Someone Venmo'd you half of last Friday's dinner. The rest is still out. If you mark the whole bill settled, you erase money that hasn't moved yet. If you delete the split and start over, you lose the history your group was using.
When you need to record a partial payment on a bill split on iPhone — half now, cash later, or one person first — SplitSnap lets you log what actually cleared and refresh who-owes-whom without zeroing the ledger. This is the natural next step after you already keep a running balance for your friend group.
Why a full settle-up fails when someone only paid half
Friend money almost never arrives in one clean transfer. One person sends half on Venmo. Someone else pays cash at brunch. A roommate covers their share of a trip leftover early. The group still has a remainder — and that remainder is still real debt.
A full 'settle up' that zeros everyone assumes the cash already matched the balance. When it didn't, you get one of two bad outcomes: the app thinks you're even when you're not, or you throw away the split and rebuild it from memory. Neither is how you want to settle up half with friends.
Part-payments keep the same group and the same debts — they only shrink what's left, the way money actually moved.
Open the balance from Home, a person, or the group page
Start from wherever you already see the IOU. On Home, tap the person who still owes (or who you still owe). From a person's page, open the open balance with that friend. From a group page, open the member whose line still shows a remainder.
You're not creating a new expense. You're updating an existing who-owes-whom line after money moved outside the app — Venmo, cash, bank transfer, whatever your crew uses.
Record a part-payment: amount, who paid whom, optional note
Choose record a part-payment (or the settle / payment flow your build labels for partial amounts). Enter the amount that actually cleared — half of Friday's dinner, $40 of a $90 trip leftover, whatever hit your account. Confirm who paid whom so the direction matches reality.
Add a short note if it helps later: 'Venmo half of sushi', 'cash at brunch', 'trip leftover — Maya early'. Notes are optional, but they stop arguments about which half was which when three payments stack in one week.
Amount = money that already moved, not the full original split
Direction = who paid whom, matching Venmo or cash
Note = enough context that next week's you remembers
Watch balances refresh on Home, Reports, and the group page
After you save, SplitSnap should refresh the live balances — not invent a second parallel ledger. Check Home: the person's line should shrink by the amount you logged. Open Reports if you use them for the month's picture. Open the group page: the same members, same group, updated remainders.
That refresh is the point of SplitSnap part-payments. You're not restarting the tally. You're telling the running balance that some cash already cleared.
Settle several people in one pass
Sometimes two friends each Venmo you a piece of the same night, or you pay two people back after a trip. Record each part-payment separately so each person's line updates correctly. Don't lump unrelated remainders into one fake 'settled' total — keep the payments tied to the people who actually moved money.
One pass can mean several part-payments in a row. That's fine. What you want is every real transfer reflected once, with the remainder still visible for whoever hasn't paid yet.
Real cases: Venmo half, trip leftover, roommate early
Venmo half / cash later. Friend sends half after dinner. Record that half as a part-payment. Leave the other half open until cash (or another Venmo) arrives. Don't mark the whole night settled.
Trip leftover. The big Airbnb split is already in the group. One person pays their share of the leftover groceries early. Log that part-payment against their line; everyone else's remainder stays until they pay.
Roommate pays a share early. This is not the same as setting up recurring rent. It's a one-time early payment against an existing shared expense in the group. Record the amount; keep the group so later payments stack on the same page.
Mistakes that wipe the ledger
Don't delete the original split because someone paid half. Deleting removes the shared history the group was using. Don't re-add a fake expense for 'payment received' that doubles the math. Don't mark everyone settled when only one person paid. And don't start a brand-new group just because money moved — that's how you lose the running balance.
Don't delete the split after a partial
Don't invent a second expense that mimics a payment
Don't full-settle when cash only covered half
Don't abandon the group and restart from zero
When the remainder clears — and how to check history
When the last piece arrives, record that final part-payment (or complete the settle for the remainder). The person's line should hit zero. Glance at history so you can see the half, then the rest — useful if someone asks 'did you get my Venmo?' two weeks later.
If something looks off, fix the last part-payment rather than rebuilding the whole night. Small corrections beat a wiped ledger.
Keep using the same group so payments stack
Part-payments only stay useful if the crew keeps living in one group. Tag new dinners and trips to the same page you already used for the running balance. Then every Venmo half, cash later, and early trip share stacks on the same who-owes-whom lines instead of scattering across chats.
For the setup that makes this possible — one group, members, live balances across nights — start from the friend-group running balance walkthrough, then come back here whenever money moves in pieces.
