My goal is to import all payments from a CSV reports from my credit card processor (Authorize.net).

(We're fairly low tech, and I don't have any dev resources to integrate my merchant site to Authorize to Zoho. One of these days!)

Does anyone have a clever way of handling transactions sans invoice?

I had these notions:

1) Import the Authorize.net payments reports as "fake" invoices (I'd tweak the file headings and contents to make the records look like invoices). Then Import the Authorize.net payments reports as payments for the fake invoices I just created.

2) Create one "dummy" invoice for $1 billion, and then hit every payment against that invoice. (Maybe I'd create separate invoices for each product line or something to add a little more structure.)
