When financial records are handled through spreadsheets, paper receipts, or traditional bookkeeping apps that require manual work, errors become inevitable and costly.
AI accounting software like Adam by Tyms removes the manual bottlenecks that cause those errors. Adam automatically imports your transactions, categorizes expenses, detects duplicates, and generates tax-ready financial reports instantly.
Instead of cleaning up messy books every tax season, you get clean and accurate financial records all year, making taxes, audits, and business decisions much easier..
What tax errors are common with manual bookkeeping?
Manual bookkeeping commonly leads to mistakes such as:
- Misclassified expenses
- Duplicate entries from copy-paste errors
- Missing transactions
- Inaccurate financial statements
