How to Start a Reselling Business with $100
You don't need thousands of dollars to start reselling. Some of the most successful full-time resellers began with less than $100 in inventory — sometimes with items sitting in their own closet. The key isn't how much capital you start with; it's how intelligently you deploy it.
In this guide, we'll walk through exactly how to turn $100 into a functioning reselling business, step by step. We'll cover where to source, which platforms to sell on, how to price, and how to reinvest profits to scale — with real math at every step.
Why $100 Is Enough to Start
Here's the reality: reselling has the lowest barrier to entry of any business model. You don't need a website, a warehouse, employees, or even a business license to get started (though you should look into one as you grow). Here's why $100 works:
- Thrift stores sell items for $2-10 that resell for $20-100+
- Garage sales are even cheaper — most items are $0.50-5
- Your own closet is free inventory — clothes, shoes, electronics, books you already own
- Listing is free on most platforms (eBay gives 250 free listings/month)
- Shipping supplies can be gotten free (USPS Priority boxes, Amazon boxes, newspaper for packing)
With $100, you can realistically buy 15-30 items that sell for $15-50 each. That's $225-$1,500 in potential revenue from your first round of sourcing. Even after fees and shipping, you're looking at 2-5x returns.
Step 1: Start with What You Already Own ($0)
Before spending a dime, look around your home. Most people have $200-500+ worth of resellable items they don't use:
- Clothing: Brand-name items you don't wear (Nike, Lululemon, Patagonia, North Face)
- Shoes: Especially Nike, Jordan, New Balance, Birkenstock
- Electronics: Old phones, tablets, game consoles, headphones
- Books: Textbooks, first editions, popular titles
- Video games: Retro games can be surprisingly valuable
- Kitchen items: Le Creuset, KitchenAid, Vitamix
- Toys: LEGO sets, Barbie, vintage toys
List these items first. They cost you nothing, so every dollar is profit (minus platform fees and shipping). This is how you learn the process — photographing, listing, pricing, shipping — without any financial risk.
Step 2: Choose Your Starting Platform
Don't try to list on every platform at once. Start with one and learn it well. Here's how to pick:
eBay — Best All-Around Starting Platform
- 250 free listings per month
- 130M+ active buyers — anything sells here
- 13.25% + $0.30 per sale
- Best for: electronics, collectibles, vintage, shoes, general items
Poshmark — Best for Clothing
- Free to list, no limits
- 20% commission (or $2.95 under $15)
- Prepaid shipping labels included ($7.97)
- Best for: women's fashion, designer items, shoes
Mercari — Best for Quick Sales
- Free to list
- 10% + payment processing
- Smart pricing feature auto-drops prices
- Best for: general items, electronics, home goods
Whatnot — Best for Live Selling
- 9.5% commission (drops to 8% with volume)
- Live auction format creates urgency
- Best for: trading cards, sneakers, coins, vintage, collectibles
Our recommendation for $100 beginners: Start with eBay. It has the broadest audience, lowest entry barrier, and you'll learn universal reselling skills (photography, pricing, shipping) that transfer to every other platform.
Step 3: Allocate Your $100 Budget
Here's how we'd split $100 for maximum ROI:
- $70 — Inventory: This is your money maker. Allocate the majority here.
- $15 — Shipping supplies: Poly mailers ($5 for 100), tape ($3), bubble wrap ($7)
- $10 — Scale: A basic kitchen/postal scale for accurate shipping weights
- $5 — Contingency: Extra packing tape, labels, etc.
Note: You can reduce shipping supply costs to near-zero by reusing Amazon boxes, using newspaper for padding, and getting free Priority Mail boxes from USPS.com. That gives you $85+ for inventory.
Step 4: Source Your First Inventory ($70)
With $70, you want items with the highest possible ROI. Here's where to go:
Thrift Stores (Best for Beginners)
Goodwill, Salvation Army, Savers, local thrift shops. Budget: $30-40
- Look for: brand-name clothing (Polo, Tommy, Nike, Carhartt), vintage tees, leather goods, cashmere sweaters
- Average cost: $3-8 per item
- Average resale: $15-40 per item
- Expected ROI: 3-8x
- Pro tip: Go on half-off days (most Goodwills have colored tag sales)
Garage Sales / Estate Sales
Saturday morning runs. Budget: $20-30
- Best finds: vintage items, electronics, tools, books, vinyl records
- Average cost: $0.50-5 per item
- Average resale: $10-50+
- Expected ROI: 5-20x
- Pro tip: Go at the end of the day and offer to buy remaining items in bulk for cheap
Facebook Marketplace (Free Stuff)
Search "free" and "moving sale" in your area. Budget: $0-10 (gas money)
- People give away furniture, electronics, clothes when moving
- Pick up free items, clean them up, resell for profit
- 100% profit margin (minus platform fees)
What to Buy: The $100 Starter Kit
Here's a realistic haul from one Saturday of sourcing:
- Carhartt jacket — $8 thrift → sells for $35-50

Good photos are the #1 factor in getting sales. You don't need a fancy camera — your phone works fine.
Photography Tips (Free Setup)
- Natural light near a window — the best free lighting
- White or clean background (a $1 white poster board works)
- Take 5-8 photos per item: front, back, tag/label, close-up details, any flaws
- Clean items first — lint roll clothing, wipe down electronics
- Use Portrait mode for depth-of-field effect on shoes/small items
Listing Tips
- Title: Use all 80 characters on eBay. Include brand, model, size, color, condition
- Description: Measurements for clothing, specs for electronics, honest condition notes
- Price: Check sold comps on eBay (filter by "Sold items") — price 5-10% below average for fast sales
- Shipping: Offer free shipping (build it into the price) — items with free shipping sell 20%+ faster
Step 6: Price for Profit
Pricing is where most beginners leave money on the table — either pricing too low (leaving profit behind) or too high (items sit forever).
The Comp Research Method
- Search the exact item on eBay
- Filter by "Sold Items" to see what it actually sold for (not what people are asking)
- Look at the last 10-20 sales
- Price your item at or slightly below the median sold price
- Account for condition — mint condition items sell for 20-30% more than good condition
Quick Pricing Formula
Minimum price = (Cost × 3) + Shipping + Platform Fee
If you paid $5, you need to sell for at least $15 + shipping + fees to hit a 3x return. On eBay at $25 shipped, your take-home after 13.25% fee is ~$21.44. Minus $5 cost and ~$5 shipping materials = $11.44 profit per item.
Multiply that across 10-15 items from your $70 haul and you're looking at $115-170 profit from $70 invested. That's how you double your money in the first round.
Step 7: Ship Smart, Ship Cheap
Shipping costs can eat into your profits if you're not careful. Here's how to keep costs down:
- USPS Priority Mail: Free boxes from USPS.com, flat rate options ($9.65-$22.10)
- USPS Ground Advantage: Cheapest for packages under 1 lb ($4-5)
- Pirate Ship: Free account, USPS Cubic pricing saves 25-35% on small heavy items
- Poly mailers: $0.05 each for soft goods — way cheaper than boxes
- Reuse packaging: Amazon boxes, newspaper padding — free and eco-friendly
Shipping Cost by Weight (Approximate)
- Under 4 oz (t-shirt in poly mailer): $3.50-4.00
- 8 oz - 1 lb (jeans, small electronics): $5.00-6.50
- 1-3 lbs (shoes, jackets): $7.00-9.50
- 3-5 lbs (gaming console, heavy items): $9.50-14.00
Step 8: Reinvest and Scale
This is where the magic happens. When your first batch sells, reinvest 70-80% of your profits back into inventory. Here's how the math works over 90 days:
The $100 to $1,000 Roadmap
Month 1:
- Start: $100
- Buy 15 items → sell 10-12 in first month
- Revenue: ~$300
- Profit after fees/shipping/COGS: ~$150
- Reinvest $120 → keep $30
- End of Month 1: ~$120 inventory budget + unsold items
Month 2:
- Buy 20-25 items with $120 budget
- Sell 15-20 items (including Month 1 leftovers)
- Revenue: ~$500
- Profit: ~$250
- Reinvest $200 → keep $50
- End of Month 2: ~$200 inventory budget + growing reputation
Month 3:
- Buy 30-40 items with $200 budget
- Sell 25-30 items
- Revenue: ~$900
- Profit: ~$450
- You now have a legit reselling business generating $400+/month
- End of Month 3: $350+ inventory budget, 50+ feedback score on eBay

Once you're comfortable on your first platform, cross-list to multiply your exposure:
- Month 1: Master one platform (eBay recommended)
- Month 2: Add Mercari or Poshmark for clothing items
- Month 3: Add Whatnot for live selling if you have collectibles, cards, or sneakers
- Month 4+: Cross-list everything on 3-5 platforms simultaneously
Cross-listing increases your sell-through rate by 2-5x because you're exposing your items to different buyer pools. An item that sits for 30 days on eBay might sell in 2 days on Mercari (or vice versa).
Step 10: Build Systems Early
Even with a $100 start, build good habits from day one:
- Track every purchase and sale in a spreadsheet (cost, platform, sale price, fees, shipping, profit)
- Take photos immediately after sourcing — don't let items pile up
- List within 24 hours of purchasing — inventory sitting = money sleeping
- Designate a space for inventory, even if it's a closet shelf or corner of a room
- Ship same-day or next-day — fast shipping = good reviews = more sales
Common Mistakes to Avoid
- Buying what you like instead of what sells: Use sold comp data, not your gut feeling
- Spending too much per item early on: Keep your average cost under $7-8 when starting with $100
- Not accounting for fees: A $20 sale on eBay is really $16.85 after fees. Know your real margins.
- Hoarding unsold inventory: If it hasn't sold in 30 days, lower the price. Cash flow beats perfect margins.
- Ignoring shipping costs: A $15 profit item that costs $12 to ship is only a $3 win. Factor shipping into every buying decision.
- Skipping photos: Bad photos = no sales, period. Spend 2-3 minutes per item getting good shots.
What $100 Resellers Are Making in 2026
Based on reseller community data and our own tracking:
- Conservative (part-time, 5 hrs/week): $300-600/month by month 3
- Active (10-15 hrs/week): $800-1,500/month by month 3
- Aggressive (20+ hrs/week): $1,500-3,000/month by month 3
The differentiator isn't money — it's time and knowledge. Learning to spot valuable items quickly, price accurately, and ship efficiently is what separates $500/month resellers from $5,000/month resellers.
The Bottom Line
Starting a reselling business with $100 isn't just possible — it's how most successful resellers began. The low barrier to entry means you can test, learn, and iterate without significant financial risk. The key is:
- Start with items you already own (free inventory)
- Source smart — thrift stores, garage sales, and free pickups
- Price using real sold comp data, not guesses
- Reinvest 70-80% of profits to compound growth
- Build systems early so you can scale without chaos
In 90 days, that $100 can realistically become a $500+/month side hustle. In 6 months, with consistent effort, you could be generating $1,000-2,000/month. And a year from now? That's when things get really interesting.
