Inventory optimization software for distributors: SKU-level forecasts, stock targets and purchasing recommendations for the next supplier order.

Prioritize the next supplier order

A stock balance tells you what is on hand. It does not tell you if the next purchase should go to a fast seller, a backordered item or a supplier with a long lead time. Convexity combines inventory and demand planning. Purchasing teams use it to review replenishment priorities.

Both excess stock and stockouts cost money

Excess inventory ties up cash and can lead to storage costs or markdowns. Stockouts can mean missed sales. Inventory optimization helps your team balance these trade-offs. It does not solve every shortage by buying more of everything.

Inputs for a replenishment plan

  • Sales history and demand forecasts for each SKU.

  • On-hand, available, and reserved stock, plus incoming purchases where the source provides them.

  • Supplier lead times, minimum order quantities and purchasing units.

  • Min/max levels, reorder points, safety-stock policies and the service priorities agreed for your business.

  • Budget or supplier limits to assess when you define the optimization model.

Definitions matter. On-hand stock is not always available to sell. An open purchase order is not received inventory. Map these fields and your customer-specific priority rules before you act on a recommendation.

From inventory data to a buy recommendation

Step 1 —

Check stock and incoming purchases

Connect the relevant inventory, sales and supplier records. Check stock definitions, units, open orders and the most recent successful refresh.

Step 2 —

Review stock targets and suggested buys

Use forecast demand and configured purchasing rules to review suggested stock levels and order quantities. Check the items that need attention before you place an order.

Step 3 —

Create drafts automatically, then review the buy

Enable automatic draft creation to prepare purchase orders from recommendations. Your buyer can review quantities, supplier details and exceptions before approval. Draft creation does not itself send a supplier order or write it into another ERP.

Example: a distributor prioritizing a vendor order

A low stock balance does not always mean you need another purchase. Check if an existing order will arrive in time. Then compare the remaining shortage with supplier minimums and pack sizes. Use this to adjust the recommended buy.

Check the recommendation before you order

  • Check if incoming stock will arrive before the expected shortage.

  • Compare the suggested quantity with vendor minimums and purchasing pack sizes.

  • Find the demand, lead-time or stock assumption behind an unusually large buy.

  • Record the buyer’s decision and confirm how the approved order enters the purchasing workflow.

What your team gets

  • Item-level stock targets and purchasing recommendations.

  • Sales and inventory context for reviewing suggested quantities.

  • A purchasing workspace and Ask Convexity to investigate the underlying data.

  • Draft purchase orders your buyer can review and adjust.

Begin with recommendations your buyers can check. Treat ERP writeback and unattended purchasing as separate decisions. Connecting your data does not turn them on automatically.

FAQ

Frequently asked questions

Inventory management records stock and movements. Inventory optimization decides how much stock to hold and when to replenish, using demand, supply and buying constraints. Convexity connects planning with the operational records used in purchasing.

An alongside-ERP setup is possible, subject to access and field coverage. Confirm your ERP edition, API or export options, refresh schedule and writeback needs. A read connection does not mean support for every ERP action.

These are inputs to the purchasing workflow. Confirm how your lead times, minimum order quantities, units and vendor rules appear in the data. Also confirm the agreed model supports them.

Only where that action is included and validated in your implementation. Review the proposed order and agree permissions and approval steps. Some integrations support data import before purchase-order writeback is ready.
