For buyers contracting authority
Pick 48422000 when the purchase is a bundle of packaged software licensed together, not a single application and not a custom build. The phrase to hold onto is suite: an enterprise productivity package, a collaboration platform with its add-ons, or a multi-product licensing arrangement renewed for the whole organisation.
The boundary that trips authorities is the sibling 48421000, which is for facilities-management software packages specifically; reach for 48422000 when the bundle is broader than a single functional package. The parent 48420000 covers both shapes, so use it only when neither child fits cleanly.
One more neighbour matters. Where the bundle is squarely office productivity, document creation and scheduling tools, 48300000 is the closer match, and a suite that is really a collection of utilities can land under 48900000. Where a single contract bundles a software suite with reseller services or support, set the primary CPV code by whichever element is the dominant purpose of the contract. The recurring, renewal-driven nature of suite licensing is why the same authorities appear under this code year after year.
