Let’s talk about the single biggest growth lever that OnBuy, eBay, TikTok Shop, and Etsy are leaving untouched.
While they’re all fighting over one-time transactions and viral moments, they’re ignoring what could double their revenue overnight: B2C Subscribe & Save.
This isn’t just a “nice feature.” It’s a growth rocket ship that Amazon & Mega Web Shops have been riding for years. And every day these platforms ignore it, they’re leaving billions on the table for both themselves and their sellers.
The Subscription Economy is Exploding – And They’re Watching From the Sidelines
Let’s look at the numbers that should be keeping these platform CEOs awake at night:
- The UK subscription box market has grown by 350% since 2020 and is set to hit £4.1 billion by 2025 (Royal Mail, 2024)
- UK subscription customers spend 4x more annually than one-time buyers (Barclays Consumer Spend Data, 2024)
- 83% of UK adults now have at least one subscription service (Ofcom “The Subscription Nation” report, 2024)
- UK subscription businesses are growing 6x faster than traditional retail (Office for National Statistics, 2024)
- The UK has the highest subscription adoption rate in Europe, with London leading at 89% household penetration (YouGov UK, 2024)
Yet OnBuy, eBay, TikTok Shop, and Etsy are treating every sale like it’s the first and last. It’s like running a marathon but refusing to tie your shoes.
The Platform-by-Platform Growth Disaster
OnBuy: The “Future-Proof” Platform Stuck in the Past
OnBuy talks about European domination and seller-friendly policies. But where’s the innovation? They have the perfect catalog for subscriptions:
- Home & garden essentials
- Pet supplies & food
- Health & beauty products
- Baby & child essentials
The Growth Opportunity: They could become the “Subscription HQ for European households.” Instead, they’re just another marketplace.
OnBuy’s One-Time Model: The Growth Ceiling They Can’t Break
Let’s get specific about OnBuy because this is where the opportunity is most painful. They’ve built an impressive machine:
- European expansion to 12+ countries ✓
- Comet acquisition for instant credibility ✓
- Competitive seller fees ✓
- Growing customer base ✓
But they’re stuck in transaction mode. Every sale is a new battle. Every customer acquisition costs money. Every purchase is a maybe-they’ll-come-back moment.
Here’s what happens when a customer buys pet food on OnBuy today:
- Customer finds and buys the food
- OnBuy makes one transaction fee
- Customer runs out of food in 3 weeks
- Customer goes to Amazon (because subscribe & save)
- OnBuy loses the customer forever
- The cycle repeats
Now imagine the subscription version:
- Customer finds pet food and clicks “Subscribe & Save”
- OnBuy makes a transaction fee every single month
- Customer never shops around again
- OnBuy’s customer acquisition cost plummets
- Seller gets predictable revenue
- Everyone wins except Amazon
OnBuy’s European expansion gives them the perfect subscription catalog:
- UK households needing monthly essentials
- German families buying regular household supplies
- French pet owners requiring continuous pet care products
- Spanish consumers wanting regular health & beauty items
They have the infrastructure. They have the customers. They have the products. But without subscriptions, they’re just a fancy vending machine when they could be a recurring revenue powerhouse.
eBay: The Billion-Quid Relic
eBay has the sellers, the traffic, and the trust. But their entire platform is built around 1990s thinking:
- No customer loyalty programs
- No subscription options
- No automated reordering
The Failure Model: eBay sellers spend fortunes on ads to acquire customers, only to lose them after one purchase. It’s like digging a well, taking one sip, then digging another well.
The Growth Opportunity: They could leverage their massive user base to create the largest subscription marketplace overnight. Instead, they’re letting Amazon Business eat their B2C lunch too.
TikTok Shop: The Viral One-Hit Wonder
TikTok Shop is brilliant at creating demand but terrible at capitalizing on it long-term:
- Viral products get one sales spike then disappear
- No way to turn viral moments into lasting relationships
- Creators can’t build sustainable businesses on one-off sales
The Failure Model: A creator spends months building an audience, has one viral product, makes a few thousand pounds, then has to start from scratch. It’s the digital equivalent of hunting and gathering instead of farming.
The Growth Opportunity: “Subscribe to this creator’s favorite products” or “Get this viral item monthly.” They could turn fleeting attention into recurring revenue.
Etsy: The Artisanal Gold Mine Leaving Money on the Table
Etsy is sitting on a subscription gold mine they don’t even realize:
- Monthly craft kits & supplies
- Seasonal home decor subscriptions
- Handmade skincare & soap clubs
- Artisan coffee & tea subscriptions
The Failure Model: A customer finds an amazing handmade soap seller, buys one bar, loves it, but has to manually search and reorder every time. Meanwhile, that seller’s customers slowly drift to subscription box services.
The Growth Opportunity: They could become the “Subscription Box HQ” for unique, artisanal products. Instead, they’re letting small subscription box companies steal their best sellers.
The Universal Failure Model: Why One-Time Transactions Are Killing Growth
Across all these platforms, the same broken model repeats:
- Acquire Customer (Costly) → One Sale → Lose Customer → Repeat
It’s a leaky bucket where platforms and sellers constantly pour money into customer acquisition, only to watch those customers disappear after one purchase.
The subscription model fixes this completely:
- Acquire Customer (Once) → Convert to Subscription → Keep Customer (Forever) → Profit
The Seller’s Growth Nightmare
Right now, sellers on these platforms are stuck in a growth trap:
- Constantly spending on ads to acquire the same customers
- No predictable revenue to plan inventory and growth
- Watching their best customers drift to Amazon for subscriptions
- Unable to build real business value without recurring revenue
Meanwhile, Amazon sellers with subscribe & save enjoy:
- Predictable monthly revenue
- Higher customer lifetime values
- Reduced customer acquisition costs
- Businesses that are actually sellable (subscription revenue multiples)
The Platform Revenue Rocket They’re Ignoring
Subscribe & Save isn’t just good for sellers—it’s a platform revenue machine:
- Higher take rates: Platforms could charge premium fees for subscription management
- Reduced customer churn: Subscribed customers don’t leave
- Increased advertising value: Predictable customer behavior = better targeting
- Competitive moat: Once customers set up subscriptions, they’re locked in
How They Could Dominate (The Simple Blueprint)
The implementation is straightforward but transformative:
- “Subscribe & Save 10%” – prominent placement with real savings
- Flexible scheduling – weekly, monthly, quarterly options
- Subscription management dashboard – easy skip/pause/modify
- Bundle subscriptions – “Subscribe to 3 products, save 25%”
- Creator-led subscriptions – “Get my monthly favorites” (TikTok Shop)
- Artisan subscription boxes – “Monthly handmade discovery” (Etsy)
The Moneylad Growth Verdict
The numbers don’t lie. The opportunity is massive. The implementation is straightforward. Yet OnBuy, eBay, TikTok Shop, and Etsy continue to operate like it’s 2010.
Subscribe & Save isn’t a feature—it’s the difference between building a marketplace and building an empire.
Every day they delay, Amazon gets stronger. Every month they wait, their best sellers get more frustrated. Every year they ignore this, they leave billions in growth on the table.
For OnBuy, eBay & TikTok Shop specifically, this is their ticket from being “another marketplace” to becoming “Europe’s subscription headquarters.” They have all the pieces – the European footprint, the trusted brands, the seller relationships. Adding subscriptions wouldn’t just be a feature launch; it would be a strategic nuclear weapon against every other platform.
The first platform to nail this will see seller growth explode, customer loyalty skyrocket, and revenue multiples that make investors drool.
The question isn’t if they’ll implement subscriptions—it’s which platform is smart enough to do it first. The race for mega growth is on, and right now, everyone’s losing.
