A medical-device group operating several legal entities
Connecting the working system to the financial system
A group that chose Priority for finance did not have to move its people off the system they actually worked in — a bidirectional synchronisation layer turned double entry into single entry.

The challenge
Procurement and budgets were managed in a spreadsheet-based working system. The group decided to implement an ERP for finance, but to keep working where decisions are actually made. In practice that meant recording everything twice — once where the decision is made, and once where the accounting record lives.
Why a standard implementation was not enough
Double entry is not merely wasted time. It creates two versions of the truth that drift apart slowly: an order approved in one place and never recorded in the other, an invoice approved but not updated. The standard answer — move everyone into the ERP and close the working system — is correct on paper and fails in practice, because the approval processes the organization built are the processes people actually use.
Architectural approach
The architectural decision went the other way: leave the human workflow where it already happens, make the ERP the financial source of truth, and connect them. Each service was defined in the same structure — trigger, input, action, output — and written for every entity in the group rather than for a single company.
What was delivered
- Bidirectional interface services between the working system and the ERP
- Vendor creation after quality approval, checking for an existing record before creating one
- Budget transfers between lines as a controlled operation
- Purchase-order creation, returning the order number to the working system
- An invoice approval round spanning both systems
- Guarded cancellation: the operation is refused and returns an error when the order is already closed or carries an invoice
