What it costs to sell these ideas in 2026, and the rules to know
Any of the ideas above can sell. Your profit depends on where you list and which rules apply to you. Here is what the two largest US marketplaces for handmade, vintage and resale goods charge, as published on their own pages in October 2026:
| Fee | Etsy | eBay (most categories, no Store) |
|---|---|---|
| Listing fee | $0.20 per listing, active 4 months or until sold | 250 free listings per month, then $0.35 each |
| Sale fee | 6.5% transaction fee on the price including shipping | 13.6% final value fee on the total sale (up to $7,500 per item) |
| Payment / order fee | 3% + $0.25 payment processing (US) | $0.30 per order up to $10, $0.40 above $10 |
| Other | 15% Offsite Ads fee when a sale comes from Etsy's ads, 2.5% currency conversion | Store subscribers pay 12.7% instead of 13.6% (on the sale up to $2,500 per item) in most categories |
| Example: $50 sale | $0.20 + $3.25 + $1.75 = $5.20 (about 10%) | $6.80 + $0.40 = $7.20 (about 14%) |
Price your products with these fees included. On a $15 bath bomb or a $20 jar of jam, fees take a bigger share of a small margin than they do on a $300 piece of upcycled furniture. Local classifieds work differently: buyers usually pay cash or by bank transfer when they collect, so selling fees are low or zero. The trade-off is less built-in buyer protection.
US rules that changed after this list was written
- Seller verification (INFORM Consumers Act). Since June 27, 2023, US online marketplaces must verify "high-volume" sellers. That means 200 or more sales of new or unused products and $5,000 or more in revenue in any continuous 12 months within the past 24 months. Within 10 days of you crossing the threshold, the marketplace must collect your bank account, tax ID and contact details. Above $20,000 a year, your name, address and contact details are shown to buyers. Home-based sellers can show just their state and country. Source: the FTC's guide to the act.
- Tax reporting (Form 1099-K). The IRS page last updated June 28, 2026 says payment apps and online marketplaces must file a 1099-K when your payments exceed $20,000 in more than 200 transactions. If you receive less, you still owe tax on any profit.
- Skincare and bath products (MoCRA). Under the Modernization of Cosmetics Regulation Act, cosmetic makers must register facilities, list products and their ingredients, keep safety records, and report serious adverse events to the FDA within 15 business days. Some small businesses are exempt from registration and listing. The exemption doesn't cover products that contact the mucous membrane of the eye, are injected or used internally, or change your appearance for more than 24 hours. Check before you sell scrubs, body butters or bath bombs.
- Homemade food. Gourmet jams, baked goods and coffee blends fall under state or national food-safety rules, which vary a lot. Check your local rules for home-made food (in the US, state 'cottage food' laws) before listing, and check each marketplace's food policy.
Marketplace or your own site?
Start on a big marketplace if you need buyers on day one and your margins can absorb a 10-14% fee. Consider your own niche site once you have a loyal audience or a whole category to yourself, such as local vintage furniture, pet products in your city or a coffee-roaster directory. There you keep the customer relationship and set the rules. Hosted builders such as Yclas let you launch a niche classifieds marketplace without writing code.
Summary
Marketplace and classified websites provide an excellent platform to turn your passion and creativity into a profitable venture. Whether it's crafting handmade jewelry, selling vintage clothing, or offering personalized services, the key lies in identifying unique ideas that cater to specific market demands.
