Project Controlling Software: 6 Systems Compared on Margin

If you sell projects, you earn your money between the proposal and the post-calculation. In many consultancies, IT service providers and engineering firms, exactly this area still lives in a spreadsheet: one file per project, hours transferred by hand, and the analysis finished when the project is long over. Project controlling software is meant to close this gap.

The pressure comes from outside. The 25 leading mid-sized IT consultancies in Germany grew by an average of 1.9 percent in 2025, after more than ten percent a year between 2015 and 2023. Among the 20 German management consultancies with the highest revenue, growth in 2025 was 4.1 percent, after 7.5 percent the year before, and average revenue per head declined. Where growth no longer carries the result, the margin per project has to.

Economically, this costs money in three places. First, project management loses reaction time: a budget that was blown in October shows up in the report on 10 November, and by then the change order can no longer be negotiated. Second, the staffing mix stays invisible: seniority that the proposal does not cover only becomes apparent in the annual review. Third, the next proposal is calculated on unreliable data, because the post-calculation for the last comparable project was never done.

Project controlling software closes this gap by bringing booked hours, budgets, hourly rates and costs together in one system. This comparison looks at six systems that regularly make the shortlist for consultancies and service providers in Germany, Austria and Switzerland, and names the criteria on which the decision actually depends.

Key points at a glance

At project level, a single question decides the benefit: are the figures created where the work happens?

• Revenue and costs per project only answer the question of profitability when they come from the booked hours.
• Billable and non-billable hours must be separated at the time of booking, because an estimate after the fact makes utilization look better than it is.
• A budget warning has an effect, a budget report only documents. On fixed-price projects, the difference between the two is several thousand euros.
• Post-calculation is the learning tool of the project business, and it gets skipped as soon as it requires an export.
• The price range of the systems compared runs from under €10 to over €60 per user per month, depending on the billing unit, module scope and implementation.

Seven criteria that decide project controlling software

Project controlling is more than a report at the end of the month. Seven requirements decide whether a system holds up in day-to-day work.

1. Revenue and costs per project

The question "Are we making money on this project?" can only be answered if revenue and costs sit at the same level. A project can be on schedule and still make a loss, because too many hours were booked to it by too-expensive people. What matters is that the valuation works with an internal cost rate per person. Without this rate, every margin analysis remains a revenue analysis.

2. Analysis per employee

The view per person shows where seniority is being burned. It also answers the question that comes up in every staffing meeting: who is really fully utilized across several engagements, and who is carrying work that nobody pays for? Check whether the analysis per person goes down to costs and revenue or stops at hours.

3. Billable and non-billable hours

In professional services, not every hour worked is an hour sold. Travel time, rework after a complaint, internal coordination, presales: all of this occurs in the project and does not appear on the invoice. If you lump both together, utilization looks better than it is and the project margin comes as a surprise. What matters is that the separation happens at the time of booking.

4. Budget warning at a threshold

A report that shows on the 10th of the following month that the budget was blown in the previous month changes nothing. What helps is a notification when a threshold is crossed, while there is still room to act: negotiate a change order, restaff the team, sharpen the scope. Check two details: can the threshold be set per project, and does the notification reach the project manager or only the controller?

5. Post-calculation against the original calculation

Post-calculation compares the calculated proposal with the work actually delivered. Only when several projects of the same type have been post-calculated can the next proposal be calculated reliably. It is important that it works without a data export and uses the same structure as the calculation. As soon as an export is needed, post-calculation stops happening in practice.

6. Fixed price and time and materials billing

Most professional services firms work with both models, often within the same project: concept phase at a fixed price, implementation on a time and materials basis, change requests separately. Software that only handles one of the models cleanly forces side calculations. For fixed price, the system has to set progress against the budget; for time and materials, it has to show the billable balance.

7. Booking hours in the same system

The honest benchmark is whether the spreadsheet disappears afterwards. That works when the data is created where the work happens. Every solution that has to import hours from another system creates an extra interface and an extra source of errors.

The six systems compared

All information comes from the vendors' own websites, retrieved on 21 October 2026. Where a vendor does not list a feature on its product pages, the table says "not listed". This is not a statement about whether the feature exists.

What the table says about the systems

ZEP Control is the line for Project Management with a commercial view. Everything from ZEP Track is included, plus Work Items, Project Planning and Revenue & Costs. Proposals and Invoicing are part of ZEP Operations. More on this below.

teamspace includes controlling from the office edition, including contribution margin per project and per client and post-calculation per order. However, the licence price only reflects part of the cost, as hosting and support are charged separately.

Projektron BCS offers the greatest methodological depth, from earned value analysis to milestone trend analysis, and reports impending budget overruns by email. The lean edition BCS.light does without earned value and proposal calculation.

PACS is built consistently around project controlling and is the only system in the comparison that lists multi-level contribution margin accounting for projects and employees. The scope is defined via modules, and booking hours is one of them.

Vertec covers a broad range from time and service recording through budgeting to invoicing, and handles fixed prices and time and materials billing in the same system. Post-calculation is listed as a feature of its own. The entry price is well above the rest of the field, but drops sharply from the eleventh user.

Clockodo is the cheapest entry point and separates billable from non-billable hours cleanly. Invoices are created in connected systems, and the vendor does not list contribution margin accounting.

Prices compared: three factors distort the picture

Price comparisons in project controlling are rarely as clear-cut as list prices suggest.

First, the billing basis. Projektron BCS licenses by users who log in within 24 hours, so people who are rarely involved share a licence. teamspace charges per activated user and does not charge for employees who have left. For teams with many part-time staff, both models produce a noticeably different annual total than a licence per head.

Second, the module scope. With Vertec, the base package costs €46 per user per month, and budgeting and controlling are added at €15.50 each; from the eleventh user, all three items drop significantly. With Clockodo, the budget warning is in the higher tier. The entry price therefore says little about the price of the configuration you actually need.

Third, operation and implementation. teamspace lists hosting from €10 per month, standard hosting at €100 per month plus €750 setup, and puts an implementation with data migration and training at around €5,000. Projektron BCS.light ties you in for six months under the rental model. PACS does not publish a list price and determines the price via a configurator. If you only compare licence prices side by side, you are comparing three different types of cost.

A reliable calculation only emerges when licence, operation, implementation and minimum term are set side by side over three years. How this total compares with the cost of the status quo is shown by weighing margin loss against reporting effort.

Which system suits which company

The classification follows the maturity of the project business, not the length of the feature list.

Up to around ten employees with a manageable number of projects, a system that books hours cleanly to clients and projects and keeps budgets visible is often enough. Clockodo covers this need at the lowest price, but requires the higher tier for budget warnings and passes invoices on to a connected system.

Growing service providers with several parallel projects need planning and commercial analysis in one logic. Here, ZEP Control and teamspace office are close to each other, with an identical annual price per user. The difference lies in the scope: teamspace includes billing and CRM in its entry edition and charges hosting separately, while ZEP bundles billing in the next line and includes hosting and integrations at no extra cost.

Organisations with high methodological demands, for example earned value, milestone trend analysis or multi-project controlling, will find this depth in Projektron BCS. The effort for setup and maintenance rises accordingly.

Firms that think from a controlling perspective, such as management consultancies with a pronounced contribution margin logic per level, will find in PACS and Vertec systems built for exactly that. Both require a configuration decision before the start, and Vertec also a team size at which the tiered pricing pays off.

Where the switch fails in everyday work

The selection has less influence on success than the first eight weeks afterwards. Three patterns keep repeating.

The spreadsheet lives on. As long as a single report only exists in Excel, someone maintains both versions. After three months, the file is the truth again. A clear rule helps: every figure shown in the monthly meeting comes from the system.

Bookings come in too late. A controlling setup that waits for last week's hours reports budget overruns too late. Reminders about missing bookings and booking that works on mobile devices matter more here than any KPI.

The internal cost rate is missing. Without a stored cost rate per person, every margin analysis stays empty. teamspace names exactly this as the most common cause of empty contribution margins. This rate belongs in the first week of setup, with a validity date, so that later salary adjustments do not change the past.

Then there is the question of acceptance. A booking that takes three clicks and a search gets reconstructed on Friday afternoon. That is exactly when the data is created that nobody later accepts as a basis for decisions.

Project controlling with ZEP Control

ZEP Control is the product line for Project Management with a commercial view. Planning happens in the same system in which the team books its hours to clients and projects, and revenue, costs and utilization are derived from the same bookings. It includes Work Items, Project Planning and Revenue & Costs, plus everything from ZEP Track: working time and project time tracking, project and client management, Absences & Overtime, Locations & Departments and the export to payroll.

Three points are relevant for the comparison. The ZEP Assistant, ZEP Pulse and ZEP MCP are included at no extra cost; ZEP Pulse suggests project hours from your own working day and the user confirms them. All integrations are included without limit in every line, ZEP's own as well as single sign-on and third-party ones. Three add-ons are available: Resource Planning for €5, Ticketing System for €4 and ZEP Terminal for €15, each without an annual discount.

We name the upper limit ourselves. ZEP Control stops short of document and receipt management. Proposals, Invoicing, Travel Expense Management and the export to project-specific financial accounting belong to ZEP Operations, from €29 on an annual contract and €35 monthly. If you want to set the post-calculation against your own proposal or invoice directly from the work delivered, this is the line for you. If you want to steer today and bill tomorrow, you can switch later without moving your data.

Conclusion

Before you choose, check three things in your own figures. First: how many working days a year go into compiling the monthly report? This figure is the most honest benchmark for any licence price. Second: how many projects from the last twelve months have you post-calculated? If the answer is less than a third, the problem is the effort, not the will. Third: when did you last learn about a budget overrun while there was still room to act?

Then take your actual configuration into the request: number of users, modules required, hosting, implementation and minimum term over three years. And bring the same report that someone currently builds by hand to every demo. The system that delivers it from your own bookings makes the shortlist.
