Hey STMers,
We have cash in 5 or so traffic sources and 10 or so affiliate networks/direct advertisers that we don't use all the time. All in all id say we have up to 3-5k just lying around and we can't get this money back lol. Is this normal and what can be done about this?
Tell me about it... I had $40k at content.ad and left it for a while. Now they say it was an accounting error and I'm owed zero.
It's pretty normal I'd say. I pretty much have 10k+ sitting in networks and traffic sources combined at all times.
Anyone doing some volume is facing this, minimum payout thresholds combined with minimum loads at traffic networks ... there is no way around it. We always have $xx.xxx in the "air" because of this 
Yep, cashflow is king
Yep, pretty normal, and the more volume you do the more cash you have to float.

I think the affiliate network problem is a bigger issue cuz you can just spend the traffic source funds
Haha, pretty normal
Several thoughts that may help (not specifically aimed at the OP but mainly for any newbies reading this thread):
1)For those that don't have much cash to float, it would be better to focus on a few aff networks. Either choose a few that have massive amounts of offers, or if you already know which vertical to focus on, choose a few networks that specialize in your vertical. Just test more geos to make up for being restricted to a few aff networks.
2)Same applies to traffic sources - focus on the few big ones you've had the most success with. Again, just test more geos to make up for being restricted to a few sources.
3)Make smaller deposits to each traffic source. Yes It gets really annoying to have to check often to make sure the balance isn't exhausted on each source, but it only takes like 5 minutes a day to do - maybe ask an assistant to do it.
4)If you're starting to run out of cash, see which aff network has a balance closest to payment threshold, and run more traffic to their offers to get that payout. If you don't have any offers running at the moment, see which vertical+geo the network has lots of offers for (can ask AM about this) and start testing (of course include offers from the other networks too for this vertical+geo, while you're at it).
5)If starting to run out of cash, put the lower-ROI camps on pause to reserve more cash for the higher-ROI camps.
Any other tips? Great discussion!

Say you leave $400 in clickdealer for a year. Is that money gone or is it there forever?
I've had network fail, owners vanish.
Then they started a new network a year later, and paid me what they owed from old network to get me to run with them again 
Leadimpact took $ 1k after "floating" it for 1 year. I've tried contacting them multiple times and all I got was some stupid half-human/half-robot replies. Luckily I've had that payment made with my AMEX and since I'm spending 6-figures with them every monthly they were happy to just credit that 1k
Anyone having any money (and not using it) with LeadImpact better do something about it.
