Field Service Invoicing Software
Invoice the moment the work is done. Build and send an invoice from your phone at the job site, capture proof of service, and collect payment before you leave.
No credit card required to start · Works on any phone
Field service work doesn't happen at a desk, so your invoicing shouldn't either. Costryx Pay runs in any phone browser, so you can build an itemized invoice in the customer's driveway, send it on the spot, and watch it get paid before you drive to the next call.
Pair invoicing with Costryx Pay's field forms to capture GPS-stamped service records, photos, and on-screen signatures. Now every invoice is backed by proof of when, where, and what was done — the kind of paper trail that ends payment disputes before they start.
What you get
Invoice from any phone
No app install required. Open Costryx Pay in a mobile browser, build the invoice, and send it while you're still on site.
Proof of service attached
Capture GPS coordinates, timestamps, photos, and digital signatures on companion field forms so every bill is backed by evidence.
On-site card payment
Hand the client a Pay Now link and collect a card payment before you leave. Funds settle to your bank through Stripe.
Reusable clients & defaults
Save customers and default terms once. Recurring service calls take seconds to invoice because the details are already there.
