Replace rented software with your own

When your software no longer fits your business: time for a solution of your own

For companies whose off-the-shelf software no longer fits their processes and requirements, and who therefore work with workarounds, Excel lists and compromises. We replace it step by step with a solution of your own: with complete data migration, without a big bang and without losing established processes. Whether the switch pays off for you, we calculate beforehand, including the effort of the changeover.

Does this sound familiar?

The software never quite fits, but the invoice arrives every year

Off-the-shelf software is a good start: quick to introduce, ready to use. It becomes a problem when the company works around its limits, with workarounds, Excel lists and compromises nobody chose. Four warning signs we hear in almost every initial assessment:

Your process does not fit the template
The tool dictates the process. Whatever does not fit ends up in Excel lists, emails and workarounds on the side.
Dependent on someone else’s roadmap
Feature requests disappear in the portal, modules are discontinued, pricing models change, and all you can do is watch.
Your data sits with the provider
Limited exports, interfaces cost extra, data protection questions remain open: switching gets harder every year.
Licence costs grow every year
Per user, per module, per month: with every price round of the provider the invoice rises, without you getting more.
Why now?

AI suddenly makes rebuilding off-the-shelf software economical

For a long time, developing software was expensive and slow, and renting off-the-shelf software was the only realistic option. AI-assisted development has turned this calculation around: what SaaS platforms can do can now be rebuilt in a fraction of the time. That is why so many companies are looking at this topic right now:

Rent

Off-the-shelf software (SaaS)

Licence costs per user, year after year
Processes have to adapt to the tool
Data sits in the provider’s cloud
Dependent on price rounds and someone else’s roadmap
Paid for in full, often less than half used
Own

Bespoke development

Invest once, own it for good
Software follows your processes, including special cases
Full data sovereignty, GDPR-compliant in-house
Independent of tech giants and their pricing models
Feasible in weeks rather than years, thanks to AI
The decisive difference

AI delivers the speed, experts deliver operational maturity

Vibe coding tools produce impressive demos in hours. What they do not deliver is operational maturity: data protection, security, performance and maintainability.

That takes software experts who use AI as a tool, not as a replacement.

GDPR-compliant data storage
Secured payments & transactions
Protection against external attacks
Performance under real load
Maintainable architecture for years to come

That is exactly our approach: the speed of AI, combined with 16 years of software craftsmanship. You will see how this works in practice in the next step.

The proven Werkdigital Insight Method®

How we replace your off-the-shelf software
without risk and without downtime

Our experts transfer off-the-shelf software into tailored solutions of your own: step by step, predictably and without interrupting operations. For medium-sized businesses that are not looking for experiments but for a sound business case: what costs you per user and month today will belong to you tomorrow, including data, processes and further development. With a partner who understands your business goals as well as the technology.

01Analysis

Calculate first, then decide

We look at what your off-the-shelf software really delivers and what it really costs: which functions does your team use? Where do workarounds arise? What do licences, interfaces and compromises add up to over five years? The result is a documented process and usage analysis, a reliable cost comparison and a clear recommendation, even if it is “stay with the SaaS”.

Usage & process analysisWhich functions are actually used and where workarounds arise, gathered from data and interviews with your team.
Cost comparison & business caseLicence and follow-up costs over several years compared with the investment in and operation of your own solution, including a funding check.
Replacement path & budgetingRecommended approach, cost estimate, timeline, resources, including presentation material for your committees.
02Concept

Tailored instead of an 80 per cent compromise

We design the new solution around your actual processes, not around a feature catalogue. You see an interactive clickable prototype early on, the data migration from the SaaS is planned, and interfaces to third-party systems are defined. The result is an implementation plan with detailed costing as an agile fixed-price contract.

Migration & data strategyExport from the SaaS, data cleansing, parallel operation, fallback scenarios and interfaces to third-party systems.

03Solution

Replacement in live operation

We implement while your team keeps working with the off-the-shelf software: agile two-week sprints, first modules in production after a few weeks. Every stage is tested, migrated data is validated, and the SaaS contract is only cancelled once your own solution has proven itself. After that, we keep developing so that the solution keeps pace with your company.

Agile implementationTwo-week sprints, old and new in parallel operation, continuous progress monitoring: first modules in production early on.
Migration & final acceptanceTested data migration, end-to-end tests, training, commissioning, source code and architecture documentation.
Operation, support & further developmentService contract, monitoring, regular updates and up-to-date documentation: your solution stays current, with no licence fees.
And what does it bring?

Six effects you will notice
in your daily work straight away

Replacing software is not an end in itself. It pays off where off-the-shelf software holds you back today: in costs, processes, data, and in what your company plans to do next.

Software follows your process
No workarounds, no Excel lists alongside the tool: the solution reflects your processes, including special cases.
Independent of the provider
No price increases, no discontinued modules, no outside roadmap: you decide what changes and when.
Full data sovereignty
Your data is stored where you decide: GDPR-compliant, exportable and without depending on someone else’s cloud.
Ready for what comes next
Interfaces, mobile apps, analytics, AI: what failed because of the provider’s feature catalogue becomes possible on your own platform.
Grows with you, at no extra cost
New users, new sites, new requirements cost no additional licences: the solution scales with you.
Licence costs disappear
Invest once instead of renting every year: no costs per user, per module or per price round of the provider.

Good news: the state covers up to 80%

For medium-sized companies with fewer than 250 employees, up to 80% of certain consulting and audit services are currently eligible for funding, for example through the INQA programme. Which programme applies in your case, even if your company is larger, we clarify in the initial assessment.

A success story from practice

Bespoke project software for an engineering firm: calculated benefit between €80,602 and €155,834 per year

An engineering firm for municipal energy infrastructure projects has been managing its projects with rented project software for years. The software has aged and no longer meets the management’s requirements, especially for steering ongoing projects. The biggest loss occurred in a place that never appeared in any report: change orders were submitted too late because nobody noticed in time that the scope of work had grown.

Before the decision, we calculated the expected benefit of a solution of their own together with the management, based exclusively on figures the company provided itself.

Up to the complete commercial core, the investment pays for itself in the medium scenario after around 15 months. The licence costs that will no longer apply are deliberately not included.

The new software is designed to report automatically as soon as a project’s costs deviate from the agreed budget. It is currently in development; first productive use is planned for the second quarter of 2027.

Process

A transparent process from the initial assessment to cancelling the SaaS contract

You do not need to bring process documentation or a specification. We start with what is there and make every step transparent before you commit.

Initial assessment & brief analysis

1

You describe your software, costs and pain points to us. We give you an honest initial assessment: does a replacement pay off in your case, and roughly what would it involve?

Analysis & advice

2

We establish what is actually used and what continued operation costs, and show you which approach makes sense. You decide on working together on the basis of figures; “stay with the SaaS” is a valid outcome too.

Replacement in live operation

3

We implement step by step: off-the-shelf software and your own solution run in parallel, first modules are in production after a few weeks, data migration is tested and validated, without a big bang and without downtime.

Cancel & keep developing

4

The SaaS contract is only cancelled once your own solution has proven itself in live operation. After that, we keep technology and documentation up to date and continue development, at your company’s pace rather than someone else’s roadmap.

FAQ

Common questions

Do you have questions? Here you will find answers to the topics decision-makers from medium-sized businesses ask us most often before a SaaS replacement.

That depends on the number of users, the term and the need for customisation, which is why every project starts with a cost comparison over several years: licence, interface and workaround costs against investment, changeover effort and operation of your own solution. Break-even is often reached after a few years. If the numbers do not add up, we tell you so.

In almost all cases, yes: via export functions, interfaces or structured extracts. We check the data situation during the analysis, plan cleansing and migration, and validate the migration before the switch. At EU level, the Data Act also strengthens your right to your own data.

The analysis records in advance which functions are actually used: your own solution rebuilds exactly these and adds what was missing. Should something come up during operation, it is developed later: unlike with a SaaS provider, nobody but you decides whether a feature comes.

No. Old and new run in parallel: functions are switched over step by step and tested at every stage. The SaaS contract is only cancelled once your own solution has proven itself in live operation. We plan notice periods in from the start.

The initial assessment is free of charge and the analysis is at a fixed price; we give you the specific budget in the initial assessment because it depends on scope and data. We quote the implementation after the concept as an agile fixed price. The comparison always includes one more question: what will the licences cost over the next five years?

Get started

With every contract year, only the invoice grows
not the benefit.

Every contract year makes switching harder: the amount of data at the provider grows, workarounds become entrenched, the licence bill rises. In the free initial assessment, you get an honest assessment of whether a replacement pays off for you, and what continuing with the off-the-shelf software really costs you.
