is a

simple, inexpensive, open source

business management and accounting solution.

No IT experience required.




Why has Big Tech failed to deliver appropriate software for small and medium businesses?




No technical reason . . .

As a manager, you are an expert at how to run your business.

You routinely set up spreadsheets, forms, and reports. Creating a program to gather this information should not be difficult, but Big Tech skipped that next step after Excel and jumped ahead to the more exciting tasks of building the Internet, smart phones, Big Data, the Metaverse, and AI.


The reason is marketing . . . selling business management software is a 700 billion dollar per year business.




If you had a simple way to pick up the information already in your spreadsheets, you could build your own management program without salespeople and expensive subscription packages.

It might look like this:




This wholesale nursery automates Purchase Orders, Receiving, Inventory, Sales, Accounting and more.





This craft brewery places Purchase Orders, tracks Receiving, uses a Bill of Materials to automatically update Inventory in Brewing, posts Inventory value to Accounting at End-Of-Period, tracks Kegs by batch and with customers.





This cafe uses a table chart to open and close guest dockets.





Sales, purchases, end-of-period inventory values all post automatically into a complete accounting app.





This business uses a variety of timecard, timeclock, and shift scheduling apps.





All these businesses use Sumer to build their entire management system without any knowledge of IT or coding.




Set-up is simple:

  • Forms are built with a spreadsheet-style interface that looks exactly like the underlying form,

  • Menus are built with drag-and-drop and can be customized down to an individual user level,

  • That's all.

Sumer believes business management software should cost 10% of its current price, be far more comprehensive, and be based on an open source peer-to-peer community.
