Platform overview

What is the Invoice And Tax platform?

Invoice And Tax is an Arabic and English platform that issues e-invoices in Oman's PINT-OM UBL 2.1 format after deterministic, versioned validation, links every credit and debit note to its original, records supplier documents and payment allocations, prepares VAT return figures with maker/checker approval, and keeps an append-only audit trail of every action.

End to end

The life of a document

Every source — API, connector, spreadsheet or manual entry — follows the same path through the same rules.

  1. 01

    Capture

    Documents arrive from your ERP, accounting system, Excel or CSV files, or are entered by hand into one shared composer.

  2. 02

    Validate

    Versioned business rules and Schematron conformance checks explain any error before the document leaves.

  3. 03

    Issue

    The document is issued in PINT-OM and the issued version is frozen as a snapshot.

  4. 04

    Adjust

    Credit and debit notes carry controlled reason codes and stay linked to the original document.

  5. 05

    Settle

    Payments are allocated to invoices in an append-only ledger; corrections are reversing entries.

  6. 06

    Review VAT

    Return boxes are calculated from the tax ledger, checked for completeness and approved by a second person.

What the platform covers

Integration

Connects to what you already run

Most organisations already have an ERP, a point-of-sale system or an accounting package. Invoice And Tax connects to them rather than replacing them: through a versioned REST API, a connector framework with file and SFTP transports, or Excel and CSV import. Read more about integration options and the API.

Local by design

Designed for Oman, in both languages

The product interface works fully in Arabic and English with right-to-left layouts. It runs on Oman time, follows the gazetted e-invoicing timeline, and generates documents to the PINT-OM specification published for Oman.

  • Arabic and English interface
  • Oman time (Asia/Muscat)
  • Multi-organisation and multi-branch
Illustration: the same invoice shown side by side in English and Arabic, with matching fields linked between the two versions and a language switch above them.
