Who we serve

Sell Your ISO or Merchant Portfolio

ISOs and merchant portfolios are where 733Park started, and they are still core to what we do. Whether you are selling a residual stream, a book of merchants, or the whole company, we know what buyers pay and why, because we are in the market every month.

Get a confidential valuation

For more than 25 years, 733Park has done one thing: put payments, fintech, and SaaS deals together. We have closed more than 200 transactions representing over $10 billion in deal volume. Our clients have enterprise values from $2 million to $350 million, and every engagement is led personally by our founder. When you hire 733Park, you get the person who has done this for 25 years, not a junior associate.

What drives your valuation

Attrition: the single biggest multiplier. Low attrition books command premium pricing.
Processor relationships: portability and consent rights determine who can buy.
Concentration: merchant, vertical, and agent concentration all move price.
Growth and new merchant production: a growing book sells as a business, a flat one sells as a stream.
Contract terms: exclusivity, non-solicits, and residual splits either protect value or leak it.

Portfolio sale or full company sale?

Selling the residual stream is faster and simpler. Selling the company captures value for your brand, your agents, and your growth engine. The right answer depends on your goals, your contracts, and the current buyer appetite. We will tell you which path pays more before you commit to either.

FAQ

ISO and portfolio questions sellers ask

What is my merchant residual portfolio worth?

Residual portfolios are priced as a multiple of monthly residuals, and the multiple moves with attrition, processor, concentration, and growth. Anyone quoting you a multiple before reading your residual statements is guessing. We provide a confidential valuation based on the actual book.

How do I sell my ISO without my agents or processor finding out?

Confidentiality is process design: blind profiles, staged disclosure, NDAs before any identifying detail, and controlling when the processor is approached. This is standard practice in every 733Park engagement.

How long does it take to sell an ISO or portfolio?

Straight portfolio sales can close in 60 to 120 days. Full company sales typically run four to eight months. Preparation before going to market, especially cleaning up contracts and residual reporting, is what shortens the clock.

Should I sell to my processor?

Sometimes the processor is the best buyer, but accepting their first offer without a process almost always leaves money on the table. A competitive process, even a quiet one, is how you find out what the book is actually worth.
