Service charge calculations

Before a service charge can be automatically applied to a check, the Toast platform has to make a variety of calculations, including the following:

  • Calculate whether the service charge is eligible to be automatically applied to a check. See Service charge eligibility. Keep in mind that you can manually apply a service charge to a check.

  • Calculate how the application of discounts affects the service charge fee. See Post-discount and pre-discount calculations.

  • For fixed percent service charges, calculate the monetary amount of the service charge fee by multiplying the check amount by the Charge Percent field of the service charge.

  • Calculate the tax on the service charge (if it is configured for taxation). See Service charge taxes.
