For 25 client websites, you’re probably not looking for a traditional “hosting reseller” panel alone — you need a stack that gives each client:

• separate billing/invoices
• their own client portal
• automatic renewals
• hosting account provisioning
• domain/email/service tracking
• room to grow to 100+ sites

My shortlist would be:

My recommendation for your situation

For 25 managed client websites, I would pick:

Option A — Agency-friendly setup (my first choice)

• Blesta
• A managed VPS or reseller hosting account
• cPanel/WHM or Plesk for account separation
• Stripe/PayPal for payments
• Automated monthly invoices

Why:

• Each client gets their own billing record.
• You can charge $X/month per website.
• You can bundle hosting, maintenance, backups, SSL, updates, etc.
• You are not locked into a hosting-company workflow.

Blesta specifically supports billing, automation, provisioning, support, and client management features designed for hosting providers and agencies. Blesta

Option B — If you want to become a hosting company

Use:

• WHMCS
• cPanel/WHM reseller or VPS
• domain reseller account
• automated provisioning

WHMCS is still the common choice when you need the widest compatibility with hosting-related services. KnownHost - Managed Hosting Specialists

Architecture I’d use

Your Agency
│
├── Billing system (Blesta or WHMCS)
│
├── Hosting server
│   ├── Client A website account
│   ├── Client B website account
│   ├── Client C website account
│   └── ...
│
├── Backups
├── Monitoring
└── Support portal

Avoid putting all 25 sites into one shared WordPress hosting account. Separate accounts make:

• migrations easier
• security better
• billing cleaner
• client handoff possible

A few questions would change the recommendation:

1. Are these WordPress sites?
2. Do clients pay you a monthly maintenance fee, or are you only reselling hosting?
3. Do you want clients to see a white-label portal and manage their own services?
4. Are you currently on cPanel, Plesk, Cloudways, AWS, or something else?

For a web agency with 25 sites, the answer is usually Blesta + managed VPS/reseller hosting, unless you specifically want to operate like a hosting provider.

For a web agency with 25 sites, the answer is usually Blesta + managed VPS/reseller hosting, unless you specifically want to operate like a hosting provider.

For 25 client websites where each client needs their own billing/invoice/account, I’d pick WHMCS + a cPanel/WHM reseller or VPS platform.

whmcs.com is particularly well suited because it separates client accounts, services, invoices, payments, and support, rather than treating all 25 sites as one hosting account. WHMCS Documentation WHMCS Documentation

My recommended setup

Hosting: cPanel/WHM
Management/billing: WHMCS
Your structure: one WHMCS client account per customer

This gives you:

• Separate recurring invoices for each client
• Automatic provisioning/suspension when bills are unpaid
• Individual cPanel accounts for each website
• Client self-service portal
• Automatic upgrades/downgrades
• Centralized support tickets
• Ability to charge clients for hosting, domains, SSL, backups, maintenance, etc.
• Room to grow well beyond 25 sites

WHMCS has direct cPanel integration for account creation, suspension/reactivation, usage reporting, package synchronization, and single sign-on. WHMCS WHMCS

One important distinction

If you are the agency and these are your 25 web-design/maintenance clients, I would not create 25 separate reseller accounts.

Instead:

Your business → 1 hosting account/server → 25 separate cPanel accounts → 25 separate WHMCS client accounts

That keeps administration simple while maintaining billing and account isolation.

WHMCS also supports usage-based reseller billing if you eventually want to resell hosting to your clients' clients, including billing by number of cPanel accounts. WHMCS Documentation

What I'd choose at your size

At 25 clients, WHMCS's current Starter tier is exactly 25 active clients at $9.99/month, while Plus supports up to 250 for $34.95/month. WHMCS I'd probably go with Plus if you expect to add clients, because you won't immediately run into the limit.

If you tell me whether the 25 sites are mostly WordPress and whether you want to manage the server yourself or have it fully managed, I can recommend the actual hosting provider/server configuration to pair with WHMCS.

For 25 client websites, where you want each client to have separate billing, invoices, payments, and ideally their own hosting login, I’d pick WHMCS + cPanel/WHM.

My recommendation

Why WHMCS: it can automatically create/manage cPanel accounts, suspend overdue accounts, synchronize accounts, track resource usage, and provide clients with a billing/support portal. www.whmcs.com

It also supports separate client accounts and recurring invoices, so you can have:

Client A → Website A → Hosting → $X/month
Client B → Website B → Hosting → $Y/month
Client C → Website C → Hosting → $Z/month

without manually creating invoices every month. www.whmcs.com

One important distinction

If by "reseller hosting" you mean you buy one large reseller account and put all 25 websites underneath it, I'd structure it as:

Your agency
→ WHMCS
→ reseller hosting account / WHM
→ 25 individual cPanel accounts
→ one client per cPanel account

WHMCS can even handle reseller products with per-account/sub-account billing, tiered pricing, and usage-based charges. docs.whmcs.com

WHMCS vs. Blesta

I'd choose WHMCS if you want the most mature ecosystem and expect the hosting operation to grow. Its current self-hosted Plus plan supports up to 250 active clients at $34.95/month, so 25 clients is comfortably within that tier. www.whmcs.com

Blesta is the alternative I'd seriously consider. Its current version supports cPanel, Plesk, DirectAdmin and 40+ provisioning modules, recurring billing, 30+ payment gateways, support, APIs, and multi-company functionality. www.blesta.com

What I'd do in your situation

cPanel/WHM + WHMCS if your primary goal is:

• 25 separate clients
• automatic recurring billing
• separate invoices/payment methods
• automated provisioning
• automatic suspension for nonpayment
• client portal
• support tickets
• ability to add domains/SSL/maintenance as separate billable services
• room to grow to 100+ sites

One caveat: WHMCS is billing/automation software, not the actual hosting server. You'll still need the underlying reseller hosting or VPS/server.

If you tell me roughly what you currently pay for hosting per month and what you charge each client, I can also lay out the cheapest architecture for 25 sites (reseller account vs VPS + cPanel vs managed WordPress hosting) and estimate your margin.

For 25 client websites, I’d pick WHMCS if your goal is a professional reseller setup where each client gets their own login, invoices, payment method, hosting service, and billing history.

My recommendation

Why WHMCS: it integrates tightly with cPanel/WHM and can automate the entire customer lifecycle—creating accounts, suspending overdue accounts, provisioning services, handling invoices, and providing a client portal. It also supports usage-based billing for individual accounts under a reseller, which could become useful if you eventually charge clients differently based on resources. docs.whmcs.com

The current self-hosted WHMCS Plus plan supports up to 250 active clients for $34.95/month, so 25 clients is comfortably within the entry tier. www.whmcs.com

When I'd choose Blesta instead

If you're essentially an agency that happens to resell hosting, rather than trying to become a hosting company, I'd seriously consider Blesta. It has recurring billing, automatic provisioning, client portals, support tickets, cPanel/Plesk/DirectAdmin integrations, and unlimited clients/staff. Its branded monthly license is currently $17.95/month, or you can buy an owned license. www.blesta.com

So for your situation:

Agency + 25 sites + want polished client billing → WHMCS.

Agency + 25 sites + want to minimize software cost → Blesta.

One important distinction: WHMCS/Blesta are the billing/management layer, not the actual hosting server. I'd pair one with a VPS/dedicated server running cPanel/WHM, then give each client their own cPanel account. WHMCS can provision and manage those accounts automatically. docs.whmcs.com

If you tell me what you're paying today for hosting and roughly what you want to charge each of the 25 clients, I can recommend the exact stack (server + cPanel + WHMCS/Blesta) and estimate your monthly margin.

For 25 client websites, I’d pick WHMCS + a reseller/VPS hosting provider that supports cPanel/WHM or DirectAdmin.

WHMCS is particularly well suited if by “separate billing” you mean each client gets their own account, invoices, payment method, hosting service, and client portal.

My recommendation

WHMCS can automatically provision, modify, suspend and terminate hosting accounts, while handling recurring invoices, payment collection, reminders and client self-service. www.whmcs.com

Importantly, WHMCS supports per-account/usage billing for reseller accounts, so you can structure things like a base hosting fee plus charges for additional cPanel accounts if your business model needs that. docs.whmcs.com

What I'd build for your 25 sites

Hosting provider → WHM/cPanel reseller → WHMCS → your 25 clients

Each client gets:

• Their own WHMCS login
• Their own hosting service
• Their own recurring invoice
• Their own credit card/PayPal payment method
• Automatic renewal/payment collection
• Automatic suspension for non-payment
• Their own hosting credentials
• Optional domain registration/renewal
• Support tickets
• A branded client portal

You can then charge, for example:

Client A: $75/mo website management + $20/mo hosting
Client B: $125/mo website management + $20/mo hosting
Client C: $200/mo website management + $30/mo hosting

…and WHMCS handles the recurring billing separately for each customer.

One important distinction

If these 25 sites are your agency's managed websites and you don't actually want clients logging into a hosting panel, I would not necessarily buy a traditional reseller-hosting package.

Instead, I'd consider:

Managed VPS + cPanel/WHM + WHMCS

That gives you much more control and lets you put multiple client accounts on one server while keeping them isolated.

If you're trying to keep costs down, Blesta is the strongest alternative. Its current branded license is $17.95/month with unlimited clients/staff, and it supports cPanel, Plesk and DirectAdmin provisioning. www.blesta.com

Bottom line: I'd choose WHMCS for your situation unless minimizing software cost is the priority. At only 25 clients, you have plenty of room to grow before WHMCS's client limits become relevant; its current self-hosted Plus plan supports up to 250 active clients at $34.95/month. www.whmcs.com

If you tell me what you're currently paying for hosting and roughly what you charge each of the 25 clients, I can recommend the actual hosting stack (provider + VPS/reseller tier + cPanel/DirectAdmin + WHMCS) and estimate your monthly profit.

For 25 client websites, you probably don’t need a full “hosting company” stack, but you do want:

• each client to have their own account
• separate invoices/subscriptions
• automated renewals
• the ability to suspend/reactivate for non-payment
• optional white-label hosting if you resell under your brand
• room to grow to 100–500 sites

My shortlist would be:

teklanhosting.co.uk

My recommendation for your situation

Pick: Blesta + reseller hosting with WHM/cPanel (or Plesk).

Why:

• 25 clients is small enough that you don't need WHMCS's massive ecosystem.
• You can give every client their own hosting package and invoice separately.
• It is cost-effective if you expect to stay an agency rather than become a large hosting provider. Blesta offers unlimited clients on its plans, while WHMCS pricing scales by active client tiers. blesta.com

A typical setup:

Your Agency
   |
   |-- Blesta (billing + client portal)
   |
   |-- Reseller Hosting Account
          |
          |-- Client A website
          |-- Client B website
          |-- Client C website
          ...
          |-- Client Y website

When I would choose WHMCS instead

Choose WHMCS if you plan to:

• sell hosting publicly to strangers
• offer many hosting tiers
• automate domain registrations
• integrate many payment gateways
• grow into hundreds/thousands of customers

It remains the most widely recognized hosting automation platform because of its integrations and marketplace ecosystem. hostbillingpro.com

Hosting provider setup I’d pair with it

For 25 WordPress/business sites, I’d avoid cheap shared reseller plans. Look for:

• NVMe storage
• daily backups
• LiteSpeed or NGINX caching
• staging sites
• free SSL
• white-label nameservers
• cPanel/WHM or Plesk
• ability to create isolated accounts

One thing I would avoid

Do not put all 25 sites under one shared cPanel login. If one site is compromised, everything can be affected. Use separate hosting accounts.

If you tell me:

1. WordPress or mixed platforms?
2. Do clients pay you monthly for hosting/maintenance?
3. Do you want clients to log in themselves?
4. Current host (GoDaddy, SiteGround, Cloudways, etc.)?

…I can suggest a more specific stack.

For 25 client websites, I’d pick WHMCS unless you have a strong reason to minimize software costs.

My recommendation

1. WHMCS — best overall for your use case

WHMCS is purpose-built for hosting companies and agencies. It can:

• Give each client their own account/login
• Generate separate recurring invoices per client
• Automatically collect payments via Stripe/PayPal and other gateways
• Provision/suspend hosting automatically
• Handle upgrades, add-ons, domains, taxes, coupons, etc.
• Give clients their own billing/support portal
• Integrate tightly with cPanel, Plesk, and other hosting platforms www.whmcs.com

For an agency managing 25 sites, this means you can essentially have:

Client A → $X/month → their hosting account → their invoice
Client B → $Y/month → their hosting account → their invoice
Client C → $Z/month → their hosting account → their invoice

without manually managing 25 subscriptions.

WHMCS also supports reseller-specific billing and can track the number of cPanel accounts a reseller creates if you eventually expand into actual hosting reselling. docs.whmcs.com

2. Blesta — best value alternative

Blesta is the one I'd seriously consider if you don't want WHMCS.

It has recurring invoicing, automatic payments, client portals, provisioning, support tickets, cPanel/Plesk/DirectAdmin modules, and even multi-company support. www.blesta.com

For a small web agency, Blesta can be particularly attractive because it's less "hosting-industry heavyweight" while still providing the important automation.

What I'd do in your situation

One important distinction: if by "reseller hosting" you mean you want to buy one reseller hosting package and put all 25 client sites under it, you don't necessarily need to become a hosting company or give clients access to WHMCS. You can use WHMCS/Blesta as your billing layer while the actual hosting comes from a reseller provider.

If you tell me (1) whether the 25 sites are WordPress, (2) whether you want each client to pay you directly, and (3) roughly what you want to spend per month on hosting, I can narrow this down to the best reseller host + billing platform combination for 25 sites.

For 25 client websites, I’d pick Blesta unless you specifically need the larger WHMCS ecosystem.

My recommendation: Blesta

Blesta is a particularly good fit for a web agency/reseller setup because you can:

• Give each client their own account and billing
• Automatically generate recurring invoices and collect payments
• Provision/suspend hosting automatically
• Connect to cPanel, Plesk, or DirectAdmin
• Handle domains, SSL, support tickets, quotes, etc.
• Keep your hosting operation separate from your clients' individual billing
• Start at $17.95/month with unlimited clients on its branded plan, according to current pricing. www.blesta.com

For only 25 sites, that's attractive because you're not paying substantially more as your client count grows.

Blesta vs. WHMCS

WHMCS is the more established hosting-specific choice and has a huge integration ecosystem. It also supports sophisticated usage billing—for example, billing a reseller based on the number of cPanel accounts they create. docs.whmcs.com

WHMCS pricing currently starts at $34.95/month for up to 250 active clients on its self-hosted Plus plan. www.whmcs.com

What I'd do in your situation

If your model is:

You → reseller hosting account/server → 25 individual client websites → each client gets their own invoice

I'd build it like:

Your hosting provider
→ cPanel/WHM or DirectAdmin
→ Blesta
→ Client A
→ Client B
→ Client C
→ ...
→ Client 25

Each client gets their own login, invoice history, payment method, renewal date, hosting service, and support relationship.

One important distinction: if by "separate billing" you mean each client should receive their own independent hosting invoice, both Blesta and WHMCS do that. If you mean 25 completely separate companies/brands with separate accounting and billing identities, Blesta has a particularly interesting advantage: its paid multi-company support can isolate settings and branding within one installation. www.blesta.com

Bottom line: I'd choose Blesta for 25 agency clients. I'd move to WHMCS if you expect to become a substantial hosting reseller, need a specific WHMCS-only integration, or want the broadest possible hosting-industry ecosystem.

If you tell me which reseller host you're considering (e.g. cPanel/WHM, HostGator, Liquid Web, Namecheap, etc.) and whether clients need to log into their own hosting panels, I can recommend the exact setup—including hosting provider + control panel + billing software + domain/SSL automation.

For 25 client websites, I’d pick WHMCS + a reseller-capable hosting panel, unless you have a strong reason to avoid WHMCS.

My recommendation

1. WHMCS — best overall

• Built specifically for hosting billing, provisioning, domains, support, and recurring invoices.
• Supports separate client accounts, so each website/client can have its own login, services, invoices, payment method, etc. docs.whmcs.com
• If you're using cPanel/WHM, WHMCS can automatically provision accounts and even do usage/overage billing. docs.whmcs.com
• Current self-hosted pricing starts at $34.95/month for up to 250 active clients, so 25 websites won't be a problem. www.whmcs.com

WHMCS

2. Blesta — best value alternative

• Particularly attractive if you want something lighter and cheaper.
• Current branded monthly license is $17.95/month with unlimited clients and staff. www.blesta.com
• Supports recurring billing, automatic provisioning, cPanel/Plesk/DirectAdmin, multiple payment gateways, domains, support tickets, and multi-company setups. www.blesta.com

Blesta

3. HostBill — consider if you need more complex automation

• Strong hosting automation and reseller/WHM functionality, but I'd consider it overkill for only 25 sites unless you're building a larger hosting business. hostbillapp.com

HostBill

What I'd build

For your situation:

WHMCS → cPanel/WHM → separate hosting account per client → Stripe/ACH → automatic monthly billing

That gives you:

Client A → website/account → invoice → payment
Client B → website/account → invoice → payment
Client C → website/account → invoice → payment

while you manage everything centrally.

One important distinction: if by "separate billing" you mean each of your 25 clients needs their own independent billing portal/invoices, WHMCS and Blesta both handle that. If you mean 25 completely separate companies/brands with isolated billing, Blesta's multi-company functionality becomes particularly interesting. www.blesta.com

My pick: WHMCS if you want the safest, most established hosting stack; Blesta if minimizing monthly software cost is important.

If you tell me whether you're using cPanel, Plesk, or DirectAdmin, I can recommend the exact reseller-hosting setup and pricing structure I'd use for 25 sites.

For 25 client websites, I’d pick Blesta + cPanel/WHM unless you specifically need the enormous WHMCS ecosystem.

My recommendation: Blesta

Blesta is particularly well suited to an agency managing client hosting because it gives you:

• Separate client accounts — each client can have their own login, invoices, services, and payment method.
• Recurring billing — automatically invoice and collect hosting fees.
• Automatic provisioning/suspension — integrates with cPanel, Plesk, DirectAdmin and other platforms. www.blesta.com
• Client portal + support tickets built in.
• Unlimited clients on its listed licenses, so 25 sites doesn't put you near a pricing ceiling. Current monthly plans start at $17.95/mo. blesta.com
• Multi-company support if you eventually want to operate multiple brands from one installation. www.blesta.com

Blesta vs. WHMCS

WHMCS currently starts at $34.95/mo for up to 250 active clients on its self-hosted plans, while its cloud plans start at $9.99/mo for up to 25 clients. www.whmcs.com

One particularly useful WHMCS feature is usage billing, where you can automatically charge a reseller based on the number of cPanel accounts they create or other tracked metrics. docs.whmcs.com

What I'd actually build

For your situation:

Your agency → reseller hosting account → cPanel/WHM → Blesta → 25 individual client accounts

Each client gets:

1. Their own hosting account
2. Their own Blesta login
3. Their own monthly invoice
4. Automatic credit-card/ACH billing
5. Their own hosting renewal date
6. Ability to open support tickets
7. Ability to upgrade/downgrade their hosting

You can then charge, for example, $25–$50/month per website, while your reseller hosting cost is one underlying infrastructure bill.

Bottom line: I'd choose Blesta for 25 agency-managed sites. I'd choose WHMCS instead if you're planning to turn this into a serious hosting-reseller business with lots of third-party integrations, domains, automation, and potentially hundreds/thousands of customers.

If you tell me whether the 25 clients are WordPress sites and what you currently pay for hosting, I can also recommend the actual reseller hosting provider + server/control-panel setup I'd use.

For 25 client websites, I’d pick WHMCS + cPanel/WHM if your priority is a mature, largely hands-off reseller operation.

My recommendation

Why WHMCS: it can automatically create hosting accounts, handle recurring invoices/payments, upgrades, suspensions, support, and client portals. Its cPanel integration specifically supports shared/reseller hosting and automated provisioning, billing, upgrades, and terminations. docs.whmcs.com

For your situation, I'd structure it like:

Your agency
→ WHMCS
→ cPanel/WHM reseller account
→ Client A's website
→ Client B's website
→ ...
→ Client Y's website

Each client gets their own WHMCS account/service and invoice, while you maintain the underlying reseller infrastructure. You can also charge differently per client—e.g. $30/mo hosting, $50/mo maintenance, $20/mo backups, etc.

But I'd seriously consider Blesta

If you're an agency managing 25 websites rather than a traditional hosting company, Blesta may actually be the better fit.

Blesta supports recurring billing, automatic payments, provisioning, suspension/unsuspension, client portals, support tickets, cPanel/Plesk/DirectAdmin integrations, and multiple companies/brands. www.blesta.com

Its pricing is particularly attractive: Blesta's current plans support unlimited clients, whereas WHMCS uses client-count tiers. blesta.com

What I'd choose for you

If you expect to stay around 25–100 sites:
→ Blesta + cPanel/WHM

If you want to build a serious hosting/reseller business and may have hundreds/thousands of customers:
→ WHMCS + cPanel/WHM

If "separate billing" means each of your 25 clients needs their own invoice/payment portal, both can do this. You don't need 25 separate hosting accounts or 25 billing installations.

One important distinction: reseller hosting provider vs. billing software. WHMCS/Blesta handles your customer billing and automation; cPanel/WHM (or Plesk/DirectAdmin) handles the actual hosting accounts.

If you tell me (1) whether you're currently on cPanel, (2) roughly how much disk/bandwidth the 25 sites use, and (3) whether you want clients to pay you monthly by credit card/ACH, I can recommend the exact reseller hosting + billing stack and estimate your monthly cost.

For 25 client websites, I’d pick WHMCS if your priority is a mature, low-maintenance reseller-hosting operation with each client getting their own billing/account portal.

WHMCS is specifically built around hosting automation: recurring invoices, payment collection, client portals, provisioning, suspension for nonpayment, and integrations with cPanel/Plesk/DirectAdmin. www.whmcs.com

My recommendation

WHMCS's current hosted Starter plan is $9.99/month for up to 25 active clients, while its self-hosted Plus plan starts at $34.95/month for up to 250. www.whmcs.com

Blesta is the alternative I'd seriously consider. Blesta starts at $17.95/month with unlimited clients and has automatic recurring billing, provisioning, suspension/unsuspension, and cPanel/Plesk/DirectAdmin integrations. www.blesta.comwww.blesta.com

One important distinction

If by "separate billing" you mean:

25 websites → 25 separate customers → each gets their own invoice, credit card, renewal, and hosting login

Either WHMCS or Blesta handles this well.

If you mean:

We want to resell hosting to our clients, but keep their hosting completely separated from our agency account

I'd structure it as:

Your agency
→ WHMCS/Blesta
→ reseller hosting account/server
→ Client A → website/account + billing
→ Client B → website/account + billing
→ Client C → website/account + billing
→ etc.

If you're using cPanel/WHM, WHMCS has particularly strong reseller functionality, including tracking the number of cPanel accounts a reseller creates and billing based on those accounts if you want usage-based pricing. docs.whmcs.com

What I'd choose for your 25 sites

WHMCS + cPanel/WHM reseller hosting is my default recommendation.

Use Blesta instead if keeping software costs low and having a simpler, more open/developer-friendly platform matters more than having the biggest hosting ecosystem. Blesta's current pricing is considerably more attractive as you grow beyond 25 clients. www.blesta.comwww.blesta.com

If you tell me whether the 25 clients are all separate companies and whether you're currently on cPanel, Plesk, or WordPress-only hosting, I can recommend the exact hosting provider + WHMCS/Blesta setup + pricing structure I'd use.

For 25 client websites, where each client should have their own account, invoice, payment method, and hosting resources, I’d pick WHMCS + a reseller hosting account.

My recommendation: WHMCS

WHMCS is probably the safest choice if you want this to grow into a proper hosting operation.

It gives you:

• Separate client accounts — each client gets their own login, services, invoices and payment history.
• Automated recurring billing and payment collection.
• Automatic hosting provisioning/suspension when invoices are paid/overdue.
• Integration with cPanel/WHM, Plesk and DirectAdmin.
• Domains, SSL, support tickets and other services can all live in the same client portal.
• It can even track reseller sub-accounts and bill based on usage. docs.whmcs.com
• At your size, the current self-hosted Plus plan supports up to 250 active clients for $34.95/month. www.whmcs.com

The architecture I'd use is:

Your agency
→ WHMCS
→ Reseller hosting account
→ 25 separate cPanel accounts
→ 25 clients with individual billing

That gives you a clean separation: Client A cannot see Client B's hosting or invoices.

One strong alternative: Blesta

Blesta is worth considering if you want something less expensive and more flexible.

Blesta supports client management, automated billing, provisioning, domains and hosting-panel integrations. Its current branded license is $17.95/month with unlimited clients, and it also offers owned licenses. www.blesta.com

I'd choose Blesta over WHMCS if:

• keeping monthly software costs low matters;
• you want an agency/MSP-oriented billing system rather than the most established hosting ecosystem;
• you don't need a huge ecosystem of WHMCS-specific addons.

What I'd actually do for your 25 sites

Important: Don't put all 25 sites into one shared cPanel account. Give every client their own cPanel account so you can suspend, migrate, back up, change limits, and transfer ownership independently.

If by "separate billing" you mean each client should receive their own branded billing portal/invoice, while you pay one wholesale hosting bill, then this setup is exactly what I'd recommend.

If you tell me whether you're currently using cPanel, Plesk, or something else, I can recommend the specific reseller hosting provider + WHMCS/Blesta setup I'd use for 25 sites, including approximate monthly cost.

For 25 client websites with separate client billing, I’d pick WHMCS + a cPanel/WHM reseller account.

My recommendation

1. WHMCS — best overall

• Each client gets their own login, services, invoices, payment history, and support area.
• Automatically creates/suspends hosting accounts based on payment status.
• Handles recurring invoices, Stripe/PayPal, reminders, prorating, taxes, etc. www.whmcs.comwww.whmcs.com
• Integrates tightly with cPanel/WHM and can provision individual accounts automatically. www.whmcs.com
• You can even bill based on the number of cPanel accounts a reseller creates if you eventually resell hosting to your own clients. docs.whmcs.com

At only 25 clients, WHMCS Cloud Starter is currently $9.99/month for up to 25 clients; Growth is $25/month for up to 100. www.whmcs.com

WHMCS

The alternative I'd consider

2. Blesta — best if you want a simpler/leaner system

Blesta does essentially the same core job: client management, recurring billing, payment processing, automated provisioning, suspensions, support tickets, and cPanel/Plesk/DirectAdmin integrations. It also supports multiple companies from one installation with an add-on. www.blesta.com

Blesta

What I'd build for your setup

Your business
     │
     ├── WHMCS
     │     ├── Client A → $X/month
     │     ├── Client B → $X/month
     │     ├── Client C → $X/month
     │     └── ...25 clients
     │

             ├── Website B
             ├── Website C
             └── ...25 websites

Your clients don't need to know or interact with the reseller hosting provider. They pay you; WHMCS handles the billing and the hosting account underneath.

One important distinction: if by "separate billing" you mean each client should receive their own invoice and pay you individually, WHMCS is an excellent fit. If you mean each website needs its own completely isolated hosting account, I'd also make sure the reseller provider gives you individual cPanel accounts rather than putting all 25 sites into one account.

For your size, I'd choose WHMCS Cloud + a reputable cPanel reseller host unless you specifically want maximum control/self-hosting. If you tell me your monthly hosting budget and whether you need email hosting, WordPress, or just website hosting, I can narrow it down to the best 2–3 reseller providers for your 25 sites.
