What it does

Vendor plans give one commission per plan, and category fees one percent per category. Real marketplaces need more: a negotiated rate for a key vendor, a lower rate on expensive electronics, a launch promo for a new category, volume tiers, or a minimum fee per order.

Advanced Commission Rules adds these rules on top of your plans. Products without a matching rule keep the plan commission, so you only describe the exceptions.

What it changes for your store

  • 8 condition types per rule. Vendor, plan, category with subcategories, product, unit price, order subtotal, monthly vendor sales and order dates.
  • Percent + fixed amount per order, with minimum and maximum caps.
  • Shipping, taxes and discounts in or out of the base, per rule.
  • A simulator shows the result before you save.
  • Earlier orders never change; an explicit tool recalculates selected orders.
  • 0 core file changes; vendor balances, Accounting and payment splits use the result.

How it works

Admin

Open Vendors, Commission rules and add rules. Each product of a vendor order gets the most specific matching rule (or the lowest priority number, as you choose). Test any product in the simulator.

Order

When an order is placed, the vendor payout gets the rule-based commission. The order page shows the calculation per rule and product; edits and refunds follow it.

Vendor

The vendor panel gets a read-only My commission rates page. The report compares rule and plan commission and exports CSV.

Features

  • Rules by vendor, vendor plan, category (with subcategories), product, product price range, order subtotal range, monthly vendor sales and date range
  • Percent and fixed amount per order, minimum and maximum commission per order
  • Most-specific-wins or priority-order resolution, documented and visible in the simulator
  • Per-rule commission base: shipping, taxes, before or after discounts
  • Works on top of Vendor plans and Commissions by category; products without a rule keep those rates
  • Vendor balance, Accounting, order pages and payment splits use the rule-based commission
  • Order edits and refunds adjust the commission; earlier orders are never recalculated by themselves
  • Explicit recalculation tool with preview, adding adjustment entries instead of rewriting history
  • Commission simulator, per-order breakdown, commission report and CSV export
  • Read-only "My commission rates" page for vendors, with privileges for admin staff
  • No core file changes, clean uninstall that leaves earlier commissions intact
