Seller involvement post close

I came across a Reddit post on this and wanted to get some real-world perspectives from folks here. The situation in the post was a retiring seller (80+ along with his wife), where the wife wanted to stay involved part-time after the sale. The top advice there was not to let the seller linger too long, as it can create confusion with customers and employees, and can also undermine the buyer’s ability to take over. There’s also the SBA angle, where seller involvement is typically limited (around 12 months max). That said, I’ve spoken to a few buyers who are actually thinking of keeping the seller involved for longer. I'm in the process of acquiring a small manufacturing business that’s been run by the same owner for ~30 years. So this question is very real for me: How long should you realistically retain the seller post-acquisition? The seller believes the business has strong goodwill and will continue smoothly. But honestly, there’s no perfect way to validate that without actually owning and operating it. One thing I’m considering during due diligence is analyzing customer history, looking at the past 2–3 years of clients, repeat business, and concentration. If there’s a healthy spread and repeat orders, I’d feel more confident that goodwill is embedded in the business and not just tied to the owner. Curious how others have approached this: - How long did you retain the seller? - What worked (or didn’t)? - Any red flags I should watch for?

My bias would be to keep the seller involved long enough to transfer relationships and knowledge, but not so long that it creates confusion. In many cases that is probably 3 to 6 months, then a pretty quick taper. I’d focus diligence on whether customers, pricing, and key decisions are truly tied to the business or still tied to the owner.

Just giving my perspective here based on experience: In the wild, post-close - Keeping the seller on usually causes friction. That doesn't mean it always has to be that way but here's what I've seen: - It's awkward: the old owners don't know how to function in the business other than as owners and it can undermine the new ownership's authority. - Regardless of the contract language, sellers and buyers ultimately have different expectations as to what level of involvement is "appropriate" for the previous owners post-close. - It can really backfire if customers or employees perceive you as mistreating the owners in any way (note: whether you actually ARE mistreating them or not is a whole other issue - what matters here is how any conflicts are *perceived* by customers and team). Basically, there just seems to be a lot more ways that keeping the owner on can be problematic than there are benefits. A short training period with the previous owners is one thing, but I'm actually very surprised to see so many people considering keeping them on as part of the company post-acquisition. That's setting up a box of fireworks right next to an open flame. To people that have had this work successfully, props to you. But I would instead recommend that you do your due diligence pre-close, make plans to tackle any operational problems you were going to depend on the owner for, and rip the band-aid off. The previous owners have to go at some point, you might as well start that process when you become the new owner. Again, no offense to anyone that's made this work. It may be the region I'm in or circles I hang out in. Just trying to give some advice since it's such a big investment.
