UAE eInvoicing is now mandatory
Starting January 2027, every UAE business with revenue above AED 50M must send invoices electronically through the Peppol network. Non-compliance carries penalties of up to AED 5,000 per month, with additional fines of AED 100 per late invoice.
Three steps to compliance
One invoice or ten thousand. Same process.
Upload Your Way
Drop a single invoice PDF or batch-upload thousands via API, SFTP, or CSV. Connect your ERP for fully automated submission.
Auto-Parse & Validate
180+ validation checks run instantly. EN16931 schema compliance, UAE TRN verification, VAT calculations, and field completeness. Errors flagged with plain-language fix instructions.
Transmit via Peppol
Peppol-ready PINT-AE XML generated and transmitted to the FTA through our certified ASP. Track clearance status in real time from your dashboard.

180+ Pre-Submission Validations

ASP selection deadline. Same registration process on EmaraTax portal.
Full mandate in effect. Every UAE business must comply regardless of revenue.
What changes for your team?
Less than you think.
Your finance team
Invoices are generated from the same data they already produce. The only change: invoices route through Calculus for validation and Peppol transmission before reaching the buyer. Most teams are fully comfortable within the first week.
Your IT team
For API or SFTP integration, expect 2-4 weeks of setup with our documentation and integration support. For file-based upload, no IT involvement is needed at all.
Your customers
They receive the same invoice, now with a Peppol-compliant XML attached. No action required from their side until their own mandate deadline arrives.
Average time to go live: 3-6 weeks from contract signing.
