How to start an online resale business: 7 strategies

I've helped hundreds of folks learn how to start an online resale business by launching on platforms like Poshmark, eBay, and Depop. Here are my top 7 strategies that I always advise new sellers to use.

Strategy 1: Define a clear niche and target audience

Successful resellers avoid selling everything to everyone. Become a specialist by focusing on one category, understanding your target buyers, and tailoring each listing to what your audience wants most. Follow these steps to find your niche and audience:

Step 1: Choose your niche wisely

Pick something you know well or are passionate about, such as vintage denim, 8-bit Nintendo games, or furniture. Specializing helps you spot quality faster and build expertise that buyers trust.

Step 2: Identify your target audience

Figure out who is most likely to buy what you sell. They might be Gen Z trendsetters searching for vintage pieces or budget-conscious parents seeking everyday essentials. Knowing your audience shapes how you photograph, price, and describe each item.

Step 3: Learn what your buyers value

Research what matters most to your target buyer. Some shoppers prioritize aesthetics and unique pieces, while others care about condition, brand names, or low prices. Use these insights to highlight the key details in your titles and listings.

Step 4: Build listings for your target buyers

Write descriptions, choose keywords, and style photos based on what your buyers search for and respond to. Do they love Y2K fashion? Emphasize details from the turn of the 21st century. Are they just shopping for basics on a platform like Mercari? Focus on accuracy, condition, and fast shipping.

Strategy 2: Design a branded buying experience

A strong brand gives your shop a memorable feel, which encourages buyers to trust you and return. Follow these tips to build a brand that brings in buyers:

Tip 1: Choose a consistent visual style for your photos

Determine how you want your photos to appear across your entire shop, so buyers instantly recognize your brand. Pick a mood, color tone, or photography approach that expresses the style you sell. 

Use a photo-editing tool like Nifty’s to align each product picture with your brand. Nifty’s built-in photo editor provides these features: 

• Zoom
• Rotate
• Crop
• Filters
• Brightness adjustment
• Contrast adjustment
• Saturation adjustment
• Add text annotations
• Add shapes to highlight important details

Tip 2: Set rules for lighting and composition

Choose one lighting setup and stick to it so every photo looks clean and consistent. Decide on your go-to angles and framing. Once you determine your lighting and composition for every picture, photographing items becomes simple, routine, and formulaic. 

Tip 3: Use a unified backdrop and formatting pattern

Pick one backdrop that complements your items and use it for every product photo. Keep spacing, cropping, and text formatting consistent, so shoppers know what to expect as they browse. You can remove your backdrop entirely using a background remover like the one provided by Nifty’s integration with Photoroom. 

Tip 4: Organize your storefront to guide browsing

Group similar items together so buyers can move through your shop naturally and find what they want quickly. Use clear categories, titles, or descriptions to help visitors spot themes or styles.

Tip 5: Feature your strongest items with a fresh layout

Highlight your best pieces in high-visibility spots where buyers will see them first. Update these placements regularly so your storefront always looks active and well curated. Featuring standout items can also make a strong first impression when new shoppers visit.

Strategy 3: Create listings built for quick decisions

You’re battling buyers’ attention spans: They scroll fast, compare dozens of items, then navigate over to their Instagram feed. Your listings need to answer their questions immediately and show exactly what they're getting to keep them engaged. 

Follow my listing tips:

Listing tip 1: Make information easy to digest

Your listings’ titles and descriptions should provide the most compelling details, whether that’s the brand, era, condition, or style. Buyers decide within seconds if they’ll keep reading, so front-load information that grabs attention and signals value right away.

Appeal to unique audiences on different platforms, too. If you’re selling branded gear on Poshmark, you’ll want to use language that resonates with this fashion-conscious crowd. But for your Mercari or eBay listings, use more direct language that sums up an item’s measurements and condition details. 

Pro tip: Use an automation tool like Nifty that offers AI listing and description generation. This tool provides SEO optimized keywords that buyers are searching for. Always give them a once-over before publishing. 

Listing tip 2: Make your photos do the heavy lifting

Those captivating, well-lit pictures that you learned in the second strategy will help keep your shoppers’ attention. Here’s how to configure each photo to shine a positive light on your products:

• Show essential details upfront: Present key information immediately so shoppers never guess. Include close-ups of worn areas and standout features to help buyers understand exactly what they are getting.
• Use scale when needed: Display a reference object to help shoppers visualize dimensions accurately when size may be unclear.
• Write clear condition notes: Give buyers precise measurements, condition details, and expected item specifics. Use consistent terminology across listings to make comparisons simple.
• Reinforce the main selling point: Keep phrasing tight and predictable. End with your strongest selling angle, like brand, quality, fit, or rarity.

Strategy 4: Build trust through communication

Building trust through communication helps you earn repeat buyers and reflects well on your reputation as a professional seller. Always answer questions directly with a friendly tone. After purchases, update buyers immediately with shipping details so they feel confident after checkout. 

Thank them with a personalized note to show your appreciation, and nudge them to leave a review. If they need support, provide clear instructions rather than lengthy explanations. 

Strategy 5: Build systems that keep you organized

Build simple systems that reduce decision-making and keep every task easy to repeat as your workflow grows by following these system-building tips:

System tip 1: Plan and structure your weekly workflow

Plan dedicated days for photographing, listing, and packing so you can give each task your full attention. Write down a task list for every day of the week and estimate the time needed for each individual task. This way, you’ll always complete crucial work as your business scales.

System tip 2: Track sales progress consistently

Monitor your weekly sales goals to determine what’s working and where you need to make adjustments. Use simple metrics that show trends instead of being overwhelmed by data. 

By consistently tracking results, you can make quick improvements without slowing your workflow. Always remember to update your weekly workflow plan after making improvements.

System tip 3: Review and update old listings

Build a rotation for refreshing older listings so nothing sits stale. Update photos, adjust pricing, or rewrite titles when needed. A routine review keeps your catalog active and increases visibility on search-driven platforms.

System tip 4: Organize and label your inventory

Create a simple shelving or bin system with clear labels, making it easy to retrieve items. Use straightforward identifiers that match what appears in your listings. Good organization saves time during packing and prevents mix-ups with similar products.

System tip 5: Centralize product details

Store all item specifics, measurements, and reusable listing templates in one place. Keeping everything in one place reduces repetitive work and helps you list new products faster. Centralized information also makes it easier to train help if you scale.

System tip 6: Manage your operation from one dashboard

Manually tracking your profits and time in inventory with spreadsheets is a recipe for chaos. Instead, use a tool like Nifty that helps you see how long items have been sitting, track slow movers, and provides an in-depth analytics dashboard. 

Nifty also saves you from bouncing between platforms, allowing you to relist on eBay, Poshmark, Mercari, Etsy, and Depop. It helps you track your sales with its detailed analytics suite. The tool also recommends a number of daily relists based on your closet size while following each platform’s relist rules. 

Strategy 6: Shape your customer experience

Each sale doesn't end when a buyer clicks purchase. The way you package your items and how you communicate during shipping determines whether someone becomes a repeat customer. 

Make receiving your items memorable and encourage repeat purchases

Use clean, consistent packaging that reflects your brand, whether you choose recycled boxes, branded tissue paper, or branded tape. Include a short handwritten thank-you note or a printed card that gives each purchase a personalized feel.

Neatly folded items, secure packaging, and branded stickers create a polished unboxing experience. Pack all items in the same way to maintain quality without spending too much time on each order. 

Research shows that thoughtful, branded packaging significantly improves perceived quality and preferences. When buyers feel impressed by the packaging and overall experience, they are more likely to leave better reviews. 

Further encourage buyers to share their experiences on sales platforms and social media by offering limited-time discounts or exclusive access to your live-stream events. 

Strategy 7: Grow with intentional expansion

Once you've built a buyer base and a clear brand identity, it’s time to start scaling so you can really bring home the bacon. Follow these tips to expand your online resale business:

• Add inventory that supports your brand: Choose new products that align with your existing niche and aesthetic. If you sell vintage denim, consider adding vintage tees or accessories rather than jumping into unrelated categories that confuse your shop's identity.
• Introduce new categories gradually: Don’t overhaul your entire shop overnight. Instead, add one or two new categories at a time, allowing you to test what buyers respond to without risking major losses. This slow expansion helps you see what works before investing more time or inventory.
• Test buyer interest: List a few sample items in a new category and watch how buyers respond through engagement, questions, and sales. Use that data to decide whether the category fits your audience or if you should stay focused on your core inventory.
• Track categories: Review which items get the most views, favorites, and sales. Double down on high-performing categories by sourcing more of what buyers already want, rather than spreading effort across products that don't move.
• Share previews and build buyer community: Post sneak peeks of new arrivals or upcoming drops on your socials to generate excitement. Engage with followers who comment or ask questions and build anticipation that keeps buyers coming back to check your latest listings regularly.

Starting an online resale business is a marathon, not a sprint. By dedicating a few hours each day over the long term and never letting up, you’ll gradually refine your niche and discover the products that appeal most to your target audience.
