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. Personal Trainer line items + standard terms
Every personal trainer invoice in New Jersey should itemize work clearly. Standard personal trainers use Net 0 terms with no deposit required.
- Single session — billed by session (~$75 default).
- 10-pack package — billed by flat (~$650 default).
- Monthly programming — billed by flat (~$199 default).
- Online coaching — billed by flat (~$149 default).
3. Personal Trainer licensing in New Jersey
No state license. National certification (NASM, ACE, NSCA) expected. CPR/AED required by most gyms and insurers.
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%.
