Additional information
General
- For newly created invoice items, taxes can be selected automatically, by setting defaults:
- Set per item classification for new items added to the classification: Lists > Invoice Item Class > Select a class and Update or click New.
- Set based on item type (service or inventory): Controls > Defaults> Practice and Workstation > Invoice Item.
- If set in both, all selected taxes will be associated with the item when it is created.
- Set per item classification for new items added to the classification: Lists > Invoice Item Class > Select a class and Update or click New.
- When taxes are applied based on how an item is provided to a patient, you may want to consider using dispensing items to apply the appropriate tax when adding the item to an estimate, PVL or invoice. For example, applying a medication during appointment vs. dispensing it for home use.
- You can set up multiple tax rates to apply different taxes to specific invoice items. For example:
- Canadian practices often have a VAT/GST and PST.
- An MLSD configuration may have different tax rates by location.
Inactive taxes
- Inactive taxes do not display in any of the lists of available taxes and are not applied to invoice items on invoices.
- If you make a tax inactive, any taxed items that are currently on an estimate, Patient Visit List, or a saved invoice will retain the tax.
- To reuse an inactive tax, change the status to Active. Any previous links to invoice items are also reactivated.
- Taxes not linked to items or used in transactions can be deleted.
Multi-location single database taxes
- MLSD based taxes: taxes will be applied based on the logged in practice entering charges on the estimate, PVL, or invoice.
