DMAICPROCESS.AI turns Lean Six Sigma problem solving into an AI-guided SaaS product. A business owner describes a recurring process problem, uploads their data, and the platform walks them through Define, Measure, Analyze, Improve and Control. I built the custom plugin behind the AI workspace, rebuilt signup and billing on Stripe, cleaned up the site for search, and I look after it on a monthly retainer. It is live at dmaicprocess.ai.

The idea
The founder is an experienced Lean Six Sigma practitioner who wanted Black Belt-level problem solving to be available to every business owner, not only to companies that can pay consultants or fund years of training. The product had to take a real problem and real data and produce a complete, actionable improvement project in minutes rather than months.
The challenge
The site started on a commercial WordPress theme and a membership plugin. They covered the basics but were never meant to run an AI SaaS product:
- No AI product layer. There was no way to create DMAIC projects, generate content stage by stage or work with uploaded data.
- An outdated payment flow. Signup asked for raw card details on the site, did not reliably start recurring subscriptions, and left half-finished accounts when a payment failed.
- Fragile membership logic. Renewals, cancellations and plan changes drifted out of sync between the payment provider and the site.
- Template demo content in Google. Sample products, portfolio pages, blog posts and theme fragments were public and indexed, diluting the brand.
- No safety net. There were no off-site backups or uptime alerts for a site about to take paying customers.
My approach
One rule shaped the work: build on top of the platform and never edit vendor files. Every custom feature lives in a dedicated plugin, so theme and plugin updates cannot overwrite it. I worked in short verification loops: each fix was tested on the live site before I reported it done, and the founder approved every customer-facing change first.
What I built
A custom AI DMAIC plugin
- A private dashboard where members create and manage DMAIC projects
- Section-by-section generation with the OpenAI API, with regenerate and edit options
- Word and Excel uploads used as context for the AI analysis
- Starter projects based on real Six Sigma case examples
- Saved project history and export-ready reports
- Plan-based access: the free plan unlocks Define, and paid plans unlock all five stages, more projects and larger uploads
Secure payments and subscriptions
- Stripe Checkout replaced on-site card collection, so card data never touches the website
- Monthly and yearly recurring subscriptions, with accounts created only after payment is confirmed
- Upgrades that cancel the old subscription only after the new one is paid, so no member is left without a plan
- Stripe webhooks that keep renewals, failed payments and cancellations in sync with membership access
- A full end-to-end run in Stripe test mode: signup, payment, account access, logout, login and AI generation, with no real charges
Account and UX fixes
- Fixed a login failure caused by a script-loading conflict in the membership plugin
- Replaced plain-text passwords sent by email with secure, single-use reset links
- Cleaned up the registration form and added proper Terms and Privacy links
- Fixed a signup bug that stopped new customers from logging back in after paying
Design and front end
I built custom Elementor homepage sections that explain the DMAIC process clearly, rebuilt the monthly and yearly pricing sections with consistent plans and prices, and fixed layout problems in the theme’s pricing components.
SEO cleanup
- Removed leftover template content: sample products, portfolio and service pages, and unrelated blog posts
- Returned “410 Gone” for more than 50 removed and template URLs, including theme fragments that served duplicate copies of the homepage
- Kept login, registration, dashboard, cart and checkout working but out of search results
- Cut the sitemap down to the real pages and resubmitted it in Google Search Console
- Fixed heading structure (one H1 per page), added image alt text, and set focus keywords, titles and meta descriptions in Rank Math
Reliability and maintenance
Scheduled off-site backups, uptime monitoring with email alerts (including a check that catches error pages, not only full outages), removal of unused and risky plugins, regular updates to WordPress, plugins and PHP, and ongoing security reviews.
The result
- A working AI SaaS product. Members turn a business problem into a complete DMAIC improvement project inside the platform.
- Recurring revenue that works. Customers subscribe through Stripe Checkout with true recurring billing on Free, Standard and Premium plans.
- A verified customer journey. The founder tested the whole flow, from signup to AI generation, and confirmed it works end to end.
- A clean site for launch. Template leftovers are gone, and Google now sees only the real DMAICPROCESS.AI pages.
- A safety net. Backups, monitoring and a documented maintenance process are in place.
Could this work for your product?
If you have a WordPress site that needs to become a real product, with AI features, paid subscriptions or a cleanup before launch, this is the kind of work I do: extend the platform with a proper plugin instead of fragile edits, wire Stripe billing that handles the edge cases, and explain every change in plain language.
