1. South Dakota-specific invoice requirements
- Sales tax line: 4.20% state rate. Services billed to SD customers must include sales tax. State 4.2%; applies broadly to services. Combined commonly 6-7%.
- Late-fee cap: South Dakota statute S.D. Codified Laws §54-3-4 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 South Dakota get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Event Planner line items + standard terms
Every event planner invoice in South Dakota should itemize work clearly. Standard event planners use Net 30 terms with a 50% deposit required upfront.
- Planning package — billed by flat.
- Day-of coordination — billed by flat.
- Hourly consulting — billed by hour (~$125 default).
- Vendor management — % of spend — billed by pct (~$15 default).
3. Event Planner licensing in South Dakota
No license required. Liability insurance and venue COI requirements are 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. South Dakota customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
