Context
Small and medium enterprises (SMEs) form the backbone of global supply chains, accounting for approximately 90% of businesses and over half of global employment, yet their access to supply chain finance (SCF) remains severely limited. According to the ICC Trade Register, the combined exposures tracked across trade finance instruments – including SCF – represent approximately 5% of global trade flows and 18% of financed trade flows, yet most SCF programmes disproportionately benefit larger suppliers.
Meanwhile, the Asian Development Bank (ADB) estimates the global trade finance gap at US $2.5 trillion – a figure that has held steady since 2023 and represents around 10% of global trade – with SMEs historically the most underserved segment. ADB’s Trade and Supply Chain Finance Program has facilitated over 104,000 transactions worth US$74 billion since 2009, and while SME rejection rates have recently narrowed, significant structural barriers remain.
Consequences of the participation gap include:
- Higher supply risk and fragility – Excluding SMEs, particularly from deep-tier financing, increases supply chain vulnerability and exposure to disruption.
- Slower cash conversion – Delayed access to liquidity limits SME agility, constrains growth, and undermines working capital efficiency.
- Missed ESG and diversity goals – Large buyers often lack visibility into SME practices around emissions, labour standards, and sourcing, creating blind spots in their sustainability strategies. According to McKinsey, supply chains account for more than 80% of a company’s greenhouse gas emissions. Yet SMEs – estimated to need to fund roughly half of the US $100 trillion required for net-zero supply chains by 2050 – remain largely excluded from green finance programmes.
How SMEs function within the SCF ecosystem
SMEs are not passive recipients of supply chain finance – they are active participants whose data, liquidity needs, and supply chain positions shape how SCF programmes operate.
- Early payment and data providers: SMEs generate the transaction data (invoices, purchase orders, delivery confirmations) that SCF platforms use to assess risk and automate financing decisions. Their participation reduces the ecosystem’s reliance on expensive short-term lending.
- Liquidity drivers for ecosystem liability: Because SMEs operate with tight cash flows, faster access to working capital through SCF directly reduces the risk of supply disruptions and supports reliable delivery across the chain.
- Catalysts for ESG and diversity goals: Inclusive SCF programmes give anchor buyers a practical mechanism to meet sustainability and supplier diversity commitments by extending financing to smaller, women-led, and regional businesses.
- Risk concentration beyond tier-1: Most operational and financial risk in a supply chain sits with SMEs in deeper tiers, not with tier-1 suppliers. Bringing them into SCF reduces systemic risk concentration and improves supply chain predictability.
- Drivers of agility and market reach: SMEs contribute flexibility and innovation to supply chains. Access to SCF enables them to scale and participate in cross-border trade, strengthening overall competitiveness.
Why SMEs matter to the global economy
SMEs are not just supply chain participants, they are a cornerstone of the global economy and their financial exclusion has consequences far beyond any single supply chain.
- Scale and reach: SMEs constitute around 90% of businesses worldwide and account for over half of global employment. As suppliers, distributors, and service providers, they underpin the operations of large corporations across every major industry.
- Economic output: SMEs contribute significantly to GDP in both developed and emerging markets. In many developing economies, they represent the primary engine of job creation and income generation, making their financial health inseparable from broader economic stability.
- Systemic vulnerability: When SMEs are excluded from financing, the consequences are not contained to individual firms. Fragility accumulates across tiers, creating systemic risk that eventually surfaces as supply shocks – as seen during the COVID-19 pandemic and subsequent supply chain disruptions.
- Risk diversification for buyers: Financially stable SMEs mean fewer supply disruptions. When SMEs are solvent and liquid, large buyers benefit from greater supply chain continuity, reducing exposure to insolvency-driven delays or sudden supplier failures.

Barriers that keep SMEs out of SCF
Despite SCF’s potential, SMEs remain largely excluded due to persistent frictions across commercial, operational, and regulatory layers. Onboarding is slowed by heavy Know Your Customer (KYC) & Ultimate Beneficial Owner (UBO) checks. Credit models still hinge on collateral & binary approvals. Programme designs favour large anchors, with high entry thresholds and complex discount mechanics. Operational hurdles – invoice disputes, long approvals, and data mismatches – erode trust, while manual workflows and small ticket sizes make cost-to-serve uneconomical, particularly for cross-border flows. Without structural change, SCF remains out of reach for most SMEs.
Examples of barriers
- Onboarding friction: Heavy KYC and Know Your Business (KYB) requirements, UBO checks, documentation overload, and lack of multilingual support all slow SME participation before financing even begins.
- Credit and risk models: Dependence on thin credit files, collateral demands, and rigid underwriting frameworks systematically exclude SMEs that lack the financial history large institutions require.
- Program design flaws: An anchor-only focus, high entry thresholds, and complex discounting mechanics make most SCF programmes structurally inaccessible to smaller suppliers.
- Process realities: Invoice disputes, prolonged approval timelines, and data mismatches undermine confidence and delay the liquidity SMEs need most.
- Cost to serve: Manual workflows, low transaction values, and cross-border compliance burdens make SME financing uneconomical for many financiers under current operating models.
What financiers and platforms must do differently
To make supply chain finance work for SME economics, financiers and fintechs need to rethink both their products and their operating models. Traditional balance-sheet underwriting is too rigid for small businesses. Instead, alternative data, such as e-invoices, logistics records, VAT filings, and open banking feeds, combined with anchor confirmations, should drive behavioural risk assessment.
Financing must be flexible, offering micro-limits, dynamic credit lines, instant settlement, and API-based onboarding for speed and scale. Robust fraud and dilution controls, including invoice invalidation, assignment tracking, and credit insurance, are essential to maintain trust. Platforms must also support multi-currency and cross-border flows with lightweight FX options to enable broader global trade participation.
Possible improvements to make SCF work for SMEs
- Digitisation as the core enabler: Transitioning from paper-heavy workflows to digital-first models, leveraging e-invoices, GST data, and API integrations, can cut onboarding time dramatically – from weeks to hours.
- Alternative data for smarter risk assessment: Moving beyond balance-sheet dependency means using verified trade signals such as e-invoices, logistics data, VAT filings, and open banking feeds, combined with anchor confirmations, to build a more accurate picture of SME creditworthiness.
- SME-friendly product features: Micro-limits, dynamic credit lines, and instant settlement are designed to match SME cash cycles. API-based onboarding ensures seamless integration for small suppliers without heavy administrative burden.
- Robust fraud and dilution controls: Invoice invalidation checks, assignment tracking, and credit insurance help prevent double-financing and mitigate risk without placing the compliance burden solely on SMEs.
- Multi-currency and cross-border capability: Lightweight FX options and cross-border settlement capabilities allow SMEs to participate in global trade without being penalised by currency complexity or correspondent banking costs.
Policy and market enablers
Building inclusive SCF markets does not require complex regulatory overhauls – it depends on a handful of targeted interventions. Mandating e-invoicing and enabling interoperable digital identities and signatures create the foundation for trust and automation. Secured transaction registries strengthen enforceability and reduce fraud risk.
Proportional, risk-based KYC norms for low-risk SCF products can ease SME onboarding without compromising compliance. And sharing credit data publicly, alongside guarantee programmes offered through development finance institutions (DFIs), can attract private lenders and meaningfully expand SME funding. Together, these measures can shift SCF from a niche offering into a mainstream market standard.
Key enablers
- E-invoicing mandates, interoperable digital IDs and signatures, and secured-transaction registries: Digital mandates ensure verified trade events and legal enforceability, reducing fraud and enabling automated financing decisions.
- Proportional, risk-based KYC for low-risk SCF products: Simplified onboarding for small-ticket, short-tenor transactions lowers barriers for SMEs while maintaining compliance standards.
- Public credit-data sharing and DFI guarantee schemes: Open credit registries and partial-risk guarantees attract banks and fintechs to fund SMEs at scale, reducing concentration risk and crowding in private capital.

Anchor buyers as catalysts for inclusive SCF
Anchor buyers hold the key to building truly inclusive supply chain finance ecosystems – yet many current programmes remain burdened by supplier paperwork and rigid onboarding thresholds that create friction and exclude smaller players. The opportunity lies in redesigning these programmes so that payables certainty becomes the foundation for financing, rather than documentation volume.
This shift requires changes on several fronts:
- Publish transparent acceptance and dispute policies: Clear, consistent payables policies protect the certainty that financiers need to price and commit to transactions, building confidence across the ecosystem.
- Move beyond spend-based segmentation: Prioritising suppliers by their importance to operational continuity, or by their position in underserved segments, produces more resilient and inclusive outcomes than tiering purely by transaction volume.
- Simplify onboarding: Removing minimum spend thresholds and offering multilingual, assisted onboarding experiences directly expands the pool of participating suppliers.
- Extend access beyond tier-1: Milestone-based financing and buyer-nominated tier-2 vendor programmes can cascade SCF benefits deeper into the supply chain, where financing gaps are most acute.
- Share surplus benefits openly and measure fairness: Distributing the economic benefits of SCF openly, and tracking equitable outcomes alongside efficiency metrics, builds the trust that sustains long-term supplier participation.
By cascading access deeper into the supply chain, sharing gains transparently, and tracking equitable outcomes, anchor buyers can transform SCF from a compliance-heavy process into a seamless, fair, and growth-enabling platform.
A blueprint for change
Transforming fragmented SME inclusion into a true market standard requires a shift in focus – from closing credit gaps to enabling risk-sharing and aligned incentives across the ecosystem. Financing should be anchored on the buyer’s commitment and verified trade milestones, not on thin SME credit files.
Digital, interoperable signals – purchase orders, goods receipt notes, e-invoice clearance, and buyer acceptance – must replace cumbersome paperwork to deliver the trust and speed that SME financing demands. A contestable market with multiple funding rails and portable identities will foster competition and discipline pricing, and prevent platform lock-in.
Simple, stable rules on assignability, acceptance, and dispute resolution are the foundation for fast, predictable liquidity – making SCF access broad-based and inclusive rather than concentrated among a handful of large, well-connected suppliers.
- Finance the buyer’s promise, not the SME’s history: Anchor funding on purchase commitments and confirmed trade milestones – PO issuance, goods receipt, e-invoice clearance – rather than on limited SME credit histories.
- Prefer interoperable digital signals over paper: Standardised, machine-readable trade signals that reduce friction, improve trust and enable automated financing decisions at scale.
- Keep markets contestable: Multiple funders and funding rails, combined with portable identities and documents, strengthen competition, improve pricing, and reduce dependency on any single platform.
- Adopt minimal, stable rules: Clear norms on assignability, acceptance, and dispute resolution reduce uncertainty and operational risk for all parties.
- Embed predictable liquidity into everyday trade: Fast, reliable cash flows built into standard trade processes benefit broad segments of the supply chain, not just large or well-capitalised players.

Making SCF work for everyone
SMEs form the backbone of global supply chains, yet they remain the most underserved segment in supply chain finance. Closing this gap demands a fundamental shift – away from credit-centric models and towards risk-sharing frameworks anchored on buyer commitments and verified trade events.
Digital interoperability, contestable markets, and simplified onboarding are not optional enhancements – they are the infrastructure required to embed predictable liquidity into everyday trade. But, technology alone is not enough. Aligning incentives across anchors, financiers, fintechs, and policymakers is what will determine whether SCF becomes a genuinely inclusive tool or remains concentrated among those who need it least.
The opportunity is significant. By shifting the foundation frombyreditworthiness to commitment, and from documentation to verified digital signals, supply chain finance can become a mainstream enabler of resilience, inclusivity, and sustainable growth – for SMEs and the global economy they support.
