The app stopped syncing after the last update and support took a week to reply. We lost orders during the outage and had to switch to a competitor.

About Pendulum Invoices
Pendulum is for Shopify shops where the order is just the start. Custom apparel, embroidery, signage, jewelry, catering, and B2B manufacturers run on quotes and draft orders, then wait days or weeks to get paid. Shopify sends one plain invoice email and stops. Pendulum picks up with branded PDFs that match your store in light and dark themes, a multi-step reminder cadence with your tone and copy, and W-9 and ACH links on every customer touch. Replies route to your inbox.
