A Smart Group Company
Every direct authorization DEL holds is published here as a certificate card — brand, authorised scope and a live validity badge — so buyers, auditors and tender committees can confirm the relationship before they award. The paper itself is issued on request for submissions.
One certificate card per direct principal. The reference follows DEL’s internal certificate register; the scope states exactly what DEL is authorised to sell and support, and the badge shows the current validity status.






Validity badges reflect the register at publication. For a live confirmation letter or the physical certificate to attach to a tender submission, request it through your Partner Manager or the contact below — letters are issued per submission.
Each card in the register above is a signed principal-to-DEL relationship — not a reseller handshake. Four terms govern every certificate DEL tenders against.

The register sorted by vintage — eight principal relationships held since 2016 or earlier, each renewed continuously from the year it began.

IBM10 yrs in forceAuthorizations are the highest-value document in a tender, so DEL makes them easy to confirm independently.
Match the brand and scope on the certificate card above against what the tender requires.
Note the certificate reference (DEL-AUTH-…) shown on the card.
Request a dated confirmation letter — DEL’s channel desk issues it to the buyer or committee directly.
A confirmation letter is issued to the requesting buyer or tender committee, not routed through a third party, so the awarding body hears straight from DEL.
Tell DEL which tender and which brands, and the channel desk prepares the authorization letters and confirmation on the same business day.
Existing partners pull current certificates directly from the portal.
