Accounts payable  $616,056   $918,639 
Sales commissions payable   27,592    48,263 
Accrued payroll liabilities   322,873    288,071

Other accrued expenses   192,463    356,623 
Total  $1,345,589   $1,784,961 

 

The December 31, 2020 accounts payable and other accrued expenses included $402,651 relating to a one-time warranty issue experienced on three customers’ projects. The expenses related to parts and labor to repair units that had been delivered to these customers prior to year-end. Since the issue was limited to these three projects and is not anticipated to reoccur in the future, we have made no adjustment to the ongoing 1% warranty reserve that we accrue on all sales.
