hosting: reseller VPS/cPanel/Plesk provider
• Billing: WHMCS

2. You have 20–200 sites and just want internal control

I’d lean toward:

• Domains: keep them at a strong registrar
• Hosting: consolidate under one managed provider
• Billing/accounting: use Blesta or accounting software integration

Blesta is designed around billing, domains, provisioning, and client/service management, and supports integrations with hosting panels and registrars. Blesta Blesta

3. You are an agency selling “website care plans”

A very common setup:

• Hosting: managed WordPress/cloud platform
• Domains: registrar account with reseller features
• Billing: WHMCS or Blesta
• Accounting: quickbooks.intuit.com or xero.com

Your monthly package might look like:

Website Care Plan        $99/mo
Hosting                  included
Domain renewal           included
SSL                       included
Backups                   included
Maintenance hours         included

The billing platform handles renewals and failed payments automatically.

Features I would prioritize

For a portfolio, look for:

• ✅ Multiple domains per client/account
• ✅ Automatic renewal reminders
• ✅ Auto-charge cards
• ✅ Domain expiration alerts
• ✅ Registrar API integration
• ✅ Hosting inventory tracking
• ✅ Separate client billing vs internal costs
• ✅ Profit reporting per site
• ✅ Team permissions
• ✅ Export/API access

My shortlist

For most portfolio owners:

1. WHMCS — best if you may resell hosting or manage many clients. WHMCS
2. Blesta — best if you want a cleaner, more agency-friendly billing hub. Blesta
3. Cloudways + accounting software — best if you care more about easy hosting operations than domain/billing automation. TechRadar

A key question: Are these sites yours only, or are you managing/billing sites for clients? The ideal stack changes quite a bit depending on that.

Yes. If your goal is one operational system for domains + hosting + recurring billing + renewals across many sites, I’d look at these three first:

My pick: WHMCS

For what you're describing, WHMCS is probably the strongest fit.

It isn't really a hosting company itself; it's the billing/orchestration layer that sits between your customers, registrar, hosting infrastructure, and payment processor. It integrates with domain registrars and hosting control panels and automates provisioning, invoicing, payments, renewals, suspensions, etc. WHMCS WHMCS

The particularly useful part for your use case is that you can create something like:

Website A
Domain: example.com — $20/year
Hosting: Managed WordPress — $30/month
Maintenance: $75/month
Backups: $10/month
→ one customer invoice / billing relationship

And WHMCS can handle different billing cycles within the same account. It can automatically generate domain-renewal invoices, send renewal notices, and trigger the registrar renewal after payment. WHMCS Docs WHMCS Docs

It also supports domain + hosting bundles, including configurations where a domain is free with a particular hosting product/billing cycle. WHMCS Docs WHMCS Docs

For hosting, WHMCS integrates with systems such as cPanel and Plesk, allowing you to provision/suspend/manage hosting accounts based on billing status. WHMCS

If they're mostly WordPress sites

I'd seriously consider WPMU DEV instead if you're managing, say, 20–100+ WordPress sites and don't need to operate a traditional hosting-reseller business.

WPMU DEV combines WordPress site management, hosting, client management, billing, support, and reseller/white-label functionality in one dashboard. WPMU DEV WPMU DEV

It also offers wholesale domain access and client billing, so it's closer to an agency operating system than WHMCS's more traditional hosting-business operating system. WPMU DEV

The distinction I'd use

Choose WHMCS if:

• You have multiple clients/sites with different services.
• You want granular control over billing.
• You want to use different registrars/hosting providers.
• You want automated domain renewals.
• You may eventually resell hosting/domains.
• You want to build your own packages and pricing.
• You need a proper customer portal and invoices.

Choose WPMU DEV if:

• Almost everything is WordPress.
• You're primarily an agency rather than a hosting company.
• You want hosting + maintenance + backups + updates + billing in one ecosystem.
• You value simplicity over maximum infrastructure flexibility.

One important architectural point: I wouldn't necessarily move all your domains and hosting to the same vendor just to centralize billing. A better setup can be:

Registrar(s) → WHMCS → Hosting provider(s) → Stripe/ACH

That gives you one place to see what is owed, what renews when, which client/site it belongs to, and whether payment has been collected, while keeping the underlying registrar/hosting infrastructure replaceable.

If you tell me roughly how many domains/sites you have (e.g. 20, 100, 500), whether they're mostly WordPress, and whether these are your own sites or client sites, I can narrow this down to the best 2–3 setups and show you what the billing architecture would look like.

For hosting, WHMCS integrates with systems such as cPanel and Plesk, allowing you to provision/suspend/manage hosting accounts based on billing status. WHMCS

If they're mostly WordPress sites

I'd seriously consider WPMU DEV instead if you're managing, say, 20–100+ WordPress sites and don't need to operate a traditional hosting-reseller business.

WPMU DEV combines WordPress site management, hosting, client management, billing, support, and reseller/white-label functionality in one dashboard.

It also offers wholesale domain access and client billing, so it's closer to an agency operating system than WHMCS's more traditional hosting-business operating system.

The distinction I'd use

If your goal is one control center for a portfolio of sites—domains, hosting, renewals, invoices, payments, and client billing—I’d look at WHMCS first, with Blesta as the strongest alternative.

My shortlist

1. whmcs.com — probably what I'd choose

WHMCS is specifically built to make hosting + domains + recurring billing one system. It can provision hosting through systems such as cPanel/Plesk, connect to domain registrars, generate recurring invoices, collect payments, send renewal reminders, and automatically renew domains after payment. WHMCS WHMCS

For a portfolio, the useful model is something like:

Client → Website → Hosting plan + Domain + SSL + Email → recurring invoice → automatic renewal

You can also create bundled hosting products—for example, "Website Care — $99/mo" containing hosting, maintenance, backups, domain management, etc. WHMCS supports free-domain-with-hosting-style bundles and billing-cycle-based products. WHMCS

The big advantage is the ecosystem: WHMCS says it has integrations with 100+ domain registrars and 70+ payment gateways, plus major hosting control panels. WHMCS

2. blesta.com — I'd seriously consider this

Blesta does essentially the same core job: recurring billing, taxes, proration, payment collection, domain registration/renewals, and hosting provisioning. It integrates with cPanel, Plesk, DirectAdmin and domain registrars. Blesta Blesta

The reason I'd consider it over WHMCS is billing economics and control. Blesta is self-hosted and its licensing model can be considerably more attractive if you're managing lots of sites/clients. Blesta

The architecture I'd use

If you're managing, say, 20–200+ websites, I wouldn't necessarily look for a single company that sells the actual hosting and billing software.

I'd separate the layers:

Billing/operations:
→ WHMCS or Blesta

Domain registrar:
→ OpenSRS, Namecheap/Enom, Tucows, etc.

Hosting infrastructure:
→ cPanel/Plesk/DirectAdmin, or a managed hosting provider

Payments:
→ Stripe/ACH/PayPal

Then your billing system becomes the source of truth.

For example:

                    WHMCS / Blesta
                         │
          ┌──────────────┼──────────────┐
          ↓              ↓              ↓
       Domains         Hosting        Payments
       Registrar       cPanel         Stripe
          │              │              │
       renewals       provisioning    collection
          └──────────────┼──────────────┘
                         ↓
                   Client portal

That gives you a single place to see:

• Domain expiration dates
• Hosting renewal dates
• What each site costs you
• What each client is being charged
• Recurring revenue
• Failed payments
• Upcoming renewals
• Automatic renewal status
• Invoices and payment history
• Which services belong to which client/site

One particularly important distinction: if this is your own portfolio of sites, rather than a hosting business with many external customers, you may not need the full WHMCS/Blesta machinery. In that case, a simpler billing/asset-management setup could be better.

If you tell me roughly how many domains/sites you have, whether they're for your own portfolio or clients, and whether you want to resell hosting, I can narrow this down to the 2–3 best setups and the cheapest practical architecture.

Yes. What you’re describing is essentially hosting/domain management + subscription billing + renewal automation in one system. For a portfolio of sites, I’d look at these first:

My pick: WHMCS

If you have, say, 20–200+ domains/sites and want one administrative system, I'd lean toward WHMCS.

It can centralize:

• Domains and their expiration dates
• Domain auto-renewals
• Hosting subscriptions
• Recurring invoices
• Automatic payment collection
• Renewal reminders
• Taxes/VAT
• Credits, refunds and prorations
• Client accounts
• Hosting provisioning/suspension
• Multiple domain registrars
• cPanel/Plesk and other hosting platforms

WHMCS specifically supports automatic domain-renewal invoicing and can trigger the registrar renewal after payment, while keeping domain and hosting billing in the same client account. WHMCS Documentation WHMCS

It also supports things like bundling a free/discounted domain with a hosting product, which is useful if your sites have standardized packages. WHMCS

whmcs.com

Blesta is the one I'd seriously compare against it

blesta.com is particularly interesting if this is primarily for your own portfolio/agency rather than running a giant public hosting business.

Its domain manager lets you have multiple registrars feeding into one pricing/renewal system, with expiration synchronization, automated renewal invoices, reminders, and bulk management. Blesta

Its billing system also supports recurring invoices, automatic payment collection, taxes, proration, late fees and 30+ payment gateways. Blesta

The nice architectural distinction is:

Registrar = where you actually buy the domains
Hosting provider = where the websites run
Blesta/WHMCS = the control plane that tracks everything and handles billing/renewals

That means you don't necessarily have to move all your domains and hosting to one vendor.

What I'd build for a portfolio

For example:

WHMCS/Blesta
→ Client/company
→ Site A
→ .com domain
→ hosting
→ SSL
→ backups
→ monthly management fee

→ Site B
→ .org domain
→ hosting
→ SSL
→ monthly management fee

Then you can have one invoice containing:

Website A hosting — $25/mo
Website A maintenance — $50/mo
Website B hosting — $30/mo
Domain A renewal — $18/yr
Domain B renewal — $20/yr

And have the system automatically remind you/client about upcoming renewals and collect payment.

One important distinction

If by "portfolio of sites" you mean sites you personally own, rather than sites you're reselling hosting for to clients, I'd actually consider whether you need the full WHMCS machinery.

If you're managing 10–50 sites for yourself, a simpler setup can be better: a registrar with good bulk domain management + one hosting provider + accounting/subscription billing software.

If you're managing sites for clients and charging them recurring fees, I'd strongly favor WHMCS or Blesta.

My rough ranking for your use case:

1. WHMCS — best mature all-in-one choice
2. Blesta — best if you want a cleaner/self-hosted, agency-oriented control plane
3. HostBill — worth investigating if you have complicated products/billing
4. A registrar + accounting software — better if this is just your own portfolio and you don't need hosting automation

If you tell me roughly how many domains/sites you have, whether they're client-owned or yours, what hosting you use (Cloudflare/cPanel/Plesk/VPS/etc.), and whether you need to bill clients, I can narrow this down to the best architecture rather than just the best software.

If your goal is one place to manage a portfolio of domains + hosting + renewals + client billing, I’d shortlist these:

My pick: WHMCS

For a portfolio of sites, WHMCS is probably the safest choice if you want something that can grow into a proper centralized billing system.

It can keep domains, hosting services, invoices, payments and client accounts together, while integrating with domain registrars and hosting control panels. WHMCS WHMCS

The particularly useful pieces for your situation are:

• Automatic domain-renewal invoicing and registrar-side renewal after payment. WHMCS Documentation
• Recurring billing, payment collection, reminders, taxes, refunds and proration. WHMCS
• Hosting + domain bundles — e.g. Website Hosting $25/mo + domain $15/year.
• cPanel/Plesk/DirectAdmin integrations for provisioning and suspension when billing status changes. WHMCS WHMCS
• Centralized client portal where services, domains and invoices live together.
• Registrar integrations, so you aren't manually tracking expiration dates across registrar accounts.
• Multiple payment gateways and currencies.

One especially relevant feature is that WHMCS supports free domains bundled with hosting packages, as well as domain markup and automated renewal workflows. WHMCS

Blesta is the one I'd seriously compare against it

blesta.com has become a very compelling alternative. It's self-hosted, and its current version has recurring billing, automatic payments, dunning, taxes, multiple gateways, domain registrar integrations and hosting provisioning. Blesta Blesta

Its domain manager can synchronize registrar pricing/expiration information and apply your markup rules, while its order system explicitly supports selling hosting + domains as a bundle. Blesta Blesta

I'd lean Blesta if you want more control over the software and infrastructure and don't need WHMCS's enormous ecosystem.

For a portfolio of sites specifically

If these are your own sites rather than customers you're reselling hosting to, there's an important distinction.

You may not actually need a full hosting-billing platform. Your ideal setup could instead be:

Registrar(s)
→ domains + auto-renewals

Hosting provider
→ all hosting accounts

Billing/finance system
→ one dashboard for recurring costs, renewal dates, invoices and payment methods

Whereas if you're billing clients for hosting/domain management, I'd go with:

WHMCS → Registrar + cPanel/Plesk + Stripe

That gives you a proper service catalog such as:

Client A
├── example.com — domain renewal — $18/year
├── Website hosting — $30/month
└── Maintenance — $75/month

Client B
├── example.net — domain renewal — $20/year
└── Website hosting — $30/month

and lets the system generate/collect the recurring charges rather than you maintaining a spreadsheet.

If you tell me roughly how many domains/sites you have (e.g. 20, 100, 500), whether they're your sites or client sites, and where they're currently hosted/registered, I can recommend the exact setup—including which registrar/hosting combination gives you the cleanest centralized billing.

Yes. If your goal is one place to manage domains, hosting, renewals, recurring invoices, and client billing across a portfolio, I’d look at these first:

1. whmcs.com — best overall for serious billing control

This is probably the closest match to what you're describing. WHMCS is specifically built around hosting + domains + billing automation, rather than being primarily a website-management tool.

It can handle:

• Domain registration, transfers, renewals and nameserver management
• Hosting provisioning through cPanel, Plesk, DirectAdmin, etc.
• Recurring invoices and automatic payment collection
• Automated renewal reminders
• Automatic suspension for unpaid hosting
• Bundling domains with hosting products
• Client portals and service management
• Stripe, PayPal and other payment gateways
• Taxes/VAT, coupons, proration and refunds
• Multiple billing cycles and currencies WHMCS WHMCS WHMCS

Importantly, you can separate your actual infrastructure from the billing layer. For example:

Registrar → hosting provider → WHMCS → your clients

WHMCS can talk to the registrar and hosting control panel and make the whole thing appear as one service to the client. WHMCS

Current pricing starts at $34.95/month for up to 250 active clients on the listed Plus plan. WHMCS

2. wpmudev.com — better if this is mostly WordPress

If your portfolio is predominantly WordPress sites and you're looking for site management + hosting + client billing rather than building a mini hosting company, WPMU DEV is very compelling.

Its Hub combines site management, hosting, client management, billing, support, updates and backups. It also has a white-label/reseller offering where you can sell hosting and services under your own brand. WPMU DEV WPMU DEV

The distinction I'd make is:

What I'd choose

If you have, say, 20–200 sites and want to turn hosting/domain renewals into standardized packages, I'd choose WHMCS.

You could create products such as:

• Website Care — $99/mo

• Hosting
• SSL
• Backups
• Monitoring
• Support
• Website + Domain — $129/mo

• Everything above
• Domain registration/renewal
• Managed WordPress — $179/mo

• Hosting
• Domain
• Updates
• Backups
• Security
• Maintenance

Then WHMCS handles the recurring billing and renewal machinery behind those packages. Its domain system can also automatically renew domains after the corresponding invoice is paid. WHMCS WHMCS Documentation

One important architectural point: I wouldn't necessarily move every domain and website to the same provider just to centralize billing. I'd centralize the billing/management layer and retain flexibility over where domains and sites are actually hosted.

If you tell me roughly how many sites/domains you have, whether they're mostly WordPress, and whether you're billing clients monthly, I can recommend a specific stack (registrar + hosting + billing platform) and show you how I'd structure the renewals.

Its Hub combines site management, hosting, client management, billing, support, updates and backups. It also has a white-label/reseller offering where you can sell hosting and services under your own brand. wpmudev.com wpmudev.com

Yes. If your goal is one place to manage domains, hosting, recurring billing, renewals, and client/site-level accounting, I’d look at WHMCS and Blesta first.

My shortlist

1. WHMCS — best overall

whmcs.com

For a portfolio of sites, WHMCS is probably the safest choice if you want a proven hosting-billing system.

It can tie together:

• Domain registrations and renewals
• Hosting subscriptions
• Recurring invoices
• Automatic payment collection
• Renewal notices
• Hosting provisioning/suspension
• Multiple domain registrars
• cPanel/Plesk/DirectAdmin
• Stripe and other payment gateways
• Client portals and support

Its domain system can automatically generate renewal invoices and, after payment, send the renewal command to the registrar. You can also control renewal notices, grace periods, pricing and auto-renew behavior. WHMCS WHMCS Documentation

I'd choose WHMCS if: you expect this portfolio to become a real managed-hosting/agency operation, or you want maximum integration options.

2. Blesta — my pick for a smaller agency/portfolio

blesta.com

Blesta is particularly interesting if you're managing your own collection of sites plus clients rather than trying to become a giant hosting company.

It supports recurring invoices, automatic payments, taxes, late fees, multi-currency, and 30+ payment gateways. Blesta

Its Domain Manager is also quite good: registrar integrations, registration/transfer/renewal pricing, automatic registrar synchronization, and bulk renewal/management. Blesta Blesta

It integrates with hosting panels such as cPanel, Plesk and DirectAdmin and can provision/suspend services based on billing status. Blesta

A particularly useful feature for a portfolio is multi-company/multi-brand support: one installation can manage separate brands with their own branding, currencies, gateways, taxes and email templates. Blesta

Blesta's current published pricing starts around $17.95/month for the branded version and $20.95/month for unbranded. Blesta

What I'd actually build

For, say, 20–200 websites, I'd structure it something like:

Blesta/WHMCS → registrar → DNS → hosting provider → sites

Then each site/domain becomes an asset/service with:

• Domain expiration date
• Hosting renewal date
• SSL renewal
• Monthly/annual cost
• Client/customer
• Billing status
• Registrar
• Hosting server
• Automatic renewal setting

You can then have the system generate one consolidated invoice containing something like:

Example Client
example.com — domain renewal — $18
Managed hosting — annual — $240
Maintenance — annual — $600
SSL — included
Total: $858

That is much cleaner than having domains at one registrar, hosting at another, and renewal reminders scattered across email/calendar.

One important distinction

If these are your own sites, rather than sites you're reselling hosting to clients, you may not actually need WHMCS/Blesta. Those systems are designed heavily around selling and billing hosting services.

If what you really want is:

“I own 50 domains/sites and want a centralized dashboard that tracks all renewal costs, automatically renews them, and charges one corporate card/account.”

then I'd look at a domain/hosting management stack rather than a hosting billing platform.

If you tell me roughly how many domains/sites you have, whether they're yours or client-owned, and whether you want to charge clients, I can narrow this down to the 2–3 best setups and explain exactly how I'd structure the billing.

Blesta/WHMCS → registrar → DNS → hosting provider → sites

Then each site/domain becomes an asset/service with:

• Domain expiration date
• Hosting renewal date
• SSL renewal
• Monthly/annual cost
• Client/customer
• Billing status
• Registrar
• Hosting server
• Automatic renewal setting

You can then have the system generate one consolidated invoice containing something like:

If you’re managing a portfolio of sites and want one place for domains, hosting, renewals, invoices, and payment collection, I’d shortlist these:

1. My top pick: WHMCS

whmcs.com

If your goal is "I want a single billing system for 20–200+ domains/sites and don't want to manually track renewals," WHMCS is probably the strongest fit.

It can:

• Keep domains, hosting services, and clients in one account.
• Automatically generate domain renewal invoices.
• Send renewal reminders.
• Automatically renew a domain after the invoice is paid.
• Handle recurring hosting subscriptions.
• Connect to domain registrars and hosting control panels.
• Support Stripe and numerous other payment gateways.
• Let you create bundles, e.g. Domain + Hosting + SSL + Maintenance = $X/year.
• Handle different billing cycles, such as annual domains + monthly hosting.
• Give you proper invoices, payment history, client portals, reporting, etc. WHMCS WHMCS Documentation

The important distinction is that WHMCS is really a billing/automation layer, rather than simply a hosting provider. You can choose your registrar and hosting infrastructure and have WHMCS orchestrate them.

That makes it particularly attractive if you don't want your entire business tied to one hosting company.

2. If everything is WordPress: WPMU DEV

wpmudev.com

This is worth serious consideration if your portfolio is predominantly WordPress sites.

WPMU DEV combines:

• WordPress site management
• Hosting
• Domains
• Client management
• Billing
• Recurring subscriptions
• Client portal
• White-label/reseller functionality

Their current platform specifically lets you create hosting/domain products and sell them to clients, with billing handled through the same system. WPMU DEV WPMU DEV

It also has 270+ wholesale domains available through its platform. WPMU DEV

So if you're an agency thinking:

"I manage 50 WordPress sites and want to bill each client $X/month for hosting, domain, maintenance and support."

WPMU DEV is considerably simpler than building a WHMCS stack.

3. WHMCS + Plesk/cPanel if you're building a real hosting operation

If you have your own VPS/dedicated servers or want more control, I'd look at:

WHMCS → billing/client layer
Plesk or cPanel → hosting/server layer
Registrar/reseller → domains

WHMCS integrates with major hosting control panels and 100+ domain registrars, so you can automate provisioning rather than manually creating accounts. WHMCS

That's the architecture I'd favor if you expect the portfolio to become a real recurring-revenue hosting business rather than simply managing your own sites.

What I'd choose

If these are your own sites: I'd actually avoid overengineering this with WHMCS unless you need client-facing billing.

If these are sites you manage for clients:
→ WPMU DEV if they're primarily WordPress and you want simplicity.

If you're effectively becoming a hosting/maintenance provider:
→ WHMCS + your preferred hosting + domain reseller.

If you want maximum control over billing:
→ WHMCS. Its domain renewal system is particularly mature: renewal invoices, reminders, per-domain auto-renew settings, pricing, grace periods, and registrar-side renewal automation are all configurable.

One important consideration: don't confuse "domain auto-renewal" at the registrar with "billing auto-renewal." WHMCS can be configured so that the customer pays your renewal invoice first, and then WHMCS tells the registrar to renew the domain. That gives you much better control over whether you're paying renewal costs for inactive/unpaid clients.

If you tell me roughly how many sites/domains you have (e.g. 10, 50, 200), whether they're WordPress, and whether you're billing clients monthly/annually, I can narrow this down to the best 2–3 setups and show you what the actual architecture would look like.

For a portfolio of sites (especially if they are your own properties rather than a public hosting business), you’ll usually want a system that can:

• Track every domain expiration date
• Centralize renewal billing
• Store registrar/hosting/vendor records
• Automate invoices and reminders
• Handle multiple clients/brands if you later resell services
• Give you reporting on recurring costs

There are two main approaches:

Best fit if you manage many sites for yourself or an agency

Atera or similar PSA tools

Good when your sites are part of a broader managed-services operation:

• Asset tracking
• Vendor tracking
• Recurring billing
• Client management
• Ticketing

However, these are not domain registrars, so you would still connect them to registrars/hosting providers.

Best fit if you want “hosting company style” control

WHMCS

whmcs.com

Probably the most mature option if you want a true domain + hosting billing hub.

Strengths:

• Domain registration/renewals
• Hosting account provisioning
• Recurring invoices
• Payment collection
• Client portals
• Registrar integrations
• cPanel/Plesk integrations
• Automated suspension/reminders

WHMCS is built around automating the full hosting lifecycle, including billing, provisioning, and domain management. WHMCS WHMCS

Best for:

• Web agencies with many client sites
• Resellers
• Managed hosting businesses
• Portfolios where each site has separate billing

Downside:

• More complexity than many site owners need.

Blesta

blesta.com

A strong WHMCS alternative, especially if you prefer a cleaner/self-hosted system.

Strengths:

• Recurring billing
• Domain renewals
• Hosting provisioning
• Client management
• Registrar integrations
• Multi-brand support options

Blesta specifically focuses on billing, provisioning, domains, and automation in one self-hosted platform. Blesta Blesta

Best for:

• Agencies
• Smaller hosting operations
• Developers who want more control

If you mainly need internal renewal management (not client billing)

Consider:

BILL Manager alternatives:

• Bonsai
• FreshBooks
• Zoho Books
• A spreadsheet/database in Airtable

You would track:

• Domain registrar
• Renewal date
• Annual cost
• DNS provider
• Hosting provider
• SSL provider
• Client/site owner
• Payment method

This is often enough for a portfolio of 10–100 sites.

A setup I would recommend for a portfolio of sites

Option A — Agency / professional management

• Registrar: Cloudflare or Namecheap
• Hosting: VPS/cloud provider
• Billing hub: WHMCS or Blesta
• Accounting: QuickBooks/Xero integration

Option B — Your own portfolio only

• Registrar consolidation
• Central DNS management
• Airtable/Notion asset database
• Accounting software for expenses
• Calendar alerts for renewals

Option C — You plan to sell maintenance packages

• WHMCS or Blesta from the beginning

A key question is: are these sites all yours, or do you manage sites for clients and bill them? The best platform choice changes quite a bit based on that.

If your goal is one place to manage a portfolio of websites, domains, hosting, invoices, and renewals, I’d shortlist these:

1. blesta.com — my pick for an agency/portfolio

Blesta is particularly well suited if you're managing sites for multiple clients and want strong control over billing.

• Domains + hosting in the same system: domain registration, renewal and transfer can be tied to registrar APIs, while hosting can provision through cPanel, Plesk, DirectAdmin, etc. Blesta Blesta
• Automated renewals: it syncs actual domain expiration dates, sends renewal reminders, generates invoices and can auto-charge/renew. Blesta
• Good billing controls: recurring invoices, automatic payments, proration, taxes, late fees, dunning and 30+ payment gateways. Blesta
• Multiple brands/companies: one installation can support separate brands with their own branding, currencies, gateways, taxes and email templates. Blesta
• Bulk domain management: useful when you get into hundreds/thousands of domains—filter by registrar/expiration and bulk renew or move domains. Blesta
• Current pricing starts around $17.95/month, with unlimited clients/staff. Blesta

For a web agency, I'd structure it roughly as:

Client → Websites → Hosting subscription + Domain subscription + optional maintenance → recurring invoice → automatic payment → automated renewal

That gives you a single source of truth instead of keeping domains at one registrar, hosting at another, and billing in QuickBooks/Stripe/spreadsheets.

2. whmcs.com — best if you're building a more traditional hosting operation

WHMCS is the established heavyweight in this category. It handles customers, services, domains, invoices, recurring billing, payment collection, hosting provisioning and registrar integrations. WHMCS

Its domain renewal system is particularly mature: renewal invoices, notices, grace periods, pricing controls and automated registrar renewal are built in. WHMCS Documentation

I'd lean WHMCS if you're effectively becoming a hosting/reseller business with lots of automated provisioning.

3. Blesta vs. WHMCS for your use case

My recommendation: start with Blesta unless you already have a substantial WHMCS ecosystem. Its current domain manager is unusually good for exactly what you're describing: centralized registrar management, renewal dates, pricing, automatic invoicing and bulk operations. Blesta

One important distinction: Blesta/WHMCS are billing + provisioning platforms, not necessarily the registrar/hosting provider themselves. You'd connect them to registrars such as NameSilo, OpenSRS, Namecheap, etc., and to your hosting infrastructure. Blesta, for example, supports 12 first-party registrar modules. Blesta

If you tell me roughly how many domains/sites you manage (e.g. 20, 100, 500+) and whether they're your own sites or client sites, I can recommend the exact stack—including registrar + hosting + billing + payment processor—that I'd use.

Yes. If you’re managing a portfolio of websites and want one place for domains, hosting, renewals, invoices, and payment collection, I’d look at hosting-management/billing platforms rather than a normal accounting app.

My top pick: WHMCS

whmcs.com is probably the strongest fit if you want to build a centralized system around domains + hosting.

It can handle:

• Domains: registrations, transfers, renewals, DNS, WHOIS, expiration tracking
• Hosting: cPanel/Plesk and other hosting provisioning
• Recurring billing: monthly/annual billing, invoices, payment collection and reminders
• Renewal automation: automatically invoice and renew domains/services
• Bundles: e.g. Domain + Hosting + SSL + Maintenance as one customer/service package
• Multiple registrars: WHMCS supports a large number of domain registrars, so you don't necessarily have to move every domain to the same registrar. WHMCS WHMCS Documentation
• Client portal: useful if you're managing sites for clients and want them to see their domains, hosting, invoices, etc.
• Centralized reporting: customers, services, invoices and billing activity in one system. WHMCS

For example, you could structure your portfolio like:

And have WHMCS generate/manage the recurring charges rather than maintaining a spreadsheet of renewal dates.

One particularly useful feature

WHMCS can associate a free/included domain with a hosting package, which is useful if you want to sell or internally structure bundles such as "Hosting includes domain." WHMCS

It also supports automated domain renewal workflows where payment triggers the registrar renewal. WHMCS Documentation

The alternatives I'd consider

Blesta — worth looking at if you're primarily interested in billing/client management and want something somewhat leaner and potentially less expensive.

HostBill — more interesting if you're managing a larger/more complicated hosting operation, especially cloud/VPS infrastructure.

ClientExec — simpler option if you don't need the enormous ecosystem around WHMCS.

For a portfolio of, say, 10–100+ websites, I'd personally shortlist WHMCS vs. Blesta first.

Important distinction

If these are your own sites, rather than sites you're selling hosting to customers, you may not actually need a full hosting-billing platform.

In that case I'd consider a different architecture:

Domain registrar/reseller account → centralized hosting provider → billing/accounting system → renewal monitoring

Whereas if you're billing clients for their websites, WHMCS becomes much more compelling because it is designed to make the domain/hosting/service relationship itself billable and automated. WHMCS

If you tell me roughly how many domains/sites you have, whether they're yours or client-owned, and whether you want to resell hosting, I can narrow this down to the 2–3 best setups and show you exactly how I'd structure the billing/renewal system.

Yes. If you have a portfolio of sites and want one operational system for domains + hosting + renewals + client billing, I’d look at WHMCS first, with Blesta as the strongest alternative.

My shortlist

1. WHMCS — probably your best fit

WHMCS is essentially an ERP-lite for hosting/domain operations.

You can centralize:

• Domains and expiration dates
• Domain renewals and auto-renewals
• Hosting subscriptions
• Recurring invoices
• Credit cards/payment methods
• Automatic payment collection
• Renewal reminders
• Taxes/VAT
• Discounts and bundled products
• Client accounts
• Hosting provisioning
• cPanel/Plesk/DirectAdmin integration
• Multiple domain registrars

WHMCS specifically supports domain renewal invoicing and can automatically send the renewal command to your registrar after payment. WHMCS WHMCS Documentation

It also supports bundling domains with hosting packages, which is useful if your sites are sold/managed as packages rather than as completely independent services. WHMCS

For example, you could structure an account like:

Acme Website
Domain: acme.com — $18/year
Hosting: Managed WordPress — $30/month
SSL — included
Maintenance — $75/month
Total recurring billing: $105/month + annual domain renewal

And have WHMCS handle the invoices, payment collection, reminders and renewal workflow.

WHMCS also now offers a fully managed cloud version if you don't want to maintain the billing application yourself. WHMCS

whmcs.com

2. Blesta — my alternative pick

Blesta is particularly interesting if you're an agency or portfolio operator rather than a traditional hosting company.

Its domain manager can centralize multiple registrars and maintain registration/renewal/transfer pricing, expiration synchronization and bulk domain operations. Blesta

Its billing system handles recurring invoices, automatic payments, taxes, late fees, proration and multiple payment gateways. Blesta

The big advantage is that Blesta is self-hosted, so you retain more control over the application and data. Blesta

blesta.com

What I'd choose for your situation

If you're managing 10–100+ websites, I'd probably choose:

WHMCS + a domain registrar + your preferred hosting infrastructure

rather than trying to find a single registrar/host that does everything.

The important architectural distinction is:

WHMCS/Blesta = your central billing & operations layer
Registrar = where domains actually live
Hosting provider/server = where websites actually run

That means you aren't locked into one hosting company. You can potentially have domains at one registrar, WordPress sites on another infrastructure provider, VPSs somewhere else, while WHMCS remains the single source of truth for what each site costs, when it renews, and who pays for it.

For a portfolio where you are the owner/operator rather than reselling hosting to customers, I'd lean Blesta if you want a leaner self-hosted system; WHMCS if you want the deepest integrations and automation ecosystem. WHMCS currently advertises 100+ registrar integrations, 70+ payment gateways and integrations with cPanel, Plesk and DirectAdmin. WHMCS WHMCS

If you tell me roughly how many domains/sites you have (e.g. 20, 100, 500), whether they're for your own businesses or clients, and whether you use WordPress/cPanel/etc., I can narrow this down to the best setup and suggest the registrar + hosting combination too.

For a portfolio of sites (your own sites or client sites), you usually want billing automation + domain renewal tracking + hosting inventory, rather than a simple registrar account. The best fit depends on whether you are acting like a hosting provider, an agency, or just managing assets.

Best overall options

whmcs.com — best for a serious hosting/domain operation

Best if: you manage many domains, hosting accounts, clients, subscriptions, or want to resell hosting.

Strengths:

• Central client portal
• Recurring invoices and payment collection
• Automatic domain renewal workflows
• Registrar integrations
• Hosting provisioning integrations (cPanel, Plesk, etc.)
• Service suspension/reactivation rules
• Tax, coupons, invoices, reporting WHMCS WHMCS

Typical setup:

• Registrar account(s) → WHMCS → hosting providers/servers → clients
• One dashboard showing domains, renewal dates, invoices, and services

Downside:

• More complexity than many portfolio owners need.
• Pricing and licensing can add up.

blesta.com — best WHMCS alternative for smaller operators

Best if: you want strong billing controls but prefer a simpler/self-hosted system.

Strengths:

• Self-hosted
• Recurring billing
• Domain management
• Hosting provisioning modules
• Client management
• Automation tasks for invoices, reminders, provisioning, and renewals Blesta Blesta

Good fit for:

• Freelancers
• Agencies managing dozens/hundreds of sites
• Small hosting businesses

clientexec.com — easier hosting billing platform

Best if: you want something lighter than WHMCS.

Good for:

• Hosting packages
• Domain sales
• Basic customer billing
• Smaller portfolios

hostbillapp.com — highly customizable

Best if: you have unusual workflows or a larger infrastructure.

Strengths:

• Broad automation
• Lots of integrations
• More enterprise-style workflows

Downside:

• More setup effort.

If these are your own portfolio sites (not customers)

A full hosting billing system may be overkill. Consider:

• Keep domains centralized at one registrar (for example, a registrar with portfolio management)
• Use a monitoring/asset management tool for expiration dates
• Use accounting software for costs
• Use a password manager with domain/hosting metadata

You may not need customer invoicing, provisioning, or client portals.

My recommendation by scenario

A good architecture is usually:

Registrar(s) → Billing platform (WHMCS/Blesta) → Hosting providers → Accounting/reporting

If you tell me roughly:

1. number of domains/sites,
2. whether they are yours or client-owned,
3. whether clients pay you recurring fees, and
4. whether hosting is on shared hosting, VPS, or cloud,

I can narrow it to a specific stack.

For a portfolio of sites (especially if you manage domains, hosting, SSLs, maintenance plans, and client billing), you usually want a hosting automation + billing platform rather than just a registrar account. The best fit depends on whether you are managing your own sites or reselling services to clients.

Strong options

1. WHMCS — best overall for agencies and hosting portfolios

whmcs.com

Best for: agencies, MSPs, freelancers with many client sites, small hosting companies.

Why it fits:

• Central client/service database
• Recurring invoices and automatic renewal reminders
• Domain registration, transfers, and renewals through registrar integrations
• Hosting provisioning integrations (cPanel, Plesk, etc.)
• Client portal for billing/support
• Add-ons like SSL, backups, maintenance packages, email hosting, etc. WHMCS WHMCS

A typical setup:

• Registrar → domains
• Hosting provider/VPS → servers
• WHMCS → billing, renewals, customer records, automation

This is probably the closest match if your goal is “one dashboard for everything.”

2. HostBill — more enterprise/customizable

Best for: larger operations needing deeper workflows.

Similar to WHMCS:

• Billing automation
• Domain management
• Hosting provisioning
• Support workflows

It tends to appeal to businesses that want more customization, though WHMCS has a larger ecosystem.

3. Blesta — simpler and cleaner

Best for: smaller portfolios where you want less complexity.

Pros:

• Good billing/subscription management
• Domain and hosting integrations
• Cleaner interface than some heavier systems

Cons:

• Smaller ecosystem than WHMCS

4. Managed WordPress platforms + separate billing

If most of your portfolio is WordPress sites and you are not selling hosting, you may not need a full hosting automation system.

Common stack:

• Managed WordPress host
• Domain registrar
• Accounting/billing platform
• Client management tool

This is simpler, but renewals are usually less centralized.

What I would choose by scenario

Features worth prioritizing

For your use case, look for:

• Automatic domain renewal tracking
• Expiration alerts (60/30/7 days)
• Multiple registrar support
• Multiple hosting-provider support
• Recurring invoices
• Client ownership/history of domains
• Cost vs. revenue reporting per site
• Payment gateway automation
• API access for custom dashboards

A practical architecture many agencies use:

Domain registrar(s) → WHMCS → hosting providers/VPS → accounting/payment system

That gives you one place to see “Site A has domain renewal in March, hosting renewal in April, SSL renewal in May, and client invoice status.”

If you tell me whether these are your own portfolio sites or client sites you manage/resell hosting for, and roughly how many domains (10, 50, 500+), I can narrow the recommendation.

A practical architecture many agencies use:

Domain registrar(s) → WHMCS → hosting providers/VPS → accounting/payment system

If you tell me whether these are your own portfolio sites or client sites you manage/resell hosting for, and roughly how many domains (10, 50, 500+), I can narrow the recommendation.

Yes. For a portfolio of sites, I’d separate the billing/control layer from the registrar/hosting provider rather than looking for one company that does everything.

My top pick: WHMCS + a registrar/host

whmcs.com is probably the closest fit to what you're describing.

It can centralize:

• Domains — registrations, transfers, renewals, expiry tracking, DNS/nameserver management
• Hosting — provisioning and management through cPanel, Plesk, DirectAdmin, etc.
• Recurring billing — invoices, automatic payment collection, failed-payment reminders
• Bundling — e.g. Domain + Hosting + SSL + Maintenance as one client/service package
• Renewal automation — domain renewal invoices and registrar renewal actions can be automated
• Client/site-level records — useful if you're managing sites for multiple clients
• Payment gateways and taxes — including recurring payments and invoicing
• Client portal/support — customers can see their domains, hosting, invoices, and services in one place. WHMCS WHMCS

WHMCS also has a cloud-hosted version, so you don't necessarily need to maintain the billing server yourself. WHMCS

A good architecture

I'd consider something like:

WHMCS
↓
Domain registrar: OpenSRS / another registrar with API
↓
Hosting: your preferred VPS/cloud/cPanel provider
↓
Payments: Stripe/PayPal/etc.

For example, opensrs.com is particularly interesting if you want a wholesale domain layer. It supports domains, DNS, email and SSL, has bulk management, and specifically provides plugins for WHMCS and other billing platforms. OpenSRS OpenSRS

That gives you one billing dashboard without locking all your infrastructure to one vendor.

If this is mostly your own portfolio

There's an important distinction.

If you're managing 50–500 sites that you own, rather than reselling hosting to clients, WHMCS may actually be more software than you need. In that case I'd look for a simpler asset/renewal management + accounting setup.

If you're managing sites for clients and charging them annually/monthly, WHMCS becomes much more compelling because it is designed around exactly this model.

A typical client could have:

Example.com
Domain — $20/year
Hosting — $240/year
SSL — included
Maintenance — $50/month
Backups — $10/month

…and WHMCS can treat those as separate services while putting them under the same customer and automating the billing/renewal cycle. WHMCS WHMCS

Another option: OpenSRS alone

If your main problem is domain centralization, rather than client billing, OpenSRS is worth considering.

Its reseller control panel is designed for agencies/MSPs managing large portfolios and supports bulk renewals, bulk DNS changes, permissions, domain management, etc. It also has no monthly/annual platform fee. OpenSRS

But I'd choose WHMCS + OpenSRS if you need serious billing controls.

What I'd choose

If you tell me roughly how many domains/sites you have (e.g. 20, 100, 500), whether they're yours or client sites, and whether you want to charge clients monthly/annually, I can narrow this down to 3–4 platforms and compare their actual costs and billing/renewal capabilities.

Yes. If your goal is one operational system for domains + hosting + recurring billing + renewals across many sites, I’d put WHMCS at the top of the list.

whmcs.com is specifically built as the business/billing layer for hosting and domain providers. It can manage recurring invoices, payments, renewal reminders, domain renewals, hosting provisioning, client accounts, and support in one place. WHMCS WHMCS

What I’d consider

Why WHMCS fits your use case

You can structure each site as a customer/service relationship, for example:

• client.com - Domain — annual renewal
• Hosting — monthly/annual
• SSL — annual
• Maintenance — monthly
• client2.com - Domain — annual
• Hosting — annual
• Maintenance — monthly

WHMCS can generate recurring invoices, collect payments, send overdue/renewal notifications, and automate the actual domain renewal after payment. It also supports different billing cycles, proration, late fees, taxes, discounts, refunds, and multiple payment gateways. WHMCS WHMCS Documentation

For hosting, it integrates with control panels such as cPanel and Plesk, allowing hosting accounts to be provisioned, suspended, modified, and terminated based on billing status. WHMCS WHMCS

The important distinction is that WHMCS isn't really the registrar or hosting infrastructure itself. Think of it as the central billing/operations layer sitting above your registrar and hosting providers.

A typical architecture would be:

WHMCS → domain registrar + hosting provider + Stripe/PayPal

For domains, you could use a reseller such as opensrs.com, which supports automated registrations, renewals, transfers and WHOIS management and has WHMCS integration. OpenSRS OpenSRS

If these are your own sites

There's an important wrinkle: if you're managing, say, 20–200 sites that you own, rather than selling hosting to clients, WHMCS may actually be more machinery than you need.

In that case I'd look for a setup that gives you:

centralized domain portfolio + renewal calendar + automatic payment + hosting subscriptions + consolidated accounting

rather than a full customer-facing hosting-reseller platform.

If you tell me roughly how many domains/sites you have (e.g. 10, 50, 200+) and whether they're client sites or your own portfolio, I can narrow this down to the 2–3 best setups and what each would cost.

For a portfolio of sites (especially if you manage sites for clients), you probably want a hosting billing automation platform rather than just a domain registrar dashboard. The right tool should centralize:

• Domain registrations and renewals
• Hosting subscriptions
• SSL renewals
• Client billing/invoices
• Recurring payments
• Expiration reminders
• Service inventory (which site uses which host/domain)
• Client portals and support tickets
• Accounting exports

The main platforms worth evaluating:

1. whmcs.com — best overall for hosting/domain automation

Best fit: agencies, hosting resellers, MSPs, anyone managing many domains and hosting accounts.

Strengths:

• Mature domain registrar integrations
• Automated renewals and invoice generation
• Recurring billing and payment collection
• Works with hosting panels like cPanel/Plesk
• Large ecosystem of add-ons and integrations
• Can act as a client-facing portal if you resell hosting WHMCS WHMCS

Potential downsides:

• More geared toward running a hosting business than a simple internal asset tracker
• Costs can increase as your client/service volume grows Fluent-Themes

I would pick this if: you sell hosting packages, maintenance plans, or recurring website services.

2. blesta.com — best lean alternative

Best fit: smaller agencies that want control without WHMCS complexity.

Strengths:

• Billing, client management, provisioning, and support in one system
• Self-hosted
• Strong API/customization options
• Good for agencies managing recurring retainers and hosting fees Blesta

Potential downsides:

• Smaller ecosystem than WHMCS
• You may need more custom setup depending on registrars and workflows Fluent-Themes

I would pick this if: you have dozens or hundreds of sites but aren't trying to become a full hosting company.

3. hostbillapp.com — best for complex operations

Best fit: larger MSPs, infrastructure providers, or companies with complicated billing rules.

Strengths:

• Deep automation
• Strong infrastructure/cloud billing capabilities
• Broad integration catalog HostBill

Potential downsides:

• More setup effort
• Usually overkill for a normal web agency portfolio

4. Registrar + hosting vendor dashboards (simpler approach)

If you are not reselling hosting and only need internal management, consider combining:

• A domain registrar account with bulk management
• A hosting provider with reseller/multi-account tools
• A billing/CRM system such as: - stripe.com
• chargebee.com
• hellobonsai.com (agency-oriented)

This is often cleaner if your sites are your own properties rather than client services.

My recommendation by portfolio size

For a web design/development agency managing a portfolio of client sites, I would usually start with Blesta or WHMCS, connect your registrar(s), hosting provider(s), and Stripe, then make every domain/hosting renewal a recurring service item.

A few questions would change the recommendation:

1. Are these your own sites or client sites you manage?
2. Roughly how many domains/sites (20, 100, 1,000+)?
3. Do you want to resell hosting, or just track and bill maintenance/renewals?

If your goal is one place to manage a portfolio of domains + hosting + renewals + billing, I’d look at these in roughly this order:

1. whmcs.com — best overall for serious portfolio management

This is probably the closest match to what you're describing.

• Centralizes domains, hosting services, invoices, recurring billing, payments, and renewals.
• Connects to major domain registrars and hosting platforms.
• Can automatically provision/suspend hosting based on billing status.
• Supports bundling domains with hosting plans, configurable add-ons, discounts, and different billing cycles.
• Has automated domain renewal/invoicing and a client portal.
• Works with cPanel, Plesk, DirectAdmin, and many registrars. WHMCS WHMCS
• Current advertised pricing starts at $34.95/month. WHMCS

The important distinction is that WHMCS is primarily the billing/orchestration layer, rather than the actual hosting provider. You can pair it with your preferred hosting infrastructure and registrar.

I'd choose this if you have dozens/hundreds of sites or expect to grow into client billing.

2. cloudflare.com — best if these are mostly your own sites

If you don't need to resell hosting to clients, Cloudflare is considerably simpler.

Cloudflare Registrar lets you consolidate domains into one account, with domains available at registry/ICANN cost rather than a registrar markup. It supports automatic renewal and centralized domain management. Cloudflare Cloudflare Docs

You also get DNS, CDN, SSL, and other infrastructure in the same ecosystem.

The downside is that Cloudflare isn't really a WHMCS-style portfolio billing system. For example, Registrar domains aren't treated as normal subscriptions in the billing interface, and Cloudflare's invoices can be organized per domain/account rather than as a sophisticated portfolio of services. Cloudflare Docs Cloudflare Docs

I'd choose this if you mainly want to eliminate registrar sprawl and have one Cloudflare account/payment method.

3. plesk.com + WHMCS — good managed-server setup

If you're running your own VPS/server and want a GUI for managing lots of websites, Plesk + WHMCS is a particularly good combination.

Plesk handles the actual hosting/site administration, while WHMCS handles the commercial side. Plesk explicitly supports integration with WHMCS and several other billing platforms. Plesk

WHMCS can also bill based on hosting usage and add that usage to renewal invoices when integrated with Plesk. WHMCS Documentation

What I'd do for a portfolio

If these are your own sites, rather than sites you're selling hosting to clients, I'd keep it simpler:

Cloudflare Registrar → domains/DNS
One hosting provider → all hosting
One business card/payment method → recurring infrastructure charges
Accounting system → actual financial records

If you're charging clients for hosting/maintenance, I'd instead build around:

WHMCS → master billing/service database
↓
Domain registrar(s)
Hosting provider / cPanel / Plesk
Stripe/payment processor

That gives you much better control over things like:

Client A → example.com → hosting $30/mo → domain $18/yr → maintenance $75/mo → renew automatically

rather than trying to reconcile a pile of registrar and hosting accounts manually.

One important question

If you tell me roughly how many domains/sites you have (e.g. 10, 50, 200+) and whether they're all yours or belong to clients, I can narrow this down to 2–3 specific setups and compare their actual monthly cost, billing controls, domain renewal handling, and hosting options.

Yes. If you’re managing a portfolio of sites and want domains, hosting, renewals, invoices, and client billing in one place, I’d look first at WHMCS.

WHMCS official site

My shortlist

Why I'd lean WHMCS

WHMCS is specifically designed to make domains + hosting + recurring billing operate as one system. It can:

• Track every domain and its renewal date.
• Automatically generate renewal invoices.
• Collect payment and trigger the domain renewal through the registrar.
• Handle recurring hosting subscriptions separately from annual domain billing.
• Send renewal/overdue reminders.
• Support Stripe, PayPal and other payment gateways.
• Manage hosting provisioning through cPanel, Plesk, DirectAdmin, etc.
• Bundle domains with hosting packages.
• Give you a client portal where customers can see domains, hosting, invoices and payments. www.whmcs.com

Importantly, domain and hosting don't have to share the same billing cycle. For example, you can have $30/month hosting + $20/year domain, while WHMCS handles both as related services. www.whmcs.comdocs.whmcs.com

It also supports multiple registrars, so you don't necessarily have to move all your existing domains to a single registrar just to centralize billing. www.whmcs.com

If these are your own sites rather than client sites

There's an important distinction.

If you have, say, 30–100 sites that you personally own/manage, and your goal is simply:

"I want one dashboard that tells me what domains/hosting I have, when everything renews, and lets me pay centrally."

Then WHMCS may actually be more machinery than you need. It's built around running a hosting/service business and billing customers.

If instead you have:

"I manage sites for 20 clients and want to invoice them for hosting, domains, maintenance, SSL, etc."

then WHMCS is almost exactly the use case. Its billing engine supports recurring products, automated invoicing, payment collection, taxes, proration, late fees and domain renewals. www.whmcs.comsupport.plesk.com

Plesk itself isn't really the answer for the billing side; its own current documentation says billing isn't shipped with Plesk and lists WHMCS, Blesta, HostBill and others as billing integrations. support.plesk.com

My recommendation:

• Agency / client portfolio → WHMCS
• Hosting reseller → WHMCS
• Your own portfolio of sites → potentially a simpler domain/hosting management setup
• WordPress-only agency → worth comparing WPMU DEV before committing

If you tell me roughly how many domains/sites you have, whether they're yours or client-owned, and whether clients pay you for hosting, I can narrow this down to the 2–3 best setups and explain exactly how I'd structure the billing/renewals.

Yes. For a portfolio of sites, I’d look at hosting-billing platforms rather than a generic accounting system. The important distinction is that they can centralize domains, hosting, renewals, recurring invoices, payment collection, and provisioning.

My shortlist

What I'd pick for your use case

If you're talking about your own portfolio of, say, 10–100+ websites, rather than operating a public hosting company, I'd lean toward Blesta.

Its multi-company capability is particularly relevant: one installation can manage multiple companies/brands with separate domains, branding, settings and client bases. www.blesta.com

If instead you want something that feels like the industry-standard hosting control center, go with WHMCS. It can manage clients, services, domains and invoices in one system and currently advertises integrations with 100+ domain registrars and 70+ payment gateways. www.whmcs.comwww.whmcs.com

The architecture I'd aim for is:

Registrar(s) → billing platform → hosting providers/control panels → payment processor

That gives you one place to see:

• Domain renewal dates
• Hosting renewal dates
• SSL/add-on renewals
• Recurring invoices
• Failed payments
• Auto-renewal status
• Which site/client each expense belongs to
• Profitability by site/client
• Renewal reminders and automated payment collection

One important consideration: don't necessarily move all domains and hosting to the same vendor just to get one bill. A billing platform such as WHMCS or Blesta can sit above multiple registrars/hosting providers and give you the centralized operational layer.

If you tell me roughly how many domains/sites you have, whether they're yours or client sites, and whether you want one consolidated credit-card charge or just one dashboard, I can narrow this down to the best 2–3 setups and explain the exact architecture I'd use.

If you're managing a portfolio of sites and want one place to control domains, hosting, invoices, renewals, and payment collection, I’d look at WHMCS first.

Best fit: WHMCS

WHMCS is essentially a billing/operations layer designed specifically around domains + hosting. It can:

• Keep domains, hosting accounts, SSL, email, etc. under one customer/service record.
• Generate recurring invoices and collect payments automatically.
• Handle domain renewal invoicing and automatic registrar renewals.
• Send configurable renewal/overdue reminders.
• Support different billing cycles, including monthly hosting + annual domains.
• Integrate with domain registrars and hosting control panels such as cPanel and Plesk.
• Give you a client portal where customers can see and manage their services. www.whmcs.com

It's particularly good if you're reselling hosting to clients, rather than merely wanting a dashboard for your own websites.

A stack I'd consider

WHMCS + domain registrar + hosting provider

For example:

WHMCS → billing, clients, invoices, renewals
OpenSRS → domain registration/renewals
cPanel/Plesk hosting → actual website hosting

OpenSRS explicitly integrates with WHMCS and other hosting-billing platforms, and lets you set retail domain pricing/markup. opensrs.com

That gives you a fairly clean separation between the billing brain and the underlying providers.

If these are your own sites rather than client sites

There's an important distinction.

If you have, say, 30–100 websites that your company owns, and your goal is:

"Show me every domain/hosting subscription, renewal date, cost, payment method, and let me centrally pay/manage everything."

Then WHMCS may actually be overkill. It's designed around selling/provisioning services to customers.

I'd instead look at a domain registrar with portfolio management + consolidated billing, paired with a hosting platform that lets you manage multiple sites under one account.

If you're selling the sites/hosting to clients, however, WHMCS becomes much more compelling because it can turn the underlying domain/hosting costs into recurring client invoices and automate the whole lifecycle. www.whmcs.com

My shortlist

The key question is whether these are sites you own or sites you're managing/billing clients for. If you tell me roughly how many domains/sites you have, whether they're WordPress, and whether clients pay you for hosting, I can narrow this down to 2–3 specific setups and compare their costs and billing/renewal controls.

If your goal is one operational system for a portfolio of sites—domains + hosting + renewals + client billing, I’d look at WHMCS first.

My shortlist

WHMCS is probably the closest match to what you're describing. It combines customer/service records, recurring invoices, payment collection, hosting provisioning, and domain management. It integrates with 100+ domain registrars and supports automatic domain renewals. www.whmcs.com

A particularly useful feature for a portfolio is that you can treat domains and hosting as separate recurring services while still bundling them together commercially. For example:

Client A → example.com ($20/year) + managed hosting ($30/month) + maintenance ($50/month)

WHMCS can automatically generate invoices, send renewal reminders, collect payment, and—once paid—trigger the domain registrar renewal. You can also configure grace periods, late fees, renewal timing, and auto-renew behavior. docs.whmcs.com

It also supports product bundles, so you could sell something like "Managed Website" that contains hosting, domain, SSL, backups, maintenance, etc. www.whmcs.com

When I'd choose Blesta instead

Blesta is worth serious consideration if you're primarily an agency managing your own portfolio rather than trying to build a full hosting/reseller business. It has recurring invoicing, automatic payments, provisioning, 40+ provisioning modules, and 10+ included domain registrar integrations. www.blesta.com

Its Domain Manager centrally handles domain registration, renewal, provisioning, pricing and packages. docs.blesta.com

One important distinction

If by "centralize" you mean you personally have 50–500 domains/sites and simply want one dashboard to pay for everything, rather than billing clients for hosting/domain services, I'd consider a different architecture.

In that case I'd use:

Domain registrar/reseller account → hosting infrastructure → lightweight billing/accounting system

rather than deploying WHMCS just to manage your own renewals.

If you tell me roughly how many domains/sites you have (e.g. 20, 100, 500), whether you're billing clients for them, and where they're hosted now (Cloudflare, GoDaddy, SiteGround, AWS, cPanel, etc.), I can narrow this down to the best 2–3 setups and explain exactly how I'd structure the billing.

Yes. If the goal is one place to manage domains, hosting, invoices, renewals, and client/site billing, there are a few good approaches. The best choice depends on whether these are your own sites or you're managing sites for clients.

My shortlist

1. WHMCS — best if billing control is the priority

This is the one I'd look at first if you're building an agency/site portfolio operation.

WHMCS can centralize:

• Domains and domain renewals
• Hosting subscriptions
• Recurring invoices
• Automatic payment collection
• Renewal reminders
• Automatic domain renewal after payment
• Hosting provisioning/suspension
• Client accounts and service history
• Add-ons and bundled products
• Multiple payment gateways
• Reporting

It integrates with 100+ domain registrars, 70+ payment gateways, and hosting systems such as cPanel, Plesk and DirectAdmin. www.whmcs.com

The particularly useful feature for your use case is that you can create something like:

Website Package — $X/month
Includes hosting + domain + SSL + backups + maintenance

and have the underlying domain/hosting services tied to that customer's billing lifecycle.

If you expect to eventually manage 50–500+ domains/sites, I'd lean strongly toward WHMCS.

2. WPMU DEV — potentially the easiest choice for WordPress

If your portfolio is predominantly WordPress, this is arguably more attractive than assembling WHMCS + hosting + management tools.

WPMU DEV's Hub combines site management, hosting, domains, client billing, support and white-label functionality. Its reseller system lets you create your own hosting/domain products and sell them through a client portal. wpmudev.com

It specifically supports:

• Multiple WordPress sites in one dashboard
• Hosting
• Domains
• Client billing
• White-label client portal
• Hosting/domain packages
• Recurring billing
• Site maintenance
• Backups and updates

So if you're thinking:

"I have 30 WordPress sites and want one dashboard where I know what every site costs, when every domain renews, and what each client is paying me."

WPMU DEV is probably the simplest solution.

3. Plesk — great infrastructure layer

Plesk is more about hosting management than being your central financial system.

It does an excellent job organizing customers, domains, subscriptions and hosting plans, including multiple subscriptions under a customer account. docs.plesk.com

I'd think of it as:

WHMCS = business/billing layer
Plesk = hosting/infrastructure layer

rather than choosing Plesk by itself for your billing requirements.

What I'd choose

If this is your own portfolio of sites, rather than a customer-facing hosting business:

Mostly WordPress → WPMU DEV

Mixed WordPress/non-WordPress → WHMCS + a good hosting platform

You want to eventually resell hosting/domains to clients → WHMCS

The key distinction is that WHMCS is designed around the concept of turning domains + hosting + services into billable products, whereas ordinary hosting dashboards are primarily designed around administering servers.

One thing I'd strongly recommend: don't optimize only for "one dashboard." Look for a system that lets you associate every recurring expense and revenue item with a site/customer, including domain renewal date, hosting renewal, SSL, backups, licenses, and maintenance. That's what makes portfolio billing manageable once you have dozens of sites.

If you tell me roughly how many sites/domains you have (e.g. 10, 50, 200), whether they're WordPress, and whether they're your sites or client sites, I can narrow this down to the 2–3 best setups and what the monthly cost/architecture would look like.

If your goal is one place to manage domains, hosting, renewals, invoices, and payment collection across a portfolio of sites, I’d look primarily at WHMCS and Blesta.

My pick: WHMCS

WHMCS is probably the closest match if you want a mature, hosting-oriented “control center.”

It can handle:

• Domain registration, transfers and renewals
• Hosting provisioning through cPanel, Plesk, DirectAdmin, etc.
• Recurring invoices and automatic payment collection
• Renewal reminders and automated renewal workflows
• Product/service bundles — e.g. Domain + Hosting + SSL
• Customer/client portals
• Automatic suspension for unpaid services
• Multiple domain registrars and 100+ registrar integrations
• Multiple payment gateways
• Taxes, coupons, prorating and reporting www.whmcs.com

The particularly useful part for a portfolio is that WHMCS treats domains and hosting as related billable services, rather than making you maintain a spreadsheet of renewal dates. It also supports product bundles. www.whmcs.com

Strong alternative: Blesta

Blesta is worth serious consideration if you want something somewhat more lightweight/developer-friendly.

It supports:

• Domain registration/renewal/transfer management
• Recurring billing
• Automatic payment processing
• Hosting provisioning
• cPanel/Plesk/DirectAdmin integrations
• 10+ included domain registrar integrations
• Multi-currency
• Proration
• Multiple payment gateways
• Client portals and support
• REST API/webhooks www.blesta.com

Blesta's current pricing also starts considerably lower than WHMCS, with monthly plans from $17.95/month and unlimited clients/staff. www.blesta.com

How I'd choose

One important distinction: WHMCS/Blesta are billing/automation layers, not necessarily your actual registrar or hosting provider. You'd typically connect them to a registrar and hosting infrastructure. For example:

Registrar → Domains
Hosting provider/cPanel/Plesk → Websites
WHMCS/Blesta → billing, renewals, provisioning, client records

For a portfolio of, say, 20–200 sites, I'd probably build the setup around WHMCS + a reseller domain registrar + one or more hosting providers, with WHMCS as the system of record.

If you tell me roughly how many domains/sites you have, whether they're all yours or client sites, and whether you want to resell hosting, I can narrow this down to a specific architecture and a few registrar/hosting combinations.

Yes. If your goal is one control plane for a portfolio of sites—domains, hosting, renewals, recurring billing, invoices, and payment collection—I’d look at WHMCS first, with Blesta as the strongest alternative.

My shortlist

1. WHMCS — probably what you're looking for

WHMCS is specifically designed to put domains + hosting + billing + renewals under one system. It can automate recurring invoices, payment collection, renewal reminders, domain registration/renewal, hosting provisioning, suspensions for nonpayment, and customer/service management. It also supports product bundles, which is useful if you want something like:

Website A → domain + hosting + maintenance → $X/month or $X/year

WHMCS integrates with 100+ domain registrars, 70+ payment gateways, and hosting platforms such as cPanel, Plesk, and DirectAdmin. www.whmcs.com

The particularly useful part for a portfolio is that domains and hosting become services attached to a customer, rather than you maintaining a spreadsheet of expiration dates and manually paying different vendors.

WHMCS hosting & domain automation

2. Blesta — I'd seriously consider this if you're an agency

Blesta does essentially the same core job: recurring billing, invoices, automatic payments, domain management, hosting provisioning, client accounts, and integrations with cPanel/Plesk/DirectAdmin and domain registrars. It also supports multi-company configurations, APIs, custom reporting, and migration from WHMCS. www.blesta.com

I'd lean Blesta over WHMCS if you want something that feels more like an internal billing/operations system rather than building a full-fledged hosting reseller storefront.

Blesta features

The architecture I'd use

For a portfolio of, say, 20–200 websites, I wouldn't necessarily look for one company that supplies everything.

I'd separate the system into:

Billing/control plane
→ WHMCS or Blesta

Domain registrar
→ OpenSRS, Openprovider, CentralNic, etc.

Hosting
→ Your preferred VPS/cloud/shared hosting provider

Payments
→ Stripe/ACH/etc.

The billing platform connects everything.

For example:

Client → WHMCS → Stripe
      ↳ domain registrar
      ↳ hosting provider
      ↳ SSL
      ↳ maintenance/management services

OpenSRS specifically supports bundling domains into packages and integrates with WHMCS, HostBill and other billing systems. opensrs.com

One important distinction

If these are your own sites, rather than sites you're reselling to clients, you may not actually need WHMCS/Blesta.

If what you really mean is:

"I own 50 websites and want one dashboard/card/account where I can see every domain, hosting subscription, renewal date, cost, and automatically pay everything."

Then I'd approach this differently. WHMCS is somewhat overkill because it's designed around selling and billing services to customers.

If, however, you're managing websites for clients and billing them for hosting/domains/maintenance, then WHMCS is probably the right category of software.

If you tell me roughly how many domains/sites you have (e.g. 10, 50, 200+) and whether you're billing clients or just managing your own portfolio, I can narrow this down to the best 2–3 setups and what the monthly cost would look like.

Yes. If your goal is one place to manage domains, hosting, renewals, recurring billing, invoices, and customer/site-level services, I’d look primarily at WHMCS rather than a traditional accounting platform.

My shortlist

My pick: WHMCS

For a portfolio of sites, WHMCS is particularly well suited because it treats domains, hosting accounts, SSL, add-ons, and other services as billable products rather than making you manage them separately.

It supports:

• recurring invoices and automatic payment collection
• automatic renewal reminders
• domain registration, transfers and renewals
• integration with 100+ domain registrars
• hosting provisioning through cPanel, Plesk, DirectAdmin, etc.
• product bundles and add-ons
• proration when changing plans
• multiple billing cycles
• Stripe/PayPal and other payment gateways
• customer/service-level billing history
• automatic suspension/reactivation for delinquent accounts www.whmcs.com

The product-bundle capability is especially relevant to what you're describing. You could, for example, structure a site as:

Website A
├── Domain — $20/year
├── Managed hosting — $30/month
├── SSL — included
├── Maintenance — $100/month
└── Backups — $15/month

…and have WHMCS generate/collect the appropriate recurring charges and manage the underlying services. www.whmcs.com

An interesting alternative: OpenSRS

If you don't need a full hosting-business billing system and mainly want domains centralized, OpenSRS is worth considering. Its reseller platform lets you set your own domain margins, automate renewals, and connect to billing systems such as WHMCS, HostBill and ClientExec. opensrs.com

OpenSRS also now has managed reseller hosting on AWS, with site-level isolation and per-site pricing, which could make an interesting combination for a portfolio where you want the infrastructure and domains under one reseller relationship. opensrs.com

What I'd choose for your use case

If you're managing 10–100+ sites for clients or multiple businesses, I'd lean:

WHMCS + domain reseller + hosting provider

rather than trying to find one giant hosting company that does everything.

That gives you a central layer:

WHMCS
→ customers/sites
→ invoices & recurring payments
→ renewal dates
→ domain registrar
→ hosting provider
→ SSL/backups/add-ons

The key advantage is that you aren't locked into one hosting provider. WHMCS can provision/manage services across different infrastructure providers while keeping the billing relationship centralized. www.whmcs.com

If you're managing your own sites rather than selling hosting to clients, though, I'd use a somewhat different stack—WHMCS can be overkill. In that case, tell me roughly how many domains/sites you have (e.g. 20, 100, 500) and whether they're your sites or client sites, and I can narrow this down to 2–3 good setups.

Yes. If your goal is one place to manage domains + hosting + renewals + client billing, I’d look at a hosting-management/billing platform rather than a normal hosting provider.

My top pick: WHMCS + a hosting control panel

WHMCS is probably the strongest fit if this is a serious portfolio or agency operation.

It can centralize:

• Domain registrations, transfers and renewals
• Hosting subscriptions and renewals
• Recurring invoices and automatic payment collection
• Client accounts and billing history
• Renewal reminders
• Taxes, multiple currencies and payment gateways
• Hosting provisioning/deprovisioning
• Add-ons such as SSL, backups, email, maintenance, etc.
• Different pricing/billing rules per client or service

WHMCS integrates with 100+ domain registrars and leading hosting panels such as cPanel and Plesk. Its domain system can synchronize expiration dates and automatically trigger registrar renewals after payment. www.whmcs.com

A particularly good architecture would be:

WHMCS → billing/client management
Plesk or cPanel → actual hosting management
Registrar → domain registration

For example, WHMCS + Plesk has official integration for provisioning, account management, domains, upgrades, billing, suspensions, etc. docs.whmcs.com

If these are your own sites, not client sites

Then I wouldn't necessarily deploy the full WHMCS stack.

A simpler arrangement could be:

Cloudflare Registrar + your preferred hosting provider + centralized accounting

Cloudflare Registrar is particularly attractive for a portfolio because it supports domain consolidation and charges the registry's registration/renewal price without registrar markup. It also has automatic renewal and consolidated charging when multiple domains renew on the same date. www.cloudflare.com

The catch: Cloudflare's Registrar billing isn't really designed as a sophisticated subscription billing system—domains aren't treated as subscriptions in its billing interface. developers.cloudflare.com

What I'd choose

The key distinction: if by "billing controls" you mean "I want every domain, hosting plan, SSL, backup and maintenance service to appear as line items on a client's recurring invoice, with automated renewal and payment collection," then WHMCS is much closer to what you're describing. It was specifically built around that model. www.whmcs.com

If you tell me roughly how many sites you have (e.g. 10, 50, 200), whether they're yours or client sites, and whether you want to resell hosting, I can narrow this down to 2–3 concrete setups and compare their costs/workflow.

Yes. If your goal is one place to manage domains, hosting, recurring invoices, renewals, and client billing, I’d shortlist these:

My recommendation: WHMCS

For a portfolio where you're effectively selling “website hosting + domain + maintenance” as a recurring package, WHMCS is probably the most flexible choice.

It can:

• Put domain registration/renewal and hosting on the same client account
• Generate recurring invoices automatically
• Handle different billing cycles — e.g. domain annually + hosting monthly
• Automatically send renewal reminders
• Trigger domain renewal through the registrar after payment
• Bundle domains with hosting products
• Apply your own pricing/markup
• Handle payment collection and failed-payment workflows
• Support hosting provisioning through systems such as cPanel/Plesk
• Give clients a portal for invoices, domains and services docs.whmcs.com

That's particularly useful if your model is something like:

Client A → example.com → $20/mo hosting + $25/yr domain + $75/mo maintenance

You can make those separate billable services while presenting them together as a single client relationship/invoice.

WHMCS currently starts at $34.95/month for up to 250 active clients on its Plus plan, with higher tiers for larger client bases. www.whmcs.com

If these are mostly WordPress sites: WPMU DEV is worth serious consideration

WPMU DEV's hosting/reseller platform is much more turnkey.

It combines WordPress management + hosting + domains + client portal + billing + reseller functionality. Its billing system connects to Stripe, supports recurring products/subscriptions, and lets you associate services and invoices with particular websites/domains. wpmudev.com

It also supports creating your own hosting/domain packages and reselling them under your own branding. wpmudev.com

So if you're managing, say, 20–100 WordPress sites, I'd seriously consider WPMU DEV because it eliminates a lot of separate infrastructure.

The distinction I'd use

Choose WHMCS if:

• You want maximum control over billing
• You have multiple hosting providers/servers
• You want to choose your own domain registrar
• You may eventually resell hosting
• You have non-WordPress sites
• You need sophisticated provisioning, invoicing and automation

Choose WPMU DEV if:

• 80–100% of the portfolio is WordPress
• You want an all-in-one managed environment
• You want to minimize server/hosting administration
• Your business is more “website management agency” than “hosting company”

One important architectural point: don't necessarily move all your domains to the same company that hosts the websites. A billing/provisioning layer such as WHMCS can sit above your registrar and hosting infrastructure. That gives you much more freedom to change hosts later without disrupting your billing system.

If you tell me roughly how many sites you manage (e.g. 10, 50, 200), whether they're WordPress, and whether you're billing clients or just managing your own portfolio, I can narrow this down to the best 2–3 setups and explain exactly how I'd structure the domain/hosting/maintenance billing.

Yes. If your goal is one control center for domains, hosting, renewals, invoices, payment collection, and client/site billing, I’d look at a billing/automation platform rather than just a hosting provider.

My top pick: WHMCS + a domain registrar/reseller

WHMCS is probably the closest match to what you’re describing. It is designed specifically to centralize hosting and domain operations.

It can handle:

• Domains — registration, transfers, renewals, nameservers, WHOIS/DNS management
• Hosting — provision/suspend hosting accounts and synchronize them with hosting servers
• Recurring billing — invoices, payment gateways, reminders, overdue accounts
• Automatic renewals — invoice customers and trigger registrar renewals after payment
• Bundles — e.g. Website Hosting + Domain + SSL as one package
• Client portal — customers can see all their domains/services/invoices in one place
• Multiple registrars and hosting providers — you're not locked into one infrastructure vendor
• Reporting — revenue and billing activity across the portfolio www.whmcs.com

The important distinction is that WHMCS is the billing/management layer, while you connect it to a domain registrar and hosting infrastructure.

A particularly good combination

WHMCS + OpenSRS + your preferred hosting

OpenSRS is worth considering as the domain layer. It offers wholesale domain registration, automatic renewals, bulk management, pricing controls, and integrates directly with WHMCS. It supports 700+ TLDs. opensrs.com

That gives you roughly:

WHMCS
→ customer/site records
→ billing & invoices
→ subscriptions
→ bundles
→ payment collection
→ renewal notices

OpenSRS
→ domains
→ registrations/transfers
→ DNS
→ domain renewals

Hosting provider
→ servers
→ WordPress/cPanel/etc.
→ backups
→ actual website infrastructure

This is a much more flexible architecture than putting every site at one registrar/host.

If this is your own portfolio, not clients

There's an important wrinkle.

If you're managing, say, 30–200 sites that you personally own/manage, and you don't need customers logging into a portal, WHMCS can actually be more machinery than you need.

In that case I'd consider a simpler setup where:

one account → all domains → all hosting → consolidated payment method → centralized renewal calendar

rather than implementing a full reseller billing system.

If, however, you bill clients monthly/annually for hosting, domains, maintenance, etc., I'd strongly favor WHMCS.

Other options

OpenSRS's own Storefront is interesting if you primarily want domains + automated payments + customer self-service without building a full WHMCS stack. It supports global/custom TLD pricing, auto-renewals, card/Apple Pay/Google Pay, branded renewal messages, and a client portal. opensrs.com

Namecheap is another relatively turnkey route: its reseller hosting supports WHM/cPanel and explicitly integrates with WHMCS for billing and domain registration. www.namecheap.com

What I'd choose

For a professional web-agency portfolio, I'd lean:

WHMCS + OpenSRS + separate managed hosting

That gives you the most control and makes it easier to move hosting providers without rebuilding your billing system.

If you tell me roughly how many sites/domains you have (e.g. 20, 100, 500) and whether they're your sites or client sites, I can narrow this down to 2–3 concrete setups and compare monthly cost, renewal automation, billing controls, and ease of migration.

Yes. If your goal is one place to manage domains, hosting, renewals, invoices, and payment collection across a portfolio, I’d look primarily at WHMCS and Blesta.

My first choice: WHMCS

WHMCS is probably the closest match to what you described.

It can centralize:

• Domain registrations and renewals across supported registrars
• Hosting services through cPanel, Plesk, DirectAdmin, etc.
• Recurring billing and automatic payment collection
• Renewal notices and overdue reminders
• Domain/hosting bundles and add-ons
• Client portals and service-level management
• Automatic provisioning, suspension, and renewal
• Multiple payment gateways, currencies, taxes, coupons, etc. www.whmcs.com

Importantly, WHMCS can treat domains and hosting as separate services while still presenting them together to a customer. You can also bundle a domain with a hosting package. www.whmcs.com

For renewals specifically, it can generate domain-renewal invoices ahead of expiration and, after payment, trigger the renewal through the registrar API. You can configure renewal notices and grace-period/late-fee behavior as well. docs.whmcs.com

Strong alternative: Blesta

Blesta is worth considering if you want something somewhat more lightweight/developer-friendly.

It provides recurring invoicing, automatic payments, provisioning, client management, hosting integrations, and a domain manager. Its domain manager handles registration, renewal, provisioning, and pricing/packages. blesta.com

Blesta currently advertises 30+ payment gateways, 40+ provisioning modules, and integrations for cPanel, Plesk, DirectAdmin, VPS/cloud platforms, and multiple domain registrars. www.blesta.com

How I'd choose

One important distinction: neither is necessarily the actual hosting provider. Think of WHMCS/Blesta as the billing + service orchestration layer. You can have domains at one or more registrars and hosting on your own VPS/cloud/cPanel infrastructure, while the billing system ties everything together.

If this is for, say, 10–100+ websites that you own/manage yourself, rather than selling hosting to customers, I'd actually evaluate a slightly different setup. In that case, you may want centralized portfolio renewal management without the overhead of running a mini hosting company. If you tell me roughly how many domains/sites you have and whether they're client-owned or all yours, I can narrow it down to the best 2–3 setups.
