Wholesale distributors: inventory manager using Laravel

Summary

A inventory manager blueprint for wholesale distributors built with Laravel 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: 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; the catalog shown publicly carries list prices only. Technical basis verified on Laravel: 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).

Infrastructure requirements

• Compute: verified (Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.)
• Postgres: verified (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: verified (Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.)

Prerequisites

• A Laravel project (composer install --no-dev from composer.lock, then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 template)
• A PostgreSQL driver reading DATABASE_URL (auto-provisioned when omitted)
• Bucket credentials from ample bucket create passed as encrypted S3_* environment variables
• A review of which wholesale distributors data classes may be handled at all; this blueprint models public information only

Exact tested configuration

• template: php-8.5
• runtime: php
• size: s-1vcpu-1gb
• install: composer install --no-dev --prefer-dist --no-interaction --no-progress --optimize-autoloader
• start: frankenphp php-server --listen :$PORT --root public

Steps

1. 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 (account pricing tiers, credit terms, delivery addresses) out of this schema.

2. Workflow step 1. Model SKUs and stock movements; derive stock from movements

3. Workflow step 2. Apply movements transactionally with an optimistic version check on the SKU

4. Workflow step 3. Record an event per movement for history

5. Workflow step 4. Deploy and verify history and rejected stale updates

6. Deploy. Run the synchronous deploy once and read the result. Re-running with no change is a no-op.

   ample deploy . --name <app-name> --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...
   

7. Verify. Run the pattern self-test(s) from the example (/p/transactional-workflows) and your own acceptance checks for the wholesale distributors workflow.

Tested examples

• Laravel pattern fixture (tests/deploy-canaries/laravel-patterns): Verified transactional workflows basis for this blueprint.

Success checks

• app responds on its public URL (/ on the live URL, expect ample canary laravel patterns)
• transactional-workflows self-test from the example (/p/transactional-workflows on the live URL, expect see the pattern fixture checks)

Limitations

• The technical basis (transactional workflows on Laravel) was verified with the pattern fixture; the wholesale distributors schema and workflow are an original design for this blueprint and were not executed as a separate application.
• No health, financial, privacy or other compliance claim is made. Account-specific pricing and credit terms are confidential; the catalog shown publicly carries list prices only.
• Public content and synthetic examples only until actual data-handling requirements have been reviewed.
• Verified on the php-8.5 template at s-1vcpu-1gb; region, request-duration limits and other sizes are unknown or unverified.
• Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified.
• PutObject and GetObject with path-style addressing are verified; other S3 operations and CDN cache rules are not.

Cost estimate

Estimated 10.00 USD per month (size prices from pricing.toml at build revision a1b8c38919e59cd035ebabaced73cf84ece24371).

• app server x1 s-1vcpu-1gb: 5.00 USD
• managed PostgreSQL database x1 s-1vcpu-1gb: 5.00 USD

Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.

Verification evidence

The blueprint's Wholesale distributors schema and workflow below build on that verified basis and were not separately executed. (expires 2027-03-19T20:36:21Z)
