Job costing for the trades, installation and manufacturingKnow which jobs pay off.
In 30 days.

Your team clocks onto the job with a scan, on a phone on site or on a tablet in the workshop. Nobody in the office types up timesheets any more, and you see live on each project how many of the estimated hours have been used. We set everything up in 30 days and support you for three months.

Built on ERPNext, the open-source ERP. Quotes, purchasing, stock and invoicing can follow later.

The problem

You only find out whether a job paid off once it is over.

Monday in the office: last week’s timesheets are on the desk, some illegible, some missing. Then the typing starts.

Paper chaos

Timesheets come back late, incomplete or not at all. Anyone who can no longer remember Monday by Friday makes a guess.

Double work in the office

Every hour is copied into the system by hand. That costs time every week, and every typo ends up on the invoice.

Flying blind on margins

Whether a job stays on budget only shows after the final invoice. By then nothing can be changed, and the next estimate is based on gut feeling again.

The solution

Record time where it happens.

At the machine, at the welding bay, on site. With Nachkalkulation Plus, our own app for ERPNext, you save time in the office and see early where a job is costing you money.

Save time

Scan instead of writing.

Scan the ID badge, scan the job sheet, choose the task. That works on a shared tablet in the workshop or on a phone on site, with no training. The times go straight into ERPNext’s timesheets; the office only checks and posts them.

  • A phone or tablet camera is enough, a hand scanner is optional
  • Without signal, clocking continues and syncs later
  • Scanning another job switches over automatically
Time clock on a tablet: scan your ID badge, list of employees and who is working on which job

See the margin while you can still act.

You estimate the hours per work step. On each project you see live how much has been used, and the report shows every open job down to the single step. From the times and your cost rates, ERPNext calculates the labour cost per project.

  • Traffic light per task: green below 80 %, orange up to 100 %, red above
  • Planned, actual and remaining hours for every job at a glance
  • If welding regularly takes longer than planned, your next estimate gets more accurate

The roadmap

From timesheets to your first report in 30 days.

Not a project that drags on for months. You see progress every week.

  1. Right away

    Agreement on the call

    While we are still on the call, you get access to our customer portal. There you fill in the questionnaires: company details, employee list and roles.

  2. Day 1

    Kick-off

    60 minutes live: we agree on processes, tasks and the layout of your job sheet. You get access to the video academy. This is where the 30 days start.

  3. Week 1

    Your first job sheet

    The first job sheet with your layout and barcode is ready as a PDF for your feedback.

  4. Week 2

    Your system is ready

    We hand over your configured ERPNext with user accounts, permission groups and print layouts.

  5. Week 3

    First scan in your business

    Joint go-live session: your team gets the app on their phones, and the first employee clocks onto a job live.

  6. Day 30

    First report

    The first job costing for a real project is in your dashboard.

  7. To week 12

    Support in everyday work

    Feedback call after six weeks, review call after twelve. Whatever is not yet running smoothly, we improve.

What is included

Everything for the first 30 days and beyond.

We set up the system for you; you provide the details about your business. Setup is a one-off fixed price; hosting, updates and the customer portal are a fixed monthly fee. We give you the figures on the call.

Setup

  • ERPNext configured: users, permission groups, projects and tasks
  • Nachkalkulation Plus with a time clock for phones and tablets
  • Job sheets and employee ID badges as print layouts with barcodes
  • Customer portal with questionnaires, tickets, invoices and video academy
  • Explainer videos on the app for your team

Three months of support

  • Support via our ticket system
  • Fixed phone hours for questions in between
  • Four live sessions: kick-off, go-live, after six and after twelve weeks
  • Improvements wherever things are not yet running smoothly

Our promise

Your team needs no training.

The time clock app is built so that your employees can use it without training. If someone still struggles with it after the rollout is complete, we keep supporting you free of charge until they are comfortable with it.

The promise covers your employees’ use of the app.

Who is behind it

You talk directly to the person who builds your system.

Til Wiggers · Founder of openBlueprint, software developer

I am Til Wiggers, founder of openBlueprint. We build business systems on open source for manufacturing and the trades, systems you own and that fit the way you work. I use ERPNext, Frappe CRM and Frappe Learning myself every day.

  • I am your contact from the first call to the running system, with no sales team in between.
  • What we discuss in the call is what we build. Nothing gets lost between consulting and development.
  • We work remotely, with on-site visits by arrangement. In English or German.

What comes next?

The first area. Not the last.

Job costing runs on ERPNext, a complete ERP, meaning the central software for orders, stock and accounting. If you want, your system grows with you. But you do not have to.

Expand step by step

Quotes, purchasing, stock and invoicing come in when you are ready. No big switchover project is needed.

One database

Times, projects, materials and invoices work together. Nothing is maintained twice or reconciled between programs.

Built on open source

ERPNext is open source, so there are no per-user licence fees for the ERP. Your recorded times sit in ERPNext’s standard timesheets.

Frequently asked questions

What businesses ask us before they start.

How much effort is it for us during the 30 days?

Before the start, you fill in questionnaires on company details, employees and roles in the customer portal. After that, we mainly need you for the kick-off (60 minutes), your feedback on the job sheet draft and the go-live. We take care of the setup in the system.

We do not use ERPNext yet. Is that a problem?

No. We set up ERPNext for you within the 30 days. For job costing, projects, employees and timesheets are all you need. Purchasing, stock or accounting can follow later, but they do not have to.

Not all of our fitters have a work phone. Does it still work?

Yes. At the shared tablet in the workshop, everyone signs in with their ID badge or taps their name. Only those who should work with a personal account need their own phone.

What happens on site without signal?

Clocking continues. The device stores every scan with its time and sends it as soon as there is a connection again.

Do we need special hardware?

No. The camera of a phone or tablet reads the codes. If you want to scan faster, you can connect a standard hand scanner. You print the ID badges and job sheets yourself.

Does it cover legal working-time recording?

That is not what it is built for. Nachkalkulation Plus records how long people worked on which job. Start and end of work, breaks and holidays belong in a working-time system. Please check with your accountant or trade association which records your business needs.

What happens after the three months?

Hosting, updates and the customer portal continue for the monthly fee. In the review call after twelve weeks, we look at the results together and at whether another area makes sense next, and which one.

What does it cost?

Setup is a one-off fixed price; hosting, updates and the customer portal are a fixed monthly fee. We give you the figures in a 15-minute call, together with an honest view on whether job costing suits your business.

No-obligation call

In 15 minutes you will know whether it fits.

We look together at how you record and estimate times today. Afterwards you know whether job costing suits your business and what it costs. Free, without obligation and without preparation.
