Group Trip Cost Split and Booking Audit

Check fairness and deadlines in shared plans.

Added October 15, 2026. Written with AI assistance and checked for clarity and placeholders; not reviewed by a lawyer, accountant, clinician or other professional. How these prompts are made

The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.

[VERIFY] is an editorial flag, not a blank to fill. Wherever the prompt shows [VERIFY], check that item against a reliable source before you use it (what [VERIFY] means).

Audit a group trip's costs and bookings. Booking list, who paid what, deadlines and the split method: [GROUP_TRIP_DATA]. Group members' circumstances I am allowed to share: [MEMBERS]. Cancellation terms: [TERMS].

Recalculate who owes whom, check that the split method matches what was agreed, find bookings at risk of missing deadlines, and propose a clear payment schedule. Treat agreements as questions to confirm with the group.

Return a table with Person, Paid, Share and Balance, a schedule, and a message to the group under 120 words. Refund and cancellation rules are [VERIFY].

Also suggest using a shared sheet with receipts attached, agreeing how to treat optional activities, and settling up within a week of returning. Add a template for a friendly reminder message and a reminder to keep discussions about money respectful.

Treat prices, opening hours and transport times as unconfirmed. Tag them [VERIFY] and name the official source to check before I book or pay for anything.

End with a one-page action plan under four headings: stop, start, change and keep, each with no more than three items.

Fill in before use

Optional: type your details and the prompt above updates. Nothing is saved or sent.

Replace each bracketed placeholder with your own details, then paste into Any AI or another assistant.

Recalculation (invented, 5 travellers, 3 nights)
Paid: Sam 900 (house), Ria 142 (food), Lee 210 (car). Total 1,252; equal share 250.40.
Balances: Sam is owed 649.60. Ria owes 108.40 (142 minus 250.40). Lee owes 40.40. The other two owe 250.40 each.
Check: 108.40 + 40.40 + 250.40 + 250.40 = 649.60, which equals what Sam is owed.
Risk: the house balance is due in 14 days; two people have not paid.
Message (under 120 words): "Thanks for a great weekend. Costs came to 1,252, or 250.40 each. Please send your balance to Sam by Friday; the table is attached. Shout if anything looks wrong."
Refund and cancellation terms: [VERIFY].
