Keep group money clear, even when everyone pays separately

The problem

A group shares the plan, but not every payment

One person pays by card, someone else pays cash and the group may already have money in a shared cashbox. SiMaDoo records what actually happened and calculates the result for the group.

How it works

Five clear steps

  1. You are a group.Add participants or members and assign the appropriate roles.
  2. You use shared money.Record the cash, account and total balance of your shared cashbox.
  3. You plan something together.Create an event, set its period and optionally connect a shared cashbox.
  4. You still pay separately.Record deposits and expenses, including the payer, payment method, notes and an optional receipt photo.
  5. SiMaDoo calculates the result.See what remains, who still needs to pay in and who receives money back from the cashbox. Nobody owes another person privately.

Use only what your group needs

Event cashbox

Manage participants, deposits, budgets, expenses, payment methods, receipt photos and the final settlement for a time-limited event.

Shared cashbox

Separate expenses

Several people can pay during the same event. SiMaDoo includes every payer in the final calculation and keeps private debts out of the settlement.

Free for invitees

Invited members and participants do not need their own paid plan for personal access.

Optional free recovery

When creating a cashbox, or later in settings, access can optionally be secured with a verified email address and password. This allows cashboxes, events and roles to be restored after changing devices or reinstalling. Recovery is not possible without secured access; this is not a standalone backup service.

Transfer cashbox management securely

Current cashbox management can be transferred to an active member who is already connected to SiMaDoo through an invitation. That person receives management rights; the previous manager remains a regular community member.

Free use

3 months free from your first cashbox start

Your three free months begin when you first open the cashbox feature. Start and end are stored securely; reinstalling, changing devices or recovering access does not restart the period. Invited community members and event participants continue to use personal access free of charge according to their role.

Information about later prices will be announced only after separate approval.
