1. Arkansas-specific invoice requirements
- Sales tax line: 6.50% state rate. Most services rendered in Arkansas are exempt from sales tax — but materials, parts, and tangible goods are not. State 6.5%; combined often 9-11%.
- Late-fee cap: Arkansas statute Ark. Const. art. 19, §13 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.
- Right-to-cancel notice: Customers in Arkansas 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 Arkansas 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 Arkansas
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. Arkansas customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
