Write to us for help

If something is not clear, or a screen shows a message that this guide does not explain, write to us by email. A good mail has your mobile number, the tender or the item you were on, what you pressed, and a photo of the screen, and we reply by email.

What to put in the email

  1. Write to admin@revenin.com.
  2. Put your mobile number, the one you sign in with, so we can find your account.
  3. Put the tender if it is ContractBill, or the item if it is RateAnalyser, with its name or its code.
  4. Say what you pressed, and what you saw after that.
  5. Add a photo of the screen, with the message on it. A photo from your phone is fine.

For example:

Subject: Download refused, Drain work, Shakurbasti. My mobile number is (your 10 digit number). I pressed Bill in Excel on the tender Drain work, Shakurbasti, and the Download page says the bill is paid for a different work. It is the same work and I only corrected the quantities. A photo of the screen is attached.

The Download page strip that says a paid bill is a different work, with the Write to us button
The Write to us button on the Download page opens a mail with the tender name in the subject.
