Promise Versus Factory Floor: Verifying Real Output Before You Pay the Deposit

The quote says twenty-five days. The salesman says twenty-five days. The chart pinned in the factory office says twenty-five days. Then you walk to the packing line and count what actually came off it yesterday, and the number is not the number. That gap between the promise and the floor sinks more FBA launch dates than defects ever do, and it is visible long before the goods are — on the same visit that pre-shipment inspection in China starts with.

🧾 Where a promised calendar comes from

Across 2,000+ inspections a year, most late shipments we meet trace back to a lead time nobody ever verified. Most lead times are written by someone who has never run your model. The figure is built on the line they want to use, at the rate their best month produced, with your order inserted into a book that was already full.

A 620-unit-a-day line does not become a 1,500-unit-a-day line because a spreadsheet needs it to. It becomes one when the factory adds a second shift, buys another machine, or quietly hands part of the work to somebody else.

📋 Six things you can count in one morning

➗ The arithmetic: rate, not vibes

Build days equals your quantity divided by the rate you actually verified. Then add first-article approval, add a rework runway, add the inspection window, add inland transit to the port. Only then compare with the ship date.

A brief we ran for a folding-table order quoted 18,000 units, FOB $12.80, about $230,400, at 22 days on a claimed 1,500 units a day. On the floor, the line named in the quote was producing 620. Eighteen thousand divided by 620 is 29 build days — before five days of first-article and rework, three for inspection and two to the port. That is 39 against a 25-day ship date, with a national holiday week sitting in the middle of it.

💸 What the gap actually costs

There are only two doors when the dates collide. Split the shipment and fly the balance, or roll the container to the next sailing and watch an empty listing.

Air-freighting 3,100 units at about $8.90 a kilo lands near $27,500, against the single man-day at $169 that the capacity check cost. Rolling instead keeps the money and takes three weeks out of the selling season, which for a seasonal SKU is usually the more expensive choice of the two. Rolling is not free either: a seasonal SKU that misses its window rarely sells at a small discount — it sits until next year, and the storage clock starts the day it lands.

🔍 What this check is not

Honest boundary: a capacity check is a snapshot, not a warranty. A factory can add a shift the week after you leave; it can also accept a bigger order and push yours back. What the visit does is replace a hope with a measured rate, a count of machines, and a date code you saw with your own eyes.

It is also not a defect check. You can leave with a realistic calendar and still need a full inspection before the container moves.

🧭 Three factory shapes, three different risks

A single-line workshop showing you a spotless showroom is quoting a rate the line behind that showroom has never actually run. A mid-size factory with two lines and a full book will move your order the week a bigger customer calls. A large plant where your order is two per cent of one line is steady but slow to schedule — your date is real, but every change request waits behind somebody else's.

Knowing which shape you are facing changes what you write into the PO. The workshop needs a declared rate and a spare-unit contingency. The mid-size factory needs written notice before new orders land on your line. The large plant needs a slot booked weeks before the first carton is made, because nothing moves a scheduled plant except a cancelled order.

📞 Five questions for the planner, not the salesman

Ask for the production planner by role, and ask only questions whose answers contain numbers. What is the daily output on the line for this exact model? How many other orders are booked on that line inside my window? What was your on-time performance across your last three orders? When does my sample approval deadline fall? And what happens to my ship date if the sample comes back for a second round?

Salespeople answer with confidence. Planners answer with dates. The distance between those two answers is the risk you are buying, and it takes one afternoon to measure.

📝 Four lines to add to the PO

Reports come back typically within 24 hours, so the numbers are in your hands before the next production meeting. Declare what you verified, then make it contractual: a stated daily output rate and the line it applies to; a weekly output count sent by email; written notice before any new order is accepted onto that line; and a rework runway with a named consequence for the ship date. Factories respect a schedule that has numbers attached to it. When the batch finally runs, the number of units pulled for the inspection follows the same discipline: set the sample size with our AQL calculator rather than by habit.

❓ FAQs

Can I not just ask the factory for a lead time?

You can, and you will get one. A quote tells you what the salesperson believes; a capacity check tells you what the line produced yesterday. Only the second number survives contact with a full order book.

How do you verify a daily output rate?

Counters and packing logs for the last few days, cross-checked against work in progress at each station, machine cavity count and cycle time, headcount per shift, and the date codes on other buyers' cartons.

Is a capacity check the same as an inspection?

No. A capacity check reads the calendar and the floor; an inspection reads the product. A large order often needs both, and they can be booked as one visit when production is already running.

What if the real rate is lower than quoted?

You still have three choices before you pay the deposit: renegotiate the ship date, agree a split shipment, or move part of the order to another line. All three are cheaper now than after the container is booked.

How long does a capacity check take?

One day on site. Most of it is arithmetic — turning a claimed rate into build days, then into a ship date you can hold the factory to in writing.
