We Were Running Our Business on Spreadsheets and Prayers: What Customer Transformations Actually Look Like

It’s month end, and you’re popping antacids and pain relievers because your inventory numbers aren’t adding up.

Again.

You’ve been running your growing product business on a collection of spreadsheets, a few heartfelt prayers, and gut instinct for so long that inaccurate stock levels and distrust of your numbers have become the uncomfortable norm. Still, you cross your fingers each month, hoping that everything somehow, some way matches up this time round without the need for hours of manual reconciliation.

It won’t.

How do I know? Because I’ve participated in dozens of implementations, and businesses that once relied on simple spreadsheets all tell me the same thing: We could never trust our numbers.

The constant adding to and editing of multiple, fragmented spreadsheets by various team members? It always leads to inconsistencies and questions.

But here’s the good news: You don’t have to operate this way. In fact, you shouldn’t.

Inventory accuracy is not just an operational improvement. It’s a competitive moat. Keeping your competitors out while becoming a business that transitions from being reactive to proactive changes everything.

Let me show you how.

The Before State

I’ve seen tons of fragmented operations. They struggle with inventory that’s consistently off. Decisions are made instinctually rather than based on data. And teams are spending hours reconciling numbers instead of running the business.

They’re not alone.

Cin7’s 2025 State of Inventory Intelligence Report found that product businesses spend 16 hours a week syncing inventory across disconnected systems and channels. That's 104 workdays a year, and $21,632 annually per entry-level employee, just keeping fragmented systems from falling apart. Ironically, 73% of these businesses are trying to grow.

That’s a lot of time and money wasted. One company that knows about this loss firsthand is Changing Habits. An Australian-based organic health food brand, Changing Habits was acquired in 2024, and the new team acquired a broken, stress-inducing tech stack.

Stock on hand valuations were so far off that their external accounting firm stopped trusting the financial data flowing into Xero. Nobody could plan around lead times of three to six months, because nobody could say with confidence what was actually in stock. Stockouts became routine. Eventually, someone had to drive to the offsite warehouse and count inventory by hand, because the numbers in the system couldn't be trusted.

“Making sense of data was really difficult,” says owner Sergio Zambrano.

It's the fragmented systems problem, showing up the way it always does. Our report found that 40% of businesses are struggling to scale, and 42% point to unintegrated inventory and e-commerce platforms as one of the reasons why. Disconnected systems don't just create stockouts and overstocking. They create inventory blindness, and inventory blindness turns into late nights, frustrated customers, and owners who don't sleep well because they don't trust their own numbers.

There's a way out of that.

The Transition

So you're staring down the decision. Keep patching the spreadsheets together, or go through an implementation.

Neither option is comfortable. Stick with the old way, and you already know what you're signing up for: the same inventory headaches, the same acid reflux, indefinitely. Move forward, and you're signing up for something harder in the short term. An implementation takes real work. It takes patience. And somewhere in the middle of it, your team is going to push back.

That resistance is normal. Your team knows the current process is broken, but at least it's a broken process they understand. Change means stepping into the unknown, and that's a real fear, not a minor inconvenience. Your job isn't to eliminate that resistance. It's to walk your team through it, and to be honest about what's on the other side.

Because there is something on the other side. I've watched it happen enough times to know it's not luck. The businesses that make it through the resistance land somewhere better than where they started, and it's not close.

Here's what that actually looks like.

The After State

What do all these companies that opted to forgo their spreadsheets in favor of a connected inventory system have in common?

More efficiency. Faster (and better) decisions. Confident supplier conversations. Channel expansion that would have been impossible before. A team that trusts its data.

None of these benefits would see the light of day without the right IMS connecting inventory, supplier, warehouse, and sales channel data into one, real-time system.

For Changing Habits, team member Tessa Pennick used to drive out to the warehouse every week to manually verify stock because the system numbers couldn't be trusted. She doesn't do that anymore. "Our numbers are all adding up," says CMO Sonya Keenan, and that sentence means more than it sounds like it should if you've never had to say the opposite out loud.

HairCo's shift was less about trust and more about what trust unlocked. Once the team could actually rely on their inventory data, Cin7's ForesightAI gave them something they never had before: real answers to how much to order, when, and where to store it. That turned into a 10% increase in sales, but the number I'd point to isn't the sales lift. It's that they stopped losing sleep over inventory they couldn't see.

I've watched this play out the same way for businesses in completely different industries. GoNano freed up enough time from manual data entry to actually invest in R&D instead of just keeping up. Workplace Depot went from struggling to track basic customer and inventory data to a 4.4 on Trustpilot. Different starting points, same shift: the moment a business stops fighting its own systems, it finally has room to grow.

That's the part spreadsheets can never give you. Not more data. Room.

Where Do You and Your Product Business Go From Here?

Here's the part I want you to sit with. Growth doesn't wait for you to be ready.

I've watched brands get offered their biggest deal yet, a major retail partner (think Costco, Walmart, Target, etc.), a wholesale account that would double their volume, and say no. Not because the opportunity was wrong. Because they knew what their operation was actually built on, and they knew it wouldn't hold.

That's the real cost of spreadsheets and prayers. It's not just the wasted hours or the reconciliation headaches. It's the growth you turn away because you can't trust your own numbers enough to take the risk.

You don't have to find out the hard way. Every business in this piece was once exactly where you might be right now, patching things together and hoping it holds. None of them got to where they are by waiting for the perfect moment. They just stopped tolerating the old way, one decision at a time.
