As soon as we get your purchase order, an invoice will be generated and sent within two weeks. If you need it expedited, please contact Jen@teachermade.com. Please note: many school districts email servers don’t allow attachments to emails from outside the organization. If this is the case in your district, please whitelist the TeacherMade.com domain on your email server or we will be unable to send you an invoice, possibly resulting in account shut-offs. Not trying to be mean, just saying it’s a real problem.
