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
| Field | Description |
|---|---|
| Supplier | Who you’re ordering from |
| Destination Warehouse | Where items will be received |
| Line Items | SKUs and quantities to order |
| Unit Cost | Price per unit |
| Lead Time | Expected 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.Steps in a Purchase Order
| Step Type | Inventory States | What Happens |
|---|---|---|
| Purchase | In Process → Completed Purchase | Tracks supplier order progress. No warehouse inventory changes until shipment. When completed, inventory is added to sellable at the supplier’s linked warehouse. |
| Shipment | In Transit → Completed Shipment | Created 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
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
| Field | Description |
|---|---|
| Source Warehouse | Where items are coming from |
| Destination Warehouse | Where items are going |
| Line Items | SKUs and quantities to transfer |
| Lead Time | Transit 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.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 Type | Inventory States | What Happens |
|---|---|---|
| Shipment | In Transit → Completed Shipment | The 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)
- Added to “Awaiting In-Transit” when submitted
- Moved to sellable when shipment is completed
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
| Field | Description |
|---|---|
| Produced SKU | What you’re making |
| Components | Raw materials/parts needed |
| Quantity | How many to produce |
| Warehouse | Where production occurs |
| BOM | Bill 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.Steps in a Production Order
| Step Type | Inventory States | What Happens |
|---|---|---|
| Production | In Production → Completed Production | Tracks manufacturing progress. Components are committed (subtracted from sellable) and consumed during production. Finished goods are added to sellable at the source warehouse on completion. |
| State | Description |
|---|---|
| Committed | Components reserved—subtracted from sellable at the supplier warehouse |
| Consumed | Components actually used in production |
| Backordered | Components 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
- Added to sellable at the source warehouse when production completes
Bill of Materials (BOM)
Production uses BOM to determine components:Comparing Transaction Types
| Aspect | Purchase Order | Transfer Order | Production Order |
|---|---|---|---|
| External/Internal | External (supplier) | Internal | Internal |
| Cost Tracking | Yes (supplier cost) | No (internal) | Yes (component cost) |
| Source | Supplier (resolved to warehouse) | Warehouse | Supplier |
| Destination | Warehouse | Warehouse | Warehouse |
| Step Types | Purchase + Shipment | Shipment only | Production |
| Lead Time | Supplier + shipping | Transit time | Production time |
| Auto Shipping Plan | No (created manually) | Yes (on submission) | No (created manually) |
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

Purchase Order Specifics
Supplier Selection
Supplier Selection
When creating a PO:
- Choose from configured suppliers
- System shows supplier’s lead time and costs
- Can have multiple suppliers for same SKU
Cost Information
Cost Information
Purchase orders include:

Receiving
Receiving
When PO arrives:
- Can receive partial quantities
- Log discrepancies
- Update actual costs if different
Transfer Order Specifics
Availability Check
Availability Check
When creating a transfer:
- System verifies source has sufficient sellable inventory
- Shows available quantities at source
- Blocks submission if insufficient stock
Lead Time
Lead Time
Transit time depends on:
- Configured warehouse lead times
- Distance between locations
- Shipping method
Automatic Shipping Plan
Automatic Shipping Plan
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
BOM Verification
BOM Verification
Before production:
- Verify BOM is configured
- Check component availability
- Reserve components
Yield Tracking
