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. Social Media Manager line items + standard terms
Every social media manager invoice in Maryland should itemize work clearly. Standard social media managers use Net 30 terms with a 50% deposit required upfront.
- Monthly retainer — billed by flat.
- Content packages — billed by flat.
- Ad management — % of spend — billed by pct (~$15 default).
- Content shoot day rate — billed by day.
3. Social Media Manager licensing in Maryland
No license required. FTC disclosure rules apply for influencer collaborations.
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%.
