Handling Payments in Arrears and Advance

[mcdodd]

Hi all - need some wisdom.

 

We generally invoice for services billed by calendar month and most of our customers pay in advance. However there's a handful that negotiated payment in arrears.

 

So:

 

Customers who pay in advance:-

 

• Invoiced on the first of the month, fall due 14days later on 15th

 

Customers who pay in arrears:-

 

• Invoiced on the last day of the month, fall due 14 days later on 14th

 

I'm trying to shoehorn this into WHMCS and having trouble with the description text that appears on the invoices for customers paying in arrears. The invoices being generated always include a time period calculated for payment in advance. And if I edit the first invoice, subsequent invoices still get regenerated for payment in advance next month.

 

What's the best approach to dealing with this? Should I be expecting to get some kind of hook coded based on a custom field in the customer record or is there some easier way?

 

Thanks in advance.
