Match barcodes and channel listings deliberately

Barcode records map recognized identifiers to the intended product and unit. A label does not grant a new stock identity or prove that an item was physically received, sold or returned.

Channel product mappings retain the channel’s listing identity and the canonical SKU it represents. Conflicting or missing mappings require review before they generate operational quantities. A listing change cannot redirect a previously accepted order line to another product without an approved change.

• Keep product, variant and channel identities distinct.
• Resolve each selling identifier to the right SKU and unit.
• Preserve mappings used by historical orders.
• Investigate ambiguous identifiers before using them for stock work.

Keep buying, selling and stocking units aligned

Products may be bought or sold in packs while stock is held in individual units. A reviewed conversion establishes how transaction quantity becomes base quantity. Two packs of six reserve twelve base units, not two or an assumed quantity from the product description.

The transaction keeps the conversion version it used. Later pack changes cannot rewrite received quantities, finished output, customer handovers or the units eligible for return.

Conversions must be meaningful for the particular product. Quantities from different SKUs cannot be added as though they were one interchangeable item, including the components that go into an assembled kit.

Preserve net amounts through partial work

Line discounts and any allocated order discount reduce the agreed net amount once. The invoice and credit use their eligible share of that accepted amount instead of subtracting the original discount again.

Partial quantities retain deterministic rounding. When an agreed net total is split across several fulfillments, the final eligible allocation receives the remaining cents so the parts still reconcile to the agreement.

Tax treatment and its effective rate evidence remain separate from the product’s display price. Missing tax or currency evidence cannot be replaced with zero. A valid zero rate or zero price needs its explicit reviewed basis, not a fallback caused by missing data.

Introduce changes without rewriting history

Product, unit, mapping and pricing changes follow the relevant independent domain review. Preserve before-and-after content, effective boundaries and affected unexecuted work. Posted stock and accepted commercial history remain traceable to the versions actually used.

Production recipes and standards have their own technical and finance authority. Editing a retail description cannot change the component issue, finished quantity or cost of an already released job.

A physical kit and a sales grouping also need different treatment. Actual assembly consumes materials into WIP and receives finished stock; simply grouping sellable items must not produce that same kit balance a second time.

Earn rewards from completed eligible purchases

LoyaltyPrograms retains the effective promotional rules and independent commercial and finance activation. Members have verified customer identities rather than a shared walk-in account. Eligible paid and supplied purchase lines create their earned units once under the approved rule, with original source and expiry history.

A website registration or imported receipt alone cannot manufacture spendable rewards. The opening balance is reconciled from verified historical lots and reservations during rollout. These programs use noncash promotional points; purchased stored value and unsupported liability-based programs require separate scope.

Reserve a reward before accepting its discount

LoyaltyReservations holds eligible unexpired units against one verified purchase. The accepted offer retains the conversion, discount amount and exact line allocation. Committing that offer consumes the same claim once; it does not add a cash tender or subtract the discount from the invoice again. Pending external outcomes keep the claim held until the actual result is known.

Returns follow the original earned and spent-unit lineage. Already spent earning becomes visible clawback debt that blocks further reward spending until cleared. Expiry cannot consume a unit already committed or actively reserved. Independent adjustments retain their reason, decision and previous source history.
