Event cashbox
Manage participants, deposits, budgets, expenses, payment methods, receipt photos and the final settlement for a time-limited event.
SiMaDoo
Shared money. Separate payments.
SiMaDoo combines a shared cashbox, event expenses and a fair final settlement. Nobody needs to keep a private debt list.

Take your data with you
Settlements and cashbox data can be exported as a clear PDF or a structured Excel file – ready to share, save and process further.
The problem
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
One app, three views
Manage participants, deposits, budgets, expenses, payment methods, receipt photos and the final settlement for a time-limited event.
Track members, roles, cash and account balances, contributions, penalties, donations, contributions in kind, tasks, partial payments and cancellations.
Several people can pay during the same event. SiMaDoo includes every payer in the final calculation and keeps private debts out of the settlement.

Personal access. Clear roles.
Every invited community member and event participant receives free personal access on their own smartphone or on the web. They see the information and functions assigned to their role.
Shared cashbox
Manages the shared cashbox, members, settings and settlement.
Shared cashbox
Use their own linked access and see the cashbox information shared with them.
Event
Manages the event, participants, settings and planning.
Event
Use their own access and record or view event data according to the event settings.
Invited members and participants do not need their own paid plan for personal access.
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.
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
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.
