1. Oklahoma-specific invoice requirements
- Sales tax line: 4.50% state rate. Most services rendered in Oklahoma are exempt from sales tax — but materials, parts, and tangible goods are not. State 4.5%; combined commonly 8-10%.
- Late-fee cap: Oklahoma statute Okla. Stat. tit. 15, §266 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 Oklahoma get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Virtual Assistant line items + standard terms

- Hourly support — billed by hour (~$45 default).

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. Oklahoma customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
