Case study · E-commerce + SaaS
Maison HauteFrom a town-centre boutique to real sales software, online and at the counter.
Maison Haute is a decor, art objects and tableware boutique in Menton. It sold in its shop window and on a marketplace, Etsy. It wanted to take back control: its own online store, and one tool for both the website stock and the shop stock.

01The brief
Stock was kept by hand in a spreadsheet, and online sales went through a platform that was not its own. The store had to sell online in the house style, and every sale, online or at the counter, had to update the same stock, with no double entry.
02What we built
For visitors
- Catalogue by collection, search, detailed product pages, wishlist
- Multi-step checkout: account, delivery, payment
- Delivery at the carrier's real rate, calculated live
- Click & collect: pick-up slot chosen at checkout
- Secure payment and promo codes
- Customer account, reviews, journal and newsletter
- French and English
For the team
- Website and shop stock in a single table, per variant
- Three numbers per item: on the shelf, held by a payment in progress, available
- Counter sales entered from a phone, search by reference or barcode scanner
- Shop hours, pick-up slots and one-off closures editable
- Accounting by channel, online and in-store: net, VAT, numbered invoices, ledger
- Excel and CSV exports for the accountant
- Orders, customers, promo codes, reviews, homepage and statistics managed without a developer
The management area is private: we describe it, we don't show it.
