Terms of Service

These terms apply to Zaccount, the cloud accounting software at zaccount.app, including Zac, its AI assistant (together, the Service). The Service is provided by Lydec Services Pte. Ltd. (UEN 202645391N), 60 Paya Lebar Road, #06-28, Paya Lebar Square, Singapore 409051 (Lydec, we). The organisation that subscribes is the Customer, and the people it lets sign in are its users. By using the Service you agree to these terms on the Customer's behalf, and you confirm you are authorised to. If the Customer has a signed agreement with Lydec, that agreement prevails where it differs from these terms.

1. The Service

Zaccount is double-entry accounting software: sales and purchases, banking, multi-currency, GST, reports and, depending on the plan, inventory, projects, maintenance contracts and payroll. What each plan includes is set out in the Customer's order or quotation.

2. Zac, the AI assistant

• Zac answers questions about the Customer's books and prepares work — journals, invoices, bills, quotations, credit notes, payments and more — from instructions and uploaded documents.
• Zac never posts. Everything Zac prepares is a Draft. Nothing reaches the ledger, a bank, a customer or a supplier until a user reviews and confirms it. Zac cannot change settings, the chart of accounts, users or permissions, and works only within the signed-in user's own permissions.
• Zac uses artificial intelligence and can make mistakes — misread a document, pick the wrong account or miss something. The Customer is responsible for checking every Draft before confirming it, and for the records it keeps and the returns it files.
• Zac's explanations of accounting standards, GST, CPF or other rules are general information, not professional accounting, tax or legal advice. Zac is not a public accountant, auditor or tax adviser.
• Each Zac seat includes a fair-use daily allowance, and each company a monthly limit. When a limit is reached, Zac pauses until it resets.

3. Users and accounts

The Customer's Super Admin decides who may sign in and what each user may do. The Customer is responsible for its users, for keeping sign-in details secure, and for telling us promptly of any unauthorised access.

4. Acceptable use

The Customer and its users must not:

• use the Service for anything unlawful, or record fraudulent transactions;
• try to get around security, permissions or Zac's safeguards — including by instructions designed to make Zac act outside them;
• upload malicious files, or disrupt or overload the Service;
• copy, scrape or reverse-engineer the Service.

5. The Customer's data

The Customer owns the data it enters and the files it uploads. It gives Lydec the right to store and process that data only to provide, secure and support the Service. For personal data in the Customer's books, Lydec acts as the Customer's data intermediary under Singapore's Personal Data Protection Act. How we handle data is set out in our Privacy Policy.

6. Fees and payment

• Setup fee: as quoted after a scoping session — 30% on signing, 70% on go-live.
• Subscription: billed monthly in advance, or yearly in advance at the yearly price.
• Payroll add-on: billed monthly in arrears, per employee paid in that month's posted payroll run.
• Prices are in Singapore dollars and exclude GST, which is added where it applies.
• Payment is due within 7 days of the invoice. We send a reminder when an invoice is 7 days overdue. Lydec may charge late interest of 1.5% a month on overdue amounts.
• If an invoice is 30 days overdue, Lydec may, after 7 days' written notice, make the Customer's account read-only — users can still sign in, view and export, but not make changes — until it is paid.

7. Refunds

• Monthly subscriptions: no refund for part of a month.
• Yearly subscriptions: no refund, except a pro-rated refund of unused months if Lydec ends the Service or materially fails to provide it.
• The setup fee is not refundable once work has started.

8. Term and cancellation

• Monthly subscriptions continue until cancelled; a cancellation takes effect at the end of the following billing month.
• Yearly subscriptions renew automatically unless cancelled at least 30 days before renewal.
• Lydec may suspend or end the Service if the Customer seriously breaches these terms and doesn't fix it within 14 days of notice, or immediately where needed to protect the Service or other customers.
• If Lydec decides to stop offering the Service, it will give at least 90 days' notice.

9. When the subscription ends

• Full export: on request within 60 days of the end, Lydec provides a full export of the Customer's data — its records in spreadsheet form, its documents as PDFs, and its uploaded files. During those 60 days the account is read-only.
• Read-only archive (optional): instead, the Customer may keep read-only access for S$15 a month or S$150 a year, for as long as it pays.
• Record keeping is the Customer's duty. Singapore law requires companies to keep their accounting records for five years; the Customer should export or archive accordingly.
• After the export period (or when the archive ends), the Customer's data is deleted. Copies in backups are deleted within a further 90 days.

10. Availability and support

We use reasonable efforts to keep the Service available and secure, but we don't guarantee it will be uninterrupted or error-free. We give at least 48 hours' notice of planned maintenance, carried out outside Singapore business hours where possible, and tell Customers promptly about incidents that affect them. The Service relies on third-party providers (hosting, database, email and AI), listed in our Privacy Policy.

11. Payroll, tax and filings

Zaccount calculates figures such as CPF, SHG and SDL contributions and GST returns from the data the Customer enters. The Customer is responsible for checking them and for what it submits to CPF Board, IRAS and other authorities. Electronic invoicing (InvoiceNow) is sent through third-party access points.

12. Intellectual property

Lydec owns the Service, its software and its content. The Customer receives a right to use the Service during its subscription. Suggestions the Customer gives us may be used to improve the Service.

13. Confidentiality

Each party keeps the other's confidential information confidential and uses it only for these terms, except where disclosure is required by law.

14. Limitation of liability

• Neither party is liable for indirect or consequential loss, or for loss of profit, revenue, goodwill or data, or tax penalties, arising from these terms or the Service.
• Lydec's total liability for all claims is limited to the fees the Customer paid in the 9 months before the event giving rise to the claim.
• Nothing limits liability for fraud, wilful misconduct, death or personal injury caused by negligence, or anything else that cannot be limited by law.

15. Indemnity

The Customer indemnifies Lydec against claims arising from data the Customer or its users put into the Service unlawfully, or from their breach of section 4.

16. Changes to these terms

We may update these terms. We will give at least 30 days' notice of a material change by email or in the Service; continuing to use the Service after that means accepting the change.

17. Governing law

These terms are governed by the laws of Singapore, and the courts of Singapore have exclusive jurisdiction.
