The city Department of Correction misspent more than $109,000 by double-paying vendors who supply jails with toilet paper, snacks and other goods for inmates to purchase, a new audit says.

Comptroller Scott Stringer’s office says it found that shoddy DOC accounting led to least 16 commissary vendors receiving 177 duplicate payments totaling $109,701 from July 2015 through late March.

The audit blames lazy Correction staff for neglecting deadlines and then taking “shortcuts” to pay bills.

DOC employees authorized payments before receiving the proper invoices and then unknowingly paid for the same merchandise again when the papers finally arrived, the comptroller said.

A DOC spokesman said the agency is recouping the $109,701 from the vendors and agreed to follow audit recommendations to tighten up its accounting after Stringer’s office spotted the errors.
