The Multi-Channel Seller’s Playbook: How to Win on TikTok Shop, Amazon & More

Single-Platform Selling is Dead. Here’s How to Win in 2025.

If you’re only selling on Amazon, TikTok Shop, or Shopify, you’re leaving money on the table.

The future of eCommerce isn’t about picking one platform—it’s about leveraging all of them.

Smart sellers are winning on multiple platforms at once, using a multi-channel strategy to:

✅ Increase sales without relying on one marketplace
✅ Reach new customers where they already shop
✅ Protect their business from algorithm changes & account bans

If you want to scale without the stress, this is your step-by-step playbook for becoming a multi-channel seller in 2025.

Why Every Seller Needs a Multi-Channel Strategy

The biggest mistake eCommerce brands make?

❌ They put all their eggs in one basket.

If you’re only selling on Amazon, Shopify, or TikTok Shop, you’re at the mercy of one platform’s rules, fees, and algorithm changes.

Here’s why single-platform selling is a bad idea:

🔥 Amazon keeps raising FBA fees—cutting into your margins
🔥 TikTok Shop algorithm changes can tank your sales overnight
🔥 Shopify isn’t a marketplace—you need to drive all your own traffic

Multi-channel sellers win because they spread the risk.

💬 Ben Thorpe, 3PL Pro:
"Sam’s knowledge and attention to detail are miles ahead of traditional accountants. I took a leap of faith, and within two weeks, I knew I made the right decision."

The 4-Step Multi-Channel Playbook for eCommerce Sellers

Want to start selling on multiple platforms without losing your mind?

Here’s how to build a multi-channel strategy that actually works.

1️⃣ Choose the Right Platform Mix

Not every platform is right for every brand. Here’s how to decide where to sell:

✔ Amazon – Best for credibility & high-intent buyers
✔ TikTok Shop – Best for viral, impulse-driven purchases
✔ Shopify – Best for brand control & repeat customers

💡 Pro Tip: Use Amazon for trust, TikTok Shop for discovery, and Shopify for long-term brand growth.

💬 Dan Riley, Stoic Store:
"Switching to Social Commerce Accountants was the best business decision I made. Communication, efficiency, and expertise are top-notch. My only regret? Not switching sooner."

2️⃣ Price Smartly Across Platforms

Pricing the same on every platform? Big mistake.

• Amazon: Keep prices competitive to win the Buy Box.
• Shopify: Use bundles, subscriptions & exclusives to boost AOV.
• TikTok Shop: Offer flash sales & influencer deals to trigger impulse buys.

Strategy in action: Sell a product for £20 on Amazon but offer a "Buy 2, Get 1 Free" bundle on Shopify to increase order value.

💬 Kevin Lew, Moicha Matcha:
"The best accountants. Meticulous, knowledgeable, and responsive. Highly recommend this team!"

3️⃣ Sync Inventory & Fulfilment Across All Platforms

One of the biggest multi-channel mistakes? Inventory chaos.

How to fix it:

✔ Amazon Sellers → Use Amazon Multi-Channel Fulfilment (MCF) to ship Shopify & TikTok orders.
✔ Shopify & TikTok Sellers → Use a 3PL that integrates with both platforms.
✔ Scaling fast? Consider TikTok Shop Fulfilled by TikTok (FBT) for faster delivery.

Pro Tip: If you’re selling the same product on multiple platforms, avoid using the same UPC (barcode) across all listings. Amazon can flag it as duplicate content.

💬 Mendel Brackman, The Whisky Stock:
"Sam’s communication was top-notch. He was friendly, efficient, and knew exactly how to handle everything. I’ll definitely use his services again."

4️⃣ Track Profits Across Multiple Sales Channels

Selling on multiple platforms = more revenue but also more complexity.

Most sellers have NO idea what their real margins are.

Why?

• Amazon fees kill profitability if you don’t track them
• TikTok Shop payouts are delayed (so cash flow is tight)
• Shopify has hidden processing fees that add up fast

What you need to do:

✅ Sync all platforms into Xero for real-time tracking
✅ Use Link My Books & Synder to automate sales reconciliation
✅ Hire an accountant who actually understands multi-channel eCommerce

💬 Rory Preston, Eudemo:
"Having a one-stop shop like Social Commerce Accountants makes things significantly easier. Highly recommend for anyone scaling their business!"
