n8n, ZapierUnnamed 9-person B2B services firm (US Midwest) · Oct 2026

A 9-person services firm got 16 hours a week back from four AI workflows

1 · What happened

Admin time fell from 21 to 5 hours a week over a 4-week before/after; email triage alone went from 10 to 2 hours. First invoice reminder now goes out after 2 days instead of 11. No one was laid off (builder's own figures).

These numbers come from the builder and haven't been checked independently.

2 · How it works, in plain words

A builder automated email triage, quote drafting, meeting follow-ups and invoice chasing for a US Midwest services firm, and published before-and-after hours, including what didn't work.

How to do it yourself

Our suggested steps. The company didn't publish theirs.

  1. 1

    Track one normal week: how many hours go to email, quotes, meeting notes and invoice chasing?

  2. 2

    Start with the biggest one (for most firms, email triage).

  3. 3

    Connect your inbox to an automation tool and add an AI step with the prompt below.

  4. 4

    Have a person approve every drafted reply for the first weeks.

  5. 5

    Measure the same hours again after four weeks.

4 · The prompt

The instructions to give the AI

Paste this into n8n (the free plan is enough to try it), swap the [brackets] for your details, and test it on a few real examples.

This is one part of the setup. It won't connect to your phone, inbox or other apps on its own; the steps above cover that.

Agent instructions (prompt)

Read this incoming email for [business]. Label it: client request, new lead, invoice/payment, or other. Draft a short reply only for client requests and leads, using [our services and hours]. Never promise dates or prices. Flag anything urgent or unhappy for [owner].

[Highlighted] = replace with your own details before you run it.

What you should get back: Inbox sorted into 4 labels each morning, with drafted replies waiting for approval.

Possible if you are comfortable wiring tools together and testing for a week or two. If not, hire a builder: most owners do.
