Discover countless business opportunities and bid on hundreds of new tenders

How eSource by triSaaS works

eSource by triSaaS is designed to give suppliers optimum opportunity to win business. When buyers create a new public tender, all registered suppliers who match the criteria will receive a notification inviting them to participate. Buyers can also select private tenders which will be distributed to invited suppliers only and not listed on the public directory.

Easy as 1-2-3

Responding to a tender request is simple with eSource by triSaaS. Our user-friendly interface is designed to make each step in the process straightforward, whether you are registering and completing category information, adding users, completing the questionnaire or reviewing your bid data.

Step 1 – Register for a tender


Simply click the register button and follow the step by step instructions. We have created instructions to guide you through the entire process.

Add users

Once registered, multiple users can be created to deal with the varying aspects of a bid, from certification to compliance to price quotations.


For multinational suppliers, category managers can be added to ensure that account managers and buyers are seamlessly connected.

Step 2 – Complete the Tender


The buyer will pre-determine a wide range of questions covering topics such as insurance, legislation compliance and health and safety requirements.

Products & services

Buyers can display a number of products or services for suppliers to quote against using the easy to navigate supplier portal.

Step by Step

The intuitive solution will guide you through the question and answer process prompting you to complete all relevant fields as required.

Step 3 – Review and submit


Once you have completed the questionnaire, you will have the ability to review your data prior to formally submitting your bid.

Accurate data

eSource by triSaaS will identify potential gaps in data or items out of tolerance to minimise quoting for the wrong pack size providing useful prompts for validation prior to the final submission.


Once you are satisfied with your tender/proposal simply press the submit button. You’ll receive an email to confirm your bid has gone to the buyer.
