I'd second that request. In my case, I offer a shipping discounts on orders within a 5 day range, and about 25% of my orders turn out to be multiple auction and/or store buys, so I frequently need to merge invoices as well.

In fact, when I have a lot of invoices to handle, I sometimes have to check each one for "merge possibilities". A button would make it easier - but it would be even better if there was an option to combine invoices during invoice creation with "any matching open invoices" - that would solve the problem in it's entirety.

Also - a big THANKS to who ever posted the html+template code for the combined paypal purchase link. For some buyers, its a major convenience.

Since the start of 2003, I've processed over 200 invoices and 500+ auction lots - I simply couldn't handle it without AW2K. This is a fantastic program!!
