We believe that billing your clients should be straightforward, beautiful, and completely private — never trapped behind steep monthly paywalls.
At Flow Bill, we understand that managing billing can be one of the most frustrating aspects of independent freelance careers and small business growth. The market is saturated with bloated, complex accounting packages that target large corporations, demanding steep monthly subscription packages and collecting sensitive operational data.
We decided to build a focused alternative. Flow Bill is a lightweight, high-performance browser utility that lets you craft pristine A4 invoices in seconds. There are no corporate accounts to sign up for, no data pipelines tracking your transactions, and no hidden features locked behind premium memberships.
Flow Bill is guided by three fundamental software principles designed to provide the best possible experience for small business owners.
We do not store your data. Your clients, line items, and billing calculations remain entirely on your local machine, processed in memory. Your privacy is mathematically guaranteed.
We do not believe in locking basic corporate functions behind premium walls. There are no credit card checks, no watermark layouts, and no limits on your growth.
No tedious registrations, no surveys, and no setup paths. Open the website on any device, fill out your items, and print a professional invoice immediately.
