How can I add an estimated display tax in the store editor?
Each photographer is able to add an estimated tax which will be displayed for all items in the store editor while the client is choosing/designing their products. This estimated tax allows for better transparency to what the final product cost will be. The estimated tax is removed once the client inputs their shipping information in the cart. During this step, the estimated tax is replaced with the calculated, final tax amount.
Adding Estimated Tax
Click Settings from the main dashboard.

Select the Store Settings tab, then click Setup.

Check-mark Display product price including tax. Input the Display tax amount and click Apply.

The Store Editor will now include the estimated tax in the editor window. The final tax will be calculated once the client inputs their shipping information in the shopping cart.
