A further indication of the propensity of our customers to continue to work with and expand their relationship with us over time is our dollar-based net revenue retention rate, or NRR, which compares our revenue from the same set of active customers in one period to the prior year period. We calculate dollar-based NRR as of a period-end by starting with the revenue, defined as platform revenue, from the cohort of all active customers as of 12 months prior to such period-end, or the prior period revenue. We then calculate the platform revenue from these same customers as of the current period-end, or the current period revenue. Current period revenue includes any expansion and is net of contraction or attrition over the last 12 months, but excludes platform revenue from new customers in the current period. We then divide the total current period revenue by the total prior period revenue to arrive at the point-in-time dollar-based NRR. For the three months ending December 31, 2021 , we continued to maintain a NRR over 120% . While we have maintained this high NRR over the past three years , we expect this number to decrease over time as our customer base matures. We are also seeing a trend where customers are purchasing all of our products at signing, which provides us with more platform revenue from the start, but leaves less room for expansion. Enable Higher Transaction Volume Transaction revenue will continue to be an important source of our growth. We intend to continue to work with our existing restaurant customers to enable higher transaction volume at their locations, which may enable us to generate additional subscription and transaction revenue. As on-demand digital commerce grows to represent a larger share of total off-premise food consumption, we expect to significantly benefit from this secular trend as we capture a portion of this increased on- demand digital commerce order volume. Not only does our software create the opportunity to drive more orders for our customers, but we also expect the industry’s secular tailwinds to help increase transaction order volume as more consumers order food for off-premise consumption. As transaction volume increases, the subscription revenue we receive from certain subscription-based modules may also increase as customers subscribe for higher tier ordering packages to enable more transactions. Additionally, as we continue to expand our product offerings and improve our current software, we also believe that we may be able to increase our share of the transaction revenue that flows through our platform. Our ability to increase transaction volume is dependent on the continued shift to digital ordering for off-premise food consumption and our ability to capture a meaningful portion of that shift. Investment in Innovation and Growth We have invested and intend to continue to invest in expanding the functionality of our current platform and broadening our capabilities to address new market opportunities, particularly around payments, and data analytics. We also intend to continue to invest in enhancing awareness of our brand and developing more modules, features, and functionality that expand our capabilities to facilitate the extension of our platform to new use cases and industry verticals. We believe this strategy will provide new avenues for growth and allow us to continue to deliver differentiated, high-value outcomes to both our customers and stockholders. Specifically, we intend to invest in research and development to expand existing and build new modules, sales and marketing to promote our modules to new and existing customers and in existing and expanded geographies, professional services to ensure the success of our customers’ implementations of our platform, and other operational and administrative functions to support our expected growth and requirements as a public company. We expect our total operating expenses will increase over time and, in some cases, have short-term negative impacts on our operating margin. We also intend to continue to evaluate strategic acquisitions and investments in businesses and technologies to drive product and market expansion. Our future success is dependent, in part, on our ability to successfully develop, market, and sell new and existing modules to new and existing customers. Grow Our Ecosystem We plan to expand our current ecosystem of third-party partners to better support our customers. Our platform is highly configurable and deeply embedded into our customers’ disparate existing infrastructures. Our platform seamlessly integrates with technology providers across the restaurant ecosystem, including most POS systems, DSPs, OSPs, aggregators, payment processors, and loyalty programs. We believe that we can leverage these unique partnerships to deliver additional value to our customers. We see opportunity to further broaden our partnership group and build upon the integrations we currently offer. We plan to continue to invest and expand our ecosystem of compatible third-party technology providers to allow us to service a broader network of restaurant brands. We believe that these technology partnerships make us a critical component for restaurant brands looking to enhance their digital ordering and delivery platforms. We intend to continue to invest in building functionality that further integrates our platform with additional third-party technology providers, which expands our capabilities and facilitates the extension of our platform to new use cases and industry verticals. Our future success is dependent on our ability to continue to integrate with third-party technology providers in the restaurant ecosystem. 51
