Custom Bookkeeping Solutions

Every business is different. Instead of forcing you into a rigid monthly package, we provide tailored, hourly bookkeeping support based entirely on the volume and complexity of your records. You only pay for the time required to keep your books accurate and up-to-date.

What Full-Charge Bookkeeping Means

For businesses: Full-Charge bookkeeping means handling the complete financial recording process: transaction entry, categorization, bank and credit card reconciliations, sales tax coordination, accounts payable/receivable, and period-end financial reporting.

For individuals & estates: Full-Charge bookkeeping means organizing income, expenses, accounts, assets, and supporting documents into a structured, reconciled record that is ready for tax preparation, mortgage underwriting, or estate administration.

Document and Data Services

When records are spread across paper statements, scans, spreadsheets, and old exports, Black Hills Accounting can organize and convert that data into a cleaner format for review or import. This includes document digitization, OCR-based extraction, combining multiple files, removing duplicates, correcting formatting issues, and preparing import-ready transaction files that reduce manual entry and cleanup time.
