§ BOOKKEEPING
BOCA RATON · UPDATED MAY 2026
Books done monthly, built around your S-Corp.
Monthly bookkeeping, bank reconciliation, financial statements, and a month-end review call — for owner-operator businesses that need clean books and accurate K-1 numbers.
In short
Bookkeeping at KDM includes monthly transaction categorization in QuickBooks, bank and credit card reconciliation, accounts payable and receivable management, monthly financial statements, and a month-end review call with your assigned tax specialist. From $325/month for simple owner-operators, scaling with complexity. Smaller corporations can opt for the quarterly tier: $525/quarter plus $750 year-end tax filing. Payroll is a separate engagement.

§ 01
What monthly bookkeeping includes
- — Bookkeeping — categorize every transaction correctly, every month
- — Bank + credit card reconciliation (all business accounts)
- — Accounts payable management (review, code, schedule bill payments)
- — Accounts receivable (invoicing, aging reports, collection follow-up)
- — Sales tax filings (Florida DOR + any other states)
- — Monthly financial statements: P&L, balance sheet, cash flow
- — Month-end close review call with your assigned tax specialist
§ 02
Two engagement models — monthly or quarterly
Two tiers, two cadences, two prices. Most clients land on monthly. Smaller corporations with lower transaction volume often prefer the quarterly tier — same close discipline, less frequent, bundled with the year-end return.
- — Monthly bookkeeping ($325/mo) — for owner-operators and S-Corps with ongoing AR/AP and monthly financial reporting needs. Books close every month; clean P&L within 7 business days of month-end.
- — Quarterly bookkeeping ($525/quarter) — for smaller corporations with lower transaction volume. We close the books each quarter and prepare the year-end tax return as a bundled offering ($750). Total annual cost: $2,850 (4 × $525 + $750).
- — Both tiers exclude payroll (separate engagement, see Payroll Services) and tax preparation beyond the year-end return for quarterly clients.
§ 03
Why monthly matters
Annual bookkeeping is like checking your bank balance once a year — you're flying blind and can't act on anything you see. Monthly bookkeeping gives you real-time financial awareness. Clean monthly books also:
- — Make tax filing fast and accurate (no March bookkeeping cleanup)
- — Keep you compliant (sales tax, payroll tax, estimated tax)
- — Qualify you for business loans and lines of credit
- — Let you spot problems (declining margins, cash leaks) in month 2 — not month 12
- — Build a sale-ready business (buyers require clean books)
§ 04
For different business types
The right accounting system depends on your industry, size, and complexity.
- — Service businesses (consulting, legal, medical): project/client-level P&L
- — Retail/e-commerce: inventory management + COGS tracking
- — Real estate: property-level reporting, cost segregation
- — Construction: job-costing, percentage-of-completion
- — Restaurants: daily sales reporting + food cost ratios
- — Professional practices: owner-compensation reporting
§ 05
Advisory, not just bookkeeping
Data without interpretation is just numbers. Our monthly close includes a 30-60 minute call where we walk through what the financials mean: what's trending, what's changed, what decision you should make this month based on what the numbers say.
§ 06
Books that feed your S-Corp return
For S-Corp owner-operators, the books are the foundation of an accurate 1120-S and a defensible reasonable-compensation memo. We close every month so the K-1 numbers are right the first time, the §199A QBI computation has clean inputs, and the basis schedule stays current. See S-Corporation Tax for how the two engagements fit together.
§ Pricing
Flat fees. No hourly surprises.
Bookkeeping is flat-fee. Two engagement models — monthly (most clients) or quarterly (smaller corporations). Monthly pricing scales with transaction volume and complexity.
| Item | Complexity | Typical flat fee |
|---|---|---|
| Monthly bookkeeping — solo or micro business | Up to ~50 transactions/month, monthly close | From $325/mo |
| Quarterly bookkeeping (smaller corporations) | Lower volume, quarterly close | $525 / quarter |
| Year-end tax filing (quarterly clients) | 1120-S or 1120 year-end return, bundled with quarterly tier | $750 flat |
| Monthly bookkeeping — small service business | ~100 transactions/month, sales tax | $650–$1,100/mo |
| Monthly bookkeeping — growing business | ~250 transactions/month, sales tax, multi-account | $1,200–$2,200/mo |
| Multi-entity or multi-location | Quoted per file | From $2,500/mo |
| One-time QuickBooks cleanup | Catch-up bookkeeping + reconciliation | $1,500–$6,000 |
