Women-owned bookkeeping firm Complete Controller has operated its cloud-based client accounting services platform from downtown San Diego's West Broadway corridor since 2008. The proprietary CAS-i system pairs each client with a dedicated bookkeeper and controller who reconcile bank feeds on a rolling basis, process payroll through an ADP integration, and generate the certificate-of-insurance documentation that commercial brokers at Cavignac require during annual workers' compensation premium audits. Complete Controller supports over 200 CPA firms nationally as a back-office provider, handling accounts-payable processing, accounts-receivable management, and full general-ledger maintenance under GAAP standards. The ADP payroll module automates quarterly 941 deposit tracking, W-2 generation, and California EDD withholding filings, producing the structured financial data that Storm Brain reconciles against client ad-spend budgets when co-managing shared accounts. Highest-tier engagements encompass multi-entity consolidated reporting with intercompany elimination entries and segment-level profit-and-loss analysis across disparate chart-of-accounts structures.
