How do ERP integrations work?

What is ERP integration?

ERP Integrations connect your ERP software to other platforms to automate data flow. This means that your information will stay consistent across all the different platforms you use.

For example, when a customer places an order on your online store, an integrated ERP will automatically update your stock levels, push order details to your finance module and start the fulfillment process. These updates happen according to the integration’s configuration and schedule.

Without effective ERP integrations, teams often get stuck using spreadsheets and manually uploading files. For example, teams may have to download an Excel file, update it to fit another platform’s template, and upload it there. This could cause delays to orders due to inaccurate stock levels, and your finance team will have to spend hours matching records.

How do ERP integrations work?

ERP integrations use secure connections to share data between systems.

• API-based integrations: APIs let systems like your CRM, e-commerce platform, and payment platform talk to each other directly, so that inventory, orders, and payment status stay up to date. Updates can occur as they happen or on a schedule, depending on how the integration is configured.

• Middleware and iPaaS solutions: Middleware and integration platform as a service (iPaaS) tools send data to the right place, convert it into the right format, and deal with any errors along the way.

• File-based integrations: Systems exchange files containing records like invoices or payment details. You can set file transfers to run on a schedule, and you can add checks to catch missing data or formatting issues.

• Cloud and on-premises systems: These integration methods can connect cloud-based or on-premises systems. Integrating cloud-based systems can help reduce the amount of infrastructure a business has to manage. Whereas integrating on-prem systems gives you more control over the infrastructure but may require more internal IT support. You can also take a hybrid approach to integrating on-prem systems with cloud-based applications.

Whichever approach you choose, every integration should have encryption and access controls in place.

How does ERP integration support automation?

ERP integration helps automate processes by moving data between systems without someone having to manually transfer it. That transfer can then trigger the next step in a workflow. For example, once an invoice has been approved, it can be sent from your accounts payable (AP) software to your ERP for payment processing.

Depending on what you are trying to do, you can use a combination of ERP integrations with:

• Workflow rules: Route approvals or send reminders based on certain conditions.

• AI-assisted tasks: Extract invoice data, spot anomalies, or even predict when payments will be made, with people reviewing exceptions.

• Robotic process automation (RPA): Perform repetitive tasks through an application’s interface using software bots (when direct integration is not possible).

How do manual and automated ERP workflows compare?

Automation changes how everyday ERP tasks like entering data and routing approvals are completed. The table below compares common manual steps with automated alternatives.

Which systems can integrate with an ERP?

ERP systems rarely work alone. Businesses integrate them with other software to coordinate work across departments and keep data consistent across teams.

Common ERP integrations include:

Which business processes can ERP integrations automate?

ERP integrations can reduce manual data transfers and delays across several business processes, such as:

• Manufacturing and inventory: Warehouse activity updates inventory records in the ERP. Configured replenishment rules can trigger purchase requests when stock falls below a set level.

• Retail and order fulfillment: Online stores, ERP systems, and warehouse software share order and shipping details automatically, reducing the need for manual entry.

• Accounts payable and receivable: AP software can capture invoices, route invoices for approval, and transfer approved records to the ERP. Connected AR software uses invoice and payment data to support collections. Learn more about how AP automation works with your ERP and how AR automation works.

• Reporting across departments: Business intelligence tools combine ERP, sales, and operational data, helping managers review performance without having to manually combine separate exports.

How can ERP automation improve efficiency and reporting accuracy?

• Less repetitive work: Automatic data transfers, approval routing, and reminders reduce data entry and follow-up.

• More reliable reporting: Consistent data mapping and validation checks help reduce discrepancies between systems. Accuracy still depends on correct source data.

• Lower processing costs: Less manual work often reduces the cost per transaction. Compare these savings with implementation, software, and ongoing support costs.

• Support for growth: Repeatable workflows help teams manage higher transaction volumes and additional business units, with rules and permissions adjusted as needed.

For example, businesses using Quadient AP with Sage Intacct can reduce data entry by up to 83% with automated invoice capture.

How do you measure the results of ERP integration?

Compare the workflow before and after integration to see whether it saves time and reduces errors. Record a starting point before the pilot, then measure the same activities once the connection is running.

Useful measures include:

• Processing time: How long does a transaction take from start to finish, including approvals?

• Manual steps: How often does someone need to enter, check, or correct information?

• Transfer failures: How many records fail to reach the receiving system?

• Reporting differences: How often do teams find mismatched records between systems?

• Cost per transaction: What does processing cost, including software and support?

Compare similar transaction volumes and include time spent fixing errors. A faster transfer provides little benefit if employees spend the saved time correcting records.

What are the potential challenges of ERP integration?

• Inconsistent or incorrect data: Duplicate supplier records or incompatible account structures can disrupt transfers. Clean up records and agree on how updates will be managed.

• Unclear responsibilities: Define which system owns each record and who handles exceptions and approves changes.

• Failed or repeated transfers: Check how the integration detects duplicates, retries failed transfers, and alerts the team.

• Access and maintenance: Set appropriate permissions, review access when roles change, and assign responsibility for support and testing after upgrades.

What happens when an ERP data transfer fails?

When a transfer fails, the team responsible needs to identify the cause, correct the problem, and confirm that the record reaches the receiving system. Depending on the setup, an integration may retry automatically or flag the record for review.

For example, an approved invoice might fail to transfer because its supplier identifier does not match a supplier record in the ERP. The person responsible would check the supplier details, correct the record or mapping, and retry the transfer.

Before retrying, check whether any part of the transaction was already processed to avoid creating a duplicate. Afterward, confirm that the invoice details match in both systems. Keep a record of the error and correction so recurring problems can be identified and addressed.

How do you implement ERP integrations and automated workflows?

1. Identify goals and problems: Define what you want to improve, such as a faster month-end close, fewer manual entries, or better visibility into operations. Clear goals guide the tool you select and how you measure success.

2. Map data flows and choose integration tools: Determine which systems need to connect and what data must flow between them. Choose an integration method based on complexity, scale, and internal resources.

3. Test, train, and maintain: Start with one workflow. Test normal transactions and failures, check access controls, and compare records in both systems before expanding. Train users on the new workflows, then monitor performance and refine processes as business needs change.

How do you choose the right ERP integration and automation tools?

Choosing the right integration approach depends on the systems you use and your priorities. Review what your existing ERP can do, then compare tools based on your business requirements.

Ask providers:

• Will the integration work with our ERP system and the data we will be moving?

• What data moves between systems, and how often?

• How are approvals and failed transfers handled?

• Who maintains the connection, and what does support cost?

• Can we test it with our own transactions before committing?

Ask providers to demo the connection using typical examples of how you will use the solution in practice. Include custom fields, different approval rules, and additional business units if relevant. A demo using only a basic invoice may not show whether the integration meets your needs.

Include an exception, such as a missing supplier identifier, and ask the provider to show how your team would find and resolve it. Confirm which features are included in the quoted price and which need extra configuration or development.

Also, agree on who supports the connection after launch. Your team should know whom to contact when data stops moving, or a software update changes the workflow.
