Hello Adriano,

You need to customise Payplans Offline pay app to remove cheque option .
# Go to Root/plugins/payplans/offlinepay/offlinepay/app/offlinepay/transaction.xml , find below mentioned code

<field	name="from"

		type="parammanipulator" 

		default="Cash"

		class="form-control" 

		label="COM_PAYPLANS_APP_OFFLINE_TRANSACTION_FROM_LABEL" 

		description="COM_PAYPLANS_APP_OFFLINE_TRANSACTION_FROM_DESC">

		<option value="Cash" params="amount,currency">COM_PAYPLANS_Cash</option>

		<option value="Cheque" params="id,amount,currency">COM_PAYPLANS_Cheque</option>

		<option value="DD" params="id,amount,currency">COM_PAYPLANS_Demand_Draft</option>

</field>

If you don't want to show cash in list , just remove this line of code

<option value="Cheque" params="id,amount,currency">COM_PAYPLANS_Cheque</option>

To change the language strings of cash , find the language string on below mentioned file path.
root/language/en-GB/en-GB.com_payplans.ini, near line no. 114 find language strings.

COM_PAYPLANS_CASH="Cash"

COM_PAYPLANS_DEMAND_DRAFT="Demand Draft"

2 - In this screen it is possible to add some information like for example '' send the voucher via email ''?
You just want to show the details or want to send email also. Where exactly you want to show the details so i'll assist. you.

The customer has given up using cash payment and will only receive via Pagseguro. Anyway, thanks for the attention =)
