Seafood inventory management: a practical guide for crab houses
How crab houses and seafood markets move from clipboards, whiteboards, and spreadsheets to automated seafood inventory management — with real-time oversold alerts and daily steaming plans that actually match what walks out the door.
Why seafood inventory management is different
Seafood inventory management isn't the same problem as tracking dry goods. Crabs come in by the bushel at a market price that changes daily. Sizes shift between medium, large, jumbo, and colossal in the same delivery. Product is perishable, orders are advance-booked days ahead, and the walk-in rush on a Saturday can wipe out a size in under an hour. Generic point-of-sale systems weren't built for any of that.
The manual system (and why it breaks)
Most crab houses still run on a whiteboard behind the counter, a clipboard on the steamer, and a shared spreadsheet the manager updates when they remember. It works on a slow Tuesday. It falls apart the moment three cashiers, two phone orders, and a walk-in family all want jumbos at the same time.
The failure mode is always the same: you sell what you don't have. Someone books two dozen jumbos for 5pm pickup that you already promised at 3pm. The customer drives in, you're out, and now you're comping crabs and losing the relationship.
What good seafood inventory management looks like
A modern inventory system for a crab house should do four things:
- Track live counts by size and product, not just a single SKU.
- Reserve inventory the moment an order is taken — advance or walk-in.
- Alert the counter before you oversell, not after.
- Give the owner a daily plan for how many of each size to steam.
How CrabHub handles it
CrabHub was built specifically for this workflow. Every product carries a live sold-vs-remaining count that updates the second an order is taken on any tablet or phone. Advance orders reserve product for their pickup window, so the counter always knows what's actually available right now versus what's committed later.
Real-time oversold alerts fire the moment a size crosses its threshold — the cashier sees it before they hit confirm, and the manager gets a heads-up on their phone. No more comps, no more angry pickups.
Daily inventory planning uses the previous week's mix, today's advance orders, and the weather to suggest how many of each size to steam. The plan updates through the day as orders come in, so you stop over-steaming on slow afternoons and running out on busy ones.
How to make the switch
Transitioning from manual tracking to automated seafood inventory management is simpler than most operators expect. A typical crab house is fully live on CrabHub in under 48 hours:
- Import your product list — sizes, prices, and typical daily counts.
- Set your pickup windows and daily par levels per size.
- Get your cashiers and steamer staff on the tablet dashboard.
- Run one Saturday side-by-side with the whiteboard, then retire it.
