Why trust factsimil

Not a demo — this is what already invoices today

Direct to SUNAT, no OSE

factsimil implements the SEE del Contribuyente scheme: it signs your receipts with your certificate and sends them straight to SUNAT. Your company remains the issuer — you enroll in the SEE and register your certificate with your SOL credentials, and we guide you through it.

In real production, every day

Not a demo: active businesses issue with factsimil daily, and another platform bills in production through our API.

Your certificate, encrypted at rest

The digital certificate (.p12) is encrypted at rest and only decrypted in memory the instant each document is signed.

Everything you need to issue electronic invoices

Facturas & boletas

Electronic invoices and receipts, fully compliant with SUNAT.

SEE del Contribuyente

Signed and sent directly to SUNAT — no intermediary OSE, no per-receipt fee.

Automatic XMLDSig signing

Every document is signed with your certificate, automatically.

Multi-tenant REST API

One integration, many businesses — built for platforms from day one.

Safe sequential numbering

Concurrency-safe series numbering, no gaps, no duplicates.

Certificates encrypted at rest

Your .p12 certificate is stored encrypted (AES-256-GCM) and only decrypted in memory to sign.

And there’s more

A full accounting ERP behind the invoice

Electronic ledgers (PLE, 11 books in SUNAT’s official structure), SIRE, weighted-average Kardex, budgets, and payroll (PLAME) — all from the same panel, no extra modules to integrate.

A full chart of accounts, from day one

Every new account starts with the complete PCGE (Peru’s standard chart of accounts) already loaded — over 1,700 accounts. No setup spreadsheet, no waiting on an accountant to configure it.

PLE — Electronic Ledgers, 11 books ready to file

Generates the files for SUNAT’s Programa de Libros Electrónicos with the field-by-field structure of the official Annex 2: Libro Caja (cash), Libro Diario and its chart of accounts, Libro Mayor, Registro de Compras, Registro de Ventas, the permanent inventory registers (units and valued) and three Libro de Inventarios y Balances sub-formats. Fixed assets and bank accounts are exported as review reports, not as PLE files. You upload the files to SUNAT — factsimil never sends or validates anything on your behalf.

Kardex — weighted-average inventory, updated with every stock receipt

Every stock receipt (a received purchase order or, on the Contable plan, a recorded purchase) creates the entry and recalculates the weighted-average cost of everything in stock. Every movement is logged with date, quantity, unit cost, and running balance.
