Valuation of a SaaS company, and when SBA financing fits

Published October 25, 2026 · Rules checked against SBA and IRS sources as of October 2026

Short answer

SaaS companies are valued on the durability and growth of recurring revenue: annual recurring revenue (ARR), gross and net revenue retention, churn, gross margin and the cost to acquire customers. Fast-growing companies are often priced on revenue; mature, profitable ones on earnings. SBA 7(a) acquisition loans fit the second kind, because SBA requires debt service coverage from historical cash flow, and projections can't be relied on to meet it.

Metrics that drive value

MetricFormulaWhy it matters
ARRMonthly recurring revenue x 12Scale of the subscription base
Gross revenue retention(Starting ARR - churn - downgrades) / starting ARRHow sticky revenue is
Net revenue retention(Starting ARR - churn - downgrades + expansion) / starting ARRGrowth from existing customers
Gross margin(Revenue - hosting and support) / revenueCash each dollar of revenue produces
CAC paybackAcquisition cost / monthly gross profit per new customerCost of growth

Illustration, not a real company. Starting ARR $2,000,000; churn $160,000; downgrades $40,000; expansion $240,000.

Gross retention = ($2,000,000 - $160,000 - $40,000) / $2,000,000 = 90%. Net retention = ($1,800,000 + $240,000) / $2,000,000 = 102%.

Where SBA fits

From ARR to cash flow a lender can use

SaaS valuations quoted as multiples of ARR suit fast-growing companies whose value is in future scale. An SBA lender needs something different: historical, verified cash flow covering debt service. Translating one to the other usually means a few adjustments that SaaS founders don't always make in their own reporting.

Illustration, not a real company. ARR $2,040,000. Reported EBITDA $720,000, but $150,000 of developer pay is capitalized and the founder (paid $80,000) does work a market hire would cost $180,000 for. Adjusted cash flow: $720,000 - $150,000 - $100,000 = $470,000. That figure, not ARR, is what a 1.25x coverage test runs on.

Diligence specific to software

When SBA financing fits a software acquisition

ProfileSBA fitWhy
Profitable niche SaaS, steady churn, founder exitingGoodHistorical cash flow can support debt; transition can be planned
Fast-growing, break-even, reinvesting everythingPoorNo historical coverage; value rests on projections SBA won't rely on
Profitable, but one customer is 40% of ARRDifficultLosing that customer breaks coverage; expect more equity or a lower price
Agency or services business with some softwareOften goodValued on services earnings; software adds stickiness

Software businesses also have little hard collateral, so the lender's case rests almost entirely on the durability of recurring revenue, the buyer's ability to run the product, and a technical handover the seller commits to within SBA's 24-month consulting limit.

Buyers can read OKtoBuy's guide to buying a SaaS business.

For lenders, the shortest summary is: ignore the ARR multiple, verify the cash, stress the biggest customers, and make sure the code and the people who understand it come with the business.

Financing ecommerce and online business acquisitions

An SBA 7(a) loan can finance buying an online business if it's an eligible, U.S.-based operating business with verifiable historical cash flow. SOP 50 10 8.1 lets lenders replace the physical site visit with documented alternatives (virtual meetings, business records) for e-commerce. The harder parts are revenue that depends on one platform or ad channel, inventory and supplier concentration, and earnings that need careful verification against tax returns and payouts.

Online businesses can be very financeable when they have a few years of clean, taxed profits. They're hard when the story depends on recent growth or on one channel.

Lender concerns, and how to address them

ConcernWhat helps
Platform dependence (one marketplace)Account health history, multiple channels, own-site sales share
Ad spend driving salesStable contribution margin after ads over 24-36 months
Supplier concentrationContracts, alternate suppliers, inventory on hand
Earnings verificationTax returns and transcripts tie to marketplace payouts and bank deposits
TransferabilityAccounts, trademarks, domains, software and supplier relationships transfer in the APA
Owner dependenceDocumented processes; seller consulting up to 24 months
Tying ecommerce revenue out Gross sales − fees, refunds,ads Payouts Deposits andtax return

Practical points

Ecommerce and marketplace sellers

Online businesses that sell physical products through their own site or a marketplace raise different questions from SaaS. Revenue may depend on one platform's rules and fees, advertising costs can swing margins quickly, and inventory and returns need careful treatment. A lender will want the platform's own sales reports reconciled to bank deposits and tax returns, a view of how concentrated sales are by product and channel, and confirmation that the seller's accounts, listings and supplier relationships can actually be transferred. Coverage still rests on historical, verified cash flow. Valuers should normalize advertising to a sustainable level rather than accepting a year in which ad spend was cut to flatter profit.

Questions to ask before financing a software or online business

  1. Which customers or channels would break coverage if lost?
  2. Can the code, domains, accounts and contracts transfer, and who holds the credentials today?
  3. What does a market-rate replacement for the founder's role cost?
  4. How much revenue is prepaid, and what does the buyer owe customers for it?

For online businesses of any kind, the strongest SBA files show verified earnings that do not depend on one customer, channel or platform, clean transfer of every account and asset the business runs on, and a seller who stays long enough to hand over the technical and supplier knowledge the buyer will need. The weakest rest on growth projections and an ARR multiple, which SBA rules do not let a lender rely on.

Examples on this page are illustrations, not real companies. Valuation and financing of online businesses depend heavily on verified data from the platforms they run on, so expect lenders and valuers to ask for direct reports rather than screenshots.

Lenders should also confirm that customer data handling meets the obligations in customer contracts, because a breach after closing can cost the buyer both customers and cash.

Common questions

Is deferred revenue a liability in a SaaS deal?

Yes. The buyer must deliver service already paid for; purchase agreements and the QoE usually treat it as debt-like or adjust working capital.

Can an SBA loan buy an unprofitable SaaS?

Generally not on SBA terms: the loan must meet DSC (1.25x for an Initial Acquisition) from historical, verified earnings.

What does net revenue retention tell you?

Whether existing customers spend more or less over time. Above 100% means expansion outweighs churn.

Is ARR the same as revenue?

No. ARR annualizes current recurring subscriptions; revenue on the income statement is what was earned in the period. A QoE reconciles the two.

Who should value a SaaS company for an SBA loan?

A Qualified Source engaged by the lender, ideally with software experience. At $3 million or more, a QoE also tests recurring revenue and deferred revenue.
