Readings and turnover

Enter the number on the meter face, not the units you think were used. Letnook works out the difference and shows the charge and the new total before you save.

    Open the space

    Tap a space showing Not billed yet, on the plan or under that filter in Collect.

  2. 2Read

    Tap the reading button

    Tap Record Electricity reading (or Water). The sheet shows the Previous reading.

  3. 3Type

    Type the meter's number

    Enter the number printed on the meter. The preview shows the Consumption, the charge and the bill's New total.

  4. 4Save

    Save

    If the preview looks right, tap Save. When every input is in, the space turns Due.

Save stays grey while the number is blank, negative or lower than the previous reading: a meter only counts up.

Declare turnover

For a space with a revenue share, tap Declare turnover and enter the tenant's turnover for the period. The preview shows the Revenue share, already limited by any cap, and the New total.

Check before you save

Once saved, the reading or turnover is used for this period's bill and there is no screen for changing it, so look at the preview first. If a meter was replaced, set its Carried-over reading in the space's editor to the new meter's starting number before you record the period's reading.
