Billing Overview

From 1 July 2025, SMSes sent out via Postman will be charged to agencies. Please read this page to understand about the billing process along with the prerequisites for billing.

Cost of messages

Only messages sent out from Postman's production environment will be charged (messages to members-of-public must be sent from the production environment).

Messages will be charged based on the recipient's number. All charges are subject to GST which will be charged in the final invoice. The cost for recipients are as follows:

• Local numbers (+65) - $0.046 SGD per message segment

• Foreign numbers (all other numbers) - $0.23 SGD per message segment

GST will be included in the final invoice at the prevailing GST rate. The Postman team previously communicated to several agencies that no GST would be included. We regret this error and apologise for any inconvenience caused. Please reach out to the BTN Finance team via email should you have any questions.

Also note that prices above are based on message segments. Each message to recipients can contain multiple message segments based on its length. Refer to the message segment calculator page below for more details on how message segments are calculated.

Messages which have failed to be delivered due to invalid numbers will also be charged. Refer to the detailed charges and pricing page below for more details.

Billing Process

Billing will be based on the campaign creator's email domain.

• e.g. if a campaign is created by [email protected], SMS charges will be billed to CPF directly via an invoice from GovTech.

Please ensure that all campaigns have the correct campaign creator set as billing charges will not be reversed.

PICs and campaign creators can see monthly billing reports in the billing dashboard (invoices are only sent out yearly). A yearly report will also be made available for download in mid-March.

If there are any discrepancies for the monthly reports, a dispute can be raised with the Postman team via email within 30 days from the posted date.

Billing will follow a post-paid model, where agencies will be invoiced annually in March for their previous year's usage. A breakdown of the billing cycles are shown below.

Usage Period	Invoice Date
First year 1 July 2025 - 31 January 2026	GovTech invoice will be sent to agencies in mid-March 2026
Second year 1 February 2026 - 31 January 2027	GovTech invoice will be sent to agencies in mid-March 2027
Subsequent years (same cycle as second year)	(GovTech invoice will be sent to agencies in mid-March similar to the second year)

Agency PICs will need to submit their agency's payment information to OGP via this form before November 2025.
