Business Process Automation: How to Connect Software, Data and People

A new application can solve an important business problem. It can replace spreadsheets, improve customer experience, automate operational activities or give employees faster access to information.

Depending on its scope and architecture, custom software may support a focused area of the business or manage an entire end-to-end process. It can include advanced business logic, integrations, document processing, task management and automated decision paths.

In complex organisations, however, digital products often need to operate within a broader technology ecosystem. They may need to exchange information with existing ERP and CRM systems, coordinate activities across departments, manage documents and support established approval structures.

Business process automation is one of the architectural approaches that can support this coordination.

A company may use a custom application, a process automation platform or a combination of both. The right model depends on the organisation’s processes, business objectives, existing IT environment and product requirements.

What is business process automation?

Business process automation, commonly referred to as BPA, is the use of technology to execute, coordinate and monitor repeatable business processes.

A business process automation system can collect data, assign tasks, manage approvals, monitor deadlines, exchange information between applications and record the complete history of a case.

Depending on the process, it may also:

• validate information from forms or documents
• generate notifications and escalations
• create documents and reports
• transfer data to ERP or CRM systems
• initiate additional activities
• monitor service-level agreements
• archive completed cases

The objective is not to remove people from every process.

It is to automate repetitive activities while ensuring that employees remain involved whenever their knowledge, judgement or approval is required.

Companies considering business process automation should therefore look beyond individual tasks. The most valuable automation opportunities are often found where information, documents and responsibilities move between different teams or systems.

How custom software and business process automation can work together

Custom software is designed around the specific needs of a company, its users and its business model.

Depending on the project scope, it may support a single activity, automate a complete workflow or become the central system used to manage a particular area of the organisation.

It can take the form of:

• a customer portal
• a mobile application
• an IoT ecosystem
• an internal dashboard
• an order management system
• an employee self-service platform
• a specialised industry solution

Its functionality and level of automation are determined during the discovery, product design and software architecture stages.

Business process automation should not be treated as an alternative to custom software or as a way to compensate for its limitations.

In many organisations, the two approaches simply serve different purposes within the same technology ecosystem.

Custom software is often responsible for delivering tailored functionality, unique business logic and a user experience designed around specific requirements.

A business process automation platform may be introduced when the application also needs to participate in broader, cross-departmental workflows involving existing systems, documents, approval structures and organisational responsibilities.

Consider a company developing a portal through which contractors can submit documents and service requests.

Depending on the project requirements, the complete processing logic may be built directly into the custom solution. The portal can validate data, assign cases, manage statuses, generate notifications and support employees throughout the entire process.

In a more complex enterprise environment, however, the portal may also need to exchange information with an ERP system, document repository, CRM platform or other applications already used by the organisation.

Requests may follow different approval paths, involve several departments or require a complete audit trail. In this scenario, the company can choose to connect the custom application with a business process automation platform.

The custom solution remains the application through which contractors and employees interact with the service.

The process automation layer can coordinate selected back-office activities, such as:

• transferring information between existing systems
• assigning tasks according to predefined responsibilities
• monitoring deadlines and service levels
• managing multi-stage approvals
• recording decisions and process history
• returning updated information to the application

This is not a question of one technology being better or more complete than the other.

It is an architectural decision based on the scope of the product, the existing IT environment and the complexity of the organisation’s processes.

When properly integrated, custom software and process automation can create a modular environment in which each component performs a clearly defined role.

BPA, workflow automation and RPA: what is the difference?

Business process automation, workflow automation and robotic process automation are closely related, but they do not mean exactly the same thing.

Workflow automation

Workflow automation manages how tasks, information and decisions move between people or systems.

For example, a purchase request may be sent first to a manager, then to the finance department and finally to procurement.

The workflow defines:

• who receives the request
• which approvals are required
• what happens when information is missing
• how the process continues after each decision

Robotic process automation

Robotic process automation, or RPA, automates repetitive actions that a person would normally perform through a software interface.

A software robot may:

• copy data between applications
• download reports
• create records in another system
• enter information into a legacy application
• complete recurring administrative activities

RPA is particularly useful when a system does not provide a suitable API or another modern integration mechanism.

Business process automation

Business process automation has a broader scope.

It coordinates the complete process and may combine:

• workflow management
• system integrations
• business rules
• document processing
• RPA
• artificial intelligence

Workflow automation controls the flow of tasks. RPA performs selected repetitive actions. BPA coordinates these and other technologies within an end-to-end process.

What does an effective automation environment include?

A scalable process automation environment should connect several elements that often operate separately within an organisation.

Process logic

Every automated process needs a clearly defined structure.

The organisation should establish:

• what initiates the process
• which stages it includes
• who is responsible for each activity
• which decisions are required
• what happens when information is missing
• how exceptions are handled
• when a deadline or escalation should be triggered

Low-code process modelling can make this logic easier to understand and modify.

Business and IT teams can work with the same visual process model instead of translating requirements between operational descriptions and technical documentation.

System integrations

Most companies already use several business applications.

A process automation initiative does not necessarily require the organisation to replace these systems. Instead, an automation platform can connect selected elements of the existing environment.

It may exchange information with:

• ERP systems
• CRM platforms
• Microsoft 365
• SharePoint
• accounting applications
• databases
• external portals
• custom-built software

Depending on the available technology, integrations may use APIs, database connections, dedicated connectors or RPA.

The purpose is to allow relevant information to move through the process without employees repeatedly copying it between systems.

Data and document processing

Business processes involve more than structured database records.

They also include:

• invoices
• contracts
• forms
• emails
• attachments
• applications
• scanned documents

OCR and intelligent document recognition can extract relevant information, classify documents and initiate the appropriate workflow.

For example, an invoice process may automatically identify:

• the supplier
• invoice number
• total amount
• payment date
• purchase order reference

The extracted data can then be checked against information stored in another system before the invoice is sent for approval.

Business rules and decisions

Some decisions can be automated using predefined rules.

For example:

• a request below a specified value may follow a simplified approval path
• an incomplete application may be returned to the sender
• an invoice without a purchase order may require additional verification
• a case approaching its deadline may be escalated

More complex processes may also use AI to analyse content, summarise information or recommend the next action.

The level of automation should always reflect the risk of the decision.

Financial, legal or employment-related decisions may still require human approval, even when AI prepares and organises the necessary information.

Monitoring and auditability

Automation should improve process visibility.

Employees and managers should be able to check:

• the current status of a case
• who is responsible for the next task
• which deadlines are at risk
• what decisions have been made
• which data or documents were used
• how long individual stages took

A complete audit trail is particularly important in regulated industries and processes involving sensitive, contractual or financial information.

Which business processes can be automated?

The best candidates are usually repeatable processes involving multiple steps, systems, documents or participants.

Invoice processing

Invoices can be collected from email, electronic platforms or other sources.

Relevant data can be extracted, verified and sent through the appropriate approval path. After approval, the information can be transferred to the accounting or ERP system.

The document can then be archived together with its complete processing history.

Employee onboarding

Employee onboarding requires coordination between HR, IT, administration, payroll and the employee’s manager.

An automated workflow can:

• generate task lists
• collect employee documents
• request equipment
• initiate account creation
• assign responsibilities
• monitor whether every required activity is completed before the employee’s first day

Contract management

A contract process may include:

• submitting a contract request
• selecting an appropriate template
• preparing the document
• legal review
• negotiation
• approval
• signature
• archiving
• monitoring renewal or termination dates

Automation helps employees understand the current status of the contract and prevents important documents or deadlines from remaining unnoticed in email inboxes.

Purchase requests

Employees can submit structured purchase requests that are routed according to their value, category, department or budget.

The process may include:

• managerial approval
• budget verification
• procurement activities
• order creation
• final confirmation

Customer and contractor service

A portal or mobile application can support submission, validation, case assignment, status updates and other operational activities.

Depending on the architecture, these capabilities may be implemented directly within the custom solution, managed by a process automation platform or distributed between both components.

For example, a custom portal may manage the user-facing experience and product-specific functionality, while a connected workflow coordinates activities involving internal departments, documents and existing business systems.

The most appropriate model depends on the application’s scope, the existing IT environment and the number of systems and departments involved.

How to start business process automation

Effective automation does not begin with selecting as many processes as possible. It begins with understanding one process well enough to improve it.

1. Select and map the process

A good first process should be important enough to produce a measurable result but manageable enough to implement and evaluate.

Strong candidates usually involve:

• frequent manual data entry
• multiple approval stages
• long waiting times
• recurring errors
• limited visibility
• information distributed across emails and spreadsheets

The organisation should document what actually happens, including exceptions and informal workarounds, rather than relying only on the official procedure.

Employees who perform the process every day should be involved in this analysis. They usually know where delays, duplicated work and inconsistencies occur.

2. Define the objective

Automation should have a clear business purpose.

The objective may be to:

• reduce processing time
• eliminate repetitive data entry
• improve compliance
• shorten response times
• reduce errors
• increase process visibility
• make the process easier to scale

The organisation should define how the expected result will be measured before implementation begins.

3. Design the target workflow and integrations

The new process should not simply recreate every historical activity in digital form.

Some steps may no longer be necessary. Others can be combined, standardised or automated.

The target workflow should define:

• what happens automatically
• where employees make decisions
• how exceptions are handled
• which systems exchange information
• what data needs to be recorded
• which actions require human approval

Integrations should follow the operational process.

The main question is not only which systems can be connected, but which information must move between them for the process to work efficiently.

4. Launch a pilot and improve it

A pilot makes it possible to test the workflow with real users and real cases.

Feedback from employees, process owners and IT teams can then be used to improve:

• forms
• rules
• notifications
• integrations
• responsibilities
• exception handling

Low-code platforms support this iterative approach because workflows can be modified as requirements evolve.

Choosing the right automation architecture

There is no single architecture that works for every organisation.

A complete process may be implemented as custom software, configured within a process automation platform or supported through a combination of both approaches.

When custom development may be the right choice

Custom development may be appropriate when the organisation requires:

• highly specialised functionality
• unique business logic
• a tailored user experience
• a digital product that forms part of the company’s competitive advantage
• an architecture designed around specific performance and scalability requirements

Custom software can support both user-facing features and complete operational workflows.

When a process automation platform may be useful

A process automation platform may be useful when the organisation needs:

• reusable workflow capabilities
• centralised task management
• configurable approval paths
• audit trails
• document handling
• low-code process modelling
• integrations spanning several departments and existing systems

Platforms can allow organisations to introduce and modify workflows without developing every standard process component from the beginning.

When a hybrid architecture may be appropriate

In a hybrid architecture, custom applications and automation platforms perform clearly defined roles.

A custom application may provide specialised functionality and user-facing services, while an automation platform coordinates selected cross-system or cross-departmental processes.

However, this model is one option rather than a universal requirement.

The decision should be based on:

• the organisation’s business objectives
• the required user experience
• existing systems
• process complexity
• maintenance expectations
• long-term development plans

Platforms such as JobRouter®, implemented by e-MSI, support organisations that choose a platform-based or hybrid approach by combining low-code process modelling with document management, integrations and automation capabilities.

Common process automation mistakes

One of the most common mistakes is automating a process before understanding why it is inefficient.

Automation can make an activity faster, but it does not automatically make it better.

Unnecessary approvals, duplicated tasks and unclear responsibilities may remain after implementation.

Another mistake is analysing individual system features without considering how the complete process operates across users, departments and applications.

A well-designed interface is important, but so are:

• data flows
• responsibilities
• integrations
• exceptions
• security
• decision paths

These elements may be implemented within one custom solution or distributed across several connected systems.

Companies should also plan for exceptions. Real processes rarely follow one ideal path.

Missing information, unusual requests, rejected approvals and system errors need to be included in the workflow design.

Finally, success should be measured through business outcomes rather than technical delivery alone.

Launching the workflow is not the final objective.

The organisation should track:

• processing time
• error rates
• workload
• deadline compliance
• user satisfaction
• process transparency

How AI supports business process automation

Traditional automation follows predefined rules.

AI expands these capabilities by helping systems work with unstructured information and more complex content.

AI can support a business process by:

• recognising and classifying documents
• extracting information from text
• summarising correspondence
• detecting inconsistencies
• recommending the next action
• creating draft responses
• preparing documents

More advanced AI agents may perform selected activities within the workflow using authorised process data and tools.

However, effective intelligent automation requires clear process governance.

The organisation should define:

• what an AI agent can access
• which actions it may perform
• which decisions require human approval
• how exceptions should be handled
• how the agent’s activity is recorded

AI should become a controlled component of the process rather than a separate experiment operating outside the organisation’s workflow and permission structure.

Final thoughts

Custom software and business process automation address different architectural and operational needs.

Either approach may support a complete process, depending on the scope of the solution and the environment in which it operates.

Custom applications are particularly valuable when an organisation needs specialised functionality, unique business logic or a tailored user experience.

Process automation platforms can support situations in which workflows extend across multiple systems, departments, documents and approval structures.

In some projects, one approach will be sufficient.

In others, combining both technologies can create a modular environment in which data moves efficiently, responsibilities remain clear and decisions are visible and auditable.

The key question is not which technology is universally better. It is which architecture best reflects the organisation’s processes, users, business objectives and existing IT ecosystem.

Frequently asked questions

What is business process automation?

Business process automation uses technology to coordinate repeatable tasks, decisions, data and documents.

It can reduce manual work, improve process visibility and ensure that cases follow clearly defined rules and responsibilities.

Is business process automation the same as RPA?

No.

RPA automates individual repetitive actions, such as copying data between systems or entering information into an application.

Business process automation coordinates a broader process and may use RPA as one of its components.

Can custom software automate an entire business process?

Yes.

Custom software can be designed to support an individual activity or a complete end-to-end process. Its scope depends on the organisation’s requirements, software architecture and product strategy.

Can business process automation support custom applications?

Yes.

Business process automation platforms can be integrated with custom web and mobile applications when a process needs to extend across other systems, documents, departments or approval structures.

Depending on the project architecture, process logic may be implemented within the custom application, the automation platform or both.

Does a company need to replace its existing systems to introduce BPA?

Not necessarily.

A process automation platform can be integrated with existing ERP, CRM, accounting, document management and custom systems through APIs, connectors, database connections or RPA.

Which process should be automated first?

A good first candidate is a repeatable process with a clearly defined problem and measurable objective.

Examples include processes involving manual data entry, long approval times, recurring errors, unclear responsibilities or limited status visibility.

Can AI make decisions within an automated process?

AI can analyse information, recommend actions and perform authorised activities.

The organisation should define clear permission boundaries and retain human approval where decisions involve significant financial, legal, employment-related or operational risk.
