Singapore’s adoption of the Peppol network, branded locally as InvoiceNow, is transforming how businesses exchange invoices. This nationwide framework standardizes electronic document exchange, significantly reducing manual errors and speeding up payment cycles. A critical aspect of successful implementation is ensuring your financial systems correctly handle currency codes. For global businesses leveraging Singapore Localization within the Peppol network, currency code setup boils down to adhering strictly to one international standard: ISO 4217 Alpha-3.
New Stuff: – Term Code Master Configuration for E-Invoicing in Singapore Localization Suite
In this blog series, we will see the implementation of Currency Codes for Singapore Peppol-based e-invoicing with Sage Intacct via the InvoiceNow network.
In order to achieve seamless end-to-end InvoiceNow transmission, ensuring full alignment between Sage Intacct’s Currency Codes master and the International currency codes defined in the official ISO 4217 code list is mandatory. To simplify this essential mapping process and prevent manual errors that lead to invoice rejections during Access Point validation, we’ve developed a dedicated Currency Codes Mapping User Interface (UI) within the Sage Intacct InvoiceNow configuration module.
We’ll now cover the configuration workflow and mapping best practices to show how this setup enables Sage Intacct to generate compliant Peppol XMLs for direct transmission via your InvoiceNow Access Point.
Below is the screenshot for Currency Codes UI:

In the screenshot, as shown, the user first needs to select the Currency Code from Sage Intacct under “Currency and Format Setup.” Then, in the “InvoiceNow Currency Code” field, the user must choose the corresponding E-Invoicing Currency Code from the picklist. The picklist is fully compliant with Peppol BIS Billing standards, in accordance with Singapore’s e-invoicing requirements. Entity ID will automatically get populated after User clicks on the save Button.
Accurate Currency Code mapping via Sage Intacct’s dedicated InvoiceNow UI ensures your invoices are 100% compliant with Peppol BIS Billing 3.0 (SG profile), eliminating one of the top causes of Access Point rejections. With this foundation in place, you’re ready for Singapore’s mandatory B2B e-invoicing rollout (2025–2027), faster payments, and zero-touch processing.
