PSG vs EDG: What Replaced Them, and What Funds Custom Software Now

For years, two Singapore schemes got mixed up constantly. The Productivity Solutions Grant (PSG) and the Enterprise Development Grant (EDG) both helped fund software, but they funded different things. On 30 September 2026 both were replaced by a single scheme, the EDGE Grant. Here is what the difference was, how it maps onto EDGE, and what funds a custom build now.

EDG, PSG and MRA have been replaced by the EDGE Grant. They closed to new applications on 29 September 2026, and the EDGE Grant took over from 30 September 2026. Applications submitted before then, and projects already under way, continue under their original scheme. See what changed under EDGE and Enterprise Singapore's EDGE page.

PSG vs EDG: what was the difference?

PSG co-funded pre-approved, off-the-shelf digital solutions and equipment, such as accounting, HR, CRM, POS and inventory tools from a listed vendor: up to 50%, capped at S$30,000 a year. EDG co-funded customised projects, including custom software, with no pre-approved vendor list: up to 50% for SMEs, with no fixed cap. The rule of thumb was simple: off-the-shelf and fast, use PSG; custom-built and transformational, use EDG.

Both closed to new applications after 29 September 2026. Applications submitted before 30 September are still assessed under their original rules, and projects already under way continue to completion and claim.

What replaced PSG and EDG?

The EDGE Grant brings PSG, EDG and MRA under one scheme with over 150 activities across business areas including Automation & Digitalisation, Innovation, Internationalisation and Sustainability. Instead of choosing a grant, you choose the activity that matches your project, and the activity sets the support level, cap and vendor rules.

What PSG covered maps fairly directly: single-function digital solutions from pre-approved vendors, browsable on IMDA's SMEs Go Digital platform. What EDG covered does not map as neatly, because EDGE has no open-ended "custom project" activity. That is the change that matters most for anyone planning a bespoke build.

What funds custom software now?

The EDGE Grant, when the build fits one of its activities. Enterprise Singapore does not name a single activity for bespoke software. The clearest defined route is the integrated enterprise systems activity: a system covering at least three business functions, such as financial management, supply chain and inventory, project management or field service. Your own vendor can build it when no pre-approved package has the functions you need, though processing takes about ten weeks instead of one, and support counts toward the S$30,000 sub-cap. (EDGE FAQ)

For a larger customised project outside the standard activities, the Government has said businesses can still apply to Enterprise Singapore directly. Either way, confirm the activity with Enterprise Singapore's advisors before you apply. We cover where custom software fits, with worked examples, on our EDGE Grant page.

Can you combine activities?

Yes. The old advice was to use PSG for an off-the-shelf tool and EDG for a separate custom build. Under EDGE, the equivalent is one application per activity: you can submit several at the same time, for example a pre-approved accounting package and a separate integrated system. Two rules to remember: all activities share the S$100,000 annual cap, and you can’t claim the same cost twice. A project already funded under PSG or EDG should not apply again under EDGE.

How to apply (and the order that matters)

Sequence is everything. EDGE does not support an application if work has started, or any payment or deposit has gone to a vendor, before it was submitted:

1. Scope the project with your developer: deliverables and the productivity gains.
2. Get a proposal and quotation: the documentation your application needs. Don't sign or pay yet.
3. Apply on the Business Grants Portal from the EDGE activity page, using the Corppass BGP Preparer and Acceptor roles, and wait for approval.
4. Build, pay and claim: only after approval, with a single final claim once the work is complete and paid.

AppTech is a software developer, not a grant consultant, but an EDGE application for a custom system needs exactly what we produce: a clear scope, deliverables, and a quotation. If you’re weighing whether your project is a pre-approved tool or a custom build, our free EDGE eligibility check gives you a quick read, and the EDGE Grant page explains how we help.
