Fáctil is the Mexican app that helps you download your invoices from the SAT (Mexican Tax Administration Service) in just a few taps and truly understand how your business is performing. No more complicated Excel spreadsheets, no need to rely on your accountant for basic tasks, and no more worrying about income tax or VAT.
Everything is saved on your phone. Your e.firma (electronic signature) is never permanently uploaded anywhere—it's only used the exact moment you request your invoices from the SAT.
⚡ WHAT Fáctil DOES FOR YOU
📥 Bulk SAT Download
Connect your e.firma (.cer, .key, and password) and download ALL your issued and received invoices. Payroll, payments, credit notes, transfers—everything.
📊 Tax Dashboard
See in one place how much you sold, how much you spent, your profit, your margin, and your cash flow month by month. With easy-to-understand graphs.
💰 Income Tax and VAT Calculator
Estimate how much you'll pay each month in income tax and VAT. Current rates from Article 96 of the Income Tax Law (LISR), updated table, no surprises at the end of the month.
🧾 Payroll Analysis
Verify if your employer is withholding income tax correctly. If they under-withheld, you'll know how much to reserve. If they over-withheld, you'll know how much you're entitled to.

📌 IMPORTANT
Fáctil is NOT an accounting firm and does not replace your accountant. It is a tool so YOU have the information at your fingertips when you need it — before, during, or after your tax return.
The e.signature you upload to the app is yours and yours alone. The app only uses the app when you request it to download invoices from the SAT (Mexican Tax Administration Service). This information is never shared or stored on the developer's servers.
