First 100 Sales Checklist: What to Do Before, During, and After Launch

2026-04-08

You want to start selling online. You've seen the success stories. But between the gurus, the courses, and the conflicting advice, it's hard to know what actually matters.

Here's a grounded, data-backed checklist. No hype. Just what works, what it costs, and how long it takes — based on real seller data.

The Reality Check

Before you start, know the terrain:

• 80-90% of e-commerce businesses fail overall. 40% fail within the first two years (Failory)
• Average time to first sale: 3 months on Amazon, 1-3 weeks on Etsy, 2-4 weeks on Shopify (TrueProfit, TechPenny, ShopThemeDetector)
• 64% of Amazon sellers become profitable within 12 months (TrueProfit)
• Average Amazon FBA startup cost: $3,836 (Jungle Scout)

This isn't meant to scare you. It's meant to calibrate your expectations. The sellers who succeed aren't lucky — they're methodical.

Phase 1: Before Launch (Weeks 1-4)

Platform Startup Costs

Sources: Etsy Fees, Shopify Pricing, Jungle Scout

Checklist: Research & Preparation

• Pick ONE platform to start — Don't split your attention across 3 platforms. Amazon if you want built-in traffic. Etsy if you make handmade goods. Shopify if you want brand control.
• Validate demand — Use free tools: Amazon Best Sellers rank, Etsy search suggestions, Google Trends. If nobody is searching for your product, nobody will find it.
• Calculate unit economics — Product cost + shipping + platform fees + advertising = total cost per unit. Your selling price must exceed this with enough margin to survive.
• Order samples before bulk — Test quality before committing $500-5,000 to inventory.
• Set up business basics — Business bank account, basic bookkeeping (Wave is free), understand tax obligations.

Phase 2: Product Photography (Week 3-4)

This is where most new sellers rush and regret later. 90% of online buyers consider product photos essential to their purchase decision (Skywall Photography).

Checklist: Photography

• Set up a simple shooting area — Window + white poster board. Total cost: $2-3. See our lighting guide.
• Shoot 5 angles per product — Front, back, side, detail close-up, scale reference.
• Clean every product before shooting — Dust and fingerprints show up at zoom.
• Process backgrounds — BgSwap generates 15 marketplace-ready backgrounds per product. $4.99 for 10 products. Upload one photo free to test.
• Create 1 infographic image — Feature callouts and dimensions using Canva (free).
• Check images on your phone — Over 70% of your customers will see them on mobile.

Photography Budget

For your first 10 products, phone + window is enough. Invest in professional photos after you've validated that the product sells.

Phase 3: Listing Creation (Week 4-5)

Checklist: Your Listing

• Title — Include your main keyword naturally. Amazon: 150-200 characters. Etsy: use all 140 characters. Shopify: short and clear.
• Description/Bullet Points — Lead with benefits, not features. Address the top 3 buyer objections.
• Images — 5-7 images minimum. Use all available slots.
• Price — Research competitor pricing. Don't be the cheapest — it signals low quality. Don't be the most expensive without justification.
• Keywords (Amazon/Etsy) — Use backend search terms. Tools: Helium 10 (Amazon), eRank (Etsy) — both have free tiers.
• Shipping — Free shipping converts better. Build shipping cost into your price if needed.

Phase 4: Launch (Week 5-6)

Checklist: Go Live

• Place a test order yourself — Check the customer experience end-to-end. Is the product page clear? Does checkout work? Does the confirmation email make sense?
• Get your first 5 reviews — Amazon: use the "Request a Review" button in Seller Central. Etsy: send a thank-you message after delivery. Shopify: set up automated review request emails (Judge.me is free).
• Run a small ad campaign — Amazon Sponsored Products ($10/day) or Facebook/Instagram ads ($5-10/day). The goal isn't profit — it's data. Learn which keywords and audiences work.
• Tell everyone you know — Family, friends, social media. Your first sales often come from your network. That's normal and fine.

Phase 5: First 30 Days (Optimize)

Checklist: Learning from Data

• Check your conversion rate — Amazon: Business Reports → Detail Page Sales and Traffic. Shopify: Analytics → Online store conversion rate. Etsy: Stats → Conversion rate.
• Average conversion benchmarks — Amazon: 10-13%. Shopify: 1.4-1.8%. Etsy: 2-3% (Envive, Blend Commerce).
• If below average: Fix images first, then description, then pricing.
• Read every review and customer message — These are free product research. What do customers love? What do they complain about?
• Adjust pricing if needed — If you're not getting clicks, your price might be too high for your image/review combination. If you're getting clicks but no sales, your listing needs work.

Phase 6: Path to 100 Sales

What Successful Sellers Do Differently

Based on Jungle Scout's annual seller survey (2025 report):

• 61% sell on at least one other platform
• 41% use social media marketing
• 80% have adopted AI tools for some part of their operations
• 49% plan to work with influencers

Timeline Expectations

The Compound Effect

Your first 10 sales are the hardest. Each sale generates data (conversion rate, customer feedback) that helps you improve. Each review builds trust that makes the next sale easier.

• Sales 1-10: Hard. Mostly from ads and personal network.
• Sales 11-50: Easier. Reviews and organic visibility start kicking in.
• Sales 51-100: Momentum. You have enough data to optimize confidently.

Common First-Timer Mistakes

Your Total Startup Cost (Realistic)

You don't need $3,836 to start (that's the average, inflated by sellers who over-invest in inventory before validating). You can test a product idea for under $400.
