Is there any way to import data from Google Checkout into Quickbooks? (Or another accounting package)?
Yep - you can export CSV from Google and import that into Quickbooks (and presumably into other accounting packages):
You could also use the QuickBooks SDK to build an integrated application that could automatically push data into QuickBooks.
You can use the Google Checkout API to suck data out, and then QuickBooks SDK qbXML requests to push data into QuickBooks. You could automate it/schedule it so you don't have to do manual CSV imports everyday.
Open-source QuickBooks PHP framework
I found a site http://www.ktsolutionsllc.com that states to have a integration component that integrates google checkout and quickbooks. I would give that a try!
Thanks.
Please checkout InLattice (http://www.inlattice.com). InLattice supports end-to-end integration between Google Checkout and QuickBooks. You can import Invoice from QuickBooks (or manually create over web) and distribute it to your Customers. With a click of a button your customers can make a payment to your Google Checkout account. When the payment is received, you can Export the Payment back to QuickBooks. Your customers will have a separate Online access to view invoices and attachments.
Oh, btw - InLattice also supports ACH - if you are interested in lowering your Transaction fees. You can have InLattice generate NACHA file and upload it to your Bank. All for a very low monthly fee.
