Best Software for Start Ups?

Can you answer Devoted’s question about Factoring?:

Hi! I am in the last phase of writing my business plan for a start up company and need to know which is the current best software? My payroll will be outsourced to ADP. My employees will be more than 10- less than 30. My business needs are: basic accounting Accounts Receivable/Payable and I will need a database capable of handling LARGE amounts of personal info. Basically, I am needing to store intern applications plus essays for long term whcih will be downloaded from a website submission form. I also need to be able to merchandise and handle inventory- just between 10- 30 items. I would so appreciate any input from you techie folks out there. Cost is not the most important factor- speed and reliability are. Thanks! (I am in Atlanta GA)
