New integration helps dealers list and sell used firearms faster, with less manual work
September 8, 2026
ISELIN, NJ —Celerant Technology, a leading provider of retail software for the firearms industry, today announced a new integration with Slingit, an AI-powered platform built to help firearm dealers appraise, price and sell used firearms faster.
Used firearms represent a significant revenue and margin opportunity for FFL dealers. However, acquiring a used firearm, entering product information, preparing photos and descriptions, and listing it across online sales channels can require considerable staff time.
The new Celerant and Slingit integration is designed to dramatically simplify that process. Using Slingit, dealers can quickly identify and appraise a used firearm, capture product details and create professional, web-ready images. Through the integration, that product information can flow directly into the dealer’s Celerant back office database—eliminating duplicate data entry and creating a faster path from the gun counter to online sale.
From Celerant, dealers can publish the used firearm to their integrated eCommerce website in just a few clicks. Dealers using Celerant’s GunBroker integration can also quickly list the same firearm on GunBroker, expanding its visibility to more potential buyers.
The integrated workflow helps dealers:
- Reduce manual entry when adding used firearms to inventory
- Move firearms from acquisition to available-for-sale faster
- Create professional, web-ready product images and listings
- Publish used inventory to their Celerant eCommerce website
- Expand exposure through GunBroker
- Turn used inventory faster and maximize revenue potential
Built Specifically for the Used Firearm Market
Slingit was built specifically for the used firearm workflow, providing dealers with tools for firearm identification, pricing intelligence, appraisals and online listing preparation. Its technology helps dealers evaluate firearms at the counter, make more informed buying decisions and quickly prepare used inventory for online sale.
Together, Slingit and Celerant create a more connected used firearm workflow—from buying the gun → creating the product → adding it to inventory → publishing it online → reaching more buyers.
“Used guns can be one of the strongest profit centers in a firearm retailer’s business, but only if dealers can buy them right and get them back in front of buyers quickly. Connecting directly with Celerant takes that another major step forward. Dealers can move from appraisal and acquisition into their core retail system and online sales channels with dramatically less work—meaning less time behind a keyboard and more time buying and selling guns.”
