One Inventory System for the
Counter, Warehouse, and 19+ Distributors

Why traditional inventory systems break for FFL dealers

A retail inventory system built for general goods has one source of truth: what's in your warehouse. A gun shop has at least four: what's at the counter, what's in your warehouse with FastBound-tracked serials, what's at every distributor you can dropship from, and what's on order.

Listing only products you physically own can limit the size of your online catalog. Trinity provides a shared catalog of 435K+ catalog UPCs, while availability depends on the distributors connected through your accounts.

Trinity combines local stock with availability from distributors connected through your accounts. UPC matching across 19+ distributor feeds creates one product entry per UPC, with availability shown across connected sources. The fulfillment picker applies your rules and shipping costs, then sorts in stock sources by cost. You decide what to carry and place purchase orders with a click.

The MAP problem and how Trinity solves it

Manufacturers (Glock, Sig, Smith & Wesson, Ruger, EOTech, etc.) enforce MAP — Minimum Advertised Price. Sell below MAP and you can lose your authorization to carry the brand. The risk is real and the consequences are permanent.

Trinity enforces MAP through two mechanisms. Product-level locks (map_locked=1) protect a specific UPC from any cron-driven price update — the price stays where you set it, regardless of what distributor cost feeds suggest. Manufacturer-level enforcement (enforce_map=1) applies a MAP rule to every product from a brand by name matching. The price is checked in three places before it goes live: when computing GunBroker pricing, when computing offer settings, and when building any new listing.

And when a manufacturer publishes a new MAP for a product Trinity doesn't yet have in the catalog (a frequent occurrence with new releases), the policy goes into eotech_map_pending or equivalent — so the moment the product appears in a distributor feed, its MAP is already enforced.

Frequent automatic cost updates

Distributor costs change. Trinity refreshes distributor feeds every 10 to 15 minutes and updates GunBroker prices and quantities every 15 minutes, helping marketplace listings stay aligned with current catalog information.

What an Inventory System for Firearms Should Cover

Gun shop inventory software has to account for more than the quantity on a shelf. An inventory system for firearms should connect counter and online sales, capture serials when firearms are received, track incoming purchase orders, and show distributor availability without treating every source as stock owned by the store.

• Shared inventory: Counter and online sales use the same store inventory.
• Distributor context: Availability comes only from distributors connected through the dealer's approved accounts.
• Receiving controls: Staff can receive against purchase order lines and capture firearm serials at receipt.
• Sourcing review: A fulfillment picker can apply dealer rules, put in-stock sources first, and sort them by cost after shipping.

Trinity firearms inventory management software combines store inventory with 22 distributor connectors and a shared catalog of 435K+ catalog UPCs. Each dealer uses the distributors its accounts allow, typically 3 to 8. Distributor stock feeds update every 10 to 15 minutes. The fulfillment picker compares connected sources under the dealer's rules, then the dealer reviews the result and places purchase orders with a click. FastBound integration is available, and the Trinity Bound Book add-on can record acquisitions and dispositions from the store's own data. The dealer remains responsible for recordkeeping and compliance.

Frequently Asked Questions

How does Trinity unify counter and distributor inventory?

Trinity matches every product across your local stock and 19+ distributor feeds by UPC. A product page shows your in-house stock, plus what each distributor has and at what cost. When the AI Fulfillment Picker chooses where to ship from, it sees all of it in one place. When you sell at the counter, online stock drops in the same second.

Does Trinity handle MAP (Minimum Advertised Price)?

Yes — two ways. Set map_locked=1 on individual products to lock pricing at the UPC level, or set enforce_map=1 on a manufacturer to apply MAP to every product from that brand. Cron jobs can never overwrite a MAP-locked price. We even maintain a pending-MAP table for manufacturer policies that arrive before the products do.

What happens when a distributor changes their stock or price?

Trinity polls distributor API and FTP feeds every 10 to 15 minutes. Website prices update every 15 minutes, the fulfillment picker uses updated source information, and out of stock GunBroker listings end within 5 minutes.

Does Trinity track firearm serial numbers?

Yes, at the serial level via the warehouse_inventory system tied to FastBound. Every firearm acquisition records the serial; every disposition (sale, transfer-out) ties to it. You can see the full chain of custody for any serial number, end to end, from acquisition to customer.

Can Trinity reorder automatically when stock runs low?

For each item, Trinity applies your rules across connected distributors, sorts in stock sources first, and compares cost after your rules and shipping. You review the result and place the purchase order with a click.

How often does Trinity update distributor inventory?

Distributor stock feeds update every 10 to 15 minutes. Website prices update every 15 minutes. Each dealer sees availability from the distributors connected through its approved accounts.

Can Trinity capture firearm serial numbers during receiving?

Yes. Staff can receive inventory against purchase order lines and capture firearm serials at receipt. Trinity also offers a Bound Book add-on and integrates with FastBound. The dealer remains responsible for reviewing records and meeting its compliance obligations.
