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. Web Designer line items + standard terms
Every web designer invoice in South Dakota should itemize work clearly. Standard web designers use Net 14 terms with a 50% deposit required upfront.
- Design + build — billed by flat.
- Hourly customization — billed by hour (~$95 default).
- Hosting setup — billed by passthrough.
3. Web Designer licensing in South Dakota
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. South Dakota customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
