Most ecommerce founders know cash flow is a problem. What they don’t always know is why, or how many levers they actually have to fix it.
We recently hosted a webinar with David Segal, President of Highbeam and founder of David’s Tea (which he scaled from zero to $200 million in sales before taking it public on the Nasdaq). Between his experience building a major consumer brand and our experience managing the books for hundreds of ecommerce businesses, we covered a lot of ground.
The core message: cash flow problems in ecommerce are rarely just a funding problem. They’re usually a visibility problem, an inventory problem, and a decision-making problem that eventually becomes a funding problem.
We’ll cover:
- Cash flow is the constraint, not demand
- Inventory is where cash goes to hide
- The true cost of capital (and why merchant cash advances are more expensive than you think)
- How AI is changing ecommerce finance
- When to move beyond QuickBooks (and when not to)
Let’s get into it.
Key Takeaways
- Brands can be profitable and broke at the same time. Inventory turns are everything.
- The number one way to improve cash flow isn’t a loan. It’s negotiating better buying terms with your suppliers.
- A 10% merchant cash advance fee on a four-month payback is actually a 42% APR.
- Zombie SKUs are silent cash killers. If it’s not moving, it’s money locked up on a shelf.
- AI-powered finance tools are moving from hype to genuinely useful, but only when built on the right infrastructure.
- You shouldn’t think about an ERP until you’re at $10M in revenue, and often $20M.
- Accurate financial decisions require accurate books. Everything else builds on that.
Cash Flow Is the Constraint, Not Demand
One of the first things David said in the webinar stuck with us: brands can be profitable and broke.
If you’ve felt this, you’re not alone. Our own data across hundreds of ecommerce clients backs it up. The top issues we see again and again are cash flow and working capital, cash flow forecasting and visibility, inventory and COGS tracking, and access to financing. And they’re all connected.
The root cause is almost always the same: long cash conversion cycles. You’re buying inventory months before you sell it, and every dollar tied up in product is a dollar you can’t use to grow.
David’s advice on the single best lever most founders overlook? Negotiate harder with your suppliers.
He shared a story about a profitable, nine-year-old brand doing mid-eight figures in revenue, a business by any measure that was working. But the founder was still putting 30% down at time of order, paying 60% when goods left port, and settling the remaining 10% on arrival. Effectively, he had a negative 90-day cash conversion cycle baked into every purchase order.
David’s point: if that founder could negotiate to 60-day terms by showing his track record, projecting future growth, and lining up alternative suppliers as leverage, he could free up $1-2 million in working capital without taking on a single dollar of debt.
That’s the move most brands skip because they go straight to looking for a loan. Pull every lever you have before you borrow.
Other levers worth considering: using credit cards strategically, optimizing inventory ordering, and making sure idle cash is actually working for you.
Inventory Is Where Cash Goes to Hide
If cash flow is the symptom, inventory is usually the disease.
What we see constantly: brands that don’t have a clear picture of their inventory end up making bad buying decisions, carrying too much of the wrong product, and running out of the right one. That creates a cash spiral that’s hard to unwind.
David described what world-class inventory management looks like: it starts with an open-to-buy. Before you place a single order, you know exactly how much you can afford to spend, based on your current inventory position, sales velocity, months of stock on hand, and what’s becoming stale.
Without that number, you’re shopping blind.
A few things we emphasized in the webinar:
Zombie SKUs are a real problem. In a multi-SKU business, it’s easy to let slow-moving products sit on the shelf indefinitely. But that’s not just dead inventory. It’s dead cash. Every unit that isn’t moving is capital that could be funding your fastest-growing SKUs instead.
Q4 is a trap for brands that don’t manage inventory actively. As David noted, if you cut ad spend to improve margin during peak season but don’t sell through your inventory, you can end the season with more stock than you planned and far less cash, right when bills are due.
Inventory tracking is an operational problem, not just a financial one. At LedgerGurus, we go deeper on inventory than most fractional accounting firms because we have to. Bad inventory data creates bad financial data. And bad financial data creates bad decisions. The discipline has to be built at the operational level, covering how you receive goods, handle returns, and track samples sent to influencers, before it can show up accurately in your books.
The True Cost of Capital
Here’s the part of the webinar that generated the most reaction, and for good reason.
Merchant cash advances are not what they appear to be.
When a lender quotes you a “10% fee,” most founders hear 10% and think it’s comparable to a 10% interest rate. It isn’t, not even close. Here’s why: the fee is flat and constant, but you’re paying back principal with every draw from your sales. Your balance goes down. Your fee stays the same. And you’re usually paying it back in months, not a year.
A 10% fee on a four-month payback period works out to a 42% APR.
We’ve seen brands get into serious trouble this way, not because they made a bad business decision, but because they didn’t understand what they were actually agreeing to. The math was never explained clearly.
David’s team at Highbeam built a calculator specifically for this. You plug in your flat fee and payback period and it shows you the equivalent APR, what you’d pay with a true line of credit, and what you’d save. Worth running your current loan through it if you have one.
A few things to look for when evaluating any lending product:
- Is the rate expressed as a true APR?
- Are there prepayment penalties? (With merchant cash advances, paying back faster actually makes the effective rate worse, not better)
- Are there origination fees or fixed charges on top of the rate?
- Can you only pay for what you use, or are you locked into a fixed payment schedule?
Easy money is almost always expensive money. The extra friction involved in getting a true line of credit is worth it.
How AI Is Changing Ecommerce Finance
AI came up a lot in the second half of the webinar, and David had some of the most grounded takes we’ve heard on it.
The honest version of where things stand: most founders who have tried dumping their financial data into a general AI tool have had mixed results. The responses can be inconsistent. It’s expensive when you’re using a powerful model for basic queries. And it’s hard to audit. You often can’t trace how the AI got to its answer, which matters a lot when you’re making financial decisions.
What actually works, based on what Highbeam has built with their new AI engine Luma: purpose-built AI trained on your specific domain, with repeatable workflows and an auditable output.
Luma connects to QuickBooks, NetSuite, your banking, cards, and inventory data. Rather than generating a one-off answer each time, it writes code when it executes a query, so the same process can run again reliably on Monday and Friday. Every update is tracked: who made it and when. You can see how it built its forecast, what confidence interval it used, and whether it back-tested.
That’s a fundamentally different product than pasting your P&L into Claude and asking it what’s wrong.
David used an analogy we liked: you can make your own ice cream, but most people shouldn’t. The artisanal shop on the corner that’s spent years perfecting the recipe will produce something better for $3 a cone than most people will produce in their own kitchen after hours of effort and hundreds of dollars in equipment.
For most ecommerce brands, the right move with AI right now is: pick one painful workflow, find a purpose-built tool that handles it well, prove the value, then expand. Don’t try to boil the ocean.
When to Move Beyond QuickBooks, And When Not To
We got several questions in the webinar about inventory management systems and ERPs, and this is an area where we have strong opinions built from experience.
QuickBooks Online inventory management is not built for ecommerce. It lacks the depth of capabilities, multi-channel integrations, and real-time tracking that product-based businesses need. We’ve worked with Intuit on this, and they’re investing in it, but it’s not there yet. If you’re managing inventory in QBO, you’re likely working around its limitations rather than with them.
Dedicated inventory management systems, tools like Finale or Katana, are designed for this. They handle multi-channel sync, landed cost allocation, returns categorization, and real-time quantities in ways QBO simply doesn’t.
As for NetSuite and other ERPs: wait. This is advice we give constantly and it doesn’t change. ERPs are expensive to implement (often tens of thousands, sometimes hundreds of thousands of dollars), expensive to operate, and require dedicated expertise to maintain. They’re built for complexity, which means usability suffers. Three clicks in QuickBooks can become twenty clicks in NetSuite.
Our rule of thumb: don’t consider an ERP until you’re at $10 million in revenue, and often $20 million. The flexibility and speed you get from best-of-breed systems will serve most brands better for longer than you’d expect. The longer you can stay nimble, the more energy you can put into actually growing.
The Bottom Line
Cash flow problems in ecommerce almost always come back to the same root causes: not enough visibility into inventory, not enough clarity on the true cost of capital, and financial data that isn’t clean enough to make good decisions from.
The brands that do this well aren’t necessarily the ones with the most funding. They’re the ones who know their numbers, turn their inventory consistently, and make financing decisions with eyes open.
That’s exactly what we help ecommerce brands do at LedgerGurus. Here’s an example with one of our clients.
