Even if you don't chase checks, I'm sure you chase clients around their schedules to get paid. That's the pain that Anchor fixes. I'm so excited!

When I started my business, I bought a brand new car to pick up my clients' checks all over town. It had 160.000 miles on it two years later. Even if you don't chase checks, I'm sure you chase clients around their schedules to get paid. That's the pain that Anchor fixes. I'm so excited!

"Perfect for any service based business"

Anchor has allowed me to provide clients the ability to choose the package that works for them while automatically collecting payment monthly.  It has removed me for collecting payment which has been a huge time saver as a solo firm runner."

FAQ

Does Anchor integrate natively with standard accounting software?

Yes, Anchor integrates natively with major ledgers like QuickBooks Online and Xero, automatically syncing invoices, cleared payments, and deposit records straight to your ledger for zero-touch reconciliation. You can explore the complete list of supported accounting and workflow tools on our Integrations page.

How does Anchor handle hybrid consulting pricing models like mixed retainers and variable hourly rates?

Anchor features a flexible billing engine that combines fixed project milestones, recurring strategy retainers, and variable hourly or ad-hoc line items into a single unified client agreement and invoice.

Can I automate annual price increases on long-term strategy retainers?

Yes. You can embed scheduled percentage rate escalations directly into your master agreement templates, allowing the platform to automatically adjust retainer billing over time without manual contract renegotiations. Read how PBS Consulting automated their annual price updates.

How are out-of-scope consulting tasks or additional advisory hours added to active agreements?

You can attach variable out-of-scope line items or expenses directly to active client agreements via instant amendments without drafting new engagement letters.

Can Anchor manage financial operations and revenue tracking across multiple separate consulting entities or subsidiaries?

Yes. Anchor’s multi-entity architecture centralizes financial operations, revenue tracking, and client portfolios across distinct consulting entities from a single unified login and dashboard.

Can team permissions be restricted to control access?

Yes. Granular access controls allow you to assign custom team roles that restrict who views or edits agreements, keeping firm-wide revenue data strictly private.

What data security and encryption standards protect sensitive client financial information on the platform?

Anchor uses up to 256-bit TLS encryption for all data transmissions, enforces strict physical access protocols with 24/7 server monitoring, and never stores raw credit card or bank account credentials.

What payment methods are supported on the platform, and what are the exact processing fees?

Anchor supports ACH bank transfers with $0 processing fees, while credit card payments incur a standard 2.9% + $0.30 fee that can be transparently routed to the client. Review Anchor's transparent billing models and pricing.

If I have a large portfolio of existing consulting clients, can I migrate them all to Anchor at once, and how long does it take?

Yes. You can instantly import existing clients in bulk using previous agreements via Anchor's import tool, or utilize white-glove onboarding to migrate batches of 30+ clients seamlessly without friction

Do you operate internationally and support cross-border client payments?

Anchor currently exclusively supports consulting firms registered and operating within the United States, while allowing you to bill global clients. International clients can pay using a credit card or an American bank account.

What happens if a client's pre-approved payment method fails?

If a client stops a payment within Anchor, it is placed on hold free of charge until they click "Resolve" to let it proceed. If a payment fails due to an external dispute or ACH return, it is marked as failed—incurring a $20 chargeback fee—and you can manually retry processing it in your dashboard after reviewing the issue with your client.

‍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.

‍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.
With Anchor, your invoicing and payments data automatically syncs with QuickBooks Online, ensuring a successful reconciliation and keeping your books up-to-date.
