A personal Excel/CSV data-cleaning demo: 8 fictional input rows become 7 after removing one exact duplicate. Zero stock is preserved; a missing price stays blank and is flagged. The original data is retained for comparison. This is a self-initiated example, not client work.
I can help with Excel/CSV cleaning, reconciliation and clear reports. We agree scope, price and delivery after reviewing a sample. First project: 50% off the agreed regular quote, with no future-order commitment.
Great approach to data cleaning! Preserving the original data while flagging missing values and removing only exact duplicates helps maintain accuracy and transparency. These small checks can make a big difference in reliable reporting.
I worked with a small business that needed a clearer picture of its profitability.
The challenge wasn't just recording transactions. It was making sure purchases, direct costs, and operating expenses were classified correctly.
When cost of sales isn't calculated accurately, gross profit can be misleading — and business owners may make pricing and purchasing decisions without knowing their true margins.
Here's what I focused on:
✅ Reviewing purchase transactions and cost classifications
✅ Separating direct costs from operating expenses
✅ Checking inventory and cost of goods sold, where applicable
✅ Improving the accuracy of gross profit reporting
✅ Making financial reports easier to understand and use
The biggest takeaway?
Revenue tells you how much you sold. Cost of sales helps you understand what those sales actually cost your business.
Accurate bookkeeping isn't just about keeping records up to date. It's about giving business owners numbers they can confidently use to make decisions.
