If you need a pre-purchase invoice for your own purposes before making a purchase, you can select the Pre-Sale Invoice tab on your CASQA account page to create one or click here: www.casqa.org/how-do-i/how-do-i-create-invoice-advance-making-purchase

IMPORTANT: If not renewed by 11:59 PM Pacific time on the day before the expiration date, access to your CASQA member benefits will be denied. For those with group memberships access will also be denied for your sub-members. Member benefits include the Bi-Weekly Update, Water Quality NewsFlash, Member Library, Member Forum, and member discounts to products and events. If you did not renew your CASQA membership before the expiration, it can be re-purchased.
