How to Write an SOP - Step-by-Step Guide

Writing your first SOP feels intimidating — until you realise it's just:

a recipe for how your team does something consistently.

Here’s the simplest way to do it.

What is an SOP?

An SOP is:

  • documented

  • step-by-step

  • clear about who does what

  • easy to find when needed

It is NOT:

  • a policy manual

  • a legal document

  • an unread wiki nobody updates

SOP vs Work Instruction vs Checklist

  • SOP = whole process

  • Work instruction = how to perform a single task

  • Checklist = simple yes/no completion list

Most businesses need all three eventually.

Step-by-step: How to write your first SOP

Step 1 — choose the right process

Start with something that:

  • repeats often

  • causes mistakes when done wrong

  • costs time or money when inconsistent

Examples:

  • onboarding a customer

  • processing refunds

  • responding to support tickets

Step 2 — define the purpose and scope

Answer these:

  • Why does this SOP exist?

  • When should it be used?

  • When should it not?

Step 3 — list tools and prerequisites

Examples:

  • “Requires access to Xero”

  • “Customer must already have active subscription”

  • “Internet connection”

This prevents confusion later.

Step 4 — write the steps

Rules:

  • short sentences

  • numbered steps

  • action-focused

Bad:

The form should be navigated to via the portal and subsequently completed.

Good:

  1. Open the portal

  2. Click “New Request”

  3. Fill in customer name

Step 5 — add quality checks

Examples:

  • double-check email spelling

  • attach invoice file

  • confirm ID matches account

Step 6 — test with someone new

The golden rule:

If a new person can follow it, it’s a good SOP.

  • guessing formats
