Connecting sales, stock and management.

An online shop that prepares the order, a counter that keeps track of stock and figures.

Screenshots from October 29, 2026. The Comptoir screens are from its demo mode: sample data, flagged as such in the interface. The shop screens are from the live site.

Context

GPS — "the service that reassures" — sells phones, earphones, headsets, chargers, accessories, watches, perfumes, glasses and shoes, and offers money transfer. An online shop and a physical shop, with pickup or delivery.

The challenge

An order is prepared on WhatsApp, stock moves in the shop and at the counter, and the team don't all have the same rights: keeping one truth between the storefront, the stock and the figures.

Our contribution

Design and development of the public site and of the Comptoir GPS management tool, launch.

The decisions that held the project together.

  1. 01

    No online payment, and the site says so

    The customer builds their order, GPS confirms it on WhatsApp. Opening WhatsApp is neither sending, confirmation nor reservation: the site explains this.

  2. 02

    Stock rules written and tested

    The cart and WhatsApp reserve nothing; confirmation reserves; handover removes the stock; cancellation releases it. The database refuses to reserve more than the physical stock.

  3. 03

    Three levels of rights

    Owner (all rights), manager (no costs or settings), seller (sales, orders, customers) — checked on the server side.

  4. 04

    A Comptoir organised like a working day

    Steer, operate, develop; a keyboard command palette (Ctrl/⌘ + K) to jump to a product, an order or a customer.

  5. 05

    A history that doesn't rewrite itself

    Names, options and prices are frozen in each order line: changing the catalogue changes nothing in the past.
