Adding Tap to Pay on iPhone to a field service app

Why field teams want it

Card-present payment at the job site reduces invoices that sit unpaid. Technicians finish the commercial moment while the customer still cares. Owners see fewer collections loops.

Product requirements before SDK talk

Define who can take payment. Define what happens when the network drops. Define refunds and partial payments. Define whether tips are allowed. Define how payments attach to jobs and invoices in the office dashboard.

Mobile realities

Tap to Pay flows must feel fast with gloves, bright sunlight, and impatient customers. Error messages must be plain. Receipt delivery by email or SMS should be one tap. Training materials should live in the app.

Architecture notes

Keep payment processor secrets off the device. Use processor SDKs as documented. Store only what you must. Make webhook handling idempotent. Reconcile device payments with office invoices nightly if needed.

Rollout plan

Pilot with one crew. Measure failed payments and time-to-close. Expand location by location. Keep a fallback invoice path so a payment outage does not strand the technician.

Compliance and trust

Follow the processor and Apple program requirements. Do not invent PCI shortcuts. Tell customers what they are paying for on screen before they tap.

How we approach it

We have shipped field-capable mobile apps with modern card and wallet payments. Public naming of specific processor setups depends on client permission. If you need Tap to Pay in a custom field app, bring your invoice flow to a discovery call.
