What is the clearing model for e-invoicing and which countries use it?
The clearing model requires invoices to be submitted to and validated by a tax authority platform before they can be issued to the buyer. The tax authority acts as a clearinghouse for all invoices. Saudi Arabia (ZATCA), Turkey (GIB), and Brazil (SEFAZ) operate clearance models. In contrast, the post-audit model allows invoices to be issued freely and checked by authorities after the fact. The UAE is implementing a clearance model for B2B invoices.
How does clearance differ from the post-audit e-invoicing model?
Clearance model: Invoice submitted to tax authority before issuance; authority validates and stamps; stamped invoice issued to buyer; tax authority has real-time data. Post-audit model (also called reporting model): Invoice issued freely to buyer; data reported to authority within a defined period (e.g., 24-72 hours); authority cross-checks after the fact. Clearance provides stronger real-time controls; reporting provides more flexibility. Italy's SDI uses a variant combining clearance-style central routing with post-audit-style timing.
Frequently Asked Questions
- How does the clearance model affect invoice issuance speed?
- Modern clearance models are designed to add minimal latency. ZATCA clearance for a properly formatted invoice typically takes seconds. However, clearance requires real-time API connectivity and can be delayed by network issues or tax authority platform congestion during peak periods. Businesses must design their invoicing workflows to handle clearance latency, particularly for invoices issued at the point of delivery where timing is critical.
- What is the difference between pre-clearance and post-clearance CTC models?
- Pre-clearance (true clearance): Invoice must be cleared before being legally effective; it cannot be issued to buyer without clearance. Post-clearance (reporting model): Invoice is issued to buyer immediately and simultaneously reported to the tax authority within a required window (e.g., 24 hours). Italy's SDI sits in between: the invoice is sent through SDI which routes it to the buyer, functioning as central delivery with near-simultaneous data access by the tax authority. Brazil's NF-e is pre-clearance; Portugal's ATCUD is closer to reporting.
