Maintenance that lives on paper and in people's heads
Breakdowns repeat
Repairs are noted on paper or not at all, so nobody sees that the same press failed three times this year.
Preventive tasks slip
Filter changes and lubrication depend on someone remembering the date. Until the machine stops.
Parts run out
You discover the seal kit is out of stock when the line is already down and waiting.
Seven tabs. One maintenance system.
Each tab does one job and feeds the dashboard. You type in the cream cells, the formulas do the rest.
Start
Six-step setup, colour code and KPI definitions.
Dashboard
Open jobs, overdue PM, MTTR, MTBF, availability, top 10 downtime.

When a spreadsheet is the right tool
Mini-GMAO suits workshops and small plants that want structure without a software project. If you need a mobile app for every technician, a full CMMS is the better choice.

Questions before you buy
Which Excel versions does it work with?
Excel 2010 and later on Windows and Mac, Excel online and Google Sheets (File › Import). It uses no macros, so it opens without security warnings.
Can I add my own machine types, locations and technicians?
Yes. All dropdown lists are edited in the Settings tab.
How many machines can I track?
300 rows per register: assets, preventive tasks, work orders and spare parts. You can extend it by copying the last row.
How are MTTR, MTBF and availability calculated?
From the breakdown work orders in the analysis period you choose. The formulas are explained in the Start tab and in the PDF guide.
Can I use it on several sites?
The standard licence covers one site. Choose the 5-site licence if you run several plants.
What if it isn't right for me?
Email us within 14 days and tell us what didn't work. We'll help you set it up or refund you.
