# What is causing the quantity manipulation to not save when technicians try to change the quantity of a material on sold estimates in ServiceTitan Mobile?

## Problem

Account configuration is required for technicians to change the quantities of materials on Sold estimates in ServiceTitan Mobile. Otherwise, any changes they make will revert to the original quantities.

## Solution

If changes made by a technician to the quantity of a material on a sold estimate revert back, it may indicate that your account is not configured to allow technicians to edit sold estimates. Please contact your Customer Success Manager (CSM) or [Technical Support](/construction/docs/contact-servicetitan-technical-support) to enable this feature for your technicians.

A sales tech sells an estimate. -or- A service, maintenance, or install tech sells an estimate. -or- A CSR sells an estimate over the phone. Let's say the estimate total is below the sold threshold (the customer wants to schedule the work, but hasn't fully decided).
