Runs on: PHP 8.1+ with MySQL/MariaDB, or SQLite for a local trial. 2-minute web installer, no Composer. Tested on PHP 8.3. Or run it in Docker: the Dockerfile is in the zip.
Technical owners can install it with one line and their license key: curl -fsSL https://deliora.ownware.io/install.sh | sh -s -- invoicer-pro <your license key>
Nothing is obfuscated or encoded; what you read is what runs.
Which license do I need?
It comes down to how many installations you need. Running your own business on one site is the Single license. A second domain of your own, or sites you build or run for other people, is the Extended license.
- Install it on one domain or subdomain you own or operate
- Change the source however you like for that installation
- Run your own business on it commercially, client work included
- Re-download the current build any time from your buyer portal
- A second site, or an installation you hand to a client as theirs, needs the Extended license
- No reselling, redistributing or sublicensing the source
- Not for offering it to other people as a hosted service
- Everything the Single license grants
- Install it on as many domains as you own or operate — no cap on the number
- Up to ten client installations, one per client project, handed over or hosted for each client; for more, buy another Extended license
- White-label: remove or replace the product name and logo in the screens of client installations
- Still no reselling or redistributing the source itself
- Running it as a multi-tenant service others sign up for needs a SaaS agreement
Every download carries the full terms as LICENSE.txt. The complete wording is on the terms page.
After you buy
Your download link always serves the current build. Download again any time from your order page or the buyer portal; there is no renewal fee.
Email support for installation and for defects in the code as delivered: a person reads and answers every message. It does not cover custom development or server administration. What support covers
Refunds are handled by Lemon Squeezy as merchant of record, case by case. EU consumers keep the statutory 14-day right until delivery starts. Refund terms
It keeps running: your server, the full PHP source, no license check that can fail. If no stable release is published for 365 days, the domain limit lifts; after three such years your copy becomes MIT-licensed. The terms have the exact wording: continuity.
