Selling a B2B Marketplace: Questions Founders Ask

Net take-rate revenue, what your platform actually keeps after paying out to sellers or suppliers, is what a buyer should value the business on, not gross merchandise value flowing through the platform. Present both, but lead with net revenue, since a buyer who initially anchors on GMV will have to be walked back to the real number eventually, and that correction costs credibility.

The gap between the two numbers matters just as much as either figure on its own. A marketplace with a high take rate relative to its category signals real pricing power and defensibility, while a thin take rate that depends on volume alone is a fragile business model that a competitor with slightly better economics can undercut. Walk a buyer through how your take rate compares to the handful of comparable marketplaces they're likely already familiar with, rather than assuming they'll do that research themselves.

A marketplace where a small number of large sellers or buyers account for most of the transaction volume carries real liquidity risk, since losing one side of a concentrated relationship can meaningfully dent activity on the other side too. Show concentration by both buyer and seller side separately, and be ready to explain what retains each cohort beyond just being the only option available.

The strongest answer to a concentration question isn't denying the concentration exists, it's showing what makes each major participant sticky. Integration depth, whether a large seller has built tooling or workflows around your platform that would be costly to rebuild elsewhere, tends to matter more to a buyer than the raw percentage of volume that seller represents. A concentrated marketplace with deep integrations on both sides reads as far more durable than a diversified one where every participant could leave with a week's notice.

Often, yes, more than for most other categories in this comparison, since Acquire's audience is genuinely software and technology literate and marketplace economics are a familiar model to them. Flippa's broader marketplace and brokered path for larger deals also reach buyers comfortable with digital platforms, so both are worth testing rather than assuming one is clearly better.

For a marketplace above a certain size, a brokered process through Flippa's larger-deal track, or a dedicated M&A advisor familiar with two-sided platforms, often surfaces buyers neither general marketplace would reach on its own, private equity groups building a platform strategy in your category, or a strategic acquirer already adjacent to your space. Testing both self-serve platforms first still makes sense, since it costs little and helps calibrate what a realistic range looks like before engaging a more expensive brokered process.

Beyond financials, expect real scrutiny of platform uptime, payment processing and escrow mechanics, dispute resolution volume and outcomes, and how liquidity is seeded in new categories or verticals. A marketplace that can show a repeatable playbook for launching and growing new categories reads as a more durable, transferable asset than one where growth depended on one-off founder effort.

Dispute resolution deserves particular attention, since it's where a buyer sees how your platform actually behaves under stress rather than how it performs when everything goes smoothly. A low dispute rate with clear, documented resolution outcomes signals trust infrastructure a buyer can rely on. A high dispute rate, or one with no consistent resolution process behind it, raises real questions about whether the platform's trust and safety mechanics can scale past your own personal involvement in handling edge cases.

Have these operational records ready before diligence starts:

• Platform uptime history, so a buyer can see how reliable the marketplace has been for both sides of every transaction.
• Documentation of payment processing and escrow mechanics, including how funds move between buyers, sellers and your platform.
• Dispute resolution volume and outcomes, showing how often problems arise and how you settle them.
• A repeatable playbook for launching new categories or verticals, with notes on how liquidity was seeded in each one.

Expect a multiple tied to net revenue growth and liquidity durability, with buyers on either platform likely to structure part of the price as an earnout tied to retained transaction volume through a transition period. Push for earnout triggers based on platform-level metrics you can verify independently, rather than terms that depend on the buyer's own post-close reporting alone.

The most contested term in a marketplace earnout is usually how liquidity gets measured after close, whether by raw transaction volume, net revenue, or active buyer and seller counts. Each measure rewards different behavior from a buyer who might have incentives to grow one metric at the expense of another during the earnout window. Agree on the exact metric and how it's calculated before you sign, since a dispute over measurement after the fact is far harder to resolve than negotiating clear terms upfront.
