Anchor

Anchor is a billing automation platform that handles the cycle from engagement letter creation through invoicing and payment collection. It supports fixed-fee and usage-based billing models, automatically generates invoices on schedule, and collects payments via ACH or credit card.

Accounting firms use Anchor to automate their own billing process — creating engagement letters, setting up recurring invoices, and collecting payments without manual follow-up. Billing data syncs with accounting software for real-time revenue tracking. The platform aims to reduce the time spent on invoice generation, payment chasing, and billing reconciliation.

Anchor is best suited for firms that want to automate their billing workflow as a standalone tool. Firms already using practice management platforms with built-in billing (TaxDome, Karbon, Canopy) or proposal-to-payment tools (Practice Ignition, Cone) may find overlap with features they already have.
