1. New Jersey-specific invoice requirements
- Sales tax line: 6.63% state rate. Most services rendered in New Jersey are exempt from sales tax — but materials, parts, and tangible goods are not. State 6.625%; uniform with limited Urban Enterprise Zones at 3.3125%.
- Late-fee cap: New Jersey statute N.J. Stat. §31:1-1 caps interest on unpaid invoices at 1.5% per month. Spell out the rate in writing on every invoice and in your contract — courts won't enforce undisclosed fees.
- Written contract required: New Jersey requires a signed agreement for any job over $500. Reference the contract number on the invoice.
- Right-to-cancel notice: Customers in New Jersey get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Welder line items + standard terms
Every welder invoice in New Jersey should itemize work clearly. Standard welders use Net 14 terms with a 25% deposit required upfront.
- Labor — billed by hour (~$95 default).
- Filler material — billed by itemized.
- Mobile setup fee — billed by flat (~$150 default).
- Certification surcharge — billed by pct.
3. Welder licensing in New Jersey
AWS or state-specific certification required for structural and pressure work. Mobile welders need contractor license in many states for jobs over a threshold.
4. Send and follow up
Send the invoice the same day work completes. Use software that records open events and offers a one-click online payment so you don't need to chase a check by mail. New Jersey customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
