01Keep it in-house.Hire an engineer, or free up one you already have, and let them own the function permanently. This wins when the work is not a project but a standing capability: the models need retuning as the product line changes, the workflow keeps evolving, and someone has to own governance and adoption for years rather than weeks. It also wins on control, because nothing leaves the building. What it costs, REPORTED: machine learning engineer base salary of $128,000 to $186,000 with total compensation averaging around $212,000 (interviewkickstart.com), $190,000 to $230,000 a year fully loaded at mid level once benefits, overhead, tooling and compute are counted, rising to a reported $323,300 fully loaded at six to ten years of experience, plus a one-time cost-per-hire of $22,000 to $45,000 at mid to senior level against a 60 to 90 day time-to-fill (stealthagents.com). Where it loses: it is a recurring annual cost that begins before the first production workflow exists, and one person is a single point of failure on a system the plant will come to depend on. A hire and a commission are not really substitutes; the commission ships the first system while the hire builds the second.Recurring salaryPermanent capability
02Big Four and MBB consulting.Deloitte, PwC, EY, KPMG on one side, McKinsey, BCG and Bain on the other. This genuinely wins when the decision is enterprise-wide, when several business units have to be aligned before anything can be built, and when the organisation needs an outside name attached to the recommendation for it to survive internal politics. It also wins when the scope legitimately spans corporate strategy rather than one plant workflow. What it costs, REPORTED: $400 to $800 an hour for Big Four and $500 to $1,000 or more for MBB (aidolsgroup.com); a second aggregator puts Big Four lower, at $300 to $600 an hour, which is a useful reminder that none of these figures come from the firms they describe (groovyweb.co). On a project basis the first of those sources reports strategy assessments at $25,000 to $75,000, proofs of concept at $50,000 to $250,000, single use-case deployments at $100,000 to $500,000 and enterprise rebuilds from $500,000 upward (aidolsgroup.com), and the second reports Big Four project costs spanning $20,000 to $2M and above (groovyweb.co). Where it loses: the assessment is not the expensive part, and it was never meant to be. It is priced to be affordable and the programme it recommends is priced on a different scale, so the number that decides this for you sits on the far side of the recommendation rather than on the proposal in front of you. At $400 to $1,000 an hour the scoping alone becomes a five-figure line item before anything is built, and what you hold at the end of it is a recommendation rather than a running system. Ask who specifically will be doing the work, by name and seniority, and get it into the statement of work rather than the pitch.Enterprise motionAssessment first
03ERP vendor professional services.Epicor, Infor, SAP and their certified implementation partners. This is the option manufacturers most often forget they are already half-paying for. It wins outright when the AI capability you need lives entirely inside functionality your ERP already ships. Epicor ships Prism, an agentic layer with role-based agents embedded across Kinetic, and Infor ships the Coleman AI suite (REPORTED, erpresearch.com and melonleaf.com). If the thing you want is one of those, a vendor-native implementation carries no cross-system integration risk and the licensing may already be in your contract. What it costs: no public hourly rate card exists for any of the three vendors' AI implementation work, and we are not going to invent one (GAP). For scale only, base ERP licensing for Epicor and Infor is reported to start around $80 per user per month, which is the platform, not the AI layer and not the services (REPORTED, erpresearch.com). Where it loses: the moment the need spans a system the ERP does not touch, such as a CRM, a separate quality management system or a bespoke part catalogue, you are back to an integration problem the ERP vendor has no commercial reason to solve.Vendor-nativeZero integration risk
04Industrial systems integrator.The OT and automation integrators, not the software consultancies. This wins when the AI you actually need is attached to physical equipment: machine vision on a line, robotic sorting, anything that reaches down to the PLC and SCADA layer. That is a different discipline with different safety obligations and different insurance, and a software firm should tell you plainly that it is not the right hands for it. What it costs, REPORTED: total installed cost typically lands at 1.3x to 2.0x the equipment price once installation, integration, training and floor modification are counted, which means the quote on the machine itself is somewhere between half and roughly three quarters of what the line actually costs you (amdmachines.com). No day-rate figure for integrator labour was located and none is invented here (GAP). For scale, the industrial automation SI market is reported at $43.65B in 2025 rising to $45.51B in 2026, with the top 75 firms reporting $4.67B in combined integration revenue (REPORTED, researchandmarkets.com via Plant Engineering). Where it loses: none of the seven functions on this page except parts of data analysis touch the control layer. For support, reporting, compliance monitoring and content, this is the wrong trade entirely.OT and controlsPlant floor only
05Staffing, contract engineers and independent consultants.Wins when you already know exactly what to build, have someone internally who can direct the work, and need hands rather than judgment. It is also the cheapest way to test whether a small piece of work is feasible before committing to a larger engagement. What it costs, REPORTED: freelance AI consultants at $75 to $150 an hour and boutique agencies at $125 to $250 an hour (layer3labs.io), with a second aggregator putting the same two tiers higher, at $150 to $350 for independents and $150 to $300 for boutiques (aidolsgroup.com), and a third putting freelance work at $100 to $300 an hour (lazige.agency). Day rates are reported at $600 to $1,200 for a direct freelance hire and $1,500 to $2,500 for an agency-placed contractor (lazige.agency). The sources disagree on the direction of travel as well: one reports rates rising 10 to 15 percent a year since 2024 (aidolsgroup.com) and another 12 to 18 percent (layer3labs.io). Treat the disagreement as the finding, because none of these figures come from the firms they describe and none of them is a price you can hold anyone to. Where it loses: nobody owns the outcome. A contractor delivers what was specified, and in this category the specification is the hard part. If the spec is wrong the contractor still gets paid and you still have the problem.Hands for hireYou own the spec
06Doing nothing yet.This wins far more often than any vendor page admits, and it wins for one specific, checkable reason rather than out of caution. Every one of the six other options has to read your data. If the data any system would query is fragmented across ERP, MES and QMS with no shared identifier, or is simply out of date, then every option above spends the first and largest part of its budget doing data cleanup you could have scoped as its own project at a fraction of the price. Two independent research findings point at the same root cause. RAND's 2024 report, The Root Causes of Failure for Artificial Intelligence Projects and How They Can Succeed, reportedly built on interviews with 65 experienced data scientists, is cited as finding that more than 80 percent of AI projects fail, roughly double the rate of non-AI IT projects. MIT's NANDA report, The GenAI Divide: State of AI in Business 2025, is cited as finding that 95 percent of generative AI pilots delivered no measurable profit-and-loss impact within roughly six months. Both are REPORTED: we read consistent secondary coverage of both and did not read either primary document, and rand.org returned an HTTP 403 to our own fetch, which is a failure to read the source rather than evidence about it either way. Where doing nothing loses: when the constraint is real, quantified and getting worse, waiting is just a slower version of paying for it.No spendFix the data first
07A boutique commissioning house.We are one, so read this row with the appropriate suspicion. It wins when the function is bound to workflow that a horizontal product does not model well, when the buyer wants to own the resulting code rather than rent access to it, and when a single fixed fee is a better shape than either a salary or an hourly meter. ColabContent commissions builds at a fixed fee of $45,000 to $180,000, one time, with a working prototype on the manufacturer's own data before any payment changes hands, and with code, prompts, models, datasets and runbook handed over at the end. More than forty commissions have been delivered across the practice and more than 6,000 live calls have been handled across every voice system commissioned. Where it loses, stated plainly: no manufacturing engagement is published yet, so if a same-vertical reference is a requirement, this row fails your screen and should. It also loses when the need is a turnkey subscription with no engineering involvement, when the work is permanent rather than a bounded build, and when nobody at the plant will own the system after handoff.Fixed fee, ownedNo manufacturing reference yet
