How VExpenses scaled the verification of 150,000 tax invoices per month
Manual validation could not keep up with volume and exposed operations to inconsistent documents. Magical built an API connected to official databases to automate checks and issue evidence of document integrity.

Project results
- 150k/monthtax invoices with automated verification
- Monthly volume processed through the tax workflow connected to state databases for VExpenses clients.
- Official databasedocuments checked in real time through SEFAZ
- Queries made to the relevant state tax authority during the validation of processed tax documents.
- Certificateevidence of integrity issued for the document
- An artifact issued by the workflow to support integrity checks; it is not an external guarantee against fraud.
The problem
Latin America's largest corporate expense and travel management platform processes over 150,000 tax invoices each month, submitted by employees at more than 5,000 client companies. Manual receipt validation was slow, exposed to fraud and unable to keep up with tax compliance requirements.
What Magical did
Tax invoice validation system with multiple capture methods
Integration with the tax authorities (SEFAZ) in every Brazilian state
API designed for high-volume cloud processing
The impact
Over 150,000 invoices per month validated automatically, in seconds
Documents checked against official databases in real time, reducing exposure to inconsistent receipts
Integrity certificate issued as evidence to support tax document verification by VExpenses clients
