Online Invoice Generator Singapore Free (GST)

UEN + 9% GST in Singapore dollars

GST-registered businesses show supplier identity, UEN or GST registration number, invoice number and date, customer, description, GST amount, and SGD total. Enter UEN in the supplier tax field; keep 9% when the supply is standard-rated.

/sg is SGD + IRAS GST. If you are not GST-registered, start from no-GST — a cosmetic 9% line that implies registration creates more risk than leaving tax off.

PayNow proxy plus FAST transfer

Clients commonly pay via PayNow (NRIC/UEN or mobile) or FAST/GIRO via DBS, OCBC, UOB, Standard Chartered, HSBC Singapore, Maybank Singapore, Bank of China Singapore, Citibank Singapore, Trust Bank, GXS Bank, MariBank, ANZ Singapore, Singtel Dash, RHB Singapore, CIMB Singapore or peer banks. Put your PayNow proxy and bank account on the invoice; require the invoice number in the transfer reference.

Keep SGD as the default for domestic work. Change currency deliberately for regional clients. Net 14 / Net 30 in the date style your client already uses.

Offer under /sg → tax invoice after agreement

Use an offer for proposals, then convert agreed scope into a tax invoice under /sg. Keep proposal and invoice numbers on separate series.

Leave tax off the offer if GST applies only when you invoice; add 9% after registration and supply type are clear.

IRAS filing stays on mytax Portal
