What this tool does

This generator preconfigures Singapore conventions: the SGD currency, the GST label, DD/MM/YYYY dates and A4 paper size. You enter your details and line items; it calculates subtotal, discounts, tax and the grand total, then renders a print-ready PDF entirely in your browser.

Currency: SGD ($)

Amounts use en-SG grouping and decimal rules and are rounded to 2 decimal places, as used by SGD.

Tax terminology: GST

Invoices are labelled with the terminology Singapore businesses expect. Presets are provided as a starting point and are not tax advice.

Singapore consumer prices normally include GST at 9%.

Invoice numbering

Default numbering pattern: INV-2026-0042. Sequential numbering with the UEN visible is standard practice.

Payment practice

Common payment terms used in Singapore: On receipt, 14 days, 30 days, 60 days. Always state a due date, and ask customers to quote the invoice number as the payment reference.

What a Singapore invoice usually includes

  • Business name and UEN
  • Customer details for B2B
  • Invoice number and date
  • Description and amount
  • GST breakdown and total in SGD

Designed for common invoicing practices in Singapore. Requirements may vary by business, transaction type and jurisdiction. Please verify local requirements with a qualified professional.

Invoicing notes for Singapore

Practical points to check before you send the invoice.

UEN identifies the business

Your Unique Entity Number belongs on the invoice so corporate customers can verify the supplier.

Output tax detail

GST-registered sellers must show the GST amount charged per rate for the customer to claim it.

Regional invoices

Cross-border supplies are often zero-rated — state clearly when GST is not charged and why.
