A fairer calculation starts with the actual receipt.

Let each person claim what they agreed to share

A bill action records item names, actual prices and one currency. Each participant selects the items they ordered or agreed to share. The entered price of a shared item is divided equally among its current claimants, so a person can understand why their calculated subtotal changed after someone else updated an answer.

Unclaimed rows remain a practical question for the group. A high participation count does not make their cost disappear. Review the final saved state against the receipt rather than treating an early screenshot as the settled result. A selected item is a claim in a calculation, not proof that its claimant already paid.

Review the charge basis before sharing totals

Tax and tip are entered as additive percentages of the allocated subtotal. That model is easy to explain, but it does not represent every jurisdiction’s tax rules, fixed service fee, discount or tipping convention. Check whether charges are already included in the item prices before adding another percentage.

Use a clear row for an agreed fixed charge when appropriate and avoid adding it twice through a second input. Compare the calculated total, rounding and individual allocations with the actual receipt. If the bill requires a more complex accounting treatment, use an appropriate separate process rather than hiding the difference in a convenient percentage.

Use local recognition as an editable starting point

Signed-in members can scan a printed English receipt with a bundled browser OCR engine. No external OCR account is needed. Accepted images are validated and count against a finite allowance. The review step shows candidate items and recognized text so the user can remove headers, correct prices and add missing rows.

Currency, tax and tip need explicit checking. Recognition confidence does not certify a receipt or guarantee that every row was found. The feature requires review before filling the bill builder and does not publish the bill automatically. Manual entry remains available when a photo or device does not support reliable recognition.

Keep the receipt and payment private

Temporary image retention is an explicit optional choice. A retained copy is encrypted outside public media and expires after 24 hours. The reviewed bill is separate content with its own visibility, so review its audience before sharing and manage it separately if information needs removal.

Onact calculates shares without collecting or transferring money. Use an agreed external settlement method and never post bank passwords, card details or payment tokens in an action. A response update does not reverse a transfer made elsewhere. Close the action once the final reconciliation and handover are clear.

Illustrative calculation: one shared item

Consider a teaching receipt with a personal item costing 20 units and one shared item costing 12 units. With two genuine claimants on the shared row, the personal subtotal is 20 plus 6, or 26. If the entered tax is 5 percent and tip is 10 percent, the additive calculation is 26 multiplied by 1.15, giving 29.90. Those sample amounts are not a real restaurant offer or payment record.

If a third person correctly claims the shared row, its allocation becomes 4 per claimant and the first participant’s subtotal changes to 24 before charges. Nothing about that change proves anyone transferred money. The organizer checks all rows, unclaimed costs, charge basis and rounding against the actual receipt, then the group uses its agreed outside settlement method. An OCR draft can help enter items, but it cannot make the original receipt’s accounting rules disappear.

Before you share

1. Prepare: enter the actual receipt, one currency and agreed charge basis.
2. Review: check every claimant group, missing row and displayed rounding difference.
3. Handover: settle separately and close the calculation after the final review.

Make the next request clear.
