Simple Estimates & Invoices
A private, phone-friendly app that helps a one-person plumbing and heating business in Whitehall, New York create professional customer documents without dragging field work back to a desktop.
Field work needed a simpler document process
A one-person trade business does not need a complicated office platform. It needs estimates and invoices that can be created quickly, look professional, and remain easy to find later.
The app also needed to work from the devices already in use, remain useful when internet access was unreliable, and reduce retyping when an estimate became an invoice.
A focused tool with only the features the business needs
The system was designed for two or three approved devices and avoids the overhead of a general-purpose accounting platform.
