About the Pendulum Invoices

Pendulum handles invoicing and payment reminders for Shopify stores that work with draft orders, B2B sales, and custom work. Perfect for custom apparel, embroidery, signage, jewelry, catering, and manufacturers who quote first and get paid later. While Shopify sends one plain invoice email and stops, Pendulum continues with branded invoice PDFs that match your store in light and dark themes. Set up multi-step payment reminder cadences with Friendly, Firm, and Urgent tones using your own copy. Every invoice and reminder includes W-9 and ACH instruction links. Replace Shopify's standard order confirmation and draft invoice emails with branded versions. Customer replies go straight to your inbox, not a no-reply address.
