Census does not publish a separate category for payment processing and merchant services providers; these figures use NAICS 522320, Financial Transactions Processing, Reserve, and Clearinghouse Activities, the closest official industry. The count moved −11.8% between 2022 and 2023 in New Hampshire, against −6.4% nationally, so the field is not growing faster than the national market.

The industry is concentrated in Hillsborough County and Rockingham County, which together hold 46.7% of the state's establishments. For a firm selling into the same market, that concentration also shows where buyers already have the most vendors to choose from, and where a researched, specific first email matters most.

Owners and general managers decide at most small businesses. At multi-location or larger businesses, the CFO, controller or operations director is involved.

When are businesses open to changing payment processors?

When opening new locations, adding online sales, replacing point-of-sale systems or changing ownership. These moments create a natural review of the payment setup.

Is cold email legal in the United States?

Yes. The federal CAN-SPAM Act permits commercial email to business contacts without prior consent, provided the message identifies the sender accurately, uses a truthful subject line, includes a valid physical postal address and a working opt-out, and honours opt-out requests promptly. CAN-SPAM applies in every state and preempts most state commercial email laws, except provisions aimed at falsity or deception. This is general information, not legal advice.
