What to Check Before Buying a Shopify Store: The Ultimate Due Diligence Guide
Buying an existing Shopify store can be an incredible shortcut to e-commerce success. Instead of spending months or even years building a brand, testing products, and acquiring your first wave of customers, purchasing an established store hands you a running engine. You get existing traffic, a proven sales history, established supplier relationships, and, best of all, immediate cash flow. However, buying a website is a lot like buying a used car (or a house): what you see on the surface isn’t always what you get.
Many first-time buyers are blinded by impressive revenue screenshots or flashy dashboards, only to realize post-purchase that the store's traffic is unstable, the profit margins are razor-thin, or the customer list is completely disengaged. Whether you are looking at listings on marketplaces like Flippa, Empire Flippers, or Acquire.com, performing thorough due diligence is non-negotiable. At Trend Hijacking, we believe in cutting through the noise, leveraging current market movements, and making smart, calculated digital investments. This comprehensive guide covers everything you need to check before wiring a single dollar for a Shopify store.
Verify Financials (Profit & Loss / P&L)
Revenue is vanity; profit is sanity. It is dangerously easy for a seller to show you a screenshot of a store generating $50,000 a month in gross revenue, while conveniently leaving out the fact that it costs $48,000 a month in ad spend and product costs to generate it.
A. Gross Revenue vs. Net Profit
Always request a verified Profit & Loss (P&L) statement covering at least the last 12 to 24 months. Look beyond the top-line revenue and break down every single expense line item:
Cost of Goods Sold (COGS): What does it cost to manufacture and ship the product?
Merchant Processing Fees: Shopify Payments, PayPal, or Stripe fees.
Software & App Subscriptions: Does the store rely on a dozen expensive monthly Shopify apps for upsells, subscriptions, or reviews? These costs add up fast and eat into margins.
Virtual Assistants or Customer Support: Are there ongoing payroll expenses required to keep the store running?
B. Verify Through Independent Dashboards
Never rely solely on seller-provided CSV files or screenshots (which can easily be altered). Insist on:
Direct Shopify Admin Access (or a live screen share): View the analytics tab live to trace historical revenue, conversion rates, and order counts.
Payment Gateway Verification: Cross-reference the Shopify P&L statements directly against payouts from Shopify Payments, PayPal, or Stripe accounts to ensure the money actually hit the bank.
Looking to Acquire an E-Commerce Business?
Finding the right business takes more than browsing listings. You need an opportunity that fits your budget, aligns with your objectives and has genuine potential to grow.
Trend Hijacking helps entrepreneurs, investors, and strategic buyers source e-commerce businesses, access off-market opportunities, conduct due diligence, negotiate deals, and navigate the acquisition process from start to finish.
Tell us what you're looking to acquire, and let's find the right opportunity for you.
Traffic Sources & Sustainability
Where do the customers come from, and will they keep coming after the current owner leaves? If 90% of a store's traffic comes from a single Facebook ad account that the seller is shutting down, you aren't buying a business—you’re buying an ad strategy that you’ll have to rebuild from scratch.
Traffic Channel Breakdown:
• Organic Search (SEO) — High lifetime value, sustainable growth, and lower long-term acquisition costs.
• Paid Media (Meta, Google, TikTok) — Capital-intensive performance channels requiring continuous optimization and testing.
• Social & Influencer Channels — Highly reliant on consistent content velocity and active creator partnerships.
A. Traffic Diversion and Quality
Analyze Google Analytics (or Shopify Analytics) to understand the traffic breakdown:
Organic Search (SEO): Look for consistent, stable traffic coming from Google search terms. This is high-value, sustainable traffic that doesn’t require ongoing ad spend. Check Ahrefs or SEMrush to see if their rankings are stable or declining.
Paid Advertising: If the store relies heavily on Facebook, Instagram, TikTok, or Google Ads, evaluate the Return on Ad Spend (ROAS). Are ad costs rising year-over-year? Can you maintain profitability if ad platforms change their algorithms?
Direct & Social: Is there a loyal community on Instagram or TikTok? Make sure those social media accounts and email lists are part of the sale agreement.
Product Catalog & Supplier Relationships
You need to know what you are selling and who is making it. A great store with a broken supply chain is a ticking time bomb.
A. Product Viability & Trends
Lifecycle Stage: Is the store riding a short-term fad that is about to crash, or is it an evergreen niche? (At Trend Hijacking, we track how quickly consumer interests shift to make sure you aren't buying a product at the very end of its trend cycle).
Return & Refund Rates: High return rates can quietly sink a profitable store. Check the Shopify admin for product return requests and customer complaints. If a product has a 20% return rate due to poor quality, your margins will evaporate.
B. Supplier Due Diligence
Direct Supplier Access: Can you easily communicate with the manufacturers, or are you dependent on a convoluted dropshipping chain with 30-day shipping times?
Contractual Continuity: If the store relies on private-label manufacturing, request copies of supplier agreements, minimum order quantities (MOQs), and lead times. Ensure these contracts can be legally transferred to your name.
Customer Database & Email Marketing Health
An engaged customer list is often the most valuable asset a Shopify store possesses. However, a bloated, unengaged list can actively harm your business.
A. Email & SMS Marketing Metrics
Ask for access to the store's email service provider (Klaviyo, Mailchimp, Omnisend, etc.) and check:
List Size vs. Engagement: A list of 100,000 subscribers with a 2% open rate is worth far less than a clean list of 10,000 subscribers with a 35% open rate.
Spam Complaints and Bounces: Check the list hygiene. High bounce rates or spam complaints will land your domain on email blacklists immediately after takeover.
Automated Flows: A healthy store should have automated email flows set up (Welcome Series, Abandoned Cart, Browse Abandonment, Post-Purchase). Evaluate how well these flows are configured and what percentage of revenue they generate.
A Shopify store is a digital storefront built on code, apps, and legal agreements. Overlooking technical or legal debt can result in costly headaches right after purchase.
A. Store Audit
App Dependency & Bloat: Check how many apps are installed. Do they slow down site loading speeds? Slow sites kill mobile conversion rates.
Theme and Custom Code: Is the store using a standard, easily updateable Shopify theme, or is it heavily custom-coded by a developer who is no longer around? Custom code without documentation can break during Shopify updates.
Domain History: Use tools like the Wayback Machine and Google Transparency Report to check if the domain has a clean history, has ever been penalized by Google, or has been used for spammy redirects.
B. Legal & Intellectual Property
Trademarks and Copyrights: Does the brand own its logo, brand name, and product designs? Ensure there are no pending trademark disputes or copyright infringement claims.
Customer Data Compliance: Ensure the store complies with privacy regulations like GDPR (Europe) and CCPA (California).

Operational Handover & Transition Support
Even the best-documented store requires a transition period. Systems break, suppliers need introductions, and customer service queues need clearing.
Transition Period Length: Negotiate a minimum of 30 days (ideally 60 days) of transition support from the seller.
Scope of Support: Ensure the contract clearly outlines what the seller will help with: answering supplier intros, explaining ad account structures, training you on customer support workflows, and transferring all digital assets (social handles, domain registrars, ad managers, Shopify account ownership).
Earn-Out Structures: For larger acquisitions, consider structuring part of the purchase price as an earn-out (e.g., paying a portion upfront and the remainder over 3–6 months based on performance) to ensure the seller remains invested in a smooth handover.
