Can I book an estimate without subscribing to your estimating software?

Yes absolutely, booking in an estimate to be priced up does not require a live subscription to our software. You will still receive full access to our software for the job that we estimate for you, allowing you to amend/alter any of the rates you need to and create your own amendments, should the project scope change.

How much does it cost?

Ballpark costs can be found on our pricing page. However, for a more accurate quote, please use our Quick Quote Tool.

What happens if I need the estimate amending?

We offer an estimate amending service free of charge. If there is anything you need amending or updating, just let us know and we will take care of that for you.

If your amendment is due to a change of design, that materially changes the scope of the project, a small additional charge may be incurred, but we will discuss this with you before proceeding.

Do you offer support?

Yes we do, if, at any stage, you need to discuss the project with us or need help setting up your admin controls to your rates, feel free to contact us here.
