UAE E-Invoicing and Peppol PINT Compliance

The problem this solves

The UAE e-invoicing mandate changes what an invoice is. A PDF emailed to a customer stops being the document of record. B2B invoices and credit notes must be issued as structured electronic documents in the Peppol PINT AE format and exchanged through an accredited service provider on the Peppol network, with the tax authority receiving its copy through that same channel.

For an SAP Business One site that means the finance team can no longer close a sale by pressing Add on an A/R Invoice. Somebody has to produce a structured document containing fields SAP does not capture today — the customer's Peppol participant identifier, a scheme-qualified tax registration number, the correct document type code, unit-of-measure codes from an international list, and tax categories that match the UAE VAT rules exactly. Then somebody has to transmit it, wait for a response, and prove months later what was sent and what came back. Done manually, this is a portal, a spreadsheet and a person. Done wrong, invoices are rejected, revenue recognition slips, and your customers cannot claim input tax on documents that never arrived.

The deeper risk is silent failure. An invoice that was never accepted still looks perfectly posted in SAP unless something inside SAP tracks its clearance status.

What ECOSIRE builds for you

ECOSIRE builds a per-tenant SAP Business One add-on that makes the compliance state of every document visible and enforceable inside SAP itself. This is built to order against your company database, your tax setup and your chosen accredited service provider — it is not a downloadable product.

Master data readiness

Compliance fails on master data long before it fails on transmission. The build adds validated UDFs to Business Partner master data for the Peppol participant identifier and its scheme, the tax registration number and its scheme, the legal entity name and registered address in the structure the format requires, and the buyer reference where your customers demand one on their documents. Item-level UDFs carry classification and unit-of-measure codes mapped to the international code lists. A pre-flight validation screen lists every Business Partner and item that would fail before you issue a single document, so remediation happens on your timetable rather than at month end.

Document mapping and generation

When an A/R Invoice, A/R Credit Memo or A/R Down Payment Invoice is added, the add-on reads it through the Service Layer (REST) — using the DI API where an object requires it — and generates the structured PINT AE document. Mapping covers document and tax point dates, the document type code, seller and buyer parties, line items with quantities and unit codes, allowances and charges, tax categories and rates derived from your SAP tax codes, exemption reason codes where a line is zero-rated or out of scope, rounding, and the payable amount. Currency and any required AED conversion follow the rates on the SAP document. Because the mapping is built for your configuration, your specific tax code set and revenue structure are handled explicitly rather than approximated.

Exchange through your accredited service provider

The add-on transmits to the accredited service provider you appoint, using the interface that provider publishes, and stores every request and response. Acknowledgements, business-level responses and rejections are written back onto the SAP document, so an invoice carries its own clearance status. Rejections surface with the returned reason code and message rather than a generic failure. Retry is controlled and idempotent, so a network timeout cannot cause the same invoice to be submitted twice under a new identifier.

Status, control and audit

A compliance cockpit built as a UDO shows every document by status — pending, submitted, accepted, rejected, cancelled — with drill-down to the SAP document and to the exact payload exchanged. Status fields on the document mean an accounts team can see clearance without leaving the invoice. Approval procedures can block posting when mandatory compliance data is missing, which is far cheaper than fixing a rejected document afterwards. Every payload, response, timestamp and identifier is retained in a UDT structured for the retention period, and Crystal Reports layouts provide submission logs, rejection analysis and a period reconciliation of posted revenue against accepted documents. Human-readable invoice layouts can be extended to carry the identifiers your customers expect to see.

Who this is for

Companies operating in the United Arab Emirates that run SAP Business One and issue B2B invoices in scope of the mandate — distributors, contractors, services firms, manufacturers and trading companies, including groups running several UAE entities on one installation. It suits sites on SAP Business One 10.0, SQL Server or SAP HANA, on-premise or cloud-hosted. It does not replace your accredited service provider; it connects SAP to the one you appoint.

How delivery works

1. Scoping call. We review your document types, VAT treatments including zero-rated, exempt, reverse-charge and export cases, your entity structure, your customer base, and which accredited service provider you have appointed or are evaluating.

2. Fixed quote. You receive a written scope covering the exact documents, tax scenarios and provider interface in scope, at a fixed price, before development begins.

3. Build. ECOSIRE develops the add-on against a copy of your company database, typically over two to four weeks depending on the number of tax scenarios and entities.

4. Install in test. We install into your test company database and run real document shapes through the provider's test environment, including deliberate failure cases, so you see rejection handling working before it matters.

5. Install in production. After sign-off we install into the production company database, complete provider onboarding steps that require the live environment, and supervise your first live submissions.

6. Support. A support window is included for defect fixes and for changes to the PINT AE specification or your provider's interface within the delivered scope.

ECOSIRE is a software development company. We build the SAP-side integration; accreditation, network participation and the legal filing relationship remain with your appointed service provider and your tax advisors.
