Overview

Project Context

Client Scenario: "Mookie the Beagle Coach" – A startup offering professional pet training services and retail inventory sales, operating as an LLC taxed as an S-Corp.

The Objective: To design and implement a scalable accounting system in QuickBooks Online to manage hybrid revenue streams and maintain compliance.

My Role: Full-Cycle Bookkeeper responsible for initial setup, operational accounting, and month-end closing procedures.

Challenge

Technical & Operational Challenges

The business model required an accounting system that could handle distinct operational flows under one file:

Revenue BifurcationDifferentiating intangible training services (exempt from sales tax) from physical retail goods (subject to sales tax) at the point of sale.
Perpetual Inventory TrackingManaging inventory counts and Cost of Goods Sold (COGS) in real time to prevent stockouts and ensure accurate balance sheet valuation.
Equity ComplianceStructuring capital accounts to separate shareholder contributions from distributions, protecting S-Corp status under IRC rules.
Solution

System Implementation

1. Chart of Accounts Customization: Designed a custom Chart of Accounts tailored for S-Corps. Established unique parent/sub-account structures for shareholder equity, distributions, and multiple income streams to simplify tax reporting.

2. Sales Tax Center Configuration: Configured the QuickBooks Online Automated Sales Tax center. Integrated CDTFA rules to apply the correct California sales tax (9.0%) exclusively to retail transactions while keeping training services exempt.

3. Bank Feed Integration & Audit: Simulated bank feeds via CSV uploads. Matched external bank transactions to General Ledger entries to verify accuracy, executing bank reconciliations to bring variance to zero.
