I've been reading through the EotE core book, and I can't find any info on how to pay the players during the campaign. I found the section making recommendations on non-monetary rewards for players, like ship repairs or obligation reduction, but nothing on directly giving the players money. What kind of jobs should I offer players and how much should they pay? How regularly should the players receive payouts? Once a session? One in five? I can't find any details that fully cover this.
How to give Players credits
Well, there's the Quartermaster tree that has "Get some cash every game from your investments" talent, but beyond that I don't think there's a mechanic for the GM just handing out money.
As far as jobs - there's always my Random Cargo Generator and my Random Job Generator. Mind you, the actual payouts of these are up to the GM's discretion - but it's a good start.
I just kind of wing it. Awhile ago my players made a huge score of around 75,000 credits. However, out of that amount they used over 50,000 credits to pay for repairs on their ship since it had been so heavily damaged (it was nearly destroyed). Then they paid off the remainder of their debt to a Hutt (I allowed them to have a YT-2400 as their starter ship provided that they owed the Hutt about 40,000 credits). Then by the time they bought any supplies I think they ended up with around. 8,000-9,000 credits left.
But here recently they haven't had a chance to make that kind of money again. So really just go with your gut on what seems appropriate to the story.
I've been winging it to and it's bit me on occasion. I've mitigated large scores much like Daniel Anteron has done: owning a starship is an expensive venture.
It is really tough to pay them the "right" amount. I am really wanting to go for that dirtier edge living job to job barely scrapping by kind of feeling. And it can be really tough without your group thinking you are just being a "summer''s eve". Just living is expensive. Yes, they eat the rations on the ship, but I think of those as being just that, rations. It will keep you from starving, but that's about it. So once planet side, they should restock on fresh fruits, vegetables and dairy. Also, just going to the convince store to pick up that energy drink and candy bar, not to mention those low fat lattes at the stim caffe. Also, after a couple of adventures of running, dodging, rolling and getting shot, the clothes will be falling apart. I won't even mention the "nocturnal" adventuring.
I figure most ships the PCs have are about the size of C-130 airplane and maybe up to the size of a C-17 cargo hauler. Just for one those to fly is horribly expensive, and then the cost for the maintenance crews and hours spent on them to keep them flying. There is always minor to major repairs that have to be done to them to keep them in optimal flying status for missions, and that is when they are not in a combat zone getting shot.
I am trying for a mix of a little realism with out horrendous book keeping with my group. I don't want an itemized list of your foot locker with the number os socks, underwear and tank tops. Oh you rolled a threat in combat, your sock blew open at the toe, you need to by a new pair! Two threat, the back of your pants split open, should have went for the low fat latte, not the triple mocha!
So I feel it is trying to get that right mix of a little realism with heroes. Do you guys remember that awesome episode of A-team at the Old Navy and Gap? Yeah, me neither.
So talk with your group, and see what it is they want from the game. Like XP, the quicker you get it, the quicker the enemies get that much tougher too. See what it is they want From your campaign, and see what kind of book keeping they want to do, and that will go a long way in telling you how much they should be making per job.
As far as payouts go, for me it is usually one time per adventure. Well, ok maybe two. Once at the beginning and once at the end. When they are getting their job setup, they may be able to get a cut up front to help cover some expenses, and then the rest once they complete the job. But there are no mechanics in the game or hard and fast rules when it comes to paying your group.
Hope this helps a little.
If you feel a need to account for various daily expenses, just assume d% credits spent per character per day. This covers general upkeep too.
