Prepare the cost categories
Use actual proposed commercial terms when estimating a specific program. The categories below are a planning structure, not a price list.
| Category | Planning question | Owner to involve |
|---|---|---|
| Customer benefit | What obligation follows from a qualifying purchase? | Commercial and finance |
| Program services | Which agreed charges apply to this program? | Procurement and finance |
| Communication and support | Who prepares messages and handles questions? | Marketing and customer service |
| Exceptions and returns | How do changes affect costs and workload? | Operations and finance |
| Measurement | Can costs be compared with return-adjusted results? | Finance and analytics |
Plan for uncertainty responsibly
Use documented participation assumptions and consider different levels of qualifying demand. Do not rely on customers failing to access their benefit to make a campaign affordable. Agree how the offer will be managed if demand differs from the forecast, consistently with its published terms.
Turn the budget into a decision
For a Shopify collection promotion, compare the full campaign cost with the result you intended to support, not gross sales alone. Review customer experience and the ability to honor the offer before expanding it.
