How to choose a HubSpot consultant

There are thousands of HubSpot Solutions Partners. Their websites say roughly the same things, in roughly the same order, with roughly the same badges.

That's not much to choose from. So here's what actually separates them, written by people who compete in this market and would rather you hire well than hire us badly.

Start with what you actually own

Before you talk to anyone, write down which Hubs you have and on what tier. Marketing, Sales, Service, Content, Data, Revenue — and the tier for each.

This matters more than it sounds. There are 3,072 possible tier combinations across the six Hubs, and 1,024 of them include at least one Enterprise Hub. Two companies that both say "we're on HubSpot Professional" can be running fundamentally different software, with entirely different tools available.

Then use it as your first filter. If a consultant offers to scope your project without asking what you own, they're scoping a portal they imagined. That single question tells you a great deal about how the engagement will go.

Questions to ask before you sign

"What's the deliverable, specifically?"

A good answer names an artifact: a documented workflow inventory, a migration with engagements date-stamped correctly, a trained team with a playbook. A vague answer — "ongoing optimization," "strategic partnership" — means the scope will be defined later, by them.

"What happens when you're done?"

Ask what documentation you get. Ask whether an internal admin could maintain the build without calling them. A consultant who's built a system only they can maintain has built themselves a subscription, not a solution.

"Who is actually doing the work?"

At larger agencies, the person in the sales call is frequently not the person in your portal. Ask directly. Ask how many years the person doing the build has been in HubSpot — not the firm, the person.

"Have you worked in my situation?"

Not your industry, necessarily — your situation. Inheriting a portal from a previous agency is a different job than a greenfield implementation, which is a different job than a Salesforce migration with ten years of history attached.

"What do you think is wrong before you start?"

Anyone who's done this a while has a hypothesis after twenty minutes of conversation. If they have no opinion at all, they may be new. If they have total certainty before seeing the portal, they're selling.

"What would you tell me not to do?"

The most useful consultants talk you out of things. If everything you propose gets enthusiastic agreement, you're talking to a salesperson.

Scoped project vs. open-ended retainer

Both are legitimate but can fail in different ways.

Scoped Project

A scoped project has a defined deliverable and an end. It fails when the scope was written too narrowly, and you discover mid-build that the real problem was upstream. Protect against this with a paid discovery phase that's allowed to change the scope.

Retainer

A retainer buys ongoing capacity — good when your portal genuinely changes every month, when you have no internal admin, or when you want a standing person to call. It fails when it quietly becomes a subscription nobody reviews. Protect against this by asking, every quarter, what was delivered.

Our own view: most companies should start with a scoped audit or project, and only move to a retainer once they know what they're actually buying. Signing a twelve-month retainer before anyone has looked inside your portal is buying a solution before diagnosing the problem.

Solo consultant, small shop, or big agency

A large agency makes sense when you need many disciplines at once — paid media, creative, content production, web development, and CRM, coordinated across a team. You're paying for capacity and coverage. You're generally not getting the senior person full-time.

A small shop or solo consultant makes sense when the problem is deep rather than wide: a portal that needs untangling, a migration that has to be right, a team that needs training from someone who's actually run a sales team out of HubSpot. You get the senior person directly. You do not get five specialists on standby.

Neither is better. They're different purchases. The mistake is buying agency breadth when you needed depth, or hiring one person for something that genuinely needs a team.

What certification means, and what it doesn't

HubSpot Solutions Partner

A HubSpot Solutions Partner is a firm registered in HubSpot's partner program.

Certified HubSpot Implementation Provider

A Certified HubSpot Implementation Provider has passed HubSpot's requirements to deliver onboarding, which is what allows the standard HubSpot onboarding fee to be waived when you buy through them.

Partner tiers

Gold, Platinum, Diamond, Elite — are driven substantially by sold revenue and managed customer volume, not by the quality of any individual build.

So: certification tells you a firm is real, registered, and has met a bar. A high tier tells you the firm is large or sells a lot. Neither tells you whether the person assigned to your portal is good.

Use certification as a floor, not as a ranking. Then evaluate the person or team you would be working with.

Red flags

  • A proposal before a discovery call. They're scoping from your website.

  • No questions about your Hubs and tiers. Covered above. It's the tell.

  • Requiring permanent Super Admin access. They should tell you exactly what permissions they need, and be willing to be removed on delivery.

  • A fixed methodology applied to every client. Portals aren't standard. Neither are audits.

  • Migration quoted without a conversation about engagements. If nobody has asked how your historical calls and emails should come across, that data is at risk.

  • You can't find out who does the work. See above.

What it costs

Pricing in this market varies enormously by scope, seniority, and region. As a rough orientation:

  • Focused audit (about an hour, one specific problem): $250

  • Full portal audit across Hubs: $400-$1000

  • Implementation or migration project: $500-$10,000

  • Monthly retainer: Depends on hours

  • Hourly / on-demand support: $150/hour

Three notes on structure, which matter more than the numbers:

  1. Scope the audit before you buy it. You shouldn't pay for a review that's too narrow to be useful or too broad to be worth it. That's what a discovery call is for.

  2. An audit should be a standalone purchase. The findings should be yours whether or not you hire anyone to fix them. If the audit is free, it's a sales call — and the findings will point toward a project.

  3. Cheap migrations are the expensive kind. The most costly cleanup work we do is fixing migrations that were quoted low by someone who didn't know what they were taking on.

When we're not the right fit

We work with startups and midsize teams. If you're a large enterprise — hundreds of seats, multiple business units, a dedicated internal RevOps team, procurement and security review — you should be talking to one of the large partners with the staffing and process to match. That's a real difference in what you need, not modesty.

We're also not the right choice if you want someone who will agree with everything. Half of what we get hired for is telling people the thing their last consultant wouldn't.

If you want a second opinion

We're happy to be that, even if you end up hiring someone else. Tell us which Hubs and tiers you're on and what's bothering you.
