The Merchant Growth Flywheel begins with a core service that places the platform inside a customer's recurring workflow. The platform then adds tools that help that customer operate better, such as inventory management, payroll, lending, delivery, appointments, or loyalty. Better operations can increase the customer's sales and longevity, producing more core transaction volume for the platform. Greater usage also exposes customers to complementary services, some of which create additional direct revenue and make the platform harder to replace. That increased revenue funds more useful capabilities, restarting the cycle. Square's version was especially powerful because its transaction-based model allowed it to provide many tools free or cheaply: improving a merchant's business could increase Square's own revenue without charging separately for every feature.
Origin
Square expanded from card acceptance into a suite of merchant tools whose value, retention, and transaction revenue reinforced one another.
Core principles
- 01Customer growth and platform growth should reinforce each other.
- 02Add capabilities that improve the customer's core business.
- 03Monetize primarily when customers receive or create value.
- 04Use adjacent services to deepen retention and increase core usage.
- 05Evaluate features by their contribution to the whole system.
How to run it
- 1
Establish the core workflow
Win a recurring, high-value customer activity that gives the platform a durable place in daily operations.
Pro tip Choose a workflow that generates useful signals about customer health and activity.
Watch out A peripheral feature rarely creates enough engagement to drive a flywheel.
- 2
Find the adjacent constraint
Identify what prevents customers from selling more, operating efficiently, acquiring buyers, or retaining them.
Pro tip Use observed workflow data and customer interviews rather than assumptions.
Watch out Do not add unrelated features merely to expand the product catalogue.
- 3
Add a growth-enabling service
Build or integrate a capability that removes the constraint and complements the core workflow.
Pro tip Bundle the service when broader adoption improves core economics.
Watch out A supposedly free service can weaken the flywheel if its costs exceed the usage it creates.
- 4
Capture aligned value
Earn more as the customer's transactions, retention, or operational scale improves, while charging separately for services with independent value.
Pro tip Keep pricing predictable enough that customers understand the alignment.
Watch out Avoid monetization that penalizes the behavior the platform wants to encourage.
- 5
Measure reinforcement
Track whether each service increases core volume, retention, customer performance, or adoption of complementary products.
Pro tip Measure the full system effect rather than evaluating each feature in isolation.
Watch out Revenue from an add-on can conceal damage to trust or core-product retention.
- 6
Reinvest in the next constraint
Use the resulting revenue and data to identify and remove another customer growth obstacle.
Pro tip Prioritize improvements that strengthen multiple links in the flywheel.
Watch out Expansion without strategic coherence turns a suite into a confusing bundle.
In the wild
Square begins with accessible payment acceptance, then adds inventory, employee management, payroll, lending, appointments, and delivery capabilities. These tools help merchants run and grow their businesses. Increased merchant sales generate more payment volume, while selected services create additional revenue and deepen the merchant's reliance on the ecosystem.
→ Merchant success, transaction revenue, service adoption, and retention reinforce one another.
A booking platform adds automated reminders, loyalty offers, and simple working-capital advances. Providers suffer fewer missed appointments and can invest in capacity, increasing bookings processed through the platform.
→ Providers grow while the platform gains transaction volume and stronger retention.
Common mistakes
Selling unrelated add-ons
An add-on does not strengthen the flywheel unless it improves customer outcomes, core usage, retention, or another reinforcing link.
Charging at every possible touchpoint
Excessive fees can suppress the customer activity that powers usage-based platform revenue.
Ignoring unit economics
Customer growth is not automatically profitable. The platform must confirm that incremental usage and retention exceed service delivery costs.
Is it for you?
Best for
This is best for platforms whose revenue rises when customers transact more, retain users, or expand their operations.
Not ideal for
It is not ideal when customer activity creates disproportionate costs or conflicts with the platform's economic interests.

“What can we add to make the lives of small business owners easier so that number one, they stick around longer and continue to use…”
“Yeah, well, it's it's a flywheel, you know.”
“Um, but what really the beauty is in helping the merchant grow their business, which grows transaction volume, so Square makes more money, and then…”
