Sequential Order Numbers for WooCommerce – Gatemi

WooCommerce numbers orders by database ID: 1503, then 1507, then 1512. Accountants, tax offices and invoicing rules expect a sequence. Gatemi Sequential Order Numbers gives every new order the next number in a gap-free sequence — atomically, so two orders placed in the same instant can never draw the same number.

A number is assigned once and never changes. It is frozen onto the order the moment the order is created. Orders placed before this plugin keep the numbers they always had, and disabling the plugin never renumbers anything.

Features

• Gap-free sequential numbers for every new order — checkout, admin-created, REST and Store API alike

• Atomic assignment: the counter advances in a single database statement; no race can mint a duplicate

• Start the sequence where your books start

• Pre-plugin orders are never renumbered

• A live “next order will be numbered” readout on the settings screen

• No tracking, no external requests, ever — this plugin never phones home

The full edition

com — adds a prefix and suffix with {YYYY} {YY} {MM} {DD} date variables and zero-padding to a fixed width. Your sequence carries over: the full edition continues counting exactly where this one stops.
