How treasury teams master multi-bank connectivity

With the proper connectivity, treasurers gain real-time visibility across all banks and entities in one place. Instead of chasing spreadsheets and portals, they can focus on optimizing liquidity and supporting important business decisions.

Why multi-bank connectivity is the missing link in modern treasury

If your treasury team is still juggling multiple bank portals, scattered ERP connections, and endless spreadsheets, you're not just wasting time—you're leaving your company exposed. A single missed cut-off or duplicate payment can lock up millions in working capital, while delayed cash visibility may force the business to borrow unnecessarily or miss an investment opportunity. Payment operations and cash visibility determine whether salaries are paid on time, suppliers are settled without delays, and the company has the liquidity to fund daily operations and strategic investments.  And yet, many treasury managers spend hours every day piecing together fragmented data instead of making decisions that move the business forward.

For mid-market multinationals, the complexity is ever-present. You may run a subsidiary in France, another in the Nordics, a shared service center in Eastern Europe, while you yourself are sitting in a mid-sized German town. Suddenly, you're managing connectivity not only across borders and jurisdictions, but also across time zones and conflicting bank cut-off times.

You might have arrived at this situation in different ways: through acquisitions that left you with multiple ERPs, by expanding into new markets with local banking partners, or by building a patchwork of systems over time. In the end, the origin doesn't matter—the reality is that complexity won't resolve itself. It will only get harder to manage until treasury takes deliberate action to centralize and regain control.. Without centralized connectivity, treasury teams can't answer the most basic questions with confidence: “How much liquidity do we actually have today?" or "Can we trust that all payments are executed correctly and on time?”

The result: sleepless nights, manual workarounds, and a constant risk of errors or fraud. Multi-bank connectivity is not a “nice-to-have.” It's the foundation for running treasury with control, confidence, and credibility.

Real-life treasury scenario: the struggles of multi-bank connectivity 

Let's step into the shoes of Maureen, a Group Treasurer at a €700M German manufacturing company. Her mandate from the CFO is clear: ensure liquidity, keep payments under control, and prevent surprises. But here's her reality:

• Seven banks across twelve countries
• Three different ERPs due to past acquisitions
• Dozens of tokens and logins for approvals

On Monday morning, she faces the same questions:

• The CFO asks: "Which accounts actually have available cash right now?”
• AP wonders: “Are Friday's vendor payments approved and executed?”
• A regional controller worries: "How do we avoid paying the same supplier twice when multiple ERPs  are in play?”

The truth? Maureen doesn't have the answers at her fingertips. Instead, she spends hours coordinating with colleagues, chasing down reports from different subsidiaries, and piecing together siloed updates over email. Even once she gathers CSV files from portals and pastes data into Excel, she's still playing catch-up—and by the time a liquidity update reaches the CFO, the numbers are already outdated.

It’s not that Maureen lacks expertise—she knows treasury inside out. The problem is that her processes are fragmented by design. And because visibility and control are scattered, she's left exposed to risks she can't fully manage:

• Missing cut-off times because one bank requires a different file format
• Duplicate payments are slipping through because two ERPs aren't synchronized
• Cash visibility that lags behind reality, forcing decisions based on yesterday's numbers

Maureen's story is fictional, but every treasury manager working in a multi-bank, multi-ERP environment will recognize themselves in it.

Key challenges of multi-bank cash and treasury management

Managing liquidity across several banks and ERPs may sound straightforward on paper. In practice, it quickly becomes a daily obstacle course. Treasury teams are expected to deliver reliable insights and oversight, yet fragmented processes often make that impossible. In an ideal world, Maureen would log into a single platform each morning, see consolidated balances across all banks and entities, and share a reliable update with the CFO in minutes. Instead, she spends hours chasing data and reconciling mismatched reports to build a partial view.

• No real-time cash visibility — balances are collected from multiple portals and spreadsheets.
• Forecasts lose credibility — by the time the CFO receives a report, the numbers are already outdated.
• Risk of misallocation — liquidity can't be deployed with confidence, and hedging strategies are based on incomplete data.

Losing working capital through unnecessary costs is another hidden risk—whether it's fraud slipping through unchecked, payments frozen due to sanctions issues, or fines piling up because cut-off times were missed and suppliers weren't paid on time.

The biggest challenges in multi-bank payment operations

Cash visibility is only one side of the equation. The other is ensuring that payments flow smoothly, securely, and on time across multiple banking partners.

Multiple banks mean multiple formats and portals

• Different file formats:

Every bank still has its own formats and processes. While industry standards have helped, they haven't removed the complexity—leaving treasury teams dependent on a solution that can harmonize these differences automatically.

• Separate portals and logins fragment approvals and oversight.
• Inconsistent workflows mean treasurers spend more time troubleshooting than managing strategy.

Manual reconciliation and compliance risks grow with scale

• Duplicate payments slip through when two ERPs trigger similar vendor runs.
• Fraud potential rises when manual uploads bypass dual controls.
• Sanctions and compliance exposure increase as files pass through different formats and systems without automated screening.

The irony? Treasurers are tasked with reducing risk, but fragmented bank processes create new ones.

The role of bank connections

Companies don't work with multiple banks by accident. They do so for:

• Risk diversification: No single bank controls all of your liquidity, protecting the company if one partner faces instability.

• Local market presence: Subsidiaries often need a domestic bank to access local clearing systems or serve regional customers.

• Currency coverage: Expanding into new markets usually requires banks that can support local currency accounts and transactions.

• Negotiation leverage: By spreading relationships, companies can compare services and fees, using competition to secure better terms.

But these benefits come with operational trade-offs.

Complexity, cost, and overhead

Every new bank adds unique formats, portals, and maintenance requirements. Instead of increasing control, it creates silos.

Why Seamless Connectivity Is Essential

Treasury needs a platform that delivers:

• Centralized access to all accounts
• Harmonized approval workflows
• Automated format conversions

Without this, the benefits of multi-banking are lost in inefficiency. With it, diversification becomes a strategic strength.

Why multiple ERPs complicate multi-bank payments and cash visibility 

Many companies also run multiple ERPs, often due to M&A or regional legacy systems. For treasury, this creates:

• Data silos — balances and forecasts are locked in separate systems
• Inconsistent formats — each ERP generates files differently
• Limited visibility — liquidity positions can't be consolidated quickly
• Approval confusion — controls vary across ERPs

Treasury's mandate is to provide accurate liquidity insights. That requires independence from ERPs — and the ability to unify data across them.

What treasury teams really need from multi-bank connectivity

Treasury's requirements can be summarized into four essentials:

• Unified access to all accounts
• Real-time cash visibility across ERPs and banks
• Automated, secure payment flows
• Integrated forecasting and reporting

Multi-bank connectivity equips treasurers with the control, confidence, and credibility they need to meet rising expectations.

How modern multi-bank connectivity solutions solve treasury challenges

Nomentia approaches these challenges by focusing on simplifying connectivity and standardizing processes without adding unnecessary complexity for treasury teams. Instead of treasurers having to manage multiple portals, formats, or integration projects themselves, Nomentia provides a central hub that connects to banks through established channels such as SWIFT, EBICS, APIs, or host-to-host links. This means that even when different banks continue to use their own standards, the complexity is absorbed by the platform rather than the finance team.

At the same time, all balances and transactions are consolidated into one view, so treasurers no longer have to chase reports across subsidiaries or stitch together spreadsheets. This real-time visibility allows them to monitor liquidity across entities, currencies, and regions in a single place. By handling user rights, audit logs, and compliance features within the same system, Nomentia also ensures that oversight and security are not compromised when operations scale.

The result is not a promise of eliminating complexity altogether, but of making it manageable. Nomentia's approach gives treasury teams practical tools to stay in control, answer CFO questions with confidence, and focus more time on decisions rather than on reconciling data.

At a Glance: Traditional vs. Modern

Transforming treasury operations: A day in the life

With Nomentia, the role of the treasurer shifts from chasing data to supervising outcomes. Instead of Maureen spending her day logging into portals, requesting reports from subsidiaries, or fixing file format errors, the platform takes care of connectivity and standardization in the background.

All balances and transactions are consolidated into a single dashboard. For Maureen, this means she no longer has to ask colleagues for updates or reconcile mismatched spreadsheets. She can monitor liquidity across entities, currencies, and regions in real time, with user rights, audit logs, and compliance checks already embedded.

With that in mind, Maureen has now re-gained the ability to focus on what matters most as a supervisor: overseeing workflows, confirming that controls are followed, and dedicating her attention to guiding strategic decisions. Nomentia ensures that her role is about managing treasury, not managing systems.

Conclusion: taking control of multi-bank payments and cash management

For treasury teams, multiple banks and ERPs are a fact of life. But fragmented processes don’t have to be.

With multi-bank connectivity, treasurers can:

• Gain real-time visibility
• Automate payments securely
• Reduce fraud and compliance risks
• Deliver trusted insights to the CFO

The bottom line: Multi-bank connectivity is the backbone of modern treasury management — enabling treasurers to move from firefighting to strategic control.
