Licensing & Pre-Sale Questions
- Do I need a license for each website?
Yes. Each license works on one website only. If you run multiple stores, you’ll need separate licenses for each domain. Your license key won’t activate on different domains. - What happens if my license expires?
Your plugin keeps working, but you lose access to updates and support. Keys you’ve already created stay active. Renew anytime to get updates and priority support back. - Can I move my license to a new domain?
Yes. Deactivate the license from your old site first, then activate it on the new domain. You can do this from your PluginEver account or contact support for help. - Will this work with my existing WooCommerce setup?
The plugin works with WooCommerce 7+ and WordPress 6+. It plays nice with most themes and payment gateways like Stripe, PayPal, and Square. Check the compatibility list if you’re using specialized plugins. - What’s the difference between Free and Pro versions?
Basic handles simple key generation and email delivery. Pro adds SMS delivery, variable product support, bulk import/export, backorder management, and advanced generator rules. - Can I try it before buying?
Yes. We have a demo you can test from here. WC Serial Numbers Demo

Start here if you’re new. Follow the Installation and Activation guide to get the plugin running, then work through Selling Your First Serial Key to see how everything works end-to-end in just a few minutes.
Ready to set up your products properly? Configure a Simple Product walks you through the full setup for a single product. Selling in multiple editions or tiers? Configure a Variable Product covers key delivery per variation for Pro users.
Want to manage your keys hands-on? Add Keys Manually is the starting point for the free version. Once your keys are ready, Deliver Keys from Manual Key Pool.
When you are ready to automate, Set Up a Key Generator lets you define a custom key format, and Generate Bulk Keys creates a large batch from that generator in one click.
Once your generator is ready, follow Deliver Keys with Generator Rule to automate the key delivery. Prefer a fully hands-off approach? Follow Deliver Keys Using Auto-Generation to deliver a unique key for every order automatically, no generator setup needed.
Want more control over your store? Auto-Complete Orders After Payment skips the manual order completion step. Set up Low Stock Alerts to notify you before your key pool runs out. Reuse Keys recovers keys from failed or refunded orders, and Revoke Keys invalidates them automatically on cancellation or refund.
Need more flexibility? Manual Key Delivery guide lets you assign keys to orders by hand, Allowing Backorders keeps your store open even when the key pool is empty, and Allow Duplicate Keys lets you add the same key more than once. You can also Disable Key Delivery via Email, choose which key properties to Display in Order Details, and Translate Key Property Labels to match your store’s language and tone.
Got tons of keys to manage? Use Import Keys in Bulk to upload thousands from a CSV or TXT file. Need to pull data out? Export Keys gets your keys into a spreadsheet for reports or external use.
Building software that needs key validation? The REST API Guide works with modern apps and services. Running an older WooCommerce setup? Legacy API Setup keeps your existing integrations working.

Use Cases
Game Keys & Account Sellers
Sell Steam keys, Origin codes, or gaming accounts with complete automation. Import bulk keys from suppliers via CSV, then let customers receive them instantly after payment. Use SMS delivery to cut down on “where’s my key?” support tickets and keep gamers happy.
Digital Download Shops
Sell WordPress themes, plugins, or digital assets with instant key delivery. Start with basic email delivery, then upgrade to SMS for faster customer satisfaction and fewer support tickets.
Event Organizers
Generate unique entry codes for conferences, workshops, or concerts. Basic email works for small events, but SMS delivery (Pro) ensures attendees get codes instantly, even in poor email reception areas.
Software & App Developers
Distribute activation codes for desktop apps, mobile software, or SaaS platforms. Begin with manual key entry, then scale with generator rules (Pro) to handle hundreds of daily sales automatically.
Digital Agency Client Work
Manage licenses across multiple client projects. Start small with manual assignment, then leverage bulk import/export (Pro) to handle enterprise clients with thousands of keys.
E-Learning & Course Creators
Sell access codes for online courses, tutorials, or coaching programs. Email delivery gets you started, while variable products (Pro) let you sell different course tiers with unique access levels.
Physical Product Authentication
Add serial numbers for warranty claims, product registration, or anti-counterfeiting. Basic tracking works initially, but Pro’s advanced reporting helps scale as your product line grows.
