A Major Client That Holds You and Chokes You

A client who brings most of your revenue can be a lifeline or a trap, and you should neither drop them in fear nor keep them at any cost. When a major client should go, and how to let go without panic.

A major client: dream and risk in one contract

A major client is every owner's dream, and also the biggest risk. One client bringing 30%, 50% or 70% of revenue can be a lifeline or a trap. If they leave, cut volume or switch suppliers, the company can vanish overnight, and you are left with salaries that must be paid on the first of the month.

How do you recognize the moment a major client should go, and how do you let them go without panic?

When a client should go, and when they should stay

A client should go when they are toxic, even though they pay. They humiliate your people, change requirements without notice, miss their own deadlines and use their position to push the price. Money does not justify toxicity, and a client who costs you your dignity costs more than they pay.

They should go too when they choke growth. They demand so many resources that you cannot develop other clients, keep your best people on a project that does not grow, and make you turn down other opportunities. The question then is not whether to let them go but when, because every month with such a client is a month without growth.

They should go as well when they blackmail you: asking for a discount to stay, threatening to leave to extract more. If you give in, you lose margin and dignity.

A client should stay when they pay a fair price and respect the agreement and your people. That is a partner, not a burden, and one rarely lets such a client go. They should stay when they open doors you cannot open alone, references, new markets and industries, because then they have strategic value even if the revenue is not the largest. And when they grow with you, widen the cooperation and invest in the relationship.

One client holds most of your revenue

One client holds most of the revenue. If you have no other of that size and cannot replace them in reasonable time, you depend on them. Dependence does not matter while it lasts, it matters when the client decides to leave.

The client dictates terms: price, deadlines, way of working. Then you are not a partner but a contractor, and someone who cannot negotiate is not a supplier but a dependant.

The client chokes the rest of the business. If they cost you more than they bring, that is not a client, it is a burden.

How to let a major client go without panic

Prepare months ahead. Find other clients, build a reserve, train the team. Look for a replacement right away, not after the client leaves, because then it is too late. A client should not leave overnight, because the company can fall apart that way.

Communicate openly and fairly. Say why, without accusations, humiliation or surprises. If they understand, they may recommend you, and the business world is small.

Protect the team with contracts, relationships and culture, especially if the client tries to hire your people. If the team leaves with the client, you have lost more than a client.

Be ready to lose revenue. If 30% of revenue leaves, that is 30% less in the account, and whoever is not ready for it should not let the client go. But enduring is expensive.

A client's size is not a measure of value

A client's size is not a measure of value. Whoever stays with such a client out of fear of losing revenue may lose both the revenue and the company. This decision calls for courage, not fear.

If a big client is asking for something you do not want to give, describe the terms, their share of revenue and your alternatives. You will get a structured report on options and risks.
