Contalink

Contalink is a Mexican cloud accounting and payroll platform ("contabilidad en la nube") built for independent accountants, accounting firms (despachos) and SMEs. It automates repetitive Mexican fiscal work — bulk CFDI download and classification, electronic accounting, DIOT preparation, treasury and bank reconciliation, invoicing (facturación) and payroll (nómina) with digital stamping — across multiple companies and users. Contalink also exposes a REST API that lets external systems read and post accounting data: trial balance (balanza de comprobación), account balances, manual accounting policies (pólizas manuales), invoice reconciliation (conciliación), bank transactions (movimientos bancarios) and CFDI fiscal-document listing, upload and status checks. The API authenticates with a per-company API key sent in the Authorization header. Backed by 500 Global.

Contalink publishes 8 APIs on the APIs.io network, including Balanza de comprobación API, Cargar un documento fiscal API, Conciliación API, and 5 more. Tagged areas include Company, Accounting, Bookkeeping, Payroll, and Tax.

Contalink’s developer surface includes API reference, documentation, getting-started guide, support, engineering blog, pricing, signup flow, and 11 more developer resources.
