The short answer
A charge from SPLIT.IO* FEATURE corresponds to feature flag management, gradual rollouts, and experimentation telemetry from Split Software, Inc. (now part of Harness).
Why it shows up like this
When corporate card statements display SPLIT.IO* FEATURE, the entry represents a recurring software subscription fee for a Split Feature Flag & Experimentation Platform account. Split Software, Inc. supplies developer infrastructure for feature flagging, canary releases, and experimental metric tracking, allowing engineering teams to decouple code deployments from production release cycles. Invoices bill monthly or annually based on active team seats and Monthly Tracked Keys.
Billing charges can fluctuate or increase unexpectedly when web applications evaluate feature flags across large user bases, causing traffic volumes to exceed contracted MTK thresholds. Annual service agreements also renew automatically unless formal cancellation notices are submitted by workspace administrators. Accessing the administrative console allows technical leads to monitor platform usage and download official tax invoices.
If you do not recognize this software expense, consult your engineering or development leads to confirm whether the platform is deployed in your technical stack. To manage subscription settings, review billing contacts, or adjust account limits, sign in to your developer dashboard online. Anyone identifying erroneous charges or unauthorized billing should contact accounting or their bank promptly.
