Before you agree

The right time to understand a contract is before the signature.

If you are financing an SMB acquisition with an SBA 7(a) loan, your lender is your gatekeeper. The diligence items they require are not optional, and the contract review they demand is different from the review an unfinanced buyer might accept. Understanding what the SBA lender cares about before you submit the loan package saves weeks of back-and-forth.

This guide covers the contract due diligence items SBA 7(a) lenders consistently require on SMB acquisitions in the $1M to $10M enterprise value range. It focuses on the contract review, not the broader financial diligence (QoE, tax returns, cash flow analysis), which is the CPA's lane.

The customer concentration review

Customer concentration is the first thing an SBA lender stress-tests, because a target that depends on one or two customers is a target that can lose most of its revenue in a single phone call. Lenders want to see the revenue breakdown by customer, usually for the trailing two to three years, and they get nervous as any single customer climbs past 20% of revenue. Above roughly 50%, most 7(a) loans become very hard to approve without additional structure.

On the contract side, the lender will look for written customer agreements, their remaining term, and whether they survive a change of ownership. Month-to-month relationships with a dominant customer, or contracts with a change-of-control termination right, are exactly the kind of thing that turns an approvable deal into a declined one. Surface the concentration early and bring the supporting contracts, because the lender will ask.

The lease assignment review

If the business operates from a leased location, the lease is a closing-critical document. The SBA loan generally requires a lease term, including options, that runs at least as long as the loan, which is typically 10 years. The lender will want the landlord's consent to assignment, and on real-estate-secured pieces, often a landlord waiver or subordination.

The red flags here are a short remaining term with no renewal options, a landlord consent right that lets the landlord block or re-trade the assignment, personal guarantee requirements that follow you onto the lease, and demolition or relocation clauses that could move the business out from under you. Get the assignment and the landlord consent moving early, because landlord timelines are outside your control and routinely become the long pole in the closing.

The key employee review

Many SMBs run on a small number of people, sometimes including the seller. The lender wants comfort that the business survives the transition. That means looking at employment agreements, non-compete and non-solicit terms for departing owners, and the retention plan for the people you need to keep. A seller who walks away on day one with no transition obligation, and no non-compete, is a risk the lender will flag.

Read the seller's transition services or consulting agreement for scope, duration, and compensation, and read the retained-employee agreements for retention incentives and restrictive covenants that are actually enforceable in the relevant state. The contract review here protects the cash flow the loan is underwritten against.

The seller financing note review

Seller financing is common on SBA deals, and under SOP 50 10 8, effective June 1, 2025, a seller note can only count toward your required 10% equity injection if it is on full standby, with no principal or interest payments, for the life of the SBA loan, and it cannot exceed 50% of the required injection. The lender will read the standby terms closely, because a note structured the wrong way will not count toward injection and can stall underwriting.

Beyond standby, the lender cares about subordination to the SBA debt, acceleration triggers, and default terms that do not conflict with the senior position. If you are leaning on the seller note to hit your injection floor, confirm the structure with your lender before you sign anything.

Personal guarantee requirements

The SBA requires a personal guarantee from anyone owning 20% or more of the borrowing entity, and the lender may require guarantees or a limited guarantee from owners below that threshold depending on the deal. Expect to personally guarantee the loan, and expect your spouse to be asked to sign in certain situations, particularly where community property or jointly held collateral is involved.

Read the guarantee for scope and for any collateral the lender takes, including a lien on your home in some cases. None of this is unusual on a 7(a) loan, but you should understand exactly what you are signing and have your attorney confirm the scope before close.

The diligence timeline SBA lenders actually run

SBA diligence runs in parallel with your own. Once you have a signed letter of intent and a loan application in, the lender orders a business valuation, often requires a quality-of-earnings or equivalent financial review, and begins collecting the contract documents above. The contracts the lender needs, the lease and landlord consent, the customer agreements, the seller note, the employment and transition agreements, are the same ones that gate your own decision to close.

The practical takeaway is to assemble the contract package early and review it before the lender does. Every issue you find and fix on your timeline is an issue that does not surface as a last-minute condition on the lender's timeline. The deals that close on schedule are the ones where the buyer ran the contract review ahead of the lender, not behind it.

How Inkvex's diligence output maps to SBA requirements

Inkvex reviews the exact contract set an SBA lender will scrutinize: the APA and disclosure schedules, the commercial lease and assignment, customer and vendor agreements, the seller financing note, and the employment and transition agreements. For each document it flags the red flags with the clause quoted, assigns a risk score from 1 to 10, and produces a first-pass attorney handoff. Because it reads the documents together, it surfaces the cross-document issues, like a customer contract that terminates on change of control conflicting with the concentration the loan is underwritten against, that decide whether the loan funds. Inkvex provides legal information, not legal advice, and the output is built to take to your M&A attorney and your SBA lender.
