Bid Writing Services: a comprehensive overview

An Introduction to our Bid Writing Services

‘Bid writing services’, the support offered by professional bid writers, are increasingly in demand by those looking to grow their businesses through winning tenders.

Professional bid writers play a crucial role in the competitive world of contract bidding, especially with small and medium sized businesses who do not employ their own bid writers, instead choosing to outsource the requirement due to the peaks and troughs of tendering.


At Thornton & Lowe, we specialise in helping our clients win government tenders and public sector bids, which has led to our bid writing services being developed specifically to meet the requirements of this market.

We have provided our clients with a range of bid writing services since 2009, helping them achieve, on average, a bid win rate over 75%. If you are require a bid writing quote or you are looking to win more public sector contracts – Contact us now.

Tender Writing Services

Tender writing services and bid writing, for us, are exactly the same. Thornton & Lowe’s tender writing services allow our clients to outsource their tender writing requirements and more effectively manage the often time consuming role.

When responding to a formal procurement opportunity or tender, there are often detailed quality questions, which require a specific and competitively written response in order to maximise the scores available. Our tender writers work tirelessly to maximise your quality scores and help your business win more public sector contracts.

When it comes to offering tender writing services you need to have a complex mix of skills, experience and knowledge. Including procurement, tendering, persuasive writing, sales and marketing. This combination allows our tender writers, and the wider bid team, to work closely with our clients, using their technical knowledge and experience, to make the bid shine!

As well as tender writing consultancy, our wider tender writing services include bid and tender writing courses and free guidance and advice.


Why use Bid Writing Services?

There are many reasons that businesses look to use outsourced bid writing services to help them win tenders. The main reason businesses engage with Thornton & Lowe’s bid writing services is specifically to compete for and win public sector tenders. Though we still support some of our clients with private sector tenders.

For SME businesses tendering can be a real nuisance! Our clients are usually comfortable with tender pricing but need a consistent team available for PQQs, ITTs, RFPs, portal management, tender monitoring, bid management, writing and coordinating the tender bid submissions. These are the core areas of our bid writing services. Effectively, our bid team becomes your outsourced bid writing team!

Businesses use outsourced bid writing services due to the peaks and troughs of the required workload, combined with a lack of:

  • Bid writing or management capacity.
  • Bid or tender success.
  • Tendering expertise.
  • Public sector procurement expertise.

Bid writing consultants free up essential time for businesses to focus on core operations while bringing in expertise that might not be available in-house. By entrusting bid writing tasks to external experts, businesses can allow their internal teams to concentrate on core activities, ensuring smooth operation of their main functions without the added stress of complex bid processes. This strategic shift not only saves time but also enables more effective resource distribution, ensuring every part of the business gets the focus it needs.

The financial implications of keeping full-time, in-house bid writing staff can be substantial, especially in a market with a severe lack of quality and professional bid writers. Outsourcing offers a cost-effective alternative by removing the need for long-term employment commitments and the associated expenses and challenges such as salaries, holidays, benefits, quality assurance and training. Businesses can use bid writing services on an as-needed basis, which allows for better budget control and flexibility, making it an economically viable option particularly for projects with fluctuating demands.


Employing outsourced bid experts can significantly improve the quality of bid submissions, enhancing work winning strategies. These professionals possess a understanding of industry-specific knowledge and best practices in bid preparation, leading to more innovative ideas and stronger bids. Their external viewpoint can provide invaluable insights and highlight potential bid weaknesses. Through their specialised skills and structured processes, these consultants not only boost the quality of bids but also enhance the chances of success, aiding businesses in securing more contracts and achieving growth.

Put simply, a company seeking bid writing services is looking to win more. They are looking to increase their return on investment through engaging with government tenders. A professional bid writing consultancy, such as Thornton & Lowe, will have a proven system to help them achieve this.

Choosing the Right Bid Writing Service

Partnering with the right bid writing services provider or bid management consultant is an important decision for any business owner or management team. The bid writing services market has a severe shortage of professional writers and bid managers, which can make finding the right partner a challenge. This is especially the case for those businesses who are familiar with using a single freelance bid writer. When available, they can be great, but this often can be a struggle for those looking for a consistent service.

15 years ago Thornton & Lowe reviewed this challenge, and developed a solution to meet client requirements; providing a consistent service and the same professional bid writers, but available only when required. These bid writers get to understand your business, create efficiencies in the bid writing process and make a real impact on your bid strategy. This is why our Bid Success Partners win more tenders, when compared to our adhoc or non-contracted clients. Our Bid Success Programme offers our full range of bid writing services and at reduced rates.

When selecting the ideal bid writing service, it's crucial to evaluate how it best fits your business needs.

Tracy Hutchison, Director, Elite Entrance Systems

Bid Writing Services Evaluation Criteria

  1. You get on! They take the time to understand your business in a timely manner and demonstrate their value.
  2. You understand their systems for working with clients, for collecting information, working with your team – and you like it. And can see it working in practice for your business.
  3. Reviews, testimonials and bid writing services case studies offer reassurance. You want a proven bid writing partner who can demonstrate they can deliver.
  4. Transparency is key. If you ask an honest question, do you get an honest answer?
  5. Bid writing experience with clients who are similar to you. At Thornton & Lowe we work with a lot of SME businesses who often have different needs and expectations when compared to those who are more familiar being part of a larger bid team, for example.
  6. Are the bid writing prices fair and work within your budget?

Evaluating the ROI of Bid & Tender Writing Services

One of the benefits of using outsourced bid writing services is that they should come with existing performance reporting systems for monitoring bid success. We aim for full transparency with our clients which starts with benchmarking existing performance, tender feedback and bid win rates. Breaking this down, wherever possible, based on service and customer type so the impact of our bid writing services are clear.

As well as providing a summary of the time spent on projects each month (pre-approved by our client for budget control) our standard report includes the corresponding win rates for each bid writing project. This gives the cost of bidding, the result and value of the contract.

ROI encompasses not just the direct profits from successful tenders but also the wider business impacts, such as improved reputation and strategic positioning.

There are also less formal ways of evaluating the performance of your bid writing services provider. Are they easy to work with? Do they save your team time? Have you found and secured opportunities you would have normally missed?

And of course, bid writing for public sector contracts is one of those few areas in professional services or consultancy where there is nowhere to hide! Tender feedback provides details on how you performed on each tender. How does it compare prior to their engagement?


The Process of Working with a Bid Writing Service

The journey of collaborating with a bid writing service begins with a discovery session where both the client and the consultancy dig into the specifics of the upcoming tender. We need to understand about your business, how it operates, how you will deliver the specific tender live tender, what other contracts you have, your policies and procedures. This initial meeting is crucial as it sets the groundwork for understanding the project scope, client expectations, and the strategic approach required. It is also when we agree internal deadlines and key project dates. Following this, the team conducts a thorough assessment of the tender documents and shares a detailed gap analysis. This tool becomes part of our bid tools for the live tender which allows us to share progress. We ask for facts, figures any evidence you have which is shared via interviews, meetings and passing of documents.
