About

SmartInvoice is a free, ad-free invoicing and payment-tracking SaaS built for freelancers, creators, independent professionals, and small businesses.The product offers two ways to create invoices: Simple Invoice for quick billing and Professional Invoice for detailed, client-facing invoices with itemized line items, taxes, discounts, due dates, payment details, custom fields, branding, and multiple templates.Users can record full and partial payments, track outstanding and overdue balances, manage clients, view invoice and payment history, and follow up with automatic and manual payment reminders. The platform also includes dashboards, reports, activity tracking, PDF/print functionality, and an installable experience for mobile and desktop.SmartInvoice is fully deployed and operational, with a production frontend, FastAPI backend, PostgreSQL database, authentication, email integration, scheduled automation, and documented infrastructure.The project is currently pre-revenue and is being offered as an acquisition opportunity. The core product is already built, so the main opportunity for a new owner is customer acquisition, distribution, and monetization rather than building the product from scratch.SmartInvoice — Create.
