Point of sale (POS) is taking on a larger role across industries, from retail to restaurants to healthcare. What used to function as a checkout tool now sits at the center of operations, data flow, and customer engagement.

As organizations modernize, the scope of POS field service work is expanding. Here are three trends shaping deployments and demand.

1- POS is becoming mission-critical infrastructure

Organizations depend on POS systems to keep operations running. As equipment ages and support contracts expire, organizations are speeding up replacement cycles.

Field Nation data points to a 16.3 percent increase in point-of-sale work year-over-year, signaling widespread modernization that goes beyond routine maintenance.

This aligns with broader market growth. According to industry estimates, the global point-of-sale market is valued at more than $44.6 billion in 2026 and is expected to grow at 15.3% annually through 2034.

Modern POS systems support critical operations such as inventory lookups, returns processing, and real-time reporting. When terminals or peripherals age out of support or require updates, organizations see immediate impacts on reliability and performance. For field service teams, this means steady demand for installations, refreshes, and site assessments to keep systems running.

2- Systems are connecting to the rest of the business

POS no longer operates as a standalone checkout tool. Across retail, restaurant, and other service environments, deployments now tie into inventory visibility, digital ordering, loyalty platforms, and reporting systems.

As more platforms exchange information, every connection point becomes critical. A device can power on and still fail if data doesn’t move correctly between systems.

For field service teams, success requires more than installing hardware or activating software. Technicians validate network readiness, confirm peripherals communicate properly, and resolve interoperability issues so transactions run without interruption.

3. Checkout moves beyond the counter

The way customers pay continues to expand beyond the traditional checkout lane.

Mobile POS isn’t new. But the number of devices per location is growing, and so are the use cases such as assisted selling, line busting, and curbside checkout. The global mobile POS market is valued at $20.6 billion in 2026 and is projected to reach $92.7 billion by 2034, growing at over 20% annually.

Beyond payments, mobile devices enable flexibility in how and where transactions occur, including pop-ups, smaller footprints, and anywhere checkout experiences. For field service teams, mobile POS requires different installation and maintenance practices than fixed terminals, including wireless network assessment, peripheral pairing, and device lifecycle management.

Planning for what comes next

The role of POS has expanded, and so has the field service work required to support it. Service organizations that understand how POS connects to site infrastructure—and how mobile changes scope of work—can stay ahead of the curve.
