Electronic Invoicing: Complete Guide to Prices and Costs

/in /by

How much does electronic invoicing really cost for a business? This is a question many entrepreneurs are asking as electronic invoicing becomes increasingly important.

Businesses may have to choose between free invoicing software, paid subscriptions, usage-based pricing and solutions that provide access to an approved platform. Other expenses can also arise, including legal archiving, employee training, technical configuration and integration with existing accounting or ERP systems.

The cheapest solution is not necessarily the most cost-effective one. The overall cost depends on the number of invoices processed, the features required, the level of automation and the tools already used by the company.

This guide explains the main costs to anticipate, the different pricing models available and the practical steps businesses can take to keep their electronic invoicing expenses under control.

KEY TAKEAWAYS

  • The cost of electronic invoicing goes beyond the price of invoicing software or a digital platform.
  • Processing a paper invoice is often estimated at between €14 and €20, whereas a structured electronic invoice can cost only a few euros.
  • With a high level of automation, the cost of processing an electronic invoice can fall below €1.
  • Pricing varies according to features, invoice volumes and integrations with tools such as ERP systems.
  • Some solutions are free, while others use monthly subscriptions or charge for each document processed.
  • Additional costs may apply for legal archiving, initial setup, employee training, additional users or technical integration.
  • Preparing the transition properly can reduce administrative errors, limit unnecessary expenses and save considerable time.

What Budget Should You Plan for Electronic Invoicing?

The cost of switching to electronic invoicing cannot be determined simply by looking at the monthly price of a software package.

A realistic budget should include expenses related to invoicing software, approved platforms, compliance, document processing, integration and the time employees spend managing invoices.

Visible Costs and Less Obvious Expenses

Electronic invoicing costs can generally be divided into two categories: direct and indirect costs.

Direct costs are the expenses that are easiest to identify, such as:

  • invoicing software subscriptions;
  • access to an approved platform;
  • legal archiving;
  • additional modules or services.

Indirect costs are less visible. They may include the time spent correcting invoices, checking information, following up on payments or carrying out manual administrative tasks.

This distinction is important because a solution with a slightly higher subscription price may actually be cheaper overall if it significantly reduces manual work.

Why Software Pricing Alone Does Not Show the Real Cost

The price advertised for invoicing software represents only one part of the overall budget.

A suitable solution can help businesses:

  • reduce manual data entry;
  • minimize errors;
  • simplify accounting processes;
  • speed up invoice processing;
  • improve payment monitoring.

Some companies assume that they need an expensive system to comply with electronic invoicing requirements. In reality, several solutions already provide essential features at a relatively low cost, and some are available free of charge.

The right approach is therefore to assess the company’s actual requirements before choosing a pricing plan.

Electronic Invoices: Are They Really Cheaper Than Paper Invoices?

Electronic invoicing can initially appear to be an additional business expense. However, the cost should also be compared with the expense associated with traditional paper invoices.

A paper invoice typically involves printing, preparing the envelope, postage, mailing, receiving, entering information into accounting software, filing and monitoring.

Electronic invoicing eliminates or automates many of these steps.

Cost Comparison by Invoice Type

According to commonly used estimates, processing a paper invoice can cost between €14 and €20.

A structured electronic invoice, by comparison, generally costs only a few euros to process. With an efficient level of automation, the cost can even fall below €1 per invoice.

Invoice type Estimated average cost
Paper invoice €14–€20
Structured electronic invoice A few euros to less than €1

The difference is mainly explained by:

  • automated transmission of invoice data;
  • reduced manual entry;
  • fewer administrative operations;
  • faster accounting processing.

When Does the Investment Become Profitable?

The point at which electronic invoicing becomes financially worthwhile depends largely on the company’s invoice volume and the level of automation.

The more invoices a business processes, the more significant the potential time savings become.

An appropriate electronic invoicing system can help businesses:

  • process invoices more quickly;
  • reduce administrative mistakes;
  • improve payment monitoring;
  • simplify accounting workflows;
  • save employees valuable time.

For companies handling a significant number of invoices, these cumulative savings can offset the cost of the software or platform.

What Are the Prices of Approved Platforms in 2026?

Once the overall cost of electronic invoicing has been considered, the next step is to understand how different platforms charge their customers.

The market includes free tools, monthly subscriptions and pay-per-use solutions. Some providers also combine a fixed subscription with additional charges based on the number of documents processed.

The most appropriate option depends on the company’s size, invoice volume, automation requirements and existing software environment.

Free Tools, Monthly Subscriptions or Pay-Per-Use: What Is the Difference?

Some free solutions provide enough functionality for the invoicing needs of many small businesses and very small enterprises.

Other platforms offer more advanced features, generally through paid plans. These may include greater automation, payment tracking, business management functions or integrations with other software.

Advanced solutions may provide features such as:

  • payment monitoring;
  • connections with other business tools;
  • commercial management;
  • more advanced automation.

Several pricing models are currently available:

Pricing model Typical price
Free solution Free
Small business subscription €7–€25 / month
SME plan €40–€150 / month
Per-invoice pricing €0.20–€0.80 / document

Some platforms combine a monthly subscription with an additional charge based on the number of invoices or documents processed.

Businesses should therefore carefully examine what is included before comparing prices.

How Much Do Approved Platforms and Software Integrations Cost?

Electronic invoices will need to pass through an approved platform as part of the electronic invoicing framework.

Some solutions include access to the relevant platform within their standard pricing. Others may charge additional fees depending on the services required.

Additional charges may apply to:

  • invoice transmission;
  • advanced modules;
  • additional users;
  • ERP integration;
  • technical configuration.

The final cost depends heavily on the company’s existing IT environment.

A small business using one invoicing tool may require very little configuration. A company using several accounting, sales and ERP systems may need a more complex integration process.

What Is an ERP?

ERP stands for Enterprise Resource Planning.

An ERP system brings together different business processes, such as accounting, purchasing, sales, inventory and financial management, within a connected software environment.

Connecting electronic invoicing to an ERP can improve automation, but technical integration may generate an additional cost.

What Additional Fees Can Increase the Final Cost?

The monthly subscription is not necessarily the only expense.

Additional costs may appear during implementation or when a company needs more advanced functionality.

Potential additional expenses include:

  • legal invoice archiving;
  • initial configuration;
  • employee training;
  • additional users;
  • exceeding the invoice volume included in the plan;
  • ERP or software integration.
Additional cost Typical price
Legal archiving €5–€30 / month
Additional user €5–€15 / month
ERP integration €200–€2,000

Some platforms may also support regulated electronic invoice formats such as Factur-X and UBL (Universal Business Language).

Using the appropriate format and ensuring that invoice data complies with the applicable requirements is important. A non-compliant invoice may need to be corrected, potentially causing processing delays and additional administrative work.

How Can You Keep the Cost of the Electronic Invoicing Reform Under Control?

Businesses can reduce some of the costs associated with the transition by preparing early and selecting their tools carefully.

Rather than choosing a platform simply because it has the lowest advertised price, companies should assess their actual invoicing volume, software environment and automation requirements.

Compare Solutions Before Choosing a Platform

An extremely comprehensive solution may be unnecessarily expensive for a small business that only needs basic invoicing functionality.

On the other hand, choosing a platform that is too limited may create additional manual work and ultimately increase administrative costs.

Before selecting a solution, check:

  • which features are included;
  • which services are charged separately;
  • invoice volume limits;
  • additional user fees;
  • compatibility with existing software;
  • accounting integration capabilities;
  • available automation features.

A small business and a company processing hundreds or thousands of invoices each year will not have the same requirements.

Prepare the Transition to Avoid Unnecessary Expenses

Planning the transition in advance gives employees time to adapt to new processes.

A well-prepared implementation can help:

  • reduce rejected invoices;
  • minimize corrections;
  • improve internal communication;
  • reduce manual operations;
  • save time on day-to-day administration.

A gradual implementation also makes it easier to identify technical or organizational problems before the system becomes fully operational.

Can an Accountant Help Reduce Electronic Invoicing Costs?

The cost of electronic invoicing is not determined solely by the software selected.

Professional accounting support can also help businesses evaluate their requirements, select suitable tools and organize their accounting workflows more efficiently.

Professional Support Can Prevent Costly Mistakes

An accountant can help with areas such as:

  • assessing the company’s needs;
  • selecting appropriate software;
  • configuring invoice flows;
  • connecting invoicing tools with accounting systems;
  • checking electronic invoice formats;
  • anticipating regulatory developments.

A poorly chosen technical solution can generate additional expenses later, particularly if the company needs to change its configuration or connect several systems.

Professional guidance can also help businesses automate accounting processes and reduce unnecessary back-and-forth caused by missing or incorrect information.

The goal is therefore not simply to find the cheapest solution, but to identify the best balance between price, compliance, automation and ease of use.

Combining Digital Tools With Human Expertise

Digital solutions can automate many repetitive processes, while professional support provides a broader view of the company’s accounting and administrative organization.

This combination can help businesses:

  • secure accounting processes;
  • improve financial management;
  • simplify administrative procedures;
  • speed up information flows;
  • reduce time spent on repetitive tasks.

Technology makes it easier to exchange and process data, while professional advice helps businesses adapt to regulatory and operational changes associated with electronic invoicing.

What Electronic Invoicing Requirements Apply From 2026?

The electronic invoicing reform represents a gradual change in how businesses issue, transmit and process invoices and related data.

Companies should therefore anticipate the applicable changes and make sure that their invoicing tools will be compatible with the relevant requirements.

The precise obligations and implementation timetable may depend on the type of business and the transactions involved.

What Features Are Included in Electronic Invoicing Software?

Features depend on the provider and the pricing plan selected.

Depending on the solution, businesses may have access to:

  • invoice creation and issuing;
  • quotation management;
  • payment tracking;
  • automated processes;
  • invoice archiving;
  • accounting integration;
  • ERP integration;
  • electronic invoice format management.

For this reason, the price should always be assessed alongside the features that the business actually needs.

Is Price the Only Factor to Consider?

No.

A cheaper solution is not necessarily the least expensive option over the long term.

Businesses should also consider:

  • automation;
  • invoice volume limits;
  • additional charges;
  • integrations;
  • ease of use;
  • compliance features;
  • scalability.

A platform that costs a little more but significantly reduces manual processing may provide better value than a cheaper solution requiring extensive administrative intervention.

IN SUMMARY

Electronic invoicing represents a major change in the way businesses manage their invoices and accounting information.

Although the transition requires some planning and potentially an initial investment, it can also create an opportunity to automate repetitive processes, reduce administrative work and improve accounting efficiency.

The final cost mainly depends on:

  • the solution selected;
  • the number of invoices processed;
  • required features;
  • automation level;
  • software integrations;
  • archiving requirements;
  • number of users.

To control your budget, focus on the following priorities:

  • Compare several solutions before committing.
  • Check all additional fees.
  • Review invoice volume limits.
  • Confirm compatibility with your existing software.
  • Plan integrations in advance.
  • Prepare employees for the transition.

Poor preparation can lead to invoice errors, additional costs and administrative delays.

A structured approach, on the other hand, makes it easier to select a solution that matches the company’s size and needs while turning electronic invoicing into an opportunity to improve productivity and streamline accounting processes.
