Frequently Asked Questions

What should a plumbing invoice include?
A plumbing invoice should itemize the service call or trip charge, labor hours, specific parts used (fittings, pipes, valves, fixtures) with part numbers, any permits pulled, camera inspection fees, and emergency/after-hours surcharges. For water heater installs, include the unit model number, haul-away fee for the old unit, and any code-compliance work.
How should I price emergency plumbing calls on an invoice?
Emergency and after-hours plumbing calls typically carry a premium of 1.5×–2× your standard rate. List the emergency surcharge as a separate line item (e.g., 'After-Hours Emergency Fee: $150') so customers see the base service cost vs. the urgency premium. This reduces disputes and sets expectations for future calls.
Should plumbing invoices include permit fees?
Yes, if you pulled permits for the work (required for water heater installs, re-pipes, sewer line work in most jurisdictions), list the permit cost as a separate line item. Pass it through at cost — customers understand it's a municipal requirement. Include the permit number on the invoice for their records.

Invoice FAQs

What should a professional invoice include?▼
A professional invoice should include: your company name and contact info, the customer name and service address, invoice number, service date, a line-item breakdown of services performed, subtotal, tax if applicable, discount if any, total due, and payment terms.
Should service businesses charge sales tax?▼
It depends on your state and local tax rules. Some states tax certain services, others do not. Residential and commercial services may be taxed differently. Check with your local tax authority or accountant.
How should I number my invoices?▼
Use a sequential numbering system like INV-001, INV-002, or include the year and month (2026-05-001). Consistent numbering helps with bookkeeping, tax filing, and payment tracking.
What payment terms should I use?▼
For one-time residential jobs, 'Due on Receipt' or 'Due on Completion' is standard. For recurring clients, consider billing at the start of each month. For commercial accounts, Net-15 or Net-30 is common but should be in a written agreement.
How do I get paid faster?▼
Accept multiple payment methods (card, Zelle, Venmo, check). Send invoices immediately after service — not days later. Use clear due dates and follow up promptly on overdue invoices. Offering a small early-payment discount (e.g., 2% off if paid within 5 days) can also help.
Can I use this invoice generator for free?▼
Yes. You can create and download up to 2 invoices per month on the free plan. All 4 templates, accent colors, and clone features are included. Upgrade to Lite ($5/mo) for 25 invoices or Plus ($10/mo) for 75 invoices with branding removal.
What industries does this support?▼
The invoice generator includes preset line items for cleaning, HVAC, plumbing, electrical, landscaping, painting, handyman, pest control, carpet cleaning, and general services. Select your industry from the dropdown to see relevant presets.
