The situation
An industrial wholesaler closed deals in its CRM, and every closed deal then had to become an order and an invoice in its ERP. For years, someone in finance read the deal off one screen and typed it into the ERP as an order, then typed it again later as an invoice. Each keystroke was a chance to fumble a quantity, a price or a discount, and each retype opened a gap between what sales had agreed and what finance ended up billing.
The drift ran both ways. Sales did not see that finance had adjusted a price to fit a customer’s credit limit. Finance did not see that a deal had been revised after the order was already in the ERP. Each side trusted its own screen, both screens were stale in different ways, and the disagreement usually surfaced as an awkward call with the customer caught in the middle.
What we built
The fix was to close the loop rather than keep patching the re-keying. The deal would be entered once, flow forward through each stage automatically, and status would flow back so both sides read the same state.
When a deal was marked won in the CRM, its lines, quantities, prices and terms flowed straight to the ERP as an order, so the order could never disagree with the deal it came from. As that order was fulfilled, it flowed on to an invoice on the same basis, with the billed amount descending from the agreed amount along a path anyone could trace rather than through a second act of typing.
Diagram: a closed deal in the CRM flows to a sales order in the ERP, which drives fulfilment and invoicing. A sync contract carries the status and invoice state back to the CRM, so the loop closes. Nobody re-types the deal, and sales sees the same state finance sees.
The part that made it a loop rather than a one-way handoff was the return signal: fulfilment, dispatch, invoicing and payment states flowed back to the CRM against the original deal, so sales saw what finance saw on the same record, without having to ask.
Before any of that could run, sales and finance had to agree who owned what: who owned the price, who could change a quantity after the order existed, how a revised deal reconciled with an order already in flight. Those were operating agreements, not technical questions, and the flow only held once the two teams had settled them.
The outcome
The invoice matched the order, and the order matched the deal, so the reconciliation-by-email between sales and finance stopped being a weekly habit. A closed deal turned into cash on a path either team could follow on its own, and finance no longer needed to shadow every deal sales closed to catch what had changed along the way.
