Indiana & Wisconsin Manufacturing Corridor: SolidWorks/Creo VAR Benchmarks, Custom Machine R&D Credits & PE Comity
Custom machine builders in Indiana and Wisconsin usually overspend in three places: named CAD seats that could float, staffing markups on controls engineers, and R&D credits lost to time-and-materials contracts. Moving 26 named SOLIDWORKS Professional users to 12 floating seats benchmarks at $42,256 a year saved. A fixed-price build contract can turn a disallowed design program into qualified research.
01PE licensing, firm rules and comity in Indiana and Wisconsin
Machine builders mostly need a PE seal for three things: equipment anchorage, mezzanines and platforms, and occasionally a pressure or lifting device that a customer's insurer wants reviewed. The boards are:
- Indiana: the State Board of Registration for Professional Engineers, administered through the Indiana Professional Licensing Agency under Indiana Code Title 25, Article 31.
- Wisconsin: the Examining Board of Architects, Landscape Architects, Professional Engineers, Designers and Professional Land Surveyors, attached to the Department of Safety and Professional Services (DSPS), under Wisconsin Statutes Chapter 443. Wisconsin requires business entities that practise engineering to hold a certificate of authorization; check the board's current rule for your entity type and the engineer who must be named.
For Indiana firm-level filings, confirm the current requirement with the Professional Licensing Agency before a vendor seals under a company name. Do not infer it from Wisconsin.
Both states apply the NCEES Model Law standard of responsible charge and accept NCEES Record holders for comity. Neither is in the 1.35x SE-mandatory group, so house formulas apply at 1.0x. A builder shipping a line to a customer plant in Illinois will need an engineer who can practise structural engineering there under the Illinois Structural Engineering Licensing Act, priced at 1.35x.
Example: a 6-station assembly cell shipped to Indiana, Wisconsin and Illinois customers, each needing anchorage for two pads. Indiana and Wisconsin: 4 x $2,600 = $10,400. Illinois: 2 x $2,600 x 1.35 = $7,020. Two extra states for the sealing firm: 2 x $425 = $850. Total: $18,270.
02SOLIDWORKS and Creo VAR benchmarks for corridor shops
Corridor shops commonly run SOLIDWORKS for machine design and Creo where an OEM customer mandates it. Most buy through regional VARs. The table below gives house benchmarks for 2025-2026, before any negotiation.
Compare term and perpetual over five years for SOLIDWORKS Professional:
- Term: 5 x $3,800 = $19,000 per seat, assuming no uplift.
- Term with a 9.5% annual uplift: $3,800 + $4,161 + $4,556 + $4,989 + $5,463 = $22,969.
- Perpetual: $5,490 + (5 x $1,595 maintenance) = $13,465.
The perpetual path looks cheaper, but check whether your VAR still offers new perpetual licenses for your product and region, and what reinstatement costs if maintenance lapses. Lapse penalties of $500 to $1,500 or more per seat are common. Price both in writing before the renewal date.
| Product | Benchmark per seat per year | Observed range | Check at renewal |
|---|---|---|---|
| SOLIDWORKS Standard (term) | $3,150 | $2,820-$3,480 | Uplift cap in writing |
| SOLIDWORKS Professional (term) | $3,800 | $3,456-$4,152 | Floating vs named mix |
| SOLIDWORKS Premium (term) | $5,100 | $4,716-$5,496 | Is simulation actually used |
| PTC Creo Design Essentials | $3,300 | $3,100-$3,500 | Module bundle contents |
| PTC Creo Design Advanced | $6,800 | $5,200-$10,600+ | Advanced Plus upsell |
| PTC Windchill PLM user | $2,100 | $1,200-$3,400 | Read-only vs author licenses |
Creo shops face a different trap. A Design Essentials seat at $3,300 is often sold alongside add-on modules, and an Advanced seat at $6,800 can be proposed for users who only need basic part and assembly modelling. Map each user's actual module use before renewal. Ten users moved from Advanced to Essentials save 10 x ($6,800 - $3,300) = $35,000 a year. Windchill is similar: read-only viewers on full author licenses are a common overspend. For shops that also outsource legacy drawing conversion, house offshore benchmarks are $14/hr for 2D and $18/hr for 3D, plus an 18% internal QA buffer; production drafting of this kind is not research, so it does not change the R&D credit math below.
03Floating seat math for a 26-engineer design office
Machine design offices rarely have every engineer in CAD at once. Engineers spend time on the shop floor, at customer sites for commissioning and in quoting. That is the case for a floating SolidNetWork License pool.
The house benchmark: floating seats carry a 24% premium over named seats, and a well-sized pool supports 2.6 engineers per seat at 75% peak concurrency.
- Current: 26 named Professional seats x $3,800 = $98,800
- Sized pool: 26 / 2.6 = 10 seats. Add 2 seats of headroom = 12 seats.
- Floating cost: 12 x ($3,800 x 1.24) = 12 x $4,712 = $56,544
- Saving: $98,800 - $56,544 = $42,256, or 42.8%
Do not size from headcount. Pull 90 days of license server logs and find the true peak. If peak concurrency is 15, buy 15 or 16 seats, not 12. Many shops find their named seats were used below 35% of the time, which is why the pool math works.
Watch two traps. First, the VAR may propose converting only some seats, leaving a mixed pool that is hard to audit. Second, home-use and old VM installs found during conversion can trigger a compliance letter. Clean them up before you ask for a quote. The CAD/PLM license audit calculator runs this math on your own numbers.
04Controls, commissioning and design staffing
Indiana and Wisconsin builders lean on contract PLC programmers, robotics integrators and commissioning engineers during build peaks. Typical agency bill rates sit in the $72-$135/hr band, using bill rate = base wage x (1 + markup) with markups of 45% to 62%.
Example: two controls engineers at a $55/hr base for a 6-month build and install (1,040 hours each).
- At 55% markup: $55 x 1.55 = $85.25/hr; 2 x 1,040 x $85.25 = $177,320
- At 45% markup: $55 x 1.45 = $79.75/hr; 2 x 1,040 x $79.75 = $165,880
- Difference: $11,440 on one build
Commissioning travel is where invoices drift. Agree in writing whether per diem, mileage and airfare are passed through at cost or marked up, and how travel hours are billed. If you plan to hire a contractor after the install, the conversion clause matters: 20% of a $114,400 salary is $22,880 before the step-down threshold.

05Custom machine R&D credits and the funded-research trap
Custom machines are often genuine research: new mechanisms, new cycle times, new controls logic with real technical uncertainty. The federal credit under IRC Section 41 nets about 7.9% of QREs. The problem is the contract. Under IRC Section 41(d)(4)(H), research is funded, and excluded, if the customer pays regardless of success. Time-and-materials builds usually fail that test. Fixed-price builds where the builder bears the cost of a failed design usually pass, provided the builder also keeps substantial rights to the know-how.
Example: a builder spends $600,000 of engineering wages on a fixed-price line, $90,000 on prototype parts consumed in testing and $100,000 on a US contract designer.
- QRE: $600,000 + $90,000 + ($100,000 x 0.65) = $755,000
- Federal net at about 7.9%: $59,645
- On a T&M contract the same work may produce close to $0.
State layers: Indiana offers a research expense credit, generally 15% on the first $1M of qualifying increase and 10% above, with an alternative method available. Wisconsin offers a research credit of about 5.75% of qualifying expenses above half the prior three-year average, with a partly refundable portion. Check both departments of revenue for the current rates and refund rules.
| Contract type | Who bears failure risk | Likely QRE treatment | Federal credit on $755,000 |
|---|---|---|---|
| Fixed price, builder keeps rights | Builder | Generally qualifies | about $59,645 |
| Fixed price, customer owns all IP | Builder | At risk: substantial rights test | review needed |
| Time and materials | Customer | Often funded, excluded | close to $0 |
| Cost-plus with performance bonus | Shared | Fact-specific | review needed |
06Corridor buyer checklist
- Pull 90 days of license server logs before any SOLIDWORKS or Creo renewal conversation.
- Ask the VAR for term and perpetual pricing over five years, with the uplift cap in writing.
- Clean up home-use and legacy VM installs before requesting a floating conversion quote.
- Verify the sealing engineer on the Indiana and Wisconsin boards and confirm firm requirements in each.
- Budget 1.35x and an Illinois-licensed structural engineer for any Illinois ship-to site.
- Fix commissioning travel and per diem treatment in the staffing MSA.
- Write fixed-price terms and IP retention into machine contracts you expect to claim as research.
- Estimate federal and state credits with the R&D credit calculator.

Questions buyers ask
How much does a SOLIDWORKS Professional seat cost in Indiana or Wisconsin?
The house benchmark for a SOLIDWORKS Professional term seat is $3,800 per year, within a typical 2025-2026 range of $3,456 to $4,152. Regional VAR quotes vary by seat count and timing, so compare at least two quotes and get the renewal uplift cap in writing.
How many floating CAD seats does a machine design office need?
A well-sized floating pool supports about 2.6 engineers per seat at 75% peak concurrency, but size it from 90 days of license server logs, not headcount. Floating seats carry about a 24% premium, so 26 named seats at $3,800 versus 12 floating seats at $4,712 saves $42,256 a year.
Does a custom machine builder qualify for the R&D tax credit?
Often, if the design involves real technical uncertainty and the contract is fixed-price with the builder bearing the cost of failure and keeping substantial rights. Time-and-materials work is commonly treated as funded research under IRC Section 41(d)(4)(H) and excluded.
Does Wisconsin require a certificate of authorization for engineering firms?
Wisconsin requires business entities that practise engineering to hold a certificate of authorization from the examining board under DSPS, with a responsible professional engineer named. Check the board's current rule for your entity type before a vendor seals under a company name.
What does an Indiana R&D tax credit look like?
Indiana's research expense credit is generally 15% on the first $1 million of qualifying increase in research spend and 10% above that, with an alternative calculation method available. Check the Indiana Department of Revenue for the current rules before filing.
