Why Singapore bookkeepers choose ExpenseFlow
Singapore is small geographically but disproportionately complex in its bookkeeping work. The market is dominated by SMBs with regional operations, multi-entity holding structures, and a constant stream of cross-border invoices that ordinary expense apps do not handle correctly. Bookkeepers here are juggling IRAS GST compliance, MAS-regulated transactions, ACRA filing deadlines, and clients who routinely operate in three currencies before lunch. ExpenseFlow is built for that density.
Three pieces of friction define the Singapore workflow. First, the 9% GST rate (raised from 7% in two steps over 2023 and 2024) means rate transitions still show up in legacy receipts. Second, reverse charge and OVR rules for imported services mean a Singapore SMB receiving a SaaS invoice from a US vendor has a distinct GST treatment depending on whether the vendor is OVR-registered. Third, multi-entity portfolios are unusually common: a single client might be a holding company plus three operating subsidiaries plus a regional services entity, each with its own GST registration and accounting file. ExpenseFlow’s AI applies the correct GST treatment per receipt, and the bookkeeper portal makes entity switching one click rather than a re-login.
For practices serving SMB and multinational regional clients, that means less time spent re-keying tax codes and more time on advisory work.
IRAS compliance built in
IRAS’s record-keeping rules are codified in the IRAS GST General Guide for Businesses and the Income Tax Act, with e-Tax Guides covering electronic records, reverse charge, and OVR. ExpenseFlow’s defaults align with all of them.
- GST handling at the current 9% rate, with automatic application of the historical 7% and 8% rates for receipts in those date ranges, plus zero-rated, exempt, and out-of-scope treatments
- Reverse charge and OVR tagging for imported services and overseas-vendor digital subscriptions, so GST-registered businesses post the correct treatment to Xero or QuickBooks Online
- Audit trail preserved: immutable image, hash, timestamp, and link to the resulting accounting entry, held for the IRAS five-year retention period
- Tax-invoice-compliant fields extracted (supplier name, GST registration number, invoice date, total, and GST component) and stored as structured data
- Direct sync to Xero and QuickBooks Online preserves the GST code, tracking categories, and supplier records intact
For clients on the Major Exporter Scheme, the Tourist Refund Scheme, or other industry-specific GST regimes, the captured data is structured enough to support the scheme’s reporting without manual rework.
Integrations for Singapore accounting workflows
Singapore is heavily Xero-led, with a meaningful QuickBooks slice in the SMB segment. ExpenseFlow ships with both today:
Xero. The dominant SMB and bookkeeping-practice platform in Singapore. Bills, expenses, and supplier credits sync two-way with the correct Singapore GST codes, tracking categories, and contact records preserved. Multi-currency receipts post at the correct exchange rate.
QuickBooks Online (Singapore). Used by a meaningful share of SMBs and franchise systems. Full Singapore GST mapping, including reverse charge and OVR treatments.
Multi-entity groups are first-class in the portal: each entity has its own workspace, integration, and isolated audit trail, and the bookkeeper can move between them without re-authenticating. For regional groups with subsidiaries in Malaysia, Indonesia, or Hong Kong, the same portal hosts those entities, though only Singapore-specific tax handling ships in this release. Other platforms can be requested directly; the founder will follow up directly to talk through your stack.
Pricing for Singapore practices
ExpenseFlow’s subscription is billed in USD across every jurisdiction. One rate card, no FX surprises at renewal. Receipt capture, Singapore GST coding, and sync to Xero or QuickBooks Online still run in SGD for your Singapore clients; only the SaaS subscription itself is USD. The model scales by the number of client companies under management, which is useful for practices serving multi-entity groups where each sister entity needs separate handling.
Per-company pricing covers receipt capture, AI categorisation, Singapore GST coding, sync to Xero or QuickBooks Online, and bookkeeper-side review tooling. Founding-customer pricing currently locks in a 25% discount for the life of the account. Full pricing tiers are on the bookkeeper pricing page.
