IT people love acronyms. Your clients might not.

You didn't get into IT to become a translator. If you've ever had to rephrase "we need to patch the RMM" into something a client can understand, you know the struggle that acronyms can bring to a conversation.

Help your team and your clients stay on the same page and have productive discussions with our free guide to IT and tech acronyms.

This quick-reference glossary helps you: 

  • Gain a quick refresher for less common tech terms
  • Hand clients a resource instead of hoping they understand a problem
  • Speak the same language across IT management, security, and planning
  • Onboard junior techs faster with a shared point of reference
  • Build client trust by inviting them into the conversation

Less time explaining. More time doing the work.

At LayerCake, we believe good IT support means things are explained clearly rather than hidden behind acronyms.

Use this glossary as your own quick reference, or pass it along to a client who might get frustrated when they feel lost in a conversation. Either way, it'll make tech feel less intimidating for everyone involved.
