Free Inventory Software Singapore SME — GST F5, AI | HelloBooks Free inventory management for Singapore SMEs — items, variants, BOM, stock ledger, FIFO/weighted-average valuation, 9% GST rates on stock and purchase lines, AI bookkeeping, and IRAS GST F5 return preparation. IRAS e-filing on the roadmap.
HelloBooks Inventory is the free inventory management software for Singapore SMEs. Items, variants, bill of materials, stock adjustments, transfers and movements all post in real time to inventory valuation and the right account inside the same ledger that runs your invoices and supplier bills, with 9% GST rates applied across stock and purchase lines. The free plan covers the full stock surface; the S$13/month Pro tier adds AI bookkeeping and revenue recognition tied to stock transfers. Guided migration from Xero SG, Financio, Zoho Books SG or MYOB brings the entire stock ledger across, not just opening balances. IRAS GST F5 return preparation is built in; IRAS e-filing, CPF payroll and ACRA filings are on our roadmap.
Singapore GST rates are applied across your stock and sales: 9% standard-rated, zero-rated exports, and exempt supplies (financial services, residential property). AI demand forecasting uses 12-month sales history (factoring SG seasonality — Chinese New Year, Hari Raya, National Day, year-end shopping) to surface reorder points, low-stock alerts and stale-stock provisions before they hit the P&L. The Cleanup Dashboard catches missing commodity codes, broken UOM conversions and stuck stock adjustments at the source. IRAS GST F5 return preparation is built in; Major Exporter Scheme (MES) treatment and direct IRAS e-filing are on our roadmap.
What makes HelloBooks Inventory different from Singapore-focused inventory tools is the depth on every adjacent surface: vendor scorecards, purchase requests and POs that flow into Warehouse Receiving (GRN) with automatic GST treatment, BOMs that roll into Manufacturing work orders for Singapore discrete + process manufacturing, and Singapore banking feeds closing the loop on every supplier payment. Stock Ledger, Inventory Valuation (FIFO + weighted-average), Movement Log, Reorder Planning and Profitability Analysis ship in the same dashboard.
