Running retail on one source of truth

Every multi-branch launch we've done starts with the same question: is there one record for this, or are there four?

When a retailer comes to us with two outlets and spreadsheets, the fix is obvious. When they come to us with eight outlets, six tools and a month of disagreement about last quarter's numbers, the fix is the same — it just takes more patience.

Where drift starts

Every outlet that has its own spreadsheet has its own version of the truth. Headquarters sees a reconciled view; the floor lives inside something else. Drift isn't a bug, it's the natural state of a multi-tool setup.

What one record gets you

When a sale at one outlet updates the same inventory record the warehouse reads, reconciliation stops being a task. Customer returns hit loyalty and ledger at once. A price change in shared data rolls across every outlet the next time a till opens.

None of that is magic. It's a choice we make on day one — stock lives in one place only — and defend across every feature request after.

How we phase it in

For a multi-branch launch we pilot at one outlet for a short window, with the manager on-site, then ripple out in small waves. By the time the last outlet is live, we've caught the edge cases that would otherwise show up on the first busy weekend.
