Some buyers never get to the gate.
Sometimes it is the visa. Sometimes the shortlist has four suppliers on it and the travel budget covers one trip. Sometimes the order is not big enough to justify a week away from your own business — a perfectly rational conclusion. Whatever the reason, the message arrives in almost the same words every time: I cannot come — can we do it by video?
You can. It is worth doing. And in the form most buyers accept it, it is close to worthless.
Here is how it usually goes. The supplier calls at the agreed hour, already inside the building, and walks a smooth route. The picture drops a couple of times, because the signal is poor at the far end, and comes back somewhere else. Forty minutes later you have seen a clean line, a stack of finished units, a warehouse and a man in a white coat at a bench — and you feel considerably better about a supplier you know exactly as much about as you did before.
You did not see a factory. You watched a film, shot in one take by the person with the most to gain from what was in the frame.

Why Most Video Factory Audits Are a Guided Film
A site visit is a hosted event. A video call is a hosted event where the host holds the camera, and that changes everything.
| Standing in the building | On the call as it is normally run | |
|---|---|---|
| What you can look at | Anything in your line of sight, including what nobody meant to show you | Only what is inside a frame somebody else is aiming |
| Where you can go | Stop, turn round, walk back | The route was decided before you dialled |
| What reaches you | Noise, heat, solvent, dust, the floor underfoot | A phone microphone, and whatever the building does to the signal |
| How long you get | As long as you stay | As long as they planned for |
| Who you can talk to | Anyone who walks past | Whoever is handed the phone |
None of that is dishonesty — give any of us a camera and a customer and we would show our best corner too. But the default video tour is evidence of one thing: that the supplier has access to a building that looks like a factory, which is a far smaller claim than the one you are testing.
The difference between a tour and an audit is not the camera or the connection. It is whether the rules were set by you, in advance, or by them, in the moment.
The Rules You Agree Before Anyone Picks Up a Phone
All of this goes in one friendly message, days before the call. None of it is unusual; a supplier who does this regularly has heard it all before.
| The rule | Why it is there |
|---|---|
| Live, not recorded | Anything sent in advance is a brochure — an answer to a question you did not ask |
| We don’t send the route | You will say where to go during the call. A list sent beforehand is a rehearsal schedule |
| A working day, in production hours, their local clock | Fix date and time in their time. Avoid the days around public holidays — a quiet plant is quiet for good reasons then |
| The camera is carried by someone from the workshop | Production or quality staff, not the salesperson, who cannot answer floor questions and steers past things by instinct |
| You can stop and redirect at any time | Agreed out loud beforehand, so interrupting is not rude |
| Forty to sixty minutes, one session, one connection | Long enough to get past the prepared part, short enough that nobody cuts it short |
Read the reply carefully: that message is already doing work. A supplier who agrees to all six has accepted that he will not control what you see — the first finding of the audit, collected before anyone switches a camera on.
The Walk: One Continuous Take, in This Order
Ask for one thing above all others: an unbroken walk that starts on the street outside, comes in through the gate, and carries on through the building without stopping.
Continuity matters more than resolution or lighting or anything you see, because a break in the picture is the only place where the geography can change. Everything you are trying to establish — that the yard, the workshop, the stock and the warehouse are one site, and that the site is the one on your quotation — lives in the joins rather than the frames. Where the picture stops, the audit stops.
Dropouts are also normal: a steel-framed workshop is a poor place for a mobile signal, and no supplier can promise otherwise. So the rule is not “never drop”, it is agreed in advance — if we lose you, go back to where you were standing and start again from there. Someone who resumes forty metres further along has deleted forty metres without meaning anything by it.
| Where the camera goes, in order | What that stretch is evidence of |
|---|---|
| The street outside, then in through the entrance | That the building sits where the address you checked says it does, and the gate name matches your paperwork |
| The yard and the loading area | Two-wheelers in the rack, scrap and packaging waste, tyre wear, whether anything is moving. The parts nobody tidies |
| The workshop, one slow pan from the door | Scale against the scale they described: how many workstations exist, how many have somebody at them |
| The line or cell that would build your order | Whether it is a thing or a claim. Ask them to walk it end to end |
| Work in progress and semi-finished stock | The hardest thing here to stage, and the most valuable |
| Machines close up, including the nameplates | Age, condition, whether they are warm, whether there is swarf under them. Hold steady on the one that matters most to your part |
| The warehouse and finished goods | How much is there, how long it has sat, whether it looks like their product |
| The quality bench and any test rig | Whether the instruments are in use or under dust |
Work in progress deserves its own line. Finished goods can be bought in from anywhere; half-built work cannot, because a batch part-way through only exists if that process is running in that building. When time runs short, push for this rather than the tidy row of finished units at the end.
Proving the Factory Is Live, and Is This One
This is where a video audit stops being a video tour, and it costs nothing.
| Ask for this | What it settles |
|---|---|
| A few seconds pointed out of a window or the doorway | Daylight and weather against the hour you agreed. Work out beforehand what the sky should be doing in that province. Dusk in the middle of their working afternoon means the footage is not live, or the building is not where you were told |
| A detour nobody planned | The far corner behind that column, or through that door on the left. Same principle as asking your host for small ordinary things on a site visit: familiarity with a space cannot be performed |
| One small physical action | Tap the nameplate on that machine and hold still on it. Ask the operator to turn over the part in his hands, or someone to tip a crate up. Recorded footage cannot do as it is told |
| A number you have just invented | Say one you made up thirty seconds ago and ask for it written on a scrap of card and held up. Odd, harmless, conclusive: no file recorded last month contains a number that did not exist until you said it |
Spread them out: the window early, before anyone has settled into the route, and one kept back for the far end of the call. Frame them as housekeeping rather than tests — for our file covers it — because the moment a supplier feels examined you have swapped a small piece of information for a large piece of goodwill.
What a Video Audit Cannot Tell You — Even a Good One
This is the honest part, and skipping it is how buyers talk themselves into a deposit.
| What an hour on camera looks like it proved | What it actually proved |
|---|---|
| They have the capacity for your order | That equipment exists. Capacity is output over time — plans, output records, staffing, material movements. None of it fits in a viewfinder |
| Those are their workers | That people were in the building for an hour |
| Those are their machines | That machines were on the floor. Machines are rented, borrowed and shared more often than buyers imagine |
| That stock is theirs | Finished goods belong to whoever ordered them, frequently somebody else |
| Quality control is running | A bench with instruments on it is furniture until you see records and watch somebody use them |
| The site is theirs | Occupancy is not ownership. The lease is a paperwork question |
So say it plainly. A video audit does not replace a visit. It filters. It is very good at removing suppliers who are obviously not what they claimed, and close to useless at confirming the ones who are. A clean call means nothing disqualifying was visible — useful, and not the same sentence as this supplier is verified.
It also sits in one place in a sequence. The desk work comes first and answers what no building can: check the addresses and the register before you book anything, then our company due diligence workflow. Once the order is placed, video changes jobs — from establishing who they are to watching what they make — and that is remote quality control, a different discipline with a different toolkit.
When Refusing the Camera Is Not a Red Flag
This is the part most supplier-verification advice leaves out, and leaving it out costs buyers good suppliers.
A supplier who will not film everything is not hiding a scam. Most of the reasons are ordinary, and several reflect well on him:
- Another customer’s product is on the floor. Contract manufacturers are routinely forbidden by their own contracts from filming where somebody else’s work is running. A supplier keeping that promise is showing you the promise he would keep about you.
- Regulated or controlled production. Plants working on defence, medical or certain licensed products operate under filming restrictions that are not theirs to waive, whatever they think of your request.
- Plain site rules. Cameras on the shop floor are restricted at many industrial sites for safety and insurance reasons, and the person on your call may have no authority to change that.
- Assembly operations look thin on camera. Some suppliers are not manufacturers in the sense you are picturing. Their skill is selecting and controlling component suppliers and building the finished unit themselves — a real model with real advantages: they buy components competitively instead of being stuck with whatever their own line can produce, and they are far more flexible on small batches, spec changes and delivery dates. Some of the best price-and-quality combinations we source come from exactly this kind of company. On a phone camera an assembly hall is a large room with benches in it — the least impressive thing anyone can film, and often the best commercial decision available to you. We set the three types out in factory versus trading company.
The question is never whether they will point a camera at everything. It is whether, when they cannot, they offer you another way to see the same thing.
| Refusal that reads well | Refusal that does not |
|---|---|
| “Not the bay where another customer’s product runs. Everything else, yes — and if you visit, that too” | “Company policy”, with nothing after it |
| “Filming isn’t permitted here. We’ll accept an inspector you appoint, or share the cost of a third-party audit” | A pre-recorded video offered instead |
| “Come and walk the whole plant — pick a date” | “Later, when production is running” |
| “Not that room” — specific, named, walk continues | A route that keeps drifting from what you asked for |
An assembler who says we assemble, these are our component suppliers, come and inspect the incoming parts is a supplier, often an excellent one. A trading company filming a plant it merely buys from, as though the line were its own, is a problem. The concealment is the problem, not the empty-looking room.
Two related patterns have their own articles: what it means when your contact suddenly cannot attend and the factory receives you instead, and what the distance between a city office and the plant really costs you.
Score It, Don’t Veto It — and When to Send Someone Anyway
Nobody should drop a supplier because a phone lost signal in a steel building, and we do not.
What it changes is the score and the questions. Price risk: if part of the process happens somewhere you could not be shown, somebody else’s margin and schedule are inside your price — a cost conversation rather than an accusation, the same one as negotiating factory prices without losing quality. Quality risk: every operation at an address you have not seen is outside your inspection until you write it into the plan. Then we put the supplier beside others in the same tier.
Findings are deductions, not death sentences. A supplier who filmed two-thirds of his plant, explained the third he could not, and named a date for a visit routinely beats one who filmed everything smoothly and answered nothing.
What the call does decide is whether a person still has to stand in that building:
| Send someone when | Why |
|---|---|
| It is the first order with this supplier | No track record to fall back on, and the first order sets the pattern |
| Losing the money would be a problem, not an inconvenience | The threshold is yours, not ours |
| The goods are made to your drawing or spec | On custom work the process matters more than the product — and process is what a camera shows worst |
| The lead time is long or the payments are staged | You are funding work you cannot see, for months |
| They refused a rule and offered no alternative | You have been told what the call was for |
| The desk work left a question open | Some questions are answered by buildings, some by filings; a camera answers neither |
That person does not have to be you, and usually is not: a third-party audit firm, an inspection company or an agent already in the country can stand in that building for a fraction of the trip, briefed with the one-day factory audit checklist. What you must not do is upgrade nothing looked wrong on a phone into verified and carry it into a deposit. Money-side controls are in our guide to protecting payments on machinery orders from China; the check that catches most expensive surprises — account name against contract name — has an article of its own. And if the trip does happen, the first sixty seconds at the gate are the part nobody arranged for you.
Before You Dial: The Preparation Checklist
Half of a video audit happens before the call connects.
- [ ] Run the desk checks first — Chinese company name, the 18-character unified social credit code (统一社会信用代码), the register, the addresses on a map
- [ ] Send the six rules in one message and get them agreed in writing
- [ ] Fix date and clock time in their local time, on a working day in production hours — and work out what daylight should look like then
- [ ] Ask for workshop or quality staff to carry the camera, your usual contact on the call
- [ ] Write your route out in advance — and do not send it
- [ ] Have your invented number ready before you dial
- [ ] Brief your interpreter to pass the small requests on casually; our notes on visiting a Chinese factory when you don’t speak the language cover that briefing
- [ ] Ask permission to record at your end
- [ ] Agree the dropout rule out loud: resume from the same spot, not further along
- [ ] Note the time of every break in the picture and what appeared after it
- [ ] List, before you hang up, what the call could not answer and how you will answer it instead
- [ ] Write it up the same day, into the supplier risk scorecard, not into your memory
A video call cannot verify a supplier. It can stop you flying to the wrong one, and tell you in an hour which name on the shortlist deserves the trip. Set the rules before you dial, ask for one unbroken walk, and write down honestly everything the screen could not show you.
