Three ways to make money together01 02 03
Choose the partnership that fits your business.
Whether you bring client relationships, delivery capacity, or both, there is a practical way to collaborate. Each engagement is agreed in writing before work begins.
Business development
Refer a project. Share in the value.
Introduce a company struggling with tolerance-stack backlog, errors or design revisions. Rev4 scopes and delivers the project. Qualified referral compensation can be negotiated for an accepted, completed engagement.
Best for: consultants with industry relationships who do not want to perform every calculation.
Specialist subcontracting
Get paid to do the engineering.
Join a Rev4-led project as an independent engineer. Complete analysis, review existing stacks, resolve dimensional issues or support supplier changes. Scope, rates and deliverables are established per project.
Best for: mechanical engineers, GD&T specialists and tolerance-stack practitioners.
Joint client delivery
Bring your client. Expand your offering.
Keep leading the customer relationship while collaborating with Rev4 to handle drawing-data extraction, analysis volume and revision tracking. Commercial ownership and delivery responsibilities are agreed upfront.
Best for: independent engineering firms that want to accept bigger or recurring programs.
A delivery advantage, without building new software
Do more engineering. Spend less time rekeying drawings.
IrisX helps capture and compare engineering drawing data; Tolerance360 supports stack calculations and result management. Your engineering judgment remains essential.

IrisX — 2D drawing intelligence
Capture dimensions, tolerances, GD&T and changes from PDFs, scans and legacy engineering drawings, even when no 3D model exists.
▦
Tolerance360 — stack workflow
Support dimensional calculations, review, Excel-friendly delivery, a shared record of analyses and revision management.
✓
Your expertise stays essential
You define requirements, interpret the chain, validate assumptions, assess risks and explain engineering decisions.
Software access, training, licenses and permitted data use are discussed for each partnership. No entitlement is implied by submitting an inquiry.
From analysis to managed delivery
Show prospects how your expertise becomes an engineered deliverable.
A two-step Tolerance360 workflow: complete the tolerance analysis in Excel, then organize the engineering work and its records in the WorkBench. Your engineering judgment drives the process.
01
ANALYZE & REVIEW
Build and check the tolerance stack
Use familiar Excel workflows to define, calculate and review tolerance stacks, methods, assumptions and results.
02
ORGANIZE & DELIVER
Keep parts, stacks and revisions together
Manage the related engineering data and analysis records so studies are easier to review, maintain and hand off.
Where IrisX fits: When source dimensions must be recovered from PDF or scanned 2D drawings, IrisX can extract and track that information upstream. Tolerance360 is the tool used for tolerance-stack analysis and management.
What you can sell
Six engineering problems customers already understand.
✓
Review & correct Excel tolerance stacks

▤
Recover engineering data from 2D
Help clients who have PDF or scanned drawings but no accessible native CAD.
◉
Provide temporary dimensional capacity
Support clients who need specialized assistance without permanent headcount.
↗
Grow into recurring service
Move from a focused review or backlog pilot into an ongoing retainer.
An uncomplicated path
How partnership starts
You retain your independence. We align on the customer, the engineering scope and the commercial arrangement before delivery.
01 · INTRODUCE
Tell us your specialty
Share your background, industries, software experience and preferred engagement model.
02 · ALIGN
Choose how to work
Discuss referrals, paid project delivery or joint-client collaboration.
03 · AGREE
Define business terms
Document role, rate or referral compensation, confidentiality and client responsibilities.
04 · DELIVER
Earn through work
Contribute to a qualified project when an engagement is available and approved.
Commercial terms, opportunities and assignments are subject to agreement and availability. This is an invitation to discuss partnership—not a job offer, guarantee of leads, preset referral percentage or grant of ownership/equity.
Frequently asked questions
Keep your independence.
Can I bring my own clients?
Yes, this is a possible collaboration model. Client ownership, non-solicitation requirements, confidentiality and delivery responsibilities should be defined in a written agreement before work begins.
What if I only want to refer leads?
Qualified referral arrangements may be offered. Any compensation, trigger for payment, exclusions and duration would be agreed before a referral is made.
Do I need to learn Tolerance360?
Not for a referral-only relationship. Project-delivery work may involve appropriate tools and onboarding, depending on your role and client requirements.
Will Rev4 provide me with customers?
Projects may arise through Rev4 or through your own network; volume and timing are not guaranteed. We match opportunities by expertise, availability and agreed client requirements.
Can I use my own software or templates?
Possibly. We define acceptable tools, output requirements and information security arrangements for each engagement.
