ChatGPT answers, unedited

For a nonprofit selling PDFs, workbooks, and training materials, I’d focus on solutions that keep recurring costs and transaction fees low while making digital delivery easy.

My shortlist

1. Easy Digital Downloads — my first choice for your use case

easydigitaldownloads.com is specifically designed around digital products. It supports PDFs and other downloadable products, with unlimited products and no listing fees. Easy Digital Downloads

The important advantage is that you're not paying for a bunch of physical-commerce functionality you don't need. The core WordPress plugin is free, while some advanced functionality requires paid extensions. Its current paid plans start at $99.50/year during the listed promotion, but you don't necessarily need a paid plan to get started. Easy Digital Downloads

It also supports pay-what-you-want/custom pricing, which could be particularly useful for a nonprofit. Easy Digital Downloads

I'd choose EDD if: your catalog is mostly PDFs, ebooks, training downloads, recordings, templates, or other digital resources.

2. WooCommerce — best if you already use WordPress

woocommerce.com is free and open source, with no platform revenue share. You pay your hosting and payment processor rather than a WooCommerce subscription. WooCommerce WooCommerce

It handles downloadable products natively, including download links, expiration settings, and protected download delivery. WooCommerce WooCommerce

I'd lean toward WooCommerce if you also expect to sell things like printed books, merchandise, event registrations, memberships, or physical training materials later.

3. Payhip — easiest low-tech option

If nobody on your team wants to maintain WordPress, I'd look at Payhip. You trade some control for simplicity: the storefront, checkout, and digital delivery are handled for you.

That's potentially worth it for a small nonprofit where staff time is more expensive than software.

What I'd actually do

If you already have a WordPress website:

WordPress + Easy Digital Downloads + Stripe/PayPal

Keep the initial setup extremely lean:

• Free WordPress theme
• Free EDD core
• Stripe and/or PayPal
• PDFs hosted through the ecommerce system
• Automatic purchase/download emails
• Coupons for partner organizations
• Free PDFs as email-list lead magnets
• Pay-what-you-want pricing for selected resources

If you don't have WordPress and want something that a nontechnical staff member can operate, I'd choose a hosted service instead of building an open-source stack.

One particularly useful nonprofit feature to consider is "pay what you can" pricing. EDD supports custom prices with optional minimums, so you could have, for example, $10 suggested / $0 minimum for community-access materials while charging a normal price for professional training. Easy Digital Downloads

If you tell me roughly (1) how many PDFs you sell, (2) your monthly sales volume, (3) whether you already have WordPress, and (4) whether you need memberships/courses, I can lay out the cheapest practical setup and estimated annual cost for your nonprofit.

It also supports pay-what-you-want/custom pricing, which could be particularly useful for a nonprofit. Easy Digital Downloads

I'd choose EDD if: your catalog is mostly PDFs, ebooks, training downloads, recordings, templates, or other digital resources.

2. WooCommerce — best if you already use WordPress

One particularly useful nonprofit feature to consider is "pay what you can" pricing. EDD supports custom prices with optional minimums, so you could have, for example, $10 suggested / $0 minimum for community-access materials while charging a normal price for professional training.

For a nonprofit selling mostly PDFs/training materials, I’d shortlist:

• WooCommerce — best if you already use WordPress. Free/open-source; digital downloads work well, and you mainly pay hosting + payment processing. WooCommerce CartMango
• Easy Digital Downloads — purpose-built for digital products and simpler than WooCommerce for downloads. Free core, with paid extensions starting around $99.50/year. Capterra Plugin Scout
• Gumroad — easiest/no-maintenance option. No monthly fee, but direct sales cost 10% + $0.50, so it becomes expensive as sales grow. Gumroad Gumroad

My pick: If you already have WordPress, start with WooCommerce. If you want the simplest possible setup and expect modest sales, Gumroad may be worth the transaction fees.

For a nonprofit selling PDFs, downloadable guides, and training materials, I’d narrow it to three practical options:

My practical recommendation: Payhip

For a very tight budget, I would start with payhip.com.

Its free plan is $0/month + 5% per transaction, with unlimited products and revenue, and it includes the core features rather than putting them behind different tiers. Payment processing fees from Stripe/PayPal are additional. Payhip Payhip

That's particularly attractive for a nonprofit because you don't have to pay for hosting, security updates, ecommerce plugins, or a developer just to get started.

It also supports pay-what-you-want pricing, which could be useful for nonprofit materials—for example, setting a $10 minimum while allowing supporters to contribute more. Payhip Help Center

Payhip also says it can automatically handle EU VAT and UK VAT, which removes another administrative burden if you sell internationally. Payhip

If you want true open source: Easy Digital Downloads

If you already have a WordPress website and are comfortable maintaining it, I'd look at easydigitaldownloads.com.

It's specifically designed around digital products, rather than adapting a physical-product store to PDFs. Its free core is available through WordPress, while more advanced capabilities can require paid extensions. PluginScout Software Advice

This makes more sense if you want:

• Full ownership of your store and customer experience
• Your ecommerce system integrated tightly into your existing nonprofit website
• More control over memberships, recurring payments, licensing, etc.
• The ability to customize things yourself

The downside is that "free/open source" doesn't mean zero cost: you'll still have hosting, payment-processing costs, backups, maintenance, and potentially paid extensions.

What about WooCommerce?

woocommerce.com is also open source and its core platform is free, with no revenue share. WooCommerce

I'd choose it if you expect to sell both digital and physical products, or eventually need a fairly sophisticated ecommerce operation. For a nonprofit whose primary products are PDFs and training downloads, though, it can be more machinery than necessary.

One option I'd put behind Payhip

gumroad.com is extremely easy to use and has no monthly fee, but its current direct-sale fee is 10% + $0.50 per transaction, substantially higher than Payhip's free-plan platform fee. Gumroad also charges 30% for sales originating through its Discover marketplace. Gumroad Gumroad

For a nonprofit operating on thin margins, that difference can become significant.

So my short version: start with Payhip if you want to launch cheaply with almost no technical work; choose Easy Digital Downloads if you already run WordPress and want long-term ownership/control.

If you tell me roughly how many PDFs you sell, your average price, monthly sales, whether you already have WordPress, and whether you need memberships/courses, I can calculate the approximate annual cost of each and show you which setup has the lowest total cost.

For a nonprofit selling PDFs, guides, curricula, and training materials on a tight budget, I’d usually avoid expensive all-in-one platforms and choose something that gives you ownership of your content and low ongoing costs.

My top recommendations:

1. Best overall: WordPress + Easy Digital Downloads (EDD)

WordPress + Easy Digital Downloads is probably the best fit for your use case.

Why it fits nonprofits selling digital materials:

• Built specifically for digital products (PDFs, ebooks, training files, downloads)
• No marketplace listing fees
• You control your website and customer data
• Works with common payment processors like Stripe and PayPal
• Can add donations, memberships, discount codes, and email marketing later

Easy Digital Downloads has a free core plugin and is designed around selling downloadable products. WordPress.org It is also specifically marketed for nonprofit digital fundraising and educational resources. Easy Digital Downloads

Typical cost:

• WordPress software: free
• EDD: free to start
• Hosting: roughly $5–15/month
• Payment processing: usually ~2.9% + small transaction fee (varies by processor)

Good setup:

• WordPress site
• Easy Digital Downloads
• Stripe
• MailerLite or Brevo for email
• Cloud storage/CDN if PDFs become large

2. Best if you already have WordPress: WooCommerce

WooCommerce is more general-purpose but very flexible.

Choose this if you might later sell:

• printed manuals
• event tickets
• merchandise
• memberships
• bundled courses

WooCommerce supports downloadable products with purchase-based file access and download management. WooCommerce

Pros

• Huge ecosystem
• Lots of nonprofit integrations
• Can combine sales and donations

Cons

• More complicated than EDD
• More plugins may be needed

3. Lowest maintenance: Gumroad or Payhip-style hosted platforms

If you have very little technical capacity, a hosted digital-download service can be easier.

Pros

• No website maintenance
• Upload PDF → create product → sell
• Handles checkout and delivery

Cons

• Less control
• Fees can become significant as sales grow
• Less integrated with your nonprofit website

4. If donations are a major part of the model: WordPress + EDD + donation plugin

If you sell materials but also rely on contributions, consider adding a donation system such as GiveWP. It provides donation forms and fundraising tools for WordPress sites. WordPress.org

A common nonprofit setup:

• Free resources → email signup
• Paid training bundles → EDD/WooCommerce
• Donations → GiveWP
• Newsletter → MailerLite/Brevo

My recommendation by situation

For a small nonprofit, I’d start with WordPress + Easy Digital Downloads, keep the setup simple, and only add paid extensions when revenue justifies them. It gives you the lowest long-term cost without locking your organization into a vendor. WordPress.org WooCommerce

If you tell me roughly how many PDFs you sell per month, whether you already have a website, and whether buyers are individuals or organizations (schools/governments/NGOs), I can narrow this down further.

For a nonprofit selling PDFs, guides, recordings, and training materials, I’d strongly favor a WordPress-based solution over Shopify or a custom platform.

My top recommendation: WordPress + WooCommerce

woocommerce.com is free and open source, and its core platform has no monthly subscription and no revenue share. You pay for hosting and payment processing, plus any optional extensions you choose. It supports downloadable/digital products natively. WooCommerce WooCommerce

A very lean setup could be:

• WordPress — your website/content
• WooCommerce — storefront and checkout
• Stripe or PayPal — payments
• A low-cost WordPress host
• A free/lightweight WordPress theme
• Your PDFs uploaded as downloadable products
• Email marketing through whatever service you're already using

That gives you a surprisingly capable store without committing to a $30–$100+/month ecommerce platform.

Why I like it for a nonprofit

WooCommerce gives you control over your data and doesn't charge an additional percentage simply because you're using a third-party payment processor. WooCommerce

You can also do things that are particularly useful for nonprofits, such as:

• Sell a PDF for $10
• Give certain PDFs away for free
• Create discount codes for students, members, or partner organizations
• Bundle several training materials
• Eventually add memberships or subscriptions
• Potentially implement "pay what you can" pricing if that's part of your fundraising model

The last one can be done with extensions; WooCommerce even has an extension specifically designed for customer-entered pricing. WooCommerce

A very good alternative: Easy Digital Downloads

If you're 100% digital and don't expect to sell physical products, I'd also look seriously at easydigitaldownloads.com.

It's specifically designed around selling digital files rather than physical merchandise. The free version is available, while paid plans add things such as subscriptions, advanced marketing, reporting, and additional payment functionality. Easy Digital Downloads

I'd choose EDD over WooCommerce if your store is basically:

PDFs + ebooks + video/audio downloads + online training + digital memberships

It's a cleaner conceptual fit.

What I would not do on a tight budget

I wouldn't start with Shopify unless you particularly value having someone else manage the technical infrastructure. It's convenient, but you're paying for that convenience.

I also wouldn't build a custom ecommerce system. For a small nonprofit, your scarce resource is probably staff time, not software licenses.

My budget ranking

WooCommerce's own current pricing information puts typical hosting at roughly $25–$350/month, although a very small nonprofit store can often operate below that range with inexpensive shared/managed WordPress hosting. WooCommerce

What I'd build in your situation

I'd aim for a $10–30/month-ish infrastructure budget initially, excluding payment processing:

WordPress → WooCommerce → Stripe → PDF downloads

Then spend money only when you have a demonstrated need—for example, memberships, recurring subscriptions, sophisticated email marketing, or protected training content.

If you tell me roughly how many PDFs/products you have, your expected monthly sales, whether you already have a WordPress website, and whether you need subscriptions/memberships, I can lay out a specific $0 / $25 / $50-per-month nonprofit stack and tell you exactly which plugins I'd use.

For a nonprofit selling PDFs, guides, and training materials, I’d prioritize low fixed costs, simple digital delivery, and minimal maintenance.

My shortlist

🥇 I'd start with Payhip

For a cash-strapped nonprofit, Payhip is probably the sweet spot. Its free plan is $0/month with a 5% transaction fee, includes unlimited products and revenue, and supports digital downloads. Customers can receive their files immediately after purchase. payhip.com

It also supports pay-what-you-want pricing, which could be particularly useful for a nonprofit—for example, a training PDF could be "$10 minimum, pay more if you can." help.payhip.com

There's another nice nonprofit-specific point: Payhip says it offers charity discounts, so I'd contact them before committing. payhip.com

You could essentially have:

Your existing website → "Training & Resources" → Payhip checkout → automatic PDF delivery

No server administration, ecommerce plugin maintenance, or complicated setup.

🛠️ If "open source" is a priority: WooCommerce

If you already have a WordPress website and want to own/control the entire store, I'd choose WooCommerce.

WooCommerce itself is free and open source, with no platform revenue share. You pay for hosting and any extensions you choose. woocommerce.com

The downside is that you're taking on more responsibility: WordPress updates, backups, security, payment configuration, and troubleshooting.

For a nonprofit with someone technically comfortable maintaining WordPress, though, it can be an excellent long-term solution.

Why I wouldn't choose Gumroad first

Gumroad is wonderfully simple, but its current direct-sale fee is 10% + $0.50 per transaction, and marketplace-discovery sales are 30%. gumroad.com

For inexpensive nonprofit PDFs, that can eat a surprisingly large percentage of your revenue.

For example, on a $10 PDF, the $0.50 fixed fee alone is 5%, before the 10% platform fee and other applicable processing/tax costs.

What I'd actually do

If your budget is extremely tight:

Payhip Free + your existing website + Stripe/PayPal

Then upgrade only when the transaction fees become more expensive than the monthly plan. Payhip's Plus plan is currently $29/month + 2%, while Pro is $99/month with no transaction fee. payhip.com

If you already run WordPress and have technical help:

WordPress + WooCommerce + inexpensive hosting

That gives you the greatest control and avoids platform revenue sharing, but costs more in time and maintenance. woocommerce.com

One other consideration: if your "training materials" include video courses, memberships, certificates, quizzes, or recurring access, I'd evaluate the architecture differently than if they're primarily PDFs. Payhip can handle courses and memberships too, but a dedicated learning-management setup may make more sense as you grow. payhip.com

If you tell me (1) whether you already have a WordPress/other website, (2) roughly how many PDFs/products you have, and (3) your expected monthly sales, I can recommend the cheapest setup and estimate your annual cost for 3–4 options.

For a nonprofit selling PDFs, guides, curricula, and training materials on a tight budget, I would avoid heavyweight ecommerce platforms and focus on digital-download-first tools. Your biggest needs are likely:

• Low/no monthly fees
• Secure PDF delivery after payment
• Discount codes (for partners, donors, students)
• Tax/VAT handling if needed
• Donation + product sales integration
• Easy maintenance by nontechnical staff

My top recommendations:

1. Best overall: WordPress + Easy Digital Downloads (EDD)

easydigitaldownloads.com

Best fit: A nonprofit that already has (or can create) a WordPress website.

Why I’d pick it:

• Built specifically for selling digital products like PDFs, ebooks, templates, and training resources. WordPress.org
• Free core plugin; you mainly pay for hosting and optional add-ons.
• Handles download links, customer accounts, purchase history, and digital delivery. WordPress.org
• Easier than configuring a full ecommerce store.

Typical budget:

• WordPress hosting: ~$5–15/month
• Domain: ~$10–20/year
• EDD core: free
• Payment processing: usually Stripe/PayPal transaction fees only

Good nonprofit setup:

• WordPress + EDD
• Stripe nonprofit account (if eligible)
• Mailchimp/Brevo free tier for email follow-up
• Optional membership plugin if you later add paid training access

2. Cheapest DIY option: WordPress + WooCommerce

woocommerce.com

Best fit: You may eventually sell physical books, event tickets, memberships, or donations alongside PDFs.

Pros:

• Free open-source core
• Huge ecosystem
• More flexible than most alternatives

Cons:

• More setup complexity
• Easy to accidentally add lots of paid extensions
• More maintenance

WooCommerce can sell digital products, but it is a broader ecommerce system rather than a digital-download specialist. Kinsta®

3. Lowest maintenance (not open source): Payhip

payhip.com

Best fit: A very small nonprofit that does not want to maintain a website store.

Pros:

• Fast setup
• Handles file delivery
• No hosting headaches

Cons:

• Less control over customer data and branding
• Platform dependency
• Transaction fees on lower tiers

4. If you already use Drupal: Drupal Commerce

drupalcommerce.org

Best fit: Larger nonprofits already running Drupal.

Drupal Commerce can be extended for paid file downloads and training access, including download licensing controls. Drupal.org

It is powerful, but I would not choose it for a small nonprofit starting from scratch unless you already have Drupal expertise.

What I would avoid for your situation

• Magento/Open Source enterprise platforms — too much hosting and technical overhead.
• Shopify — excellent product, but monthly fees and app costs add up for a nonprofit selling mostly PDFs.
• Building a custom store — rarely worth the maintenance burden.

My suggested nonprofit stack

For most small organizations:

Website: WordPress
Store: Easy Digital Downloads
Payments: Stripe + PayPal
Files: Store PDFs through EDD or private cloud storage
Email: Brevo or Mailchimp
Accounting: Export monthly sales reports

You could realistically launch this for under $200/year if you already have a website and do the setup yourself.

A couple of questions would help narrow this down:

1. Do you already have a website (WordPress, Wix, Squarespace, Drupal, etc.)?
2. Are these PDFs mostly one-time purchases, or are you selling ongoing training/memberships/courses?
3. Roughly how many products do you expect (10 PDFs vs. hundreds of resources)?

For a nonprofit selling PDFs, guides, and training materials on a tight budget, I would usually avoid a full SaaS ecommerce platform (Shopify, etc.) and choose a solution where you own your website, customer list, and files.

My top recommendations:

1. Best overall: WordPress + Easy Digital Downloads (EDD)

Best fit if you mainly sell digital resources. Easy Digital Downloads WordPress.org

Why I’d pick it for your nonprofit:

• Built specifically for digital products (PDFs, ebooks, courses, downloads)
• No marketplace commission
• Automatic delivery of files after payment
• Discount codes, customer accounts, reporting
• Works well alongside donation tools and nonprofit websites Easy Digital Downloads

Typical budget:

• WordPress software: free
• Hosting: ~$5–15/month
• Payment processing: usually just Stripe/PayPal transaction fees
• EDD free version can get you started; paid add-ons are optional as you grow WordPress.org

Good stack:

• WordPress
• Easy Digital Downloads
• Stripe
• A nonprofit donation plugin (if you also accept donations)
• Mailchimp/Brevo/another email tool for supporter follow-up

This would be my first choice for a small nonprofit.

2. Best if you already have WordPress: WooCommerce

WooCommerceWooCommerce is more general-purpose but very capable.

Choose it if:

• You may sell physical items later (books, merchandise, event tickets)
• You need a larger ecosystem of plugins
• You already have a WordPress site with WooCommerce experience

Downside: it is heavier than you need for a PDF-only store. Digital downloads work well, but you may spend more time configuring features that EDD handles more naturally. Kinsta®

3. Lowest-maintenance option: Gumroad or similar hosted platforms

Good if you want to avoid managing a website.

Pros:

• Very easy setup
• Handles checkout and file delivery
• No server maintenance

Cons:

• Less control over branding
• Platform fees can become significant
• Customer ownership/marketing flexibility may be more limited

4. If training is your main product: Moodle + ecommerce

If your “training materials” are becoming actual courses (lessons, quizzes, certificates, student tracking), consider an open-source learning platform such as Moodle with ecommerce capabilities. ModernCommerce

My recommended nonprofit setup

For a small organization, I’d build:

1. Website: WordPress
2. Store: Easy Digital Downloads
3. Payments: Stripe + PayPal
4. Files: Store downloads securely (not just public PDF links)
5. Email: collect purchaser/supporter emails for future campaigns
6. Donations: add a donation tool alongside sales

A realistic starting cost can be around $100–200/year if you handle setup yourselves (mostly hosting/domain), plus payment fees.

A few questions would change the recommendation:

• Do you already have a website (WordPress, Wix, Squarespace, etc.)?
• About how many PDFs/products do you sell (5, 50, 500+)?
• Do you need memberships or course access, or just one-time PDF purchases?
• Are buyers mostly individuals, or organizations buying training licenses?

For a nonprofit selling PDFs, guides, workbooks, and training materials, I’d prioritize low fixed costs, easy digital delivery, and the ability to offer discounts/free materials or pay-what-you-want pricing.

My recommendation: Payhip

Payhip is probably the best starting point for your situation.

• $0/month on its Free Forever plan, with a 5% transaction fee. Payment processor fees are additional. Payhip
• Handles PDFs and other digital files, with files up to 5 GB each. Payhip Help Center
• Supports pay-what-you-want, including minimum prices such as $5+—particularly useful for nonprofit fundraising. Payhip Help Center
• You can make materials completely free, which is useful for outreach/education. Payhip Help Center
• It can embed checkout into an existing website, so you don't necessarily need to rebuild your nonprofit's site. Payhip
• Payhip says it offers charity discounts, so I'd contact them and ask specifically what they can offer a registered nonprofit. Payhip

payhip.com

If you want truly open source: WooCommerce

WooCommerce is my choice if you already have WordPress and/or have someone comfortable maintaining a website.

The core WooCommerce software is free and open source, with no platform revenue share. You pay for hosting, payment processing, and any extensions you choose. WooCommerce

The downside is complexity. For a small nonprofit selling only digital materials, maintaining WordPress, plugins, security, backups, payment integrations, etc. can become a bigger burden than the software cost itself.

woocommerce.com

Another easy option: Gumroad

Gumroad is extremely easy to set up and handles digital delivery and tax administration. But its standard direct-sale fee is 10% + $0.50 per transaction, so I'd generally choose Payhip for a budget-conscious nonprofit. Gumroad Gumroad

Gumroad does have a nice pay-what-you-want feature, including free products. Gumroad

gumroad.com

What I'd choose

One important distinction: "open source" isn't necessarily "cheapest." For a nonprofit with limited staff time, a hosted service like Payhip can be considerably cheaper in practice because you're not spending volunteer/staff hours maintaining the store.

If you tell me roughly how much you expect to sell per month (e.g. $500, $2,000, $10,000) and whether you already have a WordPress website, I can calculate the actual annual cost of Payhip vs. WooCommerce and recommend the cheapest setup.

If you're a small nonprofit selling mostly PDFs, workbooks, and training materials, I’d avoid an expensive all-in-one ecommerce platform. You can keep this very lean.

My top picks

1. Payhip — probably what I'd choose

payhip.com is particularly well suited to a small nonprofit.

Its free plan is $0/month + 5% per transaction, with unlimited products and revenue. You still pay the normal Stripe/PayPal processing fees. It supports PDFs and other downloadable files, and you can offer pay-what-you-want pricing—which is particularly useful for nonprofit educational materials. Payhip Payhip Help Center

For example, you could have:

• “Community Health Training Manual — $15”
• “Volunteer Handbook — $10”
• “Free Training Guide — $0+”
• “Complete Training Bundle — $35”

The 0+ / 10+ model lets people contribute more if they want. Payhip Help Center

Big advantage: almost no technical maintenance. You upload the PDF, set the price, and Payhip handles checkout and delivery.

2. WooCommerce — best if you want to own the whole system

woocommerce.com is free and open source, with no platform revenue share. You pay for WordPress hosting and whatever extensions you actually need. WooCommerce

I'd choose this if you already have a WordPress nonprofit website and want the store integrated into it.

A basic setup could be:

WordPress + WooCommerce + Stripe/PayPal + downloadable PDFs

That can be extremely inexpensive, and you retain much more control over your website, customer data, branding, and checkout.

The downside is that you become responsible for updates, backups, security, hosting, and troubleshooting. For a volunteer-run nonprofit, that maintenance burden can matter more than the software price.

3. Easy Digital Downloads

easydigitaldownloads.com is another WordPress option, and it's specifically designed around digital products rather than physical merchandise. That's a nice fit for PDFs and training materials.

I'd consider it if your catalog is going to become substantial—lots of downloadable resources, bundles, memberships, recurring access, licensing, etc.

For a very small organization, though, WooCommerce or Payhip is likely simpler/cheaper overall.

4. Gumroad

gumroad.com is incredibly easy, but I'd put it below Payhip for a nonprofit because of the transaction fees.

Gumroad currently charges 10% + $0.50 on direct/profile sales, with a 30% fee for sales originating through its Discover marketplace. Gumroad Gumroad

For a $10 PDF, that $1.50 platform fee is significant when you're trying to maximize funds going to your mission.

What I'd actually build

If your requirements are simply:

“We have a nonprofit website and want to sell PDFs/training materials without spending much money.”

I'd start with:

Your existing website → Payhip → Stripe/PayPal → automatic PDF delivery

You could get the whole thing running without paying a monthly ecommerce subscription.

If you already have WordPress and someone on your team is comfortable maintaining it, I'd instead do:

WordPress → WooCommerce → Stripe → downloadable products

That gives you the lowest long-term platform costs and the most ownership.

One other option worth looking at is zeffy.com if your nonprofit's sales are closely tied to donations/fundraising. Its model is specifically aimed at nonprofits and advertises $0 platform and payment-processing fees, although I'd verify that its digital-product workflow fits your particular PDF/training use case before committing. Zeffy

My ranking for you: Payhip → WooCommerce → Easy Digital Downloads → Zeffy → Gumroad.

If you tell me (1) whether you already have a WordPress website, (2) roughly how many PDFs you sell, and (3) your approximate monthly sales, I can recommend the cheapest setup and estimate your actual annual cost.

For a nonprofit selling PDFs, workbooks, training materials, and other digital downloads on a tight budget, I’d narrow it to two choices:

My recommendation

1. Payhip — best if you want the simplest/cheapest launch

payhip.com is probably where I’d start if you don’t already have a WordPress site.

• $0/month on the Free Forever plan.
• 5% Payhip transaction fee, plus normal Stripe/PayPal processing fees.
• Unlimited products and revenue even on the free plan.
• Handles digital downloads, including PDFs.
• Supports coupons, bundles, pay-what-you-want pricing, and embedded checkout.
• Payhip specifically says it offers charity discounts, so I'd ask them about a nonprofit rate. Payhip Payhip

The big advantage is that you don't have to become your own IT department. You can get a storefront running quickly and put your money toward your nonprofit's mission rather than hosting and maintaining ecommerce software.

I'd choose Payhip if: you're selling perhaps 10–100 digital products and want something that just works.

2. WooCommerce — best if you already use WordPress and want ownership

woocommerce.com is my choice if you already have a WordPress website and are comfortable maintaining it.

WooCommerce itself is free and open source, with no platform revenue share. You pay for hosting and whatever extensions you choose, while payment processors charge their normal fees. WooCommerce WooCommerce

For a nonprofit, this gives you considerably more control:

• Sell PDFs and other downloads.
• Keep your customer/order data under your control.
• Create member-only or donor-only resources.
• Add subscriptions or memberships later.
• Integrate with your existing WordPress site.
• Add nonprofit-specific functionality as needed.
• Avoid being locked into one ecommerce vendor.

The downside is that your real cost isn't $0. You'll need WordPress hosting, backups, security, and potentially paid extensions. WooCommerce estimates hosting for typical stores at roughly $25–$350/month, although a small nonprofit site can potentially run considerably below that with inexpensive hosting. WooCommerce

What I'd do in your situation

One important nonprofit feature

I'd seriously consider pay-what-you-can pricing rather than simply putting everything at a fixed price. That's particularly appropriate for training materials where some users may be individuals with limited resources while organizations can afford to contribute more.

Payhip supports pay-what-you-want pricing directly. Payhip

My bottom line: If you're starting from scratch, start with Payhip's free plan. If you already have a WordPress site and expect the store to become an important part of the nonprofit, WooCommerce is the better long-term foundation.

If you tell me roughly how many PDFs you sell, your monthly sales volume, whether you already have WordPress, and whether you need memberships/courses, I can recommend a specific $0–$25/month setup and estimate your transaction costs.

For a nonprofit selling PDFs, workbooks, guides, and training materials, I’d keep the stack very simple. My top two choices are Payhip if you want minimal technical work, or WordPress + WooCommerce if you want maximum control.

My recommendation

1. Best for a tiny budget + minimal hassle: Payhip

payhip.com is probably the easiest place to start.

• $0/month on its Free Forever plan, with a 5% transaction fee. Payhip Payhip
• Supports PDFs and other digital downloads, with files up to 5 GB each. Payhip Help Center
• Handles delivery after purchase, so you don't have to build your own download system.
• Supports pay-what-you-want pricing, which is particularly useful for a nonprofit. Payhip Help Center
• Also supports courses and memberships if your "training materials" eventually become a more structured program. Payhip
• Payhip says it offers charity discounts, so I'd contact them before paying for an upgraded plan. Payhip

I'd choose this if: you're spending more time producing educational material than managing websites and servers.

2. Best open-source option: WordPress + WooCommerce

woocommerce.com is free and open source, with no platform revenue share. You pay for hosting and payment processing instead. WooCommerce WooCommerce

This is attractive if you already have a WordPress nonprofit website:

WordPress → WooCommerce → Stripe/PayPal → digital PDF delivery

Advantages:

• You own the store and its data.
• No monthly ecommerce platform fee.
• Excellent for combining articles + resources + donations + products on one site.
• Can sell both digital and physical products later.
• Huge ecosystem of inexpensive/free plugins.
• You can add pay-what-you-want functionality if needed.

The downside is that you become responsible for hosting, updates, backups, security, and plugins. WooCommerce estimates typical hosting at roughly $25–$350/month, although a small nonprofit site can potentially run substantially below that with an inexpensive host. WooCommerce

3. If you're already on WordPress: Easy Digital Downloads

I'd also look seriously at easydigitaldownloads.com.

It's specifically designed for digital products rather than physical merchandise, including PDF documents, and allows unlimited products without listing fees. Easy Digital Downloads

For a store that's 100% PDFs/training downloads, I actually prefer its conceptual fit over WooCommerce.

What I'd pick for your situation

One important nonprofit consideration: don't automatically assume "open source" is cheaper. With a small catalog and low sales volume, Payhip's 5% fee may cost less than your time maintaining WordPress, plugins, hosting, backups, and security. Once sales become substantial, however, the economics can flip in favor of self-hosting.

If you tell me roughly how many PDFs you sell, your monthly sales ($), whether you already have a WordPress website, and whether you need donations/memberships/courses, I can recommend a specific $0–$30/month stack and estimate your annual cost.

For a nonprofit selling PDFs, guides, toolkits, and training materials, I would avoid a full enterprise ecommerce system. Your biggest needs are likely:

• low monthly cost
• automatic delivery of files after payment
• donation capability
• simple administration for staff/volunteers
• ownership of your customer list
• minimal technical maintenance

My top recommendations:

1. Easy Digital Downloads + WordPress — best overall fit

Best if you already have (or can build) a WordPress site.

Why I’d pick it:

• Designed specifically for digital products (PDFs, ebooks, courses, downloads). WordPress.org
• Free core plugin available.
• Handles checkout, payment integration, download links, customer records, and discount codes. WordPress.org
• Works well alongside nonprofit donation tools. Easy Digital Downloads
• You own your website and customer data.

Typical budget:

• WordPress hosting: ~$5–15/month (depending on provider)
• Domain: ~$10–20/year
• Payment processing: usually only credit card processor fees
• Optional paid plugins later as you grow

Good setup:

• WordPress
• Easy Digital Downloads
• Stripe or PayPal
• A donation plugin
• Email newsletter tool (for supporter follow-up)

This is the option I’d recommend for most small nonprofits.

2. WooCommerce — best if you may sell physical items later

Choose this if you might eventually sell:

• printed manuals
• books
• merchandise
• event tickets
• memberships

Pros:

• Huge ecosystem
• Free core software
• Works with digital downloads
• Lots of nonprofit-friendly integrations

Cons:

• More configuration than you need for PDFs alone
• Extensions can add cost and complexity

WooCommerce is more of a general store builder, while Easy Digital Downloads is more focused on digital goods. Kinsta®

3. Gumroad or similar hosted platforms — easiest, but less ownership

Good if you want something running quickly without maintaining a website.

Pros:

• No server maintenance
• Upload PDF → create product → sell
• Simple checkout

Cons:

• Less control over branding
• Platform fees can matter when revenue grows
• Customer relationship tools are more limited

I’d use this for a pilot project, not necessarily as your long-term nonprofit store.

4. Drupal Commerce — only if you already use Drupal

Drupal Commerce can handle digital files and access control, but it is usually more technical to maintain. Drupal.org

I would not choose it for a small nonprofit starting from scratch unless you already have Drupal expertise.

My suggested low-cost nonprofit stack

For a small organization, I’d build:

• Website: WordPress
• Store: Easy Digital Downloads
• Payments: Stripe + PayPal
• Files: protected download delivery (not public Dropbox links)
• Donations: nonprofit donation plugin
• Email: free/low-cost newsletter platform
• Analytics: privacy-friendly analytics if desired

A practical launch budget can be under $200/year if you do the setup yourselves and keep plugins minimal.

One question would change my recommendation: Do you already have a website (WordPress, Wix, Squarespace, Drupal, etc.), or are you starting from scratch?

My suggested low-cost nonprofit stack

For a small organization, I’d build:

For a nonprofit selling PDFs, ebooks, workbooks, and training materials, I’d prioritize low fixed costs, easy digital delivery, and minimal technical maintenance.

My top picks

1. Payhip — best overall for a tight budget

payhip.com

This would be my first choice if you don't want to manage software yourself.

• $0/month on the Free Forever plan
• 5% Payhip transaction fee, plus normal Stripe/PayPal processing
• Unlimited products and revenue on the free plan
• Automatic delivery of PDFs after purchase
• Pay-what-you-want pricing
• Coupons, affiliates, and other marketing features
• Can operate as your storefront or embed into an existing nonprofit website
• Payhip specifically supports selling PDFs and documents. Payhip Payhip Payhip
• They explicitly say they offer charity discounts, so I'd contact them about your nonprofit status. Payhip

Why I like it for you: You can start for essentially $0 upfront and don't need to hire someone to maintain WordPress/plugins/server software.

2. WooCommerce + WordPress — best open-source option

woocommerce.com

If open source and ownership/control are your priorities, I'd choose WooCommerce.

WooCommerce itself is free and open source, with no platform revenue share or monthly subscription. You pay separately for hosting, payment processing, and any extensions you choose. WooCommerce

A typical setup would be:

WordPress → WooCommerce → digital-download products → Stripe/PayPal

Advantages

• Full control of your store and customer experience
• Excellent if you already have a WordPress nonprofit website
• Huge ecosystem
• Can sell PDFs, courses, physical products, memberships, donations, etc.
• Much easier to customize as your organization grows

Downside: The software is free, but hosting and maintenance aren't. You'll also need to be comfortable with WordPress updates, backups, security, and occasionally dealing with plugins.

My advice: If you're already running WordPress, this becomes a much more compelling option.

3. Gumroad — easiest, but relatively expensive per sale

gumroad.com

Gumroad is extremely easy for digital products and has no monthly fee. But its current direct-sale fee is 10% + $0.50 per transaction, before applicable payment-processing considerations; marketplace/discovery sales can be 30%. Gumroad Gumroad

It does have useful nonprofit-friendly-ish functionality such as pay-what-you-want pricing, including free products. Gumroad

I'd choose Gumroad primarily if simplicity matters more than minimizing transaction costs.

What I'd choose

One important consideration for a nonprofit

I'd avoid building your own payment/download system just to save a few dollars. Secure payment processing, download protection, receipts, refunds, tax handling, and customer accounts quickly become a maintenance burden.

For your situation, I'd start with Payhip Free, ask them about their nonprofit/charity discount, and only move to WooCommerce if you eventually need substantially more control.

If you tell me roughly how many PDFs you sell, average price, monthly sales/revenue, and whether you already have a WordPress website, I can calculate the actual annual cost of Payhip vs. WooCommerce vs. Gumroad for your nonprofit.

For a nonprofit selling mostly PDFs, ebooks, workbooks, and training materials, I’d keep this much simpler than a traditional online store.

My recommendation

🥇 Best overall for a tight budget: Payhip

payhip.com is probably the best fit if you want low upfront cost + minimal technical work.

• $0/month on its Free Forever plan.
• 5% transaction fee on sales, plus Stripe/PayPal processing.
• Unlimited products and revenue even on the free plan.
• Customers automatically receive download links after purchase.
• Supports PDFs and other digital files, including multiple files per product.
• Has pay-what-you-want pricing, which is particularly useful for a nonprofit.
• Can embed checkout into an existing website. Payhip Payhip Payhip Help Center

For example, you could have:

Free Community Training Guide — $0+
Volunteer Handbook — $10+
Complete Training Bundle — $35
Organization License — $100

That lets people who can't afford the materials access them while giving supporters an easy way to contribute more.

🥈 Best if you already run WordPress: WooCommerce

woocommerce.com is open source and free, with no platform revenue share. You pay for hosting, payment processing, and any extensions you choose. WooCommerce currently estimates typical hosting at roughly $25–$350/month depending on the store, although a very small nonprofit can potentially run considerably cheaper with appropriate hosting. WooCommerce

I'd choose this if:

• You already have a WordPress website.
• You want complete ownership/control.
• You expect the store to become more sophisticated.
• You want to integrate donations, memberships, events, newsletters, etc.
• Someone on your team is comfortable maintaining WordPress.

The downside is that you become responsible for updates, security, backups, hosting and troubleshooting.

🥉 Easiest alternative: Gumroad

gumroad.com is extremely easy to launch and has no monthly fee. Its current direct-sale fee is 10% + $0.50 per transaction, before payment-processing costs; marketplace/discovery sales are 30%. It also handles sales-tax obligations as merchant of record. Gumroad Gumroad

It's attractive if your priority is:

"I want to upload my PDFs today and not think about ecommerce infrastructure."

But for a nonprofit, I'd generally prefer Payhip because the ongoing transaction fee is lower.

What I'd pick for your situation

My choice: start with Payhip.

You don't need to spend money building a complicated ecommerce system when your products are essentially downloadable files. Payhip gives you the storefront, checkout, file delivery, coupons, bundles and pay-what-you-want pricing without a monthly bill. Payhip Payhip Help Center

Then, if sales grow substantially, you can reassess whether moving to a self-hosted WordPress/WooCommerce setup makes economic sense.

One important consideration for a nonprofit is donations vs. purchases: I'd keep your actual charitable donations separate from the ecommerce checkout unless your payment processor/platform explicitly supports the arrangement. Payhip, for example, notes that its pay-what-you-want functionality is intended for products, rather than simply accepting an unrestricted donation. Payhip Help Center

If you tell me roughly (1) how many PDFs you sell, (2) your average price, (3) monthly sales volume, and (4) whether you already have a WordPress website, I can calculate which option would cost your nonprofit the least per year.

For a nonprofit selling PDFs, workbooks, guides, and training materials, I’d strongly favor a WordPress-based solution rather than Shopify or a fully hosted ecommerce platform. You can keep the fixed costs very low and retain ownership of your store and customer data.

My top pick: WooCommerce

woocommerce.com would probably be my recommendation if you already have—or are willing to use—WordPress.

Why it fits:

• Free and open source. WooCommerce itself costs nothing; you mainly pay for hosting and payment-processing fees. WooCommerce WooCommerce
• Excellent for PDFs and digital downloads. You can set download limits, expiration dates, and protected download links. WooCommerce WooCommerce
• No platform transaction fee. You pay your payment processor (Stripe, PayPal, etc.), rather than an additional WooCommerce percentage. WooCommerce
• You can sell free and paid materials from the same store.
• You can eventually add donations, memberships, subscriptions, courses, physical merchandise, or event registrations without replacing the whole system.
• There's a huge WordPress ecosystem, so you're less likely to get locked into one vendor.

For a small nonprofit, I'd start with the free WooCommerce core and as few paid plugins as possible.

An even more focused alternative: Easy Digital Downloads

easydigitaldownloads.com is worth considering if almost everything you sell is digital.

It's specifically designed for digital products—including PDFs—and its free Lite version is available through WordPress.org. It supports unlimited products and transactions. Easy Digital Downloads Easy Digital Downloads

I'd choose EDD over WooCommerce if your store is essentially:

PDF → checkout → automatic download → customer email

WooCommerce is more attractive if you expect the nonprofit's ecommerce operation to grow into other types of commerce.

What I'd do on a tight budget

Rough philosophy: spend your money on reliable hosting, backups, security, and payment processing—not on an expensive ecommerce subscription.

One particularly useful feature for a nonprofit is that WooCommerce can handle free downloads as well as paid products, and there are options for collecting an email address before someone downloads a free resource. WooCommerce

One important caveat

Don't simply upload your PDFs to the normal WordPress Media Library and put public links on your site. For paid materials, use WooCommerce's downloadable-product mechanism so access can be controlled and download activity tracked. WooCommerce provides settings specifically for protected downloads, download limits, expiration, and unique download URLs. WooCommerce WooCommerce

Bottom line:
WooCommerce + WordPress is my #1 choice for your situation. If you are 100% digital and don't anticipate selling anything besides downloadable materials, I'd seriously consider Easy Digital Downloads Lite instead.

If you tell me roughly how many PDFs you sell, your monthly sales volume, whether you already have WordPress, and whether you need donations/memberships, I can give you a very specific $0–$30/month nonprofit stack and explain exactly what I'd install.

For a nonprofit selling PDFs, guides, curricula, and training materials, I would avoid a full retail ecommerce system unless you also sell physical goods. You mainly need:

• secure digital file delivery
• simple checkout
• discount codes / bundles
• donor or member pricing (if relevant)
• low monthly costs
• ownership of customer data

My recommendations, roughly in order:

1. WordPress + Easy Digital Downloads (best overall for most nonprofits)

easydigitaldownloads.com

Best if you already have (or can build) a WordPress website.

Pros:

• Designed specifically for digital products (PDFs, ebooks, downloads)
• Automatic delivery after payment
• Lots of nonprofit-friendly integrations
• You own your website and customer list
• Free core plugin; paid extensions are optional Easy Digital Downloads

Typical budget:

• Hosting: ~$5–15/month
• Domain: ~$10–20/year
• Payment processing: Stripe/PayPal fees only
• Plugin cost: can start at $0

Good setup:

• WordPress
• Easy Digital Downloads
• Stripe payments
• Mailchimp/Brevo for email follow-up
• Cloud storage (optional) for large files

This is probably my top pick for a small nonprofit that expects to grow.

2. WooCommerce + WordPress (best if you may expand)

woocommerce.com

Pros:

• Free and open source
• Huge ecosystem
• Can sell PDFs now and add physical merchandise later
• Supports memberships, subscriptions, donations, events, etc.

Cons:

• More complicated than you need for PDFs alone
• More plugins can mean more maintenance

Choose this if you think you may eventually sell:

• books
• event tickets
• merchandise
• memberships
• training subscriptions

3. Zeffy (best if you want nonprofit simplicity and near-zero cost)

zeffy.com

Zeffy is built specifically for nonprofits and offers online stores with no platform fees, funded through optional contributions from users. Zeffy

Pros:

• Very easy setup
• Nonprofit-focused
• Good for organizations without technical staff
• Can combine fundraising and sales

Cons:

• Less customizable than running your own store
• Less control over the storefront experience

This is a strong option if your priority is "get selling this month."

4. Open-source/self-hosted options (lowest software cost, more technical)

If you have someone comfortable managing a server:

• cubecart.com — open-source ecommerce platform that can be self-hosted. CubeCart
• Custom lightweight digital-download stores can also be built with open-source templates/tools. GitHub GitHub

Pros:

• Maximum control
• No SaaS subscription

Cons:

• You become responsible for: - security updates
• backups
• email delivery
• payment integrations

For most nonprofits, this is only worthwhile if you already have technical capacity.

5. If training is the main product: Moodle + ecommerce

If your PDFs are part of a broader training program (courses, certifications, quizzes), consider:

Moodle + an ecommerce plugin.

For example, open-source Moodle ecommerce extensions can connect course enrollment, payments, and digital products. ModernCommerce

Better for:

• paid courses
• certificates
• member learning portals

Overkill for just selling PDFs.

My suggested stack for a small nonprofit

Lowest-cost professional setup:

• Website: WordPress
• Store: Easy Digital Downloads
• Payments: Stripe
• Email: Brevo (free tier) or Mailchimp
• Files: protected downloads through your ecommerce plugin
• Donations: add a donation plugin or Zeffy link

Expected ongoing cost:

• ~$5–20/month plus payment processing

A few nonprofit-specific features I would prioritize

• Pay-what-you-can pricing (works well for mission-driven materials)
• Bulk licensing (schools, agencies, partner organizations)
• Discount codes for members
• Free downloads in exchange for email signup
• Automatic receipts for accounting
• Accessible PDFs (tagged PDFs, screen-reader friendly)

If you tell me:

1. whether you already have a website (WordPress, Wix, Squarespace, etc.),
2. approximate number of PDFs/products, and
3. whether buyers are mostly individuals or organizations,

I can narrow this to a specific setup.

For a nonprofit selling PDFs, guides, curricula, and training materials, I would avoid a general ecommerce platform unless you also sell physical goods. You mainly need:

• secure digital delivery
• simple checkout
• low/no monthly cost
• donation support
• discount codes or bundles
• email receipts
• minimal maintenance

My top recommendations:

1. WordPress + Easy Digital Downloads (best overall fit)

Best if you already have (or can build) a WordPress website.

Easy Digital Downloads is designed specifically for selling downloadable products rather than physical inventory. It can handle PDFs, ebooks, training files, memberships, and recurring access. Easy Digital Downloads DEV.co

Typical setup:

• WordPress hosting: ~$5–15/month
• Easy Digital Downloads core: free
• Payment processing: Stripe/PayPal fees only
• Optional paid add-ons later (subscriptions, software licensing, advanced reporting)

Pros

• Very nonprofit-friendly
• You own your website and customer list
• Great for content libraries
• Easy for volunteers/staff to manage
• Can combine sales + donations

Cons

• You handle updates, backups, and security
• Some advanced features require paid extensions

My pick for most small nonprofits: this one.

2. WooCommerce + WordPress (best if you may expand)

WooCommerce is free and extremely flexible. It can sell digital downloads, but it is broader than you need. Open Source Groups

Choose this if you might later sell:

• printed manuals
• event tickets
• merchandise
• memberships
• donations with complex workflows

Pros

• Huge ecosystem
• Many nonprofit integrations
• Familiar to many web developers

Cons

• More setup complexity
• More plugins to maintain

For a PDF-only store, I would usually choose Easy Digital Downloads over WooCommerce.

3. Gumroad or similar hosted platforms (easiest, least technical)

A hosted digital-product platform can get you selling quickly without maintaining a website.

Pros

• No server management
• Fast setup
• Handles file delivery

Cons

• Less control
• Platform fees can matter when margins are thin
• Your storefront/customer relationship is less owned

Good if your organization has one person managing everything and very little technical capacity.

4. Drupal Commerce + file delivery (for larger organizations)

Drupal Commerce is powerful and can handle complex permissions, memberships, and content-heavy sites. Its file-selling extensions can provide controlled downloads. Drupal.org Drupal.org

I would only choose this if you already use Drupal or have technical support.

5. A very low-cost “starter stack”

For a small nonprofit on a tight budget, I would build:

• WordPress
• Easy Digital Downloads
• Stripe nonprofit account (if available in your region)
• Free/low-cost email service
• Cloud storage backups
• Simple donation plugin

You could realistically operate this for roughly $100–250/year plus payment processing, depending on hosting and optional features.

My recommendation by situation

A few questions would change the recommendation:

1. Do you already have a website (WordPress, Wix, Squarespace, Drupal, etc.)?
2. About how many products do you sell (5, 50, 500+)?
3. Do you need restricted training access (courses/login area), or just downloadable PDFs after purchase?

A few questions would change the recommendation:

1. Do you already have a website (WordPress, Wix, Squarespace, Drupal, etc.)?
2. About how many products do you sell (5, 50, 500+)?
3. Do you need restricted training access (courses/login area), or just downloadable PDFs after purchase?

For a nonprofit selling PDFs, guides, workbooks, and training materials, I’d prioritize low recurring cost, simple digital delivery, and the ability to accept donations/discounts—not a full retail platform.

My top pick: WooCommerce + WordPress

WooCommerce would be my default recommendation if you already have (or are willing to run) a WordPress website.

• Core WooCommerce is free and open source with no monthly platform fee or revenue share. WooCommerce WooCommerce
• It supports downloadable products, so customers can purchase a PDF and receive a download link.
• You control the website, customer data, and files rather than being locked into a hosted marketplace.
• You can start with inexpensive/shared WordPress hosting and add paid extensions only if you actually need them.
• It also gives you room to expand into memberships, courses, physical merchandise, donations, subscriptions, etc.

woocommerce.com

A realistic budget setup: WordPress + WooCommerce + a payment processor such as Stripe/PayPal + inexpensive hosting. WooCommerce itself currently lists no monthly subscription and no platform revenue share; hosting is the main recurring expense. WooCommerce

Even better for PDFs: Easy Digital Downloads

If you only sell digital material, I'd seriously consider Easy Digital Downloads instead.

It's specifically designed for digital products—including PDF documents—rather than adapting a physical-product shopping cart to digital goods. Easy Digital Downloads

There's a free Lite version, while paid plans currently start at $99.50/year. Easy Digital Downloads

easydigitaldownloads.com

For your situation, I'd compare them this way:

One option I'd consider if you want very little technical work

A hosted service can actually be cheaper in staff time, even if it costs more in monthly fees. If nobody at your nonprofit wants to maintain WordPress, updates, backups, security, etc., I'd look at a hosted digital-download service rather than automatically choosing open source.

For a tight-budget nonprofit, though, I'd probably start with:

WordPress + WooCommerce → inexpensive hosting → Stripe/PayPal → downloadable PDFs

and avoid paid plugins until you discover a specific problem you need to solve.

One important consideration: don't put your PDF files in a publicly guessable /uploads/ URL and assume the checkout protects them. Use the ecommerce system's controlled download mechanism so a customer can't simply share the direct file URL.

If you tell me roughly (1) how many PDFs you sell, (2) your monthly sales volume, (3) whether you already have WordPress, and (4) whether you need donations/subscriptions, I can recommend a specific $0–$20/month stack and estimate your payment/hosting costs.

If your nonprofit is selling mostly PDFs, workbooks, ebooks, and training materials, I’d avoid a full-blown Shopify-style setup unless you really need it.

My shortlist

🥇 My recommendation: Payhip

For a small nonprofit on a tight budget, I'd probably start with Payhip.

Its free plan is genuinely usable: $0/month, 5% transaction fee, unlimited products and unlimited revenue, with all features available on the free tier. You still pay Stripe/PayPal processing fees. Payhip Payhip

It supports PDFs and other digital files, including multiple files per product, and lets you offer free products and pay-what-you-want pricing—which could be particularly useful for a nonprofit. Payhip Help Center Payhip Help Center

I'd use it if: you want to get a storefront running quickly without having to maintain WordPress, plugins, security updates, backups, etc.

🥈 Best open-source choice: WooCommerce

If you already have a WordPress website, I'd seriously consider WooCommerce.

The core platform is free and open source, with no monthly subscription or revenue share. You pay for hosting and whatever extensions you actually need. WooCommerce

The downside is that you're responsible for more of the infrastructure. Hosting, backups, updates, security, payment configuration, and plugins can turn a "free" store into a maintenance project.

For a nonprofit with someone technically comfortable managing WordPress, though, it gives you much more ownership and flexibility than a hosted marketplace.

🥉 If you're exclusively digital: Easy Digital Downloads

Easy Digital Downloads (EDD) is particularly attractive if your WordPress site is essentially a digital-resource store. It's designed specifically around downloadable products rather than physical inventory. Easy Digital Downloads Hostinger

There's a free core version, while paid plans add things such as subscriptions, payment integrations, and other functionality. The current Personal plan is listed at $99.50/year, so I'd start with the free version rather than immediately buying a plan. Easy Digital Downloads

What I wouldn't choose first: Gumroad

Gumroad is extremely easy, and it handles digital delivery and tax obligations for you. But its current direct-sale fee is 10% + $0.50 per transaction, in addition to payment-processing costs; marketplace-discovery sales are 30%. Gumroad Gumroad

For a nonprofit selling inexpensive PDFs—for example, $5–$15 resources—that percentage can become painful.

What I'd do in your situation

I'd choose based on your existing website:

• No ecommerce yet → Payhip.
• Already using WordPress → WooCommerce or EDD.
• Technically capable and want maximum ownership → WooCommerce.
• WordPress + almost exclusively PDFs/downloads → EDD.
• Want zero technical maintenance → Payhip.

One particularly good nonprofit setup would be your existing website + Payhip checkout/store, rather than rebuilding your whole website around ecommerce.

If you tell me roughly how many PDFs/products you have, your average price, monthly sales volume, and whether you already use WordPress, I can compare the actual yearly cost of Payhip vs. WooCommerce vs. EDD for your nonprofit.

Its free plan is genuinely usable: $0/month, 5% transaction fee, unlimited products and unlimited revenue, with all features available on the free tier. You still pay Stripe/PayPal processing fees. Payhip Payhip

For a nonprofit selling inexpensive PDFs—for example, $5–$15 resources—that percentage can become painful.

What I'd do in your situation

I'd choose based on your existing website:

For a nonprofit selling PDFs, guides, workbooks, and training materials, I’d prioritize low fixed costs, easy digital delivery, and the ability to accept donations or “pay what you can.”

My recommendation

1. woocommerce.com + WordPress — best long-term value

This would be my first choice if you already have a WordPress website.

WooCommerce itself is open source/free, and its core supports downloadable products. You can set download limits/expiration, automatically email purchasers their download links, and keep download activity in your store's records. WooCommerce WooCommerce

Typical cost:

• WooCommerce: $0
• WordPress: $0
• Web hosting: roughly $5–15/month if you shop around
• Payment processing: usually the unavoidable Stripe/PayPal-type transaction fees
• Optional extensions: only if you need them

Why I like it for a nonprofit: you own the website and customer relationship rather than building your entire store on someone else's platform. It's also much easier to expand later into memberships, courses, physical merchandise, donations, coupons, etc.

Downside: there's more setup and maintenance than a hosted service.

2. gumroad.com — easiest if you want almost zero technical work

If your priority is "I need to start selling PDFs this week and don't want to manage a website," Gumroad is considerably easier.

There is no monthly fee, but the transaction fee is substantial: currently 10% + $0.50 per direct sale, with a 30% fee for sales through its Discover marketplace. Gumroad Gumroad

It handles digital delivery, and customers receive download links after purchasing. Gumroad It also supports pay-what-you-want pricing, which could be particularly useful for a nonprofit. Gumroad

I'd choose it if:

• You have only a handful of products.
• Your technical skills/time are limited.
• Sales volume is relatively low.
• You want to avoid paying for hosting.

The catch is that 10% + $0.50 gets expensive as your sales grow.

3. Easy Digital Downloads — worth considering for a PDF-heavy WordPress site

If you're already using WordPress and your store will consist almost entirely of digital products, I'd also look closely at Easy Digital Downloads (EDD).

It's purpose-built around digital products rather than being a general physical-goods ecommerce system. For an organization selling dozens or hundreds of PDFs, that focus can make more sense than installing a full ecommerce platform.

What I'd actually do in your situation

I'd use this decision rule:

A particularly cheap setup

If your nonprofit already has a WordPress site, I'd avoid paying for Shopify or another full hosted ecommerce platform.

I'd do:

WordPress → WooCommerce → Stripe/PayPal → PDF downloads

WooCommerce's core handles the downloadable files and can protect the download URLs, limit downloads, and expire links. WooCommerce WooCommerce

Then I'd add a "Support our nonprofit" option at checkout rather than trying to build a separate donation system immediately.

One important caveat: don't put your paid PDFs in a publicly accessible Google Drive/Dropbox folder and simply email the link after payment. Use the ecommerce platform's protected download mechanism so purchasers get individualized download access.

If you tell me roughly (1) how many PDFs you sell, (2) your average price, (3) monthly sales, and (4) whether you already have WordPress/another website, I can recommend the cheapest setup and estimate your monthly/annual cost.

For a nonprofit selling PDFs and training materials, I’d usually avoid a full ecommerce platform unless you need complex features. Your priorities are likely:

• very low monthly cost
• easy management by non-technical staff
• secure PDF delivery
• donation-friendly checkout
• ability to grow into courses/memberships later

Here are the options I’d consider:

1. WordPress + Easy Digital Downloads (best overall for most nonprofits)

Easy Digital Downloads is probably the strongest fit if you already have (or can build) a WordPress website. It is designed specifically for selling digital products like PDFs, guides, reports, and training materials. Easy Digital Downloads DEV.co

Typical cost:

• WordPress software: free
• Hosting: roughly £5–£15/month depending on provider
• Plugin: free core version; paid extensions optional

Pros

• You own your website and customer data
• Excellent for PDFs and downloadable resources
• Can add donations, memberships, newsletters, and courses
• Lots of nonprofit-friendly integrations

Cons

• Requires keeping WordPress/plugins updated
• Some advanced payment or membership features may require paid add-ons

Best for: A nonprofit that wants a long-term website + shop in one place.

2. WooCommerce + WordPress (best if you may sell physical items later)

WooCommerce is free and very popular, but it is more general-purpose than you need. It can sell digital downloads, subscriptions, donations, event tickets, and physical merchandise.

Pros

• Huge ecosystem
• Many payment options
• Good if you might add books, merchandise, or memberships

Cons

• More setup complexity than a digital-only store
• Can become plugin-heavy

Best for: Nonprofits planning a broader online shop.

3. Gumroad-style hosted platforms (lowest effort)

If you only sell a handful of PDFs, a hosted service may be cheaper in staff time than self-hosting.

Examples:

• Gumroad
• Payhip

Pros

• No server maintenance
• Upload PDF → create product → share link
• Automatic delivery

Cons

• Transaction fees
• Less control over branding and supporter data

Best for: A small catalogue and a volunteer-run team.

4. Open-source self-hosted options (lowest software cost, more technical)

If you have someone comfortable managing servers:

• Zipsell — focused on selling digital downloads with secure delivery. GitHub
• Spree Commerce — powerful but aimed more at developers and larger stores. Spree Commerce

Pros

• Maximum control
• No platform subscription fees

Cons

• You become responsible for hosting, updates, security, backups

Best for: Organisations with technical volunteers or IT support.

5. If your “training materials” become courses

If you move from PDFs into structured training (videos, quizzes, certificates, learner accounts), consider a learning management system:

• Moodle + ecommerce extensions can support course sales and enrolment workflows. ModernCommerce

My recommendation for a tight-budget nonprofit

I would choose:

Small catalogue (under ~50 PDFs):

WordPress + Easy Digital Downloads

Very small operation (1–10 products, no technical help):

Payhip/Gumroad-style hosted store

Existing WordPress nonprofit website:

Add Easy Digital Downloads rather than creating a separate store

Technical nonprofit with developer support:

Self-hosted open-source solution

A practical low-cost stack could be:

• WordPress website
• Easy Digital Downloads
• Stripe or PayPal payments
• MailerLite/Brevo for supporter emails
• Cloud storage backups

That keeps ongoing costs low while letting you sell resources, collect donations, and build a supporter database. Easy Digital Downloads

If you tell me (1) how many PDFs you sell, (2) whether you already have a website, and (3) whether buyers need accounts/certificates, I can narrow it down to a specific setup.

Technical nonprofit with developer support:

Self-hosted open-source solution

For a nonprofit selling mostly PDFs, ebooks, training materials, and other digital downloads, I’d narrow it to two choices:

My recommendation

1. payhip.com — best if you want the cheapest/easiest setup

This is probably where I’d start if your budget and staff time are both tight.

• $0/month on the Free plan.
• Payhip takes 5% per sale, plus normal Stripe/PayPal processing fees.
• Unlimited products and unlimited revenue even on the free plan.
• Handles digital file delivery, checkout, coupons, pay-what-you-want pricing, and other marketing features.
• You don't have to maintain WordPress, hosting, security updates, backups, or ecommerce plugins.
• Payhip explicitly offers charity discounts, so it's worth contacting them as a nonprofit. Payhip Payhip

For example, on a $20 PDF, the Payhip fee is $1 before payment-processing fees. That's a pretty reasonable tradeoff if it saves you hours of technical maintenance.

payhip.com

2. woocommerce.com — best if you already have WordPress

If your nonprofit already has a WordPress website and someone comfortable maintaining it, I'd seriously consider WooCommerce.

WooCommerce itself is free and open source, with no platform revenue share. You pay for hosting and whatever optional extensions you need. It supports digital downloads as well as physical products, subscriptions, memberships, etc. WooCommerce WooCommerce

The downside is that "free" doesn't necessarily mean cheap in staff time. You'll be responsible for hosting, WordPress/WooCommerce updates, backups, security, troubleshooting, and potentially paid extensions.

woocommerce.com

What I'd choose for your situation

My practical recommendation: Start with Payhip unless you already have a well-maintained WordPress site. The 5% transaction fee is likely worth it for a resource-constrained nonprofit because you aren't committing scarce staff time to running an ecommerce system.

One useful wrinkle: Payhip supports free products and email collection, so you could use free PDFs as lead magnets while selling premium training materials alongside them. Payhip Help Center

If you tell me roughly how many PDFs you sell, your average monthly sales ($), whether you already have WordPress, and whether you need memberships/courses, I can calculate which option would actually cost your nonprofit the least.

For a nonprofit selling PDFs, training materials, and other digital downloads on a tight budget, I’d narrow it to two choices:

My recommendation

1. Payhip — best if you want the cheapest/easiest setup

payhip.com is probably where I’d start if you don’t already have a WordPress site or don't want to maintain software.

• $0/month on its Free Forever plan.
• Takes 5% per transaction, plus the normal Stripe/PayPal processing fee. Payhip Payhip
• Unlimited products and unlimited revenue even on the free plan.
• Handles file delivery automatically after purchase.
• Supports PDFs and multiple files, with files up to 5 GB. Payhip Payhip Help Center
• Supports pay-what-you-want pricing, which is particularly useful for nonprofits. For example, you can set a $10 minimum and let supporters pay $10, $15, $25, etc. Payhip Help Center
• Payhip says it offers charity discounts, so I'd contact them about your nonprofit status. Payhip

The big advantage is that you don't have to worry about hosting, download security, updates, backups, or configuring a payment system.

For a small nonprofit, I'd seriously consider this the default choice.

2. WooCommerce — best if you already use WordPress

woocommerce.com is my choice if you already have a WordPress website and are comfortable maintaining it.

WooCommerce itself is free and open source, with no monthly subscription and no revenue share. WooCommerce WooCommerce It natively supports downloadable products, including controls for how customers receive their files. WooCommerce

That means your basic stack could be:

WordPress → WooCommerce → Stripe/PayPal → PDF download

Your main costs would be hosting and payment-processing fees. WooCommerce currently estimates typical hosting at roughly $25–$350/month, although a very small nonprofit store can potentially operate below that depending on the host and setup. WooCommerce

The upside is ownership and flexibility: your website, customer data, products, and store aren't locked into a SaaS platform.

The downside is that you're responsible for WordPress/WooCommerce updates, backups, security, and troubleshooting.

What I'd choose for your situation

One other option: Easy Digital Downloads

If you're already on WordPress and almost everything you sell is digital, I'd also look at easydigitaldownloads.com. It's specifically designed around digital products rather than physical merchandise. Edd Sell Services Easy Digital Downloads

I'd rank it:

Payhip → easiest/lowest maintenance
WooCommerce → best open-source/value option
Easy Digital Downloads → best WordPress-centric digital-download specialist

For a tight-budget nonprofit, I wouldn't start with Shopify, BigCommerce, or a complicated self-hosted ecommerce stack unless you have a specific need they solve.

If you tell me roughly how many PDFs you sell, your monthly sales volume, whether you already have WordPress, and whether you need memberships/courses or just one-time downloads, I can recommend the cheapest setup—including the payment processor and approximate monthly cost.

For a nonprofit selling PDFs, guides, toolkits, and training materials, I would avoid a full-blown ecommerce platform unless you need a lot of complexity. Your main needs are usually:

• secure file delivery after payment
• discount codes / free resources
• donor or supporter data ownership
• low monthly costs
• easy volunteer/staff administration
• ability to bundle PDFs with training access later

My recommendations, roughly in order:

1. WordPress + Easy Digital Downloads (best overall for nonprofits)

Best if you already have (or want) a WordPress website.

Easy Digital Downloads is built specifically for selling digital products: PDFs, ebooks, downloads, memberships, and similar resources. easydigitaldownloads.com

Pros

• Very nonprofit-friendly
• You own your website and customer list
• No marketplace percentage taken from each sale
• Lots of payment options
• Good for growing from PDFs → courses → memberships

Costs

• WordPress software: free
• Hosting: often ~$5–15/month
• Plugin costs vary (you can start simple)

Typical setup

• WordPress site
• Easy Digital Downloads
• Stripe or PayPal
• A low-cost email tool for supporters

This would be my default choice for a small nonprofit.

2. Zeffy (best if fundraising is a major part of the mission)

Zeffy offers nonprofit-focused ecommerce and fundraising tools with a no-platform-fee model supported by optional donor contributions. www.zeffy.com

Good fit if you sell materials as part of fundraising, for example:

• training manuals
• advocacy toolkits
• event materials
• educational resources

Pros

• Designed for nonprofits
• Very low cost
• Donation + sales workflows together

Possible downside

• Less customizable than owning your own WordPress store

3. Payhip (best "just get selling this week" option)

Payhip is a simple hosted store for digital downloads.

Pros

• No technical maintenance
• Upload PDF → create product → share link
• Handles digital delivery
• Good for a small catalog

Cons

• Less control over branding/data than your own site
• Transaction fees may matter as sales grow

4. WooCommerce + WordPress (best if you want a full store)

WooCommerce is the most flexible open-source ecommerce option.

Pros

• Extremely customizable
• Huge ecosystem
• Can sell PDFs, memberships, courses, physical items

Cons

• More maintenance than Easy Digital Downloads
• More plugins = more things to manage

For a nonprofit selling only digital materials, I usually prefer Easy Digital Downloads over WooCommerce.

5. Fully open-source/self-hosted options (only if you have technical help)

If you have a developer volunteer:

• Spree Commerce — powerful open-source commerce framework with support for digital products, but probably overkill for a small nonprofit. spreecommerce.org
• TishCommerce GitHub repository — lightweight open-source digital download store aimed at selling virtual products. github.com

These save subscription costs but increase your maintenance burden.

What I would choose for your situation

If you already have a website:

WordPress + Easy Digital Downloads + Stripe

If you have no website and want the fastest launch:

Payhip or Zeffy

If you expect to build a training library later:

WordPress + Easy Digital Downloads now, then add an LMS/membership system later

A few questions would change the recommendation:

1. Do you already have a website (WordPress, Wix, Squarespace, etc.)?
2. Are these mostly one-time PDF purchases, or do you want courses/memberships/subscriptions?
3. Roughly how many products and sales per month (e.g., 10 vs. 1,000)?

For a nonprofit selling mostly PDFs, ebooks, workbooks, and training materials, I’d prioritize low transaction costs, automatic file delivery, coupons/discounts, and the ability to accept donations or “pay what you can.”

My top pick: WooCommerce + WordPress

WooCommerce is probably the best fit if you already have a WordPress site. The core software is free and open source, has no monthly platform fee or revenue share, and supports digital downloads. You pay your payment processor and hosting costs instead. woocommerce.comeasydigitaldownloads.com

WooCommerce official site

Why I'd choose it for you:

• $0 for the ecommerce software
• Automatic delivery of PDFs after purchase
• Stripe/PayPal and other payment processors
• Coupons and discounted nonprofit pricing
• Can sell bundles of training materials
• Can add donations alongside purchases
• You own the site and customer/order data
• Huge WordPress ecosystem, so you're less locked in
• Can start very small and add functionality later

The main downside is that you have to maintain WordPress, hosting, backups, and plugins. WooCommerce itself estimates typical hosting at roughly $25–$350/month, although a very small nonprofit store can often operate below the low end of that range with inexpensive hosting. woocommerce.com

If you're only selling digital files: Easy Digital Downloads

Easy Digital Downloads is worth serious consideration. It's designed specifically around digital products rather than physical merchandise. Its product workflow lets you upload files, set prices, create bundles, and provide downloads after purchase. easydigitaldownloads.com

Easy Digital Downloads official site

I'd pick EDD over WooCommerce if your catalog will remain something like:

PDF → workbook → video course → training package → downloadable resources

rather than eventually becoming a broader merchandise store.

If you want the absolute simplest setup

A hosted service such as Payhip can be easier because you don't have to maintain WordPress or plugins. The tradeoff is that hosted platforms generally take a larger cut or put useful features behind paid plans.

For a nonprofit on a tight budget, I'd generally rather put that money into hosting + payment processing and retain ownership of the store.

What I'd actually build

If I were setting this up for a small nonprofit, my starting stack would be:

You can keep the initial technology surprisingly lean. WooCommerce's core has unlimited products and orders, and doesn't charge a percentage of your sales itself. woocommerce.com

One particularly useful nonprofit feature: you could offer something like “$15 / $25 / $50 — pay what you can” for selected resources. WooCommerce has extensions that support customer-entered pricing, including nonprofit/donation-style use cases. woocommerce.com

My ranking for your situation

1. 🥇 WooCommerce + WordPress — best combination of cost, ownership, flexibility, and nonprofit friendliness.
2. 🥈 Easy Digital Downloads + WordPress — potentially better if you're exclusively a digital-download operation.
3. 🥉 Payhip or similar hosted service — best if you value simplicity more than minimizing ongoing fees.
4. Shopify — excellent software, but I'd generally avoid the recurring platform cost for a cash-strapped nonprofit whose products are mostly PDFs.

If you tell me (1) roughly how many PDFs/products you have, (2) your approximate monthly sales, (3) whether you already have WordPress, and (4) whether you need donations/memberships, I can recommend the cheapest practical stack and estimate your monthly + per-sale costs.

For a nonprofit selling mostly PDFs, ebooks, workbooks, and training materials, I’d avoid building a complicated ecommerce stack unless you really need the control.

My shortlist:

1. My recommendation: Payhip

For a small nonprofit, Payhip is probably the sweet spot. Its free plan is $0/month with a 5% transaction fee, unlimited products, and unlimited revenue. Stripe/PayPal processing fees are additional. Payhip Payhip

It supports digital downloads, courses, memberships, coupons, and even pay-what-you-want pricing, which could be particularly useful for a nonprofit. Payhip Payhip Help Center

So you could have:

Training Manual — $15
Volunteer Handbook — $10
Complete Training Bundle — $35
Support our mission + get the PDF — $10+

There's also no need to pay for hosting, security, WordPress maintenance, or ecommerce plugins.

One interesting point: Payhip says it offers charity discounts, so I'd actually contact them before accepting the standard 5% rate. Payhip

2. If you want truly open source: WooCommerce

If you already have a WordPress website and someone on your team can handle basic technical maintenance, woocommerce.com is the route I'd take.

The core platform is free/open source with no platform revenue share. You pay for hosting and any extensions you choose. WooCommerce

For PDFs, you can keep the setup quite lean:

WordPress → WooCommerce → Stripe/PayPal → PDF download

The downside is that the "free" software doesn't mean zero cost. You'll have hosting, backups, security updates, email delivery, and potentially paid extensions to deal with.

3. Easy Digital Downloads

If you're already a WordPress shop, I'd also consider easydigitaldownloads.com.

It's specifically designed around digital products rather than physical inventory, shipping, etc. That's a better conceptual fit for a PDF/training-material nonprofit than a traditional store. Hostinger Kinsta®

I'd pick EDD over WooCommerce if everything you sell is digital and you expect the store to become a significant part of your operation.

4. Gumroad

gumroad.com is extremely easy, and it can handle digital products, courses, memberships, and pay-what-you-want products. Gumroad Gumroad

But its direct-sale fee is currently 10% + $0.50 per transaction, on top of payment processing in some cases. Gumroad

For a nonprofit operating on thin margins, that can become painful.

What I'd do in your situation

Start with Payhip. You can get a store running without spending anything upfront, test whether people actually buy the materials, and avoid creating an IT project for your nonprofit.

If sales eventually become substantial enough that the transaction fees are significant, move to WooCommerce/EDD on your own WordPress site.

For example, if you're doing $2,000/month in sales, Payhip's 5% platform fee alone is about $100/month. At that point, owning the ecommerce infrastructure may start making economic sense.

If you tell me (1) whether you already have a WordPress/website, (2) roughly how many PDFs you sell, and (3) your approximate monthly sales, I can recommend the cheapest setup—including payment processing, hosting, download protection, tax handling, and nonprofit/donation functionality.

For a nonprofit selling PDFs, guides, and training materials, I’d narrow it to two choices:

My top pick: Payhip

Payhip is probably the best fit if your priority is getting up and running cheaply with almost no technical work.

• $0/month on the free plan
• 5% Payhip transaction fee, plus Stripe/PayPal processing
• Unlimited products and revenue on the free tier
• Handles digital file delivery automatically
• Supports coupons, memberships, courses, and pay-what-you-want pricing
• Payhip explicitly offers charity discounts, so I'd contact them about your nonprofit status. payhip.com
• It can support a model like "$10 minimum, pay more if you'd like," which can be particularly useful for nonprofit materials. help.payhip.com

I'd choose Payhip if you're selling perhaps 5–100 PDFs/training products and don't want someone on your team maintaining a website.

Best open-source option: WooCommerce

WooCommerce is my recommendation if you already have WordPress or want maximum ownership and control.

WooCommerce itself is free and open source, has no platform revenue share, and supports downloadable products. You pay for hosting and any premium extensions you choose, plus payment processing. woocommerce.com

The downside is that you become responsible for more of the technology—WordPress updates, backups, security, hosting, plugins, etc. That's worthwhile if you already have a WordPress site, but probably not worth the administrative burden if you're starting from scratch.

What I'd avoid on a tight nonprofit budget

Gumroad is wonderfully simple, but its current direct-sale fee is 10% + $0.50 per transaction, before payment-processing costs. gumroad.com That's a substantial cut for a nonprofit.

My practical ranking

One important consideration: if your nonprofit already has a WordPress website, tell me that. In that case, I may recommend WooCommerce or Easy Digital Downloads instead of Payhip, because you can integrate the store directly into your existing site.

If you tell me roughly (1) your monthly sales volume, (2) average PDF price, (3) whether you already use WordPress, and (4) whether you need subscriptions/courses, I can give you a very specific lowest-cost setup and estimate the fees.

For a nonprofit selling PDFs, guides, courses, and training materials, I’d prioritize low upfront cost, low maintenance, automatic file delivery, and the ability to accept discounts or “pay what you can” pricing.

My top picks

1. Payhip — what I'd probably choose

Payhip has a $0/month plan with a 5% transaction fee, unlimited products, and unlimited revenue. It specifically supports PDFs and other digital downloads, with customers receiving download links after purchase. payhip.com

That's particularly attractive for a small nonprofit because you don't have to pay for hosting, security, updates, or a developer.

It also supports pay-what-you-want pricing, which could be useful for nonprofit training materials—for example, $10+ for a workbook or 0+ for a resource you want to make freely available while allowing supporters to contribute. help.payhip.com

I'd start here if: you want to be selling within a day or two and don't have someone technical maintaining a website.

2. WooCommerce — best if you want true open source

WooCommerce is open source and its core platform is free, with no platform revenue share. You pay for WordPress hosting and whatever extensions you actually need. woocommerce.com

For a nonprofit that already has a WordPress website, this can be an excellent long-term solution. You can sell downloadable PDFs directly from your existing site and retain much more control over your customer data and storefront.

The downside is maintenance. You'll be responsible for WordPress, plugins, backups, security, updates, payment configuration, etc. Hosting and extensions can also turn "free" into a meaningful annual expense. woocommerce.com

I'd choose this if: you already have WordPress and someone comfortable administering it.

3. Gumroad — easiest alternative

Gumroad is extremely easy for selling PDFs, ebooks, courses, and memberships. There is no monthly fee, but direct sales currently cost 10% + $0.50 per transaction, and marketplace-discovery sales are 30%. gumroad.com

One interesting advantage for a nonprofit is that Gumroad can handle sales-tax obligations as the merchant of record. help.payhip.comwoocommerce.comgumroad.com

I'd generally pick Payhip over it for your situation because the 5% free-plan fee is substantially lower.

What I'd do in your shoes

If your budget is extremely tight:

Existing website → Payhip storefront → Stripe/PayPal → PDFs delivered automatically

You could start with $0/month platform cost, validate whether people actually buy the materials, and only move to a self-hosted solution later if you need more control.

If you already run WordPress, I'd instead seriously consider WooCommerce, particularly if you expect the store to become a significant part of the nonprofit's operations.

One other thing I'd investigate before choosing: nonprofit pricing/discounts. Payhip explicitly says it offers charity discounts, so it's worth contacting them before signing up. payhip.com

If you tell me roughly (1) how many PDFs/products you have, (2) expected monthly sales, (3) whether you already have a WordPress website, and (4) whether you need memberships/courses, I can recommend the cheapest setup and estimate your monthly/annual cost.

For a nonprofit selling PDFs, workbooks, courses, and training materials, I’d narrow it to three options:

My recommendation: Payhip to start

If you're really watching every dollar and don't have someone technical maintaining a website, I'd start with Payhip's free plan. It has unlimited products and revenue, supports PDFs and other files up to 5 GB, and lets you use pay-what-you-want pricing—which could be particularly useful for a nonprofit. The free plan takes 5% per transaction, in addition to Stripe/PayPal processing fees. Payhip also says it offers charity discounts, so I'd specifically ask them about that. payhip.com

Payhip pricing

If you already have WordPress: WooCommerce

I'd choose WooCommerce if your nonprofit already has a WordPress website and you're comfortable maintaining it. WooCommerce itself is free and open source, has no revenue share, and supports downloadable products. You control the store and data rather than being locked into a hosted marketplace. woocommerce.com

The catch is that "free" doesn't mean zero cost: you'll need hosting, payment processing, and potentially paid extensions. For a technically capable nonprofit, though, it can be the cheapest option over the long run.

WooCommerce download

Why I wouldn't make Gumroad my first choice

Gumroad is exceptionally easy and handles tax obligations as a merchant of record, which is valuable if you sell internationally. But its direct-sale fee is 10% + $0.50, plus payment-processing costs, so that can eat noticeably into nonprofit revenue. gumroad.com

For example, on a $20 PDF, a 10% platform fee alone is $2, before the other processing costs.

One important wrinkle: if your "training materials" include paid courses, memberships, recurring subscriptions, or certificates, I'd evaluate the platforms differently. And if you already have a WordPress site, I'd strongly lean toward WooCommerce rather than starting a separate storefront.

If you tell me roughly (1) how many PDFs/products you have, (2) average price, (3) whether you already use WordPress, and (4) whether you need courses/memberships, I can recommend a specific setup and estimate your annual cost at $5k, $10k, and $25k in sales.

For a nonprofit selling mostly PDFs, ebooks, training materials, and other digital downloads, I’d keep the stack simple and avoid paying for a full SaaS ecommerce platform unless you really need its convenience.

My recommendation

1. WooCommerce + WordPress — best overall for a tight budget

WooCommerce is free and open source, with no monthly platform fee or revenue share. It supports downloadable products natively, and you can choose inexpensive hosting and your own payment processor. woocommerce.com

Typical setup:

• WordPress — free/open source
• WooCommerce — free
• Low-cost WordPress hosting — roughly $5–15/month if you shop carefully
• Stripe/PayPal — pay normal payment-processing fees
• Your PDFs — delivered automatically after purchase

Why I'd choose it for you: You own the site and customer data, and you aren't giving up 10% of every small PDF sale to the ecommerce platform.

2. Easy Digital Downloads — potentially even better if everything is digital

Easy Digital Downloads is a WordPress ecommerce system specifically designed around digital products rather than physical merchandise. Its free "Lite" version is available, while paid plans add things like subscriptions, discounts, reporting, and additional payment functionality. easydigitaldownloads.com

I'd favor EDD over WooCommerce if you have:

• 100% digital products
• lots of PDFs
• downloadable training packages
• recurring memberships/subscriptions
• no need for shipping, physical inventory, etc.

It's more purpose-built for your situation.

3. Gumroad — easiest, but expensive as you grow

Gumroad is probably the easiest option if you don't want to maintain WordPress.

There is no monthly fee, but direct sales currently carry a 10% + $0.50 transaction fee, plus payment-processing costs. Gumroad also handles sales-tax obligations as merchant of record, which is a significant administrative advantage. gumroad.com

For example, on a $10 PDF, the 10% + $0.50 fee alone is $1.50 before the additional processing component.

That's attractive when you're doing very few sales, but painful if you're selling thousands of dollars of material every month.

What I'd do in your shoes

My pick: Easy Digital Downloads + WordPress if your catalog is almost entirely PDFs and training materials.

My pick: WooCommerce + WordPress if you want maximum flexibility, might eventually sell physical items, or already have a WordPress website.

One additional consideration for a nonprofit: don't overlook payment processing and donation functionality. The cheapest ecommerce platform isn't necessarily the cheapest overall if you also need donations, donor records, tax receipts, memberships, etc.

If you tell me roughly (a) how many PDFs you sell, (b) average price, (c) monthly sales volume, and (d) whether you already have a WordPress website, I can recommend a specific $0–$20/month stack and estimate your actual annual cost.

For a nonprofit selling mostly PDFs, downloadable training materials, and possibly courses, I’d prioritize low recurring cost, automatic file delivery, simple checkout, and nonprofit/donation support.

My recommendation: WordPress + Easy Digital Downloads

If you already have a WordPress website—or are comfortable maintaining one—Easy Digital Downloads (EDD) is probably the best fit. It was built specifically around digital products rather than physical inventory, so it fits PDFs, ebooks, training files, bundles, and similar materials particularly well. eddsellservices.com

Why I’d choose it:

• Open-source WordPress foundation
• Designed specifically for downloadable products
• No need to pay for physical-product features you don't need
• Can grow into memberships, subscriptions, discount codes, bundles, etc.
• You control your website and customer data more than with a hosted marketplace
• Potentially very inexpensive if you already have hosting

The tradeoff is that you have to maintain WordPress, plugins, backups, security, and updates. For a tiny nonprofit without technical help, that maintenance burden can outweigh the savings.

Best low-maintenance alternative: Ecwid

If you want something that staff/volunteers can operate without dealing with WordPress administration, I'd seriously consider Ecwid.

Ecwid supports automatic delivery of downloadable products, including PDFs, with unique download links after purchase. Digital products are available starting with its Venture plan. support.ecwid.com

More importantly for you, Ecwid currently advertises six months of Venture free for nonprofits. Its current Venture pricing is $35/month or $29/month when paid annually after that period. www.ecwid.comgivewp.com

It also has zero Ecwid transaction fees, although your payment processor (such as Stripe or PayPal) will still charge its normal processing fees. www.ecwid.comgivewp.com

I'd choose based on your situation

For donations, GiveWP is worth considering alongside WordPress. Its core plugin is free, with paid add-ons for additional functionality; its free tier supports Stripe and PayPal. givewp.com

One setup I'd particularly recommend

If I were setting this up for a budget-conscious nonprofit, I'd aim for:

WordPress → Easy Digital Downloads → Stripe/PayPal → your existing domain

Then organize the store into:

• Free resources
• Individual PDFs
• Training bundles
• Full training courses/materials
• "Pay what you can" resources
• Donations

That gives you a fairly professional storefront without locking the nonprofit into a high monthly SaaS bill.

One caveat: if your PDFs are proprietary training materials, I'd also think about download security, expiring links, refunds, and whether purchasers should be allowed to share files. That's an area where the choice between EDD and a hosted service matters.

If you tell me (1) roughly how many PDFs you sell, (2) your approximate monthly sales, (3) whether you already have WordPress, and (4) whether you need donations/memberships, I can narrow this down to the cheapest practical setup and estimate the annual cost.

For a nonprofit selling mostly PDFs, guides, workbooks, and training materials, I’d narrow it to two choices:

1. My recommendation: Payhip if you want to get selling quickly

Payhip has a $0/month plan, unlimited products, and all features; it takes 5% per transaction, in addition to Stripe/PayPal processing fees. payhip.com

That's particularly attractive for a small nonprofit because you don't have to pay for hosting, security, updates, payment integration, or complicated ecommerce software.

It also supports digital downloads, free products, courses, bundles, memberships, coupons, and pay-what-you-want pricing. payhip.com

Example: If you sell $1,000/month, the Payhip platform fee is $50. That's often cheaper than paying someone to maintain a self-hosted ecommerce site.

And Payhip specifically says it offers charity discounts, so I'd contact them and ask what they can offer a nonprofit. payhip.compayhip.comeasydigitaldownloads.com

2. If you already have WordPress: WooCommerce

If your nonprofit already has a WordPress website, I'd seriously consider WooCommerce.

WooCommerce is free and open source, has no monthly platform fee and no revenue share, and supports digital downloads. You pay your hosting and payment processor rather than a percentage to WooCommerce. woocommerce.com

That's potentially much cheaper as your sales volume grows.

A simple stack could be:

WordPress → WooCommerce → Stripe/PayPal → downloadable PDFs

The downside is that you are responsible for hosting, updates, backups, security, and troubleshooting. Paid extensions can also add up. WooCommerce currently estimates typical hosting at roughly $25–$350/month, although a small nonprofit can often find cheaper hosting than that. woocommerce.com

3. Easy Digital Downloads

If your site is already WordPress and almost everything you sell is digital, I'd also look at Easy Digital Downloads (EDD). It's specifically designed around digital products including PDFs, rather than physical inventory. easydigitaldownloads.com

It's a good product, but I'd put it behind WooCommerce for a tight-budget nonprofit because some of the more useful functionality is in paid plans/add-ons.

What I'd do in your situation

If you're starting from scratch:
→ Payhip

If you already have WordPress:
→ WooCommerce

If you expect to grow into a substantial digital-resource library:
→ WooCommerce or EDD, so you own the underlying store and aren't paying a percentage of every sale.

One important nonprofit-specific consideration: don't optimize only for the lowest monthly cost. Payment processing, automatic delivery of PDFs, tax handling, donation/pay-what-you-want options, discount codes, customer emails, and accessibility can matter more than saving $10/month.

If you tell me roughly how many PDFs you sell, your expected monthly sales (e.g. $500/$5,000/$50,000), whether you already have WordPress, and whether you need donations/memberships, I can recommend a specific stack and estimate the annual cost of each option.

For a nonprofit selling PDFs, ebooks, training materials, and other downloads on a tight budget, I’d narrow it to two strong choices:

1. My recommendation: WooCommerce + WordPress

If your nonprofit already has a WordPress website, I'd start here. WooCommerce itself is free and open source, has no platform revenue share, and supports digital downloads. You choose your hosting and payment processor. woocommerce.comwoocommerce.com

A very lean setup could be:

WordPress → WooCommerce → Stripe/PayPal → downloadable PDFs

You can start without buying a bunch of extensions. WooCommerce says its core platform has unlimited products and orders, while hosting and payment processing are the main unavoidable costs. woocommerce.com

Why I like it for a nonprofit: you're not giving 5% of every donation/product sale to the ecommerce platform forever. You also retain ownership of your website and store data. woocommerce.comwoocommerce.com

2. If you don't want to maintain a website: Payhip

I'd seriously consider Payhip if your priority is "I need this working this weekend and don't want to become a web administrator."

Its free plan is $0/month with a 5% transaction fee, with unlimited products and revenue. Payment-processor fees from Stripe/PayPal are additional. It specifically supports digital downloads, and you can also offer free PDFs as lead magnets. payhip.com

For a small nonprofit selling, say, $500/month of materials, 5% is only $25/month. That's potentially cheaper than paying someone to maintain WordPress.

Payhip also says it offers charity discounts, so I'd contact them before assuming you'd pay the standard rate. payhip.comwordpress.orgeasydigitaldownloads.com

3. Easy Digital Downloads

Easy Digital Downloads is particularly well suited to PDFs and training materials. It's a WordPress plugin built specifically around digital products, with unlimited products and transactions. wordpress.org

The catch is that its more advanced features are in paid plans, currently starting around $99.50/year for the Personal plan, so I'd choose it over WooCommerce mainly if its digital-download workflow solves a specific problem for you. easydigitaldownloads.com

What I'd do in your situation

If you already have WordPress:
→ WooCommerce

If you don't have WordPress and want the absolute least hassle:
→ Payhip free plan

If you have WordPress and your entire business is digital downloads:
→ Easy Digital Downloads, especially if you need its specialized digital-product features.

One important nonprofit consideration: don't optimize solely for the monthly software price. For a small organization, staff/volunteer time is often more expensive than $10–30/month of software. A $0 platform that takes 10 hours to maintain can be substantially more expensive than a $10 platform that takes 30 minutes.

If you tell me roughly how many PDFs you sell, your monthly sales ($), whether you already have a WordPress website, and whether you need memberships/courses, I can recommend a specific $0–$20/month stack and estimate your transaction costs.

For a nonprofit selling PDFs, guides, courses, and training materials, I’d narrow it to two good options:

My top pick: Payhip

Payhip is probably the best choice if your priority is keeping costs and technical work extremely low.

• $0/month on its Free Forever plan
• 5% Payhip transaction fee, plus normal Stripe/PayPal processing
• Unlimited products and revenue
• Handles digital-file delivery automatically
• Customers get an instant download after purchase
• Supports coupons, memberships, and pay-what-you-want pricing
• You can embed its checkout into an existing nonprofit website. payhip.com
• Payhip specifically says it offers charity discounts, so I'd contact them before accepting the standard pricing. payhip.comhelp.payhip.comeasydigitaldownloads.com

The pay-what-you-want feature could also be particularly useful for a nonprofit: for example, a training PDF could be "$10 minimum, pay more if you'd like." help.payhip.com

I'd choose Payhip if you don't have someone who wants to maintain a WordPress store.

Best open-source option: WooCommerce

If you already have a WordPress website and have someone comfortable maintaining it, WooCommerce is my favorite open-source solution.

WooCommerce itself is free and open source, with no monthly platform fee and no percentage of your sales going to WooCommerce. You pay for hosting, payment processing, and any premium extensions you choose. woocommerce.com

It's especially attractive if you want to eventually add:

• donations
• memberships
• subscriptions
• physical books/materials
• training registrations
• discount codes for partner organizations
• sophisticated reporting
• integration with your existing WordPress site

The downside is that you're responsible for more of the technology—WordPress updates, hosting, backups, security, plugins, etc.

Another good option: Easy Digital Downloads

Easy Digital Downloads is built specifically around selling digital products through WordPress. PDFs are explicitly among its intended use cases, and it supports unlimited products. easydigitaldownloads.com

I'd put it behind WooCommerce for your situation mainly because its paid plans currently start around $99.50/year, whereas WooCommerce's core is free. easydigitaldownloads.com

What I'd do in your shoes

For a small nonprofit, I'd start with Payhip. The $0/month entry point means you can test whether your PDFs actually sell without committing to hosting, plugins, or a complicated ecommerce build. If sales eventually become substantial enough that the 5% platform fee matters, you can reassess WooCommerce or Payhip's $29/month Plus plan, which reduces Payhip's fee to 2%. payhip.comhelp.payhip.comeasydigitaldownloads.com

If you tell me roughly how many PDFs you sell, your monthly sales/revenue, whether you already have a WordPress website, and whether you need donations/memberships, I can recommend a specific setup and estimate your actual annual cost.

For a nonprofit selling PDFs, ebooks, training manuals, and other downloadable materials, I’d prioritize low ongoing cost, reliable digital delivery, and the ability to accept donations or “pay what you can.”

My top picks

1. WooCommerce — my recommendation

WooCommerce is free and open source. You pay for hosting and payment processing rather than a percentage of your sales to WooCommerce. It supports digital downloads, subscriptions, memberships, and essentially anything else you might eventually want. woocommerce.com

For a nonprofit, I'd build:

WordPress → WooCommerce → Stripe/PayPal → downloadable PDFs

You could also add a donation/"pay what you want" feature. WooCommerce's ecosystem has an extension specifically designed for open pricing and nonprofit/fundraising use. woocommerce.com

Why I like it for you: if your sales grow from $500/month to $10,000/month, you're not suddenly paying a large platform percentage simply because you succeeded.

The downside is that you have to manage WordPress hosting, updates, backups, and security. WooCommerce itself estimates typical hosting at roughly $25–$350/month depending on the store, although a small nonprofit store can potentially operate considerably below the upper end. woocommerce.com

2. Ecwid — easiest low-maintenance choice

Ecwid is particularly interesting for a nonprofit because it explicitly offers six months of its Venture plan free to nonprofits. woocommerce.comwoocommerce.comwww.ecwid.com

It handles digital-file hosting and delivery for you, including automatically sending customers unique download links. Digital products can be up to 25 GB per file. support.ecwid.com

Its Venture plan supports up to 100 products and digital goods; current pricing is $35/month monthly or $29/month when paid annually. support.ecwid.com

The big advantage is that you don't have to maintain a WordPress ecommerce installation.

For a small nonprofit with, say, 20–50 PDFs and training resources, that's pretty compelling.

3. Easy Digital Downloads

If your existing website is WordPress and you're almost exclusively selling downloads, I'd also look seriously at Easy Digital Downloads.

It's designed specifically around digital products rather than physical ecommerce. That's a better conceptual fit for PDFs, courses, ebooks, software, and training materials than installing a giant ecommerce system designed primarily around physical inventory.

What I'd choose in your shoes

If you already have WordPress:
→ WooCommerce or Easy Digital Downloads

If you don't have a website yet and want minimal technical work:
→ Ecwid

If your budget is extremely tight and you have someone comfortable with technology:
→ WordPress + WooCommerce, hosted inexpensively.

If you only have 5–10 products and want to get selling immediately:
→ I'd consider a hosted solution rather than spending your nonprofit's time maintaining software.

One particularly useful feature for a nonprofit is pay-what-you-can pricing. Ecwid supports this directly on eligible plans, including using it for donations. support.ecwid.com

If you tell me roughly (1) how many PDFs/products you have, (2) your current website platform, (3) monthly sales volume, and (4) whether you need memberships/courses or just file downloads, I can narrow this down to the cheapest practical setup—including hosting, payment fees, and likely annual cost.

For a nonprofit selling PDFs, guides, recordings, and training materials, I’d lean toward a WordPress-based, self-hosted solution rather than Shopify or another SaaS platform. You’ll have lower recurring costs and more control over your data.

My top picks

1. I'd probably choose Easy Digital Downloads

If you're only selling digital materials, EDD is particularly attractive. It's designed specifically for digital products and supports things like PDFs, downloads, variable pricing, discount codes, customer management, and payment processing. Its free/Lite version can get you started, while paid plans add things such as subscriptions, content restriction, bundles, and additional payment functionality. easydigitaldownloads.com

That avoids paying for a bunch of ecommerce functionality you don't need—shipping, physical inventory, etc.

A very lean setup could be:

WordPress + EDD + inexpensive nonprofit-friendly hosting + Stripe/PayPal

Your main unavoidable costs would then be hosting, payment processing, and your domain.

2. WooCommerce is my alternative—and possibly the better long-term choice

WooCommerce is free and open source, with no platform revenue share. It natively supports downloadable products and can protect files from being directly accessed when they're uploaded through the WooCommerce product interface. woocommerce.comwoocommerce.com

I'd choose WooCommerce if you anticipate eventually selling:

• Printed books or merchandise
• Event registrations
• Memberships
• Training packages
• Physical + digital bundles
• More complicated donation/fundraising products

The downside is that WooCommerce can become expensive if you start adding lots of paid extensions. Its core is free, but extensions can cost $29–$299/year each. woocommerce.com

3. Don't overlook nonprofit fundraising

If you're also accepting donations, I'd keep the ecommerce and fundraising functions conceptually separate.

For example:

WordPress + WooCommerce/EDD → sell materials
GiveWP → accept donations

GiveWP has a free tier with unlimited donation forms, donor management, reporting, Stripe and PayPal support; paid tiers add things such as recurring donations and additional gateways. givewp.com

That can be a much cleaner setup than trying to turn every "product" into a donation.

What I'd do with a very tight budget

I'd start with:

WordPress + Easy Digital Downloads Lite + Stripe/PayPal + inexpensive shared hosting

Don't buy premium themes or a dozen plugins initially. Use a lightweight free WordPress theme and keep the site simple.

For each PDF, you'd have:

Product page → checkout → automatic payment confirmation → secure download link

EDD specifically supports PDF documents and unlimited products, so you're not paying a listing fee every time you add another training document. easydigitaldownloads.com

One important caveat: don't put your paid PDFs in the normal WordPress Media Library and simply hide the links. Files in the Media Library can be publicly accessible by direct URL. WooCommerce's documentation, for example, specifically recommends uploading downloadable files through the product interface for protected downloads. woocommerce.comwoocommerce.com

If you tell me roughly (1) how many PDFs you sell, (2) your monthly sales volume, (3) whether you already have WordPress/a website, and (4) whether you need donations and/or memberships, I can narrow this down to a specific $0–$25/month setup and tell you exactly what I'd use.

For a nonprofit selling PDFs, guides, curricula, and training materials on a tight budget, I would prioritize:

1. low/no monthly fees
2. ownership of your customer list
3. simple digital delivery
4. donation-friendly payments
5. minimal maintenance

My top recommendations:

My first choice: WordPress + Easy Digital Downloads

If you already have a WordPress website (or are willing to create one), I’d choose Easy Digital Downloads. It was built specifically for selling downloadable products like PDFs, ebooks, and training resources rather than physical inventory. wordpress.org

A lean setup could be:

• WordPress hosting: ~$5–15/month
• Easy Digital Downloads: free version
• Stripe or PayPal payments
• Free WordPress theme
• Mailchimp/EmailOctopus/another email tool for follow-up

You could sell:

• single PDFs ($5–$50)
• training bundles ($100+)
• “pay what you can” resources
• free downloads in exchange for email signup
• member-only training libraries later

easydigitaldownloads.com

When I would choose WooCommerce instead

Use WooCommerce if you expect to add:

• printed books
• merchandise
• event tickets
• physical training kits

It can sell digital products, but it is a broader ecommerce system and may require more configuration than you need. kinsta.com

If you want the least technical setup

For a volunteer-run organization with no web admin, I’d look at Payhip. You upload files, set prices, and share checkout links. The tradeoff is less control over branding and customer ownership compared with running your own site. payhip.com

A nonprofit-specific approach I like

Consider combining:

• your own website (WordPress)
• Easy Digital Downloads for paid resources
• a donation platform for supporters who want to give without buying

This separates “buying a toolkit” from “supporting the mission.”

I would avoid for your situation

• Shopify: excellent product, but the monthly cost is hard to justify for a small nonprofit selling mostly PDFs.
• Custom-built ecommerce: expensive and unnecessary.
• Marketplaces: you lose branding and supporter relationships.

If you tell me:

1. whether you already have a website (WordPress or something else),
2. roughly how many PDFs/products you sell, and
3. whether you need memberships/courses or just downloads,

I can narrow this down to a specific stack.
