Most treasury tools pick a lot-accounting method once and apply it forever. Every disposal, every transfer, every reporting period inherits a default the vendor chose, and the finance team never sees the alternative outcome sitting right next to it.
That default is itself a strategic decision. It is just usually made by the software, not by the treasury team that has to defend the result.
Bedrock treats lot selection as a policy you control. The same transaction can produce a materially different, fully documented outcome depending on the rules your team sets, and the record preserves why each outcome is what it is.
