If you run a service business and you're doing somewhere between $1M and $3.5M in revenue, there's a good chance you've been in this position: you land a solid contract, you have strong customers who pay on time, and yet every time you go to a lender, the offer you get back doesn't come close to reflecting how solid your business actually is.

That gap is almost never about the quality of your business. It is almost always about how your capital is structured — or more accurately, how it is not structured at all.

Recently, Michael Intrator, CEO of CoreWeave, explained on the All-In Podcast how his company raised roughly $35 billion in 18 months to build GPU infrastructure for some of the largest tech companies in the world. The headline number is impressive. But what actually caught our attention at Bayside was the structure he described — something he calls "the box" — and the fact that the same logic behind it applies to service businesses a fraction of that size.

What Is Purchase Order Financing and Contract-Based Funding for Small Businesses?

Before we break down the CoreWeave strategy, it helps to understand the funding tools that mirror it at the small business level. Purchase order financing is a type of funding where a lender advances capital based on a confirmed order or contract from a creditworthy customer — meaning the lender is primarily underwriting your customer's ability to pay, not just your business credit or tax returns. Contract-based facilities work similarly: the lender looks at the strength and terms of your existing contracts to determine how much capital you can access. Both tools allow a growing service business in Miami, Fort Lauderdale, or West Palm to leverage the quality of their customer relationships rather than being penalized for being early-stage or asset-light.

What the CoreWeave Box Strategy Actually Is

Here is how Intrator describes it: when a major enterprise customer like Microsoft wants to buy GPU compute, CoreWeave signs a multi-year contract with them. CoreWeave then takes that contract, the GPUs they purchased from Nvidia, and the data center agreement, and puts all of it into a separate, self-contained structure — the box.

Microsoft does not pay CoreWeave directly. The cash flows into the box first. The box then pays the data center, power, interest, and principal to lenders in that order. Only after all of those obligations are covered does any money flow back to CoreWeave. Lenders are not underwriting CoreWeave the company in isolation. They are underwriting the cash flows and collateral inside that specific box — which includes the strength of Microsoft as the paying customer. That distinction is the entire point.

"Lenders are not underwriting your company. They are underwriting the cash flow inside the box — which includes the strength of your customer." That is the insight that changes everything, whether you are a $35 billion GPU company or a $2M service business in South Florida.

What This Means for a Service Business Doing $500K to $5M

Here is a scenario we see often at Bayside. A service business owner in Miami is doing around $3M in annual revenue. She lands what looks like a dream contract with a well-known local institution. Big name, impressive revenue on paper. The margins are thin, the scope is demanding, and the payment terms are net-60. At the same time, she has three smaller, recurring contracts with steady clients who pay clean net-30 and have solid margins.

Before working with Bayside, she borrowed heavily against a generic line of credit, stacked a short-term merchant cash advance to cover a cash flow gap, and pledged essentially her entire business to make one contract work. Her DSCR — the ratio banks use to assess loan capacity — looked terrible on paper even though her actual customers were excellent.

After we worked through her contracts together, we restructured around a contract-backed facility tied to her three reliable clients. The facility was underwritten on their payment history and credit strength, not her tax returns. She accessed nearly twice the capital at a rate roughly 40% lower than the MCA she had been renewing. And her SBA borrowing profile was clean and open for when she needed it.

What we work toward with owners at Bayside is a version of what CoreWeave is doing, scaled to their reality. The three things we focus on are: First, put your best contracts in the box — which of your customers actually pay on time, have clean terms, and have enough margin to support both the cost of the work and any funding tied to it? Second, use funding tools that lean on your customer paper, not just you personally — at the $500k to $5M range, that often means purchase-order or contract-backed facilities, AR lines, or other structures where the lender is primarily underwriting your customer's ability to pay rather than just your FICO score and tax returns. Third, keep each deal ring-fenced — do not pledge your entire business to every risky contract. If one deal underperforms, the rest of your company should be protected.

Which Funding Tool Is R

Not all funding tools are created equal, and using the wrong one at the wrong time can either lock you out of better options or cost you significantly more than necessary. Here is a plain-English breakdown of the most common tools available to service businesses in South Florida at the $500k to $5M range:

Purchase Order Financing: Best for businesses with a confirmed order or contract from a creditworthy customer. The lender underwrites your customer's ability to pay, not just your business. Typical range: $50K to $5M. Rates typically 1.5% to 5% per month on the advance.

Contract-Based Facility: Best for government contractors, professional services, and any business with multi-year or recurring contract revenue. The lender underwrites the contract itself. Typical range: $100K to $2M. Terms often match the contract duration.

Accounts Receivable (AR) Line of Credit: Best for businesses with consistent invoicing and reliable payers. Lender advances a percentage of outstanding invoices (typically 80% to 90%). Revolving facility that grows with your receivables. This is often the cleanest tool for a scaling service business.

SBA 7(a) Loan: Best for long-term capital needs — equipment, working capital, acquisition. Lower rates and longer terms than all of the above, but requires clean financials, structured debt, and a strong DSCR. This is the goal state that the tools above should be building toward.

MCA (Merchant Cash Advance): Fastest to access, highest cost. Rates equivalent to 40% to 150% APR are common. Fine for a true bridge in an emergency, but using this as ongoing capital is one of the most common ways we see South Florida businesses damage their bank and SBA options. Avoid if there is any alternative.

How the Wrong Structure Damages Your Future Bank and SBA Options

Banks and SBA lenders do not just look at your revenue. They look at how your existing debt is structured, how clean your cash flow coverage is, and how concentrated your risk is. When everything is jumbled together — MCAs stacked on lines of credit, short-term advances funding long-term work, no clear connection between cash flow and obligation — even a strong business can look risky on paper.

Here is what most owners never hear clearly: the capital decisions you make today do not just affect cash flow this quarter. They shape what a bank or SBA lender sees when you go to them for lower-cost, longer-term money 12 to 24 months from now. A well-structured box now keeps that door open. A messy, reactive stack now can close it. We see this play out regularly with South Florida business owners who have genuinely strong businesses but cannot access SBA or conventional bank financing because their balance sheet looks like a patchwork of short-term debt.

The specific things SBA and bank underwriters will flag: a debt service coverage ratio (DSCR) below 1.25x, high concentration of MCA or short-term debt relative to revenue, inconsistent cash flow patterns that suggest reactive borrowing, and multiple positions from alternative lenders that raise questions about financial management. All of these can be corrected — but it takes time and a clear plan to work backward from them.

How Bayside Helps You Build Your Box in South Florida

Most owners running a service business in Miami, Fort Lauderdale, or West Palm are busy running their business. They are not capital engineers, and they should not have to be. That is what we are here for at Bayside.

When we work with a service business owner, we look at where your real boxes already are. Which of your contracts and customer relationships are genuinely box-worthy? Which funding tools available at your size actually match that structure? And what does the path forward look like so that today's capital decisions do not damage tomorrow's bank or SBA options?

If your customers are strong but your funding offers do not reflect that reality, or if you are looking at a new contract or offer and are not sure whether it belongs in your box, we would be glad to take a look.

Frequently Asked Questions About Business Funding in South Florida

What is purchase order financing and how does it work for service businesses? Purchase order financing is a type of funding where a lender advances capital based on a confirmed order or contract from a creditworthy customer. Instead of underwriting your business in isolation, the lender primarily looks at your customer's ability to pay. At the $500k to $5M range, this is one of the most accessible and most overlooked tools available to South Florida service businesses.

Does using PO financing or contract-backed funding hurt my chances of getting an SBA loan? Not if it is structured correctly. In fact, using these tools well — and keeping each facility clean, matched to the right contract, and ring-fenced from your overall balance sheet — can actually strengthen your SBA profile over time. What hurts SBA eligibility is stacking short-term high-cost debt without a plan, not the use of asset-based financing tools.

What is the difference between accounts receivable financing and purchase order financing? AR financing is based on invoices you have already issued for completed work. Purchase order financing is based on a confirmed order or contract before the work is fully delivered. AR lines are common for businesses with steady recurring revenue. PO or contract-based financing is more appropriate when you need capital to fulfill an order or contract up front.

How much revenue do I need to qualify for contract-based financing in Florida? Most contract-based facilities start at $100K to $150K in contract value, though some PO lenders will work with transactions as small as $50K. The more important factors are the creditworthiness of your customer and the clarity of the contract terms. Bayside can help you assess whether a specific contract is box-worthy and which lenders are most likely to work with your situation.
