I've just gotten started doing business in bitcoins and I'm curious what solutions other bitcoin businesses use for bookkeeping.
As a small (micro) business I need to keep expenses infinitesimal. Is there any bookkeeping software or website that can handle btc and dynamically import exchange rate data? Anything that offers an API extensible enough to add this?
I built an accounting system in Excel for one of my University classes a few years back... certainly, the current BTC rate would be easy to grab, so I wonder how easy it would be to adapt the rest of the spreadsheet for use with BTC?
How would you want exchange rate data to be calculated? Grab the exchange rate for each transaction on the date/time it happens, or just view all transactions at current value?
