Invoice Date Confusion

[gminnov]

Hello,

 

I am experiencing a problem with invoice dates on a client's account. The client has two services and wanted them invoiced together. I adjusted the dates, but only one of them invoiced. So I cancelled that invoice,and generated new invoices for both by checking the boxes on both products on his summary page and clicking on 'Invoicing Selected Items'.

 

I looked at the invoice created and it included both items, but showed the dates were for Feb-Mar, instead on Jan-Feb. So I cancelled that invoice, checked that the 'Next Date Due' on both products is correct (Jan). Then I generated the invoice again, and this time the invoice says Mar-April. How do I get this back in to alignment?

 

I would have thought that changing the 'Next Date Due' on a product would be what is required - but the invoice seems to ignore that. Which means not only does it have incorrect details in the Invoice, but possibly next month it will not invoice him because it will see his payment from this month and credit it towards Mar-April.

 

Can anyone provide some guidance on this please? I sense I am missing something.

 

Thanks.
