Terms of service

Last updated 10 November 2026

These terms are an agreement between you (and the business you use BooksGURU for) and Aster IT Ltd, company number 17491204 ("we", "us"), which runs BooksGURU at booksguru.net. By creating an account or using BooksGURU you agree to them.

The service

BooksGURU lets you keep your business accounts online: invoices, quotes, bills, payments, VAT, reports and the people behind your business. We may improve and change the service over time, and will give reasonable notice before removing a feature you pay for.

Early access

While BooksGURU is in early access it is free to use. Some features are still being built and things may change. We will tell you before any charges start, and you can choose whether to carry on.

Your account

Keep your sign in details safe and tell us if you think someone else has used them.
You are responsible for what happens under your account, including the people you invite to it and the level of access you give them.
You must be at least 18 and able to agree to these terms for your business.

Your records and your tax

Your records belong to you. You give us permission to store and process them only so we can run the service.

BooksGURU is a tool for keeping your books. It is not tax, legal or accounting advice. You are responsible for the accuracy of what you enter, for checking figures before you file them with HMRC or Companies House, and for meeting your own deadlines. If you are unsure, ask an accountant.

You must not use BooksGURU for anything unlawful, including fraud or hiding income, to break anyone else's rights, or to try to break or overload the service. We may suspend an account that does.

Connected services

If you connect Stripe, GoCardless or other services, your use of them stays under their own terms. Payments your customers make go to your account with that provider, not to us.

Availability and liability

We work hard to keep BooksGURU running and your records safe, but we can't promise the service will never be interrupted. Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or anything else the law does not allow us to limit. Otherwise, we are not liable for indirect or consequential losses, lost profits, penalties or interest charged by HMRC or others, or lost data, and our total liability in any 12 months is limited to what you paid us in that period, or £100 if more.

Ending the agreement

You can close your account at any time by contacting us. Before you do, ask us for a copy of your records if you need one. We may suspend or close an account that seriously or repeatedly breaks these terms. After closing, we delete your records as described in our privacy policy.

Changes and law

We may update these terms and will email account owners about significant changes before they take effect. These terms are governed by the law of England and Wales, and the courts of England and Wales deal with any dispute.
