How do I judge whether an environmental firm’s work comes from repeat industrial clients?

Ask for project history by client over several years and see which industrial clients keep coming back, and why. Then look at how each repeat relationship began, whether it depends on one person, and whether the work is ongoing or tied to a single event. Repeat work is a better sign when it is routine.

Request a list of clients with every project the firm has done for each. Mark which ones returned and how often. Then look at what the repeat work was. A client who needs regular monitoring or reporting behaves very differently from one who needed a single clean-up and may not call again.

Next, ask how the relationship is held. Do the industrial clients deal with one named consultant, or with the firm as a whole? Do they have standing arrangements or approved-supplier status? If the client’s contact changes jobs, does the relationship continue? Ask the seller whether a few of these clients could speak with you before closing.

Consider the client’s own situation. Industrial customers can be affected by closures, ownership changes and shifts in their own business. Ask what share of the firm’s work depends on a single industry, and how the firm has handled slower years. Ask what the firm would do if its largest industrial client stopped sending work. A consultant, an accountant and your lawyer can each read this picture from a different angle, so use them. Ask also how the firm keeps in touch between jobs, since steady contact often explains repeat work better than any single project.

Key takeaways

  • Mark which clients returned and whether their work was routine or one-time.
  • Find out who holds each relationship and whether it survives a change of contact.
  • Check how concentrated the client base is in one industry.
