Questions

What contractors ask before moving a work order.

Contact the billing team

Do we need to change how our client receives bills?

No. The bill package prints in your client's format. The bill room is an extra the client's engineer may use, free.

How long does it take to start a work order?

Send the BOQ in Excel. Our team imports it and sets up recoveries with you, usually in one call.

Can we start partway through a contract?

Yes. Import the up-to-date quantities from your last bill and the next bill continues from there.

Does it replace our accounting software?

No. Certified bills post to Tally Prime, Zoho Books or Busy. Tatha Vastu keeps the measurements and the bill.

Who can see a work order?

Only users you add to it. Site users see their sites, client users see the bills you share, and every change is logged.
