DEV3 Jigworth – Manufacturing ERP Laravel Script with BOMs, MRP, Work Orders and Lot Traceability

Jigworth is a manufacturing ERP for one manufacturer with one or more plants, built by DEV3 Technologies on Laravel 12 and Filament 4. Engineers keep multi-level bills of materials and routings, planners run MRP and release work orders, operators report on a tablet terminal at the work centre, and the owner sees stock, lots, quality holds and costs against standard.

What it does

• Bills of materials that can be trusted. Multi-level BOMs with versions and effectivity dates, scrap and yield, unit conversions and phantom kits. A loop is refused on save with the path that closes it. A tree view, where-used and side-by-side version compare are built in.
• Routings and work centres. Operations with setup and run times, work-centre calendars and holidays, and a load view that shows a work centre over capacity weeks ahead.
• MRP with pegging. A deterministic net-requirements run over sales orders, forecasts, open work orders and purchase orders, safety stock and four lot-sizing rules. Every planned order shows what it is for. Exceptions (past due, expedite, defer, cancel), a firm-and-release list and a weekly item-by-bucket grid. Tested to about 5,000 items by 26 weekly buckets.
• Work orders. Release with snapshots of the BOM and routing, issue and return material, backflush, report good and scrap quantities, finish into lots or serials, and close with the variances calculated.
• Shop-floor terminal. A tablet-first page at /floor: pair a device with a code, pick an operator, enter a PIN, see the dispatch list for the work centre, start and pause operations, report with a keypad, scan or type lots, print Code 128 labels. It locks itself after inactivity.
• Lots and serials. Receive, make and ship with FEFO or FIFO picking, lot holds, and a genealogy view from a customer's serial number back to the supplier lot.
• Quality. Inspection plans, inspections that hold a lot until someone decides, and non-conformance reports.
• Purchasing and sales. Suppliers with price breaks, receiving with tolerances, make-to-stock and make-to-order sales orders, shipments and invoices per shipment.
• Costing and variances. Standard cost roll-up, and variances split into material price, material usage, scrap and labour efficiency that add up exactly to actual minus standard.
• Reports, API and webhooks. Nine reports with CSV export, a scoped REST API with OpenAPI, signed webhooks, API keys and plant-by-plant access.

Quality checks

The release passed seven gates on the final code: Larastan level 6 with 0 errors, PEST, a build inside the page budget, migrations and the demo seed on MySQL 8 and SQLite, a headless smoke test that crawls the panel, drives the terminal and runs the MySQL race groups (two operators issuing the last lot, two MRP runs at once, finish against close, parallel shipments of one serial, parallel finishes and returns, a BOM loop attempt and PIN guessing), the installer driven from the zip, and a secret scan. The home page scores LH on mobile.

What you should know before buying

• One manufacturer, one or more plants. Discrete manufacturing: assemblies, fabricated parts, light assembly, furniture, electronics. It is not multi-company and not a process or batch-recipe system.
• MRP is deterministic net requirements with lead times and lot sizing. There is no finite-capacity scheduling optimiser and no AI forecasting: forecasts are manual or a moving average. The load view shows capacity problems; it does not solve them.
• Not accounting software. Cost and inventory values export as CSV and journal files for your accounting system.
• No CAD or PLM integration and no machine connectivity (OPC-UA, MQTT). Operators report on the terminal.
• Quantities carry six decimals and money is stored in minor units. Barcode scanning uses the browser's detector where available, with manual entry always possible.
• Web only. The terminal and the panel are responsive for tablets, and there are no native apps. A cron entry every minute is required. Node.js is not needed (assets are prebuilt).

Included

Source code, the web installer, a buyer guide with the API contract and the race notes, demo data for a fictional furniture maker with two plants, about 1,400 items and two years of history, and six months of support.
