Ask Achan: The biggest mistakes people make when implementing HubSpot

Dear Reader,
We've been getting a lot of questions lately about HubSpot implementation. Not the exciting kind ("How do we set it up?"), but the painful kind ("Why is our portal such a mess?").
Here's what's interesting: HubSpot is genuinely easy to set up. You can have a CRM live and see value in weeks. But that's also where many companies shoot themselves in the foot.
Let us explain.

We came across this question recently:

Here's what Achan says:

This is the paradox of HubSpot: it's so easy to launch that teams often skip the things that matter most in the long run. No data cleanup strategy. No governance. No field standards. No rollout plan. You get wins fast, but you build debt faster.

I've seen this pattern across dozens of implementations, and it always looks the same. Teams celebrate go-live. Then reality hits.

What goes wrong?

When you skip the fundamentals, three things happen. First, your data degrades. Duplicate records, inconsistent field definitions, stale information. Everyone's using the same CRM but working from different truths. Your reporting becomes unreliable and trust in the system depletes.

Second, governance disappears. Nobody owns data quality or enforces standards. And here's the critical part: if you've deployed HubSpot's AI features, they're working on bad data. Garbage in, garbage out. Your AI might confidently predict deal outcomes or recommend next steps based on records that are fundamentally inaccurate.

Third, your teams stop trusting the system. For example, sales doesn't trust the data, marketing doesn't trust the segmentation and finance doesn't trust the reporting. You've built a CRM that nobody relies on, which defeats the entire purpose.

All of this is preventable with a health check. 

Six key things to a successful HubSpot implementation 

Across the dozens of implementations my team and I have run, here’s the planning steps I think make for a successful CRM implementation:

1. Start with data cleanup, not go-live
Before you import a single record, audit your source data. Deduplicate, standardise and validate. Yes, this takes time and no, you shouldn’t skip it. Clean data early saves months of pain later, especially before you activate AI features.

2. Define governance from day one
Who owns what? What fields are required? What's the approval workflow? Write it down and enforce it, this is where strategy becomes real.

3. Standardise your required fields
You don’t need to standardise every field, just the ones that matter: company, lead source, deal stage, contact preferences. Get buy-in from every team and make them required in the UI.

4. Build a realistic timeline
You don't need to launch everything in month one. Phase one: core CRM and basic workflows. Phase two: integrations and advanced automation. Phase three: optimisation and scale. Give each phase time to stabilise before moving forward.

5. Do a health check before you scale
After phase one, pause. Audit what you've built and check things like data cleanliness or if your team is following the process. Fix issues before they compound – there could be good reasons for these that are a simple fix. A HubSpot health check done early saves you months downstream.

6. Plan for adoption, not just implementation
You can build the perfect system, but if your teams don't use it, it fails. Before you launch, think about change management. How will you train people? How will you encourage adoption? What resistance might you hit? And critically: who's accountable for making sure people actually use this thing? Implementation success isn't measured by go-live date. It's measured by adoption rate and data quality three months in.

 What if your portal is already a mess? 

If you're reading this and thinking your portal has been chaotic for three years, you're not alone. And it's fixable.

Step one: Get an honest assessment
Bring in someone objective to audit your portal. A HubSpot health check or audit will show you what's broken, what's at risk, and what's actually working.

Step two: Prioritise the fixes
Some issues are urgent (bad data breaking campaigns, duplicate records affecting AI). Some are important but can wait (optimising workflows, standardising fields). A good partner helps you separate urgent from important.

Step three: Clean and rebuild systematically
You can't fix a three-year mess overnight, but you can fix it methodically with minimal disruption to business if you plan it out into phases. Document everything as you go and if you can't explain how something works simply, it’s worth stopping and questioning.

Step four: Get ongoing support so it doesn't happen again
You don't need to hire someone full-time. Many of our clients work with us on a flexible basis: quarterly health checks, on-call support for tricky problems, ongoing optimisation work. You get help without the overhead.

Here's the honest truth about working with a partner:

Many companies successfully implement HubSpot on their own. It's genuinely doable. But most teams we work with tell us they underestimated how much time and energy it takes to get right, especially while running your business day-to-day.

Here's what we've learned from implementing alongside dozens of organisations.

• First, there are patterns to what goes wrong. We've seen the same issues repeat: teams rushing past data cleanup because they're excited to go live, governance decisions that seem small but compound over time, adoption struggles that nobody anticipated. We've learned these lessons firsthand. If we can help you avoid even one of those pitfalls, that's valuable.
• Second, sometimes you need someone outside your organisation to say the hard things. Not because we're smarter, but because we don't have the internal politics or pressure you do. When you're being pushed to launch before you're ready, it helps to have someone independent in the room saying "let's pause here."
• Third, we stay involved after go-live. Implementation isn't a one-time event. We care whether your teams are actually using the system, whether your data improves over time, whether you're seeing the value you expected. That ongoing support matters.

A partner typically helps you move faster because you're not figuring out fundamentals while you're building. That efficiency often pays for itself in the first few months. Whether you need support now or later, we're here.

Achan's top tip

"The best time to fix your HubSpot implementation is before you launch. The second best time is immediately after. The third best time is now. Don't wait another quarter wondering why your data is a mess. Get a health check done. It's the cheapest insurance you can buy."

— Achan Bedi, Head of HubSpot Delivery

HubSpot's ease of use is a strength. But speed without strategy leaves scars. The companies that win with HubSpot aren't the ones that launched fastest. They're the ones that implemented thoughtfully: clean data, clear governance, realistic timelines, real adoption planning, and the right support.

Whether you're launching HubSpot or realising things are messier than they should be, let's talk about a health check. That conversation might save you months of headaches.

Until then,
