A day with the warehouse manager

Wake to bed.

12 waypoints. 2 peak-stress hours.

5:45a

Lights on

First one in. Coffee from the pot he loaded last night on a timer, the warehouse still cold from the overnight. Pulls up tomorrow's job list and today's inbound on the laptop at the receiving desk — six installs staging, three pallets due from the supply house by ten.

6:15a

Stage walk

Walks the staging lanes before the team clocks in. Six install kits laid out by truck number, equipment tags facing out so techs can scan without flipping boxes. Catches a missing P-trap on the second-floor bath job and pulls one from rack twelve before the Installer even shows up.

6:45a

Crew huddle

Two of his warehouse hands and the Inventory Coordinator in the break room. Walks the day in two minutes — three pallets inbound, six trucks loading by seven-thirty, cycle count on the brass fittings bin after lunch. Coffee in the carafe, donuts somebody brought; doesn't make a thing of it.

7:15a

Truck loading

Stands at the bay door with the loading sheet on the tablet while install crews back in. Each truck's kit gets scanned out, signed for, and loaded under his eye — the staging discipline is the whole point.

9:00a

Inbound shipment

First pallet from the supply house arrives, two hours late but inside the window. Walks the Inventory Coordinator through the count against the PO, catches a short on the 3/4 PEX — five rolls instead of eight. Photos it, opens a vendor claim on the laptop before the driver pulls away.

10:30a

Vendor call

Calls the supply house rep about the PEX short. Doesn't yell — names the PO, names the count, sends the photo, asks for the rolls on this afternoon's run because the Tuesday installs need them. Gets the commitment, logs it in the inbound tracker.

11:30a

Variance hunt

Cycle count from yesterday flagged a two-unit variance on 24-volt transformers. Pulls the receiving log, the install pull sheets, and last week's truck restocks. Finds it — a tech pulled two for a job and the apprentice didn't scan them out. Walks it to the dispatcher to log against the right work order before lunch.

12:30p

Lunch at the desk

Sandwich and the same gas-station iced tea. Reviews tomorrow's job list against current stock — seven installs, two of them heat pumps, and the matched air handlers are sitting at three. Texts purchasing to confirm the Friday inbound is on schedule before he chews twice.

1:30p

Tomorrow's stage

Starts pulling tomorrow's staging while the warehouse is quiet. Scans each kit against the job list, lays them out by truck, tags equipment with the customer name on a printed sheet. Doesn't stage at the last minute — that's how you ship the wrong condenser.

3:00p

Cycle count

Walks the brass fittings bin with the Inventory Coordinator. Counts, recounts, reconciles in the system. One-unit variance on 1/2 inch ball valves — small, but he opens the receiving log anyway. Small variances are the only kind worth chasing; the big ones announce themselves.

4:30p

PEX rolls arrive

Supply house second run pulls into the bay at four-thirty as promised. Receiver counts them in, files the closeout against the morning claim, and tucks the rolls onto tomorrow's Tuesday install staging lane. Closes the open claim in the system.

5:30p

Lock up

Walks the floor one more time. Six installs cleared, tomorrow's seven staged and tagged, brass variance noted, PEX claim closed. Lights off, side door, alarm armed. Texts the Installer a thumbs-up that the matched air handlers will be on truck two by seven.
