A Shared Child Expense Tracker for Co-Parents

School supplies, medical bills, summer camp, birthday gifts โ€” child expenses add up across both households. DuetNest lets a parent add an expense, attach a receipt, choose a split, and keep the family-space balance in one place.

Why splitting child expenses is so painful

Generic expense apps are not always organized around long-running child expenses. A family may need custom percentages, receipt attachments, child tags, comments, settlements, and a record that both participating adults can review. DuetNest keeps those user-entered details in the shared family space.

Attach or enter manually

Enter expense details manually and optionally attach a receipt. If you explicitly request AI receipt reading, DuetNest prepares editable draft fields that you review before saving.

Choose how to split

Default to 50/50, set a custom percentage, or assign 100% to one parent. Per-expense overrides are easy.

Co-parent reviews

The expense appears in the family space with a review status. Participants can comment or flag missing information for clarification.

Settle when ready

The running balance shows the recorded amount between parents. Add a settlement payment and the balance updates by that amount.

Receipt photos preserved

A receipt image can be attached to an expense so the source document stays with the record.

Custom split ratios

Set 60/40 or any percentage to match a formal agreement or income difference.

Multi-currency support

Travel and international families can log expenses in the original currency.

Clean exports

Available PDF exports and companion JSON organize selected records for review. Users remain responsible for checking whether an export meets a tax, mediation, or legal requirement.

Frequently asked questions

Can I set a non-50/50 split?

Yes. Each expense starts at 50/50 and can be changed to a custom percentage for that expense.

How does receipt scanning work?

Receipt scanning is optional. After you request it, AI prepares editable draft fields. Review every field before saving, or enter the expense manually without AI.

How do we settle balances?

DuetNest tracks the balance in-app โ€” you settle by your preferred method (Venmo, bank transfer, cash) and mark it paid in the app.

Can I export expense records?

DuetNest provides expense export options for organized review. Check the generated file and any local tax, mediation, or legal requirements before relying on it for a formal purpose.
