Full GunBroker Automation
From Your FFL Ecommerce Platform
Auto-list your full catalog, sync orders bidirectionally, end listings the moment stock runs out, re-queue 30-day expirations automatically, and keep pricing MAP-compliant. Trinity's GunBroker integration handles the work a team of listers would — without the labor cost or the human-error risk.
The GunBroker Work You No Longer Do
Listing by hand, ending by hand, relisting by hand, price updates by hand, pulling orders out of GunBroker by hand. Trinity does all of this — correctly, continuously, without complaining.
Auto-Create from Inventory
In-stock products auto-queue for GunBroker listing with MAP-aware pricing, real-time distributor cost checks, and image fallbacks from distributor sources. You curate what gets listed; Trinity handles the assembly.
Bidirectional Order Sync
Orders placed on GunBroker flow into Trinity automatically. Shipments marked in Trinity propagate to GunBroker with tracking. Order status, payment, and FFL info stay in sync both ways.
OOS Killer Cron
Runs every 5 minutes. Ends GunBroker listings for products that have gone out of stock across your local inventory and all 19+ distributor feeds. No selling what you can't source.
30-Day Expiration Re-Queue
GunBroker doesn't auto-relist. Trinity does. When a 30-day fixed-price listing expires, the sync cron queues a fresh listing with fresh pricing, fresh cost, fresh images — not a stale copy.
MAP-Aware in 3 Places
MAP checked in calcGbPrice(), calcOfferSettings(), and buildListingFromProduct(). Product-level and manufacturer-level rules. No accidental MAP violations from cron-driven repricing.
Orphan-Listing Prevention
3x retry on DB inserts, auto-end on GunBroker if all retries fail, cleanup cron every 6 hours, and 403 responses automatically mark records as ended. Listings and database stay in lockstep.
The real GunBroker problem: scale vs. reliability
GunBroker can be the single largest channel for an online firearms business. A dealer with 2,000 active listings can easily do more volume on GunBroker than on their own website. But GunBroker also has the fewest guardrails of any marketplace — no auto-relist, no automatic inventory sync, no built-in MAP compliance, and 30-day listing expiration that demands constant attention.
The failure modes are real and expensive:
- Selling out of stock — the worst mode. A customer pays for an item you can't source. Refund, negative feedback, sometimes a GunBroker dispute. At scale this happens constantly without automation.
- Listings expiring unnoticed — every 30 days, every listing. Without an automated re-queue, a catalog of 2,000 listings needs ~65 relists a day just to stay at steady state.
- Stale pricing — distributor costs change. If your listings priced against last month's costs, you're either overpriced (no sales) or underpriced (negative margin).
- MAP violations — lose your authorization to carry a brand. Permanent. Happens easily when cron jobs update prices from cost feeds without MAP-awareness.
- Orphan listings — a listing exists on GunBroker but not in your database, or vice versa. Sales go untracked, orders get missed, reconciliation becomes a manual job.
Trinity's GunBroker integration exists because every one of these failure modes happened on the production firearms ecommerce business that Trinity was built for. Each automation is a scar — and a fix.
How the full stack fits together
GunBroker automation doesn't live in isolation. It depends on unified inventory (counter + warehouse + 19+ distributors), MAP-aware pricing, and the AI Fulfillment Picker — because when a GunBroker order comes in, Trinity needs to know instantly which distributor can ship it at the cheapest cost.
When a customer buys on GunBroker, the order syncs into Trinity. The AI Fulfillment Picker evaluates all in-stock sources. The picker routes to the cheapest distributor (or local warehouse if it's the best option). A shipping label is generated through ShipStation or EasyPost. The shipment is marked on GunBroker with tracking. FastBound records the disposition if it's a firearm. See how unified inventory works.
