Anchor
Autonomous billing platform for accounting firms.
About Anchor
Anchor handles the full billing cycle for accounting firms — from drafting and sending engagement letters to collecting recurring payments — without anyone manually chasing invoices or following up on unpaid balances. Once you set up a client engagement, the platform generates the letter, gets it signed, triggers the billing schedule, and processes payments automatically through Stripe. Partners stop touching collections entirely for most recurring client relationships. It fits firms billing on retainer or fixed-fee arrangements best: monthly bookkeeping packages, ongoing tax advisory, or annual compliance work. Sole practitioners and firms up to around 20 staff get the clearest benefit. If you run a project-heavy practice with highly variable billing each month, the autonomous model creates more exceptions to manage than it eliminates. The main gaps are integration depth and reporting. QuickBooks sync covers basic invoice matching, but Anchor is not a replacement for your practice management system — it does not track time, manage tasks, or produce the billing analytics that Karbon or Financial Cents offer. You are also committing to Stripe as your payment processor, which adds a transaction fee layer on top of Anchor's subscription cost. Smaller firms should model that combined cost against what they currently pay before switching.
Best for
Accounting firms wanting to eliminate manual invoicing with autonomous billing and payment collection
Key Features
- Autonomous billing from proposal to payment
- Automated engagement letter generation
- Recurring billing automation
- Automated payment collection
- Client portal for payment processing
Pros & Cons
Pros
- Generates and sends engagement letters automatically, then triggers billing once the client signs — no manual handoff between proposal and invoice.
- Recurring billing runs without partner involvement: schedules, charges, and sends receipts on autopilot for fixed-fee and retainer clients.
- Automated payment chasing handles overdue balances without you sending awkward follow-up emails.
- Built exclusively for accounting firms, so the engagement letter templates and billing logic reflect actual practice workflows rather than generic service-business defaults.
- Client portal lets clients view invoices, update payment methods, and pay without calling the office.
- QuickBooks integration pushes paid invoice data into QBO, reducing double-entry for firms already on that stack.
Cons
- No free tier and no stated trial period — you commit financially before you can fully evaluate fit with your existing client roster.
- Stripe is the only payment processor; you cannot route payments through Square, PayPal, or direct ACH outside the Stripe infrastructure, and Stripe's per-transaction fees stack on top of Anchor's subscription.
- Reporting is thin. You cannot pull billing performance analytics, realization rates, or aging summaries comparable to what dedicated practice management tools provide.
- No time tracking or WIP management, so variable-fee engagements require manual invoice creation that undercuts the autonomous billing pitch.
- Smaller user community than category incumbents like TaxDome or Ignition means fewer third-party tutorials, integrations, and community workarounds when you hit edge cases.
- Switching costs are real: engagement letters and client payment methods live inside Anchor, making it disruptive to migrate away once your client base is enrolled.
Ledger Brief Take
Built specifically for accounting firms rather than general service businesses, Anchor automates the entire billing lifecycle from engagement letters through payment collection — a workflow most practice management systems handle piecemeal. The autonomous billing claims are legitimate here, with smart recurring setups and payment chasing that actually reduce partner involvement in collections.
Frequently Asked Questions
Common questions accountants ask about Anchor.
How much does Anchor cost?
Anchor does not publish a detailed pricing page with specific tier costs. Pricing is subscription-based and paid, with no free plan available. Contact Anchor directly for current rates. Factor in Stripe transaction fees on top of the subscription when calculating total cost per collected invoice.
How does Anchor integrate with QuickBooks?
Anchor connects to QuickBooks Online and syncs paid invoice data across, reducing manual entry. It does not replace QBO for expense tracking, financial reporting, or payroll. The integration covers the billing and collections side only — QuickBooks remains your accounting system of record.
How does Anchor compare to Ignition?
Ignition is the closer comparison than TaxDome. Both handle proposals, engagement letters, and recurring billing for accounting firms. Ignition offers broader payment processor options and stronger reporting. Anchor's autonomous payment chasing is more hands-off by design. Ignition has a larger user base and more established integration ecosystem.
Is Anchor secure enough for client financial data?
Payment processing runs through Stripe, which is PCI-DSS Level 1 certified. Anchor itself operates on standard cloud infrastructure with encryption in transit and at rest. It does not store raw card numbers. Review Anchor's current security documentation before onboarding clients with sensitive advisory relationships.
What size accounting firm is Anchor built for?
Anchor works best for sole practitioners and small firms up to roughly 20 staff who bill on retainer or fixed-fee schedules. Larger firms with complex billing arrangements, multiple service lines, or heavy project-based work will hit the platform's limitations quickly and likely need a full practice management tool instead.
Can Anchor handle variable or hourly billing?
Not well. Anchor is built around fixed and recurring billing. It has no time tracking, so hourly or variable engagements require manual invoice creation outside the automated workflow. If a meaningful portion of your billing is time-based, Anchor covers only part of your invoicing needs.
