None of the Available options will work for you ?
Just seems like re-inventing the wheel to build a whole new accounting system from the ground up, when there are several options available..
After my most most recent experience with Quickbooks (last week), their horrible documentation and pathetic support, I'm questioning staying with them in the future. Guess I have to convince the accountant to switch. There where quite a few steps completely missing from the documentation for setting up Quickbooks in a Multiuser environment. Literally all my issues could have been avoided with a list containing the 5 items required to make multi-user work, but you will not find them listed in the install guide anywhere. At least they no longer require the host user to have admin privileges.. thank goodness for small favors.
