When you source from China without a senior engineer on the floor, you're trusting a sales relationship to deliver an engineering outcome. QESaaS is the independent quality management and on-site inspection partner for Kickstarter brands, DTC launches, and small businesses with no in-house US engineering team to put on the factory floor themselves.
China is a global manufacturing powerhouse, and small brands — Kickstarter founders, DTC launches, FBA private-label sellers — increasingly source there because the cost and capability advantage is real. The challenge is that the same factors that make China attractive (specialization, scale, supplier density) also make quality opaque when you're sitting in the US looking at WeChat photos and a sourcing agent's reassurances.
Quality without a physical presence at the factory is a guessing game. A sourcing agent translates conversations and chases timelines — that's a commercial function. A senior quality engineer on the floor evaluates whether the line can actually produce the product you specified, at the volume and consistency you committed to, against the standards a Fortune-500 supplier-quality engineer would apply — that's an engineering function. The two are not the same, and the second is what protects your brand from a recall after launch.
QESaaS is your engineering presence at the factory. I fly to your contract manufacturer (CM) in mainland China, spend one or two days on the production line, and deliver a written 15-page findings report within seven days of returning to the US — including comparable-recall context drawn from the federal CPSC / FDA / NHTSA / USDA pipelines I maintain for RecallSentry.
If you're about to ship a hardware product through a Chinese CM you haven't visited in person, this is the service that closes that gap before the tooling money commits.
$250K+ raised, 3–9 months from delivery, named CM but no factory visit yet.
Product 1 had quality issues. Product 2 needs a senior eye on the line before shipping.
One high-margin SKU where a recall would end the business.
Moving to a new factory. Want a fresh-eyes audit of the new partner before committing tooling.
QESaaS structures every China engagement around the same two pillars every senior quality engineer is trained to think in. QA prevents problems before they happen. QC catches them before they ship. You need both, applied with engineering judgment — not a checklist run by a junior.
Quality Assurance is the set of guidelines, standards, and process discipline a supplier must follow to consistently produce your product to spec. The aim is to push quality upstream so the line is built right, not inspected right at the end.
Quality Control is the inspection, testing, and verification of the actual product the factory produces. The aim is to confirm that the line is producing what was specified — and to identify defects before the carton seals.
Every QESaaS engagement covers both. A factory with strong QC and absent QA ships clean batches today but is one supplier change away from a quality cliff. A factory with strong QA and weak QC has the right intent but doesn't catch the defects. The report names which is which, with photo evidence and a remediation action list.
Most factory inspection services in China are commodity AQL checklists run by rotating local inspectors at $200–$650/day. The next tier up is a Big-4 brand-name audit for $1,500–$2,500/day — also local staff, also templated. QESaaS sits in an empty band that competitors structurally cannot fill: one named senior US engineer flying in, federal recall-pattern data, paid in USD by the founder. Here is the full list.
We don't source factories. We don't take factory commissions. We can't be compromised by your CM because we don't know your CM until you tell us. Paid by you, in USD, into a US bank account — the only commercial relationship in the engagement is between QESaaS and you.
Same name on the audit report, the published byline, and the LinkedIn profile. Not "an auditor." Not "whoever was available that day." Every QESaaS audit is performed and written by Mark Mayeux personally.
Every audit cross-references findings against 20+ years of US federal recall data — CPSC, FDA, NHTSA, USDA — refreshed daily through the RecallSentry pipelines. The failure modes observed on your line are named alongside the past recalls in your product category that came from the same gap. No surveyed competitor offers an equivalent.
The standards a Fortune-500 supplier-quality engineer applies — ISO 9001, ANSI Z1.4 sampling, IPC-A-610, IEC 60068 — sized for a Kickstarter brand's budget. Twenty-plus years across medical devices, aerospace, and consumer goods.
The single biggest sourcing risk is wiring $50,000+ in tooling money to an entity that turns out to be a sales office, not a factory. The pre-audit document review (business license, customs registration, address GPS, tax registration) catches Tier-4 traders posing as factories before the flight is booked.
Local inspectors run AQL pass/fail at the end of the line. Senior quality engineers measure process capability mid-line — stated capacity vs observed throughput, claimed sampling plan vs actual sampling, documented defect rate vs sampled defect rate. The delta is where field returns come from.
You're not just inheriting your CM. You're inheriting their PCBA assembler, their cell-pack supplier, their injection-molding shop, their packaging vendor. The two-day audit maps one sub-tier visit within one-hour drive — because the inheritance is where most surprise recalls come from.
QIMA, AQF, and the rest are calibrated for importers running pre-shipment inspections every shipment, every month, for years. You're producing 5,000 units once. The right product isn't five sessions with a junior inspector — it's one senior engineer for one or two days who reads the line correctly the first time.
An update to your backers that reads "A senior US quality engineer was on the factory floor last week and reviewed the production run" lands differently than "Our sourcing partner says everything looks good." Named engineer + photo evidence + verbatim findings = the gold-standard pre-shipment trust signal.
The engagement letter is on QESaaS LLC paper, paid in USD into a US bank account. No Chinese entity in your payment chain. The on-site work operates under the M-visa fact pattern for short-term commercial visits. Procurement-side trust signal for sophisticated buyers.
A US-based contract manufacturer can be evaluated through a half-day phone call with the plant manager. A Chinese CM, sourced through an agent or an Alibaba intro, cannot.
The biggest single risk in China sourcing is committing tooling capital to an entity that turns out to be a sales / trading company rather than an actual factory. QESaaS classifies every CM into Tier 1 OEM, Tier 2 mid-size, Tier 3 small, or Tier 4 trader-posing-as-factory before tooling commits — based on business-license verification, address-match GPS check, production-floor walk-through, and worker-headcount-versus-capacity arithmetic.
A sourcing agent's incentive is to close the deal. A senior quality engineer's incentive is to tell you whether the factory can actually deliver. Independence matters here — QESaaS is paid by you, the US client, in USD into a US bank account. We are not paid commissions by the factory and have no incentive to soften findings.
The showroom sample is hand-finished by the factory's best operator on the factory's best day. The production output is what comes off the line at 1am on day 21 of a 30-day run. Quality Management catches the gap between the two — the process-capability drift that produces field returns at scale even when the samples were perfect.
The cost of catching a defect at pre-production-run is dollars per unit. The cost of catching the same defect at warehouse arrival is dozens of dollars per unit plus rework. The cost of catching it at the customer is your brand, your reviews, and potentially a recall. QESaaS pre-launch audits are scheduled to land before the production run, not after.
Four to six weeks from kickoff to delivered PDF. Visa, flight, and CM coordination handled. Travel reimbursed at cost against itemized receipts.
A sourcing agent, the CM, and a commodity inspection service each have a role — but none of them is the same role as an independent senior quality engineer reporting to you in writing.
No agent-factory commission alignment. No marketing-flavored "qualified supplier" recommendations. The findings are what they are — the engineer works for you, paid by you, in USD on a fixed fee.
20+ years of US-side product quality engineering across medical devices, aerospace, and consumer goods — applied to the factory floor in Shanghai, Guangzhou, or Ningbo. ISO auditor credentials. The same standards a Fortune-500 supplier-quality engineer would apply, sized for a Kickstarter brand's budget.
Commodity inspection services run AQL-pass checklists by junior inspectors for a few hundred dollars a day. QESaaS is a different product: senior judgment applied to your specific product category, with recall-pattern context from 20+ years of US federal recall data tied to the failure modes observed on your line.
A consumer-product recall in the US averages low six figures in direct cost — refunds, logistics, rework, legal — before brand-damage cost is added. A QESaaS audit is $3,500–$5,500 plus travel. The math is not subtle.
One person owns every engagement. No fictional staff. No rotating contractors. The name on the report is the name who was on the floor.
20+ year senior QA engineer. ISO 9001 / 13485 lead auditor (CNAS scheme accepted). Direct supplier-quality audit experience inside Chinese contract manufacturers — Shanghai, Guangzhou, and Ningbo, among others. Past Director of Quality at a US/China medical-device sourcing operation. Built the entire quality department at a medical-equipment startup from scratch, later acquired.
Also the builder behind RecallSentry™ — a published iOS and Android app monitoring federal recall feeds across CPSC, FDA, USDA, and NHTSA. The same daily-running data pipelines provide the recall-pattern context cited in every audit report. The observed failure modes on your line are named alongside the specific past recalls in your product category that came from the same gap.
Two standard tiers, one number each, plus travel reimbursed against receipts. No hourly billing. No markup on flights or hotels. Custom engagements (multi-CM comparative, post-incident root-cause) on quote.
Multi-CM comparative audits (2–3 CMs same region, single trip) and post-incident root-cause audits available on custom quote. Travel typically runs $2,500–$5,500 from US west coast to mainland China; quoted on the scoping call.
Knowing the limits is what makes the price quotable and the deliverable clean.
If any of the items below are what you actually need, this is not the right service. We'll tell you so on the scoping call before invoicing.
The questions that come up most often.
Those are checklist audits run by a junior inspector — typically a one-day social-compliance pass at $1,500–$3,000. They verify the boxes get ticked. This service is a senior QA engineer running a process-capability and supplier-quality audit, with named recall-pattern context applied to your specific product category. Different product, different price, different decision.
Those firms charge $200–$650/day for a local Chinese inspector running a templated AQL checklist — and many publicly market "we rotate inspectors every 3 months" because long-term factory familiarity is a known bribery risk. QESaaS sends one named US senior engineer ($3,500/day + travel) once. The engineer doesn't rotate because he flies in from the US, doesn't know your CM, isn't paid by anyone whose interests align with the factory. The deliverable is also different — process-capability read and recall-pattern data are not in a commodity inspection report.
Four to six weeks. Two weeks for invitation letter + visa (or zero if entering under the current US passport visa-free 30-day program), two weeks for flight and CM coordination, one to two days on-site, then seven days for the written report.
Best path: your existing Chinese sourcing agent or trading partner — they typically issue invitation letters as a routine service. Workable but flagged: the CM being audited (conflict of interest is real but doesn't invalidate the letter). Last resort: a paid third-party "DAU" service. We work through this on the scoping call.
Yes. Mutual NDA before any product documents change hands. One-page template available; your template is fine too. Note that for proprietary designs, an NNN agreement (Non-Disclosure / Non-Use / Non-Circumvention) in Chinese with PRC jurisdiction is materially stronger than an English NDA — we flag this in the engagement letter.
This service is mainland-China-specific because the visa fact pattern, the on-site checklist, and the IP-protection considerations all key to PRC context. Vietnam / India / Mexico audits are a separate engagement with different scope. Email and we'll discuss.
At cost, against itemized receipts, within 14 days of report delivery. No markup. Typical range from US west coast to the Pearl River Delta is $2,500–$5,500 (flights, hotel, ground transport, visa fees if applicable). Quoted on the scoping call with a not-to-exceed cap in the engagement letter.
No quality engineering audit can guarantee that. What is guaranteed: the obvious failure modes, the process-capability gaps, the supplier-quality chain weaknesses, and the regulatory exposure issues visible on the day of the visit will be in the report — with photo evidence, severity tags, and the standards or recalls they tie to. What you do with the findings is your call.
That's one of the most important things this audit catches. If on-site observation shows the entity is a sales / trading entity rather than a factory, the Tier Classification opening of the report says so directly and the Next Step Card recommends sourcing alternatives. Better to learn it in the audit than after tooling commitment.
Then this isn't the right service for you — that's the Post-Launch CM Audit. Same engineer, same methodology spine, different framing: independent root-cause investigation, defect-rate quantification at the line, stop-sale decision support, and a backer-shareable findings report. Urgency-priced. Read that page or just book a scoping call and we'll route you to the right service on the call.
Book a free 20-minute scoping call. We'll walk through your CM, your timeline, and the audit shape that fits. If it's a fit, you'll get a one-page engagement brief and a 50% deposit invoice. If it's not, we'll tell you why and recommend the right path.
