Vendor credits won't show up in reconciliation because they don’t directly affect your bank account, Byron.
In QuickBooks Online (QBO), they are used to offset bills owed to a vendor, which reduces your Accounts Payable (AP) balance rather than involving an actual cash transaction.
Please note that reconciliation is specifically for transactions that impact your bank account, such as payments, deposits, or withdrawals. Vendor credits will only appear in reconciliation if they are tied to a bank transaction, such as a refund deposited into your account.
