Sometimes after you've completed a Bulk Price Change, a client's appointment may still be displaying the old price (and therefore a discount at sale).
If this happens, no problem! Follow these steps to resolve the issue:
Editing the service or product at 'POS' to reflect the price change as you go
When you're ready to finish the sale:
1) Add the client to sale.
2) Click on the service(s) that are applying the discount.
3) In the right-side panel, de-select the original service from the 'Service' drop down.
4) Re-select the original service from the 'Service' drop down.
5) Click 'Save' to resolve the issue.
All done! The service will no longer have the discount applied.
