How long it takes to sell a software company
The honest answer, with data: advisor-run private sales run six to twelve months, larger and more complex processes run longer, and the difference between the fast and slow end of every range is preparation. Here is the full timeline, stage by stage.

| Route | Launch to close | Basis |
|---|---|---|
| Advisor-run private sale ($1M to $50M) | 6 to 12 months | IBBA Market Pulse Q4 2025; larger deals at the longer end |
| Axial closed-deal examples, launch to close | 7 to 17 months | Dated timelines from Axial Top Deals, Q1 2026 |
Ranges as published by each source; per-route citations in the sources section. Both series describe advisor-run processes in and around the $1M to $50M range.
The IBBA broker survey splits the 6 to 12 months roughly in half: the front half is preparation, marketing, and collecting offers. Once an LOI is signed, expect 2 to 4 months to closing on deals in our size range, and longer on larger ones, where due diligence alone can run 3 to 4 months. The front half is the part good preparation compresses.
| Stage | What happens | Typical duration | Source |
|---|---|---|---|
| Preparation | Financials cleaned, SaaS metrics standardized, data room built, positioning materials designed, buyer list curated | Shares the front half of the process with marketing; in Array mandates it is finished before launch | IBBA Market Pulse Q4 2025 (process split); Array Capital, published process |
| Marketing | Confidential outreach under NDA, management calls, buyer Q&A | The balance of the front half; outreach, management calls, and buyer Q&A run in parallel toward the offer deadline | IBBA Market Pulse Q4 2025 (process split) |
| Offers to signed LOI | Competing offers collected against a deadline and negotiated to a signed letter of intent | Array mandates typically run 3 to 5 months from preparation to a signed LOI; the average closed lower-middle-market deal draws 3.61 offers | Array Capital, published process; IBBA Market Pulse, 2025 closings |
| Exclusivity to close | Confirmatory due diligence, quality of earnings, legal documents, funds flow | 2 to 4 months from signed LOI to closing; due diligence alone can run 3 to 4 months on larger deals | IBBA Market Pulse Q4 2025, by deal size band |
| End to end | Decision to sell through money in the bank | 6 to 12 months advisor-run; 7 to 17 months in Axial's dated closed examples | IBBA Market Pulse Q4 2025; Axial Top Deals, Q1 2026 |
How long does it take to sell a SaaS company?
For most founders, 6 to 12 months from deciding to sell to money in the bank. That is the published range for an advisor-run private sale of a $1M to $50M company (IBBA / M&A Source Market Pulse, Q4 2025), and 2 to 4 months of it sit between the signed LOI and closing. Large or complex processes run longer: Axial's dated closed-deal examples span 7 to 17 months from launch to close.
The range is wide because the stages behave differently. The back half of the process, from signed LOI to closing, is largely on the buyer's clock: their diligence providers, their lawyers, their credit committee. The front half is on yours. That asymmetry is the single most useful fact in this report, because it means the compressible part of the timeline is the part you control before a single buyer has been contacted.
Preparation is where slow processes are made. Cleaning the financials, standardizing revenue metrics, assembling a data room, and writing materials that answer the questions buyers actually ask takes weeks when it is done deliberately and months when it is done reactively, one buyer request at a time. A process that launches before this work is finished does not skip the work; it does the work in front of the buyer, under exclusivity, with the leverage already handed over.
Marketing is faster than most founders expect when the pricing is right and slower than any forecast when it is not. A well-priced, well-prepared process draws its buyer interest early, because prepared materials give buyers something to decide on. The stall pattern here is dribbled outreach: contacting buyers one at a time, without a deadline, lets each of them wait for the others, and the calendar absorbs the cost.
Offers to LOI is where competition either exists or does not. The average closed lower-middle-market deal drew 3.61 offers in 2025 (IBBA), and getting several offers to arrive in the same window is a scheduling exercise, not luck. Our own mandates typically run 3 to 5 months from the start of preparation to a signed LOI because the offer deadline is fixed before launch. A process with one interested buyer and no deadline has no reason to converge, and usually does not.
Exclusivity to close is the stage founders underestimate most. Once the LOI is signed you are one buyer deep, the competitive tension is spent, and the remaining 2 to 4 months are an examination, not a negotiation. Everything that was true in the materials gets verified; everything that was optimistic gets repriced. Section 02 is about what happens when it gets repriced.
How long does due diligence take?
Plan for 2 to 4 months between a signed LOI and closing on a deal in the $1M to $50M range (IBBA Market Pulse, Q4 2025), and longer above it: on larger transactions due diligence alone can run 3 to 4 months. The long-run direction is up. Across 900+ larger deals studied by SS&C Intralinks and Bayes Business School, average diligence periods stretched from 124 days in 2008 to 2012 to 203 days in 2013 to 2022.
Two findings from that Intralinks dataset are worth holding together. First, diligence keeps getting longer everywhere, because buyers verify more than they used to: expect a quality-of-earnings review even on small deals, and expect every metric in your materials to be recomputed from raw exports. Second, faster is not simply better. Deals with medium-length diligence were the most likely to complete and resolved fastest after announcement; rushed diligence breaks buyer trust, and dragged diligence kills momentum. The practical target is not the shortest diligence but the smoothest one, which is a function of how complete the data room was on day one.
Deals die on surprises, and surprises are preventable
Axial dissected 75 LOIs that fell apart in 2025. The causes are not market conditions; they are preparation gaps.
View the data as a table
| Cause | Share of broken LOIs |
|---|---|
| Diligence findings (non-QoE) | 25.3% |
| QoE earnings discrepancies | 21.3% |
| Renegotiation breakdowns | 14.7% |
| Seller backed out | 13.3% |
| Financing failed | 10.7% |
| Business underperformed in process | 8.0% |
Nearly half of dead deals (46.6%) died on diligence surprises: findings the buyer had not been told about, or earnings that did not survive a quality-of-earnings review. Both are preparation failures, and both are preventable before launch. QoE-driven failures more than doubled since 2023; financing failures halved.
The market context makes the same point: in Axial's separate 2026 Outlook survey, 58.6% of lower-middle-market advisors closed more than half of the deals they took to market in 2025, and the top deal-killer they name is unrealistic valuation expectations (28.3%), ahead of diligence findings (24.5%).
Why do deals fall through?
Mostly on surprises, and mostly on the seller's side of the table. Of the 75 broken LOIs Axial dissected from 2025, 25.3% died on diligence findings the buyer had not been told about and 21.3% on earnings that did not survive a quality-of-earnings review. Together that is 46.6% of all dead deals lost to information the seller could have surfaced, framed, or fixed before launch. Renegotiation breakdowns (14.7%), sellers backing out (13.3%), failed financing (10.7%) and the business underperforming during the process (8.0%) account for most of the rest.
The anatomy of each cause matters, because each one dies at a different point on the timeline. Non-QoE diligence findings are the classic late-stage killer: a customer concentration nobody flagged, a licensing gap, a key contract with a change-of-control clause. QoE discrepancies are quieter and now more common; the same Axial dataset shows QoE-driven failures more than doubling since 2023, while financing failures halved. A buyer whose accountants recompute your EBITDA and land 20% below your number does not always walk, but the deal that survives is a smaller one. Renegotiation breakdowns and seller withdrawals cluster around the same moment, when a repriced offer meets a founder who anchored on the original number.
The 8% of deals that died because the business underperformed mid-process deserve their own sentence. A sale process is a tax on the founder's attention, and the longer it runs, the more it costs the business that is being sold. This is one reason process discipline and confidentiality are speed tools, not formalities: a leaked process distracts the team, unsettles customers, and shows up in exactly the monthly numbers the buyer is watching. Our approach to keeping a process quiet while still running it wide is documented on our confidentiality page.
Read the chart from the bottom up and it becomes an argument for preparation rather than a catalogue of misfortune. Financing risk is screened by qualifying buyers before they reach the table. Renegotiation risk is reduced by realistic pricing and by having more than one bidder to return to. And the 46.6% of deals lost to diligence surprises are addressed the same way every time: a sell-side diligence pass before launch, so the surprises are found by your own advisor rather than the buyer's. The operational version of that checklist is our playbook on how to sell a SaaS company.
Three findings that decide whether you run fast or slow
Price realistically and buyers arrive; overprice and they vanish.
Axial’s 2026 Outlook survey names unrealistic valuation expectations as the top deal-killer lower-middle-market advisors face, ahead of diligence findings. The single biggest schedule risk is launching at a fantasy number.
Diligence has an optimal length, and it is not "as fast as possible".
Across 900+ transactions, deals with medium-length diligence were the most likely to complete and resolved fastest after announcement (SS&C Intralinks / Bayes). Rushed diligence breaks trust; dragged diligence kills momentum.
Deals now take longer than they used to, everywhere.
Average due-diligence periods on larger deals stretched from 124 days (2008-2012) to 203 days (2013-2022, Intralinks). Buyers check more, so the data room has to be ready before launch, not during it.
Can a sale go faster?
Yes, and the evidence is on this site. Our Tabarnapp mandate drew three offers inside its first two months, ended in a bidding war, and closed five months after signing, against the published market average of 6 to 12 months end to end. The full case study is public. More generally, our mandates typically run 3 to 5 months from the start of preparation to a signed LOI, because the preparation is finished before the clock starts.
Nothing about a fast process is exotic, which is what makes the speed repeatable. The pricing is set where buyers respond: unrealistic valuation expectations are the top deal-killer lower-middle-market advisors name (Axial, 2026 Outlook), so a realistic number is worth months by itself. The data room is complete at launch, so diligence is a verification exercise rather than an archaeology project. And the offer deadline is fixed and real, so parallel buyer conversations converge on a date instead of drifting toward one. Speed here is not haste; the diligence-length evidence in section 01 argues against rushing the back half. It is the front half, the part on the seller's clock, where months are actually won.
If you are planning an exit in the next 12 months, the sequencing writes itself. Start the preparation now, before any buyer is contacted, using the step-by-step playbook; run the process wide, quiet, and against a deadline; and treat the LOI-to-close window as a verification of work already done. If you would rather pressure-test your own timeline against these benchmarks first, a discovery call is free and stays confidential.
How we compress the range. Our mandates run on a compressed front end: designed materials and a complete data room before launch, a hard offer deadline, and Q&A managed daily. The Tabarnapp process went from mandate to three offers inside its first two months and closed in five; every Array process carries a fixed offer deadline. Preparation is how a 6-to-12-month market average becomes your ceiling, not your floor.
Map your timeline on a callHow this report is built
Timeline statistics are the most casually invented numbers in M&A content, because nobody audits a duration. This report holds them to the same standard as a valuation figure: a named publisher, a dated source, and a stated population.
- Only figures verified at the publisher's own page or PDF appear here. Several widely-circulated timeline statistics could not be traced to their claimed sources and were excluded.
- Marketplace listing statistics are excluded by policy: they describe deals below the advisor-run segment this report serves, and their populations skew micro. Broker-survey data (IBBA) covers $500K to $50M.
- Large-deal studies (SS&C Intralinks, 900+ transactions) are used for direction on diligence dynamics, not as small-deal benchmarks.
- Every chart on this page is also published as a plain HTML table with the same figures, so the data is readable without rendering a single pixel.
- The master timeline table mixes market data with Array Capital's own published process figures. Every cell names its source, so you can always tell whose clock is being described: the market's, or ours.
- Durations are ranges, not promises. Where a stage's length is not separately published (preparation versus marketing inside the front half), we say so and label the split as the survey reports it, rather than inventing a precision the data does not have.
- Updated quarterly in place at this URL. First edition: July 2026; each refresh is logged here. Figures reflect data available as of July 2026.
- Every company's timeline is its own; the ranges here are the market's, and preparation is the variable you control.
