GST at 9%, done right
Billbooks applies the current 9% GST and shows it as a separate amount, so invoices are correct after the 2024 rate change.
IRAS-compliant tax invoices
The words "tax invoice", your GST number, and the required fields appear automatically, with a simplified invoice for totals up to SGD 1,000.
Structured invoice data
Your invoices are stored as clean, structured data, a useful foundation as Singapore rolls out its InvoiceNow e-invoicing network.
GST in Singapore is 9%, raised from 8% on 1 January 2024. You must register for GST once your annual taxable turnover exceeds SGD 1 million, and voluntary registration is available below that. A tax invoice must show the words “tax invoice”, your GST registration number, and the GST as a separate amount, and be issued within 30 days of the supply. A simplified tax invoice is allowed for totals up to SGD 1,000. Singapore is also rolling out InvoiceNow, its Peppol-based e-invoicing network, in phases. Billbooks applies the current 9% GST and includes the required fields on every invoice.
IRAS requires a tax invoice to carry these details. Billbooks includes them on every invoice.
Unlimited invoices on a simple, flat plan, with a 30-day free trial.
A plan built for high-volume transactions or business models that do not fit the mold.
