and, of course, scrub the bathroom.

How long is she staying?  If overnight, you should prepare a meal or get some take-out that she likes.

Wine is OK, but don't go overboard.

Sorry dude but this would be a huge red flag for me. If you can't have privacy I would get a hotel room.

So I am having a provider over to my house next week. I did incall with the few providers I've seen before. I've seen this provider twice before so she's comfortable enough to come to my place. I've never done outcall before though so I'm not sure what the proper etiquette is. Do I have drinks to offer her? Should I make sure my place is super clean? Is it ok if one of my roommates might be there? When I invite her in do I immediately take her upstairs? These might seem like stupid questions, but I just want to make the experience as comfortable for her as possible.

In general, I would recommend that you clean the place, and get rid of the roommate - she may not be comfortable with him/her being there, unless you have already told her that your roommate will be home (some ladies might not have a problem with it, others will).  In terms of how much to clean, that depends on the lady - when you have seen her, if her incall is relatively neat and clean, then you should try to make your place at least as clean.  If her incall is a total mess, then maybe she will not be as picky about yours  In term of drinks/conversation, I would keep things similar to when you see her at her place - if you normally sit and talk for a bit, plan for that at your place - if she jumps your bones as soon as you are through the door, you may be able to move things up to the bedroom sooner.

Having drinks would be nice, since you've been with her, you should know what she likes. Yes make sure the place is super clean. And there should be no one else in the  house. Make sure all the roommates are gone. You might spend a few minutes cathing up with her in the living room, then take her bcd.

NO ONE else should be there, when she arrives or while she's there.  If she is staying over night that is different.

Other than that, you invited her over.  Treat her the way you would any other guest.  Since you have seen her you should have some idea about her likes for munchies, music, etc.

Clean is always good.

Drop a few coins on a cleaning service.  For half of a donation you can have a spic and span place then maintain it once or twice a month with a per diem housekeeper. You never know when you would like to host again  Give the roomie some dinner and movie money and say "FO for the evening bud!"

When I have hosted in hotel rooms I have asked prior what the lady likes.  Champagne, red or white wine or tea.  I usually have a small plate of hors d'oeuvres.  Soft lighting and a special mix of music.  If the provider is comfortable with you enough to come to your place I'm sure by now you know a few things about each other.  The little things you do for her will go along way! I once adorned a hotel room with candle light and rose petals on the bed. I was her first client and wanted to make it EXTREMELY special for her. She's now retired   I can't help it, my handle was chosen for me by my ATF because of my behavior.
This may be a little over the top for some but, Hey it's my fantasy I'm paying for so why not make the most out of it!  I do this in my civie life and it works rather well there too!

I go all out when hosting a outcall.  I'll clean the bathroom, change the bedding, vacuum, dust, wash the dishes.....  I want the place perfect and clean and it gives me something to do before the big event.  I will set up candles in the bedroom, have a bottle of wine chilled, make sure there are extra towels in the bathroom for her for afterwords.  I like to talk a little when she arrives over a glass of wine and a smoke if she smokes.  One thing, don't open the bottle of wine until she arrives so that she knows it is safe and not laced with anything.  We will usually talk for 30-45 minutes maybe while I give her a footrub or until I can't take it anymore, then I'll light the candles and ask if she would like to join me in the bedroom.  This way she feels like it is a actual date and it feels so much more real.

Never disclose the HOBBY to ANYONE.  Not your best friend, your room-mates, your brother...  ever!  If you meet the girl of your dreams & decide to marry...  NEVER tell her about the Hobby.  Admit to having "girl-friends"...  no need to say how long they were your GFs for!

You really don't want to give someone this power over you.  You don't want your drunk buddy to stupidly out you as a "joke".  

Except for here on these boards...  and we don't know your real name...  you take this to the grave with you.

I'm outcall only, and have been to several different gentleman's homes.  I won't go if anyone else is home, even if it's someone I have been with before.  

And although I don't generally care about the condition of the place, I do use the bathroom and that DOES matter.  I had a client ask if I minded his messy apartment, and I said no, just make sure the sheets are clean.  And he did.  We sat on the bed and chatted before taking things further.  I appreciated the clean bed and cleaned up bathroom, both of which I knew and was aware that he did just for me.  

So if your not a generally neat and clean type guy, make sure you clean up the areas she will be accessing, especially the bathroom!!!

Have fun!

we've pretty much gone straight to bcd. Since I don't drink, we chit-chat a little as we're walking there. After that, it's all fun.

Oh, and as said, the sheets and bathroom are all I'm really concerned with as far as clean goes. I don't live in your home, so the clutter doesn't bother me.
