What you'll build

Real portfolio pieces built during the course, not a certificate for its own sake. Each one is work you can show.

  • Case log with tone notesTen cases written to a consistent standard: the customer's own words, the channel, what was done, and a short note on how the tone was handled, including at least one de escalation and one honest no.
  • De escalation scriptA one page script covering the acknowledge, get to facts, act, and follow up pattern, with sample lines for phone and for chat, and the phrases to avoid.
  • Billing and order issue runbookA procedure for the four most common billing and order situations: wrong charge, refund outside the normal window, item never arrived, and disputed subscription renewal, each with what to check first.
  • Shift handover noteThe end of week handover from the simulated shifts, covering open promises, anything close to breaching a response target, patterns worth watching, and an honest queue count.

Description

Every CertClue course follows the same seven-part shape: fundamentals, the role translated out of job-posting language, a real working day, the job's recurring rhythms, a multi-day simulation, the portfolio you build along the way, and a handoff into your next move. Here is what that looks like for customer service representative.
