1. Maryland-specific invoice requirements
- Sales tax line: 6.00% state rate. Most services rendered in Maryland are exempt from sales tax — but materials, parts, and tangible goods are not. State 6%; uniform statewide. No local sales tax.
- Late-fee cap: Maryland statute Md. Com. Law §12-103 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.
- Written contract required: Maryland requires a signed agreement for any job over $1,000. Reference the contract number on the invoice.
- Right-to-cancel notice: Customers in Maryland get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Chiropractor line items + standard terms
Every chiropractor invoice in Maryland should itemize work clearly. Standard chiropractors use Net 30 terms with no deposit required.
- Adjustment — billed by session (~$75 default).
- New patient exam — billed by flat (~$165 default).
- X-ray — billed by flat.
- Decompression / therapy — billed by session.
3. Chiropractor licensing in Maryland
State DC license required. CMS HIPAA rules apply for Medicare/Medicaid claims.
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. Maryland customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
