8 Best Anchor Billing Alternatives for Accountants (2026)

Anchor (sayanchor.com) has carved out a niche with a simple promise: no subscription, no setup fee, just $5 deducted from each payment you collect. A signed proposal turns into an agreement, and Anchor invoices and charges the client automatically from then on. Reviewers love how hands-off it is. But Anchor is a billing tool, not a practice management platform, and the per-payment fee grows with every client you add. For most firms, Tidyflow is the strongest replacement, putting proposals, automatic billing, workflow, and a client portal on one flat $39/user/month ($29 billed annually) plan. Here are the 8 best Anchor alternatives for accounting firms in 2026.

At a Glance: Anchor Competitors Compared

Why Look for Alternatives to Anchor?

Anchor does one job very well: it gets firms paid on time without anyone chasing invoices. Most firms that move on do so for one of three reasons:

• The fee grows with your client list. $5 per payment is cheap at 10 clients and noticeable at 100. A firm billing 50 clients monthly pays about $3,000 a year in Anchor fees, and that’s before card processing. Anchor’s model rewards firms with few, large payments and penalises firms with many small monthly ones.
• Billing lives apart from the work. Anchor has no workflow, task management, client requests, or time tracking of its own. Most firms run it alongside a practice management tool, which means two subscriptions, two client records, and a sync to keep healthy.
• Less control over documents. Reviewers mention that invoices can’t carry attachments, layout and terms are hard to customise, and no engagement letter templates come preloaded.

Anchor is also built for US firms billing in US dollars, so firms outside the US usually look elsewhere from the start.

1. Tidyflow

Tidyflow gives you Anchor’s “proposal to paid” flow and the rest of the firm’s operations in the same place. Proposals and engagement letters can collect payment details at signing, and an accepted proposal bills on acceptance, on job completion, or on a recurring schedule, then auto-charges the card or bank account the client saved. Clients pay by card or ACH bank transfer through Stripe at standard processing rates, with no Tidyflow fee per payment, and US firms can pass card fees on to the client.

The difference from Anchor is everything around the invoice. The same client record holds the workflow for their monthly books or tax return, the client portal where they upload documents and answer questions, unlimited e-signatures, and time tracking. Billing works from time as well as fixed fees: unbilled work is grouped by client, you can bill a client’s whole WIP in one click, and every draft opens on a review screen with live write-ups and write-downs before anything is sent. Invoice reminders go out automatically, and invoices sync with Xero or QuickBooks Online.

• Best For: Firms that want billing and the work behind it on one subscription, without paying more as they add clients.
• Key Features: Proposals with A/B/C packages and engagement letters, payment details captured at signing, automatic recurring invoices and auto-charge, card and ACH payments via Stripe, billing from WIP with a review screen, invoice reminders, workflow management, client portal and requests, e-signatures, time tracking, Xero and QuickBooks sync, Tidyflow Agent.
• Pricing: Core $39/user/month ($29 billed annually), Pro $69/user/month ($55 billed annually). Free 14-day trial, no credit card, no user minimum.
• Why It Beats Anchor: Flat per-user pricing that doesn’t rise with every payment you collect, plus workflow, client requests, and time tracking that Anchor leaves to a second tool.
• Where Anchor Is Better: Anchor has no monthly fee, so a solo practitioner with a handful of clients may pay less, and its time-tracker integrations can auto-bill hours from tools like QuickBooks Time or Harvest.

2. Ignition

Ignition (formerly Practice Ignition) is the tool Anchor is most often compared against, and the closest like-for-like swap. It covers proposals, engagement letters, automatic billing, and payment collection, with a larger integration marketplace and features Anchor lacks, such as bulk proposal renewals and price increases. Pricing runs from $39/month to $399/month (billed annually) on tiers set by how many active clients you bill, with overage charges once you pass a tier’s limit and per-transaction payment fees on top. (See our full Ignition alternatives breakdown.)

• Best For: Firms that like Anchor’s automation but want a more established tool with deeper proposal features.
• Key Features: Proposals, engagement letters, automatic billing and collection, bulk renewals, client pipeline, large integration marketplace.
• Downside: A fixed monthly fee that climbs with your active client count, plus payment fees; still a billing tool with no workflow of its own.

3. Cone

Cone is the lowest-cost swap for firms that want to keep proposals and billing in a dedicated tool. It covers proposals, engagement letters, automatic invoicing, and payment collection with unlimited clients and proposals, and charges per user instead of per payment: Propose plans start at $9/user/month billed annually, and its lighter Practice plans (adding workflow and a client portal) start at $5/user/month annually or $8 monthly. Payments run through Stripe or GoCardless at the gateway’s own rates, and Cone publishes pricing for UK and Australian firms as well as US ones.

• Best For: Cost-conscious firms that want a proposals-and-billing tool with predictable per-user pricing.
• Key Features: Proposals, engagement letters, automatic invoicing, Stripe and GoCardless payments, unlimited clients, Xero and QuickBooks integration.
• Downside: Newer platform; its practice management features are lighter than purpose-built tools.

4. GoProposal (by Sage)

GoProposal, owned by Sage, is built around a pricing engine: you set up your services and pricing rules once, and every proposal is priced consistently from that menu. It produces engagement letters, syncs with Xero and QuickBooks, and is most popular with UK and Australian practices. Plans are tiered by proposal volume, from £77.70/month in the UK and $75/month in the US. (See our GoProposal alternatives breakdown.)

• Best For: UK and AU firms that want every quote priced from the same structured menu.
• Key Features: Pricing engine, proposals, engagement letters, e-signatures, Xero and QuickBooks sync.
• Downside: Billing and collection rely on integrations rather than happening inside the tool, and it has no workflow or client portal.

5. Financial Cents

Financial Cents is a workflow-first practice management tool that includes proposals, engagement letters, invoicing, and payments on every plan. It’s a good fit for small bookkeeping firms that want billing next to their recurring client work. Pricing starts at $19/month for a solo plan, then $49/user/month billed annually ($69 monthly) for teams. (See our Financial Cents alternatives breakdown, or the head-to-head Tidyflow vs Financial Cents comparison.)

• Best For: Small bookkeeping firms that want workflow and billing together.
• Key Features: Workflow, recurring tasks, proposals, invoicing, payments, client tasks.
• Downside: Monthly billing needs a five-user minimum; billing automation is less hands-off than Anchor’s.

6. Karbon

Karbon is a practice management platform built around email and team collaboration, and Billing & Payments is included on every plan. It suits mid-size firms that want proposals, invoicing, and collection in the same vendor as their workflow. Pricing starts at $59/user/month billed annually ($79 monthly). Karbon also integrates with Anchor, so some firms run both. (See our Karbon alternatives breakdown, or the head-to-head Tidyflow vs Karbon comparison.)

• Best For: Mid-size firms (5+ users) already running email-driven workflow.
• Key Features: Email triage, workflow, proposals and engagements, billing and payments, client portal.
• Downside: Higher per-user cost, and a heavier setup than a small firm usually needs.

7. Canopy

Canopy is a practice management platform with proposals, billing, document management, and a client portal, popular with tax and tax-resolution firms. Plans start at $74/user/month billed annually, and payments carry Canopy’s own processing rates. (See our Canopy alternatives breakdown, or the head-to-head Tidyflow vs Canopy comparison.)

• Best For: Tax firms that want proposals connected to a broader platform.
• Key Features: Proposals and engagements, billing, workflow, document management, client portal.
• Downside: Higher starting price, with costs climbing as you add tiers and modules.

8. TaxDome

TaxDome is an all-in-one platform for tax and accounting firms, with proposals, invoicing, payments, e-signatures, and a client portal in one subscription. It bills $800 to $1,200 per user per year, paid upfront annually. (See our TaxDome alternatives breakdown, or the head-to-head Tidyflow vs TaxDome comparison.)

• Best For: Tax-focused firms that want a portal-led platform and can commit annually.
• Key Features: Proposals, invoicing, payments, e-signatures, client portal, automation.
• Downside: Annual upfront commitment, and the breadth takes real time to set up.

What Anchor Really Costs as You Grow

Anchor’s pricing is easy to understand, which makes it easy to model. The table below counts only Anchor’s $5 fee, assuming each client pays once a month by ACH; card payments add 2.9% + $0.30 on top unless the client covers it.

For comparison, a 5-person firm on Tidyflow Core pays $1,740 a year billed annually, whether it bills 20 clients or 200, and that covers workflow, client requests, and the portal as well as billing. Stripe’s standard processing fees apply on top, as they do with any Stripe-based tool. If you bill a handful of large engagements a year, Anchor’s model will likely cost less. If you bill dozens of clients every month, a flat subscription usually wins.

What to Consider When Choosing an Anchor Alternative

• Stick with Anchor if you’re a US firm with a modest client count, you already have a practice management tool you’re happy with (Anchor integrates with Karbon, Financial Cents, TaxDome, and others), and you only want billing automated.
• Consider Tidyflow if you’re paying for Anchor and a separate practice management tool, or if you’re still running work on email and spreadsheets and want billing, workflow, and client requests in one system your team will actually use.
• Consider Ignition or Cone if you want to keep billing in its own dedicated tool and would rather pay a predictable monthly fee than a fee per payment.
• Consider GoProposal if you’re in the UK or Australia and want every proposal priced from the same menu.
• Payments: Anchor, Tidyflow, and Cone all collect through Stripe, so the client’s payment experience is similar. The difference is what you pay on top: a fee per payment (Anchor), a fee per active client (Ignition), or a flat fee per user (Tidyflow, Cone, Karbon).
• Switching: saved payment methods can’t move between platforms, so clients will need to accept a new agreement and enter their details again. Move clients across at their next renewal or engagement letter cycle rather than in one go.

Ready to Move Beyond Anchor?

Anchor makes getting paid effortless, and for some firms that’s all they need. But if you’re paying more each month as your client list grows, or keeping billing in a separate tool from the work itself, there are better-fitting options. Tidyflow stands out for firms that want proposals, automatic billing, and the rest of the practice on one flat per-user plan.
