The Second Order Is Where the Margin Actually Comes From

When to Reorder Is Arithmetic

Most first-time importers reorder when the stock looks low, which is a feeling, and it arrives late. The reorder point is a number: average weekly sales multiplied by the total lead time, plus a buffer for the weeks when sales are above average.

Two figures are needed and both come from the first shipment. The first is real lead time, measured from the day the deposit left to the day the goods were available to sell, not from the day the supplier said production would finish. The second is the actual selling rate, from your own sales data rather than the plan.

With those two, the reorder point is a division. A product selling twenty units a week with a nine-week lead time needs a hundred and eighty units in the pipeline before the next order is placed, plus a buffer for variation. A buyer holding fifty units and ordering when they hit twenty has built a two-week stock-out into the plan.

Four Parts of Lead Time

Replenishment lead time is not the supplier's production time. It is four periods added together, and only one of them belongs to the factory.

• Order to production start. Deposit receipt, material purchase, scheduling. One to three weeks, longer if the material is made to order.
• Production. The figure the supplier quotes. Two to five weeks for most consumer goods, longer for furniture and anything with a tooling step.
• Booking and loading. One to two weeks, longer in a peak period or around a holiday, and longer again if the goods miss a cut-off.
• Transit and clearance. Four to seven weeks by sea, three to eight days by air, plus a week for clearance and delivery at destination on a good day.

The sum is usually six to ten weeks by sea. A buyer who plans against the production figure alone plans against a third of the timeline, and the shortfall appears as an air freight bill or an empty shelf.

Safety Stock Without a Spreadsheet

Safety stock covers the two things that always happen: sales above the average, and a shipment that arrives late. It does not need a statistical model to be useful.

A workable method for a small importer: take the worst week of sales in the last quarter, subtract the average week, and multiply the difference by the number of weeks you would like to survive a late shipment. Three or four weeks is a reasonable target for a product with a nine-week lead time. For a product with a two-week air lead time, one week is enough.

Then treat the result as a floor rather than a target. Stock should not fall below it without a decision being made, and the decision is usually to ship air freight or to accept a stock-out deliberately.

Two adjustments are worth making. Products with a short shelf life or a seasonal window need less safety stock and earlier commitment, because holding them is itself a risk. Products with a long life and steady demand can carry more, and the cash tied up is the price of never being out.

One more figure belongs in the calculation and is usually left out: the cost of holding the stock. Storage, insurance, the capital tied up and the risk of obsolescence together are rarely less than fifteen percent of the goods value a year, and on fashion or seasonal goods much more. Safety stock that prevents a stock-out is worth paying for; safety stock that sits through a season change is a write-down waiting to happen.

The way to keep both is to hold the buffer in the product that turns over fastest and to hold less of anything with a date on it. A range of ten items rarely needs ten buffers of equal size.

The Band You Should Be Moving To

The second order is where a price conversation is legitimate, because the buyer now has a shipment history and the supplier has a reason to protect the account.

Three things can move, and only one of them is the unit price.

The band. If the first order was a trial below MOQ, the second order should be quoted at the first real band. Ask what quantity opens the next band, then decide whether that quantity is sellable within the shelf life. Buying a container to save four percent and holding half of it for a year is not a saving.

The packing. Cartons, pallet configuration, inner packing. A change here often saves more in freight than a price negotiation saves in goods. On a volume product, five percent less carton volume is five percent less freight on every future shipment.

The terms. A supplier who has been paid in full twice may accept a lower deposit, or a balance against a copy bill of lading instead of before shipment. That is worth more in cash flow than a cent off the unit price.

Ask for the band structure in writing rather than for a discount. A supplier who sends a table of quantities and prices has told you what the next three orders should look like, and it is a table you can plan a year against. A supplier who sends a single reduced number has given you a negotiation, not a plan.

What to Change on the Second Order

The first shipment produced a list of small failures. The second order is the only chance to fix them cheaply, because after the third the process has set.

• Marking. Carton marks that were handwritten or missing should be printed to a specified format, with the purchase order number on every carton.
• Packing. The damage found on arrival, addressed with an insert, a divider or a stronger board grade.
• Documentation. Invoice and packing list templates agreed once, so the same fields appear in the same order every time.
• Inspection point. A production sample pulled from the first hour of the run, kept by both sides, if that did not happen on the first order.
• Reporting. A photograph of the loaded container and the seal number, sent before departure, as a standing requirement.

Put all of it in the purchase order rather than in an email. A change that lives in a chat message survives until the salesperson changes job.

Telling the Factory What Is Coming

A factory schedules its line on the information it has. A buyer who orders two thousand units twice a year is a small account that gets scheduled when there is space. A buyer who says "two thousand every quarter, here is the next three quarters" is a programme, and programmes get capacity reserved.

A forecast is not a commitment and should say so on the page. Suppliers understand the difference; what they want is to know whether to hold material, whether to keep the mould on the floor, and whether to plan a production slot. A twelve-week rolling forecast with a firm eight-week window is the version most factories can work with.

The return is not only scheduling. A factory that expects a repeat order of a known product will often hold a material buffer, which shortens the pre-production period by a week or two. On a six-week total, that is the difference between reacting to demand and planning for it.

Combining Reorders

Once a buyer has two or three products from two or three suppliers, the cheapest improvement is often not a price negotiation but a consolidation.

Two half-container orders become one full container with one set of documents, one booking and one trucking movement. The saving is not only the freight per unit; it is the fixed costs that attach to every shipment regardless of size: declaration, documentation, terminal handling, customs brokerage and delivery.

The constraint is timing. Goods must be finished in the same window, and the window is decided by the slowest supplier. Where the timing does not fit, a partial consolidation still works: the fast goods wait at a warehouse for a week, which costs storage and buys a container.

The rule of thumb is that consolidation pays whenever the combined volume crosses into the next mode: two LCL shipments becoming one FCL, or several small air shipments becoming one consolidated air booking. Below that threshold, the handling cost of waiting cancels the saving.
