Your Aurora plant runs on 1990s PLCs and a NetSuite that finds out about scrap a day late
For Aurora manufacturers and I-88 distribution centers, custom ERP (Enterprise Resource Planning) makes sense once off-the-shelf systems force you to re-key data between aging PLCs and your order book. Expect $90,000 to $180,000 and 5 to 8 months for a tailored core that pulls live machine and inventory signals instead of waiting for a nightly batch. Below that scope, configured NetSuite or Odoo usually wins.
You bought NetSuite or SAP Business One to run the whole plant, and on paper it does. In practice the modules that matter most for an Aurora light-manufacturing operation are the ones that never quite fit: a routing built for discrete assembly when half your jobs are short-run sheet metal, a costing engine that assumes you know setup time before the press runs, and a warehouse view that's accurate at 6 a.m. and fiction by noon.
The deeper crack is the shop floor. Most of your machines predate the ERP by 20 years and speak Modbus or a serial protocol, not REST. So someone keys production counts into NetSuite by hand, and the system that's supposed to be your single source of truth is always a shift behind reality. Odoo and Microsoft Dynamics have the same blind spot, just priced differently.
The fix: erp built for Aurora, not rented
A custom ERP for an Aurora plant earns its money at one seam: the integration layer between old iron and modern order management. You build a thin core around your real routing, then a connector that reads counts and downtime straight off the PLCs through an OPC-UA or Modbus gateway, so costing, inventory, and promising all run on numbers that are minutes old, not hours. You keep the parts NetSuite does well (GL, AP) and stop paying per-seat for the parts it does badly.

How long it takes, phase by phase
Exactly what you get
A manufacturing ERP core sized to your real routing, a shop-floor gateway that turns PLC signals into live inventory and costing, a distribution module that matches your I-88 picking and 3PL rules, and clean links into whatever finance package you keep. You also get the unglamorous deliverables that decide whether it survives: a runbook for the connector, alerting when a machine feed goes silent, and a migration plan off your current system that doesn't lose two years of cost history.
How to choose a developer in Aurora
Hire for integration scars, not slide decks. The team that will succeed here has stood on a shop floor in Aurora or a similar I-88 plant and pulled data off equipment older than their interns. Ask for a reference where they connected legacy machinery to a modern order system, and ask what broke. Pair the ERP build with a hard look at your inventory management software and warehouse management system, since those three share the same live data spine and you don't want three teams owning one truth.
- Live WIP and finished-goods counts pulled from machine signals, not retyped from a clipboard at end of shift
- Job costing that uses actual measured run and setup time, so quotes on the next short-run order reflect reality
- A promising engine that knows your I-88 distribution lead times and your suppliers' real variance, not a static default
- One workflow that spans the Aurora plant and your satellite distribution sites without a nightly sync gap
- Lower seat costs by keeping finance on a packaged GL and only building the manufacturing core that doesn't fit
- You take on the maintenance NetSuite would have handled, including version upgrades and someone on call when a connector drops
- Tax, compliance, and bank feeds are genuinely cheaper to rent than build, so a full from-scratch ERP is rarely the right call
- A custom core has no ecosystem of pre-built add-ons, so every future module is a project, not a marketplace install
- First-year total cost usually exceeds a configured Odoo or NetSuite deployment, even if year three is cheaper
- !They quote a fixed price before seeing your floor; ask how they'll read counts off a 1995 PLC
- !No one on the team has touched OPC-UA, Modbus, or serial integration; ask for a specific past plant
- !They propose ripping out NetSuite's GL on day one; ask why finance can't stay packaged
- !They can't name your distribution picking strategy; ask them to model your 3PL contract terms
Teams investing in erp in Aurora usually scope it next to internal tools, shopify, inventory management, since these systems share data and budgets.

Frequently asked questions
Can custom ERP read data from our older Aurora shop-floor machines?
Yes, that's usually the whole reason to build. A gateway speaking OPC-UA, Modbus, or a serial protocol reads counts, cycle time, and downtime off existing PLCs without retrofitting the machines, then feeds your costing and inventory in near real time.
Should we replace NetSuite entirely or build around it?
Build around it in most cases. Keep NetSuite or your packaged system for GL, AP, and tax, where renting is cheaper than building, and only construct the manufacturing and distribution core that doesn't fit your operation.
How long before it's running on the floor?
Plan 5 to 8 months to first go-live for a manufacturing core with a shop-floor connector. A full replacement that also takes over finance runs 9 to 14 months and is rarely worth it for a mid-size Aurora plant.
What does a custom ERP cost for a mid-size Aurora manufacturer?
Expect $90,000 to $180,000 for a tailored manufacturing-and-distribution core with live machine integration. A full from-scratch ERP that also replaces finance starts around $200,000.
How does this connect to our inventory and warehouse systems?
They share one live data layer. The ERP reads machine and receipt signals, your inventory management software and warehouse management system draw on the same feed, so stock counts reconcile instead of drifting apart across nightly batches.
