+
+Domain Design: Consignment
+
+Version 1.0  |  Draft
+
+
+
+# 1. Overview
+
+The Consignment domain manages inventory that is owned by a third party (the consignor) and sold on their behalf by the store. The store earns a commission on each sale and owes the consignor the remainder. Consignment is common in music retail — individuals and local dealers bring in used instruments, vintage gear, or specialty items for the store to sell.
+
+Consignment items appear in the regular product catalog and POS — customers do not see any difference between store-owned and consignment inventory. The distinction is purely internal for accounting, commission tracking, and consignor settlement.
+
+
+
+# 2. Core Concepts
+
+## 2.1 Consignor
+
+A consignor is the person or business who owns the item. They are represented as an `account` in the system — they may also be a customer who buys from the store. Using the account entity means consignors have payment info on file for settlement payouts.
+
+## 2.2 Consignment Detail
+
+A `consignment_detail` record links a product to its consignor and defines the commission terms. If a product has a consignment_detail, it is consignment inventory. If not, it is store-owned.
+
+## 2.3 Commission
+
+The store's cut of a consignment sale. Defined as a percentage on the consignment_detail record. Example: 30% commission means the store keeps 30% of the sale price, the consignor receives 70%.
+
+## 2.4 Minimum Price
+
+Consignors may set a floor price below which the item cannot be sold without their approval. Stored on consignment_detail. POS enforces this — if a staff member attempts to sell below min price, the system warns and requires override.
+
+## 2.5 Settlement
+
+Periodic payout to the consignor for their sold items. Typically monthly. The store reviews all consignment sales for the period, deducts commission, and pays the consignor the balance.
+
+
+
+# 3. Database Schema
+
+## 3.1 consignment_detail
+
+Extension table on product — one record per consignment product.
+
+Column | Type | Notes
+id | uuid PK |
+product_id | uuid FK → product | The consignment item
+company_id | uuid FK → company | Tenant scoping
+consignor_account_id | uuid FK → account | Who owns the item

+agreement_date | date | When consignment agreement was made
+notes | text | Terms, special conditions
+is_active | boolean | False when item returned to consignor unsold
+created_at | timestamptz |
+
+## 3.2 consignment_settlement
+
+Records each payout to a consignor. Groups all consignment sales for a period.
+
+Column | Type | Notes

+company_id | uuid FK |
+consignor_account_id | uuid FK → account |
+period_start | date | Settlement period start
+period_end | date | Settlement period end
+total_sales | numeric(10,2) | Sum of sale prices for period
+total_commission | numeric(10,2) | Store's cut
+total_payout | numeric(10,2) | Amount owed to consignor (sales - commission)
+status | enum | pending, paid, cancelled
+paid_date | date | When consignor was paid
+paid_via | varchar | check, ach, cash, account_credit
+notes | text |
+created_by | uuid FK | Employee who created settlement
+created_at | timestamptz |
+
+## 3.3 consignment_settlement_line
+
+Individual sold items included in a settlement.
+
+Column | Type | Notes
+id | uuid PK |
+settlement_id | uuid FK → consignment_settlement |
+product_id | uuid FK → product |
+transaction_id | uuid FK → transaction | The sale transaction
+sale_price | numeric(10,2) | What it sold for
+commission_amount | numeric(10,2) | Store's cut on this item
+consignor_amount | numeric(10,2) | Consignor's payout on this item
+sold_date | date |
+created_at | timestamptz |
+
+
+
+# 4. Consignment Lifecycle
+
+Status | Description
+intake | Item received from consignor — product created, consignment_detail linked, inventory_unit created with status 'available'
+listed | Item is in the catalog and available for sale at POS
+sold | Item sold — commission calculated, included in next settlement
+settled | Consignor has been paid for the item
+returned | Item returned to consignor unsold — consignment_detail.is_active set to false, inventory_unit retired
+expired | Agreement period ended without sale — store contacts consignor to pick up or renew
+
+
+
+# 5. Key Workflows
+
+## 5.1 Consignment Intake
+
+- Consignor brings item to store (or store picks up)
+- Staff creates account for consignor if not existing
+- Staff creates product entry for the item (serialized, with description, photos)
+- Staff creates consignment_detail — links product to consignor account, sets commission %, min price
+- inventory_unit created with status 'available'
+- Consignment agreement printed or emailed — includes item description, commission terms, min price, store contact
+
+## 5.2 Consignment Sale
+
+- Item sold at POS like any other product
+- POS checks for consignment_detail on the product
+- If min_price set and sale price < min_price → warning, requires manager override
+- Transaction recorded normally
+- Consignment sale flagged for inclusion in next settlement
+- Journal entry differs from regular sale — see Accounting section
+
+## 5.3 Settlement
+
+- Manager runs settlement report for a period (e.g. monthly)
+- System groups all consignment sales by consignor for the period
+- For each consignor: total sales, total commission, total payout
+- Manager reviews and approves settlement
+- Settlement record created with line items
+- Consignor paid via check, ACH, cash, or account credit
+- Settlement marked paid with date and method
+
+## 5.4 Unsold Item Return
+
+- Consignor requests item back, or agreement expires
+- Staff updates consignment_detail.is_active = false
+- inventory_unit.status set to 'retired'
+- Product deactivated (is_active = false)
+- No financial transaction — item was never store property
+
+
+
+# 6. POS Integration
+
+- Consignment items appear in product search and catalog like any other item
+- No visual distinction to customers
+- Staff sees a "Consignment" badge on the product detail in POS
+- Min price enforced — POS blocks sale below min_price without override
+- Discounts on consignment items: commission calculated on actual sale price (after discount), not list price
+- Receipt shows the item like any other product — no consignment info visible to customer
+
+
+
+# 7. Accounting — Journal Entry Differences
+
+Consignment sales produce different journal entries than regular sales because the store never owned the inventory.
+
+## 7.1 Regular Sale (Store-Owned)
+
+Debit | Credit | Notes
+Cash/Stripe Clearing | Sales Revenue | Full sale price is revenue
+COGS | Inventory | Cost of item removed from inventory
+
+## 7.2 Consignment Sale
+
+Debit | Credit | Notes
+Cash/Stripe Clearing | Consignment Payable | Consignor's portion — liability until settled
+Cash/Stripe Clearing | Commission Income | Store's commission — this is your revenue
+(no COGS entry) | (no inventory entry) | Store never owned the item — no cost basis
+
+## 7.3 Consignment Settlement (Paying Consignor)
+
+Debit | Credit | Notes
+Consignment Payable | Cash/Bank | Liability cleared when consignor is paid
+
+### New Chart of Accounts Entries Needed
+
+Code | Account Name | Type | Notes
+2500 | Consignment Payable | Liability | Amounts owed to consignors for sold items
+4600 | Commission Income — Consignment | Revenue | Store's commission on consignment sales
+
+
+
+# 8. Reporting
+
+Report | Description
+Consignment inventory | All active consignment items — consignor, list price, days listed
+Consignment sales by period | Items sold, sale price, commission, consignor payout
+Unsettled consignment | Sold items not yet included in a settlement — amounts owed
+Settlement history | Past settlements by consignor — dates, amounts, payment method
+Commission analysis | Commission earned by period — identifies how much consignment contributes to revenue
+Aging report | Consignment items listed for X days without selling — candidates for return or price reduction
+Consignor statement | Per-consignor report — items listed, items sold, commission, payouts — printable/emailable
+
+
+
+# 9. Business Rules
+
+- Consignment items are always serialized (each is a unique item with a consignment_detail)
+- Commission calculated on actual sale price after discounts, not list price
+- Min price enforced at POS — override requires manager role
+- Consignor cannot be paid until settlement is approved by manager
+- Settlement cannot include items from future dates
+- Returned items generate no financial transaction — no revenue, no COGS
+- Consignment_detail is soft-deleted (is_active = false), never hard deleted — preserves history
+- Consignor account follows same rules as any account — soft-delete only, financial history retained
+- Price reductions on consignment items should notify consignor (future: notification system)
