The problems we solve
You're GST-registered and your current software requires a paid add-on or manual workarounds to handle GST properly.
Singapore GST at 9% is built into every Nastrum Books plan from day one. No add-ons, no workarounds.
You invoice clients across Asia in USD, HKD, MYR, but your books need to be in SGD.
Multi-currency is fully built in. Invoice in any currency, reports always reflect SGD equivalents at locked rates.
Your tax invoices don't show your GST registration number and the tax breakdown IRAS requires.
Nastrum Books tax invoices include your UEN, GST registration number, and itemised tax on every PDF.
You run multiple entities in Singapore and have to log in to separate tools for each one.
Manage all your Singapore businesses from one login. Switch between companies instantly without logging out.
Preparing your GST F5 return means pulling figures from multiple exports and calculating manually.
