The problem it solves

DTC brands on Shopify usually find out about a stockout only after the storefront shows sold out, by which point the lost sales are already gone. This agent monitors days of supply against vendor lead times every day, drafts the purchase orders that need to go out, and flags substitutions when a reorder won't land in time, so the buying team approves rather than scrambles.

Who it's for

  • Inventory managers at DTC brands with 20-500 active SKUs
  • Buying leads who own purchase orders and vendor relationships
  • DTC operators on Shopify with a 3PL or native fulfillment model
  • Ecommerce supply-chain teams replacing manual reorder spreadsheets

What it does

  1. 1

    Pull inventory and velocity daily

    Each day it reads on-hand quantity, average daily sell-through, days of supply, open POs, and backorder queues per SKU from Shopify and any connected 3PL.

  2. 2

    Detect reorder points

    It compares each SKU's days of supply against vendor lead time plus safety stock, then sorts items into reorder now, reorder soon, healthy, or overstocked.

  3. 3

    Prioritize at-risk SKUs

    Any SKU with an active backorder queue is treated as a priority regardless of the velocity math, so the most urgent gaps surface first.

  4. 4

    Calculate order quantities

    For reorder-now SKUs it computes the quantity needed to hit your target days of supply, rounded to the order increment and respecting each vendor's minimum order quantity.

  5. 5

    Draft consolidated POs

    It groups line items by vendor into draft purchase orders with unit costs and expected delivery dates, saving them to Drive or SharePoint for approval.

  6. 6

    Flag substitutions

    When a reorder can't arrive before stockout, it surfaces an in-catalog substitute SKU and a recommended action without touching your storefront.

  7. 7

    Alert on overstock

    SKUs above your overstock threshold are flagged with their velocity trend and a recommendation to pause reorder, promote, or transfer stock.

  8. 8

    Post the daily digest

    It sends a structured Slack summary of reorder-now SKUs with draft PO links, the reorder-soon watchlist, substitution flags, and open POs in transit.

Key benefits

  • See stockout risk days ahead instead of after the storefront sells out
  • Get vendor-ready purchase orders drafted automatically, not built by hand in spreadsheets
  • Order quantities that already respect MOQs, increments, and lead times
  • Keep revenue flowing with substitution options for SKUs that will gap
  • Free up cash by catching overstocked SKUs before you reorder them
  • Every recommendation logged for buying-team review and approval

Sample use cases

A hero SKU is selling 50% faster than its trailing average ahead of a promo.

The agent shortens that SKU's rolling window, recalculates days of supply, flags it as reorder now, and drafts a PO sized to the new velocity.

A bestselling item will sell out two weeks before the reorder can arrive.

It surfaces an in-stock substitute SKU with current stock on both and recommends promoting the substitute while the PO is in transit.

Six SKUs from the same vendor all hit their reorder point in one week.

The agent consolidates them into a single draft PO with quantities, unit costs, and a delivery date, saved to Drive for one-click buying-team approval.

A slow-moving SKU has 180 days of supply sitting in the warehouse.

It flags the overstock with the velocity trend and recommends pausing reorder, running a promotion, or transferring stock to a faster-moving location.

Key integrations

  • Shopify

    Source of the SKU catalog, inventory levels, and order velocity.

  • ShipBob, ShipHero, Extensiv, or Cin7

    3PL and warehouse systems for on-hand inventory records and fulfillment data.

  • NetSuite

    Vendor records covering minimum order quantities, lead times, and pricing (a vendor spreadsheet works too).

  • Google Drive or SharePoint

    Storage for draft purchase orders awaiting buying-team review.

  • Slack

    Channel for the daily replenishment digest and reorder alerts.

Stockouts and overstock are two sides of the same problem: not knowing days of supply against real vendor lead times until it is too late to act. This ecommerce inventory management agent closes that gap by turning a daily inventory pull into a ranked, vendor-ready list of what to reorder, what to watch, and what to substitute.

Because every order quantity already accounts for MOQs, order increments, and safety stock, the buying team spends its time approving purchase orders rather than rebuilding them, and the agent logs every recommendation for review before anything reaches a vendor.

Getting started

  1. Import the workspace — Bring the DTC reorder and replenishment workspace into Gamut to get started.
  2. Run agent onboarding — The agent-onboarding skill asks about your catalog, inventory source, vendor data, reorder parameters, and output preferences, then connects your accounts.
  3. Give it a first task — Ask it to run today's inventory check and show you everything that needs to be reordered.

Frequently asked questions

What does this ecommerce inventory management software agent actually do?

It monitors sell-through and inventory levels across your SKUs every day, detects which items are nearing their reorder point, and drafts consolidated purchase orders by vendor. It also flags substitutions for SKUs that will gap and posts a daily replenishment digest to Slack.

Will it place orders or submit POs without my approval?

No. The agent only drafts purchase orders and surfaces recommendations. It never submits a PO to a vendor, makes a purchasing commitment, or changes your Shopify listings, prices, or inventory without an explicit buying-team approval step.

Which systems does it work with?

It connects to Shopify for catalog and velocity, 3PLs like ShipBob, ShipHero, Extensiv, or Cin7 for warehouse inventory, NetSuite or a vendor spreadsheet for lead times and MOQs, Drive or SharePoint for draft POs, and Slack for the daily digest.

How is this different from managing reorders in a spreadsheet?

Unlike a static spreadsheet or generic inventory management software for ecommerce, the agent recalculates days of supply daily against real vendor lead times and safety stock, drafts the actual POs grouped by vendor, and adapts to velocity shifts automatically so nothing slips through the cracks.

Does it handle sudden changes in demand?

Yes. If a SKU's velocity shifts more than 50% in the past 7 days, the agent notes the change and uses a shorter rolling window for that SKU, so a promo spike or sudden slowdown is reflected in the reorder math rather than masked by an old average.

How much does it cost to run?

The template is free to import into Gamut. You only pay for usage as the agent runs and for any third-party systems you connect, such as your Shopify, 3PL, or NetSuite accounts.
