Examples
Parts on the bench debit inventory
You run Fern & Spoke Bike Shop. On October 9 you receive a $428 shipment of tubes and chains from Ridgeway Cycle Parts; the goods you received are the benefit. Enter a bill dated October 9: debit Inventory $428, credit accounts payable $428. Checking does not move; in QuickBooks Online or Xero this is a Bill coded to Inventory. Credit inventory instead and the parts on the bench disappear from the balance sheet.
Paying last month's bill debits AP
You run Draftline HVAC. On November 18 you ACH $1,260 to Copperline Metals for a bill you entered in October; the payment is not a new cost. In QuickBooks Online use Pay bills (in Xero, a payment on the bill): debit accounts payable $1,260, credit Checking $1,260. That debit reduces what you owe; it does not add another $1,260 to Materials. If the bank feed looks like a new expense, match it to the open bill instead of coding it again.
Why it matters
A debit is the left-side posting: it adds to an asset or expense, or it reduces a liability, net worth, or revenue. You post one on almost every bill, payment, deposit, and journal. Flip the side and cash, what you owe, and that month's profit no longer match the source documents; a credit is the opposite posting, not a better one. Do not mix it up with a debit memorandum (the paper that authorizes a debit) or debit service (paying matured loan interest and principal); read the account type, not the word on a bank card.
