This post presents the business acquisition process as a visual timeline diagram — proportioned by how long each stage actually takes relative to the others, which is easier to grasp at a glance than a plain list of steps. For the detailed explanation of each stage, see our 7-stage business acquisition process guide.
- The diagram is proportioned by relative time, not by importance — some short stages matter enormously despite taking little time.
- Sourcing occupies the largest visual share of the timeline, often several months.
- Financing and diligence run partly in parallel, which the diagram reflects as overlapping bars rather than a strict sequence.
- Online acquisitions compress the closing portion of the diagram since there's no real estate transfer involved.
The Timeline, Proportioned by Duration
| Stage | Relative Share of Timeline |
|---|---|
| 1. Define criteria | Short — 2–4 weeks |
| 2. Sourcing | Longest — 2–6 months |
| 3. Initial screening | Short per deal — 1–3 weeks |
| 4. Letter of intent | Short — 1–2 weeks |
| 5. Due diligence | Long — 4–8 weeks, overlaps with financing |
| 6. Financing & closing | Long — 4–6 weeks, overlaps with diligence |
| 7. Transition | Extends past closing — 30–90 days |
Why Sourcing Dominates the Diagram
Sourcing takes up the largest visual share because it involves the most rejected options — screening many listings, having several promising conversations fall through, and repeating that cycle until one deal actually fits. That's normal, not a sign you're doing something wrong; a compressed sourcing bar on paper doesn't match most buyers' real experience.
Where the Diagram Shows Overlap
Due diligence and financing are drawn overlapping rather than sequential because they typically run in parallel once you're under a signed LOI — your lender begins underwriting for a SBA loan for buying a business around the same time your accountant and lawyer are working through the due diligence checklist for buying a business. That overlap is one of the main ways the total timeline stays closer to six months than a year.
How Does This Diagram Shift for Different Business Types
For online or SaaS acquisitions, the closing stage compresses since there's no real estate or physical inventory to transfer — see our guide to buying an online business for how that process differs. For larger deals financed through a search fund business acquisition, the sourcing stage can stretch even longer, sometimes a year or more, since search fund buyers are typically targeting larger, harder-to-find businesses.
What If Your Own Timeline Doesn't Match This Diagram?
That's normal — this diagram shows typical proportions, not a guarantee. Running longer in sourcing usually just means your criteria are appropriately specific, not that something is wrong; running shorter in due diligence than the ranges shown here is worth a second look, since that stage rarely compresses without something being skipped. Use the diagram as a rough gut check on where you are, not a deadline to hit — a search that takes nine months instead of six isn't a failure if it ends with the right business.

FAQ
1. What does a business acquisition process diagram typically show?
A linear timeline with each stage's relative length, making it easy to see at a glance which parts of the process take the most time.
2. Which stage takes up the largest share of the timeline?
Sourcing typically takes the largest share, often several months out of a total six-month-to-a-year process.
3. Does the diagram apply to every industry the same way?
The general shape holds across industries, though online and SaaS acquisitions can compress the closing stage since there's no real estate to transfer.
4. Can stages overlap in the actual timeline?
Yes — financing pre-qualification can start during sourcing, and due diligence often overlaps with loan underwriting once a deal is under LOI.
