Peptide Inventory & Fulfillment Software

One stock record, reserved on the order

The fragile version of inventory has one number on the storefront and another in the warehouse. A scheduled sync tries to reconcile them every few minutes. That works until two orders arrive inside the interval, a manual order is entered, or a cancelled payment releases stock in only one place.

The reliable version keeps one sellable stock record and changes it in the same server-side transaction that records the order. The storefront can still cache pages for speed, but availability is checked against the source of truth before the order is accepted.

This matters even more for kits and bundles. A kit consuming ten units and a single-unit order must reserve against the same underlying product, or the catalog will oversell while every individual screen appears internally consistent.

From paid order to customer tracking

The goal is not another dashboard. It is a controlled sequence where each state gives the next person exactly the work they can perform.

1. 1

   Confirm payment and reserve stock

   The order becomes actionable only when its payment path says it is ready, and the stock reservation is part of that order record.

2. 2

   Queue the oldest ready work

   The fulfillment team sees paid orders in waiting-time order, with holds and exceptions separated instead of mixed into the pack queue.

3. 3

   Pick and verify

   Items, quantities and associated lot data are confirmed before the package advances. A mismatch stops the order in a visible state.

4. 4

   Buy the label from the order

   The selected carrier service, package details, cost and tracking number are written back without retyping an address into another tool.

5. 5

   Notify and monitor

   The customer receives tracking from the same event that marks the shipment, while the team keeps delivery status attached to the order.

Supplier inventory is an input, not your source of truth

Dropship and supplier-fed catalogs add another number: what a partner says is available. That number is useful, but it is not identical to what your storefront can safely promise. Feed delays, your own open orders and products assembled from multiple units all sit between the two.

We ingest supplier availability on a schedule, record when it was last observed, and apply the company's own sellable-stock rules before exposing it. When a feed goes stale, the system can hold or reduce availability instead of continuing to sell from an old answer.

That distinction keeps an integration outage from quietly becoming a customer-service problem hours later.
