How Scalability uses Hyperline to unify their billing processes

From agency to product, with pricing to match

Scalability is a growth-as-a-service provider that streamlines and automates sales processes, identifying suitable prospects at the right companies and engaging them to generate additional revenue. It supports startups and scaleups with outbound prospecting, from market data research to automated outreach leading directly to meetings, and serves customers such as Karmen, Brevo, PlayPlay, and GLS.

The business started as an agency, expanded into professional services, and is now evolving toward a SaaS-based model. Pricing followed the same path: from a service-first approach to a balanced 80% product and 20% service offering. Today, Scalability sells a standard plan that provides core value, with modular add-ons and sales team licenses that unlock credits. The strategy went through frequent adjustments before stabilizing, then increased with added features; for 2025, the team is considering a fully usage-based credit system.

To run all this, Scalability relied on Pennylane's billing module to invoice clients, and soon added Oneflow to handle quotes.

A quote-to-cash process split in two

The two tools were disconnected from each other and from the product.

“Our sales teams had to enter the information once in Oneflow for quotes and then again in Pennylane to start subscriptions and generate invoices. It was extremely time-consuming and prone to errors.”

Pennylane’s module also fell short of Scalability’s needs for dynamic pricing, pre-paid credits, and multi-phase subscriptions. Coupons were a particular pain point: the team’s advanced needs required far more flexibility to manage many coupons in parallel. And the lack of essential integrations, such as with their CRM Salesforce, kept teams from managing subscriptions from their primary business tools.

Choosing Hyperline

At the end of 2023, Benjamin, CEO of Scalability, and his team decided to change tools to simplify daily tasks for the Sales, Finance, and Operations teams. During their benchmark, they quickly turned to emerging billing solutions.

“We had heard about the gaps and frustrations created by the leading market tools, and it aligned with the company’s DNA to choose an early and innovative solution!”

The shortlist came down to Hyperline and Lago. Beyond the product features that best matched their use cases, Scalability is bootstrapped and was particularly sensitive to pricing: they wanted a solution with fair, transparent pricing that could scale with them. Convinced by Hyperline’s integrations, its flexibility in managing coupons and subscriptions, and its pricing, they committed in January 2024.

Onboarding was handled directly by the revenue teams, including Benjamin, without any developer involvement, and the support team’s responsiveness kept the transition smooth.

“Onboarding was really quick, it was honestly fast and we didn’t have to do much.”

One place for quotes, subscriptions, and invoices

Creating quotes, managing subscriptions, and generating invoices now all happen in the same place, which Benjamin describes as a total game changer.

“Since Hyperline, our teams perform the operations more seamlessly, and all data is available from one stage to the next in the customer account. It changes everything!”

The Salesforce integration lets Sales teams manage their customer accounts independently, from generating quotes to sending invoices. Thanks to the widget, they use every feature they need from their usual tool, without direct access to Hyperline. Having all billing data in one place gives a clear view of active subscriptions and contracts awaiting signature, and the flexibility of the coupon catalog has simplified the billing experience for the sales teams.

Adopting Hyperline allowed Scalability to unify its billing processes, reduce redundancies, and improve accuracy: a single source of truth that supports the company’s ongoing growth and simplifies daily operations for its teams.
