The Simplest Child Expense Tracker for Co-Parents

School supplies, medical bills, summer camp, birthday gifts — child expenses add up fast and across both households. DuetNest's expense tracker is built specifically for shared parenting: snap a receipt, choose a split, and the running balance updates instantly for both parents.

Why splitting child expenses is so painful

Generic expense apps like Splitwise are built for roommates and trips, not co-parents who share expenses for years. Receipts get lost, the split percentage isn't always 50/50 (court orders often define different ratios), and there's no audit trail when one parent forgets to log something. Co-parents need a tracker that handles real-world complexity: court-ordered split percentages, recurring expenses, receipt photos, multiple children, and a clean export when tax season or a custody review comes around.

Snap or type

Take a photo of any receipt — the AI reads the amount, vendor, and date automatically. Or type a one-line description.

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 other parent gets a notification. They can approve, comment, or flag for clarification.

Settle when ready

The running balance shows exactly who owes what. Mark a payment settled and the slate is reset.

Receipt photos preserved

Every expense keeps the original receipt image, so there's never a 'did you actually spend that?' conversation.

Custom split ratios

Set 60/40 or any percentage to match a court order or income difference.

Multi-currency support

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

Clean exports

PDF or CSV export of any date range — ready for taxes, mediation, or court.

Frequently asked questions

Can I set a non-50/50 split?

Yes. Set a default split for your family (e.g., 60/40 based on income) and override per expense if needed.

Does receipt scanning really work?

Yes. Our AI handles printed and handwritten receipts, including international formats. You can always edit the result.

How do we settle balances?

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

Can I export for taxes?

Yes. Export any date range as PDF or CSV with full receipt photos attached.
