Engineering changes miss procurement
A revised drawing changes quantities, but purchase requirements and budgets remain unchanged.
EPC ERP software for contractors
Control project cost, procurement, site progress and billing—from one system
Connect BOQ, budgets, engineering changes, procurement, materials, subcontractors, site execution and client billing. Identify delays, cost overruns and billing gaps before they affect project margin.

The daily disconnect
Where EPC projects lose time, money and visibility
Small record gaps become procurement delays, cost surprises and slower cash flow.
Buying lacks cost context
Teams raise PRs and POs without seeing the approved BOQ, committed cost or remaining budget.
Progress and consumption diverge
Reported progress is difficult to reconcile with materials, labour and actual project expenses.
Completed work stays unbilled
Measurements, evidence or approvals remain pending, delaying RA bills and project cash flow.
Supista connects these records using the same project, WBS, package, BOQ line and cost head.
Connected EPC lifecycle
Follow every commitment from engineering to margin
Every stage retains the project context needed by the next team.

Lois AI inside the ERP
Ask Lois to find the problem—or prepare the next step
Move from a question to an authorised ERP action without losing the control of your existing process.
Find
“Which materials may delay work during the next 14 days?”
Compare
“Compare the quotations received for the cable package.”
Prepare
“Create a PR for the approved electrical BOQ items.”
Find
“Which projects have exceeded their procurement budget?”
Compare
“Show completed quantities that have not been billed.”
Prepare
“Prepare today’s DPR from these site updates and photographs.”
Find
“Which vendor deliveries are overdue?”
Compare
“Summarise margin movement across all active projects.”
Human approval stays in control. Lois works only with authorised records, previews important actions and follows your existing approval matrix.

Representative EPC workflow
Replace disconnected handoffs with one project view
This example describes the configured workflow, not a claimed customer result.
BOQs, procurement and site reports are maintained separately.
PRs, orders, receipts, progress and bills link to the same project structure.
Management can identify pending procurement and billing gaps from one project view.
Configuration and implementation
Configured around your EPC operating process
Retain your formats, approval logic and company terminology while standardising the data underneath.
Import existing BOQ, WBS and vendor masters
Configure cost heads and project packages
Recreate approval matrices and financial limits
Configure DPR, measurement and billing formats
Assign project-wise and role-wise access
Integrate existing accounting or ERP systems
Build company-specific dashboards
