Anchor is an autonomous billing and collections platform built specifically for accounting, bookkeeping, tax, and professional service firms. It connects every step of the client payment lifecycle — proposals, agreements, invoicing, and payment collection — into one continuous automated workflow. When a client signs a proposal on Anchor, they simultaneously connect a payment method. From that point, invoices are generated and sent automatically according to your billing terms, and payments are collected without any manual follow-up from your team.

Anchor is free to start. No credit card or subscription fee required. Anchor charges a flat $5 fee only when money moves, so you pay nothing until you get paid. ACH payments are free for your clients; credit card payments carry a 2.9% + $0.30 processing fee that can be passed on to clients or absorbed by your firm.

Anchor complements QuickBooks rather than replacing it. QuickBooks records your revenue; Anchor secures and collects it, then syncs every payment back in real time so your books stay current without manual reconciliation.

Anchor eliminates late payments by requiring clients to connect a pre-approved payment method before signing any agreement. When a payment is due, it is collected automatically based on the agreed terms, no action required from the client and no follow-up required from your team. Because payment collection is built into the agreement itself, late and missed payments are structurally removed from the process.Yes. Set up milestone payments directly in the agreement and Anchor invoices automatically when each one is due, so project billing stays on schedule without manual tracking.

You can simply add the charge directly to the live agreement. The invoice updates automatically and the additional amount is collected on the next billing cycle, with no new contract required.

Every billable item lives in the signed agreement. Invoices are generated automatically from that agreement rather than depending on someone remembering to bill. When scope changes, simply update the agreement and the next invoice will reflect it automatically.

Anchor is completely free to use and only charges a flat rate of $5 for every successful transaction processed through the system. There are no monthly subscription fees, setup costs, or hidden platform charges.

CH payments are completely free, and you have full control to either absorb the processing fees for credit cards or pass them directly to your client. This allows you to dictate your exact billing mechanics during the initial agreement setup.

Anchor notifies you the moment a dispute is raised. If the client pauses a payment inside Anchor, it simply goes on hold until they click "Resolve," and no fee applies. If they dispute through their bank or card company instead, Anchor flags it and works with you and the client to resolve it within the required timeframe.

Anchor integrates with QuickBooks Online, Xero, Karbon, Keeper, Client Hub, Financial Cents, and monday.com. Payment and invoicing data syncs automatically, keeping your books up to date and reconciliation clean without manual exports or re-entry.
