These are customized sheets done with Google Sheets. They work with Excel as well, and maybe with OpenDocument. 

There are two sheets: Cuenta and Partidas. 

....
In Cuenta you can note all the expenses and income. You could: 
- Write the date manually. (Writing =TODAY( or =HOY( will put the current date automatically). 
- Give a name. I recommend you to write the same name that would appear in your bank account for each transaction. 
- Write a description. 
- You will be able to choose if it's an income or an expense. You will see a dropdown menu there with differente categories. 
Include your amount. The TOTAL INCOME column is a summation (which can be really useful)!
- Same for expenses!
- You can iclude as well how you paid or charge the amount. 
- The last column is the balance. 

....

Partidas is where the categories are. 
There you can complete the [Income type] cells. If you delete them it may appear as a white option in the drodown menu.


Be careful with deleting cells since you may delete also the formula!
