Accurate books aren't just about recording transactions—they're about understanding the numbers, investigating discrepancies, and keeping financial information organized and reliable. I'm a CPA with extensive accounting experience, including recent hands-on experience supporting a U.S.-based construction company. My background combines accounting knowledge with practical experience in QuickBooks Online, reconciliations, expense and bill recording, financial data cleanup, Excel, and construction-related accounting. What I can help with: 🔹 QuickBooks Online bookkeeping & transaction review 🔹 Bank & credit card reconciliations 🔹 Bills, expenses & supporting-document review 🔹 Construction bookkeeping & job-costing support 🔹 Accounting cleanup & discrepancy investigation 🔹 Financial reporting & account analysis 🔹 Excel-based reconciliation and data analysis 🔹 Process documentation and bookkeeping workflow improvements My working style is simple: accurate, organized, proactive, and accountable. When something doesn't make sense, I investigate it and ask questions rather than guessing. If you're looking for someone who can bring both accounting knowledge and careful hands-on execution to your books, I'd be happy to help.
