Part 1 The problemWhy teams need this

01 · THE PROBLEM

When support lives in three inboxes, urgent tickets wait behind easy ones and easy ones wait for a human. One router clears the routine questions, around 40% of the volume, and gets the rest to the right person fast.

Part 2 How it worksWhat it does, step by step

02 · WHAT IT DOES

Every support message, wherever it arrives, becomes one ticket. AI sorts it by urgency and topic, answers the routine how-to questions from your help centre, and sends everything else to the right team in Slack with the SLA clock already running.

03 · HOW IT RUNS

Step by step, as built.

  1. One ticket shape

    Email, chat and WhatsApp messages are normalised and merged.

  2. Classify

    Each ticket is sorted: urgent, how-to, billing or other.

  3. Answer what's routine

    An agent answers how-to questions from the help centre, and only a confident answer is sent.

  4. Escalate the rest

    Urgent, billing and uncertain tickets go to the right team in Slack.

  5. Track the SLA

    Every ticket is logged with its SLA clock; a check every 15 minutes escalates tickets close to breach.

04 · WHERE A PERSON STAYS IN

The machine drafts. A person decides.

The AI only replies when it's confident. Every other ticket goes to a person, with the SLA clock visible.

06 · WHEN SOMETHING BREAKS

Failure is designed in.

  • 8nodes retry automatically when an external API fails.
  • 1decision point (IF or Switch) checks the data before it moves on.
  • ✓Anything unhandled triggers our central error workflow, so a crash gets reported instead of failing silently.

Standard on every build

  • Schema validation before downstream writes
  • Retry and error routes for external API failures
  • Duplicate-safe processing and idempotent updates
  • Human approval where the action carries business risk
  • Execution logging for support and audit review

Part 3 The impactWhat it's worth, and how we'd build yours

07 · PROJECTED IMPACT

What it should change in the business.

Projections for a typical deployment. The calculation below shows the math, and you can put in your own numbers.

08 · ROI CALCULATION

How it pays back in your business.

The starting numbers are a hypothetical deployment sized to the projections above. Change any of them to your own volumes and costs, and the math updates underneath.

$53.3

The math: 3,000 support tickets × 8 min × 12 months × 40% ÷ 60 = 1,920 hours a year × $40/hour = $76,800. Net value = gross value − $1,440 running cost a year.

09 · HOW WE'D BUILD YOURS

How we'd build yours.

  1. Discover: map the current process, systems, volumes, owners and exceptions.
  2. Design: define the canonical data model, approvals, retries and system boundaries.
  3. Build: implement credentials, nodes, validation and observable error routes.
  4. Prove: run controlled data through success, duplicate and failure scenarios.
  5. Operate: publish runbooks, ownership and measurable service levels.

SAME SYSTEM

Built for the industries we serve.

Reference architectures for legal, accounting, insurance, customer support and venture capital teams. Each one is a complete n8n workflow, with a person kept in the loop wherever the risk is.
