From industry leader Square to more vertically oriented players, companies operating as payment facilitators announced plans to expand through acquisition, new products, and partnerships over the past week.

Providing developers with direct access to its hardware for the first time, Square introduced Square Reader SDK, a toolkit to allow developers to enhance their customer offerings with a custom, in-person checkout experience.

“Ultimately, developers will use this SDK to help new types of businesses take payments with Square for the first time, help grow sales for existing sellers, and build more powerful and compelling experiences for both buyers and sellers,” the company’s developer platform lead, Carl Perry, said in a blog post.

RealPage, a software provider and PF serving the real estate industry, announced that it had acquired LeaseLabs, which provides digital marketing services and software geared to multifamily housing. The company plans to use the acquisition to extend its own marketing platform.

The company also announced its quarterly earnings last week, reporting a 34% year-over-year increase in total revenue to $216.3 million.

PayStand, a B2B payments platform and PF, announced an integration with leading small business bookkeeping platform Xero.

A plug-in available on the Xero marketplace would enable users of Xero’s platform to “accept bank (ACH, Smart ACH/eCheck) and card (debit, credit) payments directly in sales orders and invoices. This dramatically speeds up time to cash, automates accounting processes and lowers transaction costs,” the company said in a press release.

And USA Technologies, a PF serving the self-serve retail market, announced a new relationship with Pepsi Bottling Ventures. The Pepsi bottler plans to deploy the company’s ePort cashless payment system on 13,000 of its machines reaching consumers in North Carolina, South Carolina, Virginia, Maryland, and Delaware.
