Verity AI In Action

Real customer use cases demonstrate how Verity AI reduces manual effort, increases accuracy, and surfaces risk across critical accounting workflows.

Accruals

Intelligent Accrual Estimation

SCENARIO:

A retail enterprise was reliant on manual accrual estimates for vendor rebates and pending invoices. Month-end estimates deviated 8-15% from actuals.

AGENTIC SOLUTION:

Verity Accruals agentically automates the end-to-end process: unifying data across financial systems like ERPs, AP, P2P, confirms the details with vendors, and calculates the accrual amount.

OUTCOME:

Reduced time spent on the accruals process by 80%+, increases financial statement accuracy, and provides a complete, AI-driven audit trail.

AI-Powered Account Preparation

SCENARIO:

Accountants are spending excessive time on manual, repetitive work of preparing complex reconciliations, creating bottlenecks in the financial close process.

AGENTIC SOLUTION:

Verity Prepare agentically analyzes complex documents, performs data grouping and aggregations, and drafts reconciling items with explanations for review.

OUTCOME:

Manual preparation time is drastically reduced, (by up to ~95%), allowing teams to focus on strategic review and final approval.

64%

Autonomous Transaction Matching

SCENARIO:

Organizations handling high volumes of complex transactions with messy, unpredictable data generates many unmatched transactions that require tedious manual investigation to match.

AGENTIC SOLUTION:

Verity Match uses AI-powered pattern recognition to resolve complex and inexact matches, learning from historical data rather than relying on rigid rules

OUTCOME:

Maximizes manual processing efficiency by significantly increasing match rates, accelerating the close, and transforming the user workflow from manual investigation to rapid review and confirmation.

avg. reduction in residual unmatched rates

Agentic Collections s AI Assisted Resolution

SCENARIO:

A global financial services firm struggled to collect from 500+ customers with balances too low to warrant painful manual collection efforts.

AGENTIC SOLUTION:

Verity Collect's voice agent automates collections by placing natural-sounding calls for outstanding invoices. It transcribes the conversation, logs outcomes like a "promise to pay," and automatically drafts follow ups.

OUTCOME:

Early results showed that the agent completed collections outreach in under 30 minutes, a task that would have taken an estimated 45 FTE-hours.

11 Note: Customer outcomes above represent preliminary results from select early adopters of BlackLine's Verity AI products.

Growing Momentum in Platform Pricing

As we successfully attract new customers and migrate existing ones to our platform pricing, we expect a growing portion of our ARR to come from this model, leading to a planned decrease in paid user counts.

17 eligible ARR as total annual recurring revenue, excluding revenue from SAP solutions-extensions ("SolEx") and the public sector.

ARR by Customer Cohort (Enterprise Customers)1

Cohort

Growth Multiple

ARR by Customer Cohort (All Customers)1

Cohort

Growth Multiple

1 Reflects annualized subscription and support revenue for the group of enterprise customers that became our customers in each respective cohort year. A "cohort" is a grouping of enterprise customers by the year specified. For instance, the 2012 cohort includes all enterprise customers whose contract start date is between January 1, 2012, and December 31, 2012. We calculate annualized subscription and support revenue at a particular date as the total amount of minimum subscription and support revenue contractually committed under each of our customer agreements for that month through the remaining term of the agreement, divided by the remaining number of months in the term of the agreement, multiplied by twelve. We calculate initial annualized subscription and support revenue for any given cohort year as the sum of annualized subscription and support revenue as of the first month of each customer agreement that was entered into within that given cohort year. Accordingly, in contrast to annualized subscription and support revenue, initial annualized subscription and support revenue does not reflect any changes in the payments due under or for the duration of customer agreements following the first month of the customer agreement. Our annualized subscription and support revenue as of March 31, 2026, for our customer cohorts for each of

18 the years 2012 through 2025 represented an increase over the initial annualized subscription and support revenue for such customer cohorts, shown as the "Growth Multiple" above.
