Profit Meets Planning: Smarter Inventory Management
Profit is a goal for any business. At a minimum, it allows them to keep the doors open. I know that for me, for years, I focused on profit as something that came from the sales and pricing portion of business. But profit really derives from the foundational aspects of our businesses, like value-added services, relationship management, and efficient operations. And a part of efficient operations that gets overlooked is inventory management.
Inventory management isn’t just about stocking shelves or tracking what’s in your bins. It’s the heartbeat of your cash flow, customer experience, and stress level. I’ve seen too many shops treat inventory as an afterthought. They either have boxes of forgotten blanks piled up, dust-covered “samples” collecting “someday” projects, and cash tied up in stuff that isn’t selling. On the other side of the coin, expensive rush fees and overnight shipping, missed deadlines, and constant scrapping of the bottom of the barrel to service their customers.
Your Inventory Tells a Story
Inventory isn’t just physical goods. It’s a reflection of how well your business is designed. Every item sitting on your shelf represents a decision made, or avoided, somewhere along the way. Did you buy too much because you wanted to hit a supplier discount? Did you fail to set customer order deadlines, so jobs keep trickling in unpredictably? Or maybe your team keeps running out of popular sizes because no one’s tracking reorder points. Each one of those decisions costs money.
I worked with a decorator who prided himself on never saying no to an order. He’d buy whatever blanks his customers wanted, even for one-off projects. His inventory ended up having one of every color, size, and brand. But when we ran the numbers, he was sitting on thousands of dollars of idle product.
He wasn’t managing inventory … he was collecting it.
Once he started designing policies around what made sense for his business, not just what customers asked for in the moment, he freed up cash, space, and peace of mind.
Start by tightening the link between your sales process and your purchasing habits. Too often, decorators treat these as separate worlds. The sales team promises quick turnaround, the production team panics, and purchasing scrambles to find stock at rush prices. This constant reaction mode eats profit.
Instead, build your system to predict needs before they happen. That means collecting data from your busiest months, understanding your top-selling SKUs, and setting reorder points that reflect reality. A spreadsheet, a Google Sheet, or even a whiteboard can be enough if it’s used consistently.
The magic word here is “system,” not “memory.” Not, “I think we have some of those.” Systems create stability. A simple one I like is based on the Pareto Principle (the 80/20 rule). Track which 20% of your products account for 80% of your sales, and make sure those never hit zero. Then, have a plan for how to liquidate or repurpose slow movers before they become dead weight. To me, anything that sits in your inventory for six months or more is dead weight, and in my system, it's worth getting any value you can out of those products to free up space and clutter. I suggest things like offering bundles, running limited-time sales, or converting older blanks into samples or test prints.
Set Expectations Early and Often
But systems don’t stop at spreadsheets or inventory management and purchasing tools. They extend into your customer policies. Clear expectations protect your profit more than any sale ever will.
Set clear ordering windows, establish minimums for custom orders, and communicate turnaround times early. When your customers understand your process, they plan accordingly, and you stop firefighting every job. Early in my entrepreneurial career, I was selling supplies for the prepress portions of the screen-printing process. I would buy the product from a manufacturer, then provide value-added services like education and support.
I wanted to focus on customer service, and at the time, I thought that meant saying yes to everything. Someone would call up and need an ink cartridge, I would say yes, then order the minimum required amount, ship the one, and then inventory the rest, believing people would flock to me to buy the rest of the inventory.
That was an expensive lesson to learn, as throwing out old expired ink cartridges was a tough pill to swallow. What I could have done is set a policy that special order items required a minimum purchase amount, done more research into the demand for the product, or even said no and protected my business. The most important thing I could have done is to align my ordering cycle with customer behavior. That is better customer service. Teach your customers what to expect and then help them also manage their inventory, all while making sure you deliver on your part of the promise.

Design an Experience, Not Just a System
If you really want to optimize inventory, stop thinking like a printer and start thinking like a designer. You’re designing experiences, not just products. When you create a buying process that feels reliable and professional, customers notice. They’ll wait a day longer or pay a bit more because you make it easy. That’s profit through planning.
I also recommend separating your inventory into three zones:
- Working stock
- Growth stock
- Risk stock
Working stock covers your most common blanks and supplies. Growth stock is where you experiment with new products or styles, but only in limited quantities. Risk stock is anything that hasn’t moved in six months, as I mentioned previously, and it either gets discounted, donated, or recycled. That simple classification helps you make smarter decisions without getting lost in the weeds.
Technology can help, but it’s not the solution by itself. I’ve seen shops buy expensive software that ends up collecting digital dust because no one uses it. The best inventory system is the one that actually fits your rhythm. Whether it’s QuickBooks, Odoo, easily accessible spreadsheets, or color-coded shelves, consistency beats complexity every time.
If you’ve ever struggled with slow cash flow, chances are your inventory is part of the problem. Each shirt, roll of vinyl, or bucket of plastisol ties up money that can’t work for you until it sells. That’s why having a reliable reorder process is a superpower. Set minimums, track turns, and know exactly how long it takes to replenish key items. When you stop guessing, your cash flow starts breathing again.
Another overlooked piece is vendor relationships. Treat your suppliers like partners, not vending machines. The best vendors help you forecast demand, alert you to potential delays, and even hold inventory for you if they trust your consistency. Communication here can save thousands. A quick call before peak season to confirm timelines and stock levels goes a long way toward avoiding headaches.
Profit Comes from Predictability
I tell business owners this all the time: Your systems are either serving you or silently draining you. If your shelves are full but your bank account isn’t, that’s a clue. Build your policies around what protects your time, cash, and sanity. Create clear expectations for customers, structured ordering habits for your team, and simple tools to track what’s really happening.
Profit isn’t about luck or working harder. It’s about building predictability into your process. When planning meets intention, profit naturally follows. Inventory management just happens to be one of the clearest places to see that truth in action.
