MatruOS for a pressure vessel and tank fabricator
Set up the way a pressure vessel and tank fabricator runs: made-to-order vessels, tanks and silos priced per kg of finished weight or lump sum per job; site erection of field tanks; modification and re-rating jobs; small spares (manholes, nozzles, dish ends). Routines, workflows, registers, licences and an AI team that knows the work are ready when you sign up.

What this solves
What a pressure vessel and tank fabricator deals with today, and what MatruOS sets up for it
Today
Offers are priced by weight only, so labour-heavy SS jobs lose money. The final 10% and PBGs sit unclaimed for months because the dossier is incomplete.
In MatruOS
MatruOS sets up 9 routines, 1 workflow, 3 registers and 10 licences for a pressure vessel and tank fabricator, with an AI team that reads your own records and prepares the work.
What changes
The right person is reminded at the right time, approvals wait for whoever decides, and every licence has a renewal reminder. Anything that sends, pays, signs, files or deletes waits for a person's approval.
Where you sit
MatruOS starts from how your business earns
Who you sell to, who you buy from, how credit moves and where you sit in the chain decide how your screens, reminders and reports are set up.
- Steel mill
- stockist
- fabricator
- EPC or plant owner (often through a consultant who sets the code and TPI)
Your suppliers
- Steel stockists (IS 2062, SA 516, SS 304/316L plates)
- Dish-end pressing shops
- Flange and forging makers
- Welding consumable dealers
- RT/NDT agencies and TPI firms
- Paint and blasting contractors
Credit and cash
Customers: 20-30% advance with PO, 60-70% against proforma before dispatch, 10% on commissioning or against a 10% PBG for 12-18 months. Suppliers: plates on 15-30 days or cash at a discount; NDT and TPI billed monthly
Plates are 55-65% of job cost and must be bought within a week of the order; the advance rarely covers them. Jobs take 6-16 weeks, so 2-3 months of working capital is tied up per job, plus bank guarantees against the limit
