Why does drop size decide whether a diaper wholesale route makes money?

Drop size decides route profitability because gross profit per stop scales with the order while the cost of making the stop barely moves. A stop carrying $500 of diaper wholesale stock returns about $100 of gross profit at a 20% margin. The same stop carrying $200 returns $40, against a service cost that stays close to $40 whatever is on the van. Below that line, every extra store makes the route worse.

Most new distributors in the region build coverage first and economics second: sign as many independent stores as possible, then discover that a van doing nine small drops a day cannot pay for its driver. The arithmetic is not subtle once it is written down, and it is the same arithmetic a supplier uses when deciding whether a territory is worth protecting.

Why does drop size matter more than the number of stores?

Because delivery cost is per stop and gross profit is per dollar sold. Doubling the number of stops doubles cost almost exactly. Doubling the average drop doubles gross profit without touching the number of stops.

A distributor with 100 stores on a two-week cycle and an average drop of $500 turns over $100,000 a month. A distributor with 250 stores and an average drop of $180 turns over $90,000 a month on two and a half times the delivery activity. The first business keeps more of what it invoices, and it needs less working capital per dollar of diaper wholesale revenue to do it.

What does one delivery stop actually cost?

Roughly $40 all-in for a city route. That is the cost to serve one account, and it is worth breaking into its parts because only one part is visible on a fuel receipt.

• Vehicle and driver time: $9-15 per stop on a route that completes nine to eleven stops a day.
• Warehouse and handling: rent, pickers and shrink spread across monthly drops, typically $8-14 per stop.
• Admin and credit control: invoicing, collections and returns handling, $5-9 per stop.
• Sales coverage: the merchandiser or sales rep visit that generates the order, $8-12 per stop.

None of these four lines falls when the order is small. That is the whole problem with a thin route, and it is why a distributor who manages gross margin without a cost to serve figure is usually surprised by the month-end result. Two distributors can report the same margin and earn very different money.

How much sell-in must one drop carry to cover itself?

Divide the all-in cost per stop by the gross margin percentage. At $40 per stop and a 20% margin, a drop needs $200 of sell-in just to break even on delivery, and $270 at a 15% margin.

Work the numbers for a carton of tape diapers. A 20GP holds roughly 48,000 pieces, and landed cost typically sits between $0.18 and $0.28 per piece depending on specification, freight and duty. At a landed cost of $0.22 per piece, a 30-piece pack costs about $6.60 to land and sells in at around $8.25 on a 20% margin. A carton of six packs is therefore worth about $49.50 of sell-in, and a store ordering four cartons is a $198 drop. That is right on the break-even line before the distributor has paid a single overhead bill.

This is the reason mature distributors push a store from four cartons to eight rather than adding a fourth delivery day. The second four cartons carry the same delivery cost as the first four and drop almost straight to the bottom line.

How many stores does a route need before it pays for itself?

Take a route with $6,000 a month of fixed cost covering driver, van, warehouse space and a sales rep, and a target of $2,000 operating profit. At a 20% gross margin the route must invoice $40,000 a month, which is the same cost to serve calculation run from the top down.

• At a $250 average drop: 160 drops a month, or 80 stores ordering twice monthly.
• At a $400 average drop: 100 drops a month, or 50 stores.
• At a $180 average drop: 222 drops a month, or 111 stores, on a route that will struggle to complete them.

The same $40,000 of revenue needs 80 stores or 111 stores depending entirely on drop size, and the 111-store version costs far more to serve. Store count is an output of the model, not an input.

Why do small stores order small drops, and how do you change it?

Small stores order small because they are protecting cash and shelf space, not because they dislike the product. Route density is the constraint on the distributor's side: nine small drops a day in heavy traffic cost more than nine large ones. Three levers move the account without discounting.

1. Fix the cycle. A firm two-week order date replaces ad hoc top-ups, and the store plans cash around it.
2. Set a minimum order value. Publish it with a delivery charge below the threshold. Most accounts consolidate rather than pay.
3. Bundle a second category. Wet wipes, facial tissue and cotton towels travel in the same carton space and lift the drop without another visit.

Each of these raises the value of a stop the distributor was already making. None of them requires a price concession, which matters because a discount given to win a bigger drop is usually worth less than the delivery cost it saves.

Which commercial terms protect a thin route?

Price breaks should follow drop size, not annual volume, in the first year, because drop size is what protects route density. A diaper wholesale schedule that rewards a $500 drop more than a $200 drop teaches the account to consolidate without a negotiation.

Three terms do most of the work: a published minimum order value, a delivery surcharge below it, and a clear returns policy that keeps reverse logistics out of the same van. Terms of this kind belong in the supply discussion before the first container, alongside the payment schedule and the territory definition. The onboarding sequence in our distributor onboarding guide sets out where each term is normally agreed.

When should a distributor drop a store instead of chasing volume?

When the store's annual gross profit is below the cost of the stops it consumes. A store buying $150 twice a month generates about $720 of gross profit a year against roughly $960 of service cost. It is not a small customer, it is a subsidy.

The honest options are to move it to a sub-distributor, convert it to a longer cycle with a larger order, or release it. Coverage maps that count doors without counting drops flatter a territory and hide the stores that are quietly paying for the rest, which is why route density belongs in the territory plan rather than in the month-end review.

For distributors planning a territory from scratch, the channel structure in our Southeast Asia distribution guide shows which door types carry enough volume to justify a direct stop. Where a market cannot support direct coverage, the partner programme is built around sub-distribution for exactly that reason.

Frequently asked questions

Is drop size more important than gross margin?

They multiply. A 15% margin on a $500 drop beats a 25% margin on a $200 drop, because the delivery cost is the same in both cases. Manage the pair together rather than negotiating price in isolation.

Does a bigger van solve a thin route?

No. Capacity is rarely the constraint on a city route; stop count and stop value are. A larger vehicle only helps when the constraint is cubes per stop, which is a different problem.

Should delivery be outsourced to a third-party courier?

It can work for remote accounts and for small repeat orders, and it converts a fixed cost into a variable one. What it does not do is build shelf presence, which is why most distributors keep their own van on dense routes and outsource the tail.

How does drop size affect the price a distributor can offer?

Directly. A store that takes a full pallet is cheaper to serve than four stores taking a quarter pallet each, and part of that saving can be passed on. Pricing that ignores drop size subsidises small accounts with large ones.

Bottom line

Route economics are decided by the value of an average stop, not by the number of doors on a map. At roughly $40 per stop, a drop below $200 of sell-in loses money at any margin a distributor can realistically keep, and the cost to serve figure barely moves however many stores are added to the map.

Fix the ordering cycle, set a minimum order value and bundle a second category before adding territory. A route with 80 well-sized drops will out-earn a route with 150 thin ones every month of the year. Formal pricing, MOQ and territory terms are confirmed per market through the partner enquiry form.
