StoneCo (STNE): Customer relationships and what the TOTVS deal signals to investors

StoneCo provides integrated fintech services to merchants across Brazil, monetizing through transaction processing fees, merchant services, software and value-added products sold to point-of-sale, online and mobile channels. The company combines acquiring, payments infrastructure and software relationships with ISVs and retail partners to lock in recurring economics and cross-sell higher-margin services. For investors assessing customer risk and revenue durability, the key questions are partner concentration, the criticality of payments to merchants, and how non-core software dispositions reshape go-to-market focus.

One-line deal snapshot: TOTVS buys Linx and related software assets

According to a Simply Wall St note dated March 10, 2026, TOTVS S.A. entered a definitive agreement to acquire Linx and certain other software assets from StoneCo in a transaction valued at BRL 3.0 billion. This transaction reflects a strategic divestiture of software assets by StoneCo to a major Brazilian enterprise software vendor. (Simply Wall St, March 10, 2026.)

Why this transaction matters for StoneCo’s customer strategy

The sale of Linx-related software assets to TOTVS represents a re-focusing of StoneCo toward its payments and merchant-services core while transferring software product ownership to a company with a stronger enterprise ERP and retail software footprint. For investors, the deal is consequential because it changes the shape of StoneCo’s partner ecosystem: a former in-house software offering will now be operated by an external vendor that is also a large customer and channel for retail solutions. This can increase distribution efficiency while concentrating counterparty risk around a smaller set of enterprise partners.

Operating-model signals investors should weigh

With no contract-level constraints returned in the review, assess StoneCo’s operating model using company-level indicators and the facts of the TOTVS deal:

  • Contracting posture — platform provider with partner integrations. StoneCo runs merchant-facing payment rails and partners with software vendors and ISVs, which implies negotiated commercial terms that balance per-transaction economics with platform access.
  • Concentration — meaningful exposure to Brazil and to strategic partners. StoneCo’s business is predominantly Brazil-focused; partner consolidation or large third-party acquirers (like TOTVS) can materially affect distribution and upsell dynamics.
  • Criticality — payments are mission-critical for merchants. Payment processing is essential to merchants’ daily operations, providing StoneCo high retention potential and recurring revenue, which supports its strong operating margin profile.
  • Maturity — profitable and substantial scale, but still dependent on partner evolution. StoneCo shows durable profitability metrics: Revenue (TTM) of $13.399B, gross profit of $10.034B, operating margin of 46.3% and a profit margin of 17.3%, indicating mature economics in the payment stack even as sales growth requires partner-led expansion.

These signals form a cohesive picture: StoneCo is a high-margin fintech platform with strategic partner dependencies that drive growth and distribution but also concentrate counterparty risk.

Relationship-by-relationship briefing (complete coverage)

TOTVS S.A.: TOTVS agreed to acquire Linx and certain other software assets from StoneCo in a transaction valued at BRL 3.0 billion, effectively transferring ownership of specified software lines to a major Brazilian enterprise software provider and channel partner. According to a Simply Wall St report dated March 10, 2026, this was executed as a definitive acquisition agreement. (Simply Wall St, March 10, 2026.)

Risk factors and what to monitor next

  • Partner consolidation risk. When a large software vendor like TOTVS takes ownership of assets that were formerly part of StoneCo’s ecosystem, distribution advantages can accelerate—but StoneCo’s dependence on partner goodwill and technical integration becomes more concentrated.
  • Revenue mix shift. The disposition of software assets alters the product portfolio and could increase the relative share of transaction-based revenue, which increases sensitivity to volume cycles and merchant activity.
  • Regulatory and market concentration. StoneCo’s exposure to Brazil implies regulatory and macroeconomic sensitivity; investors should watch local payment rules, interchange regulation, and merchant credit cycles.
  • Execution risk on cross-sell. StoneCo’s upside depends on converting existing merchant relationships into higher-margin services; partner changes can either help (broader distribution through TOTVS) or hinder (loss of direct control over product roadmaps).

Key takeaway: the TOTVS transaction is both a de-risking of non-core software ownership and a re-allocation of distribution power—this is a net strategic pivot that increases focus on payments but concentrates partner reliance.

Closing view for investors

StoneCo’s financial profile—notable revenue scale, strong margins, and a substantial institutional ownership base—supports a thesis of a durable payments platform shifting toward a sharper focus on merchant services. The TOTVS acquisition of Linx assets is a pivotal customer/partner event: it reduces StoneCo’s software ownership responsibilities while placing a major channel partner in control of assets that touch the merchant base. For investors, the decision point is whether the net effect increases recurring payment economics and distribution reach or whether it introduces concentrated counterparty execution risk.
