What is ChaseKit?
ChaseKit is a payment follow-up toolkit by StackLoom for freelancers and small agencies. It combines an invoice and payment tracker, follow-up scripts for email and WhatsApp, client payment templates and a quick-start guide.
Late invoices are easier to handle with a consistent process than with messages written from scratch each time. ChaseKit gives you that process as a set of ready-to-use files.
01
See what is outstanding
The Invoice & Payment Tracker keeps invoices, due dates and payment statuses in one place.
02
Know what to say
Payment Follow-Up Scripts give you professional wording for email and WhatsApp reminders.
03
Set expectations early
Client Payment Templates cover payment terms, deposits and overdue invoices.
