Accounts Payable (AP) software vendors face the critical challenge of integrating seamlessly with various Enterprise Resource Planning (ERP) systems. Why it is that important for the customer of AP software is obvious:
Automated synchronised data eliminates manual reconciliation in the ERP and accelerating financial close by over 25%.
However, traditional integration methods often involve complex and time-consuming software development and implementation, that hinder scalability and responsiveness. Our Unified API offer a transformative solution to these challenges, enabling Accounts Payable software vendors to accelerate ERP integrations and deliver enhanced value with numerous out-of-the box integrations to their clients.
Especially for Accounts Payable use cases, the business complexity is vast. Take control of supplier management, Procurement, invoice management, payment scheduling, card spend, and supplier correspondence, with real-time multi-entity reconciliation of payment details with invoices, billing, purchase order matching and approval processes.
The Complexity of Traditional ERP Integrations
Integrating AP software with multiple ERP systems traditionally requires developing custom connectors for each platform. This approach presents several challenges:
Resource Intensive: Developing and maintaining individual integrations demands significant time and technical expertise, diverting resources from core product development.
Scalability Issues: As the number of ERP systems grows, the complexity and cost of maintaining numerous integrations escalate, making it difficult to scale efficiently.
Inconsistent Data Handling: Variations in data formats and structures across different ERPs can lead to inconsistencies, increasing the risk of errors and complicating data reconciliation.
What often starts as a straightforward project quickly turns into a resource-intensive effort. Beyond the initial development, maintaining these integrations demands continuous updates, troubleshooting, and adapting to ERP system changes. The real cost isn’t just the upfront investment—it’s the long-term commitment to ongoing maintenance, which can quietly consume tens of thousands of euros annually.
Additionally, there’s an often-overlooked opportunity cost: every hour spent on integration work is time taken away from refining your product, launching new features, or addressing customer needs. In fast-moving Software environments, this delay can hinder innovation and slow down growth.
Unified APIs: A Streamlined Approach to ERP Integration
Maesn’s Unified API provide a standardized interface that allows AP software vendors to connect with multiple ERP systems through a single integration point. This approach offers several key advantages:
Simplified Integration Process: By interacting with our Unified API, vendors can avoid the intricacies of individual ERP, reducing development time and complexity.
· Shortcut Partnering: Immediate access to sandboxes and required infrastructure.
Enhanced Scalability: A single integration enables connectivity to various ERP systems, allowing vendors to expand their offerings without proportional increases in integration efforts.
Consistent Data Management: Unified APIs standardize data formats, ensuring consistent data handling across different platforms and improving data accuracy.
Practical Implementation: Synchronizing AP Software with ERP Systems
Implementing a Unified API for ERP integrations involves several key workflows, that needs be enabled for a comprehensive integration between the AP software and ERP Software:
Initial Mapping:
Objective: Establish a one-time mapping between AP software objects and corresponding ERP entities.
Process: Enable mapping of various objects in the AP software to the ERP system, aligning data fields and structures.
Maesn Unified API Endpoints:
GET companies, GET accountsInitial Synchronization:
Objective: Perform a comprehensive data sync to ensure both systems are aligned.
Process: Synchronize e.g. payment terms, general ledger (GL) accounts, custom dimensions, taxes, units and payees (suppliers) from the ERP to the AP software.
Maesn Unified API Endpoints:
GET paymentterms, GET accounts, GET dimensions, GET suppliersOngoing Synchronization from ERP to AP Software:
Objective: Maintain data consistency by continuously updating the AP software with changes from the ERP system.
Process: Reflect additions, updates, or deletions of objects as well as purchase orders and good received receipts in the ERP within the AP software.
Maesn Unified API Endpoints:
GET paymentTerms, GET accounts, GET dimensions
Ongoing Synchronization from AP Software to ERP:
Objective: Ensure the ERP system remains updated with the latest data from the AP software.
Process: Continuously synchronize payees/suppliers, bills, vendor credits, and payments from the AP software to the ERP.
