Explanation
Analyzing product demand over the past 45 days involves reviewing historical sales data to understand how products performed during that period. This is especially useful for inventory management and e-commerce operations.
By looking at past 45-day trends, businesses can identify:
High-demand products that sold consistently
Slow-moving items that may need promotions or markdowns
Seasonal or cyclical patterns influencing sales
Emerging trends indicating new customer preferences
Why It Matters
Inventory Optimization: Knowing which products are likely to sell helps avoid overstocking or understocking.
Cost Efficiency: Minimizes storage costs and reduces capital tied up in unsold inventory.
Sales Forecasting: Helps e-commerce businesses predict demand and plan marketing campaigns or discounts.
Data-Driven Decisions: Enables smarter purchasing and replenishment strategies rather than relying on guesswork.
Example
If a business notices that a particular gadget sold 200 units in the last 45 days but only 50 units the previous 45 days, it indicates a rising trend. They can adjust inventory levels and marketing strategies accordingly.
Explanation
Account reconciliation is the process of ensuring that the balances in financial records match external documents, like bank statements, invoices, and receipts. Using historical data from the past 45 days allows accountants to:
Identify discrepancies between internal records and external transactions
Verify payments, receipts, and refunds
Ensure that all transactions are recorded accurately for financial reporting
Why It Matters
Accuracy in Financial Statements: Ensures that the reported revenue, expenses, and balances reflect actual business activity.
Fraud Prevention: Detects unauthorized transactions or errors in bookkeeping.
Compliance: Helps businesses meet regulatory and auditing requirements.
Cash Flow Management: Accurate records allow better tracking of receivables and payables.
Example
A company can take the last 45 days of bank statements and compare them with its internal records. If a payment of $500 appears on the bank statement but not in the internal ledger, it can be corrected immediately, preventing future reporting errors.
Explanation
Retroactive transaction analysis involves reviewing past financial transactions to identify patterns, discrepancies, or areas of improvement. This goes beyond simple reconciliation by providing insights into operational and financial performance.
Using data from the past 45 days, accountants and managers can:
Examine spending patterns and identify unnecessary costs
Track overdue payments or delayed collections
Assess the impact of previous business decisions on current financial health
Why It Matters

Operational Insights: Reveals inefficiencies or irregularities in the accounting and payment processes.
Audit Preparedness: Businesses are ready for audits if past transactions are accurately reviewed and verified.
Enhanced Accountability: Ensures that departments responsible for spending and revenue generation are held accountable for past actions.
