Run your Singapore company on the InvoiceNow standard — from ACRA incorporation to ASEAN expansion.
IRAS has made InvoiceNow the national e-invoicing backbone: every GST-registered business must exchange invoices over the Peppol network in UBL format. Layer in a 9 % GST regime, CPF as the statutory payroll framework, PayNow as the dominant payment rail, and ACRA as the company registry — and you need software that treats these rules as first principles, not afterthoughts. The 4b2b suite covers the entire company lifecycle for Singapore.

Singapore did not merely adopt Peppol — it built InvoiceNow around it, positioning IRAS as the de facto clearinghouse for digital business transactions. Every invoice, quarterly GST F5 return and payroll run operates inside this framework. The 4b2b suite treats IRAS and InvoiceNow as the primary source of truth, not a compliance bolt-on.
Company Formation & Registration
Incorporating in Singapore involves more than filing an ACRA form. From the day the UEN is issued, the company enters the InvoiceNow Peppol ecosystem, the GST regime and the CPF payroll framework. These six topics walk through each step — and how the 4b2b suite slots in at each one.
Operations — GST 9 %, InvoiceNow, CPF Payroll, PayNow
The operational rhythm of a Singapore company: a 9 % GST regime with quarterly F5 returns, InvoiceNow Peppol transmission required for every taxable invoice, CPF contributions due monthly for every locally employed staff member, and PayNow as the dominant payment rail. These six topics cover each obligation in detail.
Cross-border — ASEAN, Exports & Regional HQ
Singapore sits at the intersection of the global Peppol network and the ASEAN economic bloc — a founding ASEAN member with over 100 double taxation agreements, a zero-rated GST regime for exports, and an internationally recognised legal system for holding regional IP and treasury functions. These six topics address each cross-border dimension in detail.

Partner programme — Singapore
Accountants, corporate secretaries and IT consultants who refer the ecosystem earn a recurring commission for every active client mandate — not a one-off referral fee. The more modules a client uses, the higher the combined commission.
Recurring commission on every client mandate you refer and retain — GST F5, payroll, InvoiceNow and bookkeeping all count.
Earned on referrals arising from ACRA incorporation, UEN setup and CorpPass compliance work you carry out for clients.
Tiered upward when you integrate multiple modules — invoicing, ERP, HR and notifications — for a single client project.
