A custom internal system for an Amazon seller
A server-side platform unifying stock, orders, suppliers, and resource planning — one source of truth for the operations team.
- Client
- Amazon seller with an in-house ops team
- Scope
- Internal platform: stock, orders, suppliers, planning
- Replaced
- Seven scattered spreadsheets
The problem
The operations team ran the business on seven spreadsheets: stock in one, orders in another, suppliers in a third. Numbers disagreed, formulas broke silently, and every question started with “whose file is current?”.
Onboarding a new employee meant weeks of tribal knowledge about which cells not to touch.
What we built
- A server-side platform with one database for stock, orders, suppliers, and resource planning.
- Automatic sync with Amazon: orders, inventory, and settlement data flow in on schedule.
- Role-based screens for purchasing, warehouse, and management — each sees their slice.
- Audit trail: every change is logged, nothing breaks silently.
- Exports and reports the team previously assembled by hand.
How it works day to day
The spreadsheets are gone. Purchasing plans against live stock and inbound data; the warehouse works from the same numbers; management sees the state of the business without asking anyone to “update the file”.
Outcome
One source of truth for the whole operations team. Disputes about whose numbers are right ended — the platform’s numbers are the numbers.
The system is bespoke: it matches how this seller actually operates, not how a generic tool assumes they should.
