WHY SOLO BIZ OPS

100% Offline, Always No servers. No accounts. No internet required, ever. Every calculation, every invoice, every client record lives only on your device. Your financial data is yours — completely private, completely secure.

Built for Real Freelance Work Most invoicing apps are built for small businesses with full-time staff. Solo Biz Ops is built for one person doing it all — the rate calculator accounts for unpaid leave, public holidays, and overhead the way an actual freelancer thinks about pricing.

Multi-Country Support Switch between India, the United States, the United Kingdom, and Australia. Tax brackets, GST/VAT rates, currency formatting, and public holidays all adjust automatically to match where you work.
