Hello everyone! I have a small chain of italian restaurants and now I'm thinking of developing a custom soft for it. My comany is going to expand and I'm convinsed that website creation and software development for small business (in particular, my business) plays an important role in its future success. What is your opinion on this topic? Thanks in advance!

I can't agree with this. Years of experience are all pointing to the fact that accounting is actually one of the most influential factors in your business succeeding or failing. I recommend you do some reading on your own, starting with this page. The company that wrote this provides bookkeeping services in UK, and their clients all report a sizable increase in profits after working with them. It's almost magical, how money always disappears somewhere when your accounting department is inefficient and doesn't do it's job propely.
