An ERP migration can transform how a finance team operates, but the benefits depend on what happens beyond the ERP itself. As SAP S/4HANA, Oracle Fusion or Microsoft Dynamics 365 takes shape, the question of how the new system will connect to multiple banks can introduce significant complexity. IT teams may face custom integrations, individual bank specifications and projects that take six months or more to implement. It doesn’t have to work that way. For finance teams, the better question isn’t “How do we build all these connections?” It’s “Who should manage them for us?”
Why erp-to-bank integration projects often stall
Most ERP platforms are very good at what they were designed to do. Native connectivity to a complex banking estate is another matter. As AccessPay’s whitepaper, The Payments Your Systems Cannot See, explains, ERP and TMS platforms were never designed to handle the full complexity of connecting businesses to banks. Different banks can require different protocols, file formats and technical configurations.
That last mile can leave an otherwise successful ERP transformation dependent on manual file downloads, uploads and bank portal logins. The result? A new ERP sitting alongside surprisingly old banking processes.
Why connecting multiple banks shouldn’t be an it project
Building direct connections internally means more than getting them live. Somebody has to scope, test, secure and maintain each connection as bank requirements change. A managed bank connectivity service changes the model.
AccessPay acts as the integration layer between your finance applications and banking estate. Rather than asking your IT team to build and maintain individual connections, AccessPay manages that connectivity on your behalf. That frees IT to concentrate on the ERP migration itself.
It is part of a broader move towards embedded corporate banking, where banking operations are connected around the systems finance teams already use rather than remaining fragmented across individual bank portals.
How corporate-to-bank integration works
With corporate-to-bank integration, payment and financial data moves directly between your ERP and banks through a secure integration layer. AccessPay can connect finance applications via SFTP or API and manage bank connections through methods including Host-to-Host, SWIFT, EBICS and APIs. Our file transformation engine handles differences between systems and banks, helping avoid the need to change ERP output files simply because a bank expects something different.
The connection can work both ways. Payment instructions travel out to banks, while statements and status information return to finance systems, supporting payments automation and automated bank statement retrieval. For finance teams still relying on manual payment processes, AccessPay also provides practical guidance on moving from manual processing to Bacs payment automation.
Connecting SAP s/4Hana, Oracle fusion and Microsoft dynamics 365
An ERP migration is actually a good place to rethink banking connectivity, provided it happens early enough. Whether you are moving to SAP S/4HANA, Oracle Fusion or Microsoft Dynamics 365, the principle is the same: separate the ERP from the complexity of individual bank connections.
AccessPay becomes the intermediary. Your ERP communicates with AccessPay, we handle the connections and data transformation required across your banking estate. NSG Group, for example, selected SAP S/4HANA as part of its treasury transformation, with AccessPay providing the integration layer connecting SAP to its banks globally through SWIFT.
API banking integration vs traditional custom integrations
API banking integration can provide fast, automated exchange of financial data, but APIs are only one part of the connectivity picture. Not every bank, payment rail or use case operates in the same way. A multi-banked organisation may need APIs alongside Host-to-Host, SWIFT, EBICS or SFTP.
That is where a bank-agnostic integration layer becomes useful. Instead of engineering a separate solution around every banking relationship, finance can use the connectivity method appropriate to each bank while retaining a consistent process internally.
Managing multiple bank connections from a single platform
As organisations expand, the problem compounds. Another entity, country or banking partner can mean another portal, format and process. Centralising those connections gives finance one route between its back-office systems and banking estate.
It also improves bank account integration by reducing manual movement of files between systems and supporting a more consistent flow of payment and statement data. For finance directors, that means less dependence on spreadsheets and portals, and better visibility over what is happening across the banking estate.
The same principle extends across different payment types and workflows. AccessPay’s payments Knowledge Hub explores how finance teams can reduce manual intervention and build more automated, controlled payment processes.
The benefits of a managed bank integration service
The immediate benefit is less technical work for internal teams. The longer-term value goes further. Managed connectivity can:
- Reduce manual file handling and bank portal activity
- Support straight-through payment processing
- Automate statement retrieval and reconciliation workflows
- Accommodate different banking protocols and file formats
- Improve auditability and control and
- Scale as banks, entities and payment requirements change.
This matters because ERP migration is rarely the end of transformation. The infrastructure needs to cope with what comes next.
4–6 weeks vs 6+ months: comparing implementation approaches
| Traditional in-house approach | Managed Host-to-Host with AccessPay |
| 6+ months | As little as 4–6 weeks |
| Internal resources are needed to develop connectivity. | Connectivity managed by bank integration specialists. |
| Bespoke connections to build and maintain. | AccessPay manages bank connections. |
| Complexity grows with the banking estate. | Designed to support multi-bank operations. |
| IT owns much of the technical burden. | Dedicated implementation support. |
AccessPay’s Host-to-Host service can go live in as little as 4–6 weeks, rather than 6+ months. Our customer stories show how organisations have applied these principles in practice, from automating payments and bank statement retrieval to improving cash visibility across complex banking estates.
Choosing the right bank connectivity solution
Start with the banking estate, not the technology buzzword. Which banks need connecting? Which payment rails are involved? What files does the ERP produce? Do you need statements returned automatically? What happens when another bank or entity is added?
A good solution should accommodate those differences without turning each one into another development project. AccessPay supports multiple connectivity methods and payment formats, creating a managed layer between finance systems and banks. The AccessPay Connectivity Knowledge Hub has further guidance on the available approaches.
Frequently Asked Questions
Can AccessPay connect an ERP to multiple banks?
Yes. AccessPay states that there is no limit to the number of bank connections it can manage, with larger requirements scoped as phased projects.
Do we need to change our ERP files?
Not necessarily. AccessPay’s file-agnostic transformation engine can transform data between formats required by finance applications and banks.
Can connectivity include payments and statements?
Yes. AccessPay supports outgoing payment processes as well as automated retrieval of bank statements and status information.
Don’t let bank connectivity delay the ERP migration
A major ERP project already asks enough of IT and finance. Connecting that ERP to every bank doesn’t need to become another bespoke development programme. Treat bank connectivity as a managed service instead. You can preserve the investment you are making in SAP S/4HANA, Oracle Fusion or Microsoft Dynamics 365 while putting a specialist integration layer between the ERP and the complexity of your banking estate.
The ERP project stays focused on the ERP. AccessPay takes care of getting it connected. Book an AccessPay demo to discuss your ERP migration and bank connectivity requirements.
