| 6 | # Dynamic Pricing for Ecommerce |
| 7 | |
| 8 | Turn seller-approved economics and trusted signals into a bounded repricing system with explicit rules, approvals, monitoring, and a kill switch. |
| 9 | |
| 10 | ## Installation |
| 11 | |
| 12 | ```bash |
| 13 | npx skills add nexscope-ai/eCommerce-Skills --skill dynamic-pricing-ecommerce -g |
| 14 | ``` |
| 15 | |
| 16 | ## Capabilities |
| 17 | |
| 18 | - Define SKU eligibility for automatic, approval-required, or manual repricing. |
| 19 | - Calculate contribution-safe floors and commercially justified ceilings. |
| 20 | - Select demand, inventory, competitor, season, and promotion signals without treating noisy observations as facts. |
| 21 | - Create deterministic rule matrices with bounded price steps, cooldowns, and conflict precedence. |
| 22 | - Simulate normal, downside, promotion-stack, stockout, and price-war scenarios. |
| 23 | - Design approval, audit-log, rollback, anomaly-breaker, and emergency-stop controls. |
| 24 | - Produce a staged platform implementation and measurement plan without enabling live changes. |
| 25 | |
| 26 | ## Usage Examples |
| 27 | |
| 28 | ```text |
| 29 | Design safe Amazon repricing rules for these 200 SKUs without starting a price war. |
| 30 | ``` |
| 31 | |
| 32 | ```text |
| 33 | Create an inventory-aware dynamic pricing plan for my Shopify store. |
| 34 | ``` |
| 35 | |
| 36 | ```text |
| 37 | Which products can be auto-repriced, and which should always require approval? |
| 38 | ``` |
| 39 | |
| 40 | ```text |
| 41 | Audit these existing repricing rules for margin, promotion, and rollback risks. |
| 42 | ``` |
| 43 | |
| 44 | ## Inputs and Collection |
| 45 | |
| 46 | Use seller-supplied and inspected evidence first. Collect: |
| 47 | |
| 48 | - SKU, variant, channel, marketplace, currency, tax treatment, fulfillment method, and lifecycle stage; |
| 49 | - current price, realized selling price, list or compare-at price, coupons, promotions, bundles, and discount-combination rules; |
| 50 | - COGS, inbound freight, duties, packaging, fulfillment, payment, referral, affiliate, ad, return, and other variable costs; |
| 51 | - target contribution dollars or margin, approved floor, approved ceiling, and brand or MAP constraints; |
| 52 | - inventory on hand, inbound stock, sell-through, age, weeks of cover, replenishment lead time, and stockout risk; |
| 53 | - timestamped traffic, orders, units, realized price, conversion where available, cancellations, and returns; |
| 54 | - comparable competitor offers with variant, pack size, seller, fulfillment, availability, delivered price, source, and capture time; |
| 55 | - current repricing tool, platform capabilities, rule cadence, account permissions, approvers, and business objective. |
| 56 | |
| 57 | If required economics or authorization details are missing, ask one consolidated follow-up. If they remain unavailable, design a provisional system but mark affected floors, rules, and automation decisions as blocked. |
| 58 | |
| 59 | ## Workflow |
| 60 | |
| 61 | ### 1. Establish the Evidence Boundary |
| 62 | |
| 63 | List the exports, pages, cost sheets, platform settings, and seller facts actually inspected. Label each material input: |
| 64 | |
| 65 | - **Confirmed:** supported by inspected evidence. |
| 66 | - **Assumption:** an explicit scenario placeholder, not an observed fact. |
| 67 | - **Unknown:** missing information that blocks reliable automation. |
| 68 | |
| 69 | Do not invent demand, competitor history, costs, fees, elasticity, conversion, or platform capability. A visible competitor price is a point-in-time observation, not a durable market signal. |
| 70 | |
| 71 | ### 2. Calculate Economic Guardrails |
| 72 | |
| 73 | Use realized seller-funded economics: |
| 74 | |
| 75 | ```text |
| 76 | Net Revenue = Selling Price - Seller-Funded Discounts - Refund Allowance |
| 77 | Contribution $ = Net Revenue - COGS - Variable Selling Costs |
| 78 | Contribution % = Contribution $ / Net Revenue |
| 79 | ``` |
| 80 | |
| 81 | When percentage fees apply to selling price: |
| 82 | |
| 83 | ```text |
| 84 | Price Floor = (Unit Cost + Fixed Variable Costs + Target Contribution $) / (1 - Variable Fee Rate) |
| 85 | ``` |
| 86 | |
| 87 | Model base, high-return, high-ad-cost, promotion-stack, and fee-change cases. Keep a contractual or legal minimum separate from the calculated economic floor. Define a ceiling from value, reference-price, policy, and customer-trust constraints; do not create artificial scarcity or an inflated reference price. |
| 88 | |
| 89 | ### 3. Classify SKU Automation Eligibility |
| 90 | |
| 91 | Assign each SKU to one control tier: |
| 92 | |
| 93 | | Tier | Appropriate when | Required control | |
| 94 | |---|---|---| |
| 95 | | Auto-eligible | reliable economics, stable identifier, trusted signals, reversible changes | bounded rules, logs, alerts, kill switch | |
| 96 | | Approval-required | launch, high margin risk, large price step, strategic product, sparse data | human review before publish | |
| 97 | | Manual-only | missing costs, MAP/legal ambiguity, bundles, custom products, unstable feed, sensitive category | analysis only | |
| 98 | |
| 99 | Default uncertain SKUs to the more restrictive tier. Automation convenience is not evidence that a SKU is safe to automate. |
| 100 | |
| 101 | ### 4. Select and Validate Signals |
| 102 | |
| 103 | For every signal, record source, freshness, coverage, failure mode, and fallback: |
| 104 | |
| 105 | - **Competitor:** only normalized, comparable, available offers; reject mismatched packs, used items, suspicious sellers, and stale captures. |
| 106 | - **Demand:** use observed seller traffic and orders with timestamps; separate price effects from ads, content, seasonality, and stock. |
| 107 | - **Inventory:** use on-hand, age, sell-through, lead time, and replenishment risk; do not treat a feed error as surplus or scarcity. |
| 108 | - **Time or event:** use scheduled windows with explicit start, end, timezone, and promotion interaction. |
| 109 | - **Own promotion:** distinguish seller-funded from platform-funded incentives and confirm whether discounts stack. |
| 110 | |
| 111 | Never use protected personal characteristics or opaque customer vulnerability to set individualized prices. Avoid price-gouging, collusion, and discriminatory outcomes. |
| 112 | |
| 113 | ### 5. Build the Rule Matrix |
| 114 | |
| 115 | Each rule must specify: |
| 116 | |
| 117 | | Field | Requirement | |
| 118 | |---|---| |
| 119 | | Scope | channel, market, SKU group, exclusions | |
| 120 | | Trigger | measurable condition and minimum duration | |
| 121 | | Evidence gate | freshness and completeness required | |
| 122 | | Action | hold, increase, decrease, or request approval | |
| 123 | | Step limit | maximum absolute and percentage change per action | |
| 124 | | Floor/ceiling | seller-approved hard bounds | |
| 125 | | Cooldown | minimum time before another change | |
| 126 | | Precedence | which rule wins when triggers conflict | |
| 127 | | Approval | automatic, reviewer, or manual-only | |
| 128 | | Recovery | revert target and anomaly response | |
| 129 | |
| 130 | Use deterministic rules first when data is sparse or explainability matters. An algorithmic recommendation still requires the same economics, input-quality, authorization, and rollback gates. |
| 131 | |
| 132 | ### 6. Simulate Before Enabling |
| 133 | |
| 134 | Replay or model at least: |
| 135 | |
| 136 | - ordinary demand and competitor movement; |
| 137 | - a competitor stockout or feed disappearance; |
| 138 | - an extreme competitor price or mismatched offer; |
| 139 | - promotion and coupon stacking; |
| 140 | - a high-return or fee-change downside; |
| 141 | - low inventory, excess inventory, and replenishment delay; |
| 142 | - repeated undercutting that could create a price loop; |
| 143 | - stale or unavailable input data. |
| 144 | |
| 145 | Report rule firings, resulting price, contribution, approval path, clipped actions, and stop conditions. If reliable historical data is unavailable, use clearly labeled synthetic boundary cases rather than pretending to backtest. |
| 146 | |
| 147 | ### 7. Design Governance and Rollback |
| 148 | |
| 149 | Require: |
| 150 | |
| 151 | - least-privilege account access and an authorized owner; |
| 152 | - versioned rules, change reason, actor, timestamp, old price, new price, and signal snapshot; |
| 153 | - alerts for floor or ceiling contact, excessive frequency, missing data, feed mismatch, and abnormal price movement; |
| 154 | - a circuit breaker that freezes or reverts changes when thresholds are breached; |
| 155 | - a documented manual override and emergency stop; |
| 156 | - current platform, marketplace, legal, tax, MAP, and consumer-protection review. |
| 157 | |
| 158 | The system must fail closed: when a required signal, cost, rule, or authorization is missing, hold the last approved price or route to review. |
| 159 | |
| 160 | ### 8. Stage the Rollout and Measurement |
| 161 | |
| 162 | Start in observe-only mode, then shadow recommendations, then a small reversible pilot, and only then expand approved automation. Capture the pre-change baseline and monitor realized price, units, net revenue, contribution dollars, conversion where reliable, return rate, promotion cost, inventory, rule frequency, overrides, errors, and competitor response. |
| 163 | |
| 164 | Define keep, revise, pause, and revert gates before launch. Do not attribute changes to price alone when traffic, ads, content, assortment, stock, seasonality, or promotions changed simultaneously. |
| 165 | |
| 166 | ## Domain Rules |
| 167 | |
| 168 | - Never enable, edit, or publish a live price or repricing rule without explicit authorization. |
| 169 | - The seller-approved hard floor and ceiling override every signal and model output. |
| 170 | - Do not automatically follow the lowest visible offer or create an undercutting loop. |
| 171 | - Keep platform-funded and seller-funded discounts separate and model discount stacking. |
| 172 | - Treat MAP and resale-price restrictions as legal or contractual matters requiring jurisdiction-specific review. |
| 173 | - Do not recommend collusion, deceptive reference prices, price gouging, or discriminatory personalized pricing. |
| 174 | - Use observable rules, logs, approvals, rollback, and a kill switch for every automated scope. |
| 175 | - Recheck current platform rules and account capabilities before implementation. |

| 242 | - Sparse or confounded historical data cannot prove demand response, elasticity, or causality. |
| 243 | - Public competitor data can be stale, incomplete, non-comparable, or erroneous. |
| 244 | - Dynamic pricing does not guarantee conversion, Featured Offer placement, contribution, revenue, or market share. |
