It's not the revenue number. It's not the multiple. It's what's sitting underneath both of them.#
A free multiple calculator and a $5,000 quality of earnings (QoE) report can start from the exact same top-line revenue and land tens of thousands of dollars apart on what the business is actually worth. That gap isn't rounding error. It's the difference between a number and a number someone actually tested.
What a multiple calculator does#
A multiple calculator takes revenue (or a rough SDE estimate) and multiplies it by an industry-standard range. That's the whole mechanism. It has no way to know if last year's revenue included a one-time contract that won't repeat, whether 40% of that revenue sits with a single customer, or whether the "profit" includes $80,000 of deferred maintenance the new owner will have to pay for in year one. It takes the inputs at face value because it has no way to do anything else.
What a QoE report actually tests#
A QoE report recasts the financials line by line and checks whether the earnings are real, recurring, and transferable. Three failure modes show up constantly:
Revenue that isn't recurring. A single large contract, a pandemic-era demand spike, or a customer that already gave notice can inflate a trailing twelve months without inflating what the business will actually produce next year. A QoE report normalizes for this. A multiple calculator has no line for it.
Add-backs that don't hold up. Sellers often add back the owner's salary, a personal vehicle, or a family member's paycheck to arrive at SDE. Some of these are legitimate. Others are wishful thinking, like adding back a "one-time" expense that shows up every year, or add-backs that push a $40,000 SDE figure to $70,000 without documentation. A buyer's QoE team will strip these back out, and if the seller's number was built on them, the gap surfaces during diligence instead of before the listing goes live.
Deferred costs that transfer to the buyer. Skipped equipment maintenance, understaffed roles the owner was covering personally, or software the business will need to replace post-close all reduce the real earnings power of the business, even though they don't show up as a line item on a P&L. A multiple calculator can't see any of this. A QoE report is built specifically to find it.
The fix#
Get a professional valuation before listing, not a rough multiple estimate, so add-backs are documented and defensible before a buyer's team tests them.
Normalize SDE with actual backup: receipts, invoices, payroll records for any family members on the books. Undocumented add-backs get discounted or rejected outright during diligence.
Flag recurring vs. non-recurring revenue explicitly. If a chunk of last year's revenue came from a contract that won't repeat, say so upfront rather than let a buyer discover it and question everything else in the file.
Account for deferred capex and understaffing honestly. A buyer will find it either way. Disclosing it upfront preserves trust in the rest of the numbers.
Where Openfair fits#
This is exactly why Openfair pairs sellers with CPA-backed valuation support instead of leaving them with a free calculator and a guess. The add-backs get documented before a listing goes live, which means the number a seller sees at the start of the process is closer to the number that survives a buyer's due diligence at the end of it.
A valuation that hasn't been stress-tested isn't a valuation. It's a starting point for a negotiation you haven't had yet.
