Check your deadline
When is InvoiceNow mandatory for you?
Two answers. Ten seconds. Your date.
Indicative, based on IRAS' published wave schedule. The letter IRAS sends your business is authoritative — we verify it during the free check.
Built for the Peppol network
Watch an invoice travel the network
No PDFs, no re-typing. Your invoice leaves MUST as structured data, reaches your customer's software in seconds — and a copy reports itself to IRAS. That is the whole GST InvoiceNow Requirement, handled.
Built for Singapore's rails
Compliance is wired in, not bolted on
Live and compliant in four steps
A fixed onboarding path, not an open-ended IT project.
1 ·Readiness check
A free 15-minute call: your mandate date, current software, and grant eligibility.
2 ·Your quotation
We give you a formal quotation and the solution details your application needs. You apply yourself — grant rules require the applicant to submit, and we never ask for your Corppass.
3 ·Setup & migration
Chart of accounts, customers, products and open balances migrated. Peppol registration done for you.
4 ·Go live & support
Personalised training for your team, then local support on WhatsApp and email.
The same four problems, different words
Wherever people work in shifts, across sites, or on the move, the admin underneath looks the same. Hover a sector to see what it looks like there.
Construction
Site clock-in across projects, foreign worker levies computed from real attendance, and certifications that expire before anyone notices.
Logistics
Driver hours, mileage from real routes, multi-depot rosters and subcontractor cost in one place.
F&B and retail
Split shifts across outlets, part-timers on different rates, and hourly cost per outlet before the month closes.
Field service
Crews deployed to client sites, overtime approved before it happens, labour cost tracked per project.
Manufacturing
Rotating shift patterns that generate themselves, shift allowances applied automatically, headcount planned against production.
Professional services
Billable time, expense claims with receipts read by AI, and GST invoices that go out on the InvoiceNow network.
Rate card
Every line priced separately
Software is licensed per year. Implementation and training are professional services, charged by the day. We are updating our published rates, so each line is quoted individually right now — you still see what every part costs before you commit to any of it, and your invoice reads exactly like this page.
| Item | Unit | Price |
|---|---|---|
| Core system with InvoiceNowIncludes 1 named user | per year | On request |
| Additional users, 2 to 10 | per user / year | On request |
| Additional users, 11 and above | per user / year | On request |
| Professional services | ||
| Implementation, configuration and data migrationTypically 3–5 days for an SME | per day | On request |
| TrainingTypically 1–2 days | per day | On request |
Quoted in Singapore dollars. Licence fees run 12 months from your go-live date. Professional services are quoted as a fixed number of days before work starts, so the first invoice holds no surprises.

Our ecosystem
Our engineering team works across the stack — cloud and data platforms, mobile, web and AI. We pick what fits the problem instead of forcing every problem through one tool.
Your wave is coming. Your grants won't wait.
A 15-minute call tells you your mandatory date, what the Government will pay for, and what it takes to get compliant — no obligation.
