MasterControl vs Greenlight Guru: 2026 Quality Choice

Key Takeaways

• MasterControl and Greenlight Guru are both still sold under those names. Greenlight Guru acquired Ultralight Labs and Enzyme in 2025 and kept its own brand. MasterControl added Qualer's calibration and maintenance tools beside its quality and manufacturing suites.

• Choose Greenlight Guru when the file you must defend is a medical device design history, an ISO 14971 risk file, and post-market quality events under the device quality rule. Choose MasterControl when that file also has to include batch execution and equipment status.

• Greenlight Guru publishes annual subscription floors. MasterControl's pricing page does not publish a dollar price. Treat MasterControl as quote-based until a written quote lists modules, users, and services.

• A published floor is not a first-year total. On Greenlight Guru's pricing page, implementation and clinical study-build are priced separately, while validation documents, a named success manager, training, and support are included in the subscription.

• The quality system stores the controlled record. A hold in inventory, a pause on a change, or a training gap outside that system is a second workflow. Someone still has to review the exception before stock or a release moves.

• Device plants are already under the Quality Management System Regulation. Inspections no longer follow the old technique. Confirm your procedures match the current inspection program before you compare software screens.

Start with the record an inspector will ask for

An electronic quality management system is the software that keeps the approved procedure, the training proof, and the quality event together so a plant can show who approved what, and when. TL;DR: pick Greenlight Guru for a medical device design history and event file with a published subscription floor, and pick MasterControl when the same plant also needs manufacturing execution and calibration on a named-user quote.

The search is still the right pair of names. Neither product was renamed or withdrawn. Greenlight Guru's own note, updated July 29, 2026, says Ultralight Labs is now fully part of Greenlight Guru and that those capabilities sit in its quality management and product development solutions, and the same page describes service to medtech customers: 1,000+ companies according to Greenlight Guru (2026). On July 24, 2025, Greenlight Guru announced it had acquired Enzyme, a quality system founded in 2017, and said the Ultralight Labs deal had closed the prior month, according to PR Newswire (2025). The release also says Greenlight Guru is backed by JMI Equity. Buyers who still have an Enzyme login should ask which records moved, because the pricing page a new buyer sees is Greenlight Guru's.

MasterControl's path is a product-line add, not a rename. Its Qualer page describes one life-sciences platform that unites a quality system, a manufacturing execution suite, and a maintenance system after the Qualer acquisition. The quality, manufacturing, and asset names on its pricing page are Quality Excellence, Manufacturing Excellence, and Asset Excellence.

The regulatory clock already turned for device makers. QMSR effective date: February 2, 2026 according to FDA (2026). On that date the FDA retitled 21 CFR Part 820 as the Quality Management System Regulation, incorporated ISO 13485:2016 by reference, stopped using the Quality System Inspection Technique, and began inspections under compliance program 7382.850. The rule applies to finished device manufacturers who intend to sell. A software choice that cannot show design, production, complaint, and supplier records as one story is a weak answer in that inspection.

Pharma and biotech plants live under a different set of manufacturing rules. They still need controlled documents, training, deviations, and batch records. They do not automatically need a device design-history product. That split, more than a logo, is the decision.

Who this is for

This comparison is for a quality lead at a regulated manufacturer who is close to a signature. You already know you need controlled documents, training, and a closed path for complaints, nonconformances, corrective actions, and changes. You are deciding whether the painful record is the device design history or the batch and the instrument.

You are in the right place if an auditor can ask for a requirement, the risk control, the complaint, and the supplier in one sitting, or if production can be stopped because a gauge was out of calibration. You are also in the right place if finance wants a number you can read before the sales call, and you are willing to hear "quote" when a vendor will not print one.

Red flags: the plant is outside life sciences and medical devices and needs a general factory quality system; the only pain is a shared folder of procedures with no events and no inspection on the calendar; you will not accept a quote and you want every module priced on a public checkout page. A dental practice choosing an in-house membership plan is a different buy, covered in dental membership platforms for in-house plans.

Use this test before the demo. Write the three records an inspector asked for last time, or will ask for next time. If two of the three are design inputs, risk controls, and complaint files, stay with the device suite. If two of the three are the batch record, the equipment status, and the deviation, weigh the manufacturing and asset suites heavily. If the third record lives in inventory, purchasing, or a training spreadsheet outside either product, budget a reviewed handoff. Do not assume the quality system vendor runs that handoff.

How we evaluated these quality systems

We scored the decision from public pages opened for this guide, not from a hands-on trial. A capability is listed only when an official vendor page stated it. A price is listed only when that vendor's own pricing page stated it. Where the vendor asks you to call, the price is quote-based. Review scores are included only from a review page that showed a count. No customer, quote, or deployment was added beyond names a vendor or a news release already printed.

The weights match what a quality lead argues about in the buying meeting. Scope gets the most weight because a strong complaint module does not fix a missing batch record, and a strong batch record does not build a design history. Quality events are next, because that is the daily work. Design-and-risk traceability and manufacturing-and-asset connection share the next band, and most plants lean on one of them. Validation evidence matters because a cloud release still has to be defended. The readable price is real, and it is last, because a cheap floor that omits the record you need is not a savings.

A row is satisfied when at least one official page we opened states the capability in plain language. "Not stated on the pages we opened" is not a claim that the feature is absent. It means you should make the salesperson show it in the quote and in a scripted walkthrough. Weights sum to 100%. We did not assign star scores to either vendor. A weighted feature score built from adjectives would pretend a precision these pages do not support.

What each vendor sells after the 2025 deals

MasterControl, founded in 1993, is a private company based in Salt Lake City with 501 to 1,000 employees, and Gartner Peer Insights shows a peer rating: 4.4 across 140 ratings for MasterControl Quality Excellence according to Gartner (2026). That rating is not a head-to-head score against Greenlight Guru. Gartner describes Quality Excellence as a life-sciences platform for quality events, documents, training, and audits, aimed at pharmaceuticals, biotechnology, and medical devices. The company's own pricing page says it is trusted by customer base: 1,200+ companies according to MasterControl (2026). A June 23, 2025 analyst briefing put annual recurring revenue: $200 million at MasterControl, with more than 1.25 million users, and said about 90% of customers were in life sciences, according to Axendia (2025). Use the pricing-page customer figure when you need the company's current public count. Use the 2025 briefing for revenue and users, and do not blend the two into a new number.

Best fit for MasterControl is a life-sciences plant that wants documents, training, and quality events on Quality Excellence, production records on Manufacturing Excellence, and calibration plus maintenance on Asset Excellence. The pricing page says Quality Excellence and Manufacturing Excellence use a named-user license, with packages from pre-configured and pre-validated setups for emerging companies to broader enterprise packages. The Qualer page says the quality offering is backed by platform history: 25+ years according to MasterControl (2026). Manufacturing Excellence, on that same page, covers inbound materials, work orders, batch execution, and review by exception. Asset tools cover tracking, maintenance, service requests, and vendors. Electronic logbooks are part of the manufacturing story on that page.

Limits are practical. The pricing page does not print a dollar amount, so any per-user figure you have heard elsewhere is not a price we will repeat. Design controls and ISO 14971 are not the center of the pricing-page description. Part 11 is not named on that page. The Axendia briefing calls the platform GxP-aligned and says customer data is not used to train its model. Implementation shape depends on the package. Validation Excellence Tool and Validation on Demand are included, and extra validation training is an optional purchase. MasterControl's help topic says an API license is required and that REST documentation opens from the customer's own site, as described in MasterControl's API help. Ask the quote to list modules, named users, environments, validation help, and the API license as separate lines.

Best fit for Greenlight Guru is a medical device company, including software as a medical device, whose audit story runs from requirements and risk through complaints, corrective actions, suppliers, and sometimes a clinical study. The pricing page says the suite aligns to ISO 13485, FDA QMSR, ISO 14971, and IEC 62304. It publishes document control with Part 11 electronic signatures, change control that can issue retraining, training by role, supplier controls, design controls, ISO 14971 hazard analysis and failure modes, parts and inventory, and Jira and GitHub links. Post-market events on that page include complaints, corrective and preventive actions, nonconformances, audits, and supplier monitoring. Clinical data capture is a separate subscription. Security notes on the page include ISO 42001 for the AI management system, ISO 27001, ISO 9001, and SOC 2, and the page says customer data is not used to train AI models.

Limits follow from that focus. The pages we opened do not describe a manufacturing execution suite or a calibration system of the kind MasterControl advertises after Qualer. The subscription floor is not the quote. The pricing page says the price depends on products and capabilities, and that quality implementation and clinical study-build are priced separately. Validation documents, a dedicated customer success manager, training resources, and support are included. Each release includes updated validation documentation, and the customer completes a short installation qualification rather than a fresh validation project. A custom connection is different. Greenlight Guru's API page says the buyer owns validation of an integration the buyer builds, under the buyer's own risk-based approach, while records created through the API stay in the audit trail.

Capabilities you can verify on a public page

Read the matrix as a paperwork test. Each cell reflects pages opened for this guide. Where a cell says the page did not state the point, put the question in the demonstration script and in the quote. Do not fill the blank from a forum.

A quality lead who only compares "CAPA: yes" will call this a tie. The tie breaks on the rows for design history, batch execution, and calibration. Those three rows are why a device design team and a sterile-fill plant can both be regulated and still buy different systems.

Supplier quality is on both stories, and it fails in the warehouse before it fails in the audit binder. If incoming material is the actual fire, pair the quality-system choice with a way to flag raw-material shortages before the batch. The quality system can hold the supplier record. It does not, by itself, warn planning that a lot should not be issued.

Budget the quote, not the rumor

Pricing checked October 12, 2026. MasterControl's pricing page tells you to contact sales and describes a named-user license. No dollar figure appears there, so MasterControl stays quote-based. Do not drop a third-party "starts at" number into a budget. Ask for the quote to split Quality Excellence, Manufacturing Excellence, Asset Excellence, environments, validation training, data migration, and the API license.

Greenlight Guru's pricing page does print floors. eQMS packages: $12,000 per year and EDC subscriptions: $9,000 per year according to Greenlight Guru (2026). The same page says quality and product-development subscriptions start at that $12,000 figure, that your price depends on the products and capabilities you need, and that implementation and clinical study-build are quoted separately. Validation documents, a customer success manager, training, and support sit inside the subscription. The page also publishes a comment from Daniel Powell, CEO of Spark Biomedical, that the software is expensive on day one because a year of setup work is already in place. Treat that as one customer's published remark, not as a measured payback.

First-year cash is the subscription or the quote, plus implementation, plus the time your own people spend on migration and on any connector. Greenlight Guru's $12,000 floor can be the quality and product-development start, and a plant that also runs a study adds the $9,000 EDC floor only if that product is in scope. Adding those floors produces a $21,000 published starting point before implementation. That addition is arithmetic on the two published floors. It is not a quote, and it is not a discount. MasterControl's first year cannot be totaled from a public price. Put both vendors' implementation estimates in the same spreadsheet before you call one of them cheaper.

Procedure text is a separate cost. Teams that write their own product procedures sometimes look at a SaaS writing-tool comparison. Teams that hire an outside shop for that writing look at an agency writing-tool comparison. Neither shortlist replaces the quality system, and neither one stores the signed record.

An illustrative month of complaint files

This month is a sketch for a device plant, not a study and not a vendor benchmark. The plant logs 40 complaints. A specialist spends 1.5 hours assembling the linked product, risk, and supplier pages for each one. That is 40 times 1.5, which is 60 hours. At a loaded rate of $75 an hour, the assembly is $4,500 before anyone decides whether a complaint becomes a corrective action. If outcome data for the same device sits in Greenlight Guru Clinical, the public Subject API documents an enrollment object whose enrollments.subject field points at the subject on that study, as shown in Greenlight Guru Clinical's Subject API. A proposed export can attach that enrollment status to the complaint packet. The 60 hours do not vanish. A quality lead still reviews the 40 files. The $4,500 prices the retyping, not the judgment.

The four lines sum to $5,950 in this sketch. Only the first line is the retyping. The other three are review, training follow-up, and a check that the export matches the log. A quality system that already links the complaint to the product and the risk file attacks the $4,500 line. It does not, by itself, price the board review. Use your own rates. If your loaded rate is higher than $75, the same 60 hours cost more. If specialists already work inside one linked file, the 1.5 hours is the wrong assumption and the savings are smaller.

Moving a quality event into the plant

The quality system can close the event and still leave the warehouse, the change notice, and the training matrix in other tools. That gap is where a configurable layer above the quality system does the work. It is a proposal with prerequisites and a human check. It is not a live deployment and it has no measured savings.

When a released nonconformance export arrives, US Tech Automations reads it, matches the part to the inventory hold list, and writes a hold request that carries the event id. The trigger is the released export. The action is the match and the hold request. The output is a held lot plus a review packet. Prerequisites are an API key or a scheduled CSV from the quality system, a field map a quality lead has signed, and a parts list the warehouse already trusts. A person in quality confirms disposition before any stock status changes. Nothing in that path scraps material on its own.

The proposed US Tech Automations flow for a document release runs the other direction. The trigger is a change record reaching approved status. The action checks the training export for the named roles and, where a name is missing, opens an escalation task and holds the downstream release notice. The output is a change packet that lists who has not trained. The prerequisite is a training export by role, and a quality lead reviews the hold before anyone lifts it. The same pattern can watch a calibration export from an asset system and block a batch step when the gauge is out of status, again only after a person confirms the block is aimed at the right work order.

The homemade connector, fairly compared

Many plants will try to stitch this together in Zapier, Make, or n8n, or they will build it in-house. That is a fair alternative. Those tools can support run histories, retries, error branches, and audit evidence when someone configures them. The buyer then designs and owns observability, idempotency, escalation, access controls, and maintenance. A zap that files a complaint email can be enough when one person checks a folder every Friday and the auditor never asks how the hold was created. It gets thin when the same event is delivered twice, the part number is blank, or the only history is a task log nobody can export for an inspection.

A proposed US Tech Automations design would configure the difference around the event id. A second delivery of the same nonconformance would update the existing hold instead of opening another one. A failed match would escalate to a named quality role instead of failing quietly. Access to the map and the credentials would sit with quality and IT, not in one person's private login. The prerequisites are the same export or API key, a signed field map, and a reviewer for exceptions. The quality system vendor still stores the controlled record. This layer does not replace Greenlight Guru or MasterControl, and it does not sign the record for you.

Mistakes that show up at the first inspection

• Treating $12,000 as the full first year. Implementation is separate, and a clinical study-build is separate again.

• Putting a remembered MasterControl price in the spreadsheet. The vendor's pricing page is quote-based. Ask for the lines in writing.

• Buying a device design suite when the last three deviations were equipment status and batch review, or buying a manufacturing suite when the last finding was an incomplete design history.

• Assuming a connector is validated because the quality system is. Greenlight Guru's API page says a connection you build is your software to validate. MasterControl requires an API license before that work starts.

• Freezing procedures on the old inspection technique. Device inspections follow compliance program 7382.850, and a question can move from complaints into suppliers, audits, and management review.

• Letting one person own the only login that moves holds. When that person is out, the audit trail of the handoff is a private inbox.

Questions to settle before you sign

Are MasterControl and Greenlight Guru the same kind of product?

No. Both handle controlled quality records for regulated companies, and they center different records. Greenlight Guru's public suite is built for medical device quality, design controls, risk, and clinical data. MasterControl's public suite adds manufacturing execution and asset maintenance for life sciences beside the quality system.

Were either products renamed or discontinued?

No. Both names are current. Greenlight Guru acquired Ultralight Labs and Enzyme in 2025, and its July 29, 2026 note says Ultralight's capabilities now sit in quality management and product development. MasterControl still sells Quality Excellence and added Qualer's tools as Asset Excellence. If you are leaving Enzyme, ask for the written map of which records moved.

What price does Greenlight Guru publish?

Greenlight Guru's eQMS packages start at $12,000 per year, and EDC subscriptions start at $9,000 per year. The final number depends on products and capabilities. Implementation and clinical study-build are priced separately. Validation documents, a customer success manager, training, and support are included in the subscription.

Why is MasterControl quote-based here?

MasterControl's own pricing page does not list a dollar price. It offers a named-user license for Quality Excellence and Manufacturing Excellence and tells you to contact sales. Until a quote names modules and users, any other dollar figure is not a price you should budget.

Who should choose which vendor?

Choose Greenlight Guru when the inspection story is the device design history, ISO 14971 risk, and post-market events, with clinical data if you run a study. Choose MasterControl when quality events must sit beside batch execution and calibration on one vendor's platform. If you are outside life sciences and medical devices, look at a general quality system before you force either fit.

When NOT to use US Tech Automations?

Skip that extra layer when the quality system already routes the event, the training, and the signature, and nobody outside it needs a copy. Skip it when one checked folder move a week is the whole integration, and a person already reviews it. Skip it when you have no API key, no export, and no named reviewer for exceptions. A simpler tool that already holds the record wins those cases.

Can Zapier, Make, or n8n replace the quality system?

No. Those tools can move a file and keep run histories, retries, and error branches if you configure them. They do not become your design history or your batch record. You still own idempotency, access, escalation, and the audit evidence of the handoff. The quality system remains the system of record either way.

Where this leaves the choice

Write the record an inspector will request, then match the vendor that states that record on a page you can keep. For a device design history, risk file, and complaint path, Greenlight Guru's published suite matches, and you can start the budget from $12,000 per year before implementation. For batch execution and calibration beside quality events, MasterControl's three suites match, and the budget starts when the quote arrives. In both cases the signature inside the quality system is the controlled record.

If a released event also has to hold a lot or pause a change, design that handoff with an export or an API key, a signed field map, and a person who approves the exception. See how US Tech Automations configures this only as a configurable layer above the system you buy. Count the connector's validation as your work. Then compare the two quotes on the same lines: modules, users, implementation, validation help, and the first inspection you actually expect.
