Accounting Management Solution

Well, my question is about Accounting Management. I have a system already, it's work fine, but now I need to control the follow intems.

• ACCOUNTS RECEIVABLE (My Invoices)
• ACCOUNTS PAYABLE
• SETTLE ACCOUNTS
• CASH FLOW
• GENERAL LEDGER
• FIXED ASSETS
• PAYROLL

On ACCOUNTS RECEIVABLE I have all my invoice system. The rest, I need to work on it.

Is this the right way to start a new accounting module?

Does Anybody have a good source of knowledge about accounts?

Yes. Go that way, really fast. If something gets in your way ... turn.
