Billing invoices - revisited

[Theo]

A few months ago I mentioned that Sedo's billing invoices (PDF's) list the amount in whatever currency the sale occured. I list & sell a lot of domains in Euro - or British pounds for that matter - and because conversion rates change (http://xe.com) daily, I am unable to keep a live track of my income as my actual payments are in US dollars. In addition, there might be a conversion issue when the tax time comes; sure, it'd be nice if the exchange rate drops but what if the euro rises substantially? Just want to make sure that the 1099 form is accurate now; instead of 4 months from now when Uncle Sam wants his taxes and Sedo gets flooded with correction requests!
