Disclaimers 2 | © 2022 BTRS Holdings Inc. dba Billtrust. All rights reserved. Forward-Looking Statements This presentation includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “target,” “expect,” “believe,” “will,” “explore,” “forecast,” “outlook” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding Billtrust’s financial outlook/guidance and estimates and forecasts of Billtrust’s financial and performance metrics, the potential benefits, value and the commercial attractiveness to its customers of Billtrust’s products and services, Billtrust’s opportunity and ability to grow and scale its business, Billtrust’s technology platform, and Billtrust’s ability to execute its social responsibility and sustainability initiatives. These statements are based on various assumptions, whether or not identified in this presentation, and on the current expectations of Billtrust’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and may differ from assumptions. Many actual events and circumstances are beyond the control of Billtrust. These forward-looking statements are subject to a number of risks and uncertainties, including Billtrust’s ability to attract and retain customers and expand customers’ use of Billtrust’s services; market, financial, political and legal conditions; the impact of the COVID-19 pandemic on Billtrust’s business and the global economy; risks relating to the uncertainty of the projected financial and operating information with respect to Billtrust; risks related to future market adoption of Billtrust’s offerings; risks related to Billtrust’s marketing and growth strategies; risks related to expanding Billtrust’s operations outside the United States; risks related to Billtrust’s ability to acquire or invest in businesses, products, or technologies that may complement or expand its products or platforms, enhance its technical capabilities, or otherwise offer growth opportunities; the effects of competition on Billtrust’s future business; and the risks discussed in Billtrust’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 filed March 9, 2021, under the heading “Risk Factors” and other documents of Billtrust filed, or to be filed, with the Securities and Exchange Commission (“SEC”). If any of these risks materialize or any of Billtrust’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that Billtrust presently does not know of or that Billtrust currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, these forward-looking statements reflect Billtrust’s expectations, plans or forecasts of future events and views as of the date of this presentation. Billtrust anticipates that subsequent events and developments will cause Billtrust’s assessments to change. However, while Billtrust may elect to update these forward-looking statements at some point in the future, Billtrust specifically disclaims any obligation to do so. These forward-looking statements should not be relied upon as representing Billtrust’s assessments as of any date subsequent to the date of this presentation. Accordingly, undue reliance should not be placed upon the forward-looking statements. Non-GAAP Financial Measures Some of the financial information contained in this presentation has not been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). Such financial information is identified as such within the presentation. Billtrust believes that the use of these non-GAAP financial measures provides an additional tool for management and investors to use in evaluating Billtrust’s actual and projected financial condition and operating results and trends in and in comparing Billtrust’s financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. Billtrust does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and other amounts that are required by GAAP to be recorded in Billtrust’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and other amounts are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, Billtrust presents non-GAAP financial measures in connection with GAAP results. Billtrust is not providing a reconciliation of its projected non-GAAP adjusted gross profit, non-GAAP adjusted gross margin and non-GAAP adjusted EBITDA for 2021 to the most directly comparable measure prepared in accordance with GAAP because certain items excluded from non-GAAP adjusted gross profit and non-GAAP adjusted EBITDA, such as charges related to stock- based compensation expenses, the change in fair value of contingent consideration related to an acquisition and related tax effects, including non- recurring income tax adjustments, cannot be reasonably calculated or predicted at this time. You should review Billtrust’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 filed March 9, 2021, under the heading “Risk Factors,” and other documents of Billtrust filed, or to be filed, with the SEC.

Supplier Buyers and suppliers need a better way to connect 10 | © 2022 BTRS Holdings Inc. dba Billtrust. All rights reserved. It’s very difficult for buyers and their AP partners to find and pay suppliers electronically, and it’s similarly hard for suppliers to accept and handle those electronic payments “What are these payments truly costing us?” “Why are these customers paying late?” “How will we process their remittances?” “Should we participate in these programs?”

Definitions Net Revenue (non-GAAP) is defined as total revenues, less reimbursable costs revenue. 29 | © 2022 BTRS Holdings Inc. dba Billtrust. All rights reserved. Adjusted Gross Profit (non-GAAP) is defined as total revenues less total cost of revenues, excluding depreciation and amortization, plus stock-based compensation expense included in total cost of revenues. Adjusted Gross Margin (non-GAAP) is defined as adjusted gross profit divided by total revenues less reimbursable costs revenue, or net revenue (non-GAAP). Adjusted EBITDA (non-GAAP) is defined as net loss, plus (1) income tax expense (benefit), (2) the change in fair value of financial instruments andother income (expense), including the change in the fair value of liabilities (for Earnout Shares, warrants, contingent consideration, or other equityinstruments classified as liabilities), (3) interest expense and loss on extinguishment of debt, (4) depreciation and amortization, (5) stock-basedcompensation expense, (6) restructuring and severance costs, (7) acquisition and integration costs, and (8) other capital structure transaction costs,minus (9) interest income.

Direct Card Revenue (“DCR”; non-GAAP) includes variable transactional fee revenue associated with card payments on our electronic payments processing platforms. Direct Card Revenue is a subset of our overall Software & Payments Revenue. Card Yield (bps) is calculated by dividing (i) Direct Card Revenue for the current period divided by (ii) Card TPV for the current period. Card Total Payment Volume ("Card TPV") is a subset of our Total Payments Volume ("TPV"). Software and Payments (ex-DCR) Revenue (non-GAAP) is calculated by subtracting (i) Direct Card Revenue (non-GAAP) from (ii) Software and Payments segment revenue. Direct Card Revenue Per Transaction (non-GAAP) is defined as Direct Card Revenue (non-GAAP) divided by the number of customer card payments that Billtrust processes on its platforms during a particular period, all of which are included in Card TPV. Total Payment Volume (TPV) is defined as the dollar value of customer payment transactions that Billtrust processes on its platform during a particular period.
