How to recognize the profile

Do not rely on the file extension alone. Inspect the root namespace, customization/profile identifiers, version values and authority-specific envelope.

  • Singapore PINT customization
  • UEN endpoint schemes
  • IRAS invoice-data fields

Production validation stack

  1. 1
    PINT Singapore rules

    Confirm that the document is well formed and structurally compatible with the intended InvoiceNow syntax.

  2. 2
    Peppol capability

    Apply semantic and business-rule checks rather than accepting a file merely because it parses.

  3. 3
    GST data submission requirements

    Validate currencies, countries, tax categories, units, payment means and other controlled values against the correct release.

  4. 4
    IRAS timing and transaction scope

    Apply the national, network or authority restrictions that narrow the base syntax.

EInvoiceLab’s browser tools provide detection, inspection and technical preflight. A profile is only production-valid after applying the correct official artefacts and obtaining the required network or authority outcome.
