Yes! Every A/P transaction can be linked to a sales order. So you can make A/P entries before or after you enter a sales order and the costs for the job will be automatically applied to the proper sales order. You can also enter additional costs on a job at any time after the customer is billed. And, any costs you enter before the job is billed or after, automatically update the correct G/L periods—no need to worry about skewed financials because the costs went into one month and the sales into another! With Simple Accounting, your profitability reports and G/L are always correct!
