Yes, absolutely! When you sign up, we automatically add 5 credits to your account so that you can fully check out how things work. If that's not enough, email us at hello@lemonink.co and we'll work on a solution that'll help you complete your tests. Probably just add some more credits :)

Yes. At the top of the Pricing page, there's a number field hidden within the "Order x credits for $y each" text. Edit the number and buy any quantity of credits you'd like.

Hopefully you won't. First we'll notify you by email when your account balance drops below 10 credits. Second, we encourage you to set up auto-recharge to automatically buy more credits when you're running low. You can configure both the threshold for triggering the recharge and the amount you'd like to recharge by. To configure that, go to the Payments tab.

No. We only charge you a credit when you sell an ebook. So 1 ebook sale = 1 watermarking = 1 credit. And that's all. Everything else, like storage and subsequent downloads of watermarked files are included in the price.

There's no additional charge for selling the same ebook in multiple formats. You can upload files in all the supported formats (EPUB, MOBI and PDF) and we'll watermark them together for the same price.
