Invoices
Payments are processed securely. To pay by ACH, card, or to update billing details, use the button on any open invoice — it opens a request to our billing desk and we’ll send a secure payment link.
Documents & deliverables
Deliverables are shared from STK’s secure drive. “Request” sends a note to your engagement lead, who will grant access to the file within one business day.
