SBA loans for scientific and technical consulting firms: expertise as the business, and priced like it

What this code covers

NAICS 541690 is a catch-all for firms that advise businesses and public bodies on scientific and technical questions not covered elsewhere: energy and utility-program consulting, workplace safety and industrial hygiene, agricultural and food-science advice, chemistry and physics consulting, and similar specialist practices. Several close neighbors have codes of their own: environmental consulting, engineering services, testing laboratories and logistics consulting.

What these firms share, from a lender's seat, is a structure: a principal or two with credentials, a handful of staff, revenue billed by the hour, the project or the contract, and very little on the balance sheet besides receivables. The median firm in these approvals supported 2 jobs.

The approvals, read against the national figures

From FY2024 through June 2026, 97 lenders approved 454 7(a) loans to these firms, worth $120,839,500.

The rate stands out. A quarter of these loans priced at 12.25% or more. Two things push it up. First, size: most loans fall in SBA's higher cap tiers, base plus 6% from $50,001 to $250,000 and plus 6.5% at $50,000 or less. Second, these firms have little collateral behind the loan, and 47.8% went through SBA Express, where the guaranty is 50% and the lender keeps more of the risk. How far a lender prices toward the cap is its own judgment about the file. See SBA's maximum interest rates and SBA 7(a) vs SBA Express.

What a lender finds on a consulting firm's balance sheet

SBA lenders do not decline a loan for lack of collateral alone, and every owner of 20% or more personally guarantees it. Because the firm's value sits in one or two people, lenders may also require life insurance on a principal, assigned to the lender. See who guarantees an SBA loan and will an SBA loan take my house.

Why so few start-ups

Only 2.9% of loans went to new firms, and 0.4% to franchises. A consultant leaving a larger practice to open their own often needs little capital: a laptop, insurance and a few months of living expenses. Those who do borrow are generally asking for working capital against contracts they already hold, and a lender wants to see a year or more of billing before it will lend on it.

A start-up that does apply needs an equity injection of at least 10% of total project costs, a resume that shows the principal can win and deliver the work (it supports Form 1919), and ideally letters or contracts from the first clients. See SBA Form 1919.

Contracts, clients and the cash cycle

Who pays. Many of these firms work for utilities, government agencies, manufacturers or large institutions. Such clients almost always pay, but slowly and on their own schedule, and a small firm can be short of cash while owed a great deal. A lender reads the receivables aging by client to see how long collection really takes.

How concentrated. A safety consultant with one industrial client, or an energy consultant running a single utility program, can lose most of its revenue when a contract is rebid. Lenders ask for revenue by client and contract end dates. See customer concentration and debt.

What is contracted. Multi-year contracts, master service agreements and task orders make revenue more predictable than project-by-project work, and a lender will give credit for them. Where the need is to fund work on a specific contract, contract financing or a line may fit better than a term loan; see borrowing against a signed contract and lines of credit for government contractors.

Coverage is tested the usual way: SBA requires at least 1.15x, and 1.0x globally once the owners' personal income and debts are counted.

In a consulting firm, the question behind every other question is what happens to the revenue if the principal stops working.

Buying a technical consulting practice

Seventeen loans, 3.7% of the total against 10.4% nationally, financed a change of ownership, at a median of $495,000 and a median rate of 9.5%, well below the industry's median rate, in part because larger loans fall in SBA's lowest cap tier, base plus 3% above $350,000.

Consulting practices are often sold with earnouts tied to client retention. SBA prohibits an earnout to the seller in a change of ownership it finances, so an SBA buyer bridges the gap with equity and, if the seller agrees, a note. A seller note counts toward up to half of the 10% equity injection only on full standby for the life of the loan; a paying note is debt in the coverage test. See earnout vs seller note.

The seller cannot stay as an owner, officer or employee, but may consult for up to 12 months, or up to 24 months under SOP 50 10 8.1 from 1 October 2026. In a practice built on the seller's name, that window decides whether clients stay. Because nearly the whole price is goodwill, SBA's independent valuation applies whenever the amount financed, less appraised real estate and equipment, exceeds $250,000. From 1 October 2026, every change of ownership needs financial due diligence and must show 1.25x coverage on historical results. See financing a consulting firm acquisition.

Preparing a consulting firm's file

Start with SBA's standard list: business tax returns for 2–3 years, a P&L and balance sheet with a year-to-date P&L through last month-end, a debt schedule with copies of notes being refinanced, and personal tax returns and a personal financial statement for each owner of 20% or more. For a technical consulting firm, add:

• A contract list: client, scope, value, start and end dates, and renewal history
• Revenue by client for each year
• An accounts receivable aging by client, with days outstanding
• Resumes, licenses and certifications for the principals
• Professional liability insurance declarations

SBA 504 financed 18 projects at a median of $588,000, the route for a firm buying the office or lab space it occupies.
