When it comes to e-invoicing, many companies still ask primarily about the cost of the solution. In practice, however, a lack of preparedness for e-invoicing tends to be more expensive than the implementation itself. This article shows where the actual costs will arise in 2027 and what it’s worth preparing in advance.
Failure to prepare for e-invoicing will cost more than just the price of the solution itself
Failure to prepare for e-invoicing will likely cost you more than just the tool fee in 2027. Emergency ERP interventions, manual invoice processing, delays in bookkeeping, and internal chaos between finance, IT, and accounting tend to be much more costly.
The Financial Administration states that, starting January 1, 2027, VAT payers will issue electronic invoices for domestic transactions. At the same time, other businesses must be able to receive them, even if they do not issue them themselves.

That is precisely why it is risky to evaluate e-invoicing based solely on the provider’s price.
Why a Lack of Preparedness for E-Invoicing Will Be More Expensive Than the Solution Itself
Many companies compare only price lists. With mandatory e-invoicing, however, the cost of delaying a decision is also a deciding factor.
If you start late, you’ll suddenly find yourself:
- choose a digital mail carrier
- handle onboarding
- test the ERP system
- set up internal processes
- Test sending and receiving invoices
Such projects do not go over budget because the technology is expensive. They go over budget because they are carried out under time pressure.
Where Do Companies Incur the Highest Costs?
Emergency ERP Integration
The first major expense will arise during an emergency integration. If you don’t know today whether your accounting or ERP system can handle receiving and sending e-invoices in the required format, delaying the process will mean a higher bill later on.
Manual Invoice Processing
If you don’t finish the technical solution on time, someone has to pay the bill:
- accept
- check
- classify
- forward to the accountant
- check the status
With a larger volume, processing invoices manually becomes expensive very quickly.
Slow traffic and chaos
When it is not clear:
- where the e-invoice ends up
- who is supposed to confirm it
- how it is recorded in the books
The number of internal inquiries is increasing, and the company is losing track of what has been delivered, approved, and posted.
A Poor Choice of Partner
If a company chooses a solution based solely on price without verifying integrations, support, and the operating model, it may later have to pay for a second onboarding or switch providers. That’s why it’s important to choose a reliable and certified digital mail provider that will ensure seamless e-invoicing operations.

Who Might Be Most Affected by a Lack of Preparedness for E-Invoicing?
The risk does not apply only to large invoice issuers.
- companies with multiple approval steps between purchasing, finance, and accounting
- organizations with an older ERP system or their own system
- accounting firms and independent accountants
- small businesses and sole proprietors
It is often smaller companies that are at greater risk than they realize. They don’t have an in-house person to oversee the project, and their lack of preparation quickly turns into improvisation.
What You Should Prepare Before 2027
The Financial Administration states that voluntary implementation of e-invoicing will be available starting in 2026. This provides an ideal opportunity to prepare without the pressure of mandatory implementation.
Recommended steps:
An ERP system’s readiness for e-invoicing is often crucial. It’s not enough to know that the vendor’s system “will support” it. You need to know what will actually work.
How to Calculate the Cost of Not Being Prepared for E-Invoicing
Start with reality, not the price list.
- How many invoices do you process each month?
- how many people are affected by them
- How many processes are manual?
This is how the true cost of not being prepared for e-invoicing begins to add up.
In some cases, it will amount to dozens of hours of work; in others, it will mean an overburdened accounting department or delayed IT projects. The principle, however, is the same: the later you start, the more you pay for the time pressure.
Conclusion
The biggest mistake with e-invoicing isn’t usually choosing the wrong solution, but starting too late.
Starting January 1, 2027, the method for issuing invoices for domestic transactions will change, and other businesses will also be required to be able to receive them.
If you want to keep your budget in check and maintain a peaceful work environment, don’t start with the question:
How much does the solution cost?
Ask yourself: How much will it cost you if you’re not prepared for e-invoicing?
The right certified digital mail provider will help you manage the transition without chaos or unnecessary costs.
