  1. Incomplete Invoices Missing details like purchase orders or tax IDs cause confusion and delays.

  2. Delayed Sending The longer you wait to send invoices, the longer clients take to pay.

  3. Limited Payment Options Clients expect flexibility — offering ACH, credit card, or online payments speeds up collections.

  5. Client Disputes Errors or unclear terms lead to disputes that stall payments.

  6. Poor Credit Policies Not screening clients increases the risk of non‑payment.
