1. Connecticut-specific invoice requirements
- Sales tax line: 6.35% state rate. Services billed to CT customers must include sales tax. Many services taxable (e.g., computer/data, repair, advertising). Combined uniform 6.35%.
- Late-fee cap: Connecticut statute Conn. Gen. Stat. §37-3a 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: Connecticut requires a signed agreement for any job over $200. Reference the contract number on the invoice.
- Right-to-cancel notice: Customers in Connecticut get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Management Consultant line items + standard terms
Every management consultant invoice in Connecticut should itemize work clearly. Standard management consultants use Net 30 terms with a 33% deposit required upfront.
- Project fee — billed by flat.
- Hourly billing — billed by hour (~$295 default).
- Daily rate — billed by day (~$2400 default).

3. Management Consultant licensing in Connecticut
No license required for general management consulting. State CPA / PE rules apply if you sign opinions or stamp work.
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. Connecticut customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
