The CAS firm model is the growth motion in accounting through 2026 and beyond. Compliance work pays the lights. Advisory work pays the ambition. Strkr ships a CRM core shaped around tiered service engagements, monthly close, advisory touchpoints, and the AICPA peer review audit requirements.
CAS firms sit at the intersection of compliance (monthly bookkeeping, tax, audit) and advisory (CFO services, cash flow planning, business coaching). The two sides have different cadences, different billing models, and different retention dynamics. A CRM built for a traditional CPA firm misses the advisory side. A CRM built for a management consulting firm misses the compliance side. The pain points below are what Strkr's onboarding team hears from CAS firms, from the 11-person boutique practice to the 80-staff regional firm.
A CAS firm typically runs three or four service tiers (Essentials monthly bookkeeping, Growth with quarterly review, Elite with monthly advisory conversation, Enterprise with embedded CFO). Each tier has a different cadence, deliverable mix, and billing rate. Generic CRMs cannot model this cleanly. Strkr ships service-tier picklists that drive the correct cadence, template library, and advisory frequency per client automatically.
CAS firms run fixed-fee monthly compliance work plus hourly advisory engagements. The partner needs margin visibility across both revenue streams with the ability to spot which clients are below target margin. Strkr prints hours-used-vs-budget per engagement and ties the time-tracker data through the webhook spec, which turns margin review from a quarterly surprise into a monthly conversation.
The economic value of advisory services is the scheduled conversation that actually happens. Firms that commit to monthly advisory and deliver three times a year lose the retention they sold. Strkr schedules advisory touchpoints as a cadence (monthly for Elite, quarterly for Growth) with Strkr AI drafting the prep memo. The conversation gets scheduled, prepped, and delivered.
CAS firms with CPA designation go through AICPA peer review every three years. The review examines workflow, client communication records, and quality control. A CRM that cannot show who touched this client, when, with what notes fails the review. Strkr's audit log records every record read, write, email sent, and AI prompt, with configurable retention per record type. The practice review conversation becomes a browse through the audit log instead of a scramble.
CAS firms sell advisory capacity that lives on the staff calendar. Over-selling leads to delivery slips and churn. Strkr's capacity view shows every staff advisor's committed hours per month across the client book. The partner sees who is at 90 percent capacity (sell carefully) and who has 20 percent slack (sell more). The firm stops guessing on capacity.
A typical CAS firm runs seven to eleven applications across production (QuickBooks, Xero), practice management (Karbon, Canopy), reporting (Jirav, Fathom), proposal (Ignition, Practice Ignition), and CRM. Strkr absorbs the practice management, proposal, and CRM layers and integrates with production through the webhook spec. Monthly tech cost drops by 30 to 55 percent.
Strkr ships a tunable CAS firm schema with Client, Service Tier, Engagement, Monthly Close, Advisory Touchpoint, Capacity Commitment, and Audit Record as first-class objects. The partner can rename or extend anything. The default lands close to where most CAS firms end up after two months of tuning.
A client in Strkr is an entity with service tier (Essentials, Growth, Elite, Enterprise), growth stage (startup, scaling, established, exit-planning), revenue range, and the accounting platform in use. The schema drives the correct close checklist depth, advisory touchpoint frequency, and template library per client.
Service tiers are first-class objects with the included deliverables (bookkeeping scope, tax preparation, audit, cash flow forecasting, advisory hours), the pricing model (fixed monthly, hourly cap, fixed plus hourly), and the delivery cadence. The partner can add new tiers (seasonal startup tier, legacy tier) without a schema rebuild.
An engagement ties to the client and defines scope (monthly bookkeeping, quarterly review, year-end tax, special project advisory). Each engagement carries its own fee structure, deliverables, and timeline. The engagement drives the task generation, the billing schedule, and the capacity commitment.
For clients with monthly bookkeeping in scope, a close period record spawns per client per month with status tracked (open, documents gathering, transaction coding, reconciliation, review, closed). The CAS firm sees close status across the full book of business in one view. Reopened periods surface in a separate queue.
Advisory touchpoints track the scheduled client conversations beyond compliance work. Monthly for Elite tier, quarterly for Growth tier, ad hoc for Essentials or Enterprise. Each touchpoint carries a prep memo, the conversation notes, and the follow-up actions. The firm sees advisory delivery against commitment at the client level and at the firm level.
Each staff advisor carries a capacity commitment per month (120 hours of advisory, 40 hours of compliance review). Client engagements consume commitment. The partner sees firm capacity utilization and spots over-sold or under-utilized staff. Capacity planning becomes a data conversation.
The audit record captures every record read, every record write, every email sent, every AI prompt, every document uploaded. Retention is configurable per record type to match AICPA peer review requirements (typically 90 days default, with longer retention on compliance notes and client communications). The peer review packet exports in one click.
A CAS firm cannot ship AI-drafted client communication that sounds like a chatbot. Strkr AI drafts in the professional, numbers-grounded tone a CAS partner would use. The jobs below are what shows up in every CAS firm deployment inside the first three weeks.
Strkr AI drafts the monthly recap from the closed engagement data: cash position, revenue trend, top expense categories, flagged items, next-month notes. The partner reviews and sends. For Elite tier clients the recap includes advisory observations. For Essentials clients the recap is numbers-only.
Before a scheduled advisory conversation Strkr AI drafts a prep memo with trend observations, cash runway, expense anomalies, and three suggested advisory topics. The partner spends 10 minutes preparing instead of an hour. The conversation lands with structure instead of winging it.
Strkr AI drafts the document chase email with specific items missing (bank statement for August, credit card statement for August, Venmo CSV), a friendly tone, and the close deadline. The partner approves and sends. 75 percent of day-7 chases get a response within 48 hours.
For annual engagement renewals Strkr AI drafts the renewal letter with current-year fee adjustment, scope confirmation, and signature link. The partner batch-approves 60 renewals in 25 minutes. The scope data comes from the engagement history, which keeps the renewal grounded in actual delivery.
For firms that run bookkeeping and refer tax to a separate preparer (or run bookkeeping and tax as separate teams) Strkr AI drafts the handoff summary with the closed-year financials, flagged items, and recommended tax notes. The handoff is clean and the client sees value from the CAS relationship.
After an intake call with a prospective CAS client Strkr AI drafts the summary email with scope restatement, tier recommendation, fee quote (monthly rate plus one-time setup if cleanup is required), onboarding timeline, and engagement letter draft attached. The partner approves and sends in under five minutes.
After an advisory conversation Strkr AI drafts a recap summarizing discussion, recommended actions with owners and dates, and the next scheduled touchpoint. The recap pulls from the conversation notes and the engagement history. The client gets a professional recap that justifies the advisory fee.
The CAS firm partner needs a cockpit view that shows practice health across compliance delivery, advisory delivery, margin, and capacity. Strkr's partner cockpit refreshes every 15 minutes and gives the partner the signals they used to pull together from four tools.
The cockpit shows client count at each service tier with the trend over the past 12 months. Partners see Essentials clients moving up to Growth, Growth clients moving to Elite, and the migrated revenue impact. The tier upgrade motion gets managed instead of hoped for.
The compliance delivery view shows close status across every client with monthly bookkeeping in scope. Red clients need a phone call this week. Yellow clients need one more chase. Green clients are on track. The partner sees practice-wide delivery health in one glance.
The advisory delivery view shows advisory touchpoints landing on commitment versus slipping. For Elite tier clients the view shows monthly delivery rate across the staff. For Growth tier the view shows quarterly delivery rate. The partner catches advisory delivery slips before clients complain.
The margin view shows revenue per client against hours consumed. For fixed-fee monthly engagements the view shows effective hourly rate (fee divided by hours). For hourly engagements the view shows margin against standard rate. Clients below target margin surface for scope re-negotiation.
The capacity view shows each staff advisor's committed hours versus available capacity. Over-committed staff flag for workload rebalancing. Under-utilized staff flag for additional engagement assignment. The partner stops sell-what-cannot-be-delivered patterns.
For CAS firms running an active new-business motion the pipeline view shows prospective clients by stage (introduction, discovery, proposal, signed, onboarding). The partner tracks lead sources (referral partners, inbound inquiries, outbound outreach) and sees which sources convert best.
The economic story for a CAS firm is the shift from compliance-heavy to advisory-heavy revenue mix. Advisory revenue carries 60 to 75 percent gross margin versus 35 to 45 percent for pure compliance. Strkr's advisory module is designed to accelerate this shift. The cards below are the actions firms take with Strkr to grow advisory revenue.
Strkr watches for signals that suggest an advisory conversation: cash runway dropping below 90 days, expense category spike over 30 percent, revenue drop over 20 percent, major capital expenditure, new entity formation. The signals surface on the client card with an AI-drafted conversation starter.
The tier upgrade motion runs on scheduled reviews (annually at engagement renewal, or triggered by specific signals). Strkr drafts the tier upgrade conversation grounded in the client's complexity signals. Firms running this motion typically move 15 to 25 percent of Essentials clients to Growth each year.
Strkr ships three default service tiers (Essentials, Growth, Elite) with suggested deliverable mixes. Firms customize per practice (industry-specific tiers for construction or healthcare, lifecycle-specific tiers for startups). The template library lets a firm design and ship a new tier in a day instead of a quarter.
The capacity view shows how much advisory capacity the firm can sell before over-commitment. The partner sees the number before quoting the next Elite tier engagement. The firm stops selling into capacity that does not exist and the retention gets protected.
Advisory engagements bill at their own rate (typically $200 to $500 per hour) distinct from the monthly fixed-fee bookkeeping. Strkr tracks the advisory revenue stream separately in reports so the partner sees compliance versus advisory as distinct revenue lines. The margin story becomes visible and defensible to firm leadership.
The audit log retains advisory conversation notes, recommended actions, and follow-up tracking per client. For firms going through AICPA peer review the advisory delivery evidence is a differentiator because it shows active practice management, not passive compliance.
Most CAS firms run seven to eleven applications across practice management, proposal, reporting, and CRM. The comparison below is Strkr's posture versus the typical stack applied to the same firm.

| Monthly close workflow | Native with 14-item checklist default. | Separate tool like Karbon or Canopy. |
| Advisory touchpoint cadence | Scheduled with AI prep memo. | Calendar reminder plus manual prep. |
| Capacity planning | Native with staff utilization view. | Separate tool or spreadsheet. |
| Proposal with signature | Native via Docs module. | Separate tool like Ignition. |
| Recurring billing | Native with Stripe sync. | Separate tool or manual. |
| AICPA peer review audit log | Native with configurable retention. | Partial per-tool. |
| AI drafting in firm voice | Trained on first 20 approved emails. | Generic or none. |
| Pricing basis | Flat per seat. | Per-tool subscriptions stack up. |
| Open API and integration surface | REST and GraphQL plus webhook spec. | Varies per tool. |
The playbooks below are patterns Strkr's onboarding team sees on CAS firm deployments, from boutique advisory practices to 80-staff regional firms.
A 14-staff boutique CAS practice in Minneapolis served 110 clients across Essentials, Growth, and Elite tiers. The partner ran practice management on Karbon, proposal on Ignition, and CRM in a shared sheet. Strkr onboarding ran an 18-business-day migration. The three applications collapsed to Strkr. Monthly tech cost dropped by 45 percent. Advisory delivery rate improved from 68 percent on commitment to 94 percent.
A 32-staff CAS firm in Seattle served 240 clients with a strong Growth tier concentration. The partner wanted a cross-firm view of advisory delivery and margin per client. Strkr onboarding ran a 24-business-day migration. The partner cockpit landed with cross-firm visibility while preserving staff autonomy over their book of business. Advisory revenue grew 32 percent in the 12 months after cutover.
A Denver CAS firm specializing in dental practice bookkeeping, tax, and advisory served 60 dental practices with HIPAA-adjacent data exposure. Strkr's business plan BAA closed the compliance gate. Strkr onboarding configured a dental practice sub-schema with practice-specific metrics (production per chair, hygiene revenue, insurance aging). The firm added 11 new dental practices in six months.
A 22-staff CAS firm in Chicago wanted to shift revenue mix from 70 percent compliance toward 50 percent fractional CFO work. Strkr's advisory cadence tracking, opportunity flagging, and tier upgrade motion drove the shift. 11 Growth tier clients moved to Elite tier (which included fractional CFO hours) over 11 months. Advisory revenue climbed from 22 percent of total to 38 percent in that period.
A 80-staff regional CPA firm with strong traditional audit and tax practices launched a CAS service line to grow advisory revenue. Strkr onboarding ran a 32-business-day migration for the CAS team only (the audit and tax teams stayed on their existing production tools). The CAS team grew from 11 clients at launch to 42 clients in the first year with the Strkr-managed cadence driving retention.

Strkr integrates with every major production and reporting tool through REST and GraphQL API plus outbound webhooks with HMAC signing. QuickBooks Online and Xero for production (bi-directional sync of chart of accounts and transaction data). Jirav and Fathom for reporting (pull of financial reports and KPI dashboards). Ignition and Practice Ignition for proposal workflow (for firms transitioning, Strkr Docs can absorb the proposal surface). For a 32-staff firm the integration surface typically takes an engineering sprint of two to three weeks.
Strkr's audit log records every record read, every record write, every email sent, every AI prompt, every document uploaded. Retention is configurable per record type to match AICPA peer review requirements (typically 90-day default, with longer retention on compliance notes, client communications, and advisory conversation records). The peer review packet exports in one click with the audit evidence organized by client, by engagement, and by date range. SOC 2 Type II is in progress with 2026-Q4 target. HIPAA BAA available.
Strkr prices flat per seat: $29 per user per month on Starter, $59 on Pro, $119 on Scale, with a 14-day trial. The AI Enhancement module is a $49 per month add-on. The typical CAS firm tech stack (Karbon at $59 per user, Ignition at $69 to $329 per month, Jirav at $150 per month, Fathom at $44 per month plus per-client fees, generic CRM at $45 per user) runs $200 to $350 per staff member per month. Strkr's Scale tier at $119 per seat replaces most of the stack with a 40 to 60 percent cost reduction.
Yes. Strkr's advisory module tracks advisory touchpoints as scheduled cadences (monthly for Elite tier, quarterly for Growth tier), surfaces advisory opportunities through signal flagging, drafts prep memos and recaps with Strkr AI, and reports advisory revenue separately from compliance revenue. Firms running the Strkr advisory motion typically grow advisory revenue 25 to 40 percent in the first year while compliance revenue stays flat or grows modestly. The margin story improves because advisory margin runs 60 to 75 percent versus 35 to 45 percent for compliance.
The role model gives each partner ownership of their book of business with full control over client data, workflow, and billing. The managing partner gets a configurable cross-firm view (read-only by default) for pipeline, close status, advisory delivery, and margin. Partners can share specific clients across the firm (for example a shared advisory engagement) through explicit record sharing. The audit log records every cross-partner view, which keeps the trust posture clean.
Strkr's import brings in the full client history (contact info, engagement history, note history, email history) with original timestamps preserved. For engagement letters and proposals stored as PDFs in a document management system (SharePoint, Google Drive, Dropbox) Strkr's attachment import brings the files in with their original paths and tags. The AI retrieval index sees the full history on day one, which means the first draft Strkr AI writes is grounded in actual client context, not a stub.
No sales call, no migration consultant, no four-month implementation. Enter your card, get 14 days of the full Pro tier, cancel any time before day 14 with zero charge. Spin up a workspace, import your CSV, and have something useful before lunch.
