Client contracts
- Sign contracts in the LLC's name, and sign as a member or manager — not personally — to protect your liability shield.
- Cover scope, deliverables, fees, payment terms, late fees, and who owns the work product (intellectual property).
- Include limitation of liability, confidentiality, termination, and how disputes will be resolved.
- Licensed professions need a license from the Delaware Division of Professional Regulation or the relevant board.
Professional insurance
- Professional liability (errors and omissions) covers claims that your work or advice caused a client financial loss. Many clients require it.
- General liability covers injuries or property damage, such as at a client's office.
- Cyber liability matters if you handle client data or systems.
- Workers' comp is required once you have employees.
Invoicing
- Don't add sales tax — Delaware has none.
- Your business pays gross receipts tax on its total receipts, with a monthly exclusion.
- Renew your Delaware business license every year.
- If your LLC is formed in Delaware but you work in another state, that state's taxes and registration rules apply too.
- Put your LLC name, invoice number, dates, services, amounts, and any sales tax (as a separate line) on each invoice.
- Keep invoices and tax records organized — states can audit several years back.
These are Delaware state and federal requirements. Cities and counties often add their own. Requirements and fees change — confirm with the agency before you apply. This is general information, not legal or tax advice.
