InvoiceNow Singapore: Get Your Invoicing and ERP Ready for E-Invoicing
InvoiceNow Singapore adoption is moving from optional to expected: IRAS has begun phasing in GST InvoiceNow requirements, starting with new voluntary GST registrants, and has announced a progressive extension to all GST-registered businesses. Digital 9 Labs builds InvoiceNow-ready invoicing and ERP workflows so your billing can send structured e-invoices through the Peppol network via accredited Access Point providers.
Custom enterprise resource planning (ERP) software, built for Singapore SMEs. From $3.5k onwards.
Where Singapore SMEs feel stuck
Most off-the-shelf ERP software is built for someone else's workflow. We design around yours.
PDF invoices are not e-invoices
Emailing a PDF is not InvoiceNow. The network transmits structured invoice data machine-to-machine, and most homegrown invoicing tools cannot produce it.
Unclear what the GST timeline means for you
IRAS has begun phasing in GST InvoiceNow requirements, starting with new voluntary GST registrants, and has announced an extension to all GST-registered businesses in stages. Many owners are unsure when their business is affected.
Legacy invoicing cannot map to Peppol
Older systems store line items, GST treatment, and party details in formats that do not translate cleanly into the structured invoice format Peppol requires.
GST categories are inconsistent
Standard-rated, zero-rated, and exempt supplies are labelled differently across quotes, invoices, and accounting exports, which breaks validation.
Double entry between systems
Staff key the same invoice into the operations system, the accounting software, and sometimes a customer portal, so errors and delays multiply.
No status visibility after sending
Once an invoice leaves your system, nobody knows if it was delivered, rejected, or stuck, so finance chases payments blind.
What we build into your ERP
Pick the modules that match how your team actually works. Everything connects to a single source of truth.
Structured E-Invoice Generation
Generate invoices as structured data aligned to the Peppol format used by InvoiceNow, not just a PDF layout.
Pre-send Validation
Validate mandatory fields, GST categories, UEN and party details, and totals before an invoice is transmitted, so rejections are caught early.
Access Point Transmission
Connect your invoicing to an IMDA-accredited Peppol Access Point provider, which handles delivery over the InvoiceNow network.
GST Category Mapping
Map your products and services to the correct GST treatment once, so every invoice carries consistent, compliant tax data.
Invoice Status Tracking
Track sent, delivered, and rejected statuses inside your own system instead of guessing after the invoice leaves.
PDF Fallback for Non-Peppol Customers
Customers not yet on the network still receive branded PDF invoices from the same workflow, with no double entry.
Quote-to-Invoice Flow
Accepted quotes, delivery orders, and progress claims flow into invoices, so billing data is entered once and reused.
Invoice Register and Audit Trail
Every invoice, revision, credit note, and transmission attempt is logged for GST reporting and internal control.
ERP and Accounting Integration
Connect e-invoicing to your custom ERP or push records to your existing accounting software instead of retyping.
How we deliver
Invoicing and GST review
We map your current invoicing flow, GST treatment, customer types, and existing software to see what InvoiceNow readiness requires.
Build the e-invoicing workflow
We build or adapt your invoicing so it produces validated, structured e-invoices and connects to an accredited Access Point provider for transmission.
Connect operations and finance
Quotes, orders, and delivery records flow into invoicing, and invoice statuses flow back into your finance dashboard.
InvoiceNow-Ready Workflow vs Manual Invoicing
Manual PDF invoicing
- Invoices are typed or copied into templates, then emailed as PDFs.
- GST fields and customer details are re-entered by hand each time.
- No structured data, so customers and IRAS-facing systems cannot process invoices automatically.
- No delivery status, so finance follows up by asking the customer.
Digital 9 Labs InvoiceNow-ready workflow
- Invoices are generated as structured e-invoices from your existing quote and order data.
- Validation catches missing fields and GST errors before sending.
- Transmission goes through an accredited Peppol Access Point to customers on the network.
- Statuses, registers, and audit trails live inside your own system.
What InvoiceNow Actually Is
A nationwide e-invoicing network
InvoiceNow is Singapore's national e-invoicing initiative, built on the international Peppol framework, that lets businesses send invoices as structured data directly between finance systems.
Built on Peppol
Peppol is an open standard for exchanging business documents. Your software produces the invoice in the required format, and accredited Access Point providers deliver it across the network.
Why IRAS cares
IRAS has begun phasing in the use of InvoiceNow for GST-registered businesses, starting with new voluntary GST registrants, so invoice data can be transmitted in a structured, consistent way. Check the latest IRAS announcements for the requirements and dates that apply to your registration.
What InvoiceNow-ready means
Your invoicing or ERP software can generate compliant structured invoices, validate them, and hand them to an accredited Access Point for transmission, without staff re-keying data.
What it is not
Emailing PDFs, sharing spreadsheets, or using a portal to retype invoices is not e-invoicing. The value comes from system-to-system structured data.
Where Digital 9 Labs fits
We are a software builder, not an Access Point. We have built an e-invoicing web app with InvoiceNow-ready workflows, and we design invoicing and ERP systems that connect to accredited providers for transmission.
