A restaurant bill with eight items is manageable by hand. A Costco run with 60 items, a joint grocery haul with 45 line entries, or a party supply store receipt with 80 individual products — these are not. Manually assigning each item, adding up each person's totals, and calculating proportional tax is the kind of task that takes 20 minutes and produces errors.

Here's the most practical approach to splitting a long receipt without losing your mind.

Why Manual Splitting Breaks Down at Scale

Long receipts have several features that compound the difficulty of manual splitting:

Item names are abbreviated. Receipts — especially from big-box stores — use truncated product codes rather than full product names. "ORG SPINACH 5OZ" and "EVOO 33.8FL" are legible if you know what you bought; opaque if you don't.
Tax varies by item category. Grocery receipts often have different tax rates for different categories (prepared foods vs. raw groceries, for example), making exact tax allocation genuinely complex.
Quantities multiply the row count. Two of the same item appear as one line at 2x, or as two separate lines. Assignment requires interpreting this correctly.
Discounts and club prices add more lines. Sale prices, member discounts, and coupons each add rows that need to be handled correctly.

The Scan-and-Assign Approach

The most efficient method for a long receipt is to photograph it and use AI to do the heavy lifting. Jig reads the full receipt — all 60 or 80 items — and presents them as a list you can assign to people. The AI handles the item name interpretation, the quantity multiplication, and the proportional tax and discount calculation.

Your job is just to go through the list and tap whose item each line belongs to. Even for a 60-item receipt, this takes a few minutes rather than 20. And the math is correct rather than approximate.

Grouping Strategy for Faster Assignment

For very long receipts with multiple people, a grouping strategy speeds up the assignment phase:

Assign the obvious shared items first. Paper towels, dish soap, cleaning supplies, condiments everyone uses — these are shared and split equally. Mark them all as shared in one pass.
Assign clearly personal items next. Each person's specific food preferences, personal care products, items only one person uses. If you were there when the shopping happened, you'll recognize these quickly.
Handle the ambiguous items last. Items you're not sure about, or things that were partially shared. Decide on these together if needed.

When to Use Categories Instead of Individual Items

For some long receipts — particularly a large household grocery run — itemized assignment is overkill. A simpler approach: split shared household staples equally, and each person is responsible for their own specialty or personal items. "We split the kitchen basics and everyone pays for their own personal stuff" is a reasonable rule that doesn't require assigning every individual item.

Estimate the shared portion (typically the pantry staples, cleaning products, and shared food items) and the personal portion for each person. This is less precise but much faster for a household grocery run.

Handling Bulk and Duplicate Items

Costco and warehouse store receipts often have bulk items — a case of something, a multi-pack — that may be split between people. The cleanest approach is to decide ownership before shopping: "I'll take the big pasta, you take the olive oil." Then assignment is just confirmation of what was already agreed.

If you're splitting a bulk item between two people (you each get half the case), treat it as a shared item and divide its cost equally between those two people rather than including it in the group split.

Photographing Long Receipts

Long paper receipts are narrow and tall and tend to curl. A few tips for getting a good scan:

Lay it flat on a dark surface and smooth out any curling before photographing.
If it doesn't fit in one frame, photograph in overlapping sections.
Ensure all text is in focus and the lighting is even.
