FAQ
Frequently asked questions
Can the Front Desk Agent distinguish between a small office and a large industrial facility?
Yes. It uses your client data to recognize client types and service level agreements (SLAs), prioritizing high-value contract customers and emergency calls based on your rules.
Can the Quoting Agent handle multi-unit maintenance contracts?
Yes. You can define contract templates. The agent can take a list of assets from a site survey and generate a comprehensive annual or quarterly maintenance proposal automatically.
How does the system handle after-hours emergency calls?
The agent detects urgent keywords and immediately notifies your on-call technician with all the job details, customer history, and site access information, bypassing the main office.
Does it track refrigerant usage for EPA compliance?
Yes. Techs can log refrigerant type and amount used on each job via the mobile app, and the system maintains a digital log for easy compliance reporting.
Can I set different pricing for contract vs. non-contract clients?
Yes. The system supports multiple price books. The Quoting Agent automatically applies the correct labor rates and material markups based on the client's contract status.
Does it sync with my existing accounting software?
Yes, we offer integrations with QuickBooks Online and other major accounting platforms to sync invoices and payments, eliminating double entry.
Can my techs see service history in the field?
Yes. The mobile app gives techs access to the full service history for each piece of equipment, including past repairs, notes, and photos, right from their phone or tablet.
