So, I'm new to QB and book-keeping in general! But I'm slowly learning.

I recently learned how to enter credit card charges, to record expenses for job materials, tools, etc. But now I'm learning that I need to reconcile these, to get a 0 balance to show? And that I have to do it via entering bank information + credit card information then make the payments on QB?

My question is... is the making payments on QB actually going to take out of my bank? Or is it just a recording of a payment that's been made? I.E. If I've put a credit card charge for 100$ toward Home Depot as the vendor, then if I input it as a payment as well, to balance it to 0, will it actually take from my bank account and pay the select CC [the one related to the charge?]? 

Likewise, if I record  my bills and "make a payment" on QB for them, will it take from my bank or just record that the payment was made? 

I'd rather be safe than sorry, thus why I'm asking, haha. Thanks in advance!
