Your NetSuite doesn't know what a die spotting press is, and Windsor mould shops feel it daily
A custom ERP (Enterprise Resource Planning) for a Windsor tool-and-die or auto-parts shop runs $70,000 to $200,000 and 4 to 8 months. The reason you're reading this is that NetSuite and Dynamics model a tidy made-to-stock factory, while your floor runs one-off moulds, die spotting, and Stellantis just-in-time releases that change weekly. A focused build wraps your CNC job tracking, USMCA paperwork, and PPAP records into one system instead of three.
You bought an off-the-shelf ERP expecting it to run the shop. Instead, your estimator still quotes a $180,000 injection mould in a spreadsheet because NetSuite has no concept of cavity counts, EDM hours, or steel grade markups, and SAP's Make-to-Order module assumes a BOM you won't finalize until the third tryout.
Then there's the border. Every skid crossing the Ambassador Bridge to a Detroit OEM needs a commercial invoice, USMCA certification, and HS codes that your generic ERP treats as a free-text note. Your shipping lead keys it twice, once in the ERP and once in the broker's portal, and a single transposed tariff line means the load sits at customs while the line in Auburn Hills waits.
Budgeting a erp build in Windsor
| Project scope | Typical cost | Timeline |
|---|---|---|
| Job-tracking + quoting layer on top of existing accounting | $70k to $110k | 4 to 5 months |
| Full ERP with CNC routing, customs and PPAP | $120k to $180k | 6 to 8 months |
| Multi-division group (tooling + greenhouse/ag) build | $160k to $200k+ | 8 to 10 months |
The case for owning your erp
A custom ERP earns its keep when your real product is engineering hours on a single die, not units off a line. It can quote from a parametric mould template, route a job through roughing, EDM, spotting and tryout as discrete operations, attach the USMCA cert to the shipment automatically, and keep the PPAP binder linked to the part. That's the difference between knowing a job is 'late' and knowing it's stuck at the spotting press waiting on a $4,000 insert.
- Quotes for moulds and dies take a day each and live entirely in spreadsheets
- You run weekly JIT releases for a Detroit OEM and reconcile schedules by hand
- Customs paperwork is double-keyed and loads have sat at the bridge over errors
- Three or more systems (quoting, scheduling, accounting) don't talk to each other
- You run make-to-stock production with stable BOMs, not one-off tooling
- Standard NetSuite or Odoo manufacturing covers your routings without heavy mods
- You have no in-house owner to maintain a custom system after launch
- Annual cost of the manual workarounds is comfortably under $40,000

Delivery, week by week
Exactly what you get
A system that treats a die as a project with operations, not a SKU. You get parametric quoting, a shop-floor job router that knows the difference between roughing and tryout, a customs module that emits USMCA certs and HS codes, and PPAP records bolted to the part. The win is one source of truth from quote to Detroit-bound skid, instead of an estimator's spreadsheet, a whiteboard, and a broker portal you reconcile at month-end. Pair it with custom CRM (Customer Relationship Management) development for your OEM relationships and business intelligence dashboards for margin-per-job visibility.
How to choose a developer in Windsor
Hire someone who can sit on your floor and tell a wire EDM from a sinker without you explaining it. Ask for a discovery sprint where they map one real mould job end to end, quote to ship. Anyone who proposes a fixed price before that doesn't understand tooling. Insist on a Windsor or cross-border reference who deals with the same customs reality you do, and make sure they'll connect to your accounting software rather than rebuilding the general ledger from scratch.
- Quote a mould or die from a parametric template in an hour instead of a day, with steel, cavitation and EDM markups built in
- Track every job at the operation level (roughing, EDM, spotting, tryout) so you know exactly where a Stellantis program sits
- Generate USMCA certs, HS codes and commercial invoices straight from the order, ready for the broker before the truck loads
- Keep PPAP, IATF 16949 and capability records linked to the part number and routing, audit-ready in minutes
- Tie greenhouse or ag-equipment divisions into the same costing engine if your group runs more than tooling
- A real ERP build is the most expensive system on this list and the slowest to pay back; under $40k of annual waste rarely justifies it
- You become the maintainer of accounting and tax logic that QuickBooks or NetSuite would have patched for free every year
- Migrating ten years of job history and steel inventory off your old system is its own painful sub-project
- If your shop's processes are genuinely standard, you're paying custom prices for what Odoo manufacturing could do at a fraction
- !They've never heard of PPAP or IATF 16949; ask them to walk you through a quality build they shipped
- !They quote a fixed price before seeing your job router; ask how they handle one-off tooling vs stock production
- !No plan for USMCA cert generation; ask exactly how shipments will hit the broker portal
- !They want to force your mould quoting into a standard sales-order screen; ask to see their parametric quoting demo
- !They can't name a single ERP migration they've finished; ask for two references with old-data cutover stories
Most Windsor teams pricing erp end up comparing notes on internal tools, shopify, inventory management too; the systems share one data spine.

Frequently asked questions
Can't Odoo or NetSuite manufacturing handle a tool-and-die shop?
They handle repeat production well. A mould shop's product is engineering hours on a one-off die, which their make-to-order modules model awkwardly. You can mod them, but past a certain point the mod cost approaches a focused custom build that fits your floor exactly.
How do you handle USMCA paperwork for Detroit shipments?
A custom ERP generates the commercial invoice, HS codes and USMCA certificate of origin from the order data, so your shipping lead exports it to the broker portal instead of retyping it. That removes the double entry that causes loads to sit at the bridge.
What does an ERP build cost for a Windsor shop our size?
Expect $70k to $110k for a job-tracking and quoting layer on top of your existing accounting, and $120k to $180k for a full ERP with CNC routing, customs and PPAP. Multi-division groups run higher.
Will it integrate with our accounting software?
Yes, and it should. Most Windsor shops keep QuickBooks or Sage for the books and build the ERP to own job costing, scheduling and customs, syncing financial totals across. Rebuilding accounting from scratch is wasted money.
How long before we're off spreadsheets?
A routing and quoting layer ships in 4 to 5 months; a full ERP in 6 to 8. Most shops run the new quoting and job tracking in parallel with the old method for a few weeks before cutting over.
