- 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.

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%.
