Hi, By default, Amember creates invoices for all products that are sold, including 0 EUR products. I would really like my Amember site to stop creating invoices for products that are free (0 EUR) and stop registering the 'payments' (as there are none) when someone orders a free/0 EUR product. Some background why this is important: All invoices that are generated for customers by my sites, need to be included in the financial administration of my business. This includes 0 EUR invoices. However, my accountant charges 0.98 EUR for every invoice that I submit to my financial administration (it's hosted in the cloud). So effectively, I am losing money when someone 'buys' a free product and I submit the corresponding 0 EUR invoice to my online accountant. Leaving the 0 EUR invoices out of the financial administration is no option either because Dutch tax law dictates that invoices that you store in your financial administation are all numbered in a consecutive way. (e.g. invoice-2011-001, invoice-2011-002, invoice-2011-003, etc). If you would leave the 0 EUR invoices out of the financial administration, you would effectively be skipping invoicenumbers. Unfortunately, this is against the law here in the Netherlands / Holland. Right now, Amember does not treat invoices for free products any different as regular (> 0 EUR) invoices and the invoicenumber is always 'upped' with each free product being 'sold'. (e.g. to 'invoice-2011-004, etc). Hence my request above for Amember not to create an invoice for 0 EUR products and stop registering the 'payment(s)' for these free products too. Can anyone please help fix this in Amember's code? Thanks!
