Why Bid for Public Sector Contracts?

Our Simple 6-Step Process to Win Your First Tender

Step 1: Get Ready to Bid

Before you start bidding:

Tip: If you’re a new business, use personal experience or voluntary work to show capability.

Step 2: Find the Right Opportunity

Look for tenders that:

Read the tender documents carefully and make sure you can meet all the requirements.

Tip: A good rule of thumb is the 33% rule, eg you can bid on tenders with an annual contract value worth up to 33% of your last years (or projected) annual turnover. Anything larger and it’s likely you’ll fail their financial checks. 

Step 3: Decide to Bid (or Not)

Ask yourself:

Tip: Don’t bid just to practice—only bid when you can deliver the contract well.

Step 4: Write the Bid

This is your chance to show you understand the buyer’s needs and can deliver.

Focus on:

Use plain, clear language and avoid jargon. Always follow the structure and word count provided.

Tip: Use graphics / charts to back up and evidence what you’ve written about. But be careful not to use them to replace word count. 

Step 5: Review and Submit

Check everything:

Tip: Submit at least a day early to avoid last-minute issues with the portal.

Step 6: Learn and Improve

If you win—great! If not, ask for feedback. This is incredibly valuable for improving future bids.
