"Our ERP can't have an interface." Why that is a mistake.
The ERP is the heart of the business. That's true. But hearts pump blood, they don't hoard it. As long as your ERP doesn't share data, the rest of the company is manually working against it.
The master data team. The manual exports. The errors that happen anyway.
At some point someone decided: nobody touches our ERP. Too important. Too sensitive. Too much risk.
The result: a master data team that manually enters customer data every time a prospect becomes a customer. An inside sales team pulling exports, preparing them and forwarding them. A sales team switching between CRM and ERP because the systems do not talk to each other.
And duplicates still happen. Because people make mistakes, just like machines. Only without the ability to define logic that prevents those mistakes.
Three situations that arise when the ERP stays an island.
We see these situations in almost every company that comes to us.
Prospect becomes customer, nobody tells the ERP
Sales closes the deal in the CRM. Now someone has to manually create the new customer in the ERP. Verify address, assign debtor number, set payment terms. The master data team has more work. And until it is done no invoice can be issued.
The result: Delays in the invoicing process and manual effort that repeats every single day.
Quotes get created in the wrong system
The CRM has no current prices or product information because those live in the ERP and no interface exists. So quotes end up being written in the ERP. Sales juggles two systems, loses overview and time.
The result: The CRM becomes a contact manager instead of the central sales tool.
Revenue and KPIs are missing from the CRM
The sales manager wants to know how much a customer bought last year. That information lives in the ERP. It is not visible in the CRM. So they call accounting. Or export it themselves.
The result: Decisions based on data nobody can pull up at the press of a button.
The interface gets rejected before it has been designed.
The concern is understandable: if the CRM can change customer data, the wrong address might end up on an invoice. If external systems can write to the ERP, we lose control over master data.
That is true if the interface is poorly designed.
But an ERP interface does not have to mean every system can read and write everything. It is about clear rules: the ERP remains the leading system for customer master data. Addresses are changed there, not in the CRM. But the CRM can read. And certain data like new customer numbers can be transferred automatically.
The question is not whether an interface can be secure. The question is whether it gets designed well.
First understand what should flow where. Then build.
Before we build an ERP interface we clarify which data should flow in which direction and who owns it.
Customer master data is owned by the ERP. Full stop. Sales contacts are managed in the CRM, because ERP contacts are often different people and an unnecessary contact sync creates more problems than it solves. Product prices and information flow from ERP into CRM so sales can create quotes directly in the CRM. Revenue and KPIs flow from ERP into CRM so sales has the full customer context without switching systems.
The result is a sales team that works primarily in the CRM, without detours into the ERP. New customers land automatically in the ERP when the deal is won. No master data team creating records on demand. No sales rep maintaining two systems at the same time.
Master data team relieved. Sales works only in the CRM.
A B2B company with 12 sales reps. CRM and ERP have existed side by side for years, without a connection. A two-person master data team manually creates new customers in the ERP whenever sales closes a deal. Average wait time until first invoice: 2 days.
We analyse which data flows are actually needed and which are not. No full synchronisation, just targeted handoffs at the right points.
- New customer creation in ERP fully automated on deal close in CRM
- Product prices from ERP synced to CRM, quotes now created directly in CRM
- Revenue and open items from ERP visible in CRM
- Master data team relieved of manual entry work
- Time to first invoice: from 2 days to 0
“We said for years the interface was too risky. The whole time, the risk was the manual process.”
