Tips for Success

Develop a methodical approach to finding profitable inventory. For beginners, start with the "bins" section at Goodwill Outlets ($1.49-$1.99/lb) or church rummage sales (fill-a-bag for $5-10) to minimize risk while learning. Advanced resellers should create a sourcing calendar tracking estate sales, seasonal thrift store tag sales (50-75% off colored tags), and retail clearance cycles. Avoid the common mistake of buying items solely because they're cheap—always check comparable sold listings first to verify demand and profitability.

Create a streamlined system to maximize efficiency. Beginners should batch similar tasks—photograph 15-20 items in one session, then create listings the following day. Advanced sellers should develop templates for common brands and styles with pre-filled description frameworks and measurement placement. Invest in a photo backdrop ($15-30), adjustable mannequin ($75-150), and ring light ($30-60) to create consistent, professional images. A critical mistake to avoid is insufficient measurements—always include bust, waist, hip, inseam, rise, and length measurements to reduce questions and returns.

Price your items to maximize both profit and sales velocity. Beginners should start with the "comps plus 20%" rule—research similar sold items and list 20% higher to leave room for offers and discounts. Advanced resellers should implement a dynamic pricing strategy with automated price drops every 14-21 days and strategic relisting of stale inventory after 60 days to trigger algorithm boosts. A major mistake to avoid is emotional pricing—basing prices on what you paid or personal attachment rather than market data. Remember that 70-80% of sales occur through offers rather than full-price purchases.

Each reselling platform has unique algorithms and buyer behaviors requiring tailored approaches. Beginners should focus on mastering one platform completely before expanding—Poshmark for women's contemporary fashion, eBay for vintage and unique pieces, or Mercari for everyday brands. Advanced sellers should leverage cross-posting tools like List Perfectly or Vendoo ($25-50/month) to maintain presence across 4+ platforms while understanding the nuances of each—like Poshmark's emphasis on daily sharing (3x daily for best results) versus eBay's SEO-driven listing titles (80 character keyword-rich titles). A common mistake is treating all platforms identically, missing the opportunity to optimize for each marketplace's specific algorithm and customer base.

Create a cohesive visual and service experience that makes your shop memorable. Beginners should establish consistent photography style, packaging, and communication tone from day one. Advanced resellers should develop a niche specialization (sustainable fashion, size-inclusive professional wear, vintage denim, etc.) and create branded packaging with logos, thank-you cards, and social media information. Consider creating a simple logo ($5-50 on Fiverr) and custom poly mailers ($0.25-0.50 each in bulk). A significant mistake is neglecting the unboxing experience—including a handwritten thank-you note increases positive reviews by approximately 30% and repeat customer rates by 20-25%.

Track performance metrics to guide business decisions. Beginners should maintain a basic spreadsheet recording cost, listing date, sale date, and profit margin for each item. Advanced resellers should analyze sell-through rates by category, brand, and price point, then adjust sourcing accordingly—focusing on items with 60%+ sell-through rates within 30 days. Use inventory aging reports to identify items over 60 days old for aggressive discounting or lot selling. A common mistake is the "sunk cost fallacy"—holding onto slow-moving inventory too long because of your initial investment. Implement a strict 90-day rule: if an item hasn't sold despite multiple promotions, donate it for the tax deduction and reinvest shelf space in faster-moving inventory.

Multiply your productivity by delegating time-consuming tasks. Beginners should identify their "bottleneck" process (often photography or measurements) and consider family help or bartering with other resellers. Advanced sellers should hire specialized assistance—virtual assistants in the Philippines ($5-7/hour) for listing creation, local part-time help ($15-20/hour) for photography and measurements, or consignment relationships with clothing collectors (50/50 profit split). Calculate your effective hourly rate for each task to determine outsourcing priorities—photography might take you 2 minutes per item while listing creation takes 8 minutes, making listing the better outsourcing candidate. A critical mistake is premature scaling—wait until you're consistently selling 50+ items monthly before investing in paid help, and start with just 5-10 hours weekly to refine your delegation process.
