teamspace

Software for architects and engineering practices: from the HOAI fee to the final invoice.

Architecture and engineering practices bill by a fee table set out in law. teamspace runs the fee table, the hours on the work phases and the billing in one place, without transferring the fee by hand from Excel into the invoice.

Light teamspace card headed 'From design to margin'. On the left, the view of a residential building under construction at a scale of 1:100 with three finished storeys, a shell-construction storey in scaffolding and a tower crane, plus an orange height dimension of 12.80 m. On the right, a teamspace card for the residential building project floats with work phase 5 running, a plan-vs-actual bar and the status 'on plan'.

More than a calculator

What sets HOAI software apart from a fee calculator.

A HOAI calculator gives you the number. There are three things it does not do that matter in the day-to-day of the office.

The table calculates, you transfer nothing

Enter the fee zone, eligible costs and refurbishment surcharge, the fee table per HOAI 2021 calculates work phases 1 to 9 and writes them as invoice line items. No retyping from an Excel table.

Hours land on the work phase

Staff log their time directly on LP 5 or LP 8, in the office and on site. Plan-vs-actual per phase grows out of these entries, without the parallel time list alongside.

The margin stays visible before the engagement closes

Contribution margin and post-calculation per phase and per engagement, with travel costs and third-party costs offset. You see the profitability while there is still something to adjust.

HOAI fee

Calculate your fee in 30 seconds.

Enter the fee zone, eligible costs and work phases, the HOAI calculator estimates the fee. In the software it becomes, with one click, the project that the hours log to and that the billing emerges from.

To the HOAI calculator

The HOAI fee

The HOAI fee is the basis: the profitability arises beyond it.

The basic fee results from the fee zone, eligible costs and the commissioned work phases. The change orders and special services, however, decide the project's success: whoever spots them early, documents them cleanly and bills them consistently secures additional fee. teamspace runs them with their own plan-vs-actual trail, so the margin picture of the basic engagement is preserved.

Change orders

Spotting change orders in time, documenting and billing them cleanly.

In nearly every project additional services arise, whether through the client's change requests, new requirements or changed conditions. For these to become billable fee, change orders have to be spotted in time, documented traceably and cleanly separated from the basic engagement.

  • Change order with justification, effort and fee, including documented approval by the client.
  • Separate plan-vs-actual analysis for change orders and special services, so the profitability of the basic engagement stays transparent.
  • Refurbishment surcharges and ancillary costs as their own line items, clearly shown and traceable at any time.

teamspace supports exactly these processes without extra effort, so no billable service gets lost.

To project controlling

Hours on the phase

Every hour belongs to a work phase.

Only on the work phase does an hour become economically analysable. From the accepted fee proposal, a project is created with one click, the work phases stand as work packages, fee shares and budgets are carried over. Your staff log their hours directly onto them.

  • Logging on the phase or the work package, with an hourly rate per person and role, in the browser and in the app.
  • Plan-vs-actual per work phase emerges live from the logged hours, not only in the quarterly report.
  • Activating or excluding phases, for example when LP 8 site supervision is awarded externally.

This way it is visible at any time which work phases are on plan and where adjustment is needed.

To time tracking

The path of a building project

From preliminary design to final invoice.

One continuous path, without transferring between HOAI table, time list and accounting: the fee proposal becomes the project, the logged hours become the billing.

  1. 1

    Set up the project per HOAI

    Record the fee zone and eligible costs, the fee table calculates the work phases. Activate or exclude phases, depending on the engagement.

  2. 2

    Capture hours and travel costs

    Staff log their time on the relevant work phase. Site-management drives to the kilometre, receipts attached by photo.

  3. 3

    Track plan-vs-actual per phase

    Per work phase and per work package the dashboard shows planned hours, actual hours and contribution margin, up to date daily.

  4. 4

    Down payments at phase completion

    On reaching a phase completion, the down payment invoice is created per the phase share, with a security retention where agreed.

  5. 5

    HOAI-compliant final invoice

    The final invoice offsets all down payments, shows change orders separately and goes to the client as ZUGFeRD or XRechnung.

Start

Ready to go in a few days.

We take over master and project data from Excel, including a one-off structuring of your HOAI engagements, fee tables and hourly rates. The basic setup takes a few days, a dedicated process consultant accompanies you up to go-live.

Profitability

Project profitability in view at any time.

Many planning practices only know after a project closes whether an engagement was profitable. By then it is too late for corrections. teamspace makes the margin visible while the project is still running.

  • Plan-vs-actual per work phase, contribution margin and post-calculation per project, up to date daily.
  • Budget consumption and fee status across all projects at a glance.
  • Spotting deviations early and adjusting, before they affect the margin.

This turns gut feeling into a sound basis for your decisions.

To project controlling

Site supervision on location

Everything that arises on the building site belongs directly to the project.

During site supervision, travel costs, receipts, documentation and third-party costs arise continuously. In teamspace each of these hangs on the building project, not in a collected expense claim at year end or a separate notebook.

  • Travel costs to the kilometre or as a flat rate, captured and assigned directly to the project, receipt by photo via the installable web app.
  • Site diary with photos, tasks and a link to the work phase, documented centrally on the project, retained in audit-proof form in GoBD mode.
  • Third-party costs and disbursements, for example for expert reports or statics, managed directly in the project.

This keeps costs, documentation and project information complete and traceable in one place at all times.

To travel expense accounting

“We mostly work with the budget column.”

Over a building project that drags on for years, the office management only keeps the overview if every work phase carries its plan-vs-actual status. teamspace runs exactly this trail.

Three focuses

Architecture, engineering and planning practices.

Three profiles, three focuses. teamspace fits all three, with their respective workflows.

Architecture practices

Architecture practices work phase-oriented, often on several building projects in parallel. Beyond design quality, the clean assignment of services, times and fees decides the commercial success.

Braucht besonders

  • Run projects structured along the work phases
  • Document delivered services traceably
  • Bill fees transparently and securely
  • Project progress, budgets and open services in view

teamspace runs building projects structured by work phases, captures times cleanly and bills services traceably, as a continuous basis for steering, records and fee.

Engineering practices

Engineering practices work on technically complex projects with many parties, long durations and high demands on documentation. Profitability here arises above all from clean planning and reliable figures.

Braucht besonders

  • Transparency over effort, costs and profitability
  • Structured collaboration in interdisciplinary teams
  • Reliable figures for controlling and post-calculation
  • Clear records for clients and internal steering

teamspace creates a central basis for projects, times and billing. Engineering practices see project status, utilisation and profitability at any time, without laborious analyses by hand.

Planning practices

Planning practices coordinate several specialist disciplines and project parties. The effort for coordination and billing grows with every interface, especially when the information is spread across different systems.

Braucht besonders

  • Central overview of all projects and parties
  • Clear steering of tasks, times and responsibility
  • One data foundation for steering and billing
  • Less coordination, more planning certainty

teamspace bundles steering, time tracking and billing in one system. This way planning practices keep the overview even with many parties and steer projects profitably.

Public-sector clients

Creating XRechnungen without extra effort.

Whoever works for municipalities, federal states or federal agencies has to meet the requirements for electronic invoices reliably. In teamspace the XRechnung emerges directly from the engagement, without a separate administrative process.

  • XRechnung with routing ID and all mandatory details, created directly from the engagement.
  • Preview of the finished document before dispatch.
  • Hand-over via the prescribed route, for example Peppol or the client's invoice receiving portal.
  • ZUGFeRD for private clients, as a PDF with embedded data record.

This way public-sector and private clients can be served with the respective fitting invoice formats.

Why teamspace

What stands behind the software.

Since 1999 from Darmstadt

We have been developing teamspace since 1999 in Darmstadt, self-financed and without outside capital, specialised in software for project-based professional services firms.

One system from the table to the invoice

From the fee proposal through the hour on the work phase to the final invoice, everything runs on one base. No HOAI sheet alongside.

Personal service

Experienced process consultants accompany you from the first requirements to go-live, with German support that knows your billing.

What software for architects and engineers must be able to do

HOAI software runs the fee, hours and billing on one data foundation.

Software for architecture and engineering practices, often called architect software, office software for planning practices or HOAI software, is an application that runs the HOAI fee, the hours on the work phases and the fee invoice on one data foundation, so the fee does not have to be transferred by hand from a table into the invoice. The fee emerges from the fee zone and eligible costs across work phases 1 to 9, the client pays in down payments, and the final invoice offsets everything.

The margin is decided not by the basic services but by the change orders and special services that arise during the work. Software for the planning practice runs them with their own plan-vs-actual trail, separated from the basic engagement, so the margin picture is preserved. teamspace is not pure accounting here, but the ERP for architecture and engineering practices that runs the building project, from the fee table to the paid invoice.

For every kind of practice

Building, structural, MEP and infrastructure, all bill by HOAI.

In the end there is everywhere the fee table, the work phase and the clean billing. teamspace adapts to the kind of planning you do.

Architecture practices Building, residential construction and refurbishment over work phases 1 to 9.
Structural planning Statics and building physics with their own fee tables, plan-vs-actual per construction section.
Engineering practices MEP Heating, ventilation, sanitary and electrical as multi-discipline from one data base.
Site supervision and project steering Site monitoring with travel days, site diary and schedules on the project.
Interior and landscape architecture Their own fee tables, material costs as disbursements, site supervision with photo.
Civil engineering, infrastructure and surveyors Phase model for civil engineering, experts with a flat-rate or hourly fee.

Terms

Six terms from the HOAI day-to-day.

Terms that come up again and again in the fee.

Work phase
The HOAI divides the planning into nine work phases, from the basic appraisal to the building supervision. Each phase carries a percentage fee share. In teamspace the phases stand as work packages that are logged to and billed.
Fee zone
The HOAI assigns each project, by difficulty, to one of five fee zones, from I to V. Together with the eligible costs, the zone determines the fee from the table.
Eligible costs
The costs of the structure that underlie the fee calculation. From them and the fee zone, the fee table reads the basic fee.
Refurbishment surcharge
A percentage surcharge on the fee for conversions and modernisations. In teamspace a separate percentage line item, shown separately from the basic fee.
Down payment invoice
An interim invoice at phase completion, with the corresponding fee share. The final invoice offsets all down payments at the end.
Special services
Services beyond the basic services of the HOAI, freely agreed. In teamspace run with their own plan-vs-actual trail, so the margin of the basic engagement stays visible.

An honest assessment

Which practices teamspace fits, and which it does not.

Fits less well

  • Building contractors with materials management, warehouse and production.
  • General contractors with bill-of-materials and inventory management.
  • Practices that only want accounting without project and fee management.
  • Planning without hourly, flat-rate or HOAI billing.
Recommended

Fits well

  • Architecture, engineering and planning practices that bill by HOAI.
  • Practices with work phases, down payment invoices and change orders separated from the basic fee.
  • Multi-discipline projects from architecture, structural and MEP, with travel costs and site diary.
  • Practices from a small team to several hundred staff.

Frequently asked questions on software for architects and engineers

What is architect software?
Architect software is an application that runs the HOAI fee, the hours on the work phases and the fee invoice of an architecture or engineering practice on one data foundation. teamspace calculates the fee from the fee zone and eligible costs, logs hours directly on the work phase and creates down payment and final invoices, with change orders separated from the basic fee.
What is HOAI software?
HOAI software holds the fee tables under HOAI 2021, calculates the fee from the fee zone and eligible costs across work phases 1 to 9, and turns that into the down payment and final invoices. teamspace combines this HOAI calculation with time tracking on the work phase and project controlling, so the fee does not have to be transferred by hand from a table into the invoice.
Does teamspace support HOAI 2021?
Yes. Fee tables per HOAI 2021 are stored, fee zones I to V, eligible costs and refurbishment surcharges can be configured. Per engagement the logic can be adjusted if special rules apply. More on this in the HOAI calculator.
How does time tracking work per work phase?
Staff log hours directly on the relevant work phase. Plan-vs-actual per phase and per work package updates continuously. More on time tracking and project hours.
Can we run site supervision and the site diary in the same system?
Yes. The project documentation runs site diaries, minutes, photos and schedules directly on the project. The installable web app is suited to site supervision on location, with an active connection.
How do down payment invoices work?
On reaching a phase completion, for example after LP 4, a down payment invoice is created with the corresponding phase share. A security retention can be run as its own line item. The final invoice offsets all down payments at the end.
Can we run multiple disciplines in one engagement?
Yes. A building project with architecture, structural and MEP runs as one engagement with several fee tables, each discipline with its own phases and its own final invoice. More on multi-project management software.
How does teamspace handle public-sector clients?
Public-sector clients require the XRechnung. teamspace creates it in the standard format with a routing ID, dispatch runs via Peppol or to the client's invoice receiving point. More on e-invoicing.
How are change orders and special services mapped?
Change orders and special services are captured separately from the basic fee, documented per engagement and shown cleanly separated in plan-vs-actual, contribution margin and the final invoice. This way the commercial effect stays visible and evidenced.
Where is data stored?
All data is processed in an ISO-27001-certified data centre in Frankfurt am Main, exclusively in the EU. Certified is the data centre, not teamspace itself. The contracting party is 5 POINT AG, headquartered in Darmstadt; approved documents stay retained in audit-proof form in GoBD mode.
Can existing project data be taken over from Excel?
Yes. Master and project data can be imported from Excel or other sources. On request the customer success team takes over the migration, including a one-off structuring of your HOAI engagements, fee tables and hourly rates.
How quickly can a practice start with teamspace?
The basic setup with HOAI templates, staff, hourly rates and first engagements takes a few days. Workshops, a guided pilot phase and a dedicated process consultant up to go-live are part of the onboarding.
Is teamspace also suitable for small architecture practices?
Yes. teamspace scales from the one-person practice to several locations. Small practices typically start with project management, time tracking and invoicing software and add CRM or the digital employee record later, without data migration.
Which analyses do owners and project managers see?
Dashboards show project status, utilisation and profitability up to date daily. Per work phase a plan-vs-actual comparison, contribution margin and post-calculation appear, per staff member the utilisation across the engagements. More on project controlling.
