SquareUsUp is an intuitive and comprehensive premade Excel spreadsheet to help a group split and track its shared expenses.

The most popular expense-sharing apps are powerful, but they’re not for everybody. They may charge you money. They may have ads. They may keep your private financial data on their servers. They may want your whole group to download the app and sign up to use it.

Countless spreadsheets available online provide rudimentary expense-sharing features. But not one is a complete and foolproof expense-sharing solution.

SquareUsUp is a free Excel spreadsheet that can be learned in minutes, requires no Excel knowledge, and elegantly implements every essential feature a serious group expense-sharing app must have.

(And it’s totally free.)

Effortless, powerful group expense sharing.

(If you’ve got 4 minutes, we’ll show you.)

A full-featured app inside a spreadsheet.

Virtually all expense-sharing spreadsheets work by placing clever Excel formulas into simple sheet layouts. While these solutions are good at demonstrating Excel techniques, they all have primitive user interfaces, they lack vital expense-sharing features, they don’t scale well to larger projects, and they don’t offer protection from cascading Excel errors.

SquareUsUp is a full-featured app built inside the Excel runtime environment. Its architecture includes a data-validation and computation engine implemented via a complex web of Excel formulas, plus a sophisticated user interface implemented via extensive VBA code. These two subsystems provide a full suite of expense-sharing services while insulating the user from Excel’s complexities, making SquareUsUp a worthy alternative to the most popular expense-sharing apps.
