Re: Commerce ID

[root <ro...@ma...>]

I'm not the biggest advocate of adding new fields to things for fun, but perhaps the easiest thing to do to accomodate this need as well as many other unforseen needs is to add for each invoice a few 'custom' fields that can be customized by the end user on his/her templates. i.e. custom1, custom2... then in this case you put on your templates Commerce ID: <%custom_1%> ...etc. 
This would meet this need and others we haven't even thought up yet.
But thats just my two cents ;)
