How to Split Shared Groceries With Roommates (2026) | Partly

Shared groceries are where roommate budgets go to die: one person buys olive oil for everyone, another only drinks oat milk, and the receipt sits in a coat pocket for ten days. You need rules plus a scan, not a lecture.

Draw the grocery line on day one

Communal: oil, salt, cleaning, toilet paper, agreed staples. Personal: branded snacks, special milk, protein powder, alcohol unless everyone drinks it. Write the list once in the group. Then enforce it with item assignment, not guilt.

Scan the ticket in the hallway

Partly’s AI receipt scan reads line items, quantities, tax and totals — including tickets in other languages. Assign shared staples to everyone, personal lines to one roommate, in under a minute. That is the difference vs typing a Google Sheet on the sofa.

Cadence that prevents fights

1. Whoever shops scans before unpacking.
2. Personal items are assigned immediately.
3. Settle groceries with rent on a fixed date (1st or last Sunday).
4. Use payment links (SEPA, PayPal, Revolut, Lydia, Bizum, Venmo) — not IBAN in chat.

Rotating shopper vs shared cart

Rotation is fairer than one unpaid buyer. If one person still shops more, the running Partly balance shows it. Recurring rent/utilities stay in the same group so you see the full month, not grocery drama in isolation. See roommate budget rules and how to avoid money tension.

Free vs Premium for a 3-person flat

Free: 3 groups, 5 AI scans/month, 5 payment links/month, 2 recurrences per group. A typical flatshare that scans weekly will want Premium (~€49.99/year, store prices vary) for unlimited scans. Still cheaper than becoming the household accountant.

FAQ

How do you split supermarket shops in a flatshare?

Scan the receipt, assign communal items to everyone and personal items to one person, settle on a fixed monthly date.

Should toilet paper and cleaning be shared?

Yes, unless you agreed otherwise. Put them in the communal list on day one so nobody debates €2.40 later.
