A CFO’s guide to profitable growth in PE-backed firms: the Rule of 40 and QTC automation

5 min read

As a financial leader in a software company that’s backed by private equity (PE) or venture capital (VC), you understand the pressure to balance rapid growth with disciplined financial health. Your investors are likely feeling this pressure, too, which has led them to shift their focus in recent years from top-line expansion to profitable growth and cash flow optimization. This shift has made the Rule of 40 a critical benchmark for PE- and VC-backed firms. 

The Rule of 40 calls for a combined revenue growth rate and profit margin that meets or exceeds 40%, indicating a balanced approach to growth that appeals to investors seeking strong returns. However, with the median growth rate in the software sector expected to drop from 16% in 2023 to just 11% in 2024, achieving this balance may be more challenging now than it’s ever been.

Quote-to-cash (QTC) automation offers a powerful way to measure and manage your performance against the Rule of 40 benchmark. By streamlining each step from sales engagement to revenue recognition, QTC automation helps you cut inefficiencies, reduce costs and scale efficiently – positioning your PE- or VC-backed company for profitable growth under a wide range of market conditions.

The far-reaching role of quote-to-cash

To put your QTC process in perspective, consider every step in the journey between an initial sales engagement and the moment you recognize revenue – from quoting, contract management and billing to collections and payment reconciliation

These steps span several departments – from sales and product to operations and accounting. They also touch multiple systems – including your customer relationship management (CRM), configure, price, quote (CPQ) and enterprise resource planning (ERP) platforms.

Now consider the complexities that can arise in each of these steps, particularly the impacts of outdated manual processes, fragmented systems and interdepartmental communication gaps. They can include:

  • Inconsistent pricing
  • Outdated discounting rules 
  • Inaccurate renewal terms
  • Missed upsell opportunities
  • Incomplete or incorrect bills
  • Collections bottlenecks
  • Reporting errors

Each issue in QTC can impact your Rule of 40 equation. One error can stifle your growth due to a lack of scalability and flexibility, while another might erode your profit margins through higher costs and inefficiencies. That’s why automating QTC is so transformative. When executed well, a QTC automation strategy not only minimizes these types of issues – it reduces your labor costs, accelerates your cash flow and keeps your team’s focus on strategic initiatives rather than time-consuming manual tasks. 

“Automation across the quote-to-cash cycle doesn’t just cut costs – it gives you the flexibility and scale you need to adapt as the market changes – a critical move for any PE-backed company aiming to hit profitability and growth targets for the Rule of 40.”

- Brad Mortimore, VP of Strategic Accounts at Zone & Co

How QTC automation drives profitability

Achieving profitable growth starts when you reduce unnecessary costs and improve operational efficiency – and that’s exactly what QTC automation is designed to accomplish. By automating key processes, you can drive substantial savings, enhance cash flow and improve customer satisfaction, all of which contribute directly to meeting the Rule of 40.

Reducing operational costs

Labor costs eat into your profit margins, especially when your finance and accounting teams handle repetitive tasks manually. With QTC automation, you can reduce these costs by minimizing your staff’s involvement in routine processes like invoicing, contract renewals and payment processing. 

Minimizing errors

Billing or invoicing errors can damage your customer relationships and reduce your renewal rates. They also take time and cost to resolve. This is particularly important for recurring billing models, where a single error can repeat and compound to damage your customer relationships. Automating your quote-to-cash process significantly reduces human error, billing mistakes, customer conflicts and churn. 

Enhancing cash flow management

Efficient cash flow management is critical for preserving your profit margins, especially in slower-growth markets. QTC automation helps you invoice on time, makes your collections run more smoothly and minimizes customer disputes. It all adds up to a better accounts receivable turnover and a more predictable cash flow. 

“Profitable growth isn’t just about survival – it’s about thriving under new conditions. For private equity-backed companies, financial discipline has become essential for maximizing value and achieving attractive exits.”

- Brad Mortimore, VP of Strategic Accounts at Zone & Co

Driving revenue growth through QTC automation

While QTC automation is essential for improving profitability, it also provides a pathway to sustainable revenue growth by bringing flexibility to pricing, solving billing complexity and uncovering new revenue opportunities.

Empowering sales with flexibility and agility

Automation gives your sales team the flexibility to implement varied pricing models, such as usage-based or subscription plans, without the need for your finance team to approve every deal. This agility is essential in winning new business in a market where personalized and sophisticated pricing models are increasingly popular.

Simplifying complex billing requirements

Billing complexities such as value-based and usage-based models can be cumbersome to manage manually. Without the right tools, partial billing periods and pro-rated services can also complicate your billing process. QTC automation makes it easy to bill quickly and accurately for even the most complicated models and scenarios, which improves customer satisfaction and prevents delays in revenue recognition. 

Preventing revenue leakage

When you rely on manual systems, revenue leakage is quite common. Missed renewals, unbilled charges, overlooked upsell opportunities and outdated contract terms can all result in lost revenue opportunities. With analysts observing decelerating growth for private software companies, it’s extremely important to capture every revenue opportunity. QTC automation prevents leakage by making sure no charge or renewal is left unbilled. 

In summary, QTC automation improves profit margins and accelerates revenue growth to impact both sides of the Rule of 40 equation.
