Welcome to Mamon, the new Point of Sale (POS) system designed specifically for E.S.R. Thêta.

Mamon is a redesign of the old POS system, Bacchus, with similar use, a new look and feel, as well as more advanced financial features. Mamon is designed to be used by both staff and members, and is (soon) available on both Android and IOS.

Mamon is currently in beta, and is being tested by the E.S.R. Thêta staff. If you are a Thêta member and want to test the client app, please login with your E.S.R. Thêta credentials to create an account, you should then be able to log into the client app.

If you want to test the staff app, you need to request access to Gustavo Maduro-Vollmer to get a staff account. Unfortunately, if you are not a E.S.R. Thêta member, you will not be able to test Mamon.

Should you have any other questions please feel free to contact Gustavo Maduro-Vollmer here.
