  • Improve your proposal and tender win rates
  • Land better, more profitable business
  • Delight clients by consistently exceeding expectations
  • Make bidding easier and more effective for you


Our mission is to optimise the return on investment already made in your Bid Teams and corporate sales functions by winning more business for you.

We do this in three ways. Firstly, by providing short term live bid support for your “must win” deals. Secondly, by helping you build better longer-term strategies, processes and teams for sustainable success. And thirdly, by delivering focused, tailored workshops to bolster capability.The results? The Winning Proposal’s clients are better equipped to win more bids and secure the business required to fuel your growth.


We want you to win more business by becoming more effective in the way that you develop proposals and to be more impactful when presenting solutions to prospects face-to-face.

Sometimes you might just need some hand-holding and focused support for a particularly important bid.

Or perhaps a comprehensive root and branch review and complete overhaul of your bidding strategy and processes may be required?

Either way – telling tweaks vs systemic overhaul – you will demand that we work alongside your team in a true value-adding partnership.

Here at The Winning Proposal we pride ourselves on our professionalism, client-centricity and our commitment to meet your business objectives by increasing the win rate of your bids and proposals.

These values and our commitment to your success are evidenced by our desire to enter into gain-sharing agreements with our clients, thereby explicitly tying our rewards to yours.

We are in this together!

Our values are:

  • Total dedication to deliver the best sales results for our clients
  • To consistently meet and exceed your expectations
  • To develop long-term mutually beneficial relationships with you
  • A commitment to transform your sales revenues and profitability
  • Our success = your success
