IRAS-compliant tax invoices with your GST number, GST at the current 9%, structured data for InvoiceNow, and fast payment options. All on one flat plan.
Singapore invoicing means IRAS-compliant tax invoices that carry your GST registration number and the current 9% GST, and, with InvoiceNow rolling out, keeping your invoices as clean structured data. Billbooks handles the compliance so you get paid without the paperwork.
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.

Billbooks applies the current 9% GST and includes the required fields on every invoice.
