There are two ways they can do this:
1) If Client Login is enabled under System > Settings > Company Details > Branch Details, then your Clients can log into their Client dashboard and view & pay their Invoice/Credit Request from there - they simply need to click the green ‘Pay Now’ button next to an Invoice found on the ‘Unpaid Invoices & Credit Requests’ panel.

2) They can also pay their Invoice/Credit Request without logging in via the secure payment link found on any payment request emails sent to them - this will take them to the secure Invoice payment portal.
In both cases, the Client will first be presented with a number of payment methods that they can choose from; such as Card, Bank Transfer, or Direct Debit. This page will look something like this.

Note: Which methods appear depends on the Invoice. Invoices raised using Split Payments or Automated Payouts, which includes every Invoice raised while operating as an Employment Agency, can only be paid through Stripe. Methods that are unavailable are hidden from the Client's page entirely rather than greyed out, so a Client may see fewer options than the example above without being told why.
You, as an Administrator, have the option to take payments from your Clients through Online or Offline means. Administrators do see unavailable methods, greyed out with the reason shown alongside them.

Frequently Asked Questions
Can my Client’s balance be used to mark off an Invoice?
Yes - if you have ‘Automatically mark Invoices paid’ enabled under System > Settings > Accounting > General, you can navigate to the Invoice under Accounts > Invoices > select the Invoice and select the Pay From Credit button to make a full or partial payment of the Invoice from the Client’s pre-existing credit. This is not available on Split Payments or Automated Payouts Invoices.
What happens when an Invoice is raised for a Client who does not have sufficient credit in their account to cover the total?
In this case, any credit that the Client has will be deducted from the Invoice as a partial payment, and the remainder will be reflected in the ‘Still to pay’ section of the Invoice.
In the inverse situation, where a Client has more credit on their account than the Invoice total, the remaining credit will remain on their Client balance as part of their Invoice balance.
Can I automatically charge my Clients for their Credit Requests?
