Overflow Billing – FiveM Billing & Invoice App

Overflow Billing is not another pop-up menu. It registers as a native app in lb-phone and qs-smartphone, with its own icon, app store entry and push notifications, and the script detects on its own which phone your server is running. If you have no phone resource at all, it falls back to a standalone NUI opened with a command or a configurable keybind, so the same FiveM billing script works on every server without a second version to maintain.

Creating an invoice takes one screen: pick who is sending, search for the recipient, set the amount and write a short summary. Recipients can be any player on the server or any registered job, so a mechanic can bill a customer and a company can bill another company. Employees on duty switch between their personal identity and their society from the account picker, and every request is re-validated on the server before an invoice is written to the database.

Most FiveM invoice scripts only handle a single lump sum. Overflow Billing lets you break a total into up to ten scheduled payments on a daily, weekly, biweekly, monthly or quarterly cadence. The app divides the amount, tracks how many instalments have been settled and closes the invoice automatically on the final payment, which makes financed vehicle sales, property payments and long-term contracts work without a second script.

The home screen answers the two questions players actually have: what do I owe, and who owes me. Received and Sent are separate ledgers, each split into Pending and History, with a running total at the top and a badge for how many invoices are still open. Nothing is hidden in a chat command or a log file, and both the payer and the issuer get a phone notification the moment an invoice is sent, paid or cancelled.

Open the admin panel in game and pick a job: decide whether that society can send and receive invoices at all, then go grade by grade choosing who can issue invoices and who can manage them. Give a grade a commission percentage and the employee who raised the invoice takes their cut automatically when it is paid, with the remainder going into the company account. Everything is saved straight to the database, so adjusting a job's permissions never means touching a config file or restarting the server.
