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. Financial Advisor line items + standard terms
Every financial advisor invoice in Missouri should itemize work clearly. Standard financial advisors use Net 30 terms with no deposit required.
- Plan preparation flat fee — billed by flat.
- Hourly advisory — billed by hour (~$295 default).
- AUM fee — annual % — billed by pct (~$1 default).
- Tax-prep coordination — billed by flat.
3. Financial Advisor licensing in Missouri
Series 65 / 66 + state RIA registration required for fee-only advisors. CFP / CFA designations are industry-standard.
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%.
