Virtual card adoption rate
Virtual card adoption rate measures the percentage of eligible transactions that use virtual cards rather than physical cards, manual payments, or reimbursements. Virtual cards provide stronger controls through single-use numbers, merchant locks, and predefined spend limits, making them a preferred channel for online purchases and subscription management.

What is virtual card adoption rate?
Virtual card adoption rate tracks how widely the organisation uses virtual cards for eligible purchases. Virtual cards are digital card numbers that can be generated instantly, locked to a specific merchant or spend category, given a fixed spending limit, and set to expire after a single use or on a specific date.
They offer significant advantages over physical cards for online and recurring purchases: reduced fraud exposure (compromised numbers cannot be reused), automatic spend controls (the card declines if the transaction exceeds the limit or is at the wrong merchant), and cleaner data (each card can be tagged with a cost centre, project, or GL code at creation). Organisations with high virtual card adoption typically see better spend visibility and lower fraud rates.
How to calculate virtual card adoption rate
Virtual Card Adoption Rate = (Transactions on Virtual Cards / Total Eligible Transactions) x 100
For example, if 400 out of 1,000 online and subscription transactions use virtual cards, the adoption rate is 40%. Define eligibility clearly: in-person retail purchases may not be eligible, but online purchases, SaaS subscriptions, and vendor invoice payments typically are. Track adoption by department and use case to identify where virtual cards are gaining traction and where education or process changes are needed.
How to increase virtual card adoption rate
Make virtual card creation self-service so employees can generate a card in seconds without waiting for finance approval. Pre-create virtual cards for known recurring subscriptions and assign them to the responsible team. Mandate virtual cards for online purchases above a certain threshold where the fraud protection benefit is most valuable. Integrate virtual card issuance into the purchasing workflow so the card is generated as part of the approval process rather than as a separate step. Track and communicate the fraud prevention and control benefits to build buy-in across the organisation.
