Starting a CAS practice is not simply adding ‘advisory’ to a service list. The scalable version requires a defined target client, standardized delivery, recurring pricing, clean data, dedicated ownership and a repeatable way to turn financial information into decisions.
Step 1: choose the client profile
Pick clients with recurring needs that your firm can serve consistently. Industry focus can improve standardization because the same KPIs, integrations, reporting cadence and business questions repeat across clients.
Step 2: define three service levels
- Foundation: bookkeeping/close and baseline reporting
- Controller: close ownership, management reporting, cash-flow and process support
- Advisory/CFO: forecasting, KPI interpretation, planning and decision support
Step 3: design the delivery workflow
Document onboarding, data collection, monthly close, quality review, reporting, advisory meetings and follow-up. Use the CAS Guide, Bookkeeping Client Onboarding Checklist and Monthly Bookkeeping Checklist as starting points.
Step 4: price for recurring economics
Use fixed recurring or packaged pricing where scope is sufficiently standardized. Build a cost and margin floor, then price for complexity and value. The Bookkeeping Pricing Calculator can help translate delivery assumptions into a minimum sustainable monthly fee.
Step 5: assign dedicated ownership
CAS clients need consistency. Define who owns the relationship, close, review, advisory preparation and meeting follow-up. Avoid a model where responsibility moves informally between whichever staff member has capacity that week.
Step 6: build the technology stack
Standardize the systems you will support whenever possible. For your own practice operations, connect CRM, workflow, time, WIP, billing and reporting so you can see whether CAS is growing profitably. PracticeERP’s features are designed around that firm-level operating layer.
Step 7: launch with a pilot cohort
Start with a manageable group of existing clients that fit the target profile. Track effort, exceptions, client questions and meeting value for several cycles. Use that data to refine scope, onboarding, pricing and staffing before scaling sales.
Step 8: measure the practice
Track recurring revenue, growth, client retention, average fee, gross margin, net client fees per professional, close cycle time and advisory attach rate. The Accounting Firm KPI Guide provides a broader firm scorecard.
