e-invoicing software

E-invoicing software: tax authority submission, status tracking and error handling

In short

E-invoicing software converts invoices into compliant XML, submits them to national tax authorities, tracks delivery status and handles rejections. Without real-time status tracking, a rejected invoice remains unrecorded by the client until a payment dispute arises, causing significant cash flow delays and compliance risks.

Who searches for this and why

The search for "e-invoicing software" comes from businesses facing technical friction: rejected invoices, stuck messages, or software vendors that only offer manual file uploads instead of native API automation.

What "e-invoicing"

e-Invoicing is the process of transmitting invoices electronically to national tax authorities in a standardized XML format (such as Peppol BIS 3.0 or EN 16931). An invoice is only legally valid once it receives an acceptance status from the tax portal; until then, it does not exist for the buyer or for tax deduction purposes.

The 5 most common validation errors

Almost all rejections stem from a few recurring issues, all of which can be prevented during the drafting stage.

  • VAT numbers or partner identification data that do not match official registries.
  • VAT rates incompatible with the declared type of transaction.
  • Missing mandatory legal mentions for reverse charges or tax exemptions.
  • Incorrect references to the original invoice when issuing a credit note.
  • Units of measure or product codes that do not comply with standard codification (UN/CEFACT).

Status tracking: the missing link in most solutions

Submission does not guarantee acceptance. CRMconnect periodically polls the tax authority APIs for status updates, marks documents as accepted, signals rejections with clear explanations, and allows for re-submission after correction, maintaining a full audit trail.

Beyond e-invoicing: the fiscal ecosystem

Fiscal workflows extend beyond the invoice: electronic transport documents (where required), SAF-T / statutory audit files, partner VAT validation, and payment reconciliation. All these run within the same system using the same source data.

  • Electronic transport documents generated directly from shipping notices.
  • Automatic partner validation via VIES and national VAT registries.
  • Automated bank reconciliation for incoming payments.
