Good day,
I have been developing database, access, excel & etc for more than 15 years. I'd be happy to work for you on this project.
I can do the whole thing for you perfectly as needed, even with a lot of parameters and variables, this should be done as per your expectations.
For the export to Quickbooks, quickbooks accepts limited types of data like customers details, product & services I am not sure that this is what you want to expert to. In both cases, if it is something useful for you, this can be done, but it needs a 2 phase export, I can set things for you then train you for future.
If you need to keep them locally, I can do an application that is hosted somewhere, maybe locally or over the internet that allows you to manage your database wherever you are.
If you like me to do a small task, please let me know.
Awaiting your call,
Best regards,
