Questions
What MEP subcontractors ask before they move a project onto Tatha Vastu.
Can I bill in the main contractor's format?
Yes. Send one past bill in their format and we set it up during onboarding.
How are lump-sum items like testing billed?
As a percentage complete against the item, recorded by your engineer with a note and photos.
Can I see the margin on each item?
Yes. Your rate, the labour contractor's rate and the executed quantity give the margin per item and per bill.
What about material I issue to labour contractors?
Enter it once against the labour contractor. It is recovered on the bill it was used in, at the rate you set.
Which plan has back-to-back billing?
Back-to-back subcontractor billing is in the Enterprise plan, with custom formats and a named onboarding engineer.
