Deviation & variation statements, done digitally
Deviation Statement Software for Railway & PWD Contractors
Stop rebuilding deviation statements in Excel before every bill. PRIME ERP keeps agreement quantities, executed measurements and rates in one place, and produces item-wise deviation statements, variation statements and revised estimates whenever you need them.
Item-wise deviation statements: agreement quantity vs executed quantity with amounts
Works with USSOR, DSR and non-schedule (NS) items
Variation statements for scope additions and substitutions
Revised estimates with sub-works and item-level detail
Measurements recorded once, reused across statements and bills
PDF outputs ready for submission to the department
How it works in PRIME ERP
Set up the agreement
Load your work order with schedule items, agreement quantities and rates — from USSOR/DSR masters or Excel import.
Record executed quantities
Site engineers record work order measurements as work progresses; everything stays item-linked.
Generate the statement
PRIME compares agreement vs executed item by item and produces the deviation statement as a clean PDF.
Frequently asked questions
What is a deviation statement?
A deviation statement compares the quantities in the original agreement against the quantities actually executed, item by item, showing excess and savings. Departments typically require it before passing running or final bills when quantities deviate from the agreement.
Does PRIME ERP support both railway (USSOR) and CPWD/PWD (DSR) work?
Yes. PRIME ERP maintains both USSOR and DSR item masters with Excel import, and deviation statements work the same way for either schedule.
Can my site engineers enter measurements from the field?
Yes. PRIME ERP is a web app that works on any phone or tablet, with role-based access so site engineers can record measurements and progress without seeing financial data.
What other statements can it produce?
Variation statements, revised estimates with sub-works, work order measurement records, and 30+ financial and project reports — all as PDFs.
Run your contracts on one platform
PRIME ERP is built around the real workflows of railway and government civil contractors — schedule-rate billing, measurements, deviation statements, labour compliance, and the money trail behind them. Start a free trial, import your data, and see your project the way the department sees it.
