ERP integration and data preparation — 1 to 4 weeks
Your ASP connects to your ERP via API. This is the technical integration — usually 1 to 2 weeks for modern systems such as SAP, Oracle, Odoo, or Dynamics. In parallel, your team reviews your customer master data: checking buyer tax numbers, verifying company names, and collecting Peppol IDs from your buyers. This data preparation often takes longer than the technical integration.
