Transaction Types

Tether supports three main transaction types, each serving a different purpose in your supply chain.

Purchase Orders

Purchase orders are orders placed with external suppliers.

When to Use

  • Buying products from suppliers
  • Replenishing inventory from external sources
  • Ordering raw materials for production

Key Information

FieldDescription
SupplierWho you’re ordering from
Destination WarehouseWhere items will be received
Line ItemsSKUs and quantities to order
Unit CostPrice per unit
Lead TimeExpected delivery time

Purchase Order Workflow

When a purchase order is submitted, Tether creates a Purchase step to track the supplier fulfillment, followed by a Shipment step when a Shipping Plan is created to move goods to your warehouse.
Draft → In Progress (Purchase Step: In Process → Completed Purchase)
                     → Shipment Step: In Transit → Completed Shipment
     → Completed

Steps in a Purchase Order

Step TypeInventory StatesWhat Happens
PurchaseIn Process → Completed PurchaseTracks supplier order progress. No warehouse inventory changes until shipment. When completed, inventory is added to sellable at the supplier’s linked warehouse.
ShipmentIn Transit → Completed ShipmentCreated when a Shipping Plan artifact is submitted. Subtracts inventory from source, adds to “Awaiting In-Transit” at destination. On completion, moves to sellable at destination.

Cost Tracking

Purchase orders track costs through artifacts:
  • Unit costs per SKU (on line items)
  • Shipping and freight costs (artifact-level cost items)
  • Duties, tariffs, and taxes (artifact-level cost items)
  • Total order value
The Analysis tab shows planned vs. reported cost variance once the transaction is in progress.

Transfer Orders

Transfer orders move inventory between your warehouses.

When to Use

  • Rebalancing inventory across locations
  • Sending stock to fulfill demand elsewhere
  • Consolidating inventory
  • Moving to a different storage location

Key Information

FieldDescription
Source WarehouseWhere items are coming from
Destination WarehouseWhere items are going
Line ItemsSKUs and quantities to transfer
Lead TimeTransit time between locations

Transfer Order Workflow

When a transfer order is submitted, Tether automatically creates a Shipping Plan artifact and a Shipment step. All inventory immediately enters the “In Transit” state—there are no intermediate picking steps.
Draft → Submitted (auto-creates Shipping Plan + Shipment Step)
     → In Progress (Shipment Step: In Transit → Completed Shipment)
     → Completed
Unlike purchase orders, transfer orders create a Shipping Plan automatically on submission. The full quantity immediately enters “In Transit” status.

Steps in a Transfer Order

Step TypeInventory StatesWhat Happens
ShipmentIn Transit → Completed ShipmentThe only step type for transfers. On creation, subtracts inventory from source warehouse sellable and adds to “Awaiting In-Transit” at destination. On completion, moves to sellable at destination.

Inventory Impact

Transfer orders affect inventory at both locations immediately on submission: Source Warehouse:
  • Sellable inventory subtracted when submitted (enters In Transit)
Destination Warehouse:
  • Added to “Awaiting In-Transit” when submitted
  • Moved to sellable when shipment is completed
If the source warehouse does not have sufficient sellable inventory at submission time, the submission is blocked with an error.

Production Orders

Production orders are for internal manufacturing.

When to Use

  • Manufacturing finished goods from components
  • Assembling kits or bundles
  • Converting raw materials
  • Any internal production process

Key Information

FieldDescription
Produced SKUWhat you’re making
ComponentsRaw materials/parts needed
QuantityHow many to produce
WarehouseWhere production occurs
BOMBill of Materials defining inputs

Production Order Workflow

When a production order is submitted, Tether creates a Production step that tracks both the finished goods being produced and the components being consumed.
Draft → In Progress (Production Step: In Production → Completed Production)
     → Completed

Steps in a Production Order

Step TypeInventory StatesWhat Happens
ProductionIn Production → Completed ProductionTracks manufacturing progress. Components are committed (subtracted from sellable) and consumed during production. Finished goods are added to sellable at the source warehouse on completion.
Component inventory states (tracked within the production step):
StateDescription
CommittedComponents reserved—subtracted from sellable at the supplier warehouse
ConsumedComponents actually used in production
BackorderedComponents that could not be committed due to insufficient inventory

Inventory Impact

Production orders affect multiple SKUs: Components (at supplier warehouse):
  • Subtracted from sellable and moved to Committed when production starts
  • Moved from Committed to Consumed during production
  • Marked as Backordered if insufficient inventory is available
Finished Goods (produced):
  • Added to sellable at the source warehouse when production completes

Bill of Materials (BOM)

Production uses BOM to determine components:
Finished Good: T-Shirt Bundle (3-pack)
├── Blue T-Shirt M × 1
├── Blue T-Shirt L × 1
├── Blue T-Shirt XL × 1
└── Poly Bag × 1 (Component)

Choosing the Right Type

Use Purchase Order When:

  • Inventory comes from outside your organization
  • You’re paying an external supplier
  • Items don’t exist in your inventory yet

Use Transfer Order When:

  • Inventory already exists in your warehouses
  • You need to move stock between locations
  • No external purchase is needed

Use Production Order When:

  • You manufacture or assemble products
  • Finished goods are made from components
  • You need to track production costs

Transaction Type Details

Purchase Order Specifics

When creating a PO:
  • Choose from configured suppliers
  • System shows supplier’s lead time and costs
  • Can have multiple suppliers for same SKU
Purchase orders include:
  • Unit cost per SKU
  • Shipping estimates
  • Currency handling
  • Volume discounts
When PO arrives:
  • Can receive partial quantities
  • Log discrepancies
  • Update actual costs if different

Transfer Order Specifics

When creating a transfer:
  • System verifies source has sufficient sellable inventory
  • Shows available quantities at source
  • Blocks submission if insufficient stock
Transit time depends on:
  • Configured warehouse lead times
  • Distance between locations
  • Shipping method
Unlike purchase orders:
  • A Shipping Plan is created automatically on submission
  • All inventory immediately enters “In Transit”
  • No additional shipments can be created since everything is already shipped

Production Order Specifics

Before production:
  • Verify BOM is configured
  • Check component availability
  • Reserve components
During production:
  • Track actual vs. planned output
  • Log waste or scrap
  • Calculate yield rates
Production costing includes:
  • Component costs
  • Labor (if tracked)
  • Overhead allocation
