Vertical integration is when a company owns two or more stages of its own supply chain, such as making a product and also distributing or selling it. Shopify says it reduces reliance on outside companies, can cut costs and lets a business respond faster to demand and market trends.
Corporate Finance Institute (CFI) frames it as bringing previously outsourced work in-house. The direction is either upstream, towards suppliers (backward integration), or downstream, towards the customer (forward integration). A company can get there by building the capability itself or by buying a business at another stage.
Backward, forward and balanced integration
| Type | Direction | Example (Shopify) |
|---|---|---|
| Backward | Upstream: suppliers and production | Zara owning manufacturing plants in Spain |
| Forward | Downstream: distribution and retail | Amazon buying Whole Foods |
| Balanced | Both directions | Apple |
Backward integration means owning raw-material suppliers or bringing production in-house. Shopify says it's capital-intensive and may cut costs in the long run, and the bigger benefit is control over material quality, sustainability and labour practices.
Forward integration moves you closer to the customer. Shopify's small business example is a jewellery seller on Etsy or Amazon who gives up part of every sale in exchange for access to buyers there. Opening its own online store gives it control of sales, distribution and marketing, a better customer experience and higher margins. That's forward integration at a scale any small business can manage.
Balanced integration does both. Shopify says it's less common and needs careful strategic planning and serious capital. Its examples are a mid-sized coffee company that owns or partners with coffee farms and runs its own coffee shops, and Apple, which designs its own hardware and software, makes key components and sells through its own stores.
Four degrees of integration
Integration isn't all or nothing. CFI describes a scale:
| Degree (CFI) | What it looks like |
|---|---|
| Full vertical integration | The company owns the stage outright |
| Quasi integration | The company holds a stake in a supplier |
| Long-term contracts | A diluted form of integration |
| Spot contracts | Not integrated at all: buying as needed |
The catch: SpaceX built it in, McDonald's chose not to
CFI's sharpest example is the cost of a rocket launch. SpaceX makes most of its components in-house, and CFI puts its cost at $90 million a launch. United Space Alliance, a Boeing and Lockheed Martin partnership, cost about $460 million a launch, because its dispersed suppliers each added their own cost plus a margin. These are CFI's US dollar figures, as of October 2026.
But CFI also shows the opposite choice working. McDonald's runs a franchising model with a dispersed supply chain. It keeps that chain in line through communication and a crowdsourcing platform where suppliers share ideas. Integration is one way to control a supply chain; it isn't the only one.
CFI names the main downside as managerial complexity: every new stage you own needs expertise you may not have. Its example is Exxon Mobil weighing up convenience stores alongside its gas stations. On the plus side, CFI says integration reduces the bullwhip effect, where small changes in customer demand get amplified as the information passes back along a chain of separate companies.
The pros and cons side by side
| Pros (Shopify) | Cons (Shopify) |
|---|---|
| More control over quality and timing | High initial investment |
| Cost savings from cutting out the middleman | More complex management |
| Better coordination between stages | Less flexibility to change suppliers |
| A competitive advantage that's harder to copy | Possible inefficiency outside your core skills |
| A better customer experience | Regulatory risk if it looks anti-competitive |
Vertical vs horizontal integration
Shopify draws the line clearly. Horizontal integration means merging with companies at the same stage of the supply chain, to grow market share and reach economies of scale. Its example is Meta buying Instagram and WhatsApp. Vertical integration means owning different stages of your own chain.
How to plan it in four steps
Shopify sets out a four-step process:
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
- Identify integration points: look at how much you spend on outsourcing, plus factors such as sustainability.
- Decide whether to acquire a current supplier or build the capability yourself.
- Integrate and streamline: align working practices and IT systems.
- Coordinate and adjust: review control, cost and flexibility regularly.
Before you bring anything in-house, it's worth reading the other side of the argument in my piece on why startups should outsource critical processes. And if you want to see vertical integration as a brand story, my breakdown of Zara's marketing strategy shows how owning production lets it move fast.
Where I come in
For most small businesses and SaaS marketing teams, the most useful stage to own isn't a factory. It's the relationship with the customer. Renting reach on someone else's platform is the marketing version of outsourcing distribution. I've spent 23 years in marketing, and I help businesses build their own audience channels, such as an email list and a site that ranks, so they rely less on platforms they don't control. You can see how I work on my work with me page.
My verdict
Owning more of the chain buys you control, and it costs you flexibility and management time. For a small business, the sensible first step is usually forward, not backward: open your own store alongside the platforms you sell on, and own the customer data. Leave backward integration until you know exactly which supplier cost is hurting you, and that you could do it better.
Owning the chain can also keep rivals out, which links to how barriers to entry work.
Frequently asked questions
What is vertical integration in simple terms?
It's when a company owns two or more stages of its own supply chain, such as making a product and also selling it.
What is the difference between backward and forward integration?
Backward integration moves upstream towards suppliers and production. Forward integration moves downstream towards distribution and the customer.
What's an example of vertical integration?
Shopify's examples include Zara owning factories in Spain, Amazon buying Whole Foods, and Apple designing, making and selling its own products.
What is the main disadvantage of vertical integration?
CFI says it's managerial complexity, because every new stage needs expertise the company may not have.
How is vertical integration different from horizontal integration?
Horizontal integration merges with companies at the same stage, such as Meta buying Instagram. Vertical integration owns different stages of one chain.
