How do I check a security installer’s relationships with equipment suppliers?

Ask for the dealer agreements, recent supplier statements and the names of every manufacturer or distributor the installer relies on. Then call the key suppliers, with the seller’s permission, and ask whether the account is in good standing and whether the terms carry over to a new owner.

Begin with concentration. If most hardware comes from one source, the installer depends on that source’s pricing, stock and goodwill. Ask what the alternatives are and whether the crew is trained on them. A crew certified only on one product line can slow down quickly if the supplier changes terms.

Next, read the dealer agreements for anything tied to the current owner: personal guarantees, territory limits, minimum purchase expectations and clauses that end the account when ownership changes. Ask for the payment history, any credit hold in the past, and open orders or unpaid invoices that would pass to you.

Look at how the installer handles warranty claims and returns. A supplier who slow-pays credit for faulty units can leave the installer carrying the cost. Ask to see a few recent claims from start to finish. Finally, meet the supplier reps with the seller present. Their comfort with a new owner is a real part of what you are buying. Have your lawyer review any transfer or consent requirement before you rely on the terms. Ask how long each supplier has held the account, too.

Key takeaways

  • Check how dependent the business is on one manufacturer or distributor.
  • Read dealer agreements for ownership-change and guarantee clauses.
  • Speak to key supplier reps before closing, with the seller’s permission.
  • Ask the supplier’s view of the account before closing, not after.
