# Billing Calculator ## Billing Calculator Service APIs to generate three distinct types of bills for MuktaSoft - wage, purchase and supervision. The API specs here enable the calculation of bill amounts. The \_estimate API performs the same calculation as \_calculate but returns only temporary results. \_calculate computes amounts for a bill, stores metadata about the bill and calls the expense service to create a bill. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
