In this tutorial I’ll show how to calculate service charge for specific products.

First I’ve created an account for `Service Charges`. I selected Account Type as Sales accounts.

I created an account transaction type and selected Source Account as `Service Charges`. So service charges will appear on accounts screen separately and I can report them.

We’ll need a calculation type. As we’ll calculate servicing amount dynamically I’ve selected Calculation Method as `Fixed Amount` and left amount as 0. Please be sure you’ve correctly selected `Service Charge Transaction` as Transaction type.

I’ll need an action to add Service Charges to Tickets. I created an `Update Ticket Calculation` action and selected `Service Charge` as Calculation type. I’ve also configured [:Amount] as a parameter so I can pass calculated service amount from rule.

While preparing tutorial I’ve noticed it will be useful to have a Round Amount setting for that action. That will be available with (.58)

Finally I created a rule that calculates service charge. I’ll use Ticket Total Changed rule to calculate service charge.

This expression calculates servicing amount and passes it to the action.

```auto
[=TN('{TICKET ORDER TOTAL EXP:(MG=Beverages) and (ODI=True)}') * 0.1]

```

I used `{TICKET ORDER TOTAL EXP:}` tag to get sum of selected orders and multiplied it by 0.1 to calculate %10 of it.

In this expression I applied service charge for items under Beverages Category. You can change `(MG=Beverages)` part of the expression as `(MG=Breakfast)` if you want to calculate it for Breakfast items instead of Beverages.

`(ODI=True)` part of the expression needed to exclude voided items.

We can test it to see it calculates %10 service charge for beverages but not for other items.

If you don’t have a specific product group to calculate service charges you can use product tags to enable service charge for specific items.

To do that create a new product tag from Settings \> Program Settings. I named it as Servicing.

Use Product Tag Editor to select products. Type `Yes` for items you want to enable service charge for.

Edit `Update Service Charge` rule to change service calculate expression.

I changed `(MG=Beverages)` part of the expression as `(MT.Servicing=Yes)`.

```auto
[=TN('{TICKET ORDER TOTAL EXP:(MT.Servicing=Yes) and (ODI=True)}') * 0.1]

```

You can use these expressions if you want a different calculation method.

```
  OT.<tag name> Order Tagged With
  OS.<state name> Order is in State
  OU Order User Name Equals
  MT.<tag name> Order Menu Item Custom tag Equals
  MG Order Menu Item Group Equals

```

This is how Service Charges should appear on Accounts Screen.

Accounts Screen Shows all Service Charges. In work period reports you can see amounts for reported work periods.
