See everything factsimil includes, with real screenshots →Your online store, already included
A public storefront, a cart, and WhatsApp checkout — wired to the same inventory and the same invoicing you already use. No per-sale commission, no separate platform to maintain.
Your catalog, on your own link
Turn on your public storefront and your published products show up at factsimil.com/tienda/your-business.
Your customer builds their order
A simple cart and checkout — no account required on their end.
Stock updates on its own
The same Kardex you use for purchases and counter sales updates with every order.
You confirm the sale, not a bot
Every order lands in your Pedidos inbox. Nothing invoices itself.
Straight into your accounting
Invoice with the customer and products already loaded from the order — no re-typing anything.
Take factsimil with you
Issue invoices, check on Guías, and get an instant push notification the moment SUNAT resolves a document — straight from your phone.
Direct APK, v1.0.0 — not on Google Play yet. Android will warn about installing from outside the Play Store; that’s expected.
