You’re under LOI and the clock is ticking. The question every buyer asks within the first 48 hours is some version of: “How long is this actually going to take and what should I do next?”

The honest answer, and we’ll explain exactly why, is three to four weeks for most engagements, with the possibility of getting it done in two if you move fast, and the very real possibility of it stretching longer if the deal gets complicated.

The factors that drive a diligence timeline are real and specific, and understanding them upfront will change how you manage your deal, your lender, and your own expectations through the process.

Why Diligence Timelines Vary 

Before getting into the week-by-week breakdown, it’s worth being direct about something: “it depends” is genuinely the most accurate starting point when it comes to diligence timelines, and it depends on a handful of specific things.

The biggest variable, by a significant margin, is whether we can reach the seller and broker directly. When we can communicate with them without routing everything through the buyer, document requests move faster, follow-up questions get answered faster, and the whole engagement tightens up. 

Close behind that is seller responsiveness. How quickly does the seller turn around a document request? How available are they when we need clarification on something? A seller who responds within 24 hours and a seller who takes five days to respond to the same request can easily represent a week or more of difference in total timeline with nothing else changing.

Deal complexity matters too. A single-location business with clean books looks different to a multi-location operation with three years of mixed accounting and multiple entities. More variables mean more time to work through them properly.

The Week-by-Week Map

What follows is how a typical full QoE engagement actually unfolds. These are the phases we move through on every deal, calibrated to what actually happens when things are going smoothly.

Week 0: Kickoff (Under 24 Hours)

The moment you engage, onboarding begins. Our side of this is fast: under 24 hours to process your LOI, intake your deal information, and get the engagement structure in place.

What happens during kickoff: we review whatever data room or documents you’ve already gathered, consolidate them into our own data room to avoid duplicate requests, and set up the document request tracker which is a shared Google Sheet that gives everyone on the deal full visibility into exactly what’s been provided, what’s outstanding, and what we’re waiting on. 

One thing we do that speeds the whole process up, whenever a buyer is comfortable with it, and the overwhelming majority are, is we communicate directly with the seller and broker from day one. Allowing the buyer to step aside as the main point of contact for the seller can help shave days off the document collection process. 

Week 1: Document Collection

This phase starts on day one and runs concurrently with analysis, but in practice the first week is dominated by document collection. How long it takes depends almost entirely on seller responsiveness and what they’re able to provide.

What we’re typically requesting: P&Ls, bank statements, tax returns, credit card statements, and access to their bookkeeping software if possible. 

Weeks 1–3: Diligence

This is where the actual analysis happens, and it takes the most time of any phase. While document collection for supporting docs is still moving forward in the background, we’re running the financial review in parallel to set a baseline.

Here’s what’s happening behind the scenes as we work through diligence:

  • Quality of revenue and expenses — reviewing the methodology behind how financials are prepared, including assumptions, adjustments, and allocations, and assessing key trends in revenue and direct operating costs
  • Proof of cash — reconciling bank statements to reported revenue to confirm the numbers on the P&L match what actually hit the bank account
  • Add-backs and management adjustments — identifying and reviewing any adjustments to normalize EBITDA, including out-of-period, nonrecurring, unusual, and non-cash items
  • Risk assessment — identifying customer and vendor concentration, off-balance sheet liabilities, accrued liabilities, and any environmental or litigation-related red flags, plus a light tax review
  • Balance sheet review — analyzing working capital trends, accounts receivable aging and bad debt, accounts payable aging, inventory composition, and prepaid expenses
  • CAPEX analysis — reviewing capital expenditure trends and requirements to understand what the business actually needs to sustain operations going forward

As the analysis surfaces questions, for example a payment that needs a supporting document, a line item that doesn’t reconcile, or a related-party transaction that requires context, we go back to the seller with targeted follow-up requests. 

The depth and complexity of this phase is what makes a QoE different from a cursory financial review. We’re confirming whether the numbers are accurate, sustainable, and fairly presented, which ultimately takes time and a team to do properly. 

Weeks 3–4: Delivery

Once the analysis is complete, we move into final review and delivery. The end product is a comprehensive PDF report you can use to make an informed buying decision and share directly with your lender or any investors involved in the deal.

The report covers normalized EBITDA for the past two fiscal years and TTM, financial review and key trends analysis, and everything we found across the financial analysis, risk assessment, and balance sheet review. 

If you’re doing a QoE Lite rather than a full QoE, this stage moves a little faster because the deliverable is a cleaned-up working Excel file with commentary rather than a full PDF report, which means less production time at the end.

After delivery, support from our team is still available. You have direct access to your dedicated CPA throughout the process and ongoing support after the report is delivered to walk through findings, answer questions, and help you understand what the numbers mean for your next steps.

What Impacts the Timeline

The same variables consistently push the timeline shorter or longer. Here’s what to watch:

  • Direct seller and broker access — when we can communicate directly without routing through the buyer, the whole process tightens up. This is the default on most deals and the single biggest driver of a faster timeline.
  • Seller responsiveness — a seller who turns around document requests within 24 hours versus one who takes five days can represent a week or more of difference on its own. We’ll keep nudging, but there’s a limit to how hard you push someone who’s still running a business. Sometimes sellers go on vacation mid-diligence. It happens, and it has a real cost when you’re working against a deadline.
  • Document format — Excel exports and direct bookkeeping software access move significantly faster than PDF-only documents that require manual conversion. Not a dealbreaker, but it’s a time factor.
  • Buyer responsiveness — when a material finding or renegotiation point surfaces and needs your input, how quickly you engage directly affects how fast the engagement moves forward.
  • Material findings — if the EBITDA or SDE we arrive at is materially different from what was presented, the process pauses while you and the seller work through what that means. That conversation has to happen before we can wrap up.
  • Deal complexity — multiple locations, mixed entities, or unusual structures mean more variables to work through. More time, not necessarily more problems.

How to Think About This Relative to Your Other Deadlines

Your LOI exclusivity window, your lender’s underwriting timeline, and your target closing date all intersect with the diligence timeline in ways worth thinking through before you engage.

The goal is always to deliver a few days before your exclusivity window closes to give you enough buffer that you have time to actually process the findings and take any necessary next steps. That’s what we aim for on every engagement.

When that buffer gets compressed because document collection ran long, or a material issue required renegotiation, the right move is to get ahead of it early rather than let the clock run out. 

In practice, when a seller or broker sees that diligence is actively underway and the delay has a legitimate cause, extensions are almost always available. We rarely see a seller or broker refuse a reasonable extension when the process is clearly moving and the cause is legitimate.

The LOI exclusivity window exists to prevent indefinite drag, not to pressure everyone into a corner. When things are moving in good faith, that’s generally understood by all parties.
