1. Missouri-specific invoice requirements
- Sales tax line: 4.23% state rate. Most services rendered in Missouri are exempt from sales tax — but materials, parts, and tangible goods are not. State 4.225%; combined 7-10% in metros.
- Late-fee cap: Missouri statute Mo. Rev. Stat. §408.020 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 Missouri get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Virtual Assistant line items + standard terms
Every virtual assistant invoice in Missouri should itemize work clearly. Standard virtual assistants use Net 7 terms with no deposit required.
- Hourly support — billed by hour (~$45 default).
- Retainer (monthly hours) — billed by flat.
3. Virtual Assistant licensing in Missouri
No license required.
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. Missouri customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
