Doximity, the leading digital platform for medical professionals in the US, just reported another stellar quarter, exceeding revenue expectations and raising guidance. The headline numbers are impressive, but a closer look at the transcript reveals a fascinating detail that seems to have slipped past most analysts: Doximity's largest customer has quietly shifted to monthly billing.

This seemingly innocuous change in billing practices holds profound implications for how we should understand Doximity's financial performance and forecast its future growth. The ramifications are so significant that they could reshape the very way investors evaluate the company.

Historically, Doximity's deferred revenue balance has been a key metric for analysts, providing a glimpse into the company's future revenue streams. However, with the shift to monthly billing for its largest customer, this metric loses its predictive power.

As Anna Bryson, Doximity's CFO, pointed out during the earnings call, "Our largest customer will now never show up in our ending deferred revenue balance, and revenue recognition will come entirely from billings added during that same quarter." This means that a significant portion of Doximity's revenue is no longer captured in the deferred revenue balance, making this traditional metric largely irrelevant.

Think about it: Doximity's largest client, likely representing a substantial portion of their revenue, is now operating on a subscription-like model, with revenue recognized in the same quarter it's billed. This creates a much more dynamic and immediate revenue stream. It also reflects a deepening relationship between Doximity and its key clients, indicating a high level of trust and confidence in the platform's value proposition.

The shift to monthly billing offers a glimpse into Doximity's strategic vision for the future. While the company is currently focused on its core market of large pharmaceutical companies, the monthly billing model paves the way for expanding into a broader customer base, particularly smaller and mid-sized pharmaceutical companies, medical device manufacturers, and even digital health companies.

Imagine the possibilities: A self-service portal, powered by AI and real-time data, allowing a wide range of healthcare companies to access Doximity's powerful platform and tailor their marketing campaigns with unprecedented precision and efficiency. This move could unlock a vast new market for Doximity, propelling the company's growth trajectory far beyond current expectations.

Potential Revenue Impact of Expanding Monthly Billing

To illustrate the potential impact of this strategy, consider the following hypothetical scenario: Assume Doximity's largest customer, currently on monthly billing, contributes 10% to their overall revenue. If Doximity successfully replicates this model with even 10% of the remaining pharma brands with less than $100 million in US sales (currently representing only 8% of their pharma revenue), it could translate to a significant revenue boost.

While 0.88% may seem like a modest increase, it's important to remember this is just a hypothetical scenario, focusing solely on a specific segment of the potential market. As Doximity continues to expand the monthly billing model and its self-service portal to a wider range of healthcare companies, the potential revenue impact could be substantially larger.

This shift to monthly billing is a game-changer for Doximity. It not only enhances the company's financial flexibility and predictability but also positions it for accelerated growth by tapping into a vast and underserved market. The implications are far-reaching and could fundamentally alter how investors perceive and value the company.
