SAVE FOR LATER
Starting a reselling business was never on my radar until I realized how much potential income was sitting in thrift stores, garage sales, and even my own closet. If you’re looking to build some extra income while working from home, reselling might be perfect for you. Perhaps you’ve seen success stories of people making thousands each month buying low and selling high online, or maybe you’re just trying to find a flexible side hustle that can work around your family’s schedule.
In this article, I’m sharing exactly how to start a reselling business that can grow from a small side income into something more substantial. These practical steps will help you navigate the early stages and avoid common pitfalls that new resellers face. With some dedication and smart planning, you can build a profitable reselling operation that fits your lifestyle.
Essential Steps to Launch Your Reselling Business
1. Choose Your Reselling Niche
Starting with a specific niche helps you become an expert faster in the reselling world. While it might seem smart to sell anything you can find, focusing on a particular category allows you to develop specialized knowledge and recognize valuable items instantly. Your expertise will grow much quicker when you’re researching a focused area rather than trying to learn about everything at once.
Consider starting with items you already know about: clothing brands you wear, books in genres you enjoy, or vintage items you already collect. Your existing knowledge gives you an advantage in spotting underpriced items and understanding what buyers in that niche are willing to pay. This foundation of knowledge will serve as your competitive edge when sourcing inventory.
As you gain experience and confidence in your primary niche, you can gradually expand into related categories. Many successful resellers begin with women’s clothing and then branch into men’s apparel or children’s items as they build their business. This strategic growth allows you to leverage your existing knowledge while expanding your potential inventory sources.
2. Research Profitable Platforms
Each online marketplace has its own unique atmosphere and customer base. Poshmark works well for trendy clothing and accessories, while eBay has a broader reach for almost anything from electronics to collectibles. Mercari is gaining popularity for its straightforward fee structure, and Facebook Marketplace excels for local sales of furniture and larger items.
Take time to browse each platform, noting what sells well and for how much in your chosen niche. Look at completed listings (not just active ones) to see actual selling prices rather than aspirational pricing by other sellers. This research reveals where your specific inventory will likely earn the most money and which platform’s fee structure will leave you with the highest profit.
Many successful resellers use multiple platforms strategically, listing higher-end clothing on Poshmark while selling unique collectibles on eBay for maximum visibility. Your research might show that certain brands or items consistently sell for more on one platform than another. This knowledge allows you to list strategically for maximum profit rather than placing all items on a single marketplace.
3. Set Up a Proper Business Structure
While you can start reselling as a casual hobby, treating it like a legitimate business from day one will save you significant headaches later. At minimum, create separate bank accounts and tracking systems for your reselling activities to keep personal and business finances clearly separated. This separation makes tax time much simpler and gives you clearer insight into your actual profits.
Consider registering as a sole proprietor using your social security number, or forming an LLC for additional protection as your business grows. Each state has different requirements and fees for business registration, so check your local regulations before making this decision. Many resellers begin as sole proprietors and transition to an LLC once their business reaches a certain income threshold.
Track every purchase, sale, and expense from the beginning using either spreadsheets or accounting software designed for small businesses. This organization will be invaluable during tax season and when analyzing which types of items give you the best return on investment. Your financial tracking system doesn’t need to be complex, but it should be consistent and thorough enough to give you accurate insights into your business performance.
4. Acquire Inventory Strategically
The fundamental principle of reselling: you make your money when you buy, not when you sell. This means finding items at prices low enough to ensure profit after accounting for all fees, shipping costs, and your time. Your sourcing strategy will directly determine your potential profit margins.
Start with sourcing from:
- Thrift stores (especially on sale days when prices are reduced)
- Garage and estate sales (arrive early for best selection)
- Clearance racks at retail stores (end-of-season sales offer particularly good margins)
- Your own unused items (a zero-cost way to learn the selling process)
Don’t purchase something simply because it’s inexpensive—research its resale value first using sold listings on your target platforms. Many new resellers make the costly mistake of buying items they personally find appealing rather than what market research shows will sell profitably. Your inventory should be guided by data and profit potential, not personal preference or assumption.
5. Apply for a Reseller Certificate
A reseller certificate (sometimes called a resale certificate or tax exemption certificate) allows you to purchase inventory without paying sales tax, since your customers will pay sales tax when they buy from you. This document essentially verifies to suppliers that you’re buying products for resale purposes, not personal use. Without this certificate, you’re essentially paying tax twice on the same items—once when you buy, and again (through your customer) when you sell.
Requirements vary by state, but this document can save you significant money on inventory purchases, especially from wholesale sources or when buying in bulk. In some states, you’ll need to register for a sales tax permit first, while others allow you to apply for a reseller certificate directly. The process typically involves filling out an application with your business information and submitting it to your state’s tax authority.
Keep meticulous records of purchases made with your reseller certificate, as you’ll need to demonstrate these items were indeed resold and not used personally. Most states require you to maintain these records for several years in case of an audit. For each tax-exempt purchase, store a copy of the invoice along with information about when and where you eventually sold the item.
6. Create a Photography Setup
Clear, detailed photos dramatically increase your sales potential by helping buyers feel confident about what they’re purchasing. You don’t need professional equipment—a smartphone with good lighting can work perfectly for beginners. Your goal is consistency and clarity rather than artistic perfection.
Invest in:
- A plain background (white poster board or fabric works well)
- Natural lighting near a window or inexpensive ring lights
- A mannequin or dress form for clothing items
- Small props that show scale for jewelry or collectibles
Take multiple angles of each item, capturing any flaws honestly and thoroughly. Misrepresenting an item’s condition leads to returns, negative feedback, and potential account problems on selling platforms. Your photos should tell the complete story of the item’s condition, even before buyers read your description.
Lighting tip: Natural light from a north-facing window provides consistent, flattering illumination without harsh shadows. If natural light isn’t available, consider affordable LED lighting that mimics daylight. Many successful resellers create a dedicated photo area in their home where lighting and backgrounds remain consistent across all listings.
7. Master Listing Descriptions
Your item descriptions need to answer any possible questions a buyer might have before they need to ask them. Include detailed information about dimensions, materials, condition, brand, style, and any special features that make the item desirable. This comprehensive approach reduces questions from potential buyers and increases their confidence in making a purchase.
Use keywords strategically in titles and descriptions to help buyers find your items when searching. For Poshmark specifically, include style names and seasonal tags that shoppers might search for when looking for specific items. Research shows that listings with detailed, keyword-rich descriptions typically rank higher in platform search results and sell faster.
Condition notes: Be meticulously honest about any flaws, no matter how small. Describing a tiny pinhole or faint stain upfront builds trust and prevents returns. Many successful resellers even include close-up photos of minor flaws alongside detailed descriptions of their exact location and severity.
8. Develop an Inventory System
As your business grows beyond a few items, you’ll need a reliable way to keep track of your merchandise. Many beginners start with a spreadsheet tracking essential information about each item in their inventory. This system helps you maintain control as your business scales and prevents costly mistakes like selling items you can’t find.
For physical organization, consider a numbered bin system where each item gets assigned to a specific storage location that’s noted in your tracking system. This approach allows you to quickly locate any item when it sells without needing to remember what each piece looks like. The time saved during the fulfillment process will become increasingly valuable as your inventory grows.
Inventory tracking columns: At minimum, your inventory spreadsheet should include item description, SKU or inventory number, purchase price, purchase date, source, date listed, platforms listed on, storage location, and final selling price. This information allows you to analyze which sources, categories, and price points yield the best returns over time.
9. Set Realistic Pricing
Pricing is both art and science in the reselling business. Research completed listings of similar items to understand the current market rate, then consider your specific costs before setting your price. Your pricing strategy should balance competitive positioning with profitability goals.
Consider these factors when pricing:
- Your purchase price (including any taxes paid)
- Platform fees (usually 10-20% of the sale price)
- Shipping costs (even for “free shipping” offers)
- Time invested in sourcing, cleaning, photographing, and listing
Many successful resellers aim for at least tripling their investment on each item (the 3x rule), though margins vary widely by category and brand. Some low-cost items might warrant a 5x markup, while more expensive pieces might sell with just a 2x return. Your pricing strategy should be flexible but guided by consistent profit goals.
10. Create Efficient Shipping Processes
Shipping quickly and safely is essential for positive reviews and repeat customers in the reselling business. Stock up on various size polymailers, boxes, tissue paper, thank you cards, and a reliable postal scale to ensure you’re prepared when sales come in. Creating a dedicated shipping station in your home with all supplies organized and accessible will save significant time.
Take advantage of free shipping supplies from USPS for Priority Mail, and consider purchasing other shipping materials in bulk for significant savings. Many experienced resellers order custom-branded packaging once their business reaches a certain volume, which enhances the unboxing experience for customers and increases the likelihood of repeat business.
Shipping schedule: Establish a routine for packing and shipping—many resellers designate specific days for post office runs to batch this task efficiently. Setting a consistent shipping schedule helps you manage buyer expectations and integrate your reselling business into your broader life responsibilities.
11. Provide Outstanding Customer Service
In a competitive reselling market, excellent customer service helps you stand out and build a loyal customer base. Respond to questions quickly, ship promptly, and resolve issues generously without becoming defensive. Your reputation on selling platforms directly impacts your visibility and sales potential.
When problems arise (and they inevitably will), focus on solutions rather than placing blame or becoming frustrated. A refund or partial refund can transform a potentially negative experience into a positive one that might even result in a repeat customer. Many successful resellers view customer service challenges as opportunities to demonstrate their professionalism.
Response templates: Create pre-written responses for common questions or situations to save time while maintaining a friendly, helpful tone. Templates for sizing questions, bundling requests, and shipping inquiries allow you to respond promptly without composing unique messages each time. Your efficiency in communication contributes significantly to your overall business productivity.
12. Scale Your Business Gradually
As you become more comfortable with reselling and begin seeing consistent profits, look for opportunities to scale thoughtfully rather than rapidly. Reinvest a portion of your profits into higher-quality inventory that offers better margins. This gradual reinvestment approach builds your business sustainably without creating cash flow problems.
Take time to analyze which items and categories bring the highest return on investment, then focus your scaling efforts in those directions. Your business data should guide your growth strategy, revealing which brands, price points, and categories deserve more of your sourcing budget. This analytical approach to scaling prevents costly inventory mistakes that could stall your business growth.
Time management: As your business grows, evaluate which tasks deliver the highest value and which could be streamlined or eventually outsourced. Many successful resellers eventually hire photographers, listers, or shipping assistants to handle time-consuming aspects of the business. Your time is a limited resource, and allocating it strategically becomes increasingly important as your business expands.
