ION: A Game Changer for Indonesia's Digital Economy

Part I of a Two-Part Series

JAKARTA, Investortrust.id — For nearly two decades, Indonesia’s digital commerce landscape has expanded rapidly through centralized e-commerce marketplaces that connect buyers and sellers within closed platforms. While this model expanded market access and spawned millions of digital merchants, it created structural hurdles that hit small businesses hardest: high transaction commissions, zero inter-application interoperability, and heavy reliance on closed digital ecosystems controlled by individual tech giants.

PT Indonesia Open Network (ION) is offering a fundamentally different approach. Rather than building another e-commerce marketplace, ION is developing Digital Public Infrastructure (DPI) that allows every player in the digital trade ecosystem—marketplaces, banks, payment processors, logistics firms, and small merchants—to connect through a single, open grid. If widely adopted, ION could become a structural game-changer for how digital commerce takes place across Southeast Asia’s largest economy.

“ION is not a marketplace. ION stands for Indonesia Open Network—an open digital network that allows all players across the digital trade ecosystem to connect with one another,” Dr. Bayu Prawira Hie, President Director of PT Indonesia Open Network (ION), said in an interview with Investortrust in Jakarta on Friday, July 24, 2026.

According to Hie, digital trade has long been dominated by closed networks controlled by single corporations. Sellers, buyers, payment options, logistics, and merchant support services are kept inside a single platform, forcing all transactions to abide strictly by the platform owner's proprietary rules.

In contrast, ION is built as an open network where any market participant can join as long as they follow unified protocols and technological standards. This open architecture simplifies the growth pathway for micro, small, and medium enterprises (MSMEs), positioning ION as a potential catalyst for national economic expansion.

From Toll Roads to Open Arterial Highways

To illustrate the structural difference, Hie uses a straightforward transportation analogy. Closed platform networks function like private toll roads: every entry ramp, exit gate, rest area, and operational policy is controlled by a single authority, and every vehicle must obey that sole operator's rules.

An open network, by contrast, operates like a public arterial highway. Anyone can construct an access road, off-ramp, or roadside service center as long as they follow universal traffic laws.

“In an open network, no single entity controls the entire system. Every market participant gets an equal opportunity to compete and grow,” Hie stated.

In digital trade, this open-protocol architecture allows competing marketplaces, shopping apps, payment systems, logistics fleets, lenders, and commercial banks to interoperate seamlessly. Sellers are no longer locked into a single app, while consumers gain visibility over a far broader selection of products.

Hie emphasized that ION is not designed to compete with existing e-commerce giants. Instead, it serves as a "digital highway" where all marketplaces can scale together. Just as the internet serves as an open foundation for millions of independent websites without competing against them, ION is constructed as shared infrastructure so that disparate trading platforms can communicate with one another.

Consequently, ION does not eliminate established marketplaces; it expands their addressable markets through a unified network. “What we are building is the underlying infrastructure. Marketplaces remain intact, but they can all connect through the exact same network,” Hie said.

Slashing High Digital Transaction Costs

The primary friction point ION seeks to solve is high digital transaction fees. According to Hie, while millions of Indonesian small businesses recognize the value of e-commerce, many remain hesitant to digitize because heavy platform commission fees erode their profit margins.

Within the ION network, competing marketplaces will vie to attract sellers by offering lower commission rates. This open-market competition is expected to push transaction costs down below 10%.

Lower transaction fees allow merchants to preserve profit margins without raising retail prices. “When costs drop, prices become more competitive. Sellers remain profitable, buyers get cheaper prices, and transactions happen much more smoothly,” Hie said.

He noted that under high-fee structures, merchants often mark up prices to recover platform costs, driving buyers away. When overhead falls, both buyers and sellers win.

From a macro standpoint, this dynamic creates a powerful ripple effect: competitive pricing drives consumer demand, rising demand boosts transaction volumes, and higher volume drives production and income—accelerating overall digital economic growth.

The Strategic Role of Commercial Banks

One of ION’s distinct advantages is its ability to directly bridge commercial banking with digital retail. Indonesian banks maintain millions of active mobile banking users but lack the merchant networks built by e-commerce platforms.

Through ION, mobile banking applications can connect directly to merchant catalogs across the network without having to build proprietary e-commerce platforms from scratch. Bank customers gain access to a wider array of goods, while merchants unlock immediate access to millions of new prospective buyers across banking user bases.

Logistics companies, digital payment gateways, fintech lenders, and software platforms can similarly plug into the same open architecture.

Supporting 65 Million Small Businesses and Solopreneurs

For Indonesia, ION’s most significant impact lies in expanding MSME digitalization. Indonesia is home to roughly 65 million micro, small, and medium enterprises, yet the vast majority have not fully leveraged digital commerce due to technical onboarding hurdles or high platform fees relative to earnings.

ION is built to remove these barriers. Merchants can choose whichever marketplace or service provider offers the most efficient rates, as all platforms compete openly on the network.

Greater choice strengthens merchants' bargaining power. Beyond traditional MSMEs, ION lowers entry barriers for individual "solopreneurs".

Previously, solo entrepreneurs faced two costly paths: spending heavily to build custom mobile apps or joining major e-commerce platforms that charged steep commissions. Open networks drastically reduce these overhead costs.

This shift aligns with Indonesia's legal framework for Sole Proprietorships (PT Perorangan). As long as a solopreneur holds a Business Identification Number (NIB), they can operate legally, access formal credit, and trade across open digital channels.

Open-Source Architecture and Digital Sovereignty

ION is built on open-source technology, preventing vendor lock-in to proprietary tech providers. This approach allows multiple stakeholders to continuously develop the system, driving down development costs and accelerating localized innovation.

It also strengthens national technological sovereignty by ensuring the country's core commercial rails do not depend entirely on foreign or closed proprietary software.

ION’s design is inspired by the success of India’s Open Network for Digital Commerce (ONDC), developed by New Delhi to connect all market players onto a unified national trading grid.

A clear example of this model's impact occurred in India's ride-hailing sector. Before ONDC, dominant ride-hailing platforms charged driver commissions as high as 30% to 35%. Through Namma Yatri—a driver-community app built on the open ONDC protocol—commission fees plummeted to around 5%, boosting driver earnings while lowering consumer fares.

Hie asserts that the same principle applies to Indonesian retail trade: "As competition opens up, transaction fees will be dictated by true market dynamics. That creates operational efficiency for businesses and delivers direct savings to consumers," he stated.

Building an Inclusive Digital Economy

The future of digital trade will no longer be dictated by who holds the most locked-down ecosystem, but by who provides the most efficient service at the lowest cost.

ION is not designed to replace established tech giants, but to serve as shared infrastructure where every market participant can scale within an open, competitive, and inclusive framework.

If successfully scaled, ION will not only accelerate the digital onboarding of millions of Indonesian small businesses, but structurally re-engineer national e-commerce from a fragmented, closed-platform economy into a fully interconnected network economy.

The Paradigm Shift: From Platform Economy to Network Economy

Global digital commerce is entering a new era. While the past decade was defined by the "platform economy"—where centralized tech companies funnel all transactions into single, walled-garden applications—the market is shifting toward a "network economy" grounded in open, interoperable rails.

In a platform economy, economic value concentrates heavily with the platform owner, who controls merchant access, sets transaction rules, and extracts rents. While this model accelerated initial digitization, it created market concentration and vendor lock-in.

In a network economy, value is generated through seamless interoperability. The network itself becomes the utility, enabling thousands of independent applications, financial institutions, and merchants to build services on top of a shared standard.

This evolution mirrors the global push for Digital Public Infrastructure (DPI) advocated by the G20, World Bank, and United Nations. Much like physical highways, deepwater ports, or electrical grids, DPI serves as essential economic infrastructure—providing secure, open, and inclusive rails for digital identity, instant payments, data exchange, and digital trade.

India pioneered this approach through its "India Stack," integrating Aadhaar digital IDs, the Unified Payments Interface (UPI), digital document registries, and ONDC. India's model demonstrated that governments do not need to build state-owned marketplaces; they simply need to pave the "digital highway" so that competing private players, logistics providers, banks, and small merchants can trade freely.

ION applies this exact thesis to Indonesia. By providing open digital rails, ION creates a compounding network effect: merchants gain broader audience reach, consumers enjoy transparent pricing, banks unlock new distribution channels, and small businesses scale efficiently.

Just as physical toll roads accelerated the movement of physical goods, open digital trading networks accelerate the flow of capital, data, and innovation—paving the way for an open, competitive, and digitally sovereign economy.
