How do I register a Professional and Commercial Equipment and Supplies Merchant Wholesalers business in the United States?
To register a Professional and Commercial Equipment and Supplies Merchant Wholesalers business, first choose your legal structure: sole proprietorship (simplest, uses SSN), LLC (personal liability protection, files with your Secretary of State), or corporation (Form 1120 or 1120-S).

What does the FTC Mail Order Rule mean for a Professional and Commercial Equipment and Supplies Merchant Wholesalers?
The FTC Mail, Internet, or Telephone Order Merchandise Rule (30-Day Rule) requires a Professional and Commercial Equipment and Supplies Merchant Wholesalers to have a reasonable basis for any shipping time claim (e.g., 'Ships in 2 days'), and if no time is specified, you must ship within 30 days. If you cannot ship on time, you must seek the customer's consent to a revised date or provide a full refund promptly. This applies to all orders placed online, by phone, or by mail. Penalties can exceed $50,000 per violation.
Does a Professional and Commercial Equipment and Supplies Merchant Wholesalers need to accept returns and issue refunds?
There is no federal law requiring retailers to accept returns or offer refunds. However, if you do not accept returns, you must clearly and conspicuously disclose this before purchase (FTC). Some states (e.g., California) require a posted refund policy and allow consumers to cancel certain in-home sales within 3 days. Credit card association rules (Visa/Mastercard) have chargeback policies that effectively require you to have a fair return policy. Clearly post your refund policy at the register and on receipts.
What are the rules for gift cards sold by a Professional and Commercial Equipment and Supplies Merchant Wholesalers?
The federal Credit CARD Act of 2009 sets rules for gift cards, store gift cards, and general-use prepaid cards: funds cannot expire for at least 5 years from the date of purchase or last reload; dormancy/inactivity fees can only be charged after 12 months of inactivity and no more than one fee per month; all fees and expiration dates must be clearly disclosed on the card or packaging. Some states have stronger protections (California prohibits any expiration dates on gift cards).
In which states does a Professional and Commercial Equipment and Supplies Merchant Wholesalers need to collect sales tax?
Under the South Dakota v. Wayfair decision, a Professional and Commercial Equipment and Supplies Merchant Wholesalers must collect sales tax in any state where it has economic nexus — typically $100,000 in gross revenue or 200 separate transactions into the state in the current or previous calendar year. Some states use a higher threshold ($250K-$500K). Marketplace facilitators like Amazon, eBay, and Etsy collect on your behalf in most states. Physical presence (store, office, warehouse, employees) creates nexus immediately in that state. Register through each state's department of revenue or use a sales tax automation service.
