If you're launching or scaling an Amazon or Shopify business, one of the first major decisions you'll face is how to source products. Two of the most popular methods—wholesale and online arbitrage (OA)—both offer paths to profitability, but their operational models, risks, and scaling potential are drastically different.
So which one is better?
The short answer: Wholesale is more scalable and sustainable, but online arbitrage is cheaper and faster to start. According to a 2024 Jungle Scout report, 59% of Amazon sellers prefer private label or wholesale due to repeatable inventory, while 21% rely on online arbitrage for quick, lower-risk entry. Your choice depends on your experience level, capital, time availability, and risk tolerance.
1. Product Sourcing: How You Get Inventory
The way you source inventory sets the foundation for your entire business. Wholesale means you’re purchasing products directly from official distributors, manufacturers, or brand owners.
These suppliers typically expect a formal relationship: you register for an account, submit resale certificates, and place bulk orders. Once approved, you can often order the same product multiple times, building a stable supply chain.
Online arbitrage flips that model. Instead of working with suppliers, you're buying discounted or clearance products from retail websites like Target, Walmart, or Walgreens. You look for price differences between these sources and Amazon listings, then profit by reselling the product. However, you often deal with limited-time deals, and you’re always in search of the next opportunity.
Method | Product Source | Example |
Wholesale | Manufacturer or official distributor | Buy 500 units of Logitech mice from an authorized tech distributor |
Online Arbitrage | Retailers, online marketplaces | Buy 3 discounted Lego sets from Walmart.com |
In 2024, SellerApp found that 71% of wholesale sellers rely on only 2–3 trusted suppliers, while OA sellers typically monitor over 8 different retail websites to maintain consistent profits.
2. Order Volume and Pricing
Wholesale is built around bulk buying. Distributors often have minimum order quantities (MOQs) that require you to buy 50, 100, or even 500 units at a time. In return, you get favorable pricing that’s much lower than retail—sometimes even close to manufacturing cost, depending on the size of the order and your negotiation power.
Online arbitrage doesn’t involve bulk orders. You may buy as few as one unit, or stock up on five to ten if you find a great deal. Because you’re buying from retail stores—just like any regular shopper—the per-unit price is higher, and the profit relies on resale price spikes, stockouts, or holiday surges.
Method | Typical Order Size | Price Per Unit |
Wholesale | 100–1,000+ units | Low (bulk pricing) |
Online Arbitrage | 1–20 units | Higher (retail pricing) |
While OA gives you flexibility, wholesale helps you lock in prices and manage inventory predictably, which becomes more important as your sales volume grows and you want to reduce volatility.
3. Profit Margin and ROI
The margins you make on each sale can be very different depending on your sourcing method. Wholesale sellers typically earn smaller but consistent margins, often between 10% and 20%. These margins might not look impressive on paper, but when applied to bulk orders and scalable systems, they provide reliable monthly profits.
Online arbitrage can offer much higher short-term ROI, often exceeding 40% or even 70%, especially when flipping clearance items or holiday deals. The catch? These margins are rarely consistent. As more sellers jump on the same deals, prices drop quickly, and Amazon fees can eat into your margins fast.
Method | Typical ROI | Stability |
Wholesale | 10%–20% | Stable over time |
Online Arbitrage | 20%–50%+ | Highly volatile |
A 2023 RepricerExpress report showed that OA sellers experience price competition on over 60% of new listings within 30 days, leading to sharp margin drops unless inventory is flipped quickly.
4. Time Investment
Time is a limited resource, and how you spend it affects your ability to grow. Wholesale demands more time upfront—you’ll need to vet suppliers, apply for accounts, provide resale documentation, and often engage in negotiation. However, once you establish those relationships, you can place repeat orders and manage restocks with minimal effort.
Online arbitrage, by contrast, requires constant daily involvement. You need to manually scout websites for deals, compare prices with Amazon, check for restrictions, and act fast before stock runs out or prices change. It's ideal if you enjoy the thrill of finding opportunities, but it’s also a job that doesn’t scale easily without hiring a team or using software tools.
Time Comparison |
Wholesale: Setup-heavy, maintenance-light |
OA: Ongoing effort, daily scanning |
Successful wholesale sellers often spend more time analyzing numbers and scaling operations, while OA sellers spend more time just keeping inventory flowing week to week.
5. Brand Approval and Amazon Ungating
Amazon has become increasingly strict with what sellers can list. Certain brands and categories are "gated," meaning you need specific approval and documentation to sell those items. Amazon accepts wholesale invoices for ungating, and they help verify authenticity.
OA sellers often face roadblocks here. Retail receipts are not accepted by Amazon as valid proof of authenticity. Even if the item is genuine, using a retail invoice to defend your account against an IP complaint may not hold up. This significantly limits what you can sell using arbitrage methods.
Brand Compliance | Wholesale | OA |
Amazon Brand Approval | Easier | Often denied |
IP Claim Risk | Low | High |
Proof of Authenticity | Accepted | Frequently rejected |
If you plan to sell brand-name items or enter restricted categories, wholesale is the only sustainable method that protects your seller account from suspension.
6. Scalability
As your sales grow, your business model must grow with it. Wholesale is more scalable because it’s repeatable. Once you identify a winning product, you can place regular orders, outsource prep, and automate inventory tracking. That creates a system where you’re not constantly reinventing your sourcing strategy.
Online arbitrage is difficult to scale in the same way. You’re always searching for new products and deals because stock is limited and prices are volatile. Even with tools like Tactical Arbitrage, you can’t automate sourcing entirely, and many OA sellers find that their profits plateau unless they build teams or hire VAs.
Scalability | Wholesale | Online Arbitrage |
Restocking Ease | High (reorder) | Low (hunt again) |
Automation Tools | Strong integration | Moderate support |
Many six- and seven-figure sellers use wholesale because it allows them to scale their revenue without scaling their workload proportionally.
7. Risk Profile
When it comes to account safety, wholesale carries significantly less risk. Because you’re working with authorized distributors and have valid invoices, the likelihood of receiving an intellectual property (IP) complaint or authenticity claim is very low.
Online arbitrage, while not inherently illegal, is riskier on platforms like Amazon, where authenticity is tightly monitored. Sellers who rely solely on OA often find themselves suspended or dealing with listing removals due to brand complaints, even when the products are real.
Risk Factor | Wholesale | OA |
IP Complaints | Rare | Common |
Proof of Source Accepted | Yes | Often rejected |
Account Suspension Risk | Low | Higher |
Many sellers using OA have had entire accounts deactivated simply because a brand flagged their listing—even when the product came directly from a legitimate store like Walmart or Target.
8. Start-Up Capital
The financial barrier to entry is one of the most important considerations for new sellers. Online arbitrage has the lowest cost to start. You can begin with $300 to $1,000, depending on how many deals you can find. Many sellers start OA during seasonal clearance periods to maximize early profits.
Wholesale, on the other hand, requires more financial commitment. Suppliers often set minimum order amounts or request initial orders worth several thousand dollars. Additionally, you may need to spend money on business registration, sales tax permits, and shipping logistics from the start.
Method | Startup Capital Needed |
Wholesale | $2,000–$10,000+ |
Online Arbitrage | $300–$1,000 |
If capital is your main limitation, start with OA. But reinvest your profits toward transitioning into wholesale, where growth becomes much more predictable.
9. Automation and Delegation Potential
Long-term business success depends on how much of your workload you can delegate. Wholesale allows for extensive automation—you can use software for restocking alerts, inventory management, and supplier communication, according to Amazon. You can also outsource prep work to 3rd-party prep centers and hire virtual assistants for order management.
Online arbitrage does offer tools, but most of the sourcing process still needs human decision-making. Tools like Keepa and Tactical Arbitrage help with scanning, but filtering bad leads and checking restrictions requires active involvement.
Efficiency | Wholesale | OA |
Delegation Ready | Yes (VAs, prep centers) | Partial (manual review) |
Software Support | Strong | Moderate |
If you're building a business you want to run hands-off in the future, wholesale gives you more room to automate and scale than OA ever will.
10. Long-Term Viability
Your sourcing model impacts whether you’re building a job or a sellable business. Wholesale sellers often build repeatable systems, create branded Amazon stores, and maintain consistent relationships with suppliers. This gives them the ability to sell their business as an asset down the road.
OA sellers, while profitable in the short term, often operate like freelancers. The lack of long-term inventory contracts and reliance on fluctuating retail deals means the business has limited resale value.
Business Lifespan | Wholesale | Online Arbitrage |
Brand Building | Possible | Not practical |
Sellable Business | Yes | Rarely |
OA is great for generating fast profits. But if you're looking to build a sustainable, exit-ready business, wholesale gives you a much stronger foundation.
