## Executive Summary
Profitable B2B agencies and vertical SaaS companies doing $600k–$5M ARR use 10-year SBA 7(a) working capital and partner buyout loans at 9.75%–10.5% APR instead of giving up 20% equity or paying 35% APR revenue-based financing.

## Quantitative Reference Table
| Financial Metric | B2B Retainer Agency | Vertical B2B SaaS | SBA Cash-Flow Lending Rule |
| --- | --- | --- | --- |
| Gross Margin (%) | 55% – 68% | 78% – 86% | High gross margin offsets lack of real estate collateral |
| Net Dollar Retention (NDR) | 88% – 96% Annual | 104% – 118% Annual | Proves durable debt service capacity |
| Maximum Unsecured SBA 7(a) Loan | $500,000 – $2,500,000 | $500,000 – $5,000,000 | Underwritten primarily on Historical + Pro Forma DSCR >= 1.35x |

## Technical Breakdown & Actionable Protocol
Under SBA SOP 50 10 7.1, lack of fixed real estate collateral cannot be the sole basis for declining an SBA 7(a) loan when historical and projected cash-flow DSCR exceeds 1.25x.
