The right factory audit depends on what you still don’t know about your supplier. If you don’t yet know whether the supplier is real, whether it actually manufactures your product, and what it makes in-house, you need a Factory Verification Audit (FVA), which takes about one man-day on site. If you already know the supplier exists but need to know whether it can hold your quality standard through a full production run, you need a Factory Technical Audit (FTA), which takes about two man-days.
Social compliance, environmental and retailer-specific audits are a third category. Your customers usually decide whether you need those. The factory’s risk profile usually doesn’t.
A man-day is one auditor working one full day at the factory. The industry prices and schedules audits in man-days, so the term comes up throughout this guide.
The ten factors below decide which audit fits your situation. The guide also covers a few cases where the audit importers ask for first is the wrong one.
What types of factory audit can you choose from?
A factory audit is an on-site assessment of a supplier’s legitimacy, capabilities, systems or working conditions. You carry it out before you place an order or while you’re building the relationship. It is not a product inspection. An audit tells you whether a factory can make your product properly. An inspection tells you whether it did.
| Audit type | The question it answers | Typical duration | Who usually needs it |
|---|---|---|---|
| Factory Verification Audit (FVA) | Is this supplier real? Is it the manufacturer? What does it make in-house and what does it subcontract? | ~1 man-day | New suppliers, first orders, suppliers found online or at trade shows |
| Factory Technical Audit (FTA) | Can this factory control quality consistently, from incoming materials to final QC? | ~2 man-days | Technical or safety-critical products, high-value programs, long-term suppliers |
| Social compliance audit (amfori BSCI, SMETA, SA8000) | Wages, working hours, health and safety, child or forced labor | Set by the scheme | Brands supplying retailers with ethical sourcing codes |
| Environmental audit (e.g., ISO 14001-based) | Waste, emissions, chemical handling, environmental management | Set by the scope | Buyers with environmental commitments or regulated materials |
| Customized audit | Does the factory meet your checklist, retailer protocol or supplier manual? | Depends on scope | Brands with their own supplier standards |
| Follow-up audit | Were the corrective actions actually implemented? | Depends on findings | Any factory that failed an audit or had major non-conformities |
The table leaves out two points. First, official scheme audits can only be performed by accredited or scheme-approved audit firms. That covers ISO 9001 certification, amfori BSCI, SMETA and SA8000. Other auditors can check a factory against those standards, but they can’t issue the certificate or the platform report your customer may require. Second, most importers never need all six audit types. They need the right one at the right moment.
1. Is this a new supplier, or one you already buy from?
This factor decides most audit choices. With a new supplier, the biggest unknown is who they are. With an existing supplier, the biggest unknown is how consistently they work.
With a new supplier, everything you know came from the supplier: the website, the Alibaba profile, the trade-show booth, the catalog photos, and the golden sample (the approved reference sample that production is supposed to match). None of it proves the company owns the building, runs the machines, or has made your product category before.
An FVA closes that gap. The auditor checks the business license against the physical address and walks the production floor. They confirm which processes run in-house and record what the factory is actually producing that day. You get evidence instead of claims, and you get it before your deposit leaves your account.
With an existing supplier, you already know they exist. The risk shifts to quality fade: the gradual, often deliberate decline in materials or workmanship after the first few orders go well. Quality fade is a process problem, and an FTA is the audit that examines process.
Rule of thumb: New supplier → FVA before the deposit. Existing supplier you’re scaling → FTA. Existing supplier that changed ownership, moved buildings or added a new production line → treat it as new.
2. Do you know who actually makes your product?
If you’re buying through a trading company that presents itself as a factory, every quality promise you receive comes from someone who doesn’t control the production line.
Trading companies aren’t a problem by default. Many handle communication, consolidation and paperwork well, and some small-order buyers are better off with one. The problem is not knowing which you’re dealing with. If your “factory” is really a sales office, the materials, the schedule and the rework decisions all sit with a manufacturer you’ve never met.
Subcontracting creates the same problem one step further down. A furniture supplier may cut and assemble in-house but send frames out for powder coating. An apparel supplier may sew in-house and outsource printing. The subcontracted step is often where the defect you’ll argue about later comes from.
An FVA maps all of this. It establishes the relationship between the trading company and the manufacturer, which production stages run in-house, and which are subcontracted. If your critical process turns out to be subcontracted, you have three options: audit the subcontractor too, require the process to move in-house, or change suppliers.
3. How much is at stake if this supplier fails?
Audit depth should scale with the cost of choosing the wrong supplier. That cost is almost always bigger than the order value.
Start with the audit cost. At QCADVISOR’s standard rate of USD 280 per man-day, an FVA in mainland China costs about $280 and an FTA about $560. On a $15,000 trial order, the FVA is under 2% of order value. On a $250,000 annual program, an FTA is about 0.2%.
Then add what a bad supplier actually costs you. You may lose a deposit you can’t recover. You pay for a reorder from someone else. You can miss the selling season while that reorder is produced. On Amazon, the returns push your Order Defect Rate toward the 1% ceiling Amazon enforces.
Product risk counts as much as order size. If a defect can injure someone, as with children’s products, electrical appliances or anything load-bearing, lean toward an FTA even on a small order. For those products, the factory’s incoming material checks and final testing records matter more than its business license.
4. How complex is your product?
The more your product depends on tolerances, material specifications and process control, the less a verification audit can tell you. For these products, the risk sits in the factory’s quality system, and an FVA doesn’t examine that system in depth.
For simple products, an FVA plus product inspections on each order usually covers the risk. Printed tote bags, basic promotional items and packaging fall in this group. Their failures are visible, such as the wrong color, a bad print or a short count, and an inspector catches them on the finished goods.
For technical products, the failures are hidden. Mechanical parts, small appliances, furniture with hardware and load requirements, and eyewear hinges all depend on production steps that a finished-goods inspection can’t see.
In practice, the difference looks like this. An FVA confirms the factory owns the CNC machines. An FTA asks whether anyone checks the first part off each machine against the drawing, whether that check is recorded, and whether the caliper used for it has been calibrated. The FTA reviews incoming material checks, in-process inspection, final QC, equipment maintenance and operator training. Those controls decide whether part 5,000 matches part 1.
5. Who are you selling to, and what do they require?
Social, environmental and security audit requirements usually come from your customer rather than your own risk assessment. Read your customer’s supplier requirements before you book anything.
Large retailers and many brands publish supplier codes of conduct. Some require a specific audit scheme, such as amfori BSCI, SMETA (the Sedex audit methodology), SA8000 or their own protocol. Some also require the report to be uploaded to a particular platform. Find out which scheme your customer requires, which report format, and how recent the audit must be.
Then ask the factory what audit reports it already holds. Many factories exporting to Europe or the US already have a recent BSCI or SMETA report. Ask for it, and check three things: the audit date, the address, and whether the audited site is the site making your goods. An existing report can save you commissioning a new audit.
Keep the difference between an official scheme audit and an audit based on a scheme clear. If your customer needs an official report, only an approved audit firm can produce it. A customized audit built on the same checklist serves a different purpose. It tells you whether a factory is likely to pass before you commit, or it monitors the factory between official audits. The same approach applies to retailer quality and labeling protocols, which can be written into a customized audit scope.
Not sure which audit fits? Send us the product, the order size and what you already know about the supplier, and we’ll recommend a scope before you pay for anything. Our auditors travel on their own, never in factory-arranged transport, and they never tell the factory who the buyer is unless you authorize it.
6. Can the factory handle your volume and your deadline?
Suppliers can easily inflate their capacity figures, and you usually discover the gap late: your ship date slips, and the factory asks for “two more weeks.”
A supplier’s declared capacity is a sales figure. It often assumes every line running full shifts with no other orders booked. What matters is how many units the factory can produce for you, alongside its other customers, by your date.
An audit checks capacity on site. The auditor observes the production lines, counts operators and running machines, and times how many pieces come off the line in a set period. The report compares the result with what the supplier declared, in a side-by-side table of declared versus observed capacity. The same visit maps which stages run in-house, because a subcontracted step adds another factory’s schedule to your lead time.
If your order is large relative to the factory’s size, include capacity verification in whichever audit you choose. The same applies if your deadline falls in a peak period such as the months before Chinese New Year.
7. What has gone wrong with this supplier before?
Your quality history shows where the audit should focus. If you ignore it, you pay to examine areas that were never the problem.
If the same defect keeps appearing in inspection reports, the inspection is doing its job: it finds the defect. It doesn’t tell you why the factory keeps producing that defect. Inspection catches defects. It doesn’t prevent them. An FTA, or a customized audit aimed at one specific process, looks upstream for the cause. Typical causes include unchecked incoming materials, a missing in-process checkpoint, or an untrained operator on a new line.
Give the auditor your history: past inspection reports, customer complaints, return reasons and defect photos. A well-built audit scope puts those failure points at the top of the checklist, instead of auditing your supplier as if you had no history with it.
If this supplier has already failed an audit, the next step is a follow-up audit once the factory has implemented its corrective actions. A new general audit would start from zero and waste the work already done.
8. What’s your budget, and when do you need the answer?
An audit is only useful if the report arrives before the decision it’s meant to inform. Schedule it before you pay the deposit or sign the contract.
| Mainland China | Taiwan & South Korea | Other covered countries | |
|---|---|---|---|
| Rate per man-day | USD 280, travel included | USD 380 | From USD 280 |
| Travel costs | None | May apply | May apply for remote factories |
| FVA (~1 man-day) | ~$280 | ~$380 + travel | From $280 + travel |
| FTA (~2 man-days) | ~$560 | ~$760 + travel | From $560 + travel |
On timing, book 2–3 days ahead in China and 4–5 days ahead elsewhere. Urgent requests can often be accommodated, and weekend or holiday audits cost the same as weekday audits. The report usually arrives the same day. For remote factories or audits with many findings, it arrives the next morning before noon.
If your budget covers only one audit, choose the one that answers your biggest unknown from Factor 1. An audit of the wrong type saves no money, because it doesn’t answer the question you need answered.
9. Where is the factory located?
Location changes the cost, lead time and risk of the audit. Confirm coverage and travel costs before you settle on a scope.
In mainland China, travel is included in the man-day rate. Elsewhere, travel costs may apply for remote factories. QCADVISOR audits factories across China, Vietnam, India, Taiwan, South Korea, Malaysia, Indonesia, Cambodia, Bangladesh, Myanmar, Pakistan and Sri Lanka. Coverage also includes Turkey, Morocco, Portugal, Bulgaria, Greece, France and Peru.
In a common setup, the supplier’s sales office is in one city and the factory is somewhere else, for example a Hong Kong or Shanghai office quoting for a plant in another province. The audit takes place at the factory, not the office, so make sure the address you book is where your goods are made. If the supplier can’t or won’t give you a production address, that refusal is a finding in itself.
Newer sourcing locations often involve suppliers with shorter export track records and less documentation. That makes a verification audit more valuable there.
10. What will you do with the report?
Each type of decision needs different evidence. Choose the audit that produces the evidence your decision requires.
Go/no-go on a new supplier: choose an FVA. You need legitimacy, the trading-company question answered, the in-house versus subcontracted map, the capacity comparison, and an overall result.
Developing a supplier for a long-term program: choose an FTA. You need findings organized by section (production, quality control, documentation) and a clear list of non-conformities. The factory then writes its own Corrective Action Plan (CAP), which lists how each non-conformity will be fixed and by when. A follow-up audit verifies that the fixes were made. The auditor reports and verifies but doesn’t write the plan for the factory, which keeps the verification independent.
A compliance record for your customer: commission an official scheme audit from an approved firm, or obtain a recent existing report from the factory.
Which audit fits your situation? A quick decision table
| Your situation | Recommended audit |
|---|---|
| First order with a supplier you found online or at a trade show | FVA |
| You suspect the “factory” is a trading company | FVA |
| Technical or safety-critical product, moving to repeat orders | FTA |
| Existing supplier with recurring defects | FTA or customized audit, then follow-up audit |
| Large order relative to factory size, or a peak-season deadline | FVA with capacity focus (FTA if the product is technical) |
| Supplier changed ownership, location or production line | Treat it as new: FVA, plus FTA if the product is technical |
| Your customer requires BSCI, SMETA or SA8000 | Official scheme audit from an approved firm, or the factory’s existing recent report |
| You have your own supplier manual or retailer protocol | Customized audit |
| Factory failed a previous audit | Follow-up audit after the CAP is implemented |
What can’t a factory audit tell you?
A factory audit shows a supplier as it was on one day. Knowing its limits keeps you from relying on it for things it was never designed to prove.
It doesn’t check your goods. An audit passed in March tells you nothing about the shipment packed in June. Pair audits with product inspections on each order. A pre-production inspection (PPI, also called PPQ) checks materials before production starts. A during-production inspection (DPI or DUPRO) checks goods at 20–50% completion. A pre-shipment inspection (PSI) checks goods once at least 80% of the order is finished and packed.
It’s announced in advance. Factories know the auditor is coming, and some clean up for the visit. Experienced auditors focus on what a factory can’t stage overnight. They check whether calibration labels are current, whether QC records match the lots on the floor, and whether work-in-progress matches the order book.
It’s not a certificate. A quality audit doesn’t make a factory BSCI-compliant or ISO-certified in your customer’s eyes.
The objection that “the best inspector is yourself.” You’ll hear this in every importer forum, and it’s partly right, because nobody cares about your product more than you do. If you speak the language, know the product and can spend three days travelling, visit the factory. Be aware, though, that a buyer the factory collects at the airport, drives around and takes to lunch sees the tour the factory planned. An auditor who arrives independently and doesn’t reveal who the buyer is sees more of an ordinary working day. Whoever does the audit, don’t let the factory choose or pay the auditor.
How QCADVISOR helps you choose and run the right audit
QCADVISOR is an independent third-party quality control agency. It was founded in 2018, is headquartered in Hong Kong, and has in-house teams in China, Vietnam and India, with long-term partners across the rest of Asia and beyond. Our factory audit services follow the choices laid out in this guide:
- Factory Verification Audit (FVA), about one man-day: legitimacy, trading company versus manufacturer, in-house versus subcontracted processes, and declared versus observed capacity. It also includes basic environmental observations such as waste handling, cleanliness and organization.
- Factory Technical Audit (FTA), about two man-days: everything in the FVA, plus a review of the quality management system. That covers incoming, in-process and final inspections, documentation, training, maintenance and calibration.
- Customized audits: built on your own checklist, a retailer protocol or your internal supplier standard.
- Follow-up audits: to verify corrective actions after non-conformities.
We also want to be clear about what we don’t do. We don’t perform official BSCI, SMETA or ISO certification audits, and we no longer run full social compliance or ISO 14001 environmental audits. When you need one of those, we refer you to specialist partners. We don’t offer sourcing either. We have no financial ties to factories or sourcing agents, so we have no reason to approve a supplier you shouldn’t use.
Our independence rules are specific. Auditors travel on their own and never accept factory-arranged transport. They don’t reveal the buyer’s identity unless you authorize it. We vet every auditor through an industry network built over 17 years, so people with integrity problems at other firms are flagged before we hire them. A confirmed case of bribery or collusion means immediate dismissal.
Each report includes a summary and overall result, findings by section, photos and videos of key areas, non-conformities, and the declared-versus-observed capacity table. Reports are delivered to your account on our booking platform, usually the same day. If a problem is traced back to an error on our side, we take responsibility and discuss fair compensation that reflects the actual loss and our share of responsibility.
To book, register on the platform, create a project for the supplier, and book the audit. You approve the quote, and our coordination team arranges the date and address with the factory. If you’re not sure which audit you need, choose “I am not sure” on the quote form and we’ll recommend a scope.
Frequently asked questions
What’s the difference between a factory audit and a product inspection?
A factory audit assesses the supplier: whether it’s legitimate, what it can produce, and how it controls quality. A product inspection checks a specific order for quantity, workmanship, function, packaging and labeling, using AQL (Acceptable Quality Limit) sampling. Audit before you commit to a supplier. Inspect every order before you release the balance payment.
Which factory audit should I do before my first order?
Do a Factory Verification Audit (FVA). It confirms the supplier is a real, operating manufacturer and shows whether you’re dealing with a trading company. It also shows which processes are in-house or subcontracted, and compares declared capacity with what the auditor observes. For technical or safety-critical products, add a Factory Technical Audit before you scale up.
How long does a factory audit take?
A Factory Verification Audit usually takes one man-day. A Factory Technical Audit usually takes two man-days, because it reviews the quality management system in depth. The length of a customized audit depends on your checklist and the factory’s size. At QCADVISOR, the report normally arrives the same day, or the next morning for remote sites.
How much does a factory audit cost?
At QCADVISOR, factory audits start at USD 280 per man-day, and travel is included in mainland China. A typical FVA in China costs about $280, and an FTA about $560. Taiwan and South Korea are USD 380 per man-day. Outside China, travel costs may apply for remote factories.
Can a factory audit be unannounced?
Some audit firms offer unannounced audits, but QCADVISOR does not. We schedule audits with the factory’s agreement so the right managers, records and production areas are available. We manage the risk of staging on site instead: auditors compare records with what’s on the floor, check calibration dates, and review current work-in-progress.
Is a factory audit the same as a BSCI or SMETA audit?
No. BSCI and SMETA are social compliance audit schemes, and only scheme-approved firms can produce official reports. A quality-focused factory audit examines legitimacy, capacity and quality systems. If your customer requires a BSCI or SMETA report, ask the factory for a recent existing one before you commission a new audit.
How often should I audit my suppliers?
Audit every new supplier before the first order. Audit existing suppliers at least once a year. Audit sooner if management or production changes, if quality issues appear, or if you’re placing a high-value or high-volume order. Between audits, product inspections on each order tell you what is actually shipping.
What happens if the factory fails the audit?
You receive a report listing every non-conformity, with photos and notes. The factory then prepares its own Corrective Action Plan. Once the factory says the fixes are in place, a follow-up audit checks whether they actually are. A failed audit doesn’t have to end the relationship, but a factory that won’t fix the findings usually should lose your business.
Conclusion
Choose the audit based on what you don’t know yet. If you don’t know who the supplier really is, book an FVA. If you don’t know whether the supplier can hold quality through production, book an FTA. If you don’t know whether it meets your customer’s code of conduct, ask your customer which scheme applies, then ask the factory for its existing reports.
Once you have a supplier shortlisted and a deposit ready to send, book the audit before you pay. Send us the product, order size and factory location, and we’ll quote the right scope before you commit to anything.
