## Description

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

The full edition — **Gatemi Sequential Order Numbers for WooCommerce**, sold on 
gatemi.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.

## FAQ

### Does this renumber my existing orders?

Never. Only orders placed while the plugin is active receive sequence numbers; everything
before keeps its original number.

### Does this plugin send any data anywhere?
