When BPM and ERP are used together, corporate records and the task and approval steps around them become part of the same operation. ERP manages the data of operations such as finance, inventory, procurement and production. BPM is the approach of designing, running and improving the steps a piece of work goes through, who is responsible for them and which rules apply.
When evaluating these two, you should first look at which needs your existing ERP already meets. ERP products can also offer workflow and automation features. The value of an additional BPM platform shows up in processes that span different applications, change often or require special approval rules.
Key differences between BPM and ERP
- ERP's focus: Consistent management of operational records such as orders, inventory, accounts and bookkeeping.
- BPM's focus: Managing the tasks, decisions, documents and owners of a piece of work together, from start to completion.
- Common ground: Both can contribute to automation. The distinction should not be framed as “one can do it, the other can't”; it should be assessed in terms of existing product scope, process needs and integration.
For example, while a purchase order is created in the ERP, the preceding request, budget check, quote evaluation and authorized approval may run in different applications. PaperWork process automation can be used to bring these tasks together in a shared flow.
When should an organization using ERP consider BPM?
You do not need to add a separate BPM application to every ERP project. First identify where work gets stuck. If employees are re-entering the same information, approvals are getting lost in email or different departments cannot see the status of a process, the current setup may be worth reconsidering.
Frequently changing authorization limits, organization-specific forms, work involving external stakeholders and processes that span multiple systems are also topics to evaluate. The decision should not be based only on the number of features on screen; you should also discuss who will maintain the process, and how, when it changes.
Where can BPM complement ERP?
Data collection and approval workflows
The requester enters information through a mobile or web form. Mandatory fields and business rules are checked, and tasks are assigned to the relevant people. This makes it possible to track the approvals and checks required before a record is transferred to the ERP.
Data and document links between applications
A process can read supplier or inventory information from the ERP and send the approved result back to the relevant system. Documents can also be linked to the transaction record. PaperWork's ERP and enterprise application integration page explains ready-made connectors and custom connection methods.
Process visibility and measurement
You can track who a piece of work is waiting on, at which step it is delayed and how long it took to complete. Process analytics helps you evaluate not just the number of completed transactions but also waiting times and improvement needs.
Example: From purchase request to ERP order
The procurement process is an example of BPM and ERP working together.
- The employee creates a purchase request with the item, quantity, justification and attachments.
- The required inventory, supplier or budget information is retrieved from the ERP.
- The request goes for approval according to the organization's amount and department rules.
- If information is missing or a condition is not met, the record is returned to the relevant person.
- When approval is complete, the required data is transferred to the order transaction in the ERP.
- The transfer result and document links are recorded; if a transaction fails, it is made visible to the owner.
The same approach can be applied to areas such as expense approval, supplier onboarding, contracts or customer requests. For each process, the owner of the records and the responsibilities between applications should be defined separately.
What to clarify before integration
- Master data source: Which system will supplier, customer and inventory information come from?
- Field mapping: Do codes, date and amount formats mean the same thing in both systems?
- Error handling: If the ERP cannot be reached, where will the transaction wait and how will it be retried?
- Duplicate record control: If the same approval or transfer runs more than once, how will duplicate records be prevented?
- Authorization: Are the actions that users and the integration account can perform restricted?
- Change management: What tests will be run when a form, process or ERP version changes?
Organizations using SAP can also assess the connection scope through PaperWork SAP connectors. Having a ready-made connector does not mean all business rules are automatically covered.
What criteria should you use when choosing a BPM solution?
Choosing a BPM solution starts with defining the organization's process needs. In selection meetings, check the following using a concrete process:
- Whether business units can use the form and task screens.
- Compatibility with your existing ERP, document management and user infrastructure.
- Whether the setup stays manageable as the number of transactions and users grows.
- Whether roles, access and activity logs meet your needs.
- Whether waiting times and process outcomes can be reported.
- Whether training, documentation, support and maintenance responsibilities after go-live are clear.
Low-code development tools help build forms and applications. However, they do not eliminate the need for analysis, authorization, integration and testing. During the demo, use normal and exceptional cases from your own process instead of just watching a ready-made screen.
How do you measure success?
Before the pilot, record the current completion time, manual data entry, number of returned requests and time users spend. After the pilot, repeat the same measurements for similar transaction types. Gains depend on process complexity, data quality, integrations and user adoption of the system.
Frequently asked questions
Does BPM replace ERP?
In this scenario the goal is not to remove the ERP. It is to run the records managed by the ERP together with the task and approval steps in different systems.
If the ERP has workflow, do you still need BPM?
Not always. You should assess whether the existing workflow meets your needs, whether it covers different applications and how changes are managed.
Where should an integration project start?
Choose a process with clear boundaries and map out the data sources, owners, approvals and error scenarios. Then decide on the connection method and the pilot's acceptance criteria.
