Understanding SBA Working Capital in SMB Acquisitions
Working capital in SMB acquisitions doesn’t get the attention it deserves. In acquisitions financed with SBA loans it can be the difference between thriving and being unable to make payroll. Despite its importance, working capital is often the least understood element of a deal, leading to post-close cash crunches that could have been avoided.
This guide distills the key lessons from industry veterans Heather Endresen (Viso Business Capital) and Chris Williamson (Cayne Crossing), drawing from decades of SBA lending and financial due diligence experience.
1. Why Working Capital Matters More Than You Think
Buyers and brokers often focus on Debt Service Coverage Ratio (DSCR) as the key metric for a safe deal. But Heather argues that working capital trumps DSCR in terms of real-world risk.
Why?
- The seller’s position is not your position. Sellers often operate mature, debt-free businesses with years of built-up liquidity. They may not fully appreciate the cash needs of a leveraged buyer.
- You’ll start with less cash and more expenses. Debt payments, growth initiatives, and system upgrades increase your cash outflows post-close.
- No second chances. Once the deal closes, lenders
2. Permanent vs. Seasonal Working Capital
Not all working capital is created equal. Understanding the difference is critical to financing it correctly.
| Type | Definition | Financing Best Practice | Common Mistake |
|---|---|---|---|
| Permanent | Cash always tied up in the business’s operating cycle | Include in purchase price or finance with equity/term loan | Funding with a line of credit (hard to repay) |
| Seasonal/Temporary | Short-term cash needs for a specific season or project | Fund with a line of credit | Treating seasonal needs as permanent, leading to over-borrowing |
| Key rule: Don’t fund permanent working capital with a revolving line—you’ll never pay it down. | |||
3. The Cash Conversion Cycle (CCC)
The CCC measures how long it takes for cash invested in operations to return as cash from customers:
Formula:
CCC = AR Days + Inventory Days + WIP Days − AP Days
- Working Capital Positive: Long CCC (≥30 days). Cash is tied up longer—more diligence required.
- Working Capital Neutral: Cash inflows roughly match outflows—easier to finance.
- Working Capital Negative: Customers prepay—ideal for cash flow, but deposits must transfer to the buyer at close.
4. Composition Matters
Not all “working capital” is equally helpful.
- Cash: Most liquid—ideal.
- Accounts Receivable (AR): Quality matters; large corporate clients pay slower but more reliably.
- Inventory/WIP: Harder to value and manage. Poor inventory systems can hide obsolete or overpriced stock.
5. Effective Purchase Price
Always calculate the effective price = purchase price plus required working capital.
Example:
- If you buy a business for $3.8M without working capital, you might need to add $200K from the term loan to fund it—bringing your effective purchase price to $4M,
- Whether working capital comes from the seller or from financing, your total cost is what matters—not just the base purchase price.
6. Customer Prepayments: The Hidden Risk
In negative working capital businesses, customer deposits can be a blessing—but only if they transfer to you.
- Watch for bad bookkeeping. Deposits may be misclassified as revenue or AR, masking their existence.
- Ask directly. Always include “Do you collect customer deposits?” in your diligence checklist.
- State compliance. Some states require deposits to be held in trust accounts.
7. Common Pitfalls to Avoid
- Not buying it = rebuilding it. If working capital isn’t included, you’ll have to build it from scratch.
- Assuming you can improve the CCC. Vendors may not extend you the same payment terms as the seller.
- Underestimating inventory complexity. Excess inventory usually exists for a reason—often customer expectations or bulk discounts.
- Overlooking deal structure impacts. In asset deals, you may be treated as a new entity, which can slow vendor credit approvals.
- Ignoring seller mindset. Many sellers resist including working capital because they’ve “earned” it—negotiating around this requires skill.
8. Best Practices for Buyers
- Include working capital in LOI terms to avoid late-stage disputes.
- Forecast working capital needs alongside P&L projections—especially in WC-positive businesses.
- Get a quality of earnings (QofE) report that includes a thorough working capital analysis.
- Secure an undrawn line of credit at close for seasonal or emergency needs.
- Overestimate needs. No one regrets having too much working capital; many regret having too little.
Key Takeaway
Working capital is not an afterthought—it’s a core part of the acquisition’s financial foundation. Treat it with the same rigor you apply to valuation and DSCR, and you’ll avoid one of the most common and costly buyer mistakes.
