An e-invoicing integration discussion is more useful when it starts with real source data rather than a list of software logos. Before deciding whether to connect an ERP or adopt a different invoicing workflow, bring a small, redacted evidence pack. The aim is to find what your current system can provide, where the gaps sit and who can resolve them.
1. Identify the source of each invoice
List the systems that create invoices, credit notes and any other document types your business uses. Record the software version, legal entity and business process behind each source. A trading business might create invoices from sales orders, while a services business might work from approved time or milestones. Those are different discovery questions even when both use the same ERP.
Choose one representative invoice and one correction. Remove personal information and commercially sensitive details before sharing them. Explain which fields are entered by a person, which come from master data and which are calculated by the system.
2. Map identities, lines and totals separately
Finance should identify seller and buyer records, tax registrations, currencies, invoice dates and document references. Then inspect a line: quantity, unit, price, discount, tax category and any additional charges. Finally, explain how the invoice totals reconcile. This is a discovery checklist, not a complete statutory field specification.
Keep an explicit list of uncertain fields. A blank buyer identifier and an identifier that the team has not yet verified are different issues. Do not fill either with invented placeholder values simply to make a sample payload pass.
3. Inspect interfaces before promising a connector
IT should bring the API or export documentation available for the actual installation. Confirm authentication, permissions, rate limits and whether the source supplies change events or requires polling. A connector claim needs more than the ERP's brand name: versions, localisations, custom modules and access rights can alter the integration.
For Odoo or another named ERP, agree an installation-specific compatibility review. Treat a connector as supported only after the intended scope has been accepted and tested.
4. Decide who owns the status and the exception
Draw the journey from source invoice to preparation, provider handoff and returned status. Ask where a finance user sees a rejection, who can correct the source record and how the corrected document is linked to the original. Test retries and duplicate protection as deliberately as the successful path.
A useful workshop ends with named responsibilities: finance owns the tax and commercial data; IT owns interfaces and technical recovery; the appointed provider owns the contracted exchange role. Confirm the precise boundaries rather than assuming the software vendor performs every role.
5. Agree evidence for a pilot
Record the country, entity count, monthly volumes, document types and desired implementation period. Define the sandbox, test cases, acceptance criteria and the person who signs off each result. Keep production authority submission separate from a demonstration or test.
InvoiceNext Connect starts with this discovery process. If your needs point towards a simpler invoicing workflow instead, compare the deployed InvoiceNext Business screens in a demonstration. Neither conversation requires an assumption that you must replace your existing ERP.
