Meet the Developer
of Invoice 4 Business

As a successful Amazon entrepreneur, Edward Kellman realized his accounting tasks were taking too much of the valuable time he needed to run his business. The app solutions he found online offered partial solutions, but none contained all the accounting features his company required.

Edward, an engineer with an MS in Engineering from the University of Michigan, put the programming skills he developed for his Amazon business to use. Assuming other business owners were in the same predicament, he developed a complete package of accounting software solutions that no other apps provided.

The missing piece was a double-entry multi-extrinsic-variable accounting method with additional columns. This complex-sounding solution, formally patented (US 11,397,930.) as extrinsic variables, translates to an easy-to-use accounting solution applicable to any business.
