The procedure, step by step
- Invoice promptly — Generate the invoice from the completed work order the same day or next business day — speed of billing drives speed of payment.
- Match invoice to approved scope — Bill the approved estimate plus any signed change orders only — no surprise line items.
- Itemize clearly — Show labor, materials, fees, and applicable tax so the customer can reconcile it against the estimate.
- State payment terms — Include due date, accepted methods, and any late terms on the invoice.
- Collect at the agreed point — Collect on completion or per the agreed terms; offer convenient payment methods to reduce friction.
- Send a receipt — Provide a receipt immediately on payment and record it against the job.
- Follow up on overdue — Run a consistent reminder sequence on unpaid invoices instead of letting them age silently.

This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a Electrical business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan. Open the tool above to print it, toggle ink-saver, or (with a free ToolFluency Business account) edit it to match your own workflow.

Frequently asked questions
How fast should I invoice after a job?
Same day or next business day. Faster invoicing reliably leads to faster payment and healthier cash flow, which matters most for small shops with thin reserves. Build it into job closeout so it never slips.
How should sales tax appear on the invoice?
Itemize applicable tax as a clear line so the customer can reconcile the invoice against the estimate. The specific tax treatment for your jurisdiction defers to your accountant and tax authority, not this SOP.
