WHMCS' late fee system adds late fees only one time after the due date. With this addon, you can have late fees applied every month, or every two months, or whenever you want!

Features

• Runs everyday before the regular cron job tasks - no manual setup required!
• Saves original WHMCS late fee settings and restores them when you deactivate the module. It also turns off WHMCS' late fee system on activation automatically to prevent duplicate late fees being applied to invoices.
• Follows client "Apply Late Fees" setting, so if a client is set to not have late fees applied to their invoices, this module won't apply any.
• Set frequency - set how often (in days) you want late fees to be applied to invoices
• Percentages or fixed amounts - have the addon calculate a percentage of the balance or total to apply to the invoice as a late fee, or use a fixed amount
• Minimum late fees - in case the calculated late fee is too low, you can set a minimum late fee to prevent minimal late fees
• Calculate the late fee based on the unpaid balance or the invoice total
• Send late fee email to clients - when the late fee is added, the module can send an email to the client that a late fee was added. This email template is editable!
