Most DTC brands think of their marketing budget as a number they set at the beginning of the quarter. In practice, it's set by something they rarely examine: how long their capital is locked in inventory before it turns into cash they can spend.
Taylor Holiday, CEO of Common Thread Collective, works with consumer brands doing $5M to $200M in revenue. He sees this constantly — brands trying to squeeze growth out of their ad account when the real constraint is their cost structure.
But when your COGS or fulfillment costs come down, your gross margin per unit goes up. That means you can afford to acquire customers at a higher cost and still be profitable. He discussed this in depth with Portless CEO Izzy Rosenzweig on The Modern Supply Chain:
If you would scrutinize [your cost of goods and fulfillment] with the same level that you are your Facebook ROAS, you might unlock the reality that if you could spend more on [ads] and still get to the same marginal dollar value, that's how the business might grow more.” — Taylor Holiday, CEO at Common Thread Collective
This isn't just a Portless theory. eComFuel's 2026 Trends Report, based on 300 Ecommerce owners representing $3.5B in revenue, found that brands who own their warehouses grew revenue at just 3.9%, while brands who lease or outsource fulfillment grew at 30–33%.
The report's takeaway: the operators winning today are the ones who own the least and stay the leanest. The brands growing fastest aren't the ones with the best ad creative or the highest ROAS. They're the ones whose operating structure doesn't trap their capital.
The mechanism that connects your supply chain to your marketing budget is your cash conversion cycle (CCC). This is the number of days between paying your manufacturer and receiving cash from a customer. For brands running the legacy model (bulk POs, ocean freight, domestic warehouse), that cycle is typically 60 to 90 days. Meaning everything you invest in inventory in January doesn't become spendable cash again until March or April.
Say you’re a $10M brand with a 90-day cash conversion cycle. At any given time, roughly $2.5M of your capital is locked in inventory that hasn’t sold yet. That’s $2.5M you can’t allocate to Meta, Google, or any other growth channel. Your marketing budget isn’t a strategic decision. It’s whatever’s left after your supply chain takes its cut.
Now compress that cycle to 10 days. The same $10M brand now has roughly $275K locked in inventory instead of $2.5M. The difference — over $2M in freed capital — can go directly into customer acquisition, product development, or the founder’s pocket.

This is what Taylor means when he says the scoreboard is in the financial documents. Your Facebook ROAS can be excellent and your business can still be capital-constrained if your supply chain is eating all the cash.
Taylor described a brand he worked with doing $50M in revenue with $12M in EBITDA. On paper, wildly successful. In practice, the founders had never taken a dollar out.
Every year, to fund the next 30% of growth, they had to reinvest everything into inventory. Manufacturing took two to three weeks. Ocean freight took five more. Domestic receiving and distribution added another week or two. By the time finished goods were sellable, the capital had been locked for 60 to 90 days.
“I realized that the scoreboard of business is in the financial documents. My success and failure is defined by what happens on my P&L, my balance sheet, and my cash flow statement.” — Taylor Holiday, CEO at Common Thread Collective
The brand was P&L rich and cash poor. Inventory carrying costs typically run 20 to 30% of total inventory value annually. Applied to a growing inventory base, those costs compound. The founders became desperate to sell the business because that felt like the only way to realize any value. But the offers came with onerous terms and debt that made the exit worse than they’d hoped.
This isn’t a niche story. It’s the default state for DTC brands running the legacy supply chain: profitable on the P&L, constrained by the balance sheet.
The traditional DTC supply chain has four stages that each lock capital for days or weeks. Understanding where the time goes is the first step to compressing it. For a full breakdown of each stage, see our Ecommerce supply chain management guide.
You place a PO, and your factory begins production. Capital is committed the moment the PO is placed. For many brands, this includes a deposit of 30 to 50% upfront.
Your finished goods sit in a container crossing the Pacific. During this time, your capital is literally at sea. You can’t sell, can’t fulfill, can’t generate revenue from these units.
Your 3PL receives the container, checks in inventory, distributes to shelves. More dead time before any unit is sellable.
Once inventory is live, how fast it sells depends on your marketing and demand. But the hidden costs of holding that inventory accumulate every day it sits unsold: storage fees, insurance, depreciation, and the opportunity cost of that capital.
Add it up: 8 to 12 weeks of locked capital before you see a dollar back, plus ongoing carrying costs on whatever doesn’t sell immediately. That’s the real cost of the legacy model, and it’s invisible on most dashboards.
Direct fulfillment compresses the cash conversion cycle by eliminating the two longest stages: ocean freight and domestic receiving. Instead of shipping a container to a US warehouse, finished goods move to a fulfillment center near the factory and are sellable within days of production.
Orders ship direct to customers by air, with duties applied at the parcel level as each order crosses the border. You’re not paying a lump-sum duty bill on a container of unsold inventory. You’re paying duty per order, matched against the revenue from that specific sale.
The effect on your marketing budget is direct: capital that was locked for 60 to 90 days is now locked for less than 10. That freed-up cash can go straight into customer acquisition.
Craft Club experienced exactly this. The craft kit brand was managing inventory across three warehouses, with all cash cycling back into production. After switching to direct fulfillment with Portless, they saw a 3x drop in their cash conversion cycle and 300% growth. The marketing didn’t change. The financial foundation underneath it did.
