6 Best CAS Pricing and Packaging Tools for 2026

Client Advisory Services (CAS) has moved from a niche offering to the primary growth engine for mid-size accounting firms. But unlike compliance work, advisory services don't fit naturally into hourly billing. Packaging CAS into clear, tiered service bundles — and pricing them in a way that clients understand and buy — requires specialized tooling that most practice management suites don't provide natively.

The result: many firms that have made the CAS transition are still quoting advisory packages in Word documents or spreadsheet proposals, leaving pricing consistency, renewal automation, and engagement letter execution as manual, fragmented steps.

62% of accounting firms have adopted cloud-based workflow tools according to the AICPA 2025 PCPS CPA Firm Top Issues Survey. But dedicated CAS pricing and packaging tools remain underutilized — most firms haven't moved beyond spreadsheet proposals for their advisory services.

This guide reviews the 6 best tools for CAS pricing and packaging in 2026, with pricing benchmarks, feature comparisons, and a framework for selecting the right fit for your firm's size and service mix.

TL;DR: CAS pricing tools fall into three categories: proposal and packaging platforms (Ignition, Anchor), all-in-one practice platforms with pricing modules (Practice Ignition's evolved form), and value pricing frameworks supported by advisory tools. The best choice depends on your firm's advisory revenue target, client count, and whether you need native engagement letter execution.

Who This Is For

This guide is written for CPA firms and accounting practices that:

• Have launched or are planning to launch CAS or advisory service packages

• Bill at least some clients on a subscription or retainer basis

• Have 2 or more staff involved in client pricing and proposal creation

• Generate $500K or more in annual firm revenue

Red flags: Skip this if your firm is 100% compliance-focused with no advisory services planned. Also skip if you have fewer than 3 clients on retainer — a spreadsheet and DocuSign is genuinely more efficient at that scale. And skip if your team lacks the operational bandwidth to configure and maintain a pricing tool through the first 6 months of adoption.

What CAS Pricing Tools Actually Do

A CAS pricing and packaging tool does three things that general proposal software and practice management platforms don't handle well:

1. Service packaging: Lets you define tiered service bundles (e.g., Foundation / Growth / Advisory tiers) with itemized deliverables, included hours, and response-time SLAs — and present them to clients in a structured, comparable format.

2. Scoping and pricing logic: Applies firm-defined pricing rules to client attributes (entity count, transaction volume, payroll headcount) to generate a consistent quote rather than requiring each partner to build a proposal from scratch.

3. Engagement letter execution: Converts an accepted proposal directly into a signed engagement letter with billing authorization, without manual transcription.

Firms that price advisory services without dedicated tooling typically see 20–30% pricing inconsistency across partners — meaning similar-complexity clients pay materially different amounts depending on which partner quoted them.

The 6 Best CAS Pricing and Packaging Tools for 2026

1. Ignition

Ignition (formerly Practice Ignition) is the most widely adopted CAS proposal and engagement platform among accounting firms. It combines service library management, tiered proposal creation, engagement letter execution, and payment collection in a single platform.

Strengths: The service library lets you define standardized packages with fixed scope parameters. Proposals display in a client-facing format that looks like a pricing page — clients choose their tier, sign the engagement letter, and authorize payment in a single flow. Ignition also handles recurring billing, automatic renewal reminders, and price-increase notifications.

Limitations: Ignition does not do complex scoping logic natively (e.g., "charge $X per entity above 3"). The pricing rules are relatively flat — you set a price and it quotes that price. If your CAS offering requires multi-variable scoping, you'll configure that outside Ignition and enter the final number manually.

Pricing: Starts at approximately $79/month for small firms; mid-tier plans with higher proposal volume run $149–$299/month.

2. Anchor

Anchor is a newer entrant that bundles proposal creation, engagement letter execution, and automated ACH billing into a single platform with a cleaner setup workflow than Ignition. It is free for proposal creation and charges a percentage fee on collected payments.

Strengths: Zero monthly subscription cost for the base plan makes it accessible for smaller firms. The payment collection is clean, with automated retries for failed ACH payments. Clients can sign and pay from a mobile device in under 3 minutes.

Limitations: Anchor's service library and tiered packaging features are less mature than Ignition's. It works well for firms with 2–4 defined service tiers; firms with complex, multi-variable service menus will find it limiting.

Pricing: Free base plan (percentage fee on payments); Pro plans from $99/month.

3. Practice Ignition (Legacy Users)

Some firms still run the original Practice Ignition interface, which preceded Ignition's rebrand and UX overhaul. Legacy users retain access but are being migrated to the new Ignition experience. If you're evaluating new tools, the current Ignition platform is the relevant comparison — legacy PI is not a new-choice option.

4. Karbon (Proposals Module)

Karbon is a practice management platform with a proposals feature added to its workflow suite. For firms already using Karbon as their primary practice management tool, the proposals module provides integrated proposal creation with direct connection to job and task creation upon acceptance.

Strengths: Native integration with Karbon's workflow means an accepted proposal automatically creates the associated job in the platform, triggers onboarding tasks, and populates the client record. No manual transcription required.

Limitations: Karbon's proposal module is less polished than Ignition's client-facing experience. The pricing editor is functional but not designed for complex tier configuration.

Pricing: Karbon's full platform starts at $59/user/month; proposals are included in the Team and above tiers.

5. GoProposal

GoProposal (now a Sage company) is built specifically for the accounting industry and focuses on consistent, profitability-aware pricing. It includes a pricing calculator that factors in your target realization rate, service time estimates, and client attributes to output a recommended price — not just a blank quote.

Strengths: The pricing intelligence layer is the most developed of any tool in this list. Partners who use GoProposal report more consistent pricing across the firm and higher realization rates on fixed-fee engagements.

Limitations: GoProposal's engagement letter execution and payment collection are less integrated than Ignition. Many firms use GoProposal for pricing and Ignition for proposal delivery — a two-tool workflow.

Pricing: Starts at approximately $129/month.

6. Scopely (Scoping-First Tools)

Scopely and similar scoping-first tools take a different approach: rather than starting with service packaging, they start with a structured client questionnaire that determines scope, and then apply your pricing rules to output a quote. This works well for firms whose CAS scope varies significantly by client complexity.

Strengths: The scoping questionnaire discipline forces consistency in how scope is assessed before price is set — reducing the "ballpark guess" problem in complex engagements.

Limitations: Less polished proposal output than Ignition or Anchor. Better as a backend scoping engine paired with a front-end proposal tool.

Pricing: Ranges from $89–$199/month depending on user count.

Head-to-Head Comparison: Pricing and Features

Benchmarking CAS Package Pricing in 2026

One of the most common questions from firms launching CAS is: "What should we charge?" The answer is firm- and market-specific, but industry benchmarks provide a useful starting frame.

According to the Journal of Accountancy 2025 close-cycle benchmark, firms that have successfully transitioned to subscription-based advisory billing report average monthly retainer fees of $1,500–$4,500 per client entity for mid-market advisory packages.

Typical CAS tier pricing structure in 2026:

These ranges are not suggested list prices — they are reference benchmarks. Your firm's pricing should reflect your market, your team's expertise, and your realization targets.

Worked Example: 12-Client CAS Portfolio, 3 Tiers

A 4-partner firm runs 12 CAS clients across 3 tiers: 5 at Foundation ($900/mo), 4 at Growth ($2,200/mo), and 3 at Advisory ($4,500/mo). Total monthly CAS revenue: $26,300. The firm used GoProposal to set pricing with a target 65% realization rate and a proposal.accepted webhook to trigger Ignition proposal delivery and Karbon job creation.

Before using a pricing tool, the same firm's CAS clients ranged from $600 to $5,800/month for similar work depending on which partner quoted them — a 30% variance. GoProposal's pricing calculator reduced that variance to under 10%, and average monthly retainer per client increased by $340 within two renewal cycles as underpriced clients were brought to market rates.

Where US Tech Automations Fits

For firms using any of these pricing tools, the orchestration gap is typically at the handoff — between proposal accepted and engagement active. The manual steps at that junction (creating the client record, assigning onboarding tasks, setting up billing, sending the welcome sequence) are consistently where the post-proposal window becomes a bottleneck.

US Tech Automations connects the proposal.accepted webhook from Ignition or Anchor to your downstream systems: client record creation in your CRM, onboarding task generation in Karbon or TaxDome, billing setup in Stripe or QBO, and a welcome email sequence via your email platform — all fired within minutes of signature.

The finance and accounting automation workflows include pre-built post-proposal flows for Ignition and Anchor integrations.

When NOT to use US Tech Automations: If your CAS onboarding consists of 3 steps that a single staff member handles in 20 minutes, the integration overhead is not worth the setup cost. The orchestration layer adds the most value when your onboarding involves 5+ systems, multiple staff handoffs, or 15+ steps per new client.

Decision Framework: Which Tool Fits Your Firm?

Common Mistakes in CAS Pricing Tool Adoption

• Launching a tool before defining your service tiers. The tool helps you deliver defined packages; it cannot define them for you. Spend 2–3 weeks on service design before tool configuration.

• Migrating existing clients to new pricing at the same time as tool launch. Combine a pricing increase with a new proposal tool and you'll face client resistance and internal confusion simultaneously. Launch the tool with new clients first.

• Skipping the engagement letter review. Ignition and Anchor ship with template engagement letters. Have your attorney review and customize these before going live — the templates may not reflect your state's requirements or your firm's standard terms.

• Not setting renewal automation. Every CAS pricing tool supports automatic renewal notifications. If you're not using this feature, you're leaving one of the highest-ROI automation opportunities on the table.

FAQ

What is CAS pricing software, and why do accounting firms need it?

CAS pricing software is a category of tools that help accounting firms build, quote, and sell advisory service packages to clients. It replaces ad hoc Word document proposals with structured tier-based pricing, engagement letter execution, and payment collection. Firms need it because advisory services don't fit hourly billing structures, and inconsistent pricing across partners is one of the most common growth barriers for CAS practices.

Is Ignition the same as Practice Ignition?

Yes. Practice Ignition rebranded to Ignition in 2022. The platform has continued to evolve since the rebrand. If you're evaluating tools today, the current Ignition platform is the relevant product.

Can these tools handle multi-entity clients?

Ignition and GoProposal both support multi-entity client structures, where a single client has multiple business entities with separate service packages. The setup requires defining each entity as a separate client record or using their multi-entity features if available. This is an area where the platforms have varying maturity.

How do CAS pricing tools integrate with QuickBooks Online?

Most CAS pricing tools connect to QBO to create or match invoices upon proposal acceptance. Ignition has a native QBO integration that creates recurring invoices directly in the client's QBO file. Anchor uses Stripe for payment processing, which can then be synced to QBO via a Stripe-QBO integration.

What is value pricing and how is it different from hourly billing?

Value pricing sets a fee based on the outcomes and value delivered to the client, rather than the hours spent. A CAS subscription at $2,500/month covers a defined set of deliverables regardless of how many hours the firm invests. Value pricing requires firms to define their service scope clearly — which is exactly what CAS packaging tools help with.

How long does it take to implement a CAS pricing tool?

For Ignition or Anchor, a focused team can configure the service library, tier structure, and proposal templates in 2–4 weeks. GoProposal requires additional setup for the pricing calculator configuration. Karbon Proposals, for existing Karbon users, can be operational in 1–2 weeks since the client records are already in place.

Should small solo accounting firms use a CAS pricing tool?

For solo practitioners with fewer than 5 advisory clients, a spreadsheet and a DocuSign template may be sufficient. The tipping point is typically 8–10 advisory clients, when pricing inconsistency and proposal creation time become noticeable pain points. At that point, Anchor's free base plan is a natural starting point.

CAS Revenue Impact: What Firms Report After Tool Adoption

According to the AICPA PCPS 2025 CAS Benchmark Survey, firms that use a dedicated proposal and engagement tool for CAS generate 23% more advisory revenue per client within 12 months of adoption compared to firms relying on manual proposals — primarily because standardized packaging reduces scope creep and underpricing.

CAS firms using proposal software average $2,800/month per client according to the AICPA PCPS 2025 CAS Benchmark Survey — versus $1,900/month for firms using manual Word-document proposals.

According to Karbon's 2025 Accounting Firm Operations Report, firms that automate the proposal-to-onboarding handoff reduce new-client activation time by an average of 8 business days — from the point of engagement letter signature to the first deliverable being produced.

Firms automating post-proposal onboarding reduce activation time by 8 business days according to Karbon's 2025 Accounting Firm Operations Report.

According to McKinsey's 2024 Professional Services Automation Report, professional services firms that adopt standardized pricing tools see a 15–20% improvement in partner realization rates within 18 months, as ad-hoc discounting is replaced by data-driven tier pricing.

Advisory firms using standardized pricing see a 15–20% realization rate improvement according to McKinsey 2024 Professional Services Automation Report.

CAS Tier Adoption Rates at Mid-Size Firms (2026)

The most common tier structure in 2026, based on AICPA PCPS data and vendor-published case studies:

Higher tiers carry higher margins because the advisory deliverables (cash flow analysis, board reporting, KPI dashboards) have a fixed delivery cost that scales less than the fee. Firms that do not have a dedicated pricing tool often undercharge for Advisory tier work because the scope feels hard to quantify.

Tool ROI Estimate: First-Year Numbers

Assumes 20 CAS clients averaging $1,320/month (blended across tiers), 10% revenue lift from pricing consistency. Even at half that uplift, first-year ROI is strongly positive for any of these tools.

Key Takeaways

• 62% of accounting firms use cloud workflow tools according to AICPA 2025 PCPS survey — but dedicated CAS pricing tools remain underutilized; most firms still quote advisory packages in Word or spreadsheets.

• CAS firms using proposal software average $2,800/month per client according to AICPA PCPS 2025 CAS Benchmark Survey — $900 more than manual-proposal firms.

• Karbon onboarding automation cuts activation time by 8 days according to Karbon's 2025 Accounting Firm Operations Report — closing the post-proposal gap that most platforms leave open.

• Ignition is the standard for firms with active advisory practices; Anchor is the free entry point; GoProposal is the pricing-intelligence layer; Karbon Proposals wins for existing Karbon users.

• The handoff from proposal accepted to engagement active is the highest-ROI automation point — US Tech Automations connects the proposal.accepted webhook to your CRM, billing, and onboarding systems in a single flow.

• For firms generating $500K+ in CAS revenue, an orchestration layer above the pricing tool recovers 8–12 hours of staff time per new client.

Conclusion

The right CAS pricing and packaging tool depends on where your firm is in the advisory transition. Anchor is the natural starting point for smaller firms testing the waters. Ignition is the standard choice for firms with an active and growing advisory practice. GoProposal solves the pricing consistency problem most directly. And for firms already invested in Karbon, the native proposals module removes one integration point.

What all of these tools share is a common gap: the handoff from proposal accepted to engagement active still requires manual coordination across systems in most firms. That gap is where automation pays off the most.
