Most founders track revenue. Some track margin. But the number that actually tells you whether your business can keep growing? Undoubtedly the cash conversion cycle.
And if you're running a product business, it's probably the most important metric you're not watching closely enough.
Here's the short version: it measures how long your cash is trapped inside your business before it comes back to you. Every day you pay a supplier before a customer pays you, that money is stuck. It's not lost, but it's not available either. And the longer that gap runs, the harder it becomes to take on new orders, launch new products, or do anything that requires cash you don't currently have sitting in your account.
This guide breaks down exactly what the cash conversion cycle is, how to calculate it, what a good number looks like for product brands, and – most usefully – what you can actually do to improve it.
💡 Key takeaways
The cash conversion cycle (CCC) measures how long your cash is tied up between paying suppliers and getting paid by customers
It's calculated as: Inventory Days + DSO − DPO
For product brands, a CCC of 30–60 days is healthy; 90–150 days is common; anything beyond that is worth addressing
Shortening your CCC frees up cash without needing to raise more of it
There are three main levers: move inventory faster, get paid sooner, pay suppliers later
What the cash conversion cycle actually is
The cash conversion cycle tells you one thing: how many days your cash is locked up in your operating cycle before it comes back.
Every product business goes through the same loop. You pay a supplier. You wait for goods to arrive. You hold inventory until it sells. You issue an invoice. You wait for the customer to pay. Only then does the cash return.
The CCC measures the total time of that loop, from the moment cash leaves your account to the moment it comes back. A shorter cycle means your cash is working harder. A longer one means more of it is sitting idle – tied up in stock, in transit, or in unpaid invoices – while you're trying to fund the next order.
It's a simple concept. But for product businesses, where you're often juggling 60-day production runs, 30-day shipping windows, and 60–90 day retailer payment terms all at once, it's anything but simple to manage.
How to calculate it
The cash conversion cycle is made up of three components.
Inventory days measures how long products sit in stock before they're sold. The formula is:
Inventory Days = (Average Inventory ÷ Cost of Goods Sold) × 365
A high number here means stock is moving slowly – and capital is sitting in a warehouse rather than working for you.
DSO (Days Sales Outstanding) measures how long it takes to collect payment after a sale. The formula is:
DSO = (Accounts Receivable ÷ Revenue) × 365
High DSO usually means slow-paying retailers or distributors. Cash is stuck in invoices that technically exist but haven't landed in your account yet.
DPO (Days Payable Outstanding) measures how long you take to pay your suppliers. The formula is:
DPO = (Accounts Payable ÷ Cost of Goods Sold) × 365
Unlike the other two, a higher DPO is generally a good thing – it means you're holding onto cash longer before it goes out.
Put them together and you get:
Cash Conversion Cycle = Inventory Days + DSO − DPO
If your inventory sits for 60 days, customers take 75 days to pay, and you pay suppliers in 30 days, your CCC is 105 days. That's 105 days of cash locked inside your business on every cycle.
What a good CCC looks like for product brands
There's no universal "right" number – it varies a lot by industry, business model, and how you sell. But as a rough guide:
Under 30 days is excellent, and rare for inventory-heavy businesses
30–60 days is healthy and gives you room to grow
60–90 days is common and manageable, especially if you have financing in place
90–150 days is where things get expensive – every order requires a lot of capital tied up for a long time
150+ days creates serious growth constraints unless you have a financing strategy built around it
For brands sourcing internationally, selling through retailers, or operating in seasonal categories, a cycle of 90–120 days isn't unusual. The goal isn't necessarily to hit 30 days – it's to understand your cycle clearly enough to plan around it, and to have a strategy for closing the gap when it matters.
Why a long cycle is such a problem for growing businesses
Here's the thing about a long cash conversion cycle: it doesn't just affect your cash flow today. It compounds as you grow.
When your business is small, the cash tied up in one cycle is manageable. But as your order sizes increase, that same cycle ties up a proportionally larger amount of capital. A brand doing $500k in revenue has cash gaps they can often manage on the fly. A brand doing $5 million has cash gaps that require a real strategy.
This is why so many founders hit a wall at a certain point – not because their business isn't working, but because their working capital structure hasn't kept up with their growth. The demand is there. The orders are coming in. But the cash to fulfil them is still sitting in last month's inventory or waiting on a retailer who pays in 90 days.
A long cycle also limits your ability to say yes to the opportunities that actually accelerate growth: the big retail listing, the bulk production run that halves your unit cost, the new market launch. When cash is tied up for 120 days at a time, you need a lot of it in reserve before you can move.
How to shorten your cash conversion cycle
You've got three levers. Pull all three if you can.
Move inventory faster. Better demand forecasting, leaner SKU counts, and faster sell-through all reduce inventory days. Every day you can shave off is cash that becomes available sooner. This is partly operational and partly about being ruthless with which products you actually stock deeply.
Get paid sooner. If your DSO is high, start with the basics: are invoices going out immediately after delivery? Are payment terms clearly communicated? Do you chase overdue payments consistently? Early payment discounts (offering a small reduction for payment within 10 days, for example) can shift the economics for some customers. And for brands with strong wholesale or retail order books, invoice financing is worth understanding – it lets you unlock cash from outstanding invoices before they're due, without waiting on the customer.
Pay suppliers later. Extending DPO is one of the highest-leverage things you can do for your working capital position. If you're currently paying suppliers in 30 days, getting that to 60 or 90 can make a meaningful difference – especially on large production runs. This is often easier to negotiate than founders expect, particularly as order volumes grow. And for brands that need to pay suppliers upfront before production even starts, inventory financing effectively gives you extended payment terms without needing to renegotiate with the supplier directly.
The biggest mistake is treating these as separate problems. DSO is a finance issue. Inventory days is an ops issue. DPO is a procurement issue. In reality, they're all part of the same cycle – and improving all three compounds quickly.
Treyd, working capital for product brands, can help you with all three.
A real-world example
A growing apparel brand places a production order in January. Here's how the cycle plays out:
Day 0: 40% supplier deposit paid to start production
Day 60: Production complete, goods shipped
Day 90: Goods arrive and are delivered to retail partners
Day 150: Retailer pays on 60-day terms
That's a CCC of roughly 150 days. For every £100,000 order, that brand needs £100,000 of working capital tied up for five months before it comes back.
Now suppose the brand works on DPO – using inventory financing so the supplier deposit is effectively extended to 90 days. They also tighten their invoicing process and get retailers paying in 45 days instead of 60. The new cycle drops to around 105 days.
That's 45 days of capital freed up. On a £500,000 production run, that's meaningful money available for the next order, a new market launch, or just breathing room.
The numbers matter. And once you know yours, you can start working on them.
Summary
The cash conversion cycle is one of the clearest pictures of how efficiently your business uses cash. A long cycle doesn't mean your business is failing – but it does mean more of your capital is tied up at any given time, which limits how fast you can grow and how much risk you can absorb.
The formula is simple: Inventory Days + DSO − DPO. The work is in moving each number in the right direction, consistently, over time.
Founders who understand their CCC early tend to make smarter decisions about inventory, payment terms, and when to use financing. Those who wait until they hit a cash wall often find themselves solving an urgent problem with expensive options.
