What I’ve Seen In Dozens of Implementations

I’ve witnessed and participated in dozens of inventory management system (IMS) implementations, and I can tell you one thing for certain: they’re hard work.

A successful implementation demands that people, systems, processes, money, and time all come together at once, in the right order. If you drop one, the whole thing can unravel.

Yet, for all its complexity, the implementation process can be tamed. It’s something I’ve seen firsthand over and over again, and without fail, there comes a moment when the operator stops fighting the system and starts trusting it.

Have you been on the fence about replacing your ageing, unintegrated systems with a connected IMS but have fears about the implementation process? You’re in the right place.

Today, I’ll share with you three phases every implementation usually goes through and how you can effectively steer your business and your team through each one.

Three Phases of a Successful Implementation

Every implementation follows the same arc. Knowing what's coming makes all the difference. Most (though not all) of us crave predictability and reject uncertainty, which is why the first stage revolves around people.

Phase 1: The Resistance Moment

Have you resisted buying an automated can opener because the manual one gets the job done or kept an old, ratty t-shirt that’s only fit for the garbage because it’s your most comfortable?

That’s what it’s like for your team when you ask them to let go of the current system. Even if it’s broken.

Spreadsheets are familiar, and manual workarounds feel controllable. Your team members have figured out how to make everything work. It’s what they know, and fear of the unknown leads to resistance.

As organizational psychologist Ronald E. Riggio puts it, “people tend to shy away from change because they are fearful or anxious about what the result might be.”

How do you combat that fear? By having clear credible information about the why’s, how’s and when’s and communicating them early and often. This is change management in practice: a plan for helping your team accept the transition and fully adopt the new system. It should be in place before implementation begins, not after resistance shows up.

You should also be waxing poetic about the concrete benefits of the new software. Here’s an example: instead of spending 16 hours per week manually syncing inventory across disconnected systems (which costs the business almost $21,632 per year), they could focus their time on strategic tasks that help grow the business.

Resistance is a normal part of the process. It’s a rational response to uncertainty. The businesses that come out ahead aren’t the ones who skip this phase; they’re the ones who give their team space to move through it.

Phase 2: The First Trust Moment

Trust is a small word with big meaning and building it in a new system takes time. But I've watched it happen repeatedly, and when it does, it's a turning point.

It almost always starts with something small and specific:

• Accurate stock counts across multiple locations and correct inventory deductions as stock begins to move
• Price tiers are showing correctly in the B2B portal for wholesale customers
• Accurate landed costs and COGS that are right the first time, without anyone having to verify them elsewhere

You’ll start hearing things like, “I checked the inventory count, and it was right without having to verify it anywhere else!” Or “I got a low-stock alert before we ran out instead of hearing about it from a customer complaint!” These comments are the signal. Trust in a new system isn’t built through training sessions or onboarding checklists. It’s built through small, repeated moments of accuracy your team didn’t expect but come to rely on.

The team at Hair Co., a leading importer and distributor of beauty and barbershop products, discovered this for themselves.They struggled with Excel for managing their growing inventory and forecasting needs. After implementing a modern IMS, they saved time, gained accurate inventory levels, and with a few clicks of a button, created forecasts that predicted inventory three to six months in advance.

The team now trusts their numbers, which means they trust their new system. And that trust led to a 10% increase in sales.

“It changed my life,” says General Manager Dion Alessi.

Phase 3: The Shift In How You Work

After enough trust moments, something more fundamental changes. You stop double-checking the systems against spreadsheets. You stop building manual buffers into your reorder points. And you start making decisions you couldn’t make before:

• Faster reorders
• More confident channel expansion
• Better supplier conversations

This is what it looks like to work from data you believe in. As that confidence grows and the benefits begin rolling in, something else changes: business performance improves, customer satisfaction increases, and growth becomes possible in ways it wasn’t before.

These downstream effects flowing directly from operational confidence can spur tremendous growth, like it did for Workplace Depot.

Workplace Depot, a UK-based supplier of workplace equipment, was using antiquated systems to stay on top of inventory levels and customer data. When they implemented a connected IMS, business began to boom.

“Since implementing [the IMS], we’ve almost doubled in revenue over the past year, going from $8.5 million to an expected $15 million,” explains Annabelle Earps, Digital PR Manager. “We’re hoping to reach $25 million in sales next year.”

Even better, the new system eliminated stocking issues, which made their customers very happy. “Real-time inventory helped us achieve 4.4 on Trustpilot and 4.9 stars on Reviews.io.”

Implementations: Hard But Worth It

After so many implementations there’s one thing I keep coming back to. Operators tend to think differently about systems when they’re implemented holistically. That means change management in place before day one. It means scoping every workflow, every process, every system that touches your operation before you start, not halfway through. It means bringing your team along, not dragging them behind.

Do that, and something shifts. The system stops feeling like a disruption and starts feeling like the most reliable person on your team. You stop managing around your data and start making decisions with it.

Yes, it's disruptive. Yes, resistance is normal. But the moment it clicks, when your team stops fighting the system and starts trusting it, is closer than it feels right now.
