Reducing dependence on one big customer: how a logistics firm spreads its accounts
How a logistics firm measures its dependence on one large shipper and builds a simple account plan that adds smaller, steadier customers in steps without upsetting the big one.

You reduce dependence on one big shipper by measuring it first, then adding smaller accounts in a fixed order. Start with the lanes you already run, then the empty return legs, then customers near the ones you serve. Do it while the big account is healthy. A short target list and a steady calling slot do more than a one-off campaign.
How do you know you depend on one customer too much?
Do not wait for a share figure from a textbook. Run two checks from your own books.
First, take the last twelve months of billing and see what part came from the largest customer, and the largest three together. Second, run the pause test: if that customer stopped sending for two months, could you meet fixed costs from the rest? Drivers' salaries, vehicle instalments, godown rent, insurance, and your own pay.
If you cannot, you have a concentration problem however the share looks. A fleet with a large share from one account, a long contract and low fixed costs is safer than one with a smaller share, heavy instalments and late payments. The pause test is the more useful number.
Also look at dependence you do not see in the invoice: one plant, one decision-maker, one route. If the purchase head who likes you leaves, the account can move quickly.
What does the big customer do to your other work?
A large account shapes your trade in quiet ways.
- Vehicles. Your best trucks sit on their lane, and a new shipper gets what is left.
- Attention. Your dispatch desk learns their priorities and drops others.
- Rates. After a few years the rate has been negotiated down, and every other quote feels high to you, so you do not send it.
- Payment. A large customer's delays become your delays.
None of these is a reason to cut the account. They are reasons to build alongside it on purpose, with a dispatch rule that keeps some capacity and a diary slot for others.
Where do the next accounts come from, in order?
| Order | Source | Why it comes first |
|---|---|---|
| 1 | Shippers on the lanes you already run | You can quote with confidence and the vehicle is already moving |
| 2 | Shippers who can fill your return leg | An empty leg earns nothing, so any rate above cost helps |
| 3 | Neighbours of your current customers | Same industrial area, same gate, same dispatch network |
| 4 | Suppliers and buyers of your big customer | They know your name and have seen your service, if the big customer allows it |
| 5 | A second cargo type | A step into a new kind of load, only after the first four give steady work |
Work down the list. Row five looks bigger, and months can go on learning a new cargo while the nearer chances in rows one to three go untouched. The return-leg side is in how fleet operators fill idle vehicles.
For example: a fleet operator in Nashik
Here is an invented case. A Nashik operator runs eleven trucks, and about two thirds of the work carries goods for one distributor of packaged consumer products. The owner says: "They pay on time and send daily. Why look elsewhere?" Then the distributor renegotiates and moves part of its volume to a larger carrier. The trucks stand for a week, with no one else to call.
Taking the work was not the error. There was no list of other shippers, so one bad week left no options, and nobody tracked free vehicle-days to show whether the trucks could take more.
Afterwards the owner writes down, truck by truck, which days are committed to the distributor and which are free. A list of twenty shippers on the Nashik to Pune and Nashik to Mumbai lanes, from the industrial area near Ambad, is made, and Tuesday and Friday are set aside to call five of them. The distributor is told plainly that other loads will be taken on free days and that its own days stay protected. The distributor does not object. Over some months a few small accounts send loads most weeks, though at lower rates than the distributor paid, and one of them pays late enough that the owner has to refuse its next load. The distributor is still more than half the business, but the pause test now passes.
How do you make a simple account plan?
Use one sheet per customer you want to grow, and one for the target list. For the big customer: what they send, where, who decides, how they pay, when the contract ends, who else in their company could use you. For each small account: the lane, the load, the person, the next step, the date.
Then set the routine, which matters more than the plan. A free vehicle-day is a truck with no committed load and a driver available for that day; count them, because you cannot sell a day you have not counted.
- Count free vehicle-days for the coming fortnight, every fortnight.
- Call or message a fixed number of target shippers for those days.
- Record the answer, even when it is no, and the reason.
- Review the share and the pause test every quarter.
One caution on target lists. Think before you pitch the big customer's own competitors, and never use the big customer's name as a reference unless they have agreed. Being careless with that name while chasing small accounts puts the main account at risk.
When is it fine to stay concentrated?
Sometimes it is a choice. A dedicated contract fleet with a long agreement, fair payment terms and a clause for volume changes may suit you. The risk is real if the contract has no volume floor, if payment is slow, or if the shipper can end it at short notice. If you stay concentrated, set aside a reserve that covers the pause test and keep one live conversation with a second shipper.
Run the pause test this week
Open last year's billing, find the share of the top customer and run the pause test on a sheet of paper. If it fails, list ten shippers on the lanes you already run and call the first three. Steady relationships after a first win are covered in building a repeat relationship with a buyer, account management and key account growth is the closest service, and the trade is under logistics sales and marketing. If you want a second pair of eyes on the plan, tell us what you need.
