Get paid on autopilot, from proposal to paid
About Anchor
Anchor is an autonomous billing and collections platform for accounting firms, bookkeepers, and professional services businesses. It turns signed proposals and agreements into automatic invoices and pre-approved ACH or card payments, then reconciles them with QuickBooks Online or Xero. Instead of a subscription, Anchor charges a flat $5 per payment received.
