End-to-End Invoice Flow
Contractors can generate branded invoices in seconds by adding line items, expense receipts, and banking coordinates.
Once submitted, invoices route to the finance administrator for verification and 1-click payout execution.
Automated Tax & VAT Calculations
Sferafy calculates invoice subtotals, applied VAT/sales tax rates, and net contractor payouts automatically, eliminating manual rounding errors across multi-currency line items.
Monobank monopay & ECDSA Verification
Invoices support instant online settlement via Monobank acquiring (monopay). Sferafy converts currency to ISO-4217 numeric codes (UAH 980, USD 840, EUR 978, PLN 985) and registers payments with invoice tracking references.
Webhook notifications verify cryptographic ECDSA SHA-256 signatures over raw request bodies using Monobank's cached public key, transitioning invoices to 'paid' status in real time and logging immutable audit events.
