DesignerLogic is tailored with specific functions that make taking care of the books a simple process:

Financial Analysis gives you a real time status for your business. How much the total cost for all your jobs are- and how much you need to spend to complete them. How much you're charging your clients- and how much they still owe. The analysis totals this up with your bank accounts to let you know exactly how your are doing.

Just click off each invoice you want to pay with a client payment, or each PO to pay with a check.
