The cost hiding between your ERP and your spreadsheets.
Your ERP records what happened. Your spreadsheets decide what happens next. The money leaks in between.
Walk into almost any mid-market manufacturer and ask how the weekly plan is made. The answer is rarely 'in the ERP'. It's an export, a spreadsheet, a set of lookups maintained by one or two people, and a meeting.
The ERP is the system of record. The spreadsheet is the system of decision. And the space between them is where cost accumulates quietly.
What leaks through the gap
- Stale data. Decisions made on Monday's export while the situation changes on Tuesday.
- Partial joins. The spreadsheet has the POs but not the supplier's real delivery history; the forecast but not the capacity.
- Invisible logic. Rules that live in one planner's formulas and leave when they do.
- No feedback. Nobody measures whether the decision was right.
Most supply-chain cost isn't caused by bad decisions. It's caused by good people deciding with partial data.
Closing the gap without replacing the ERP
Replacing the ERP is a multi-year project. Closing the gap is not. It needs a layer that reads from the systems you already run, joins what the spreadsheet can't, and turns it into ranked, explained decisions.
That's the layer WERISCO is built to be.
One supply-chain shock, decoded in numbers, and what a data-driven plant does about it.
