If you’re running a GST-registered business in Singapore, you’ve probably heard the term “InvoiceNow” floating around. Maybe your accountant mentioned it, maybe you spotted it in an IRAS circular. But what does it actually mean for how you get paid?
Here’s the short guide: InvoiceNow is Singapore’s national e-invoicing network, built on Peppol invoicing. IRAS is progressively mandating its use for GST-registered businesses, starting with new voluntary registrants and expanding to cover everyone by April 2031. It changes how invoice data moves between your business, your clients, and the tax authority. But it doesn’t replace the need to collect payment.
Here’s what you should know about InvoiceNow and what digital invoicing means for payments in Singapore.
Key Takeaways
- InvoiceNow Standardises Digital Invoicing: InvoiceNow is Singapore’s nationwide e-invoicing network, built on the international Peppol standard, enabling structured digital invoices to be sent directly between accounting systems and to IRAS.
- Mandatory Adoption Is Being Rolled Out Gradually: IRAS is rolling out mandatory participation in phases, from November 2025 for newly incorporated voluntary GST registrants through to April 2031 for all remaining GST-registered businesses.
- Invoice Data Must Be Submitted Through the Network: The mandate requires GST-registered businesses to transmit invoice data to IRAS via the InvoiceNow network, replacing unstructured formats like PDFs for tax reporting purposes.
- Businesses Gain Efficiency and Compliance Benefits: Benefits include faster GST refunds, reduced audit burden, fewer invoicing errors, and shorter payment cycles between trading partners already on the network.
- Support Is Available for SMEs: SMEs can access InvoiceNow-Ready Solutions at no cost until March 2031, and government grants of up to S$1,000 are available for smaller businesses to offset adoption costs.
- Payments Still Need to Be Collected: While InvoiceNow handles invoice transmission, businesses still need a reliable way to collect the actual payment. Pairing e-invoicing with a payment link for business use closes the loop between billing and collection.
InvoiceNow in Singapore Explained: What is It?
In 2019, IMDA launched InvoiceNow in Singapore. It’s built on Peppol, an international e-invoicing framework used across Europe, Australia, and parts of Asia. The idea is simple: instead of sending invoices as PDFs or paper documents, businesses transmit them in a structured digital format that both accounting systems and government agencies can read automatically.
When you send an invoice through the InvoiceNow network, it goes from your accounting software to the recipient’s system via an IMDA-accredited Access Point Provider. If you’re GST-registered and under the mandate, a copy of that invoice data also goes directly to IRAS. There are no manual uploads or separate GST filing prep for those transactions.
Over 63,000 businesses are already on the network, and the government has been on it since 2020 as an invoice recipient. So if you’re doing any B2G work, this is already relevant to your operations.
The IRAS Mandate: Who It Affects and When
The rollout is phased, and the timelines are now confirmed. Here’s how it breaks down:
- 1 May 2025: Soft launch. Any existing GST-registered business can voluntarily start transmitting invoice data.
- 1 November 2025: Mandatory for newly incorporated companies (those incorporated within six months of their GST application) that register for GST voluntarily.
- 1 April 2026: Mandatory for all new voluntary GST registrants, regardless of incorporation date.
- 1 April 2028: Extends to new compulsory GST registrants and existing businesses with annual supplies of S$200,000 or less.
- 1 April 2029: Existing businesses with annual supplies up to S$1 million.
- 1 April 2030: Existing businesses with annual supplies up to S$4 million.
- 1 April 2031: All remaining GST-registered businesses.
IRAS has said it will notify businesses registered before 2026 of their specific implementation dates by mid-2026. In the meantime, there’s an Excel calculator on the IRAS website to help you figure out where you fall.
Also, it’s worth noting that overseas entities and businesses registered solely under the Reverse Charge regime are exempt.
What This Changes for Your Payment Collection Workflow
For most SMEs, the biggest practical change is switching from PDF or paper invoices to a digital invoicing format that your accounting software transmits automatically. If you’re already using cloud accounting tools like Xero, QuickBooks, or similar platforms, many of them are already InvoiceNow-ready or working towards it. The transition might be as straightforward as activating a feature and registering for a Peppol ID.
The compliance benefit of digital invoicing for payments in Singapore is real: once your invoice data flows directly to IRAS, your GST return preparation gets simpler. IRAS can automatically cross-check your data, potentially leading to faster audits and quicker GST refunds. For businesses that regularly claim input tax, that’s a genuine cash flow advantage.
But there’s one important catch: Peppol invoicing handles the invoice itself, the document, the data, and the transmission, but it doesn’t handle collecting the money. You still need a way to receive payment from your client once the invoice lands.
In other words, if your current process involves sending a PDF and hoping the client pays within 30 days, switching to e-invoicing makes the invoice arrive faster and more reliably, but it doesn’t change whether the client pays on time.
Where InvoiceNow Stops and Payment Collection Starts
Many businesses face a gap where they invest time getting InvoiceNow set up, but then still rely on manual bank transfers, handwritten PayNow references, or “please remit to the account below” footnotes on their invoices. That’s a lot of friction between issuing an invoice and actually getting paid.
One practical approach is to pair your e-invoicing workflow with a payment link embedded in the invoice or sent alongside it. The client receives the invoice via the Peppol network, and a payment link provides an immediate way to settle it by card, PayNow, or bank transfer, without having to enter account details manually.
This complements InvoiceNow, as the invoice transmission meets the IRAS requirement, while the payment link handles the actual collection. Together, they shorten the cycle from “invoice sent” to “cash received” in a way neither tool can achieve on its own.
Getting Ready Without Overcomplicating It
If your mandatory date isn’t until 2028 or later, you might be tempted to push this aside. But there are reasons to act sooner rather than later.
- The government is offering financial support. SMEs can access InvoiceNow-Ready Solutions at no cost until March 2031, and grants of up to S$1,000 are available through IMDA to help smaller businesses cover adoption costs. Waiting delays the benefit instead of saving you money.
- Network effects matter. The more businesses on InvoiceNow, the more useful it becomes. If your suppliers and clients are already on the network, your invoice process will be faster on both ends. Early adoption puts you ahead of trading partners who’ll scramble later.
- It’s much less stressful. Getting familiar with the system now and configuring it are much easier and less stressful when there’s no deadline pressure.
Pair Smarter Invoicing with Faster Payment Collection
With InvoiceNow explained, it is a genuine step forward for tax compliance and invoicing efficiency in Singapore, reducing manual processing, cutting error rates, and giving IRAS the data it needs without extra work on your end.

Frequently Asked Questions About InvoiceNow
Does InvoiceNow replace my existing invoicing software?
Not necessarily. Many popular cloud accounting platforms are already InvoiceNow-ready or working towards compatibility. In most cases, you’ll activate the InvoiceNow feature within your existing software rather than switching to an entirely new system. You’ll also need to register for a Peppol ID through an IMDA-accredited provider.
Does InvoiceNow help me get paid faster?
InvoiceNow speeds up invoice delivery and processing, reducing the time between when you send an invoice and when your client receives it. However, it doesn’t process the actual payment. Pairing e-invoicing with tools like payment links can help close the gap between invoice delivery and cash collection.
Is there financial support available for businesses adopting InvoiceNow?
Yes. IMDA offers grants of up to S$1,000 for SMEs and up to S$5,000 for larger businesses to offset adoption costs. SMEs can also access InvoiceNow-Ready Solutions at no cost until March 2031. Additional support is available through the Productivity Solutions Grant for eligible IT solutions.
