How Do Workwear Brands Plan Reorders With an OEM Factory Without Running Out of Stock?

How Do Workwear Brands Plan Reorders With an OEM Factory Without Running Out of Stock?
A workwear reorder slips for one reason: the clock starts later than the buyer thinks. With an OEM factory, bulk production usually begins after you approve the pre-production sample and pay the deposit, and it then runs about 60 days. Trigger the workwear reorder when stock is already low and you are behind before the PO exists. Good workwear reorder planning does three things: it sets the trigger from the real lead time, it rebuilds the size curve from sell-through, and it locks the shade and fabric before the next run starts.

Workwear reorder planning starts at sample approval, not at the PO

Most buyers count lead time from the day they send the purchase order. That is not when production starts.
At our factory in Danjiangkou, Hubei, the sequence is fixed. We send a pre-production sample after the order is placed, and mass production only begins once you confirm that sample. Sample lead time is 7 days, and bulk production is 60 days after sample approval and deposit. If you change a color, logo placement or label, the sample is redone and that week moves to the front.
So the planning number for a workwear reorder is not 60 days. It is 7 days plus 60 days, plus the time your team needs to approve the sample and arrange the deposit. Call it 75 days of real cover. A workwear reorder plan built on 60 days is already two weeks short before anything goes wrong.

In-house production removes handoffs, but not the booking problem

Cutting, sewing, inspection and packing run at our own plant, with annual capacity of 3,000,000 pieces. That matters for a workwear reorder because there are no outside workshops in the chain, and quality checks happen at each stage instead of only at the end.
It does not mean capacity is always open. A plant running at high load during peak season will slot your workwear reorder behind confirmed programs. The earlier you place it, the better your date holds. That is why workwear reorder planning starts from the calendar, not from the warehouse shelf. Capacity booking belongs inside workwear reorder planning, not in a spreadsheet nobody opens until the shelf is thin.

The workwear reorder point is arithmetic, not instinct

Reorder point = average monthly sales x (real lead time in months + freight and buffer) + safety stock.
Take a simple case: 500 units a month, real lead time 75 days, about 2.5 months. Ocean freight and customs add another month. That is 3.5 months of cover before you touch safety stock, or 1,750 units. If your fast movers need four weeks of buffer, the trigger for the workwear reorder sits near 2,000 units.
At 2,000 units on hand, the workwear reorder goes out. At 800, you are negotiating air freight.
Workwear reorder planning holds up only when the formula uses the real clock, not the PO date. Two details decide whether the number works. First, use the lead time for the specific style: a hi-vis jacket and a plain work shirt do not share a production path. Second, update the number when your sales rate changes. A workwear reorder point set last year is a guess this year.

Rebuild the size curve for every workwear reorder

The first order is a forecast. The workwear reorder should be data.
Pull 60 to 90 days of sales by size. Compare units sold with units received. In most workwear programs, two or three sizes carry the volume, one or two sit, and the largest sizes sell in bursts when a new crew or site starts. Build the workwear reorder on the sold ratio, not the original ratio, or you will keep refilling the slow sizes.
Keep it per market. A US L is not an EU L, and the same size label in a jacket and a trouser does not fit the same body. Blending regions into one curve hides the problem instead of fixing it, and it is the most common mistake in workwear reorder planning. Most workwear reorder planning breaks here: the curve gets copied, not rebuilt.

Lock the shade and the fabric before the workwear reorder run starts

Two reorders of the same style can read differently in a store, usually because of a new dye lot or fabric batch.
Fabric is inspected on arrival and checked in-line during sewing, so a batch off weight or handfeel is caught before it becomes garments. Your side is the record: keep the approved swatch, the composition, the GSM and the finish, and ask for the same dye lot on the workwear reorder. If that lot is gone, approve a new standard before production, not after delivery. Shade control is the part of workwear reorder planning that buyers check last and their customers notice first.

OEM programs need the spec locked earlier than stock brands

Private label work is less flexible. Labels, hangtags, polybags, size markings and carton marks are all part of the order, and any late change holds up production.
Our OEM and private-label programs serve European workwear brands and industrial distributors, with Adeo, Portwest and Würth Group named on our About page. Those programs work because the specification is fixed before the sample is approved, and the workwear reorder repeats that approved specification rather than reopening it. For an OEM buyer, workwear reorder planning is a document exercise before it is a production exercise.
The practical rule: a workwear reorder should be a repeat, not a redesign. If you need a change, price it as a new development with its own sample and its own lead time, and keep the workwear reorder planning calendar untouched.

Checklist before the workwear reorder goes out

  • Workwear reorder point recalculated with 7-day sample and 60-day bulk
  • Sample approval and deposit time added to the clock
  • 60 to 90 days of sales pulled by size and by market
  • Size curve rebuilt from sell-through
  • Approved shade swatch and dye lot confirmed
  • Fabric record on file with GSM and finish
  • OEM labels and packing unchanged, or priced as a new run
  • Capacity slot checked against peak season
  • Freight mode and transit time inside the buffer
  • Workwear reorder planning reviewed with the factory every quarter
  • The workwear reorder reviewed on a fixed weekly or monthly rhythm
