Why most MSPs are sitting on untapped revenue 

Here's something nobody really talks about in MSP sales: the easiest conversation you might ever have could be with someone who already said no to you. Not a cold prospect who has never heard of your business. Not a lead who needs six months of nurturing before they will take a call. A former client, someone who already trusted you enough to hand over their IT infrastructure, who left for a competitor. 

I've seen this play out across the channel more times than I can count, and it surprises people every time I bring it up. An MSP loses a client, usually to a provider who made bigger promises or came in cheaper, and then three to six months later that former client is sitting there quietly wondering if they made the right call. The new provider over-promised. The account manager who sold the deal has moved on. And the MSP who lost them? They never followed up. Not once. What tends to happen is that the door stays open far longer than most people assume. Your silence during that period sends a message, and not a good one. 

The reason I mention this is that re-engagement is not the desperate, awkward conversation most MSPs imagine it to be. Done well, it is one of the most natural things in the world. 

Why former clients are worth your attention 

Think about what it took to win that client in the first place. Discovery calls, proposals, site visits, pricing conversations, onboarding. Months of work, sometimes more. Now think about what happened when they left. In most cases, MSPs send a polite offboarding email, make a note in the CRM, and get on with their day. 

But your former client did not stop having IT problems the day they left you. They took those problems to your competitor. And three to six months in, a significant number of them are quietly asking themselves whether they made the right decision. The new provider has dropped a few balls. Support tickets are taking longer to resolve. The account manager who sold them the deal has moved on to a different patch. The onboarding, if there was one, was rougher than expected. These are often the exact same frustrations that brought them to you in the first place. 

What I've found is that your silence during this period tells them something. It tells them you did not care enough to check in, even professionally. Meanwhile, your competitor is already giving them reasons to look elsewhere again. The irony is that you are better positioned than almost anyone to win that business back, and most MSPs do not act on it. 

The psychology behind a win-back 

Client re-engagement is not really about sales tactics. It is about relationships, and relationships do not end cleanly just because a contract does. Most people feel a bit awkward after they leave a supplier. They made a decision, they justified it internally, they told their team it was the right move. They are not going to be the first to admit things are not working out. 

Your job is not to make them feel bad for leaving. It is to make it easy for them to come back. And the biggest mistake I see MSPs make with win-backs is leading with something that feels like desperation. Discount offers. Subject lines that say 'We miss you.' Emails that make it obvious you are chasing the revenue rather than the relationship. Former clients can spot that from a mile away, and it tends to confirm exactly why they left. 

The shift worth making is this: you are not asking for a second chance. You are a capable, improving provider extending a professional olive branch. There is a real difference between those two things, and former clients feel it. 

What re-engagement looks like in practice 

1. Think about timing before you do anything else 

The three-to-six month mark is generally where I have seen the most traction. Long enough that the initial awkwardness has faded on both sides. Close enough that the honeymoon period with the new provider is likely to be over and the reality of day-to-day support has set in. What tends to happen at that point is a kind of quiet buyer's remorse. Nothing dramatic. Just a sense that things are not quite as good as they were promised to be. 

Waiting a full year makes the conversation harder. By then, the client has fully committed, switching costs feel significant, and the emotional distance from their time with you has grown. Earlier is nearly always better, within reason. 

2. Do your homework before you reach out 

Before you send anything, take a few minutes to think about why they left. Was it price? A specific gap in what you were delivering? A personality mismatch? A competitor who came in with a flashier pitch? Whatever it was, something will have changed on your end in the months since, even if you have not been formally tracking it. New tooling, faster response times, an improved onboarding process, a new team member, an expanded security offering. The reason I mention this is that if you cannot identify at least one concrete improvement, that is useful information too. It means the root cause has not been addressed, and the re-engagement attempt is premature. 

3. Lead with the relationship, not the departure 

When you do reach out, do not open with a reference to them having moved to another provider. That immediately puts them on the defensive and frames the whole conversation as you trying to convince them they made a mistake. What I've seen work much better is opening by acknowledging the time you worked together and referencing something specific from that relationship. A project you delivered well. A problem you solved together. Something that reminds them why they chose you in the first place. The departure does not need to be mentioned at all in your first touchpoint. 

4. Offer something genuinely useful with no strings attached 

This is where I see a lot of MSPs trip up. They offer a 'free consultation' that is really just a sales call in disguise, and former clients know exactly what that is. What tends to work far better is offering something with real standalone value. A cybersecurity health check is one of the strongest re-engagement angles I have seen. It is genuinely useful, it shows that your capability has moved on, and it gives a former client a low-pressure reason to re-engage without feeling like they are admitting they made a mistake. A licensing audit or a brief benchmarking report on how their current setup compares to best practice for a business their size can work just as well. The key is that it has to be something they can use regardless of whether they come back to you. 

At enhanced.io, a cybersecurity health check is something we help MSPs offer as exactly this kind of entry point. It gives you a professional reason to re-engage, a genuine deliverable for the client, and a natural conversation about where their security posture stands today. 

5. Make the next step as easy as possible 

Do not ask for a commitment, a meeting, or even a call in your first re-engagement touch. Ask a simple question or offer a resource that requires nothing more than a reply. 'Would it be useful if I sent this over?' is a very different ask from 'Can we jump on a call next week?' The goal of the first touchpoint is to reopen the line of communication. That is it. The conversation can develop naturally from there, and it usually does if you give it space. 

6. Follow up, but give it room to breathe 

If you do not hear back, follow up once more after a week or so. Keep it brief and warm and make it easy to respond. After two attempts with no reply, give it another month and try a different angle, perhaps a relevant piece of content or a new service you have launched, rather than another direct outreach. What you should not do is give up after one email. Most win-backs do not happen on the first touch. They happen because you stayed visible, stayed professional, and happened to be there when the timing was finally right for them. Does that make sense? It sounds simple, but it is genuinely where most MSPs drop the ball. 

What the bigger picture looks like 

Re-engagement should not be a last resort you reach for when the pipeline is quiet. It works best when it is a consistent part of your sales rhythm, sitting alongside your new business efforts and your renewal conversations. Former clients are warm leads in a way that almost nothing else in your pipeline is. They know how you operate. They have seen your team in action. The trust-building phase is largely done. You are reminding them why it existed, not trying to establish it from scratch. 

For MSP sales teams, the question is not really whether it is worth pursuing former clients. From what I have seen across the channel, it almost always is. The question is whether you have a consistent, professional process for doing it, or whether you are leaving revenue on the table because you assumed the door was shut when it was actually just ajar. 

Most of your competitors are not following up. That alone is your advantage.
