End Tool Sprawl: One Data Basis Is Enough

In many professional services firms, day-to-day work now runs across three to five different systems at once. A separate time tracking tool for employees, a project management board such as Jira for technical delivery, separate software for invoicing and often yet another tool for travel expenses. Each team chose the solution that best fits its own step in the process. The result is tool sprawl, and it costs more time than the individual tools will ever save.

The real pain arises at the handovers between systems, when data has to be moved manually from one tool to the next. Project leads export hours from the time tracking tool, reconcile them with the status in Jira and transfer the billable hours into the invoicing software by hand. Every one of these handovers produces errors, figures diverge and deadlines pass.

The key facts from this everyday reality can be summed up quickly:

• Time tracking, project management and invoicing run in separate tools without a shared data basis.
• Billable hours are exported manually from the time tracking tool and transferred into the invoicing software.
• Every manual handover is an additional source of error, from wrong hourly rates to hours recorded twice.
• Utilization, margin and project costs can only be analysed with a delay, because data from several systems has to be merged.
• Without clear governance, every team decides on new tools independently, so the tool sprawl keeps growing.
• Forecasts are based on outdated exports instead of current project data.

An example from practice: a consultant books their hours correctly in the time tracking tool, but in the meantime the project is moved to a different cost object in Jira. Invoicing draws on the old status, the item ends up on the wrong client invoice, and the correction costs accounting several hours of rework at month-end. Multiplied across several projects and employees, this adds up to a real cost problem.

For management, this means that decisions are based on figures that are already out of date when they are analysed. If you only work out a project's margin at month-end from three exports, you can hardly correct course and are merely documenting what has already gone wrong. This is exactly the point at which tool sprawl turns from an annoying detail into a management problem.

Why German mid-sized companies are rethinking software selection

There is a noticeable shift in how project-based businesses select software. Instead of buying an international point solution for every process step, German mid-sized companies (the Mittelstand) are increasingly turning to specialised software from mid-sized German IT vendors. A joint study by the German Association of IT SMEs (Bundesverband IT-Mittelstand, BITMi) and the University of Potsdam from June 2026 shows that 44.3 percent of German mid-sized companies already use business software from mid-sized IT vendors instead of solutions from large international corporations. Even among large enterprises, more than 20 percent rely on mid-sized IT vendors.

The reasons are close to the everyday reality of professional services firms themselves:

• Closeness to German requirements such as the Working Hours Act (Arbeitszeitgesetz, ArbZG), the GDPR and billing that complies with the German principles of proper bookkeeping (GoBD).
• Direct support instead of international ticket queues with long response times.
• Software built for the structure of professional services firms, with projects, hours and budgets at its core, instead of generic enterprise software that first has to be customised at great effort.
• Lower risk of dependence on individual international cloud platforms.

For IT consulting, management consulting and engineering firms, this has direct consequences for software selection. It is not enough to look for the most powerful individual tool for time tracking or project management. What matters is whether the solution can be integrated into a shared data basis with your other processes, or whether it becomes yet another island in your own tool sprawl.

There is another practical aspect: vendors from the German IT Mittelstand usually develop their software together with their customers over many years, instead of managing it as part of a global product portfolio. For professional services firms, this means shorter paths for change requests, for example when new requirements arise for project billing or statutory documentation obligations. When selecting software, it is therefore worth checking not only the feature set but also how close the vendor is to your market and your company size.

From a best-of-breed patchwork to a consolidated platform

A typical setup in consulting and engineering looks like this: a separate time tracking tool for employees, Jira for managing projects and tasks, plus a standalone invoicing tool for billing. Each tool is good on its own; the problem arises at the interfaces between them.

Every interface between two systems is a potential source of error: formats do not match exactly, project numbers are assigned differently, hourly rates have to be maintained twice. If a project is renamed in Jira but the change is not carried over into time tracking, utilization and invoices no longer match at month-end.

The problem is most visible in billing. Project leads have to pull hours from the time tracking tool, reconcile them with the actual project progress in Jira and transfer the billable items into the invoicing software by hand. With ten or twenty parallel projects, this becomes a recurring effort that ties up capacity actually needed for project work.

On top of that comes a cost factor that rarely appears in budget planning: maintaining the interfaces themselves. Every update to one of the tools involved can break an existing connection to the other systems, creating extra coordination effort between IT, project management and accounting. Best-of-breed combinations look flexible on paper; in practice they permanently tie up resources for maintenance instead of management.

Clarify processes and goals first, then choose software

The most common mistake in software selection is to look for features first and only think about processes afterwards. If you start with your own workflows instead, for example: how does an hour flow from booking to invoice? Who needs which report, and how often?, you end up with a clearer list of requirements.

On this basis, you can check whether a new individual tool really adds value or just creates another data source that later has to be exported and reconciled again. This check should come before every purchase decision, not after it.

It also makes sense to involve project management, accounting and IT in the evaluation from the start, because each of these roles places different demands on the same data. Accounting needs clean billing data, project management needs an up-to-date view of utilization, and IT needs a maintainable and secure system landscape. If these perspectives are only brought in after the purchase decision, the pattern that created the tool sprawl in the first place repeats itself.

Consolidate step by step instead of a big bang

Consolidating your tools does not have to happen in one single large project. The more practical route is to start with the process that currently causes the most friction, usually time tracking, and grow from there step by step.

ZEP is built for exactly this route. ZEP Clock is a separate line that covers working time tracking only, from €4.50 per user per month; switching to other lines is not intended there. The entry point for project business is ZEP Track for project time tracking, from €9 per user per month. Building on this, ZEP Control maps project management and project controlling on a shared data basis, from €19 per user per month. For companies that also need Invoicing and commercial management in one system (Resource Planning is available as an add-on), ZEP Operations covers the complete project lifecycle as a PSA solution, from €29 per user per month. If you manage several legal entities, ZEP Business is the ERP for Professional Services.

The decisive difference from a best-of-breed combination is the single data basis. Hours, projects, budgets and invoices come from the same source, without exporting and re-importing between systems.

One data basis, one question

Since September 2026, consolidating onto one data basis has had a second effect: it makes your data searchable by question. The ZEP Assistant, the built-in AI chat in ZEP, answers questions across all areas, because hours, projects, absences and assignments are in the same system.

“Who on my team is on holiday this week?” “Which projects are over budget?” “Who has free capacity for project X?” In a landscape of five systems, that would mean three logins and an Excel reconciliation. In ZEP, it is a conversation.

This is the opposite of adding another tool to the stack: the Assistant does not add a new data silo. It makes the existing one accessible, with roles, permissions and an audit trail. Included as standard in ZEP Track, ZEP Clock, ZEP Control, ZEP Operations and ZEP Business.

Clear criteria for selecting software

If you want to consolidate your tool landscape, you can use five criteria as a guide:

• A shared data basis instead of an isolated solution: do hours, projects and invoices stay in one system without exports?
• Modular expansion: can the software be extended without replacing the existing solution?
• Governance: are there clear responsibilities for who may introduce new tools?
• A precise fit for professional services firms instead of generic enterprise software.
• Transparent, predictable costs per user and month.

Specific scenarios for three industries

An IT consultancy with 60 employees managing projects for several clients in parallel benefits above all from the connection between project controlling and invoicing: billable hours flow directly from the project into billing, without manual reconciliation with a separate tool.

A management consultancy with frequent travel and changing project teams needs above all a clean connection between time tracking, travel expenses and the project budget, so that the actual margin per project is visible and does not only show up after the month-end close.

An engineering firm with long-running projects and several disciplines needs above all resource planning and utilization management across several projects, functions that come together with commercial management in ZEP Business; in ZEP Operations, Resource Planning is available as an add-on.

The same principle applies in all three scenarios: what matters for getting started is the process step that currently causes the most manual work, not the largest available feature set. Only after that does it make sense to expand towards project controlling, resource planning or commercial management.

When ending tool sprawl pays off

In most companies, tool sprawl only becomes a topic for management when one of three triggers occurs:

• Growth: new employees and new projects push existing individual tools to their limits.
• Margin pressure: projects are priced more tightly, and inefficient manual processes become visible as a cost factor.
• A management decision to consolidate: management or the head of IT sets the goal of deliberately reducing the number of tools in use.

In all three cases, the same question arises: is a complete new rollout with high risk worth it, or can the problem be solved step by step? A modular platform answers this question pragmatically. Instead of replacing time tracking, project management and invoicing all at once in one large project, the rollout starts where the pain is greatest, usually time tracking, and grows from there into other areas.

This approach considerably reduces the project risk of a software rollout. Employees get used to one system step by step instead of five new tools at once, and the IT department can validate each step before the next one follows.

This approach is also easier to justify in budget planning than replacing all systems in one go. Each expansion stage, from ZEP Track through ZEP Control to ZEP Operations, can be budgeted individually and checked against the benefit achieved before the next investment is due. This makes internal approval easier, especially when margin pressure is already weighing on ongoing projects.

You can calculate what this means for your company size directly with the price calculator, including the tiers between ZEP Track, ZEP Control and ZEP Operations.

In the end, the maths is simple: every hour that currently goes into manual handovers between tools is missing elsewhere, for actual project work or for strategic management by the leadership team.

Such a project can be planned realistically: switching to shared time tracking is usually productive within a few weeks, and the expansion to include project controlling and invoicing follows over the next months, depending on the complexity of the existing project structures. This pace allows you to reduce tool sprawl in a controlled way instead of trading it for a new risk through a rushed large-scale project.

Conclusion: the next steps against tool sprawl

Tool sprawl does not disappear on its own; it keeps growing with every new tool introduced without coordination. The first step is an honest inventory: how many systems are currently in use, where do most manual handovers happen, which report takes the longest?

In concrete terms, this means for the coming weeks:

1. Take stock of the tools and interfaces in use.
2. Clarify processes and requirements before selecting new software.
3. Start with the process that causes the most pain, usually time tracking.
4. Expand step by step as soon as the next management need arises.

If you take this route, you replace tool sprawl step by step with a data basis that can actually be used for management.
