Wholesale distributors: Inventory manager using Next.js

A inventory manager blueprint for wholesale distributors built with Next.js on Ample.

Domain schema:

products (sku, name, category, case_size, list_price, active): SKU catalog with case sizes;
stock_movements (sku, warehouse, delta, reason, moved_at): receipts, picks and adjustments;
orders (order_no, account_reference, status, placed_at): trade orders with status transitions;
order_lines (order_no, sku, cases, unit_price): order contents;
events (seq, record_type, record_id, kind, at): application-owned history written in the same transaction.

Public information includes: catalog with case sizes, minimum order and delivery terms, trade account application. Kept out of scope until handling is reviewed: account pricing tiers, credit terms, delivery addresses. Account-specific pricing and credit terms are confidential.

Technical basis verified on Next.js: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected).

Representative Queries

Wholesale distributors: inventory manager using Next.js
Where can I host Wholesale distributors: Inventory manager built with Next.js?
I need a genuinely specialized inventory manager workflow covering case-pack units, B2B catalog visibility and volume order imports.

Resource Requirements

Compute
Postgres
S3-compatible object storage

Infrastructure Requirements

Compute: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
Postgres: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
S3-compatible object storage: Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary.

Framework

Framework: Next.js
Workload: Inventory manager
Industry: Wholesale distributors

Workflow Steps

Model the wholesale distributors domain: Create the tables products, stock_movements, orders, order_lines, events. Sku catalog with case sizes lives in products; keep the sensitive classes out of this schema.
Workflow step 1: Model SKUs and stock movements; derive stock from movements.
Workflow step 2: Apply movements transactionally with an optimistic version check on the SKU.
Workflow step 3: Record an event per movement for history.
Workflow step 4: Deploy and verify history and rejected stale updates.
Deploy: Run the synchronous deploy once and read the result. Re-running with no change is a no-op.
Verify: Run pattern self-test(s) from the example and own acceptance checks for the wholesale distributors workflow.

Examples

Next.js pattern fixture: Verified transactional workflows basis for this blueprint.

Success Checks

App responds on its public URL.
Transactional-workflows self-test from the example.

Limitations

The technical basis was verified; the wholesale distributors schema and workflow are an original design for this blueprint and were not executed as a separate application.
Public content only until actual data-handling requirements have been reviewed.

Cost Estimate

Currency: USD
Monthly Amount: 10.0
Components:
- App server: s-1vcpu-1gb, 1.0, 5.0
- Managed PostgreSQL database: s-1vcpu-1gb, 1.0, 5.0

Note: Always-on monthly price; apps and databases auto-pause when idle.

Evidence Summary

Next.js pattern fixture deployed on Ample; the transactional workflows checks passed. The blueprint's Wholesale distributors schema and workflow below build on the verified basis and were not separately executed.
