A business with one dominant customer can still be valuable, but the transaction depends heavily on contract strength, relationship continuity, profitability, and the buyer’s ability to retain or replace the account.

Many online businesses depend on Amazon, app stores, search engines, social networks, advertising platforms, payment providers, or software ecosystems. Buyers will evaluate how a policy or account change could affect the company.

Contracts determine whether revenue, suppliers, employees, technology, and services will continue after ownership changes. A seller should understand assignment, termination, liability, renewal, and change-of-control provisions before negotiations.

Buyers need confidence that the seller owns or can transfer the technology, content, brands, designs, and data that produce the company’s value. An intellectual property audit identifies gaps before they become transaction problems.
