How to Get Clients for an IT Consulting Firm

To get clients for an IT consulting firm beyond referrals, sell into dates your buyers cannot move. Microsoft ends support for Windows Server 2016 on 12 January 2027 and SQL Server 2017 on 12 October 2027, and Windows 10 Extended Security Updates cost businesses US$61 per device in year one, doubling each year. Each date is a reason to take your call.

• The triggers: Microsoft’s published lifecycle dates. Windows 10 support ended on 14 October 2025; Exchange Server 2016 and 2019 ended the same day; SQL Server 2016 ended on 14 July 2026 (Microsoft).
• The money argument: a 40-device firm staying on Windows 10 pays US$2,440 for ESU year one, US$4,880 for year two and US$9,760 for year three, US$17,080 in total (our arithmetic from Microsoft’s US$61 year-one price and its doubling rule).
• The cheapest pipeline: proposals that went quiet. Work them before you buy a single cold contact.

Rules of thumb

• LeadsNow’s end-of-support countdown: open the conversation 12 months before the date, when the buyer can still budget for a project, and again at 6 months, when the project has to start.
• After the date, the conversation is about cost: Microsoft prices Windows 10 ESU at US$61 per device for year one and says the price doubles each year, for up to three years (Microsoft).
• If your meeting-to-client rate is 15%, you need 40 first meetings for six clients; at 35%, 18. Measure yours before you set an outreach target.
• At an assumed 4% meeting rate per account contacted, 24 meetings needs a trigger list of 600 accounts (24 ÷ 0.04).
• A product past its end-of-support date gets “no new security updates”, in Microsoft’s words: lead with that fact, not with your services list.

Which channels win IT consulting clients, and what each costs to run

IT consulting firms win clients through four channels: referrals, partner and vendor co-selling, outbound to named trigger events, and events, and each has a different cost and ceiling.

No credible public benchmark publishes sales-cycle length or cost by channel for IT consultancies, so the cycle and cost columns below are illustrative assumption bands, not measured figures: replace them with your own CRM numbers.

If you only change one thing, add the trigger channel, because it is the one you can switch on this week without anyone else’s permission. LeadsNow’s lead generation for consultants page covers how the same channels apply across consulting firm types, and what to do when consulting referrals dry up covers the referral decay arithmetic in depth.

Which end-of-support dates give an IT consultancy a reason to call

Microsoft’s published end-of-support dates are the strongest trigger events an IT consultancy can sell into, because after each date the product gets no new security updates.

Microsoft’s lifecycle pages say that on retirement or end of support there are “no new security updates, non-security updates, free or paid assisted support options or online technical content updates” (Microsoft lifecycle, 2027 list). That sentence is the whole pitch: a business still running the product after the date is carrying risk it did not choose. All dates below were read on Microsoft’s own lifecycle pages on 25 October 2026.

The end-of-support countdown is the decision rule that turns this table into a calendar: contact the account at 12 months (budget), at 6 months (project start) and in the month after the date (risk and ESU cost). A passed date is not a dead trigger: it becomes a cost conversation.

How the Windows extended security update price becomes an outreach argument

Windows 10 Extended Security Updates give an IT consultancy a priced argument, because Microsoft charges businesses US$61 per device for year one and doubles the price each year.

Microsoft says ESU for organisations is bought through Volume Licensing “at $61 USD per device for Year One” and that “the price doubles every consecutive year, for a maximum of three years” (Microsoft ESU page). Microsoft also says ESU comes at no additional cost for Windows 10 virtual machines in services including Windows 365 and Azure Virtual Desktop.

Year two and three prices are arithmetic from Microsoft’s doubling rule. Use the table in the first email: name the prospect’s approximate device count, show the three-year ESU total, and offer a fixed-scope assessment that prices the refresh against it.

How many first meetings an IT consulting firm needs a year

An IT consulting firm needs first meetings equal to its new-client target divided by its meeting-to-client rate, so six clients at 25% means 24 meetings.

The rates below are assumption bands, not benchmarks: no credible public source publishes a meeting-to-client rate for IT consultancies, so take yours from the last 12 months of your CRM.

The denominator matters most: a firm at 15% needs more than twice the meetings of a firm at 35% for the same six clients, so fix the discovery call before buying more outreach.

How partner and vendor co-selling brings IT consulting clients

Partner and vendor co-selling brings an IT consultancy opportunities from vendor sales teams and other partners, but only after the firm is enrolled and has something listed to sell.

Microsoft defines co-selling as “any collaborative engagement between Microsoft and its partner ecosystem”, including sharing sales leads, and names Partner to Partner (P2P) selling as one co-sell category (Microsoft co-sell overview). The same page says co-sell solutions “can include software built with your intellectual property (IP) and services that support Microsoft technologies”, so a services-only consultancy is not excluded, though the co-sell statuses apply to offers in Microsoft Marketplace.

• Start with P2P: a larger partner that resells licences but does not deliver migrations can pass on overflow work.
• Map accounts: bring shared accounts with a dated trigger, not a capability deck.
• Count the cost. Enrolment, an offer listing and account-mapping meetings can take months, so treat co-sell as a build, not this quarter’s pipeline.

Why your old proposals list is the cheapest pipeline you own

An IT consultancy’s list of proposals that went quiet is its cheapest pipeline, because those buyers already described the problem and saw your price.

Pull every proposal and assessment from the last 24 months that did not sign, and tag each with the product it involved. Many will now sit on the passed side of the end-of-support table, which gives you a new reason to write: the date they deferred has arrived. LeadsNow’s “trash to cash” model is one example of working given-up leads: a coaching and consulting client closes around $180,000 a month in cash collected purely from leads it had given up on and handed to LeadsNow, such as no-shows and meetings that did not close. That is one anonymous client, not a benchmark. LeadsNow’s database reactivation page explains the method.

What running client acquisition yourself costs, and when to hand it over

Running trigger outreach yourself costs an IT consulting firm mainly owner or senior engineer hours, which is the same time that would otherwise be billed to clients.

Using the middle case above, a 600-account trigger list at an assumed 10 minutes of research and writing per account is 100 hours before any follow-up. If your billable rate is $150 an hour, that is $15,000 of billable time for one pass of the list. Add a contact data subscription, a sending tool, and the follow-up: replies arrive while you are on a client site.

• Do it yourself if your trigger list is under about 200 accounts, you have one technical seller with spare hours, and your close rate is high enough that 10-20 meetings fill the year.
• Hand over the booking when the list runs to many hundreds of accounts, when replies sit unanswered while you deliver, or when old proposals and no-shows are piling up untouched. See AI appointment setting.

Frequently asked questions

How do IT consulting firms get clients without referrals?

Add three controllable channels to referrals: outbound timed to dated triggers such as Microsoft end-of-support dates, partner co-selling, and a worked list of old proposals. Size it first: new clients wanted divided by your meeting-to-client rate gives the meetings you need.

When should an MSP start outreach before an end-of-support date?

Start about 12 months before the date, when the buyer can still budget, follow up at 6 months, when a migration has to start, and write again in the month after the date. For Windows Server 2016, ending on 12 January 2027, the 12-month window has already passed, so lead with the risk and cost.

How much do Windows 10 Extended Security Updates cost a business?

Microsoft prices Windows 10 ESU for organisations at US$61 per device for year one through Volume Licensing, and says the price doubles every consecutive year for a maximum of three years (Microsoft ESU page). That makes US$427 per device across all three years.

Is Microsoft co-sell open to services-only IT consultancies?

Microsoft says co-sell solutions can include software built with your own IP and services that support Microsoft technologies, and lists Partner to Partner selling as a co-sell category (Microsoft co-sell overview). Co-sell statuses apply to offers in Microsoft Marketplace, so plan the listing work first.

How many sales meetings does an IT consulting firm need?

Divide your new-client target by your meeting-to-client rate: six clients at 25% needs 24 first meetings, at 15% it needs 40. Use your own CRM data, because no credible public benchmark exists for IT consultancies.
