Thank you for your response. Thought, my part of my question still exists. So, if I was in the US, I should add tax to price? I have the tax rate set but choose, for some stupid reason, so include in price. Can I go in and change it, so it is added to price? 

As I previously mentioned, this is for in-person transactions.

Yes you can change it at the link I have in my previous reply. Click on the tax rate then click the drop down box below your tax name to choose add rax to item Price. 

The way you have it now you were collecting tax but getting less for each item you sold due to say a $9 item selling for $9 with63¢ in tax built in rather than a $9 item selling for $9.63. 

Okay. I believed I followed your directions though I currently do not see the difference. Should I? 

Hey @Jewels1 - You should see a difference once you run a transaction. If you're still having issues, feel free to reach back out and we can help you further.

Okay. Is there a way to do a second practice transaction?

You shouldn't need to go as far as the payment screen to see the tax on your transations.  You can do a full transaction and then just return it and if you do a "practice" transaction do it as cash.

One can keep tabs on cash Transactions through Square? 

Yes Square POS can handle cash, credit, debit and all forms of payments.  

you can see all your transactions and what type of transaction your transactions dashboard.  https://squareup.com/dashboard/sales/transactions

Is there a link here that can describe the process? Currently, cannot try it until I can get my hands on my sister's Ipad.  Thank you!
