To have your activations billed correctly on your invoice, you should always set up your Suggested Retail Price in the Create License page when setting up a SKU (for more details please see http://www.inishtech.com/Support/FAQs/FAQs/SLP-Service/SRP.aspx). Please make sure that all your SKUs already created also have their correct SRPs set up, as this is the only way that you can be sure that your activations will be charged correctly.
