Small business relies on Big Tech software

So why doesn't Big Tech deliver simple inexpensive software for business management?




No technical reason...

Managers routinely set up spreadsheets, forms, and reports that already specify everything necessary to their business system. Creating a program to gather this information into a fully-linked management program is far easier than creating the Internet, smart phones, the Metaverse, and AI.

Big Tech could have delivered it 20 years ago.

The reason is marketing; it's a multi-billion dollar business...

business management software sales are an estimated USD 700 billion dollars per year. Much of this is unnecessary.



Software for Small and Medium Enterprises and Organization (SMEOs) is written as if a junior version of management software for large enterprises.

The needs of SMOEs, however, are entirely different. They need transparency, low-cost, and flexibility.

Large enterprises usually need sophisticated systems analysis. Managers at SMEOs are already expert in their own needs; all they need is a simpler way to apply their expertise.

If you had a way to pick up the information already in your spreadsheets and management experience, you could build your own management program.

It might look like this:




This 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.




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 platform.
