Questions
What government works contractors ask before they move a work order.
Does it replace the engineer-in-charge's MB?
No. Where the contract requires the department's own measurement book, Tatha Vastu is your record of the same measurements, with photos and dates, to check the MB against.
Which department formats are built in?
CPWD and state PWD formats. For a railway, highway, water or municipal format, send one past bill and we build it during onboarding.
Does it work out GST TDS and labour cess?
Yes, at the rates you set for each work order. Tatha Vastu computes and records them; filing returns stays with your accountant.
Can it work out price variation?
Yes, where the agreement has an index formula, commonly known as clause 10CC in CPWD contracts. You enter the base and current indices for each bill.
Can an auditor see last year's bills?
Yes. Every bill, measurement and change is kept with the user and time. Closed work orders move to a read-only archive at no charge.
