01Wenbru Software · Vaalpark, South Africa

Software, machinedfor the shop floor.

Wenbru builds the operating systems behind engineering workshops and service businesses: jobs, machines, tooling, stock, quotes, job cards, equipment history, invoices, audit trails. Designed in Vaalpark by a Red Seal turner who started writing code because the workshop needed it.

The premise

Most operational software is written by people who have never waited for a job card, hunted for a tool, or explained to a customer why the invoice is late.

Wenbru’s was not.
03Who we build for

Workshops that make and repair.

You know which machine is free before the planner does.

  • Machine shops
  • Pump, gearbox and rotating-equipment repair
  • Fabrication, fitting and assembly
  • In-house maintenance workshops

Every job, routedand visible.

  1. 01

    Job receipt

    Engineering captures the job with its number, priority and required-by date — even before the work physically arrives.

    ENQUIRY → EXPECTED JOB → RECEIVED

    Screen 01/05·Job page · Job Control · J310042
  2. 02

    Routing

    An ordered route of operations across workshops and areas, each stage stating what it needs: machine and operator, person only, or nothing.

    STANDARD ROUTE → JOB ROUTE

    Allocation

    The planning board orders per-machine queues; the assign screen offers only authorised, available operators and warns of double-booking.

    WAITING → ALLOCATED

    Shop-floor station

    Machinists start, pause with a reason, resume and complete their own work; the Tool Cupboard books tooling to the job in a few taps.

    TV board & ledger

    The wall board shows priorities, running machines and holds; every tool and insert is on the stock ledger, and every change on the audit trail.

The board on the wall is the same record on the desk.

Machines across the top, jobs on the cards, operators in custody, timers derived from events. Drag a job to another machine and watch the audit trail record it.

From the lead to the signedquote to the invoice.

  1. 01/ 05

    Lead

    Website quote requests, bookings and walk-ins arrive as records in a pipeline — NEW, CONTACTED, QUOTED, WON — not as e-mails.

    ENQUIRY → LEAD → QUOTE

  2. 02/ 05

    Quote, signed on site

    Build the quote in the office or on the customer’s premises; prices come from the catalogue; the customer signs on the technician’s phone or through a link.

    DRAFT → ISSUED → CLIENT SIGNED

  3. 03/ 05

    Job card

    The signed quote starts a job card with the lines copied in; the technician logs each unit serviced and captures the completion signature.

    SIGNED QUOTE → JOB CARD → APPROVED

  4. 04/ 05

    Equipment register

    One record per physical unit with serial, location, last and next service; every movement logged; due and overdue reminders sent to the customer.

    UNIT → SERVICE RECORD → NEXT DUE

  5. 05/ 05

    Invoice & PDF

    The invoice is built from the work actually done, on your letterhead with your banking details; payments, deposits and overdue accounts tracked.

    JOB CARD → TAX INVOICE → PAID

Each client runs on an isolated deployment — your data, your instance.

09Founder

A turner who learned to write software, not the other way round.

Michael Wentzel qualified as a Red Seal Turner and spent his working life at the machine before he wrote a line of production code. He knows what a foreman actually wants to see at 07:00: which job is on which machine, who has the boring bar, and why the P1 stopped.

Wenbru’s products come out of that. They are not generic business software with a workshop skin — they are built around the job card, the tool cupboard, the signed quote and the audit trail, because those are the objects the work is made of.

Wenbru builds products and configures them per client. That is how one small South African company can run software for an engineering workshop and a service business at the same time, and keep both honest.

“Software should hold tolerance too.”
