Invoice FAQs

What is an AI invoice generator?▼
An AI invoice generator creates a draft invoice from a plain-English description of the work performed. You describe the job, and the AI drafts line items, quantities, rates, notes, and payment terms for you to review.
Can AI create invoice line items?▼
Yes. LeadDuo AI can draft line items such as labor, parts, service fees, supplies, discounts, and notes based on your job description.
Should I review an AI-generated invoice before sending it?▼
Yes. AI creates a draft. You should review prices, taxes, payment terms, customer details, and due dates before sending.
What kinds of businesses can use an AI invoice generator?▼
Service businesses such as cleaning, HVAC, plumbing, electrical, landscaping, handyman, pest control, and carpet cleaning companies.
Can AI write the customer email too?▼
Yes. LeadDuo AI can draft a professional customer email that summarizes the invoice and payment terms.
Does the AI send invoices automatically?▼
No. You stay in control. AI drafts the invoice, and you choose whether to download or send it.
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.
