Why This Risk Hides in Plain Sight
Open a SaaS listing with $18K in monthly revenue and a healthy customer count, and the multiple looks straightforward. What the summary numbers don't tell you is how many of those "customers" paid once, years ago, on AppSumo or a similar lifetime-deal (LTD) platform — and will never generate another dollar, while still expecting support, updates, and access forever.
Generic SaaS due diligence checklists cover churn, retention cohorts, and revenue concentration. Almost none of them mention lifetime deals specifically, even though a huge share of bootstrapped and indie SaaS tools have run at least one LTD campaign to fund early growth. If you're buying one of these businesses, that history doesn't disappear at closing — you inherit it.
What "Recurring Revenue" Actually Means When AppSumo Is Involved
A seller's "total customers" figure usually blends two very different populations:
- True subscribers: paying monthly or annually, cancel-able, the revenue a standard SaaS multiple is supposed to be pricing.
- LTD holders: paid once, often years ago, for permanent access. They show up in usage dashboards and support queues, but contribute zero forward revenue.
If a seller quotes Monthly Recurring Revenue (MRR) that blends both, or reports a customer count that's mostly LTD redemptions, the effective multiple you're paying on real recurring revenue is higher than the headline number suggests. This is the first adjustment to make before you even open a spreadsheet: ask for MRR calculated on subscription revenue only, with LTD accounted for separately.
The Liabilities Nobody Prices In
Perpetual support obligation. LTD buyers paid for lifetime access, which typically includes lifetime support and often "all future updates." You inherit that promise with no matching revenue stream to fund it — a support team sized for today's ticket volume, indefinitely, on a shrinking share of paying customers. Tax and VAT exposure as merchant of record. On many LTD platforms, the seller (not the platform) is the merchant of record and remains liable for sales tax, VAT, or GST across every jurisdiction where an LTD buyer was located — an obligation that can survive a change of ownership if it isn't cleanly assigned or settled at closing. Open refund windows. Most LTD platforms guarantee refunds for 30-60 days after purchase. If the seller ran a campaign shortly before listing the business, you could inherit an active refund exposure window with no visibility into how many buyers will exercise it. Roadmap and feature promises baked into old terms. Early LTD campaigns often promised "everything, forever" before the product had a real roadmap. If those buyers are still active, you may be contractually boxed into supporting features you'd otherwise deprecate. Platform rules on ownership transfer. Some LTD marketplaces restrict what happens to outstanding codes when the underlying company changes hands — read the platform's merchant terms, not just the acquisition contract, before assuming a clean handoff.How to Quantify the Damage Before You Offer
Ask the seller to split every core metric into two columns: subscription and LTD. Specifically:
- Subscription-only MRR and ARR, with LTD revenue excluded entirely (it's a historical one-time event, not a recurring stream).
- LTD cohort size, redemption date(s), and what percentage of the current support ticket volume that cohort generates.
- Total historical LTD revenue collected, and the platform's commission rate on it (many LTD platforms take a 70-30 or similar split favoring the platform), so you understand what the seller actually netted versus what was reported.
- Any outstanding refund windows tied to campaigns run in the last 60-90 days.
Once you have real subscription MRR isolated, apply your valuation multiple to that number — not the blended figure — and treat the LTD cohort's ongoing support cost as a cost line, not a rounding error.
The Due Diligence Checklist
- 1. Request the full LTD platform payout history — every campaign, redemption count, date, and net payout after platform commission.
- 2. Isolate subscription-only MRR/ARR from blended reporting, and re-run the valuation multiple against that number alone.
- 3. Ask for LTD-cohort support ticket volume as a share of total support load, to size the ongoing cost you're inheriting.
- 4. Check for open refund windows on any LTD campaign closed within the platform's refund period.
- 5. Read the LTD platform's merchant terms on change of ownership — some restrict or complicate what happens to outstanding codes after an acquisition.
- 6. Get written confirmation of what LTD buyers were promised (lifetime updates, specific features, support SLAs) so you know exactly what obligation transfers with the business.
- 7. Confirm who has been the merchant of record for tax/VAT purposes on LTD sales, and whether any liability is unresolved at closing.
How This Should Change Your Offer and Deal Structure
Price the multiple against clean subscription revenue, not blended MRR — this alone often moves the number more than any other single adjustment in a small SaaS deal. Beyond the headline price, three structural tools handle the leftover risk:
- Escrow holdback sized to cover any open refund window, released once the window closes without claims.
- Seller reps and warranties specifically covering LTD tax/VAT compliance and accurate disclosure of redemption history — not just the standard boilerplate.
- A support-cost adjustment in your post-close model, treating the LTD cohort as a fixed cost center you're managing down over time (through better self-serve docs, for instance) rather than a customer base you're growing.
Red Flags Specific to LTD-Heavy SaaS Listings
- Seller reports one blended MRR/customer number and can't (or won't) split subscription from LTD on request
- A large LTD campaign closed in the last 60-90 days, right before the business went up for sale
- No documentation of what past LTD campaigns promised buyers
- Support ticket volume disproportionately high relative to paying-subscriber count
- Seller is vague about who has held merchant-of-record responsibility for tax purposes
Frequently Asked Questions
Does having run AppSumo deals automatically make a SaaS a bad acquisition?No. Many well-run SaaS businesses use LTD platforms deliberately for early customer acquisition or cash runway, then transition primarily to subscriptions. The red flag isn't having run a lifetime deal — it's a seller who can't or won't separate its financial and support impact from the rest of the business.
Can I discontinue support for LTD holders after buying the business?That depends entirely on what was promised at the time of sale and the platform's own terms — this is a legal and reputational question, not just a financial one, and it's worth reading the original campaign terms rather than assuming.
How much should LTD history discount the price?There's no fixed percentage; it depends on cohort size, remaining support burden, and any unresolved tax exposure. The right approach is pricing the multiple against clean subscription revenue and separately accounting for the support cost and liabilities above, rather than applying a blanket discount to the headline number.
Is this only relevant to AppSumo specifically?No — the same due diligence applies to any comparable lifetime-deal platform. AppSumo is simply the largest and most common one you'll encounter in SaaS listings.
Key Takeaways
- Blended MRR/customer figures that mix subscriptions with lifetime-deal redemptions overstate the recurring revenue you're actually buying
- Perpetual support obligations and tax/VAT merchant-of-record exposure from past LTD sales survive a change of ownership
- Always request subscription-only MRR/ARR separated from LTD revenue, and re-run your multiple against that clean number
- Open refund windows on recent LTD campaigns are a real, quantifiable risk — check dates before you offer
- Escrow holdbacks and specific seller reps on LTD compliance are more useful here than a blanket price discount
