Where to start

JDG should start by reviewing the invoice tool and determining whether the current system supports KSeF without additional manual workarounds.

The next step is to prepare a simple checklist of daily work: issuing an invoice, correction, status verification.

  • Check the readiness of the current system.
  • Prepare step-by-step instructions.
  • Designate a contingency plan.

The most common JDG errors

The most common problems are the lack of current contractor data and omission of correction tests. It is the corrections that cause the most stress after the start.

The second common problem is the lack of status monitoring and delaying response to errors until the end of the month.

  • Invalid buyer details.
  • No adjustment tests or exceptions.
  • No daily status monitoring.

A minimum set of good practices

The simplest model is 15 minutes a day to check statuses and 1 hour a week to review rejected documents.

This is enough to avoid the accumulation of errors and sudden crises at the end of the accounting period.

  • Daily status review.
  • Weekly review of exceptions.
  • Monthly update of the procedure.
