ERP Integration Checklist
A practical starting point for planning how rental, leasing, workshop and warehouse operations should connect to your ERP and other enterprise systems.
Most fleet and mobility businesses run operations in one system and finance in another, with someone re-keying data between the two. Integration removes that step — but only if it's planned properly. This checklist covers the areas worth thinking through before any integration work starts.
1. Map your current process first
Before connecting any systems, document how a transaction actually flows today — from booking or agreement, through to invoice, through to the entry your finance team makes in the ERP. Most integration problems trace back to gaps in this mapping, not the technical connection itself.
2. Get your master data in order
- Chart of accounts — which operational transactions map to which GL codes?
- Customer master — one source of truth, not separate customer lists per system.
- Vehicle/asset master — consistent vehicle IDs across operations and finance.
- Branch and cost center mapping — how do operational branches map to ERP entities?
3. Decide what actually needs to integrate
Not everything needs a real-time connection. Typical candidates: invoice and billing postings, customer payments and receipts, vehicle/asset data, and GPS or telematics feeds for utilization reporting. Batch/scheduled sync is often good enough for reporting-only data; real-time matters most for billing and payments.
4. Plan approvals and controls
Decide what needs human approval before it posts to finance (e.g. credit notes, discounts, high-value adjustments) versus what can flow through automatically. Building this in from the start avoids a painful retrofit later.
5. Test with real transaction volume
Run a full month-end cycle in a test environment before go-live, not just a handful of sample transactions. Reconciliation issues usually only show up at volume.
Common pitfalls
- Starting integration work before master data is clean.
- No agreed owner on either side (operations vs. finance) when something breaks.
- Treating go-live as the finish line instead of month one of monitoring.
