Invoice handoff
How to document extra work before it becomes an invoice dispute.
The final invoice is too late to explain a surprise charge. The better moment is when the extra work comes up, while the customer can still see the condition and approve the cost.
Direct answer
Document extra work before invoicing by recording the site condition, pricing the added labor and materials, getting customer approval, and saving a PDF or text record for the invoice.
01Workflow

02Practical notes
What matters in the field.
Surprise charges create mistrust.
Homeowners are more likely to accept added cost when they understand it before the work starts.
The invoice should be the final record.
Your invoice software can stay the system of record. The approval ticket becomes the evidence behind the invoice line.
Small extra work still needs a trail.
Even a short approval text or one-page PDF can prevent a simple job from turning into a payment argument.
03Checklist
Before you add it to the invoice
Customer has seen the change

04FAQ
Common questions.
Can I just put extra work on the final invoice?
You can, but it is riskier. A customer may see it as a surprise charge. A pre-invoice approval record makes the invoice easier to defend.
Does this replace my invoice software?
No. Use SiteTicket AI as approval backup, then keep invoicing inside your existing system.
