733Park advises ISVs and independent software vendors on sales and acquisitions. Every engagement is senior-led by Lane Gordon and focused on companies with $5M to $350M in enterprise value.
If you are looking for the best M&A advisor for ISVs, the honest answer is that it depends on what your software company actually is. And for a growing number of ISVs, the answer is that you are partly a payments company, which changes who buys you and what they pay.
Why ISVs with embedded payments are strategic targets
Software that owns a vertical workflow sits in the most valuable position in commerce: the point where money moves. When an ISV embeds payments, it stops being just a software vendor and becomes the system that controls transaction flow for its entire customer base. Acquirers understand this. A payments company that buys an ISV is not just buying ARR. It is buying distribution, merchant relationships it did not have to originate, and processing volume with software-level retention wrapped around it.
That is why ISVs with embedded payments consistently attract strategic interest that pure software peers do not. The buyer is acquiring two revenue engines in one company, and the second engine often grows faster than the first.
Payments attach rate as a value driver
The single most examined number in an ISV sale with a payments component is attach rate: what share of your customers process payments through you, and what share of their volume you capture. A high attach rate proves the model works. A low attach rate with a credible plan is an upside story, and buyers will pay something for upside, but far less than for proof.
Alongside attach rate, buyers scrutinize your economics per merchant, the structure of your processing relationships, and how portable those arrangements are in a sale. This is where deals get technical. Residual streams, processor contracts, and revenue-share terms can materially move enterprise value, and they are exactly the details generalist advisors gloss over.
Who buys ISVs
Three buyer groups dominate. Payments companies buy ISVs to own software distribution rather than rent it through partnerships. Vertical SaaS consolidators buy to add products and payments volume to platforms they already run in your industry or an adjacent one. Private equity firms buy ISVs as platforms or add-ons, and payments monetization is frequently the thesis that justifies the price.
Each group underwrites the deal differently. The payments strategic models your processing volume. The consolidator models cross-sell. The sponsor models the monetization ramp. A well-run process forces all three to bid on their own best version of your company.
Why 733Park
Payments M&A is where 733Park started, 25 years ago, and it remains the core of the practice, alongside comparable depth in fintech, vertical SaaS, and AI. We have facilitated more than $10 billion in transaction volume across 209+ deals. When your ISV's value rests on embedded payments, that depth is the difference between an advisor who can defend your attach-rate story in a negotiation and one who is learning the vocabulary during your process.
Engagements are senior-led from start to finish. You work directly with Lane Gordon, and most deals close within four to six months from kickoff. We also advise ISVs on exit readiness, including how to build or improve payments monetization before going to market, because a year of attach-rate progress can change your outcome meaningfully.
