ERP Consultant for Singapore

GST and InvoiceNow in one system

GST in Singapore is administered by the Inland Revenue Authority of Singapore. GST-registered businesses need correct tax invoices, accurate records and periodic returns, all of which depend on every sale and purchase carrying the right tax treatment.

InvoiceNow is Singapore's national e-invoicing network, built on the international Peppol framework. Instead of emailing PDFs, businesses exchange structured invoice data through access points, which reduces re-keying and speeds up processing. IRAS has also been introducing requirements for GST-registered businesses to send invoice data through InvoiceNow, so it is becoming part of GST compliance rather than an optional extra.

In my ERP consulting work, I design tax codes, account structures and invoice data with your tax advisor's input, and I check how each platform connects to InvoiceNow, whether natively or through an access point provider. I do not give tax or legal advice. Because requirements and timelines continue to evolve, I always recommend confirming GST and InvoiceNow features with the software vendor and a Singapore tax advisor before go-live.

Regional HQs, multi-entity groups and multi-currency

Singapore is a common base for regional headquarters, with subsidiaries or branches in markets such as Malaysia, Indonesia, Vietnam, Thailand or the Philippines. Each entity may have its own currency, tax rules and local reporting, yet leadership in Singapore wants one consistent view of the group.

I set up each entity as its own company within the ERP, with SGD as the base currency for the Singapore entity and local currencies where needed elsewhere. I configure intercompany transactions, management fees and transfers so they are recorded on both sides, and build consolidated reports so management does not depend on spreadsheet roll-ups.

Not every platform handles every Southeast Asian country's localization equally well, and some local requirements may be better served by a local accounting tool integrated with the group ERP. I compare these options openly during selection. For trading-heavy groups, my article on ERP for trading companies covers inventory, landed costs and multi-currency pricing in more detail.

Platforms that fit Singapore businesses

For Singapore companies, I screen platforms on GST handling, InvoiceNow connectivity, multi-currency revaluation and, for regional groups, how well each one covers the other countries where you operate. A platform that fits the Singapore entity perfectly but cannot support your Malaysian or Indonesian subsidiaries may not be the right group choice.

• Zoho suits SMEs and services firms that want finance, CRM and inventory in one suite with Singapore GST settings.
• Odoo fits trading and distribution groups with several companies; I check the localization available for each country you operate in.
• ERPNext works for technology-minded businesses that want open-source software and are willing to build or source local features.
• Microsoft Dynamics 365 suits regional headquarters with many entities, heavier consolidation needs or group IT standards built on Microsoft.

Every vendor runs the same scripts: a management fee charged from Singapore to a regional subsidiary, a Peppol invoice sent through InvoiceNow, and a month-end revaluation of foreign-currency balances. I score them on one sheet through my ERP evaluation service, so leadership can compare options on evidence rather than sales presentations.

Integration and data migration in Singapore

Singapore businesses tend to use many digital services, so integration planning matters. Customers pay by PayNow, GIRO or cards through payment gateways, payroll products calculate CPF contributions, eCommerce brands sell on Shopee and Lazada as well as their own store, and trading companies often hold stock with third-party logistics providers whose systems need to exchange orders and stock levels with the ERP.

For each integration I document the system of record, data fields, frequency, owner and failure handling, and test with real sample data before go-live. Marketplace settlements need particular care: fees, refunds and payouts should reconcile to the ledger without manual spreadsheets. Where regional subsidiaries keep a local accounting tool, I design a structured feed into the group ERP for consolidation. My ERP integration service covers the approach.

Many Singapore firms migrate from Xero, QuickBooks or a mix of local packages across the region. I harmonize the chart of accounts and master data across entities, decide how much history each company brings, and reconcile opening balances, GST accounts and intercompany positions at cutover. The method is set out on my ERP data migration page. All work is delivered remotely; see my Singapore page for more on how I work with businesses there.

Working remotely with Singapore businesses

I work remotely with businesses in Singapore. Remote delivery works well for ERP projects when there is a clear scope, a shared plan, regular working sessions and decisions recorded in writing.

Singapore and India have a small time difference, so workshops, reviews and training fit comfortably within your normal working day. Asynchronous updates, recorded walkthroughs and a shared project tracker keep regional teams aligned between calls, which is especially useful when users sit in several countries.

Common industries I work with in the region include trading and distribution, logistics, professional services and technology businesses. Many also need connected systems across ERP, CRM, e-commerce and banking, which I can cover through system integration.

Before recommending any technology, I take time to understand how your business actually runs: who approves what, where information gets stuck and which reports leadership relies on. If you are planning a new system, get in touch to talk through your requirements.
