-Generate recurring vendor bills
-===============================
-
-You may receive vendor bills for a fixed amount on a regular basis: for
-instance, for water, gas, electricity or phone bills. For such cases,
-the recurring vendor bills feature will save you a lot of time. Indeed,
-all you need to do is to create a bill once, set a frequency of
-recurrence and the rest will follow. Your next bills will automatically
-appear in your feed.
-
-How to activate the recurring vendor bills feature
---------------------------------------------------
-
-For this feature to work, go in
-:menuselection:`Invoicing/Accounting --> Configuration --> Settings` and
-tick the box in front of Recurring Vendor Bills to activate
-the feature. Finally, do not forget to save your settings from the
-top-left corner of your screen.

-Generate recurring vendor bills
--------------------------------
-
-You can either select an existing bill or create a new one for this
-purpose. Once you are editing the vendor bill, access the "other info"
-tab. On the bottom right corner, you can see that the option "recurring
-bills" is available. Tick the box and set the frequency you would like
-to have. It can be every (other) day, week, month, or year. Finally, do
-not forget to save the bill.

-
-.. tip::
-    The recurring bills will only be generated if the bill is
-    validated. If the bill is cancelled, recurring bills won’t be generated
-    anymore.
-
-The recurrency depends on the bill date and on the recurrency defined. In
-the example below, the bill date is on the 13th of January and the recurrency
-set is "every 1 month(s)". In this case, the next bill will be generated on
-the 13th of February.

-draft, you will just have to verify and validate them.
