Purchasing SOP

Uncontrolled purchasing shows up as surprise spend and untraceable invoices: two people order the same thing, or one person orders something no one approved. This template puts an approval step exactly where the money leaves, and a record that ties every invoice to a request. It is written for small teams where one person wears the finance hat. The worked example follows the purchase of a replacement laptop from request to payment. The rule that keeps it honest is simple: no approval, no purchase — and the record is the thing that lets you check.

Worked example

1

Purpose

Note — One sentence on why this procedure exists.
Change bar — replace this

To make sure every purchase is requested, approved and recorded before money leaves, so no invoice is untraceable and no spend is unauthorised.

2

Scope

Note — What this covers and what is out of scope.
Change bar — replace this

All purchases above fifty dollars, and any purchase on company account. Petty cash under fifty dollars follows the cash log instead.

3

Request

Note — How a need becomes a request.
Change bar — replace this

A written request states what is needed, why, the rough cost, and the date it is needed by. A verbal request is not a request.

4

Approval

Note — The step where money is authorised.
Change bar — replace this

The owner approves any purchase over fifty dollars; the requestor cannot approve their own purchase.

5

Order and receipt

Note — Placing the order and checking what arrives.
Change bar — replace this

Only an approved request is ordered, by the person named on it, from the supplier named on it.

Change bar — replace this

On arrival, the goods are checked against the order — correct item, quantity and condition — before the invoice is accepted.

6

Invoice and payment

Note — Tying the invoice to the request and paying it.
Change bar — replace this

The invoice is matched to its approved request and receipt before payment, then paid on the next scheduled payment run.

7

Records

Note — Where the purchase record lives.
Change bar — replace this

Purchase records — request, approval, order, receipt and invoice — are filed together and kept for the current tax year.

These documents are starting structures for you to build on, not professional or legal advice. Anything that will have legal or contractual effect, or that varies by jurisdiction, should be reviewed by someone qualified in the relevant place.

Why this process gets written down

This procedure is written because the task is repeated, it matters when it goes wrong, and it should not depend on one person's memory. The worked example above shows the same structure filled in for a real case, so you can see what a complete version looks like before you write your own.

The Document Control Kit

Turn a folder of documents into something a team can actually find and follow

Every template on this site is free and stays free. The kit is what turns a folder of documents into a system you can actually run: a register with numbers, owners and review dates; who reviews what and how often; a numbering scheme that still works at fifty documents; and the thirty-day sequence for getting a team to use any of it, which is where most of these projects die.

What the kit holds

Register Column headings — number, title, owner, revision, approval date, review-due date
Review cadence Who reviews what, how often, and what triggers an off-cycle revision
Rollout plan The thirty-day sequence for getting a team to actually use the documents
Numbering scheme How to number documents so the system survives its first fifty
