Chief_Apricot, how is this coming? I've just exported the "TRANSACTION LIST" and have some input on how integration with quickbooks would/could/might work...
First, the transaction export is missing some information. I imagine most members could pay by credit card (paypal in my case) or by mailing a check. The transaction export should have some way of identifying this. I don't believe it currently does. Perhaps you could add a payment type column and if payment was made by the user, it could say "User generated Paypal transaction" versus "administrator generated payment" or something like that.
Second, as I'm sure this is true with all member lists, there are duplicate names. If an organization has 5 john smith's and 3 renew at the same time, only Smith, John would appear on the export. If the export could include a member number or email address that would make troubleshooting much, much easier if any payment problems were to arise requiring research.
I would only need this type of information in an export b/c then I can use other excel sheets or Microsoft access tables to link all the tables together and import them into quickbooks. But it's best to have member specific information to help with troubleshooting, therefore an email or member id on the transaction export is essential, along with some type of payment type column so you'll know what bank account to use when importing into quickbooks.
This may sound silly but I'd be happy to share my files with you to give you an idea how I set up my Quickbooks imports if you think that would be of help, just drop me a line!
