What is Anchor, and how does it work for accounting firms?
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.
How much does Anchor cost?
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.
What happens when the scope of work changes mid-engagement?
Anchor's one-click amendment feature lets you update billing terms, scope, or amounts in real time without restarting the agreement process. Changes can apply automatically or require manual approval, and invoices update themselves when an amendment is accepted — no manual corrections needed.
What payment methods do clients have access to?
Clients can pay via ACH bank transfer (free, with a standard 3-day transfer time) or by credit and debit card (2.9% + $0.30 processing fee). Your firm decides whether card processing fees are passed on to clients or absorbed in-house. All transactions are protected with bank-level security through Anchor's dedicated client portal.
Is Anchor suitable for firms with multiple team members?
Yes. Anchor includes team management features that let you add as many users as your firm needs. You can assign and customize access permissions per user — controlling who can create, edit, or view proposals, invoices, and client information — making it easy to delegate billing tasks without losing oversight.
Does Anchor support partial payments and deposits?
Yes. You can set up partial payments or deposits directly within a proposal. If you need to add a charge after an agreement is already in place, you can send a new invoice with a single click — no need to create a new proposal or amend the original agreement.
Does Anchor replace manual invoicing entirely?
Yes. Once a client signs their agreement and connects a payment method, Anchor automatically generates and sends invoices based on your billing schedule — whether recurring monthly, project-based, or one-time. There is no manual entry, no chasing clients, and no risk of a billable item slipping through the cracks.
How does Anchor ensure clients pay on time?
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.
How does Anchor improve cash flow predictability?
Because payments are collected automatically based on pre-approved terms, revenue arrives consistently and on schedule. Anchor's business dashboard provides real-time visibility into revenue forecasts, invoice pipelines, outstanding amounts, and upcoming collections — giving firm owners the data they need to plan confidently and eliminate cash flow surprises.
What integrations does Anchor support?
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.
How long does it take to set up Anchor?
Most firms are fully set up in an afternoon. Unlike other automation platforms that can take up to three months to implement, Anchor is designed for fast, straightforward onboarding. You can import your service templates, apply your firm's branding, and start sending proposals the same day.
Can I customize proposals and invoices with my firm's branding?
Yes. You can add your firm's logo and tailor the colors of proposal and invoice templates to match your brand. Anchor also includes a library of predefined service templates to get you started quickly, and you can import your own templates for complete customization.
