How did you do this? I am not seeing any way to add a custom unit. I only see the list of measurements like Acre, ft, ml, etc. I want to be able to bill in fractions of an hour. For me, .25, .50, .75 is good enough, but I would like it to appear as HRS or HR, not by the foot or yard or mile, etc

On the POS App you would click "Create Unit" - or on the Web Dashboard you just start typing in the Unit Field - or in Invoices you would click the Customize button there and type in your custom unit.

I can offer a second source on this. I was able to create an Hour time unit fairly easily as well.

In the Web Dashboard Select "Items", then on the left pick the "Units" sub item.

That'll give you the "Add a Unit" button in the upper right.

Once you click that just type what you want your Unit to be called into the "Select Unit" Field. I opted for "Hour". That will give you an option to Create "unit". Then just pick .00 for the precision type and you're good.

I try adding hours to invoice (using the web interface) and get an error message. 

"We're sorry but something went wrong."

How to make the units on an invoice be hours?  (like, 1.75 hours).

Thank you

Hey @Art-M!

Thanks for posting in the Seller Community.

Did you select customize under quantity? 

Let me know! 👀
