i use my business debit/credit card for almost everything, and send checks out for my monthly bills. with corduroy i can receive a bill, print a check for it, and then automatically download the transactions from my bank to mark that check cleared, and quickly categorize all of the new debit card transactions. at tax time, i just go through each of the categories and put the totals into the tax software.
of course it does invoicing and project management, too.
Message me if you want a copy of the template.
I've found it too unreliable and inflexible to be anything more than a supplement for my needs. They do not track all institutions, their ability to login to systems frequently breaks (for me), I find their "trends" charting really lacking, and you cannot add your own documents.
The best part is that it learns how to categorize your transactions.
It is missing invoice and payroll functionality in it's current form, but it really is so close to being the perfect accounting software for SB.
