Digital Transformation in Small and Medium-Sized Businesses: What It Really Costs
Table of Contents
The cost of digitalization for small and medium-sized businesses can be quantified—but not with a single figure that applies to all companies. The KfW Digitalization Report 2024 cites digitalization expenditures of approximately 25,000 EUR per year per company. Companies with 50 or more employees spend an average of just under 216,000 EUR. Both figures come from the same survey. If you base your planning on the average, you’re not taking your own company’s specific needs into account.
In this article, “digitalization in small and medium-sized businesses” refers to the process of migrating core operational processes—such as quote preparation, order processing, scheduling, and billing—from emails, Excel spreadsheets, and verbal instructions to digital systems. A website, cloud storage, and digital accounting are basic requirements. However, these alone do not make a business a digitalized business.
This article shows what budgets companies with 75 to 200 employees should realistically expect: the cost ranges for digital transformation projects, which items are often missing from quotes, and how to verify each figure.
Why the KfW average of 25,000 EUR doesn't apply to your business
The KfW 2024 Digitalization Report for Small and Medium-Sized Enterprises provides the most reliable figures available on this topic. In 2023, small and medium-sized enterprises in Germany collectively spent 31.9 billion EUR on digitalization projects. Companies actively pursuing digitalization invested an average of around 25,000 EUR per year.
The average masks the extent to which spending varies with company size:
Company Size | Average Annual Digitalization Expenditures (2023) |
|---|---|
Fewer than 5 employees | about 8,000 EUR |
5 to 10 employees | about 14,300 EUR |
10 to 50 employees | about 42,000 EUR |
50 or more employees | about 215,500 EUR |

A company with 50 or more employees spends, on average, 27 times as much as a microenterprise. This isn’t due to waste, but rather to operational complexity: A freight forwarding company with 100 employees, less-than-truckload and full truckload shipments, 40 subcontractors, and 200 orders per week operates a different system landscape than twenty five-person companies combined. The number of employees is merely a visible approximation. What actually determines the costs is the number of process variations, interfaces, and people working simultaneously with the same data.
To put these figures in context: The KfW averages include all digitalization expenditures for a given year—licenses and hardware as well as external development, often for multiple projects running in parallel. The budgets mentioned in this article, on the other hand, refer to individual projects.
For companies of this size, the question “How much does digital transformation cost for small and medium-sized businesses?” is therefore misguided. The right question is: How much does each stage of digital transformation cost, and at what point does it become profitable?
The Three Cost Levels of Digitalization in Small and Medium-Sized Businesses
In practice, digitalization expenditures fall into three categories that differ fundamentally in terms of budget, nature, and impact. By distinguishing between them, you can classify proposals and describe your own project precisely.
Level 1: Basic Digital Infrastructure – Ongoing Costs, No Project
Microsoft 365 or Google Workspace, document management, digital accounting, and an out-of-the-box CRM. You buy these tools as-is. The costs are ongoing.
Here’s a sample calculation for a company with 80 employees: 50 EUR in licensing costs per employee per month across all tools × 80 employees × 12 months = 48,000 EUR per year. That’s the cost of staying productive, not of digitalization. Many companies consider themselves digitized at this stage simply because software is running everywhere. In reality, standard tools are in use, while operational processes continue to exist in email inboxes and Excel files in between. If this tool landscape grows unchecked over the years, it leads to uncontrolled SaaS proliferation. We explain why more tools don’t solve operational complexity in the article about SaaS Proliferation and Operating Platforms described.
Phase 2: Digitizing an operational function – starting at 50,000 EUR
At this stage, a single process is integrated into a system that operates exactly like your business. Example: Quote preparation for a freight forwarding company. Today, rate schedules, tolls, diesel surcharges, and subcontractor rates are stored in three Excel files; each quote takes 40 minutes to prepare and relies on two experienced dispatchers. A costing system that replicates this logic typically costs between 50,000 and 90,000 EUR, depending on the interfaces and data availability.
This level is appropriate when a single function costs a measurable amount of time or margin, but the rest of the system landscape can handle it. For projects under 50,000 EUR, custom development for an operational function is rarely costed properly—what’s usually missing are error handling, access control, and integration with existing systems—in other words, precisely the components that turn a prototype into a working tool.
Phase 3: A core operational system – 75,000 to 150,000 EUR
At this stage, the system that actually powers the business is developed: quotes, orders, scheduling, and billing are integrated into a single, end-to-end platform connected to ERP and accounting systems. For companies with between 75 and 200 employees, the total cost typically ranges from 75,000 to 150,000 EUR, plus ongoing costs for operation and further development (more on this below).
There is no set format for this. In practice, we see three models: an operational platform that sits on top of existing tools and connects them; a central order management system that replaces Excel and email coordination and integrates with the ERP; or the replacement of a legacy system that the business has long outgrown. Your system landscape—not a vendor’s catalog—determines which pattern is right for you. At this stage, AI-powered automation also becomes economically viable. What AI Costs and Delivers for Small and Medium-Sized Businesses, we've listed them separately.
A core operational system is an infrastructure decision. It pays for itself not over a single quarter, but over the course of years, and it requires that the organization treat it as infrastructure: with a budget for operation, maintenance, and expansion.
What Determines the Price Within a Cost Tier
Two quotes for the same project can differ by as much as 40,000 EUR, without either of them being unreliable. The difference is almost always due to four factors.
Interfaces. Every stable integration—ERP, accounting, telematics, customer portal—is a separate work package. An integration with proper error handling, monitoring, and testing rarely takes fewer than five person-days; at daily rates of 1,000 to 1,200 EUR, that amounts to 5,000 to 6,000 EUR for a simple interface. Complex ERP integrations cost several times that amount. Three more or fewer interfaces often account for the bulk of the difference in quotes.
Data migration. Cleaning up and migrating master data from three generations of Excel and a legacy system is a project in itself, not a mere formality. If it’s not included in the proposal, it will be added later as an addendum.
Process Variants. Every special case—express orders, partial deliveries, different billing for key customers—involves logic that must be specified, built, and tested. Twenty variants cost more than five, regardless of the provider.
Own contribution. The extent to which your own team handles the work significantly affects the external bill. We've compared whether in-house development, an agency, or a hybrid model works best for your business. In-House Development vs. Agency calculated.
The items that aren't listed in any offer
The construction cost is the most visible part of the digitization expenses. There are four items that are sure to be added, and none of them are included in a service provider’s quote.
Internal project time. A core system cannot be developed without your knowledge of your processes. A realistic estimate for a Level 3 project: a project manager at 6 hours per week × 26 weeks × 70 EUR full cost per hour = 10,920 EUR. In addition, two key users at 3 hours per week each × 26 weeks × 55 EUR = 8,580 EUR. Together, this amounts to approximately 19,500 EUR in internal costs—work time that is lost from day-to-day operations and must be factored into the schedule.
Introduction. Training, parallel operation, post-go-live adjustments: The weeks following the rollout will determine whether the system is adopted or ends up running alongside the old Excel files. To learn how to manage this phase without overburdening your operations team, see the article on Change Management in Digital Transformation.
Operation and Further Development. Estimate 15 to 20 percent of the total construction cost per year: for a system costing 100,000 EUR, that means 15,000 to 20,000 EUR annually for hosting, updates, troubleshooting, and the expansion that will be required after six months of operation. This article explains why a business-critical system can become a financial burden without this budget MVP vs. Production System.
Transition costs. Old licenses remain valid during the transition. It is normal for individual tools to operate in parallel for six to twelve months, and this should be factored into the budget from the outset.
Total for a typical Level 3 project: 95,000 EUR in construction costs + 19,500 EUR in internal project time + four years of operation at 17,000 EUR per year = approximately 182,500 EUR over five years. That is the figure that should be factored into the investment decision. Anyone who budgets only for the construction cost is basing their decision on only half the total cost.
Three Sample Budgets: Freight Forwarder, B2B Service Provider, Manufacturing Company
Three typical scenarios from real-world project practice illustrate how cost levels and miscellaneous items come together to form actual budgets.
Freight forwarding company, 100 employees – Level 2. The quote calculation—which includes rate schedules, tolls, and subcontractor prices—replaces three Excel files; the ERP system remains the leading system. Total cost: 65,000 EUR + approximately 9,000 EUR for internal project time (shorter duration, one key user) + four years of operation at 11,000 EUR per year = approximately 118,000 EUR over five years.
Technical B2B service provider, 90 employees – Level 3. Resource planning, reports from the field, and billing are all integrated into a core operational system, which is linked to accounting. Here is the calculation example from the previous section: approximately 182,500 EUR over five years.
Medium-sized industrial company, 150 employees – Level 3 with deep integration. Order processing and production planning in a single core system, deep ERP integration, data migration from a legacy system. Total cost: 140,000 EUR + approximately 25,000 EUR for internal project time + four years of operation at 24,000 EUR per year = approximately 261,000 EUR over five years.
The range of 118,000 to 261,000 EUR over five years shows why reputable providers only quote a price after conducting an assessment: Depending on the system environment, the same question can cost more than double.
Compare the costs of digitization with the status quo
182,500 EUR over five years sounds like a lot—as long as there’s no figure for comparison. That figure is the cost of “business as usual,” and it doesn’t appear in any financial records because it’s spread out across salaries, overtime, and lost profit margins.
Here’s a real-world example from a logistics company with 80 employees: Order coordination via email, Excel, and phone ties up—across scheduling, fleet management, and billing—a conservative estimate of 15 hours per week. At 55 EUR in full costs per hour and 48 work weeks, that amounts to 15 × 48 × 55 = 39,600 EUR per year. This calculation covers a single process chain, excluding error costs from duplicate data entry and excluding orders that are left unfulfilled because the quote was sent out two days too late.
Over five years, this amounts to approximately 198,000 EUR in status quo costs versus 182,500 EUR in system costs—and that’s before even factoring in the items that are more difficult to measure. Whether this calculation works out the same way for you depends on your own figures.

Subsidies lower the price, not the responsibility
The funding landscape for digitalization is constantly changing: Federal programs are coming to an end, state programs vary, and eligibility requirements change. Funding loans for digitalization projects—such as those offered by KfW—and the free initial consultation provided by the Mittelstand-Digital Centers are generally reliably available.
Our stance on this: A digitalization project that is only viable with a grant is not viable. Grants stretch the budget, but they do not replace either the status-quo budget or the operating budget. And they come at a cost that is rarely quantified: application and approval processes lasting several months, during which the coordination costs from the calculation example above simply continue to accrue. Consider applying for funding after the system decision has been made, not as the basis for that decision.
How appleute Calculates Digitalization Budgets
We begin every project with a discovery phase, during which we assess processes, interfaces, and the data landscape before any figures are determined. Afterward, we calculate costs within the ranges described in this article: individual operational functions starting at 50,000 EUR, core operational systems between 75,000 and 150,000 EUR, and 15 to 20 percent of the total project cost per year for operations and further development, factored into the budget from the start. We provide the calculation methodology for each figure so you can justify it internally.
You should expect the same level of transparency from every provider. In our guide, we’ve listed the ten questions that can help with this—including those for us— Selecting a Software Development Partner compiled.
What to do now
First, quantify the current situation for a single process chain. Have someone track for a week exactly how many hours are actually spent on preparing quotes or coordinating orders, and calculate the full costs. This single figure makes every quote comparable.
Next, determine your cost tier. Is your system infrastructure up to par, but just one function is holding you back? Then choose Tier 2, starting at 50,000 EUR. Is your operation running on email, Excel, and verbal communication between tools? Then a Level 3 core system is the honest answer, with a total cost of 75,000 to 150,000 EUR.
Budget for the full cost: construction costs plus 15 to 20 percent for internal project time plus 15 to 20 percent for annual operations. If this total compares favorably with your current costs, the decision is no longer a matter of courage but a matter of math.
If you want to know which tier applies to you and how much it costs, we'll calculate it for you using your numbers.
