Paymenter extensions by Karelia Labs
Karelia Labs builds extensions for Paymenter, the open-source billing panel for hosting companies. Each one does one job, uses the platform's own extension system and never edits core files.
The paid extensions are one-time purchases on Gumroad. Pay All Invoices, the Pelican extension and Sign in with Paymenter are free there.
Paid, on Gumroad: Karelia Bridge ($24.99) signs customers in to Pterodactyl 2.0 from Paymenter and shows due dates and unpaid invoices in the panel. The EU Withdrawal Button ($12.99) adds the EU withdrawal function, the German cancellation page and mandatory checkout checkboxes. Free Trials ($12.99) gives one trial server per person, and Auto Stock ($4.99) keeps product stock in line with the free room on your Pterodactyl nodes.
Free: Pay All Invoices lets clients pay every unpaid invoice with one payment, the Pelican Panel Server Extension sells servers on Pelican Panel, and Sign in with Paymenter lets customers sign in to Pterodactyl 2.0 with their Paymenter account. All three are free downloads on Gumroad. Pterodactyl 2.0 for Paymenter, the server extension that keeps server creation working after the Pterodactyl 2.0 upgrade, is free on GitHub and SourceXchange.

Fix Paymenter after upgrading to Pterodactyl 2.0: "api/application/nests could not be found"
Pterodactyl 2.0 removed the nest endpoints that Paymenter's built-in extension calls. Switch to a 2.0-aware extension with one command; products and services stay.
Read the guide →How to offer free trial game servers in Paymenter, one per person
Paymenter 1.5.9 has no trials of its own. Make a separate trial product with a free plan, allow one trial per person at checkout, end it with Paymenter's own suspend and terminate, and let clients upgrade on the same server.
Read the guide →How to keep Paymenter stock in line with free Pterodactyl node capacity
Paymenter's stock only changes when you change it. Count what still fits on each node by the panel's own rule (memory, disk, overallocation and free ports), or let Auto Stock set every product's stock from it on Paymenter's scheduler.
Read the guide →Paymenter with Pterodactyl 2.0: setup guide (nests error, SSO, stock, invoices)
The Pterodactyl 2.0 upgrade breaks server creation in Paymenter and leaves three things to set up on purpose: customer sign-in, stock that follows your real capacity and invoices in the panel. Tested on Paymenter 1.5.9.
