Hire SaaS Developer for Retail Shops
Senior, direct, no layers

A SaaS developer builds multi-tenant software products for a retail shops business: one product, sold as a subscription, where many customer organisations each get their own secure space inside the same system. This is product development, not a one-off tool: the architecture, billing, and onboarding are part of the product from the start, because they decide whether it can grow.

The work starts from the customer and the subscription: who pays, what they get, and how they start without hand-holding. A shop supplier might turn its ordering know-how into a product that many shops subscribe to, but only if each shop's data stays separate and each shop can start without training, which is the product test. A product that needs a developer to onboard every customer is a service wearing a product's clothes, and the engagement designs onboarding so it does not.

This fits a retail shops business turning its expertise into a product others subscribe to. It does not fit a business that needs software for its own use only: a single-tenant internal tool is cheaper and simpler, and the engagement says so rather than building product machinery nobody needs. Book a free discovery call and we will test the fit before any scope is agreed.

The build starts with the tenant boundary at stock level, because one shop seeing another's supplier prices or sales ends the product. Stock, suppliers, orders and sales are modelled per tenant from the first table, and tests deliberately try to read across tenants, including through shared suppliers and chain accounts.

Launch is proven on a real trading week, not a demo shop. A small group of real shops runs live stock and sales on subscription through a busy week, from delivery and shelf counts to reorder and sale, and billing, stock imports and support are fixed from what those shops actually hit before the product opens wider. Code, billing setup and hosting stay in the business's own accounts.

For a shop owner, the change is a shelf that stops going empty unnoticed: stock levels, supplier orders and reorder points sit together, so the next order is obvious before a customer asks for something that is not there, and a seasonal range can be planned without rebuilding the catalogue. A new shop can sign up, add its locations and ranges, load its suppliers and take its first delivery without waiting on the platform owner, and each shop's supplier prices and sales stay inside its own tenant. Growth comes shop by shop, with billing and support handled from one admin view while each shop keeps control of its own stock and staff roles.
