Grow Your Business

When you don’t have to worry about your costing process, you can focus on what really matters – growing your business and making your clients happy.

We do costing differently and that means you won’t blow the budget

Are you at risk of underquoting jobs?
Underquoting in the building industry is a common issue. The leading reason for this is lack of accuracy in cost budget planning.

Newin does costing differently!

We create project costings based on current market prices and rates and account for every detail. Complete breakdowns are provided to ensure full transparency.

We believe that detailed accurate budgets are the only way to ensure you maintain complete control over your projects.

Are you looking for cost-effective expertise to better manage projects and without hiring staff?
As a builder, taking time out to manage projects, subcontractors, and cost budgets may not be the best use of your time, and the expense of hiring more staff may not be a viable investment for your business.

We offer builders a cost-effective outsourcing solution, where we become an extension of your team, bringing you cost and construction expertise.

We are serious contract administration experts, so you can feel secure that your project will be managed efficiently, will complete on time, and will stay within budget.

Are you struggling to manage your projects on time and to budget?
At Newin, we know that accurate, detailed, and complete budgets covering every stage and aspect of the project is the only way to ensure you don’t blow the budget and can manage client expectations.

For your peace of mind, Newin is also able to provide ongoing support to the project team and ensure they are fully equipped to manage and control project and trade costs at all stages.

Don’t let bad quoting destroy your business
Providing quotes which do not adequately cover the real cost of a job can ruin your reputation or put you out of business.

A key aspect of winning more building jobs and maintaining your excellent reputation is to ensure you don’t blow your budget or that of the client.

And this all starts with the accuracy of your quotes.

With Newin as your quote costing partner, and using our specialised system, you’ll be able to significantly reduce the error rates of your quotes.
