Alternatives
One system instead of five.
Yes — one system can run quoting, production scheduling, the shop floor, purchasing, suppliers, CRM, email and a real general ledger. KG Ai ERP does, on one database and one part number, with no handoff between them.
What follows is how that differs from the tools a machine shop or fab shop is usually comparing, and what every one of them leaves on the table.
The four things people compare
Each category solves a different quarter of the job.
Every tool below is good at what it was built for. None of them was built to run the whole lifecycle on one record.
Quote-only tools
AI estimating that reads a drawing or a CAD model and returns a price. Fast, and genuinely good at the quote.
Where it stops: the quote goes out and the trail ends. Paperless Parts states in its own documentation that it does not generate or suggest shop-specific pricing, and the history it searches is the geometry of parts you have already quoted — not the hours those jobs actually took.
Shop ERPs
JobBOSS², E2, ProShop, MIE Trak. Built for job shops, and they do capture actuals — setup, run, material, scrap — properly.
Where it stops: the actuals land in a report, not in the next estimate. Re-quoting a part means copying an old quote or looking up a cost in a library. A person has to notice, remember and retype.
General business ERPs
Odoo, NetSuite, Dynamics 365. Broad, mature, and built to serve every industry at once.
Where it stops: job-shop estimating is not in the core. Odoo's own app store sells a third-party module to add it — machine burden rates, outside processes, quantity breaks — pitched as a way to do estimates "without spreadsheets." That tells you where estimating lives without it.
Inventory and commerce platforms
Katana and the like. Strong at stock, purchase orders and multi-channel fulfilment.
Where it stops: it is built for a different manufacturer. Katana describes itself as "built for product businesses selling across multiple channels and locations." A shop quoting a one-off housing from a print is not selling a SKU.
The gap none of them close
Every one of them quotes. None of them corrects the quote.
An AI agent that drafts a quote from a drawing is now ordinary. Four of the platforms above will do it.
What none of them does is take what the job actually cost — the setup that ran long, the material you burned, the margin the ledger finally recorded — and put it on the next estimate for that part without anyone asking.
It is the reason KG Ai ERP is an ERP first and an estimator second — and the reason Si-Q gets better on your floor every week. How Si-Q works
Straight answers
The questions people actually ask.
Can one system really replace CRM, email, quoting, accounting and production scheduling?
Yes. KG Ai ERP runs all five on one database: email and RFQs land on the job, the quote becomes the job, the floor clocks against it, and the invoice posts to a real general ledger. There is no integration layer between them because there are no separate systems to integrate.
What is an AI-native ERP, and how is it different from an ERP with AI added?
An ERP with AI bolted on runs its old workflow and calls a model at one step. AI-native means the data model was built so the AI can see the whole job — print, routing, clock, crib, invoice and ledger — and act on all of it.
Does it quote from a CAD model or only from a 2D print?
Both. A 3D CAD model is measured for envelope and features; a 2D PDF is read for material, tolerances and finish off the title block and notes. Either way every figure on the quote carries its source.
How is this different from Paperless Parts or DigiFabster?
Those price the part. This prices the part and then runs the job, so what the job actually cost comes back and corrects the next estimate. A quote-only tool never sees the floor, so it has nothing to learn from.
How is this different from JobBOSS², E2 or ProShop?
Those capture actuals properly and then stop. The numbers land in a report, and re-quoting means copying an old quote or looking up a cost. Here the actuals feed the next estimate without anyone retyping them.
Do we have to change how our shop works to use it?
No. You describe your shop and it configures to that — your machines, your rates, your numbering, your routings. You approve every setting before it is stored.
Is it built for machine shops, sheet metal fab, or both?
Both, and for job shops running a mix. It was built inside a working precision CNC shop, which is why the scheduling is machine-and-capacity based rather than generic project tasks.
