I totally agree on this.
Must be very easy to let the system calculate a % of tax.
I would very much like to add that we also need an auto calculate option on the discount
This would be great, but it would be even better if we could set a discount for every product-type on the company page so the calculation would be even more automated.
Right now, becouse of this issue we still need to create our quotes in our old system. We would be very happy to create our quotes within HubSpot.
