Terms of Service

1. About these terms

These terms are an agreement between you and Keisan Systems Pty Ltd (ACN 703 947 853) ("Keisan", "we", "us") for using Keisan, our online accounting and payroll software (the "Service"). "You" means the person signing up and the business they use Keisan for. If you sign up for a business, you confirm you're allowed to agree to these terms for it.

Our Privacy Policy explains how we handle personal information, and forms part of these terms.

2. Free trial

You can use Keisan free for 30 days, without giving payment details. To keep using it after the trial, add your payment details before the trial ends. If you don't, we may limit your account to read-only access or suspend it, and your data is kept as described in section 9.

3. Fees and payment

• Fees are the prices shown on our website when you subscribe, in Australian dollars, including GST where it applies.
• Subscriptions are charged monthly in advance, from the end of your trial, and renew each month until you cancel.
• You can cancel at any time. Cancelling takes effect at the end of the month you've paid for, and you can use the Service until then.
• We don't refund part months, except where the law requires it (see section 10).
• We'll tell you at least 30 days before a price change takes effect. If you don't want to pay the new price, you can cancel before then.
• If a payment fails, we'll let you know. If it's still unpaid 14 days later, we may suspend your account until it's paid.

4. Your account

• Give us accurate details, and keep your email address up to date: it's how we contact you.
• Keep your password secret, and tell us straight away if you think someone else has used your account.
• You're responsible for what happens in your account, including what people you invite (such as an accountant or bookkeeper) do with the access you give them. You can remove their access at any time.

5. Your responsibilities for your records and lodgements

Keisan is a tool to help you keep your books and pay your employees. It isn't tax, accounting, legal or financial advice, and doesn't replace a registered tax or BAS agent. You remain responsible for:

• the accuracy of what you enter, and checking the figures Keisan calculates (such as pay, tax withheld, super and GST) before relying on them;
• your business activity statements, Single Touch Payroll reports, super payments and other lodgements and payments, and lodging and paying them on time;
• keeping the records the law requires you to keep, for as long as it requires (generally $7 years for tax, company and employee records); and
• having the right to give us the information you enter about other people, such as your employees, customers and suppliers, and telling them about it where the law requires.

Where Keisan sends information to the Australian Taxation Office or anyone else for you (such as Single Touch Payroll reports), you authorise us and our service providers to send it on your behalf.

6. Acceptable use

You mustn't:

• use the Service for anything unlawful, fraudulent or misleading;
• try to get into accounts or data that aren't yours, or to test, probe or get around our security;
• interfere with the Service or put an unreasonable load on it, including with automated tools; or
• copy, resell or reverse-engineer the Service, except where the law allows it.

7. Your data

The data you put into Keisan is yours. You give us permission to store, process and copy it only to provide, secure and support the Service, to comply with the law, and as our Privacy Policy describes. We don't sell your data.

We take regular backups, but we recommend you keep your own copies of important records, such as reports and statements.

8. The Service

We work to keep Keisan available and accurate, but we can't promise it will always be available or free of errors. We may need to take it offline for maintenance, which we'll try to do outside business hours. We improve and change the Service over time; if we remove a feature you rely on, we'll tell you first where we reasonably can.

9. Ending your account

You can close your account at any time by contacting us. We may suspend or close your account if you seriously or repeatedly breach these terms, don't pay fees when due (see section 3), or if we stop providing the Service, in which case we'll give you at least 60 days' notice and refund any fees paid for the time after it ends.

After your account closes, or your trial ends without a subscription, we keep your data for 7 years, so you can come back to it, or ask us for a copy of it, for as long as you may need your records. After that we delete it. You can ask us to delete it sooner, except where the law requires us to keep it.

10. Our liability

Nothing in these terms excludes, restricts or changes any right or remedy you have under the Australian Consumer Law or another law that can't be excluded. Where the law lets us limit our liability for failing to meet a guarantee, our liability is limited, at our option, to supplying the Service again or paying the cost of having it supplied again.

Otherwise, to the extent the law allows:

• we're not liable for indirect or consequential loss, or for loss of profits, revenue, data or opportunity, or for penalties, interest or charges imposed on you by the Australian Taxation Office or anyone else;
• our total liability to you for all claims arising out of or in connection with the Service is limited to the greater of the fees you paid us in the 12 months before the claim arose and $100; and
• our liability is reduced to the extent you contributed to the loss, including by not checking figures or lodgements as section 5 describes.

These limits don't apply to loss caused by our fraud or wilful misconduct.

11. Changes to these terms

We may update these terms. We'll tell you by email or in Keisan at least 30 days before a change that disadvantages you takes effect. If you don't agree with it, you can cancel before then and we'll refund any fees you've paid for the time after it takes effect. Continuing to use the Service after a change takes effect means you accept it.

12. General

• These terms are governed by the laws of Victoria, Australia, and you and we submit to the non-exclusive jurisdiction of its courts and the courts that can hear appeals from them.
• If part of these terms is unenforceable, it's read down or severed, and the rest continues to apply.
• We may transfer our rights and obligations under these terms to someone who takes over the Service, on notice to you.
• If we don't enforce a right straight away, we don't give it up.
