How Relay fits your workday
2 / 3
Plan the visit with the team
Assign a technician and time window, review availability, and keep the approved scope with the scheduled work.
3 / 3
Record what happened on site
Configure a service checklist and capture notes and private photos. Leave a work summary the office can use when a return visit is needed.
Put it to the test before you subscribe
Use one service call with an equipment record. Ask a second team member to find the prior visit, current scope, and follow-up owner without asking the original technician.
Questions before getting started
Does Relay diagnose equipment faults?
No. Relay organizes records and work. Your qualified technicians make diagnostic, safety, and repair decisions; service notes and checklists do not replace their judgment.
Can my team use it on a phone?
Relay is a browser-based workspace with mobile layouts for job details, notes, checklists, and photo evidence. No separate app installation is required.
Does Relay handle customer payments?
Relay keeps receipt records and manual settlement history. It does not charge your customers or move money. Keep your payment processor and accounting process in place.
