Greenstamp is compliance infrastructure for accounting firms operating in countries where governments require electronic invoices to be approved in real time. The platform gives Mexican accounting firms a single workspace to manage end-to-end invoicing for 50 to 150 small business clients, including issuance, validation, review, official stamping
by tax authorities, payment receipts, credit notes, cancellations, and verification of incoming vendor invoices.
Built-in intelligence catches errors before invoices are submitted to the government, resolves product code lookups from plain-language descriptions, and translates rejection messages into clear explanations with suggested fixes. End clients are invited into white-labeled self-service portals, which removes the per-client workload that traditionally caps firm growth at whatever a single accountant can handle.
The strategy is Mexico as the wedge, global as the expansion. The same multi-country architecture that handles Mexican compliance is built to support electronic invoicing networks across Europe, Asia Pacific, and the rest of Latin America, positioning Greenstamp against the global wave of e-invoicing mandates governments are rolling out through 2030. Go-to-market is firm-led: one accounting firm brings dozens of end clients onto the platform at near-zero acquisition cost, with a path to convert growing client businesses into direct subscriptions over time.
