I have a need to be able to add the number of items on a QB invoices and enter that number of items in a custom field on the invoice.
This is possible with a little customization - we support custom fields from QB or you can build your own table to store this information inside Method.
I need to alphabatize the items on an invoice before it prints out.
This would require customization through the Report Designer, you should be able to re-order/re-sort your invoice line items.
As for an estimate on the worky ou may want to speak with a consultant o n staff since the customization may need to factor in other criteria.
