PSS doesn’t put a limit on invoice amounts. A large payment usually fails because of a limit set by the client’s card issuer or bank. Options:
- Ask the client to call their bank to approve the charge, then try again.
- Have the client pay by US bank account (ACH), which usually allows larger amounts than cards.
- Turn on Support Partial Payments (see 6.3) so the client can split the balance across more than one payment.
