What a payments P&L tells a private equity sponsor

Private equity has learned payments. A decade ago, a software company's payments line was a curiosity in diligence. Today the sophisticated sponsors read it the way they read net revenue retention: as a signal of how much value the platform actually captures from the workflow it owns. Having built payments businesses inside two PE-backed software companies and advised sponsors on others, I can tell you what they look for, because it is exactly what operators should build toward.

Attach, take, and durability

Three numbers carry the conversation. Attach rate: what share of the customer base processes payments through you, and what is its trajectory? Net take rate: after interchange, network fees, and processor costs, what do you actually keep per dollar of volume? Durability: are those economics contractually yours, on your paper, portable through a change of control, or are they a referral arrangement that a processor can reprice or an acquirer will discount to near zero?

That third one is where deals quietly lose value. A payments line that is really someone else's program with your logo on it gets treated as low-quality revenue. The same volume, owned properly, re-rates the whole company, because buyers pay for revenue they can control and grow.

What the best operators build before the banker shows up

Clean per-account economics that tie to statements. Contracts that survive diligence: clear ownership of merchant relationships, no surprise exclusivity, no auto-renewals that hand leverage away. A pricing history that shows the program is managed, not abandoned. And a credible expansion story grounded in attach math rather than adjectives. None of this can be assembled in the six weeks before a process. All of it can be built in the two years before one.

The sponsors have learned to read the payments P&L. The operators who win are the ones who wrote it deliberately.
