How to start reselling (and whether it’s for you)
Reselling is one of the few businesses you can run on your own schedule with zero upfront capital. But before you spend a single dollar on inventory, start with what is already in your house.
The biggest appeal of reselling isn't hype or secret clearance hacks. It’s convenience. You work when you want: list two items from the sofa on a Tuesday evening, pack three parcels while listening to a podcast on a Saturday morning, and drop them in the postal bin on your daily commute. There are no set shifts, no bosses, and no leases.
Yet the most common trap beginners fall into is spending hundreds of dollars at thrift stores or liquidation pallets on their first weekend. They end up with boxes of unsold goods cluttering their hallway and feel burnt out before their first payout arrives.
Start with what you already own
Almost every home has hundreds or thousands of dollars of idle value tucked into closets, garages, and kitchen cabinets: jacket sizes you no longer wear, video games finished years ago, old tablets, power tools, or unused cookware.
Selling your own personal items changes the initial equation entirely:
- Zero upfront cash risk: your inventory cost is effectively zero.
- Only time invested: you only invest hours taking photos, writing descriptions, and learning the apps.
- Low-stakes practice: if an item takes two months to sell, you aren’t losing sleep over tied-up capital.
Get a hang of the platforms
Don’t try to master every marketplace at once. Pick one or two that match the items you found in your house:
eBay
Best for: Niche, tech, collectibles, replacement parts
Unmatched global audience. You can sell almost anything, but you need to know how to calculate shipping weights and factor in 13–15% category fees.
Poshmark
Best for: Clothing, shoes, accessories, boutique bags
Simplified flat-rate shipping label paid by the buyer. Highly social with sharing and offers, with a flat 20% commission on sales over $15.
Mercari
Best for: Household goods, video games, small toys
Very fast to list directly from a smartphone. Good middle ground for casual decluttering and medium-sized items.
Facebook Marketplace
Best for: Bulky furniture, heavy tools, local pickup
Zero shipping hassle and no commission when meeting locally for cash. Requires filtering flakey messages and coordinating meetups.
Taxes on personal and household items
One common worry when starting out is taxes. If you bought a winter jacket three years ago for $150 and sell it today on eBay for $40, you did not make a profit. You took a personal loss.
Under general tax guidelines (such as IRS rules in the US), selling used personal possessions for less than what you originally paid for them does not generate taxable income. Even if a marketplace sends you a Form 1099-K because you crossed reporting thresholds, having a clear record showing what the item originally was and that it sold at a loss helps report it cleanly.
Note: We make software, not tax advice. Tax laws vary by jurisdiction and change frequently. Always confirm how personal sales and Form 1099-K reporting apply to your individual tax return with a licensed CPA or accountant.
Find your niche before you source
Selling 15 or 20 household items teaches you something critical: what you actually enjoy handling.
Did you find measuring chest widths and checking clothing seams tedious? Then don’t start a vintage clothing business. Did you enjoy cleaning an old camera, checking the shutter, and researching completed listings? Or did you prefer listing small boxed video games that slide into a bubble mailer in thirty seconds?
Once you discover what items fit your patience, space, and interests, that is when you begin sourcing. You can hit thrift stores, garage sales, church bazaars, or estate sales with a targeted eye, reinvesting the money earned from your personal items rather than your savings.
Keep an eye on the drip expenses
Revenue is vanity; net profit is reality. Resellers who quit early often do so because small unrecorded expenses quietly ate their margin:
Shipping scale
A cheap digital kitchen or postal scale. Guessing parcel weights at the post office counter is the fastest way to lose money on shipping.
Measuring tape
Essential for clothing dimensions (chest, inseam) and parcel box dimensions (carriers charge dimensional weight for large boxes).
Packaging supplies
Save clean delivery boxes and bubble wrap from your own online shopping. Only buy poly mailers or packing tape in bulk when you run low.
Platform fees & postage
Marketplaces take roughly 12% to 15%+ off the top. Always check your net payout after postage and fees before celebrating a sale.
Keep your transactions in one place from day one
Do not wait until tax season to track your numbers. Keep your original store receipts, thrift slips, postage costs, and packaging purchases in one organized spot.
When you have five items listed, a notes app or a paper notebook works. Read our guide on what records resellers should actually keep.
When your inventory climbs from ten items to fifty or two hundred, a purpose-built app like ItemLogue does the heavy lifting: scan purchase receipts, calculate true cost after taxes and shipping, track where items are stored, and calculate real net profit the moment each piece sells.
Start small. Build the right habits.
ItemLogue tracks purchase costs, fees, postage, and profit from your very first sale.
