Signing a document electronically

What you are agreeing to when you tick the consent box and sign. Plain language, and short on purpose. Last updated August 2026.

1. Who is who

The document you have been asked to sign comes from your builder — the business named in the email that sent you here. They wrote it, they decide what is in it, and any question about the contents is one for them.

BuildRocket is the software they used to send it. It is operated by C3 Builder Pty Ltd. We provide the signing tool and keep the record of what happened; we are not a party to your contract and we do not give legal advice about it.

2. You do not have to sign electronically

Signing on screen is offered because it is quicker, not because it is required. If you would rather sign a printed copy, ask your builder for one — they can print the same document and take your signature on paper. Nothing on this page stops you doing that, and there is no penalty for asking.

You should only sign electronically if you are happy to, and if you can read the document on the device in front of you.

3. What your consent means

Before you can submit a signature, you tick a box saying you consent to signing electronically and understand that your electronic signature has the same legal effect as a signature in pen.

That tick applies to the document you are signing at the time. It is recorded with the moment you gave it, and it is stored alongside the signature itself, so the record shows that your consent existed when you signed.

4. What is recorded when you sign

Every signature is stored with an audit record. It contains:

• the name you sign under, and your email address from the invitation;
• the signature you draw or type, as an image;
• the date and time you submitted it;
• the IP address and browser your device reported;
• the fact that you consented, and when;
• a fingerprint of the exact document file you signed, so it can be shown later that the document has not been altered;
• which pages you initialled or acknowledged, and any checklist answers you gave.

Your approximate location is optional and off unless you turn it on. There is a separate tick for it. Leave it alone and no location is recorded.

This record is kept so that the signature can be relied on later. It is visible to your builder, and it is attached to the finished document as a Certificate of Signature.

5. Getting your copy

Once everybody has signed, BuildRocket produces the final signed PDF with every signature and the Certificate of Signature in it. Your builder sends that copy to you — it is not emailed automatically. If it has not arrived, ask them for it; they can send it again at any time.

Keep your own copy somewhere safe. We would rather you had one than relied on us holding it for you.

6. Changing your mind

Before you submit, you can simply close the page. Nothing is recorded until you press submit, and an unsigned invitation expires on its own.

After you have signed, the signature stands. Withdrawing consent to electronic signing does not undo a signature you have already given, any more than changing your mind would unsign a paper contract. If you believe you signed something in error, that is a matter to raise with your builder, and it is a question about your contract rather than about this software.

7. How long the record is kept

The signed document and its audit record live in your builder's BuildRocket account and are kept for as long as that account holds the job. Nothing here deletes them on a timer.

Because the record sits in your builder's account rather than yours, a request to remove it goes to them first. If a BuildRocket account is deleted, the data tied to it is permanently removed — we action deletion requests within 30 days, and database backups containing the data roll over within 7 days. That is set out in full on our account deletion page.

8. What you need to sign

A current web browser on a phone, tablet or computer, an internet connection, and the ability to open a PDF. Nothing to install and no account to create. If you cannot read the document properly on your device, stop and ask for a copy you can read — signing something you could not see is not what any of this is for.

9. Questions

About the document — what it says, what it commits you to, when it starts — ask the builder who sent it. They are the other party to it.

About BuildRocket itself — this page, the signing tool, or the record we hold — email admin@buildrocket.ai.

These terms may change. The version that applies to your signature is the one published when you signed, and the audit record fixes that moment.

This page explains how the signing tool works. It is not legal advice, and it does not change the terms of the contract you are signing.
