I have QBDT2018 on two computers sharing one data file on computer A.  We currently have a license for each computer. However, we've never been able to get the two to work properly in multi-user mode.  The two users never need QB at the same time.  Due to our having Enhanced Payroll we need to upgrade QB by May of this year as QB2018 is being sunsetted.   Since we never go into QB at the same time can we purchase one license, install on two computers and share the same data file (but as stated not share simultaneously)?  Thanks
