CPA Firm Service Packages: How to Bundle Tax, Bookkeeping, and Advisory for Predictable Revenue

The Quick Answer

The most effective CPA firm package structure tiers clients by complexity and service depth: a Starter tier at $300–$500/month for simple sole proprietors and single-member LLCs, a Business tier at $600–$1,200/month for S-corporations and growing businesses, and a Growth tier at $1,500–$3,500/month for businesses doing $1M+ in revenue that need fractional CFO services. Each tier bundles a set of defined services — bookkeeping, payroll, tax preparation, quarterly planning calls — so clients know exactly what they're getting and you know exactly what you're delivering. Bundled monthly pricing generates 40–80% higher annual revenue per client than a la carte billing and dramatically reduces the mental overhead of tracking individual project invoices.

Starter Package Design ($300–$500/Month)

The Starter package is designed for sole proprietors, single-member LLCs, freelancers, and independent contractors in their first few years of business, typically earning $50,000–$200,000 in annual revenue. Services included at this tier: monthly bookkeeping in QuickBooks Online or Xero (categorization, reconciliation, and a monthly P&L report), quarterly estimated tax calculations and reminders, annual business tax return (Schedule C or Form 1065 for a simple partnership) included in the monthly fee, and email access with a 48-hour response time. This package explicitly excludes payroll (add-on at $75–$150/month), S-corporation preparation (upgrade to Business tier), and strategic planning calls (upgrade or charge separately). Price this at $375/month as your entry point — competitive enough to win clients from generalist CPAs and bookkeepers, while building a relationship from which upselling to higher tiers is natural. A client who starts on the Starter package and grows their business to $400,000 in revenue will organically need S-corporation election, payroll, and more sophisticated planning — at which point you move them to the Business tier without any awkward sales conversation.

Business Package Design ($600–$1,200/Month)

The Business package is your volume sweet spot — the tier that most small business owners need and will pay for consistently. Designed for S-corporations, C-corporations, and multi-member LLCs doing $250,000–$1,500,000 in annual revenue. Services included: monthly bookkeeping (reconciliation, P&L, balance sheet, AR/AP summary), owner-employee payroll processing (W-2 payroll, 940/941 filings), quarterly business tax planning calls (30 minutes each — review YTD financials, adjust estimated taxes, discuss material decisions), S-corporation or C-corporation annual tax return plus owners' personal returns included, and priority email access with a 24-hour response time. Real 2026 pricing examples: a single-owner S-corp with 3 employees and $500K in revenue — $800/month all-inclusive. A two-partner professional practice (consulting firm) with quarterly advisory calls — $1,100/month. An e-commerce business with inventory accounting complexity — $950/month. The Business package typically represents 50–60% of a solo CPA's total revenue because it hits the sweet spot of complexity, willingness to pay, and recurring engagement. Target 15–25 Business tier clients as the core of your practice.

Growth Package Design ($1,500–$3,500/Month)

The Growth package positions you as a fractional CFO, not just a compliance provider. Designed for businesses doing $1,000,000–$10,000,000 in annual revenue that need financial management beyond bookkeeping and tax preparation. Services included: all Business package services plus monthly financial statement review and management commentary (written memo on key metrics, variances, and risks), cash flow forecasting (13-week rolling cash flow model updated monthly), KPI dashboard (custom Google Data Studio or Fathom dashboard showing 6–10 key performance indicators), budget vs. actual variance analysis, ad-hoc advisory access (unlimited email, two 60-minute calls per month), and annual strategic planning session. Pricing: $1,500–$2,500/month for businesses at $1M–$3M in revenue; $2,500–$3,500/month for $3M–$10M businesses with more complexity. The key to selling Growth packages: quantify the ROI in the sales conversation. 'Companies at your revenue stage that work with a fractional CFO report finding $50,000–$150,000 in annual improvement through better pricing decisions, tighter collections, and expense optimization. At $2,000/month, you need to find $24,000 in annual improvement to break even — and most clients find that in the first quarter.' Target 3–7 Growth package clients as the highest-revenue layer of your practice.

Industry-Specific Package Examples

Generic packages are a starting point — the most effective CPA firm packages are tailored to the language and specific needs of a target niche. Real package examples by niche: E-Commerce Seller Package ($500–$900/month): Monthly bookkeeping with inventory accounting, multi-state sales tax compliance (managing nexus filings in 5–10 states), 1099-K reconciliation, and annual business and personal tax returns. Position this as 'complete accounting for Amazon FBA and Shopify sellers — no surprises at tax time.' Real Estate Investor Package ($600–$1,200/month): Monthly bookkeeping with property-level P&L by address, depreciation tracking, 1031 exchange advisory, cost segregation referral coordination, Schedule E preparation, and quarterly tax planning. S-Corp Owner Package ($650–$1,100/month): Payroll for owner-employee (reasonable salary determination and W-2 setup), quarterly estimated payments, S-corp 1120-S and personal 1040 preparation, and an annual S-corp health checkup call reviewing distributions, basis, and retirement plan options. Nonprofit Package ($400–$800/month): Monthly bookkeeping with fund accounting, Form 990 preparation, grant reporting support, and board financial reporting. Each of these packages uses the client's language ('Amazon FBA,' 'Schedule E,' 'Form 990') to signal deep niche expertise, which justifies premium pricing and dramatically reduces the sales friction compared to generic accounting packages.

Transitioning Existing Clients to Packages

If you inherit clients from a prior arrangement — or if you've been billing hourly and want to convert to packages — the transition requires a direct, confident conversation. Best practices: (1) Analyze each client's prior-year billings by category (bookkeeping hours, tax preparation, ad-hoc questions) and calculate what a package would cost at your new pricing. If the package price is 10–30% above their prior billings, most clients will accept it as a reasonable increase for more organized service; (2) Frame the transition as a benefit to the client: 'Starting January, I'm moving to a monthly package model. This means predictable costs for you — no bill surprises when you call with a question — and more proactive service from me, including quarterly planning calls we haven't been doing consistently'; (3) Send written notice in October or November for a January 1 effective date, giving clients time to adjust their budgets; (4) For clients where the package price would be significantly higher (50%+) than prior billings, offer a 90-day step-up — start at their current level and increase to full package pricing after the first quarter. This softens sticker shock while still transitioning them to your new model. Expect to lose 5–15% of a-la-carte clients who refuse to move to packages — these are typically your least profitable, most price-sensitive clients, and their departure improves your practice quality.

Billing, Invoicing, and Contract Terms for Package Clients

Once your packages are defined, the operational mechanics of billing are equally important. Monthly packages should be billed via ACH autopay or credit card on file (not monthly invoices) — billing friction is the primary reason for late payment, and autopay eliminates it entirely. CPACharge (cpacharge.com) handles card-on-file and ACH for CPA firms at 1.95% per card transaction and 1% per ACH, lower than general processors. Your service agreement for package clients should include: monthly package price and payment date (first of month), list of included services and explicit exclusions (e.g., 'amended returns billed separately at $350–$750'), a 12-month minimum commitment with 30-day written notice for cancellation, a price escalation clause ('Prices may be adjusted annually with 60 days written notice'), and a late payment provision (services paused for accounts more than 30 days past due). A signed service agreement protects both parties and dramatically reduces scope disputes. Use DocuSign or TaxDome e-signature to obtain signed agreements before beginning any work — unsigned engagement letters and service agreements are the #1 preventable cause of client disputes for solo CPAs.
