Invoice data readiness checklist for e-invoicing

Clean invoice data makes every future step easier: approvals, customer sharing, reporting, structured exports and integration with approved providers when required.

Customer and supplier records

Start with master data. If customer or supplier details are incomplete, invoice preparation and follow-up become slower. Duplicate records also create reporting confusion.

  • Legal name and display name
  • Billing address and country
  • Tax registration or business identifiers where applicable
  • Payment terms and contact details

Invoice fields

Invoices should be generated from structured fields rather than recreated manually each time. This gives the business cleaner reports and better readiness for future formats such as JSON, XML or API payloads.

  • Item or service lines
  • Quantity, unit, discount and currency
  • Tax fields and totals
  • Invoice number, date and status
  • Linked quotation, proforma invoice or delivery note

Approvals and evidence

A ready invoice workflow should show who created, reviewed, approved, sent or changed an invoice. This is useful for internal control even before formal e-invoicing rules apply.

  • Approval status and approver names
  • Comments or exception notes
  • Attached documents and PDF copies
  • Customer sharing and follow-up history
