Safety Stock

Recomputes safety stock per item from demand and lead-time variability against your service target, and proposes each change.

About

Safety stock exists to absorb variation, yet it is usually set from an average and left alone. Safety Stock reads daily demand per item and location, the lead time each receipt actually took against its purchase order date, the service target you assign per item class, and the buffer currently on the item record.

It measures how much demand and lead time vary, sizes a buffer that meets the service target at that variation, and compares it with the current value. Where the two have drifted apart by more than your threshold, a change is proposed with both figures shown. A planner approves, and the item record is updated only then.

This is a reference listing. It documents what Fibric would read from Safety Stock and what it could propose, based on the vendor's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • Safety Stock Level on the NetSuite item record, as a quantity or as days, and Safety Stock Quantity on the Business Central item card
  • safety_stock_level per variant and location on the Katana inventory object
  • Daily units sold per SKU and location from Shopify or BigCommerce orders, or a demand table in PostgreSQL or BigQuery
  • Purchase order dates and item receipt dates, to measure how lead time varies per vendor and item
  • A service target per item class, entered by the planner and stored with the item
  • Open stockouts and backorders, which show where the current buffer has already failed

Proposed actions

  • Target capability: propose a new Safety Stock Level on a NetSuite item record, as a quantity or as days
  • Target capability: propose a new Safety Stock Quantity on a Business Central item card or stockkeeping unit
  • Target capability: propose a new safety_stock_level for a Katana variant at a location
  • Target capability: propose lowering a buffer where measured variation has fallen, with the units and value it frees

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Right-size buffers after a vendor's lead time turns erratic

    Receipt dates against NetSuite purchase orders show a vendor's lead time spreading. A larger Safety Stock Level is proposed for the affected items, with Shopify demand and the measured spread shown.

    With NetSuite, Shopify

  • Release cash from buffers that are too large

    Demand from a BigQuery table has settled for a category. Lower Safety Stock Quantity values are proposed in Business Central, with the units and value each change frees.

    With BigQuery, Microsoft Dynamics 365 Business Central

  • Keep Katana buffers matched to storefront demand

    Daily units from BigCommerce orders and receipts on Katana purchase orders size a safety_stock_level per variant and location. The planner approves each before it is written.

Requirements

  • An item record that stores a safety stock field: NetSuite, Business Central, or Katana
  • Daily demand per SKU and location for the window you set, from a storefront or a table
  • Purchase orders and receipts for the same items, so lead-time spread is measured rather than assumed
  • A service target per item class and a drift threshold, both set by the planner
Authentication
ERP or inventory credentials with item read and update rights (a NetSuite REST integration, a Business Central OAuth app, or a Katana API key), plus read-only access to orders or the demand table.

Limits

  • Items with too few receipts to measure lead-time spread keep the buffer they have. The card says why.
  • NetSuite accepts safety stock only as a quantity for demand planning items. Days are proposed only where the record allows them.
  • Service targets are yours. The listing does not pick a target from margin or cost.
  • The buffer covers variation in demand and lead time. It does not size for a promotion you have not entered.

Questions and answers

How is safety stock sized?
From the spread of daily demand and the spread of lead time over the window, combined at the service target you set per item class. The card shows the two spreads, the target, and the resulting units, next to the current value.
When is a change proposed?
Only when the computed buffer and the current one differ by more than the drift threshold you set, in units or in value. Items inside the threshold are listed as reviewed with no proposal.
What is written, and what record is left?
Only the safety stock field on the item record, after a planner approves. The record keeps the previous value, the new one, the spreads and service target used, who approved, and when. The previous value can be proposed back.
