An ERP requirements document does not need to become eighty pages of theory. Leaders need a practical basis for comparison: what the system must solve, where the risks are and how success will be measured.

1. Business objective

Start with the business result ERP should improve: faster order cycles, more accurate inventory, less manual work, better reporting or clearer accountability between teams.

2. Process scope

Define which processes are in scope: sales, purchasing, warehouse, finance, production, documents, customer management. Each process needs a start, an end, an owner and the most common exceptions.

3. Data and source of truth

Name where customers, items, prices, stock, contracts, documents and statuses live. Without one source of truth, an ERP project quickly turns into a data dispute project.

4. Integrations

Separate what ERP must receive and what it must send to e-commerce, WMS, CRM, SharePoint, BI, banks, transport or other systems. Integrations need ownership, data format and error handling logic.

5. Roles and permissions

Requirements should show who creates, approves, edits, sees and exports data. This matters when the company grows and one person can no longer be the gatekeeper for every decision.

6. Reports and metrics

Do not write only that reports are needed. Define the decisions they support: purchasing planning, sales control, margin, inventory, project status or management dashboards.

7. Testing scenarios

The vendor should demonstrate real scenarios: request, order, stock, invoice, return, change, error and report. That reveals much faster whether the solution fits daily work.

Practical principle: If requirements do not include a process owner, data owner and testing scenario, the project is not yet ready for serious vendor comparison.

FAQ

Common questions about ERP requirements

Does the document have to be very detailed?

No. At the first stage, structure and decision logic matter more. Too much detail without process clarity often hides uncertainty.

Can this template be sent to vendors?

Yes, if it includes processes, data, integrations, roles and testing scenarios. Vendors can then respond in a comparable way instead of following only their demo path.

When should an external consultant be involved?

When the requirements touch several teams, involve integrations, have unclear data ownership or vendor proposals are difficult to compare.
