An AV company’s inventory is a loop, not a list. Gear leaves the warehouse in road cases on Thursday, works a conference on Friday, and lands back on the dock Sunday night - minus one wireless pack, plus somebody else’s DI box. Multiply that by overlapping jobs, dry hires to clients, and sub-rentals to cover shortfalls, and the question “what do we actually own and where is it” stops having an obvious answer. This guide covers how AV production and rental businesses keep the loop honest.

Why AV inventory drifts
- Every job is a partial inventory turn. A wedding takes a quarter of the warehouse; a conference takes half. Gear is somewhere else most weekends, which is exactly when nobody is updating records.
- Cases hide their contents. A road case is scanned, lifted, and trucked as one object - whether the fourth mic clip made it back inside is invisible until the next prep.
- Crews are mixed. Staff, freelancers, and venue hands all touch the gear. The freelancer who coiled the cables on Sunday is on someone else’s job by Tuesday.
- Dry hire breaks the loop entirely. Equipment handed to a client departs custody completely - no crew on site, no one to notice the missing projector lens cap until return day, if there is a return scan at all.
- Sub-rented and owned gear mingle. When a shortfall is covered by hiring in, the borrowed amp rides home in your truck and sits on your shelf looking like yours - until the hire company invoices for it.
The cumulative result is drift: the warehouse list and the warehouse slowly diverge, and prep for every job starts with a search party.
Per item, per kit, or bulk - deciding what gets a record
The fastest way to kill an inventory system is tracking cables individually. The decision rule: serial number or real value means per item; interchangeable and countable means bulk.
| Inventory | Track as | Notes |
|---|---|---|
| Mixers, amps, powered speakers, DJ kit | Per item, serial recorded | Serial is the theft and warranty anchor |
| Projectors, screens, displays, video kit | Per item | Lamp hours and faults belong on the record |
| Wireless mics, IEMs, comms packs | Per item or per rack kit | Pairs and frequencies matter; packs wander |
| Laptops and show machines | Per item, assigned to a person or rack | Software and show files make these high-stakes |
| Road cases and racks | Per item, with a manifest | The case label is the most-scanned label you own |
| Exhibition and trade-show kit | Per kit | Travels as a set, returns as a set or not at all |
| Cabling, adaptors, clips | Bulk stock by type and length | Count at pack-out and return; reorder on threshold |
| Tape, ties, batteries | Consumable stock | Job cost - track the spend, not the pieces |
The warehouse loop: out, back, and the gap between
The loop has three moments that matter, and only three:
- Pack-out is a checkout. Everything on the truck is checked out to the job’s holder - the crew chief, or the venue as a location - cases scanned, bulk counts noted. Thirty seconds per case at the dock door, and the register now knows what that job is carrying.
- Return is a scan-in with eyes open. Each case scanned back, condition noted, faults logged against the item with a photo. Damage recorded on Sunday night has a job attached to it; damage discovered at the next prep is just an argument.
- Monday is for the gap. The discrepancy list - checked out for the job, not checked back in - gets chased while the venue still remembers you and the freelancers still answer messages.
Everything else - mid-job swaps, gear moving between simultaneous jobs - is a transfer recorded against the item, which preserves the chain of custody instead of breaking it.
Tip: Put the QR label on the outside of every road case and a laminated manifest inside the lid. The label answers “what case is this and which job owns it”; the manifest answers “is it complete” - the two questions asked at every dock door, forever.
Renting to clients without losing the thread
Dry hire is where AV inventory goes to die, because the gear leaves with no crew attached. The fix is treating the client as a first-class custodian:
- Check the gear out to the named client with the agreed return date - the register now shows the client as holder, visible to anyone who scans the label.
- Capture condition at handover - a photo and a line of notes. Pair it with a signed equipment loan agreement for anything expensive.
- Scan in on return, condition again. Discrepancies and damage get raised that day, with the hire and the photos as evidence.
- Review overdue hires weekly. A client a week late is a phone call; a client a quarter late is a write-off.
The same mechanics cover loans to partner companies and gear sent out with freelance operators - if it left the building with a person, that person’s name is on the record.
Getting started between jobs
- Count the warehouse once, properly - a quiet week, every shelf, serials and photos for the per-item classes, counts for bulk stock.
- Label items and cases as you go - durable polyester labels, plus the manifest in every case lid.
- Set up clients and locations as assignable owners so checkouts have somewhere to point - a venue or job site is modelled as a location, a dry hire as a client.
- Run one job end-to-end - pack-out scan, return scan, Monday gap review - before rolling it out to everything.
- Make the dock door the rule: nothing crosses it, in either direction, without a scan.

AMPthilly for AV inventory
AMPthilly runs this loop without specialist hardware. Every item gets a register entry with serial, supplier, purchase price, warranty dates, photos, and documents; printable QR labels come in sizes that suit a mixer or a road case, and scanning one with a phone camera opens the record in the browser - nothing to install for freelancers or clients. Checkouts go to named people, clients, departments, or locations with due dates, so every job has a holder; the client role lets external hirers see exactly what they hold; returns capture condition; damage reports become tickets on the item’s permanent history; and the audit trail shows every job a unit has worked. The free plan - 3 users, 25 assets, no card - is enough to pilot the racks and projectors before committing, and pricing covers the rest.
FAQ
How do AV companies keep track of their inventory? Per-item records with serials for electronics, QR labels on items and cases, a checkout to the crew chief or venue at pack-out, scan-in with condition on return, and a weekly review of the gap.
How should an AV company track cables? As bulk stock by type and length, counted out and counted back. Never per item.
How do you handle equipment rented out to clients? Check it out to the named client with a return date and condition notes both ways, backed by a loan agreement for high-value hire.
What happens when gear comes back damaged from a job? Log it at the return scan with a photo - the fault gets a date and a job attached, and the item’s repair history decides repair versus retire.
Do you need barcode scanners to run AV inventory? No - a QR label and the phone camera everyone already carries do the same job without extra hardware.
The takeaway
AV inventory is a loop that drifts a little on every turn - cases hide contents, crews rotate, and dry hire removes your eyes entirely. Close the loop at the three moments that matter: pack-out, return, and the Monday gap review, with clients treated as named custodians rather than trusted abstractions. AMPthilly keeps the labels, checkouts, and damage history in one register with a free plan to start on, but the dock-door rule is what does the work: nothing crosses without a scan.
