From job-site frustration to free software for everyone.
FatturaFacile was born between Lombardy and Swiss Canton Ticino with a clear purpose: freeing tradespeople, micro-businesses, and solo professionals from bloated ERPs and unending SaaS subscriptions.
Why should someone issuing 15 invoices a month pay for a 500-button ERP?
It all started at a workbench, watching fellow tradespeople and small business owners struggle late at night with sluggish, over-complicated web portals just to get paid for their craft.
The Frustration with Over-Engineered Enterprise Software
An electrician, plumber, carpenter, or independent consultant does not need to manage a multinational supply chain or complex double-entry corporate ledgers. They need to draft a clean quote in 60 seconds while still on-site with the client and convert it into a legally compliant invoice in a single click.
The Anti-SaaS Philosophy: Your Data Shouldn’t Be Held Hostage
In recent years, small-business software has turned into a permanent rental trap: stop paying the monthly fee, and you lose the ability to operate or even access your own customer history. We believe your tools and financial records must belong 100% to you—with no expiration dates and no vendor lock-in.
“Invoicing software for tradespeople should work like a reliable screwdriver in your toolbox: ready the instant you need it, never asking for a monthly subscription to turn a screw, and working flawlessly in a basement with zero cell reception.”
Traditional SaaS / Enterprise ERPs
- ✕Mandatory monthly or annual subscriptions that increase every renewal cycle
- ✕Cluttered dashboards with hundreds of buttons micro-businesses never touch
- ✕Complete dependence on internet connectivity and slow cloud page loads
- ✕Customer lists and sensitive billing data stored on third-party servers

Rock-Solid Engineering Serving Everyday Simplicity
Beneath a deliberately minimalist interface lies a software architecture built to the highest standards of data sovereignty, speed, and reliability.
Local SQLite & Zero Telemetry
No tax ID, IBAN, or customer record ever leaves your machine. The business owner remains the sole Data Controller under EU GDPR and Swiss FADP (nLPD), eliminating third-party data breach risks.
- ✓Single-file ACID transactional SQLite database
- ✓Zero telemetry calls, analytics, or background tracking
- ✓1-Click AES encrypted ZIP backups to USB or local NAS
Dual-Market Foundation: Italy & Switzerland
Unlike generic billing tools retrofitted with rough translations, FatturaFacile was engineered from day one to comply natively with the strict tax standards on both sides of the Italian-Swiss border.
- ✓Italy 🇮🇹: Certified FatturaPA v1.2 XML for SDI, PEC/Recipient Code, and virtual duty stamp
- ✓Switzerland 🇨🇭: Official SIX standard QR-Bill slips with Swiss cross, QR-IBAN, and federal VAT rates
- ✓Native multi-currency support for EUR and CHF
Clean Architecture & Native C# .NET
We rejected bloated web wrappers that consume gigabytes of RAM. FatturaFacile is crafted in native C# .NET using CQRS and SOLID principles, delivering instant responsiveness even on older workshop laptops.
- ✓Strict separation across Domain, Application, Infrastructure, and UI layers
- ✓Continuous quality gates powered by SonarQube and JetBrains Qodana
- ✓Optional Self-Hosted Docker edition for multi-user teams
