Point of sale for WooCommerce shops: Retail point of sale

01Why it exists

Built for a retailer running an off-the-shelf point of sale plugin it could not fix when it disagreed with the web store about stock. It began as a terminal served from inside WordPress, writing ordinary WooCommerce orders against the high-performance order tables, and has since been rebuilt as a service of its own.

02How it works

The standalone version is a Node API over PostgreSQL with Redis, and a browser terminal designed for a counter rather than for an admin screen: large targets, keyboard-first, and no navigation the cashier has to think about. It covers products and categories, sales and line items, customers, cashiers, cashier sessions with open and close, inventory movements with a reason for each, and reports.

Synchronisation with the web store is explicit rather than implicit. Every push and pull is recorded with a direction and a status, so when the counter and the website disagree there is a log that says when they last agreed and what happened since.

When the two disagree, the log shows when they last agreed.

03At the counter

At the counter it works with the fiscal device that Cyprus law requires.
