ViDA (VAT in the Digital Age) is gradually forcing the whole EU toward mandatory structured e-invoicing. We connect you to PEPPOL, ISDOC and KSeF with the same durable architecture — idempotent, with reconciliation and an audit log, not a fire-and-forget script that silently drops invoices.
E-invoicing looks like "call an API and send XML." In practice it's an asynchronous system with its own state, rate limits and outages — and when that's underestimated, invoices go missing silently, for months, before anyone notices.
Sending invoices without persisted state and retry logic looks like it works, until the PEPPOL access point or KSeF has an outage. Then you find out thousands of documents are silently missing — and nobody knows, because nobody built reconciliation.
Cross-border B2B e-invoicing under EN 16931 is mandatory from July 2030, with national regimes set to align by 2035. Companies that leave this until right before the deadline discover their ERP and invoicing system aren't ready for structured data at all.
Idempotence, retry with backoff, rate limiting, reconciliation, an audit log — that's engineering work, not a plugin configuration. Project management earns its keep on a large multi-system program; for a single e-invoicing integration, direct access to the architect who actually builds it is the faster path.
We build PEPPOL access point, ISDOC exchange or ViDA digital reporting connections as a durable, auditable system — not a script that sends XML and hopes. The exact approach that's processed over 40,000 KSeF documents in production with 100% delivery.
Every submission carries a deterministic idempotency key and persisted state. A PEPPOL access point or KSeF outage doesn't mean a lost invoice — it means a queue that retries automatically.
External e-invoicing systems have their own limits and can be unreliable. Retry with exponential backoff and rate limiting against the foreign API are part of the architecture from day one, not a patch after the first outage.
A periodic check of "does reality match what we think we sent" — no silent orphan documents, no stuck states nobody notices for months.
An anti-corruption layer wraps the quirks of each format and system (PEPPOL access point, Czech ISDOC, Polish KSeF) so they don't leak into your business logic. One architecture, three targets.
E-invoicing integrated into Dynamics 365 Business Central and other ERP and invoicing vendors — not an isolated tool on the side, but part of the existing invoicing process.
The build is led by the same architect who built the KSeF integration and forensically recovered 15,141 invoices lost by the previous pipeline — not a team learning ViDA and PEPPOL on your project.
The KSeF integration this architecture is built on runs in production and has submitted over 40,000 documents with 100% delivery. When a previous fire-and-forget pipeline silently dropped invoices, forensic analysis recovered 15,141 missing documents — and the same durable machinery that rules out that kind of loss is carried over to the PEPPOL access point and ViDA digital reporting. The integration also runs into Dynamics 365 Business Central.
We'll tell you whether your ERP and invoicing flow are ready for PEPPOL, ISDOC or the upcoming ViDA mandate, and what a durable integration without the risk of silently lost documents would look like. We'll reply within 24 hours with a concrete recommendation.
