Costco receipts are hard to categorize in YNAB because one trip often covers groceries, household supplies, personal care, gifts, and a few one-off items that do not belong together.
The manual workflow is straightforward, but it takes discipline.
- Keep the receipt until the card transaction imports.
- Group each line item by budget category.
- Allocate tax across the same categories.
- Create one split transaction in YNAB.
- Add memos for anything you will want to remember later.
This gives you clean budget data, but it also turns every big Costco trip into a small accounting chore.
SNAPT shortens the workflow. Upload the receipt, review the suggested category splits, adjust anything with plain English, then sync the result to YNAB. The goal is not to remove review. The goal is to remove manual line-by-line math.
For Costco, pay special attention to groceries, household goods, personal care, pets, gifts, and business supplies. These are the categories most likely to be mixed into the same receipt.
