Tax authorities worldwide are mandating structured electronic invoicing. The models differ, but the pattern is the same: your ERP must produce compliant invoice data, exchange it through accredited channels, and record the regulatory outcome. Two of the most active regimes right now sit in the Gulf.
The UAE runs a Decentralised CTC and Exchange model. Invoices are exchanged between supplier and buyer through Accredited Service Providers (ASPs) over the Peppol network in the PINT AE format, while the Federal Tax Authority receives invoice data in near real time. E-invoicing commences 1 July 2026, with mandatory adoption phasing in from there.
KSA runs a Clearance and Reporting model under the Zakat, Tax and Customs Authority. Invoices are submitted for pre-clearance, stamped with a clearance ID, QR code and cryptographic stamp, and only cleared invoices may be delivered to the buyer. Buyers can verify invoices through the ZATCA portal or by scanning the QR code.
Accredited providers such as Edicom carry the regulatory load: format validation, Peppol exchange, clearance submission, legal archiving and a monitoring portal. What they need from you is reliable, well-formed invoice data, and what your finance team needs back is the regulatory status of every invoice inside the ERP they already use. That bridge is what FloSynq builds and runs.
On a schedule, AR invoice transactions are extracted from your ERP, for example Sage 300 via SQL views or the Web API.
Invoices are transformed to the file layout your accredited provider expects (CSV or structured formats) and written to the agreed transfer folder or endpoint.
Your accredited service provider, such as Edicom, validates, maps to the mandated format (Peppol PINT AE for UAE, ZATCA structures for KSA), and submits to the tax authority.
Clearance and delivery responses (acceptance, rejection, UUID, QR data) flow back through status files and are written into your ERP so AR always shows the true regulatory state.
Inbound supplier e-invoices delivered by your provider from the Peppol network are collected from the incoming folder.
Each invoice is matched to your supplier master using agreed keys (VAT or TRN numbers, supplier codes), with duplicate detection on every run.
Matched invoices become AP entries in your ERP, ready for review through your existing approval process. Default GL coding rules are applied automatically.
Unmatched or failed invoices route to an exception queue with alerting, so poor supplier data degrades gracefully instead of blocking the flow.
Compliance rarely stops at the tax authority. Once an invoice is cleared, your customers still need to receive it, retrieve it and be notified about it. FloSynq orchestrates those internal steps in the same pipeline.
For each cleared invoice, the bridge can call your document repository (for example FileNet) to archive the invoice PDF for customer self-service, and your notification mail service to trigger the customer email. Because these systems sit inside your network, they are integrated by the same component that talks to your ERP, with the same idempotency and audit guarantees.
Archive cleared invoice PDFs (with QR codes where mandated) into systems like FileNet so customers can retrieve invoices through your portal.
Trigger customer notification emails through your internal business mail service the moment an invoice clears.
Update AR with clearance status and create AP entries from inbound invoices, so your ERP stays the single source of truth.
Regulators do not accept 'the integration dropped it' as an explanation. Every FloSynq e-invoicing flow ships with the same non-negotiables.
A re-run never duplicates a file, an extract, an AP entry, or an API call. Every invoice carries a deterministic key through the whole pipeline.
Every extract, file drop, pickup, status update and API call is logged with timestamps and payload references, ready for auditors and tax inspections.
Transient failures retry with exponential backoff. Persistent failures land in an error queue with alerting. Nothing is silently dropped.
An operational dashboard plus email alerts to nominated staff on failure conditions, alongside whatever monitoring your service provider offers.
A daily summary of invoices extracted versus statuses received, and inbound invoices received versus AP entries created. Gaps surface within 24 hours.
The bridge keeps your ERP side independent of the e-invoicing provider. If specifications change or you switch provider, your ERP integration carries over unchanged.
