Should you build or buy AML Transaction Monitoring & Suspicious Activity Reporting?

The decision turns on your transaction mix, risk profile, and ability to maintain detection, investigation, filing, and model governance. A vendor can support those obligations; the institution still needs to establish that the configured system meets them.
Build it, buy it, or bridge?
When building makes sense
Consider an internal build for transaction-specific features, detection models, or alert triage. Independent production builds exist in a limited set of institutions. Vendor AI products are not evidence that a buyer has built the equivalent core.
When buying makes sense
Buying earns its keep when you need monitoring coverage, case workflow, filing, validation, and audit support. Compare the vendor’s coverage with the staff, integrations, and controls an internal option would need. Custom extensions can remain useful without replacing the core.
