A **bill** is the receipt behind a transaction. Add it to finerd and a plain line like "Amazon — \$200" turns into something you actually recognize: every item you bought, listed on its own and each with its own detailed category — instead of one rough total for the whole order. The same goes for a WizzAir charge — you see the exact ticket, route, and date, not just "Travel — \$120". finerd reads each bill, pulls out the **merchant, date, and total**, links it to the matching transaction, and breaks the purchase down **item by item** — so one payment can land in several categories instead of a single guess. The real magic is email. Connect your inbox once and finerd turns incoming receipts into bills and attaches them to your transactions on its own — nothing to scan, nothing to forward. Prefer to grab one by hand? You can always snap or upload a bill yourself. ## Why add bills * **See what a transaction actually was.** Instead of "WizzAir, Travel, \$120", open the transaction and see the exact ticket — route, date, passenger. * **Categorize down to the item.** A \$1,000 marketplace order stops being "Shopping — \$1,000" and becomes **Electronics \$700, Groceries \$200, Pet food \$100**. * **Remember purchases later.** A week on, a merchant name tells you nothing. The bill shows what you bought, so you never have to guess. ## Add bills Snap a paper receipt on the spot or upload one from your gallery. Let finerd find email receipts in your inbox and attach them automatically. Prefer not to connect your whole inbox? Forward only the bills you choose.
