Blink Business Accounting & Invoice Software

Blink is a lightweight business accounting and invoicing system built for freelancers, agencies, and small companies that need to send invoices, log expenses, and see real profit without wrestling with complicated desktop packages or monthly SaaS fees.

Create professional invoices with line items in seconds, mark them paid when money lands, track expenses by category and payment method, keep a clean customer list, and open a clear profit-and-loss view for the month, quarter, year or all time. Revenue-versus-expense charts, spending breakdowns and top-customer reports are built in, and you can export invoices or expenses as CSV whenever you need them. Everything runs in the browser, stores data on the device, works offline, and requires zero external database setup.

Ideal for operators who want professional books and fast invoicing without the complexity or recurring cost of traditional accounting platforms.

(Note after purchase: Buyers can contact us to specify their preferred fulfillment option—whether they want a branded standalone offline installer, online website integration, an offline + online sync setup, or the full source code.)
