Why Connect PayPal to Sage?

New team members take longer to onboard because they must learn manual workarounds to keep PayPal and Sage aligned

Sage adds complexity: migration between Sage products (e.g., Sage 50 to Sage Intacct) is not seamless and often requires professional assistance

Customers in PayPal and contacts in Sage drift out of sync, leading to outdated details on invoices, emails, and reports

Invoice and payment data is re-entered between PayPal and Sage manually, doubling the work and risking GST errors at month-end
