Old process
- Scope agreed verbally; final bill disputed when price changed
- Technicians carried paper authorization forms
- Change orders on site had no signed record before extra work
- Chargebacks lacked signed scope evidence
With WoltSign
- Service agreement template with scope, price, and customer signature
- Link sent by text before arrival; customer signs on phone
- Change order template for on-site scope increases
- Technician signs on tablet when customer is present
Field service work authorization e-signature captures scope and price before an HVAC technician starts work. An 8-tech company needs a signed record when the final bill differs from the verbal estimate. Without it, disputed invoices become routine.
Why home services teams need HVAC service agreement digital signing
Plumbing, electrical, and cleaning companies share the same pattern: authorize scope before work, re-authorize when scope changes on site. Work order e-signature on mobile keeps the record with the job.

FAQ
Frequently asked questions
Short answers to the questions teams ask most often about this topic.
Can the customer sign while the technician is physically present?
Yes. The technician opens the signing link on the customer phone or on a tablet. The customer signs in person without needing email.
Can I attach a photo of the issue to the work authorization?
Not directly from the signing flow. WoltSign Attachment field allows the signer to upload a file. A technician photo would require attaching to the envelope in the Documents step before sending, or a separate workflow.
Does a signed service agreement protect against chargebacks?
A signed authorization showing the customer agreed to scope and price is evidence of consent. Whether it resolves a specific chargeback depends on your payment processor policies and the circumstances.
