Modeling COGS and Customer Impacts for Tariff-Driven Planning
For businesses where Cost of Goods Sold (COGS) is a key metric, such as manufacturing, retail, or distribution, effective budgeting and forecasting are critical for profitability amid tariffs and global competition.
Understanding COGS and Tariffs
COGS includes direct costs like raw materials, labor, and production overhead, directly affecting gross margins and pricing. Tariffs increase costs for imported materials or overseas competitors, creating challenges and opportunities. Budgeting tools integrated with accounting platforms streamline planning, model tariff impacts, evaluate supplier changes, and identify market advantages. This article outlines how COGS-based businesses can use these tools to address tariff-driven challenges strategically.
Benefits of Budgeting Tools
Cloud-based budgeting tools integrate with platforms like QuickBooks and Xero, offering real-time data, scenario modeling, and visual outputs. Key features include:
- Real-Time Data Sync: Tracks costs accurately via accounting integration.
- Scenario Modeling: Evaluates tariff impacts, pricing adjustments, or supplier changes.
- Dashboards: Visualizes trends, margins, and budget variances.
- Rolling Forecasts: Adapts budgets to market and tariff changes.
These capabilities support proactive COGS management and strategic decision-making.
Steps to Prepare for Planning and Budgeting with Reach Reporting
1. Build a Base-Level Budget with Row Drivers

A base-level budget establishes a foundation for COGS modeling. Row drivers automate data population, ensuring consistency across financial statements.
Action: Create multiple budgets. Apply the “Based on Previous Period” row driver to COGS accounts (e.g., raw materials) to populate prior-year actuals. Use a linked datasheet to incorporate tariff rates, setting a baseline for supplier costs.
Benefit: Automated row drivers reduce manual errors, aligning financial statements to accurately model supplier or pricing changes.
2. Analyze Historical COGS Trends
Historical COGS trends inform scenario planning by identifying cost drivers, such as supplier price shifts or tariff impacts, using automated settings.

Action: Review COGS accounts in the base budget, populated by the “Based on Previous Period” driver. Add a linked datasheet for historical supplier costs or tariff rates, and use comments to note trends (e.g., 10% material cost increase due to tariffs).
Benefit: Historical context supports realistic COGS forecasts, guiding supplier or pricing adjustments.
3. Create Budget Scenarios for Pricing and Supplier Changes


Budget scenarios model the impact of COGS changes on profitability and customer numbers.
Action: Duplicate the base budget for two scenarios. Scenario 1: Pricing Adjustment – Model a 10% price increase in a linked datasheet to offset tariff-driven COGS rises, applying a “Linear Growth” forecast algorithm to sales rows, assuming a 5% customer reduction. Scenario 2: New Supplier – Create a subdivided budget by product line, using a “Fixed Amount” row driver for a 15% COGS reduction from a domestic supplier, then adjust sales for a 5% price cut, projecting a 10% customer increase. Document assumptions with comments.
Benefit: Scenarios quantify trade-offs (e.g., higher prices vs. customer retention), with 3-way forecasting updating cash flow and balance sheet impacts.
4. Compare Scenarios in a Dashboard
Dashboards consolidate scenarios for comparison, highlighting COGS, profitability, and customer impacts across financial statements.

Action: Build a dashboard comparing the base budget, pricing adjustment, and new supplier scenarios. Include metrics like COGS as a percentage of revenue, net profit margin, and customer numbers. Use a table for P&L and cash flow variances and a chart for customer count changes (e.g., -5% for pricing, +10% for supplier). Enable real-time sync for actuals.
Benefit: Dashboards deliver clear insights, supporting data-driven decisions on pricing, suppliers, and customer strategies while aligning with liquidity goals.
5. Model Competitor Tariff Impacts
Tariffs can raise competitors’ COGS, creating market share opportunities. Multi-year budget grouping models competitor price hikes and customer acquisition.

Action: Group budgets across years to model competitors raising prices by 5-15% due to tariffs. Use an “Update with Actuals” row driver to adjust marketing budgets, targeting a 12% customer increase. Add data to the dashboard.
Benefit: Modeling informs proactive budgeting, with dashboards clarifying customer growth and cash flow.
6. Maintain Flexibility with Rolling Forecasts
Rolling forecasts adapt budgets to changing conditions using forecast conversion and automated drivers.

tariff rolling forecast
Action: Convert a budget to a forecast, selecting the forecast month. Use an “Update with Actuals” driver to adjust COGS for supplier or pricing changes, modeling customer impacts (e.g., 8% growth from lower prices) in a linked datasheet. Update the dashboard with forecast data.
Benefit: Rolling forecasts ensure projections remain current, optimizing COGS, pricing, and customer acquisition.
Turning Tariffs into Strategic Advantages

While many businesses react to tariffs with uncertainty, proactive planning with Reach Reporting transforms challenges into opportunities. By centralizing COGS data, modeling scenarios, and comparing outcomes, businesses can optimize pricing, suppliers, and market positioning. Accountants become strategic partners, guiding clients through economic shifts with data-driven insights. In a stable economic environment, those who leverage budgeting and forecasting will thrive while others hesitate.
