Quickbooks pro or otherwise aint free. I say this because I do not wish to piss money away for something I will not use.
Microsoft acces came with office, so I looked into it. They have a sample file called "northwind" that sparked my imagination.
So i dabbled with it & got more ideas.
As I said, I service apartment complexes & investors doing a wide variety of things.
Example: apartment complexes i just paint & drywall. Investors I do the entire flip.
Therefore, each apartment complex is bid out by unit/floorplan. Usually around 10 items/complex.
Now, in quickbooks that would mean a redonculous amount of inventory items. Plus, if an employee needs to do an invoice well...
But by creating a database, where said employee can log in via laptop or smartphone in the field things could be more smooth.
I dont know databases very well, but I do know that if you want a program to suit your needs you HAVE to build it, because there just isnt a 1 size fits all program for everyone.
So, from the sounds of it mysql is the most flexible & widely used program available.
Lets just use that, & toss ideas around shall we?
