The post explains that e‑invoicing success hinges on technical validation, especially schematron rules, rather than just electronic transmission. It highlights how failures in these rules can delay payments, increase DSO, and create manual intervention for AP teams. The author plans to share deeper insights into validation and integration in future posts.

Key Takeaways
Schematron validation rules are XML-based checks that ensure an e‑invoice contains all required fields, correct tax codes, and structured data; they determine whether an invoice is legally valid, technically accepted, and payable.
If an invoice fails a schematron rule, it can be rejected before reaching Accounts Payable, leading to delayed payments, longer DSO, manual interventions, and payment disputes.
The author intends to share insights on schematron rules, validation layers, and integration architectures, focusing on how these technical details translate into real value or risk for AR/AP teams.
