How Raw Materials, WIP, and Finished Goods Tie Up Cash
“We’re making money, so why do I feel broke?”
That’s the question I hear most often when a Founder reaches out for help. They’ve got strong revenue, and margins look healthy. But the cash just isn’t there. It’s frustrating and, honestly, pretty common.
I’ve learned the culprit is usually inventory. It’s not just finished goods collecting dust in a warehouse but cash getting trapped at every stage of the inventory life cycle. Cash gets swallowed by work-in-progress (WIP) and quietly frozen in raw materials. If you don’t have full visibility into how your inventory moves, you can’t manage your liquidity no matter how many units you sell.
At Cultivar, we help Founders pinpoint exactly where cash is hiding in their operations. Once you know where your dollars are stuck, you can start unlocking them without jeopardizing production. Let’s walk through what that looks like at every stage.
Raw Materials: Where the Cash Drain Begins
The cash drain begins with raw materials because Founders often stockpile inventory to hit vendor minimums long before revenue appears. I’ve seen Founders buy bottles, labels, ingredients, and custom pouches months ahead of schedule to take advantage of bulk discounts or avoid last-minute production panic. The logic makes sense, but that strategy quietly siphons off liquidity.
Consider an example of the Founder of a sparkling water brand I worked with. She ordered a full quarter’s worth of shrink-wrapped cans in anticipation of a big wholesale launch. But the retail partner delayed onboarding by 6 weeks. Those cans sat in a storage unit, and her cash was locked in aluminum instead of fueling growth.
It’s the same story in the wine world. I’ve worked with wineries that bought custom glass far in advance, only to delay bottling due to harvest timing or label revisions. That up-front spend means capital is tied up just sitting on a pallet.
Here’s the kicker: Raw materials live on your balance sheet as an asset, but they don’t generate cash until they’re converted into sellable goods. If you overbuy or mistime purchases, your liquidity takes a hit even if your margins look great on paper.
To manage this better:
Forecast your production demand with realistic lead times.
Push vendors for more flexible MOQs or staggered deliveries.
Track inventory turns on raw materials and flag anything sitting longer than 60-90 days.
The goal is to align purchases with actual demand rather than wishful thinking.
WIP: The Invisible Inventory Holding Up Your Cash
Work-in-progress (WIP) holds up your cash by trapping dollars in production batches, fermentation tanks, or co-packer queues where it can't be sold yet. Unlike raw materials or finished goods, WIP is harder to see, but it ties up cash all the same.
I worked with a snack bar company that had a four-step process across three vendors. Dough was mixed at one facility, cut and baked at another, and shipped to a third site for packaging and labeling. Each handoff added delays. Meanwhile, their cash was stuck in half-completed bars that couldn’t be sold.
Wineries feel this pain acutely. Grapes are crushed, fermented, aged, and bottled over a span of months or even years. All that time, your dollars are tied up in tanks, barrels, and aging stock.
Here’s where many Founders get caught. They don’t account for how long it takes to turn materials into money. That lag, the cash conversion cycle, can stretch much longer than expected when WIP isn’t moving efficiently.
Signs you’ve got WIP trouble include:
Long lag times between production stages
Inventory that's technically in progress but stalled due to bottlenecks
Lack of real-time visibility into where batches are or what’s delayed
What helps is tightening production schedules and adding visibility tools. I’ve helped clients implement simple dashboards that show where every SKU is in the production process. That transparency helps flag where cash is being held hostage.
Finished Goods: When Inventory Looks Good but Acts Like a Liability
Finished goods act like a liability when they sit on shelves collecting dust instead of converting into immediate revenue. This is where most Founders feel safest because the product is done, boxed, labeled, and ready to go. It feels like progress, but unless those goods are selling quickly, you just have money sitting on shelves.
One winery I worked with had a beautiful vintage bottled and labeled for direct-to-consumer sales. But their email list wasn’t primed, the campaign wasn’t ready, and the wine sat in storage for 3 months. They weren’t selling. They were just spending on warehousing.
The same goes for CPG brands that overshoot demand. A granola brand I advised produced a full run for a national retailer, only to find out their shelf placement had been delayed by 2 months. They had pallets of finished goods but no PO in sight.
Finished goods tie up more than just cash. They can lead to:
Spoilage or expired shelf life.
Dead stock that requires disposal.
Forced markdowns or distributor discounts to clear aging inventory.
You might see finished goods as an asset on the books, but if they aren’t moving, they’re a liability in disguise. The longer they sit, the less valuable they become. To keep this in check, track days inventory outstanding (DIO) and aim to lower it over time.
Why Is Inventory-Integrated Accounting So Difficult?
Inventory-integrated accounting is difficult because it requires reconciling data across disconnected platforms like Shopify, Amazon, and wholesale portals. In my experience, this is the specific pain point that keeps Founders up at night.
You’re trying to match sales data from your Shopify store with inventory deductions in your warehouse management system, all while Amazon is reporting different numbers for FBA stock. If these systems don’t talk to each other perfectly, you end up with ghost inventory where your accounting software thinks you have products that physically don’t exist.
This leads to incorrect COGS (Cost of Goods Sold) calculations, which messes up your gross margin reporting. Worse, it creates a lack of trust in your own numbers. At Cultivar, we spend a lot of time untangling these webs to ensure that what’s on the books matches what’s in the warehouse.
Strategies to Improve Liquidity Without Sacrificing Inventory
You can improve liquidity without sacrificing inventory by tightening your production schedule and syncing your purchasing to actual demand. You don’t need to gut your production plan to free up cash. You just need to make inventory more efficient.
Here are some of the most effective tactics we recommend to clients:
Demand-based purchasing: Buy raw materials closer to actual sales needs. Build vendor relationships that allow smaller runs or delayed shipments.
Tighter production scheduling: Map out production to avoid idle time and bottlenecks. This keeps WIP from dragging on and speeds up your cash cycle.
Just-in-time (JIT) manufacturing: For brands with predictable demand or strong co-packer partnerships, JIT reduces raw and WIP inventory without risking stockouts.
SKU rationalization: More SKUs mean more complexity and more frozen capital. We helped one beverage brand cut its SKUs by 30% and see a 22% lift in inventory turns.
Every Founder I’ve worked with has had some version of a blind spot when it comes to how inventory affects their cash. What matters is finding it, quantifying it, and creating a plan to fix it.
Inventory Is the Key to Cash, and Cultivar Can Help You Unlock It
Every ingredient you buy, every bar you half-produce, every finished bottle you store is either helping or hurting your ability to grow. If you’re selling but still scrambling for cash, chances are your inventory is part of the problem. The good news is that once you know where your dollars are getting stuck, you can start freeing them up without sacrificing your production goals or growth plans.
At Cultivar, we help CPG Founders and winery owners understand how to make inventory a tool for liquidity, not a drain. And it starts with visibility.

Excess Inventory CPG Brand FAQs
What Are the Signs That My Inventory Management Systems Are No Longer Scaling?
The clearest signs that your systems are no longer scaling are frequent stockouts despite having inventory on hand, selling products you don't actually have (overselling), and spending hours manually reconciling spreadsheets at the end of the month. If you can’t get a real-time view of your inventory value across all sales channels without logging into three different platforms, your system is broken.
What Is the Difference Between Raw Materials and WIP?
Raw materials are the basic inputs you haven't touched yet, like glass bottles, flour, or labels sitting in storage. Work-in-progress (WIP) represents inventory that has entered the production process but isn't a finished product yet, such as wine fermenting in a barrel or granola currently in the oven. Both tie up cash, but WIP is harder to liquidate if you need quick funds.
How Often Should a CPG Founder Review Inventory Reports?
A CPG Founder should review inventory reports at least weekly to catch slow-moving items before they become dead stock. While your finance team might look at the official numbers monthly to close the books, operational leaders need a weekly pulse on velocity and days inventory outstanding (DIO) to adjust production schedules in real time.
