The Biggest Tendering Mistakes Contractors Make and How We Help To Avoid Them

Tendering is one of the most important parts of running a construction business, yet it’s also one of the most misunderstood. Many contractors lose jobs not because they lack skill, but because their tender submissions don’t reflect their true value.

At Ashvic Construction, we support contractors and subcontractors with tendering, estimating, and bid preparation. Over time, we’ve identified the most common mistakes that cost contractors work and how to fix them.

1. Submitting Prices Without a Breakdown

Clients want transparency. A single lump-sum price per category raises questions:

  • What’s included?
  • What’s excluded?
  • How was it calculated?

A breakdown builds trust and makes your bid easier to compare. We help identify what drawings and specifications were used to price and in-case there isn’t an enough information, we help produce estimations based on previous experiences and with help of our supply chain to provide costs and descriptions against them for clarity.

We prepare clear, professional breakdowns that help contractors and subcontractors stand out.

2. Missing Key Documents

Many tenders are rejected simply because required documents are certification/accreditation certificates are missing, such as:

  • insurance certificates
  • Constructionline/ CHAS certificates/confirmation letters
  • method statements
  • risk assessments
  • programme of works, breakdown of labour
  • company information

We review Tender documents received and help prepare complete tender packs that meet client requirements and in many cases go above client requirements to help you stand out.

3. Under-pricing to “Win the Job”

This is one of the most damaging mistakes but one of the most used by Contractors and subcontractors, as they look to chase cashflow and keep project teams busy. Under-pricing can be very damaging and leads to:

  • cashflow issues, later down the line,
  • means delays in paying suppliers, subcontractors and operatives,
  • disputes, you end up wasting time in disputes arguing for every 50:50 item and even trying to find angles to argue items which could of easily being excluded or clarified,
  • rushed workmanship means loss of quality in works, especially items behind the scenes as subcontractors relay on no one noticed the work till its too late,
  • reputational damage, clients often wont trust you again for future projects.

Winning a job at a loss is not a win, especially if the client teams do their due diligence in making sure everything is included correctly in contract documents (This is more of reminder for clients).

Ashvic ensures pricing is accurate, competitive, and profitable without the need for stressing on problems which could of easily being avoided.

4. Not Highlighting Experience or Strengths

Clients want to know:

  • what you’ve done before
  • what makes you reliable
  • why you’re the right choice

Many contractors forget to include:

  • case studies
  • photos
  • testimonials
  • relevant experience

We help contractors present themselves professionally so clients can see their value.

5. Poor Communication During the Tender Process

Clients often ask questions during tendering. Slow or unclear responses can cost you the job.

Ashvic supports contractors by managing communication, clarifying requirements, and ensuring deadlines are met.

6. Not Reviewing the Contract Before Pricing

Contract terms affect:

  • risk
  • cost
  • timelines
  • payment schedules
  • cashflow

Pricing without reviewing the contract can lead to losses.

We review contracts for contractors, so they understand what they’re agreeing to before submitting a price, for example understating the importance of contract completion date and seeing how that will be achievable, i.e will their be internal team ready to jump on will their need to be recruitment required or additional external support will be required for short term to get the project up and running.

Final Thoughts

Tendering isn’t just about submitting a number, it’s about presenting your business professionally, pricing and programming accurately to demonstrate reliability.

  • prepare winning tenders
  • price jobs correctly
  • avoid costly mistakes
  • present themselves professionally
  • secure long-term work

With the right support, contractors can win more projects, protect their margins, and grow sustainably.
