Accounting automation was supposed to eliminate manual work. And it did. Companies now automatically extract document data, match information and approve documents through predefined workflows.

But as the number of automations increased, a new reality emerged:

Rules had to be configured, adjusted and continuously maintained. The more automated workflows a company used, the more time it began spending managing them.

In the worst case, rules were never updated at all, and the system continued operating according to settings created on day one. Much of the potential of the accounting platform therefore remained unused.

Automation solved document processing.

The automation rules themselves, however, still had to be created manually.

This is exactly the layer that Wflow is now taking further with AI Accounting Suggestions.

The Biggest Problem With Today’s Automation? It Cannot Learn.

Modern accounting workflows are built around recurring patterns.

The same supplier. The same cost centre. The same account. The same type of approval.

Accounting teams apply these rules hundreds of times every month. Systems have been able to automate them, but the logic behind the automation has remained static and dependent on human input.

For a long time, that worked well.

But as companies grew and workflows multiplied, rule management became a surprisingly demanding part of accounting operations.

“The paradox of modern automation is that the more companies automate, the more time they begin spending managing the automations themselves. Automation removed manual document processing. But the rules still had to be created manually. And that is exactly what we wanted to change.”‍

— Robert Soudný, Co-founder and CEO of Wflow

Wflow Now Automates the Setup of Automation Itself

The new AI feature in Wflow analyses the historical behaviour of the accounting team and identifies recurring patterns in accounting decisions.

It monitors:

• how particular suppliers are accounted for,
• which workflows are repeated,
• which accounts and cost centres accountants use,
• and which suggestions they frequently correct or confirm.

Based on this behaviour, the system suggests rules that are ready to use.

The accountant can then accept them in just a few clicks — or reject them.

The important change is not that AI is “doing the accounting instead of people”.

It is that accountants no longer have to keep teaching the system the same things over and over again.

AI proactively suggests rules itself, often including patterns that users may not have thought of creating manually.

As of June 2026, the feature is available for:

• Updating accounting at document-header level
• Changing the document description

Automation Is Useful Only Until It Starts Slowing Itself Down

Most companies know this situation very well.

A workflow works perfectly. Then the supplier changes, the invoice structure changes or the approval process evolves — and the automation no longer reflects reality.

The result?

Manual corrections. New exceptions. More rule maintenance.

This is exactly where AI-assisted automation makes a fundamental difference.

AI Accounting Suggestions in Wflow continuously monitor new accounting behaviour and suggest changes based on reality, rather than on historically forgotten settings.

Automation therefore no longer starts becoming outdated the moment it is created.

Accounting Firms Do Not Lack Clients. They Lack Capacity.

For accounting firms in particular, this new layer of AI automation can represent a major change.

Every new client means:

• new workflows,
• new exceptions,
• new suppliers,
• new rule configuration.

And today, onboarding and workflow management often limit growth more than the accounting work itself.

AI Accounting Suggestions help significantly accelerate onboarding and reduce the amount of manual configuration required.

This makes it possible to process far more documents without proportionally increasing manual work.

The result?

More clients without additional hiring.

And in today’s accounting market, that is becoming a major competitive advantage.

“Digitalisation in accounting firms is not only about technology. It is primarily about changing the way people think and work. A properly configured process can save tens of percent of working time and give accountants more space to deliver real added value to clients.”

— Tomáš Kratochvíl, Key Account Manager at Wflow

Internal Finance Teams Do Not Need More People. They Need Less Routine.

Internal accounting teams are operating under increasing pressure.

Document volumes are growing. Workflows are multiplying. Expectations around speed and control are higher than ever.

And yet a large part of their time is still consumed by repetitive micro-tasks.

AI Accounting Suggestions help significantly reduce this routine.

The accounting team no longer needs to spend as much time managing rules, correcting workflows or repeatedly configuring the same logic.

Instead, it works with suggestions based on the company’s real accounting behaviour.

AI Does Not Replace Accountants. It Replaces Unnecessary Repetition.

There are plenty of expectations — and concerns — surrounding AI in accounting today.

So one thing needs to be made clear:

AI Accounting Suggestions in Wflow do not replace accounting control or responsibility.

“AI will not replace accountants. Accountants using AI will replace accountants who do not,” says Robert Soudný, Co-founder and CEO of Wflow.

AI suggests, recommends, identifies patterns and learns from historical behaviour.

And that is important.

Because the purpose of AI in accounting is not to eliminate human judgement.

It is to eliminate the routine that unnecessarily consumes human judgement.

Accounting Automation Is Entering Its Next Phase

Wflow, a EU-based platform for accounting digitalisation and automation, has long automated document processing.

Now it is automating the configuration of automation itself.

AI Accounting Suggestions help transfer accounting know-how from accountants’ heads into a system that can recognise a pattern, suggest the creation of a rule and continuously learn from real operations.

The result is not simply fewer clicks.

The result is automation that finally stops creating additional manual work.

What Is Invoice Automation?

Definition and Core Technology

Invoice automation means using software to process incoming and outgoing invoices automatically—from receiving the document and extracting its data to approval and posting.

The objective is to eliminate manual data entry and connect the individual stages of invoice processing into one controlled digital workflow.

How Automated Invoice Processing Works

Invoice automation software typically uses:

1. OCR (optical character recognition) to read invoices and accounting documents.
2. AI (artificial intelligence) to extract and automatically validate invoice data.

The system identifies key information, compares it with purchase orders and prepares the document for approval.

Automated Invoice Processing vs. Manual Processing

Benefits of Invoice Automation Software

Elimination of Manual Data Entry

Automated invoice processing significantly reduces the volume of manual work and data entry. This also lowers the administrative costs of finance and accounting teams.

Fewer Errors and Fraudulent Invoices

Automated data validation and approval workflows minimise the risk of errors, duplicate invoices and fraudulent documents.

Faster Payments and Better Cash Flow

Automation makes it possible to approve invoices within minutes. This shortens payment cycles and improves relationships with suppliers.

Better Visibility and Real-Time Reporting

Finance teams can see the status of every invoice in real time, making expense planning and financial control significantly easier.

Key Features of Modern Invoice Automation Software

AI-Powered Invoice Data Extraction

Modern software can automatically recognise and extract information from different invoice and document formats without requiring manual data entry.

Three-Way Matching

An accounting digitalisation platform such as Wflow automatically compares data from the invoice, purchase order and goods receipt.

When the system identifies a discrepancy, it flags it immediately for review.

Automated Approval Workflows

Flexible approval rules and notifications can be configured for different roles and responsibilities. Invoices can be approved in real time, including through a mobile application.

ERP and Accounting Software Integration

Integration with accounting software, ERP platforms and other business systems eliminates repeated data entry and reduces the risk of errors.

Companies can modernise invoice processing without replacing the accounting or ERP systems they already use.

Exception Alerts and Notifications

Reliable invoice automation software automatically alerts users to errors, discrepancies and missing information.

How to Get Started With Automated Invoice Extraction and Processing

Assess Invoice Volume and Process Weaknesses

Map your current process:

• How many invoices pass through your company each month?
• Where do the biggest approval delays occur?
• At which stage do errors most often appear?

Understanding the current workflow helps identify where automation can create the greatest value.

Choose the Right Platform

Compare available solutions based on:

• features,
• integrations,
• implementation requirements,
• and vendor support.

The right platform should fit your existing finance environment rather than force the company to rebuild it.

Configure Workflows and Rules

Define approval processes and set automation rules according to your organisation’s structure.

This may include:

• approval limits,
• role-based permissions,
• escalation rules,
• cost centres,
• and specific workflows for different document types.

Train Teams and Suppliers

Explain the new process clearly to internal users and external partners.

Successful implementation depends not only on the software itself, but also on whether people understand how documents should enter and move through the new workflow.

Measure the Benefits

Regularly evaluate:

• time savings,
• faster approvals,
• fewer errors,
• and shorter payment cycles.

Process configuration is largely a one-time investment, while the efficiency gains continue to grow over time.

How Automated Invoice Processing Works in Different Types of Businesses

Solutions for Small and Medium-Sized Businesses

Companies with fewer employees usually prefer tools that are easy to implement and affordable in terms of both time and cost.

A key requirement is integration with the accounting or ERP system the company already uses.

This allows SMEs to automate invoice processing without replacing a familiar and proven financial system.

Enterprise Solutions

More complex organisations require advanced workflows and greater process customisation.

Automated invoice processing can save dozens of hours each month and provide full control over financial operations.

Processes become faster, while finance teams can focus on more complex tasks that directly contribute to a financially healthier company.

Industry-Specific Requirements

Retail, manufacturing, professional services and accounting firms all have different requirements for:

• approvals,
• reporting,
• integrations,
• and document handling.

Wflow is used by companies across all of these industries.

Common Obstacles to Efficient Finance Workflows

Inconsistent Invoice Formats

Working with different invoice and document formats takes time—and sometimes strong glasses.

Modern OCR technology can process different templates and non-standard documents without difficulty.

Delayed Supplier Payments

A heavy workload in the accounting team often leads to payment delays.

Invoice automation software helps prevent these delays by moving documents through validation and approval more efficiently.

It is worth communicating the benefits of automation to suppliers as well.

Faster payments and fewer errors can become a competitive advantage in supplier relationships.

Integration With Legacy Systems

Look for a solution with an open API and proven experience in system integration and data migration.

Wflow integrates with a wide range of established accounting and ERP systems, helping companies introduce a new workflow without unnecessary disruption.

‍Where will e-invoices arrive? Who will check them? How will they connect to the ERP? And what happens to invoices that do not match?

Most importantly: Who will reassure the accounting team that “it will be simple” while one of the company’s most sensitive processes is changing?

This is where the difference emerges between a company that introduces e-invoicing as another isolated project and one that already has its invoices under control through an accounting digitalisation and automation platform.

When documents already pass through a digital workflow, with clearly defined approvals, an audit trail, ERP integration and predefined rules, e-invoicing is not a revolution. It is simply a new type of input into an existing process.

Wflow helps companies prepare their accounting processes so that e-invoicing does not create chaos, but instead delivers cleaner data, less manual work and faster processing.

The First Step Towards E-Invoicing: A Workflow That Works

E-invoicing will become a problem in companies where nobody currently knows exactly what happens to an invoice between receipt and posting.

When invoices arrive through different channels, are approved by email, exceptions are resolved over the phone and the ERP is only the final destination of the document, e-invoicing alone will not solve the problem.

It will simply provide a more structured input into a process that was already out of control.

That is why some companies see e-invoicing as a threat.

What Changes When a Company Uses Wflow

In Wflow, every document has its place from the very beginning. It passes through an approval workflow, has clearly assigned responsible people, accounting context, a complete change history and a connection to the ERP.

When the way an invoice enters the company changes, the entire subsequent process does not need to be rebuilt.

That is the key point.

E-invoicing itself primarily ensures that an invoice arrives as structured data. But the real value comes afterwards—when those data are automatically incorporated into validation, approvals, accounting, archiving and the audit trail.

Companies already using Wflow are therefore not starting from scratch. They have a prepared process into which e-invoices can be incorporated naturally.

Instead of asking:

What will we have to change? they can focus on a more useful question:

Which manual steps will this finally eliminate?

Why You Do Not Need to Replace Your ERP Because of E-Invoicing

One of the most common concerns is:

Will we need to replace our ERP because of e-invoicing?

In most cases, no.

The ERP can remain in place and continue to perform its main role in accounting, record-keeping and reporting.

Wflow acts as a process layer above the existing accounting or ERP system. It manages what happens before the invoice is posted:

• document receipt,
• verification,
• approval,
• validation,
• audit trail,
• secure digital archiving,
• and the transfer of data into accounting.

The goal is not to remove the ERP.

The goal is to eliminate manual work between the invoice, its approval and the accounting system.

That is an important distinction.

Many companies still imagine finance modernisation as a major replacement of their accounting software. But the biggest problem often does not lie within the ERP itself. It lies in everything that happens before the data reach it.

This is where companies encounter:

• delays,
• errors,
• missing approvals,
• and unnecessary searches for documents and information.

Peppol Handles Data Transmission. Wflow Handles What Happens Next

E-invoicing infrastructure such as Peppol helps ensure that a structured invoice is transmitted securely from the supplier to the customer.

But that is not the end of the process.

The invoice may arrive as data, but the company still needs to know what should happen to it next. Who approves it? Who checks it against the purchase order? Does it relate to an existing contract? Who handles an exception? Where can the history of decisions be found?

Peppol handles how the invoice arrives. Wflow handles what happens to it afterwards.

This is where the greatest value for companies is created. Not in receiving the e-invoice itself, but in ensuring that it does not become just another item waiting for manual review.

In Wflow, an e-invoice can continue through the process automatically: into validation, approval, accounting, archiving and the audit trail.

What About Other E-Invoicing Formats?

Across Europe, companies may encounter different national or industry-specific e-invoicing formats. But this does not change the main principle: the invoice format itself is not the final goal.

Whether a company works with PDF invoices, national structured formats or e-invoices exchanged through Peppol, it still needs to manage what happens to the document inside the organisation.

The format helps with the data. The workflow determines whether those data actually become a faster and more reliable accounting process.

That is why e-invoicing should not be viewed only as a legislative or technical change. It is also an opportunity to prepare finance teams to work with structured data.

Different national formats reflect today’s reality in individual markets. Peppol and EU-wide e-invoicing initiatives show the direction in which invoice processing is moving.

How to Implement E-Invoicing With Minimal Operational Change

Introducing e-invoicing does not have to begin with a major system overhaul. On the contrary, the safest approach is gradual implementation.

The company first identifies how invoices actually move through the business today, where the most manual work occurs and which steps are repeated again and again.

Typical examples include:

• re-entering invoice data,
• approvals by email,
• matching invoices with purchase orders,
• supplier checks,
• and searching for the history of previous decisions.

Once this is clear, it makes sense to connect the existing ERP to a process layer in which documents are managed before posting.

In Wflow, companies can configure workflows, roles, rules, approval limits and accounting context so that invoices do not begin accumulating uncontrollably in a new channel.

Only afterwards should the company expand the number of suppliers, invoice types or teams involved.

This allows the business to verify the process, define the rules and help employees become familiar with the new way invoices enter the organisation without disrupting the entire accounting operation.

When E-Invoicing Becomes a Real Benefit

E-invoicing is not a benefit in itself. The real benefit comes when structured data move through the company without manual re-entry, searching or approvals by email.

In a well-designed process, the invoice arrives as data, the system assigns it to the correct workflow, adds the necessary accounting context, sends it to the right approvers and preserves a complete history of every step.

The accounting team no longer needs to routinely re-enter, forward and verify every detail from the beginning. Instead, it can focus on exceptions, discrepancies and control.

For finance teams, this means cleaner data, faster approvals, less dependency on individual employees and better audit readiness.

For the company as a whole, it means less friction between suppliers, accounting, management and operations.

From this perspective, e-invoicing does not become an obligation that companies simply need to survive.

It becomes an opportunity to improve a process that already consumes too much time.

FAQ

Do We Need to Replace Our ERP Because of E-Invoicing?

In most cases, no. Wflow acts as a process layer above the existing accounting or ERP system and helps manage what happens before posting: document receipt, verification, approval, the audit trail and the transfer of data into accounting.

What Does Peppol Handle, and What Does Wflow Handle?

Peppol handles the transmission of structured invoices between suppliers and customers. Wflow handles the subsequent internal process: verification, approval, validation, accounting context, archiving, the audit trail and ERP integration.

What Is the Difference Between National E-Invoicing Formats and Peppol?

National e-invoicing formats define how structured invoices are created or processed in individual markets. Peppol is an international infrastructure for the secure exchange of structured electronic documents between companies and systems.

For finance teams, the key point is that structured data must be connected to internal workflows, approvals and accounting.

Why Is E-Invoicing Alone Not Enough?

E-invoicing ensures that an invoice arrives as structured data. The company still needs to manage who approves it, how it is checked, how exceptions are handled and how the information is transferred into accounting.

How Does Wflow Support E-Invoicing?

Wflow connects incoming documents, approval workflows, accounting rules, the audit trail, the archive and the ERP. This means an e-invoice does not become another isolated input, but part of an automated accounting process.

Can E-Invoicing Be Introduced Gradually?

Yes. A practical approach is to begin with selected invoice types, suppliers or parts of the process where the most manual work currently occurs. Once the workflow has been verified, the scope can be expanded gradually.
