Document Numbering Register Offline

When several people issue documents from separate files, numbers get repeated, skipped or quietly reused, and month end turns into a hunt for the missing ones. This register is the single place where a number is taken, so nobody guesses the next one and every gap has a reason written next to it.

Set up your series under Series and rules (prefix, digits, start, and whether a voided number may be reused). Whenever someone needs a number they take it on Take a number and say what it is for. A wrong or cancelled document is voided with a reason, and its number stays in the register. Checks lists missing numbers and old reservations, and the register exports to CSV.

What is inside:

• Take a number, Register, Checks, Series and rules and About tabs
• Several series, each with its own prefix, digits and rules
• Reserve a block of numbers, and record numbers used before you started the register
• Void with a required reason, optional reuse, and a history of every change to each number
• Missing numbers, old reservations and other checks, a by-person view, CSV export, JSON backup, example data

Who it is for: finance teams, shops with several counters, project teams and anyone who hands out document numbers to more than one person.

What it is not: It records numbers. It does not issue the documents themselves. It is a record on one device: if two people use two copies they can hand out the same number, so one person should run it or the export file should be passed around. Whether and how a business may reuse or skip invoice numbers is for your accountant and the tax authority to say. The app only enforces the rules you set.

How it differs: The quotation-and-invoice-maker-offline-uae numbers its own documents. This register is for numbers that come from anywhere, including a paper book, another system or a word processor.

Tested: 54 scripted browser checks: 500 numbers taken in a row were all unique and gap free, voiding needs a reason, a voided number is not handed out again and reuse is refused unless the series rule allows it, yearly series restart at 1 even with backdated entries, duplicate backfill is refused, planted gaps (100, 101 and 200) were found and shown as ranges, blocks can be reserved and released, stale reservations are flagged, and CSV, print and backup work. Typing in the series fields keeps focus while the tables update. It was tested in Chromium only. Firefox, Safari, a real phone and a real printer were not available for testing.
