I completely understand your frustration. You’re right, the customer should not be able to remove these additional costs that you added for a reason. If they do not accept the additional costs they can voice their concern through the comments on the order page.
We’ve scheduled this change to be implemented for this month.
Along these same lines, it would be nice to have the system automatically enter comments describing any changes that were made to the order after the Hub clicks “accept order”.
I had a recent order where I carefully calculated the plastic volume of about 14 parts, updated the order, added additional services, got agreement from the customer through the comments, and then accepted the order. Come to find out, just prior to paying, they changed half of the parts to “quantity zero”. It took me a while to figure out exactly which parts they wanted printed and to double-check the quantity of each part against what I had calculated.
I understand and appreciate the option of the customer increasing part counts after the order is in the printing stage (prompting them for additional payment of course), but there really should be an “audit log” option to see what/when something has changed in the order.
