MAXIMUM · Case study
One admin for ERP, stores and marketplaces.
Business Central, the stores, Amazon and Wayfair all lived in separate tools. We built one platform that runs them together.

SentryThe challenge
Many tools. One admin.
Each system did one job. None of them shared data, so every change meant work in many places.
From the MAXIMUM project record.
How data moves
Data comes in once. Every channel gets it.
Products and stock flow from Business Central and the feeds, through the admin, out to the stores, Amazon and Wayfair.

ERP deep dive
Where the data stays in sync.
Business Central stays the record. The admin maps, syncs and retries, so every channel shows the same state.
Built with
- Amazon
- Wayfair
- Dynamics 365
| Record | Owner | Flows to |
|---|---|---|
| Stock levels | Business Central | Admin, then stores, Amazon, Wayfair |
| Products and pricing | Business Central | Admin, then master and active feeds |
| Orders and returns | MAXIMUM Admin | Business Central |
| Customers and companies | MAXIMUM Admin | Business Central and stores, both ways |
Each record has one owner, so a conflict always resolves the same way and nothing is keyed in twice.

A failed sync is retried, not dropped
A dropped sync cannot quietly leave a store overselling. It is caught on the next cycle and sent again.
