Due diligence

What to Look For

Practical guidance from hundreds of real acquisition conversations.

Recurring Revenue Quality

Ask for a breakdown of subscription and contract revenue versus one-time project fees.
Cloud platforms with multi-year customer tenures, MSPs with auto-renewing contracts, and consulting firms with managed services agreements all generate income buyers can count on.
The spread between recurring and project revenue tells you more about stability than almost any other single number.
Project-heavy revenue is still valuable, but it's worth understanding how much of the base comes back without a sales effort.

Team Depth and Credentials

Security clearances, vendor certifications like AWS or Microsoft, and compliance credentials like SOC 2 take years and real investment to earn.
Ask who holds what, whether those credentials transfer with the business, and which are held by individuals who could leave.
A team where project leads and account managers handle client work independently is the version of this business worth the most.

Customer Stickiness

Look for customers who would face real switching costs to leave — a cloud platform embedded in daily workflows, an MSP running a company's entire infrastructure.
Ask about tenure and what it would take for a typical customer to move to a competitor.
Long-tenured clients with multi-year contract history describe a business where customers stay because leaving is genuinely disruptive.

Proprietary Tools or IP

Ask what the business owns outright and how it's being monetized.
Homegrown tools, managed services platforms, or custom integrations add a revenue stream that scales without adding headcount.
Proprietary technology creates defensibility that pure services businesses don't have.

Client Concentration

Ask what percentage of revenue comes from the top three clients.
A single large government contract or one enterprise customer representing a significant share of revenue is worth examining carefully.
Long-tenured clients with multi-year contract history and deep team involvement tell a very different story than a new large client on a month-to-month arrangement.

IT Businesses in Illinois

How do I contact the owner of a business I found on Rejigg?

Create a free Rejigg account; owners, and the brokers who run some sales, only hear from buyers through the platform. Open the listing to see the full profile: city, team size, financials, what is for sale, and the reason for selling. Sign Rejigg's standard Fee & Confidentiality Agreement for that business; it is the same form for every deal. Verify your phone, then send your pitch from the listing. Replies, meetings, and documents all run through Rejigg.

Can I email Rejigg to get introduced to an owner?

No. Rejigg does not forward emails to owners or brokers, so a note to support@ or hello@ with a listing link will not reach them. Create a free account, open the listing, sign the agreement for that business, verify your phone, and send your pitch; that reaches them in a few minutes.

How does buying a business on Rejigg work?

Create a free account, set your criteria, and browse off-market businesses sourced directly by our team. When you find a match, reach out to the owner through the platform, Rejigg handles NDAs, scheduling, and document sharing so you can focus on the deal.

How much does it cost to buy a business?

Prices vary widely; most small businesses on Rejigg sell for $500K to $10M. Beyond purchase price, budget for diligence costs (attorney and accountant fees, typically $10K-$50K) and working capital reserves. Getting started on Rejigg is free.

What financing options are available?

The most common path is an SBA 7(a) loan, covering up to 90% of the purchase price with 10-year terms. Seller financing is also common, where the seller carries a note for 10-30% of the price. Our SBA loan calculator helps you estimate monthly payments.

How is Rejigg different from a broker or marketplace?

Brokers represent the owner and typically charge the owner 5–10% of the sale price. Marketplaces list whatever gets posted. Rejigg vets every listing, sources many of them directly through our own owner outreach, connects you directly with owners when they sell directly, and gives you tools to manage the process from first contact through closing.

What is due diligence and what does it involve?

Due diligence is the verification process after you and the owner agree on terms (usually in a Letter of Intent). Budget 30-60 days and $10K-$30K for professional help. A Quality of Earnings report is increasingly common for SBA-financed deals.

Can I buy a business with no money down?

Rarely. Most acquisitions require 10-20% down, whether through SBA financing, seller financing, or cash. Some creative structures can reduce the cash needed upfront, but sellers generally want to see you have skin in the game.
