Matching first looks for the supplier's Item ID in your ingredients' Supplier IDs; if none matches it falls back to the ingredient name (exact, or at least 75% similar), which can pick a similarly named item. On the review card click the pencil next to the linked ingredient name, type at least two characters to search your active ingredients by name or ID, and click the right one; the card's current COGS, base weight and unit refresh and the Supplier ID on that card will be saved to the chosen ingredient so the next receipt matches correctly. If the line should not be imported at all click Dismiss.
