For buyers contracting authority
Pick 72311100 when the deliverable is converted data: scanned and indexed documents, vectorised plans, a migrated dataset, or media transcoded into a usable digital form. The cleanest test is whether the accepted output is the same information in a new shape. If it is, this is the code.
The boundary that trips contracting authorities is the sibling Batch processing services (72311200), which runs data through a defined pipeline on a schedule rather than transforming it once into a new format. Where the contract is a recurring processing operation, that sibling fits better; where it is a one-off conversion of an existing store, stay here.
Watch two further neighbours. Document digitization that an authority frames primarily as a scanning service sometimes lands under document-management codes instead, and geospatial vectorisation occasionally rides under mapping codes. With 144 awards across the full window (TED 2009-2026), this is a thinly used leaf, so tag by the dominant deliverable and accept that many authorities default upward to the broader tabulation parent.
