Some payments in QuickBooks may not be linked to clients for a few reasons, Nicola.
Here are the common causes below:
- If the payment amount or date differs slightly, the bank feed may fail to match it to the correct client.
- Payments categorized as "Transfer" or "Income" instead of being linked to a client’s invoice will not associate properly.
- Modifying or deleting an invoice after linking a payment can break the connection.
- Payments may be linked to the wrong client if there are clients with similar names, or they may remain unlinked if a client was accidentally deleted.
I recommend reviewing recorded payments to ensure they are entered into the correct category and not marked as "Unapplied," as this prevents them from linking to invoices.
