is a

simple, inexpensive, open source

business management and accounting solution.

No IT experience required.




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

You routinely set up paper-based or spreadsheet-based forms and reports. Together these forms and reports fully describe the business. All you need is a way to harness your knowledge.

SUMER gathers that information and seamlessly builds a complete management and accounting application using only skills familiar from basic spreadsheets.

No software vendors, no salespeople, no modules, no cost to add new users. Sumer builds a sophisticated management system surpassing that of expensive software suites while requiring absolutely no knowledge of IT,




Who needs Sumer?


Sumer is designed for most Small and Medium Enterprises and Organizations (SMEOs) that need to keep up with the ever increasing pace of business.

SMEOs have special needs:

  • no specialized IT staff or outsized IT expenses,
  • flexibility to meet changing demands without seeking out entirely new software,
  • an intuitive software interface so they can devote time to business rather than mastering complex technology.

Any business planning for growth, or fed up with poor software solutions, or still using spreadsheets to track business data should consider Sumer.




Why you need Sumer


Sumer solves a problem experienced by millions of businesses: available management software is over-priced, overly complex, and inadequate.

Software purveyors often tie customers into expensive contracts, subscriptions, charges to add new users, and an endless queue of proprietary expansion modules. The cost of software alone can be prohibitive.

And yet trying to use a mix of Excel, Google Docs, Quicken, and a whole fleet of other apps is a frustrating and wasteful piece-meal solution.
