Today on The Merchant Desk: NPCI formalizes the revenue waterfall for India's incoming merchant fees, West Africa mandates regional instant payment interoperability, and enterprise software vendors race to manage token-driven margin decay.
Yesterday we covered non-bank payment aggregators negotiating for a share of the 0.4% enterprise UPI MDR taking effect October 15; today the National Payments Corporation of India outlined the exact revenue distribution framework. Under the structure, customer issuing banks receive 40%, merchant acquiring banks receive 30%, the UPI application captures 20%, and supporting banks receive 10%. Non-bank aggregators like Razorpay, Cashfree, and Pine Labs receive no direct allocation and must negotiate bilaterally with acquiring banks for 50% to 80% of the acquiring share.
Why it matters
The formalization of the UPI MDR waterfall establishes definitive unit economics for digital acquiring in India after years of zero-fee mandates. By allocating the largest share to issuing banks, the framework heavily rewards consumer account acquisition while squeezing non-bank aggregators into tough revenue-share negotiations. For payment infrastructure operators, survival depends on possessing enough merchant distribution leverage to command a larger split from acquiring partners.
Financial analysis published on Friday details Adyen's underlying operational leverage, noting that a single basis point shift in net take rate impacts annual net revenue by approximately €161 million. Adyen generated €1.303 billion in H1 2026 net revenue on €803.8 billion in processed volume, representing an annualized volume of €1.608 trillion. The figures illustrate the company's high sensitivity to pricing negotiations with enterprise merchant clients.
Why it matters
Adyen's financial metrics demonstrate the extreme volume reliance of global enterprise payment acquirers. As large global merchants push for interchange-plus pricing compression, maintaining net margin requires cross-selling value-added software like automated routing, fraud scoring, and tokenization. For competing payment orchestration platforms, matching Adyen's single-platform cost efficiency remains the primary hurdle to winning enterprise volume.
Ahmedabad-based industrial marketplace Pneucons announced on Sunday that it will stop accepting UPI payments on October 10 ahead of the incoming 0.4% enterprise MDR framework we've been tracking. Co-founder Pritesh Lakhani explained that calculating the 0.4% fee on the total customer payment including GST consumes approximately 94% of Pneucons's 0.5% pre-GST order commission. While small vendors earning under ₹1 lakh monthly remain exempt, thin-margin B2B marketplaces face severe working capital depletion.
Why it matters
Pneucons's decision reveals a critical operational friction in fee structures that calculate merchant discount rates on gross sales totals rather than net platform fees. For B2B marketplaces operating on fractional commissions, passing through value-added tax alongside payment processing fees completely cannibalizes profit margins. This creates an immediate incentive for low-margin platforms to steer high-value transactions back to direct bank transfers or traditional invoicing.
Product releases on Monday from Feedzai—introducing RiskOps Studio to combine risk management workflows—and core banking vendor Mambu—introducing Intelligent Core to link AI agents directly to core ledgers—mark a structural convergence in banking infrastructure. Historically bought as isolated point solutions, real-time risk decisioning and ledger balances are being unified to streamline real-time transaction processing and meet stricter regulator expectations.
Why it matters
Operating separate risk engines and core banking ledgers creates processing latency and synchronization failures during high-frequency instant payment routing. Merging risk evaluation directly into the core ledger allows digital banks and embedded finance platforms to evaluate credit, fraud, and liquidity simultaneously. For fintech operators, this architecture cuts compliance overhead and eliminates brittle middleware integrations.
Sanlam confirmed plans on Monday to soft-launch a retail credit and banking offering to staff in November 2026 ahead of a full public rollout in Q1 2027. Partnering with GoTyme Bank to form a consumer credit joint venture, Sanlam targets its 10 million client base and is expanding its physical presence to 200 retail outlets. However, corporate expenses rose to R374 million in H1 2026 due to banking enablement costs, and its developing credit and banking unit posted a R179 million loss.
Why it matters
Sanlam's push into transactional banking highlights how South African life insurers are racing to capture primary bank accounts to counter slowing organic growth in legacy insurance. Utilizing GoTyme's digital stack limits fixed IT capital expenditure, but physical branch costs and initial credit segment losses demonstrate the high cash burn required to challenge Capitec and Discovery Bank. The venture tests whether an established insurer brand can successfully convert policyholders into active transactional banking clients.
The Central Bank of West African States (BCEAO) announced that its PI-SPI instant payment platform will become mandatory for all electronic money transactions across the eight UEMOA nations on November 2, 2026. The reform makes daily domestic P2P transfers of 8,000 CFA francs or less free while introducing new provisions for third-party API business models. While 175 financial institutions covering 38 million users are authorized on the rail, only 24 entities currently hold API Business approval.
Why it matters
Mandating PI-SPI interoperability eliminates the proprietary closed-loop advantages previously enjoyed by dominant telecom wallets in West Africa. Capping fees on micro-transfers forces mobile money operators to shift from transaction fees toward embedded credit, payroll processing, and merchant acquiring tools. For regional fintechs, acquiring API Business status before November is essential to capturing third-party merchant routing opportunities.
Mastercard entered into strategic partnerships on Sunday with The Mojaloop Foundation and AfricaNenda to deploy AI-powered fraud prevention across African instant payment systems. The collaboration will integrate Mastercard's A2A Protect risk-scoring engine directly into Mojaloop's open-source payment software. Across 31 African countries, 36 live instant payment rails processed nearly $2 trillion across 64 billion transactions in 2024, yet 15% of surveyed adults report encountering daily financial scams.
Why it matters
As account-to-account (A2A) payment volume accelerates across Africa, open-source payment switches lack embedded risk infrastructure to combat authorized push payment fraud and mule accounts. Embedding network-grade AI scoring into Mojaloop's core architecture allows non-bank processors and regional switches to catch fraudulent transfers in real time without building expensive custom risk models. This lowers the security barrier for domestic instant rails challenging credit card networks.
Mastercard and DPO Group launched a partnership in Ghana on Monday enabling local businesses to accept card, mobile money, and e-wallet payments through a unified gateway with chargeback protection. Bank of Ghana data shows monthly mobile money volume reached GH¢492.9 billion across 954 million transactions in June 2026, yet census figures reveal only 37% of Ghanaian businesses accept digital payments. The initiative connects acceptance with supply-chain financing via partnerships with Boost and Smile ID.
Why it matters
The massive disconnect between Ghana's 26 million active mobile money consumer wallets and a 37% merchant acceptance rate highlights the bottleneck in emerging-market acquiring infrastructure. By bundling multi-rail acceptance with automated identity checks and working capital credit, Mastercard and DPO are attempting to digitize B2B trade supply chains. For merchant tech operators, success hinges on converting informal cash-based supplier payments into trackable digital ledger entries.
Building on the agentic identity verification and credential protocols we've been tracking, autonomous travel platforms are overhauling payment execution by deploying single-use virtual credit cards and cryptographic verification layers to control agent purchases. Industry partnerships involving eDreams ODIGEO with Visa, Mastercard's Agent Suite, and Amex's ACE developer kit provide structured authorization rails, while fintech provider Corpay enables AI agents to auto-generate dynamic virtual cards with strict spending limits and merchant category locks.
Why it matters
Granting autonomous AI agents unrestricted access to static stored corporate cards exposes enterprises to severe financial loss from prompt injection attacks or model hallucinations. Programmatic single-use virtual cards isolate financial risk by constraining transactions to exact amounts, merchant IDs, and expiration windows. For commercial card issuers, building real-time virtual card APIs for AI software is rapidly becoming a core requirement for enterprise expense management.
Following earlier projections we tracked of a R2.89 per litre increase, Shiprazor published analysis on Sunday warning that South African e-commerce merchants and logistics operators face severe margin compression as final diesel price increases are set to exceed R3 per litre on October 7. While SA online retail spend is projected to reach R159 billion in 2026, hidden fulfilment losses—such as failed delivery attempts, return processing, and packaging errors—are eroding courier profits. According to the 2026 Online Retail in SA report, shipping fee friction caused cart abandonment for 51.7% of online merchants.
Why it matters
Rising fuel prices directly inflate last-mile logistics expenses across South African e-commerce, forcing merchants to choose between absorbing delivery losses or raising checkout shipping fees. Higher shipping surcharges trigger immediate cart abandonment among price-sensitive consumers, threatening retail gross merchandise value. Merchant tech providers must deploy automated multi-courier routing and real-time address validation to minimize failed delivery attempts.
Microsoft open-sourced the original Zork text-adventure trilogy—comprising Zork, Zork II, and Zork III—under the permissive MIT License on Monday. Executed through a joint initiative between Microsoft's Open Source Programs Office, Xbox, and Activision, the release clears up decade-long licensing ambiguities surrounding Infocom's original Z-Machine code. The repository allows complete public access to inspect, compile, and distribute the foundational parser-based source code.
Why it matters
Microsoft's decision to place commercial gaming history directly into the public domain under the MIT License establishes an important precedent for corporate software preservation. Resolving complex rights chains across acquired intellectual property allows researchers and developers to freely adapt vintage Z-Machine virtual machine logic for modern operating systems.
Building on the API pricing clashes and transition away from seat-based licensing we've been tracking across the enterprise SaaS stack, AI metering startup Vayu launched its Revenue Intelligence Hub on Friday. The platform provides enterprise finance teams with continuous customer-level profitability tracking to counter variable token compute costs, combining real-time data metering, automated revenue contract extraction, and an AI Insights Agent to catch margin erosion. Vayu highlighted findings from a joint report with PwC showing that 71% of software finance teams currently experience revenue leakage under hybrid usage pricing.
Why it matters
The rapid migration from seats to consumption-based AI features has broken traditional SaaS gross margins, leaving software vendors exposed to unprofitable enterprise power users. When variable model inference fees fluctuate while customer contract pricing remains static, finance teams face severe margin decay. Real-time metering platforms like Vayu allow software operators to dynamically track cost-to-serve per account and restructure pricing terms before contract renewals.
Waterfall Splits Shift Power to Issuing Banks NPCI's formal 40:30:20:10 revenue distribution for UPI transactions above ₹2,000 guarantees issuing banks the largest share of fees, forcing payment aggregators to negotiate bilaterally for acquiring margins.
GST-Inclusive Fee Calculations Squeeze Low-Margin Marketplaces When payment processing fees apply to gross sales rather than net commissions, low-margin B2B platforms face severe cash-flow lockups, driving some merchants to drop real-time digital rails entirely.
Central Bank Mandates Target Closed-Loop Mobile Wallets Regulators in West Africa and East Africa are enforcing open API standards and interoperable switches to disassemble proprietary wallet ecosystems and establish real-time public utilities.
Programmable Virtual Cards Protect Agentic Checkout To prevent prompt injection and model hallucinations from causing unconstrained spending, autonomous travel and commerce platforms are deploying single-use virtual cards with strict category and budget controls.
Variable Token Costs Force Real-Time SaaS Margin Tracking The transition from fixed per-seat pricing to usage-based AI workflows is driving software vendors to integrate real-time token metering and continuous contract ledger matching to prevent account-level losses.
