Singapore is one of Asia's leading bases for SaaS companies serving enterprise customers globally. International B2B services exported from Singapore are zero-rated for GST — but correct invoice documentation, Peppol delivery to the customer's access point where available, and reverse-charge analysis for overseas VAT jurisdictions are all required to avoid compliance gaps across multiple markets.
SaaS invoices to overseas B2B customers are incorrectly issued with 9 % GST because the billing system lacks a country-based zero-rating rule — generating refund requests from customers and IRAS queries on every F5 reconciliation.
Automatic zero-rating for qualifying international B2B services based on customer country and supply classification, with clean InvoiceNow output and digital evidence of the customer's overseas location.
Multi-currency SaaS subscriptions are invoiced in USD or EUR but booked in SGD using stale or manually-entered FX rates, distorting the P&L and creating F5 reconciliation problems.
Multi-currency invoice engine with daily IRAS-accepted FX rates applied at the time of issue, with automatic SGD conversion and a separate FX gain/loss ledger for accurate management accounts.
Zero-rated exports, correct FX rates, Peppol delivery — globally consistent.
