This post walks through the full business acquisition process from first search to closing, breaking it into seven stages with a typical timeline for each one, so you know roughly where you are in the process and what comes next at any given point.
- The process runs through seven stages: search criteria, sourcing, initial screening, letter of intent, due diligence, financing and closing, and transition.
- Most first-time buyers should budget six months to a year from starting a serious search to closing.
- Due diligence and financing usually take the longest of any single stage, often eight to twelve weeks combined.
- A letter of intent (LOI) — a non-binding outline of proposed deal terms — is what moves a deal from negotiation into formal due diligence.
What Are the Main Stages of the Business Acquisition Process?
Every acquisition, regardless of industry or size, moves through roughly the same seven stages. The table below lays them out in order with a typical duration for each, functioning as a rough timeline for the whole process.
| Stage | What Happens | Typical Duration |
|---|---|---|
| 1. Define criteria | Set your target industry, size, location, and price range; get financing pre-qualified | 2–4 weeks |
| 2. Sourcing | Search listings, work with a broker, and network for off-market opportunities | 2–6 months |
| 3. Initial screening | Review financials at a high level and meet the seller to confirm real interest | 1–3 weeks per deal |
| 4. Letter of intent | Submit a non-binding LOI outlining proposed price and terms | 1–2 weeks |
| 5. Due diligence | Verify financials, legal standing, contracts, and operations in detail | 4–8 weeks |
| 6. Financing & closing | Finalize loan approval, sign the purchase agreement, transfer ownership | 4–6 weeks |
| 7. Transition | Work with the seller to hand off relationships, systems, and institutional knowledge | 30–90 days post-close |
How Long Does the Whole Process Actually Take?
Most first-time buyers should plan for six months to a year from the point they start a serious, criteria-driven search to the day they close. Sourcing the right business usually takes longer than any other single stage — it's common to screen dozens of listings and have several deals fall apart before one makes it to a signed LOI. Once you're under an LOI, the process tends to move faster and more predictably, since due diligence and financing typically run in parallel rather than back to back.
What Happens During Due Diligence?
Due diligence is the stage where you verify everything the seller has told you before you're contractually locked in — financial statements, tax returns, customer contracts, leases, licenses, and pending liabilities all get reviewed in detail, often with an accountant and lawyer involved. See our due diligence checklist for buying a business for the specific documents to request. Skipping or rushing this stage to close faster is one of the most common reasons buyers end up with problems they didn't see coming after the deal closes.
What Documents and Advisors Do You Need Along the Way?
You'll typically need a business broker or your own sourcing network during stages one through three, a lawyer to review the LOI and purchase agreement starting around stage four, and a lender — often for an SBA loan — engaged from stage one so financing isn't the bottleneck later. If you're working with a broker on the buy side, see our guide to broker client agreements for what that relationship should look like before you start. For legal representation specifically, our guide on finding a lawyer for buying a business covers when to bring one in and typical costs.
What Trips Up First-Time Buyers Most Often?
Underestimating how long sourcing takes is the most common one — many first-time buyers expect to find the right business in a few weeks and end up discouraged months in, when a multi-month search is actually normal. Pricing based on hope rather than verified financials is another: the IBBA and M&A Source's Q1 2026 Market Pulse survey shows realistic multiples typically landing between roughly 2.0x SDE and 4.0x EBITDA depending on the business's size and quality, a useful gut check against a seller's asking price. Rushing due diligence to keep a deal on schedule is the third — pressure to close by a certain date shouldn't come at the cost of skipping verification steps.

FAQ
1. What is the first stage of the business acquisition process?
Defining your search criteria and getting financing pre-qualified — before you look at a single listing, you need to know what size, industry, and price range you're actually targeting and what you can realistically finance.
2. How long does the full business acquisition process usually take?
Most first-time buyers should expect six months to a year from starting a serious search to closing, with the search and evaluation phase typically taking longer than the closing process itself once a deal is under a signed letter of intent.
3. What's the difference between a letter of intent and a purchase agreement?
A letter of intent is a non-binding outline of proposed deal terms used to move into due diligence, while the purchase agreement is the final, binding legal contract signed at closing.
4. Can you skip due diligence to close a deal faster?
You shouldn't — due diligence is where financial, legal, and operational problems surface before you're contractually committed, and skipping or rushing it is one of the most common reasons acquisitions go wrong after closing.
