I have an app on the app store that has been out for a few months with iAd banners and I get a few dollars every month ( not very much ) and I heard that you need a minimum of revenue to actually get paid. if this is true, how much do I need? do they cumulative every month or do I need that minimum every month and therefore won't get any of the money I earned these past few months? thanks for your answers!
Your revenue is cumulative. Check this FAQ entry for the payment schedule and minimums.
When will I be paid? Payments are made within 45 days of the last day of the month in which app purchases were made. To receive payment, you must have provided all required banking and tax information and documentation, as well as meeting the minimum payment threshold.
If your bank and bank account currency is listed in this table, you must exceed a minimum payment threshold of $10 USD. All other bank countries and bank account currencies must exceed a minimum payment threshold of $150 USD.
