If you build WordPress plugins, the hard part usually is not the code. It is everything around the sale.
Someone buys. They need the ZIP and a license key. Your plugin has to check that key and respect site limits. When you ship a new version, they should update from their WordPress dashboard instead of digging through old email. If you charge yearly for updates or support, billing should renew without you chasing invoices.
A lot of people end up with a heavy ecommerce suite, a licensing add-on, and a separate update service. That works, but it is a lot of moving parts for one loop: take payment, issue a key, let the plugin validate it, and deliver updates.
Below is how that looks with Avenia Digital Products, plus a few decisions that matter on any stack.
Decide what you are selling before you build the product page
Before you upload a ZIP, get clear on the offer.
Is this a one-time purchase with a lifetime key? Or a year of updates and support that renews? Personal license for one site, or an agency license for several? Those choices drive pricing, activation limits, and whether you need subscriptions on day one.
A useful rule: price by what the buyer can do, not by a vague “Pro” label. If Agency means five sites and Personal means one, say that in the product copy and enforce it with activation limits. People understand site counts. They get confused by tier names that do not map to anything concrete.
You can start simple. Plenty of authors launch with a one-time purchase and a single-site license, then add multi-site tiers or renewals once real buyers show up.
Your store, your checkout
Install Avenia Digital Products on the site where you want to sell. Connect Stripe and/or PayPal on your own accounts, run a test purchase, then go live when it feels right. Checkout stays on your domain. Processors charge their normal fees; there is no marketplace cut on the sale.
Put the plugin on sale
Create a product for the plugin. If Personal and Agency are different activation counts, set those limits on the product (or use separate products / price tiers) so checkout matches what you promised.
Upload the ZIP, set the price, turn on license keys, and enable WordPress updates if licensed sites should get new versions from their dashboard. You can sell more than one plugin from the same store; each product keeps its own files, pricing, and license settings.
At checkout, the customer pays with Stripe or PayPal. When the order completes, they get a key, a secure download (not a public uploads URL), and a My Account login. That alone cuts a lot of “can you resend my download?” email. Put the key and download somewhere obvious in the purchase email too. If people have to hunt, they open a ticket.
Licensing from inside the plugin
The store handles commerce. Your plugin still has to enforce the license.
Point the plugin you sell at your store’s using the licensing integration guide. Customers enter their key in your settings screen; your plugin activates and validates it against the store so activation limits stick.
Updates without emailing ZIPs
With WordPress updates enabled on the product, licensed customers install new versions from Dashboard → Updates, same as any other plugin. You upload the new package on your store; eligible licenses pick it up from there.
That also makes yearly renewals easier to explain. People already understand “I pay so I keep getting updates.”
Full setup: WordPress plugin and theme updates guide. The guide covers themes too; this post is only about plugins.
Recurring billing when the offer needs it
If the purchase is truly one-time, skip subscriptions until you need them.
When updates or support are time-limited, offer monthly or yearly billing instead. Trials and setup fees are available if they fit. Customers cancel from My Account, so you are not tracking renewals in a spreadsheet.
Be clear on the product page about what stops when the subscription ends (updates, support, or access entirely). Ambiguous renewal copy is a common source of chargebacks and angry email.
Before the first real order
Buy your own product once in test mode and walk the full path: checkout, download, activate in a clean WordPress install, then ship a tiny version bump and confirm the update appears. You will catch awkward copy, wrong activation limits, and broken update checks faster that way than by rereading docs.
Plans for Avenia Digital Products are Solo, Studio, and Agency. Same features; the difference is how many production sites you can run. Details are on pricing page.
