ERP-CRM Integration RFP: 2026 Scope & Checklist

The verdict in three sentences

An ERP-CRM integration project fails at scoping, not at coding — fuzzy synced objects, undecided flow direction, forgotten error handling. Investing 4,000 to 12,000 EUR in an upfront scoping mission halves the overrun risk on a connector that will cost 20,000 to 70,000 EUR. Your scope document and vendor scoring grid are your only real negotiation levers.

What your scope document must freeze

An integration scope does not describe software, it describes data flows. For each business object you must settle four questions: which system is master, which way the data travels, how often, and what happens on error. Without these answers every vendor quote rests on different assumptions and becomes impossible to compare.

Error handling is the most underestimated line item. A serious connector includes a rejection queue, automatic retry, alerting above a threshold and a GDPR audit log recording who synced what. Demand these four elements in writing.

Vendor scoring grid across 8 criteria

Comparing three integrators on price alone is the surest way to pick the low bidder who delivers a non-reversible connector. A weighted grid across 8 criteria makes the choice objective and defensible in front of an investment committee.

A 2026 order of magnitude: a custom bidirectional connector runs 20,000 to 70,000 EUR in build, with a support retainer of 700 to 2,000 EUR/month depending on the number of flows and the sync SLA. A realistic timeline is 8 to 16 weeks from kick-off to monitored go-live.

Mini case study

Marc, CIO of a 240-employee industrial mid-cap in Nantes, is preparing an RFP to connect his ERP and sales CRM. Without scoping, his three quotes range from 28,000 to 61,000 EUR: incomparable. He invests 9,000 EUR in a three-week scoping mission that freezes 7 objects, flow direction and rejection handling. Result: the three integrators re-quote on the same basis, the gap narrows to 34,000-41,000 EUR, and Marc negotiates a 1,100 EUR/month retainer instead of 1,800. The scoping paid for itself in the first negotiation round.

FAQ

Do I really need a paid scoping mission before the RFP? Yes as soon as the project exceeds two bidirectional objects. For 4,000 to 12,000 EUR it produces a scope that makes quotes comparable and avoids a mid-project 15,000 EUR change order.

How much is a custom ERP-CRM connector in 2026? Budget 20,000 to 70,000 EUR of build depending on the number of flows and mapping complexity, plus a 700-2,000 EUR/month retainer for supervision, API evolutions and SLA upkeep.

How do I guarantee connector reversibility? Require in the contract the handover of source code, technical documentation and the full field mapping. An integrator who refuses locks in your information system: it's an eliminatory criterion in the scoring grid.

What timeline should I expect from signature to production? 8 to 16 weeks for a bidirectional connector: 2-3 weeks of detailed design, 4-8 of development, 2-3 of testing and a monitored go-live with an active audit log.

What must the GDPR audit log contain? The timestamp of each sync, the object and ID involved, the flow direction and the status (success/rejection). It is essential in an audit and to trace a personal-data incident.
