A PrestaShop Promotion Launch Checklist for Agencies

# A PrestaShop Promotion Launch Checklist for Agencies Agencies inherit promotion complexity across clients, shops, currencies, and customer groups. A reliable launch process must make implicit interactions visible before anyone changes production rules. First, freeze the campaign brief into testable inputs: time window, eligible shop, currency, country, group, carrier, products, minimum quantity, minimum value, expected stack, and forbidden stack. Include a merchandise cost basis for each representative cart. “Twenty percent off VIP orders” is not enough when a catalog rule already reduced the same products. Second, review the full current scope. Look for expired rules that remain active, broad catalog rules, cart-rule compatibility restrictions, equal priorities, fixed-amount reductions in another currency, and product conditions with large value sets. A promotion that overlaps dozens of other rules deserves a performance review even when the math is correct. Third, replay deterministic scenarios. Run boundary totals immediately below and above every minimum. Repeat for important customer groups, countries, currencies, carriers, products, and quantities. Trace applied and skipped steps rather than checking only the final number. Compare the discounted result to cost basis and escalate any below-cost scenario. Finally, verify actual checkout behavior in a disposable clone, capture evidence, and obtain approval before editing live promotions.
