What Is QA as a Service (QAaaS)? How It Works and When It Fits

QA as a service (QAaaS) is software testing you buy as a managed service instead of hiring testers: a provider plans the testing, runs it, reports what it finds and is accountable for the result. It usually covers manual, automated, API, mobile, security and accessibility testing, sold as a monthly plan, a one-off audit or a dedicated team. It fits teams that ship often without a QA department.

If you would rather have it done for you, see how RAITHub would test this below, or go straight to the QA as a service overview.

What does QA as a service actually mean?

QA stands for quality assurance: the work of checking that software does what it should, for every kind of user, before real customers find out that it does not. "As a service" means you pay for that outcome as a running service, not for a person on your payroll.

The difference matters. When you hire a tester, you also take on everything around them: the test plan, the tools, the devices, the reporting format, holiday cover and their career. When you buy QA as a service, the provider brings all of that, and you judge them on what reaches you: clear bug reports, tests that run on every change, and a sign-off you can trust before a release.

The model has grown alongside a change in how testing is done. In the 2025 World Quality Report, published by OpenText with Capgemini and Sogeti from a survey of more than 2,000 senior executives, 89% of organisations said they were piloting or deploying generative AI in quality engineering, but only 15% had scaled it across the enterprise (Capgemini, World Quality Report 2025). Tools are changing fast; the judgement about what to test, and the discipline to keep doing it, is still the scarce part. That judgement is what a QA service sells.

Which kinds of testing does a QAaaS provider cover?

A full QA service covers five areas. Ask any provider which of these they actually deliver, because many cover only one or two.

Type of testing	What it answers	What you should receive
Manual and exploratory testing, plus UAT support	Does the product make sense and work for a real person, including the paths nobody scripted?	Test charters, bug reports with exact steps and evidence, a release sign-off
Mobile app testing on iOS and Android	Does the app work on the phones your users actually own?	A device matrix, results per device and OS version, real-device evidence
Web application security testing	Can one user see or change another user's data? Are common weaknesses present?	Findings mapped to OWASP guidance, each with a severity and a fix
Accessibility audits	Can people using a keyboard, screen reader or zoom complete each journey?	Issues mapped to WCAG 2.2 AA success criteria, each with its fix
Automation, API and performance testing	Will the next change break something that worked yesterday? Does it hold under load?	Tests in your repository, running in your CI, with performance budgets

Two of these need an honest boundary. Application security testing follows the OWASP Web Security Testing Guide, but it is not the same as a certified penetration test, and it produces no compliance attestation. If a customer contract or PCI DSS requires a CREST- or PCI-accredited pentest, you need an accredited firm for that report. Likewise, an accessibility audit against WCAG 2.2 tells you what fails and how to fix it, but no audit certifies legal compliance with the ADA, the European Accessibility Act or Section 508. That is general information; confirm your obligations with your adviser.

How does QA as a service work, step by step?

A good engagement follows the same shape whether it lasts two weeks or two years.

1. Audit. A short call to learn the product, the users, how often you release and how the last few bad releases were found.
2. Test strategy. A written plan: which journeys matter most, which test types apply, which browsers and devices, and what "ready to release" means for you.
3. Access and environments. A staging environment with production-like settings, test accounts for every role, and realistic seed data. Testing without these is mostly waiting.
4. Test cycles. Each release, or each sprint, is tested against the plan. New features get exploratory testing; existing journeys get regression checks.
5. Automation. Checks you run on every release move into automated tests that run in your CI pipeline, so they stop costing time each cycle.
6. Reporting and review. Bugs go into your tracker with steps to reproduce. A regular report shows what was tested, what failed and what changed, and the plan is adjusted.

What are the ways to buy QA as a service?

There are three common models, and they suit different moments in a product's life.

Model	How it works	Choose it when
Monthly QA plan	A set scope of testing each month: regression on each release, exploratory testing on new work, growing automation	You ship regularly and want quality checked on every release without a QA hire
Fixed-price one-off audit	A defined scope, for example a pre-launch QA pass, a security review or an accessibility audit, with a written report	You have a launch, a sales deal or a customer questionnaire with a date on it
Dedicated QA team	Testers who work on your product full time, managed and billed monthly by the provider	Your product and release pace need more than a plan's fixed scope covers

What each model costs on the open market, and what moves the price, is covered in QAaaS pricing. How a dedicated team differs from a group of freelancers is covered in the dedicated QA team guide.

How is QAaaS different from outsourcing testers or staff augmentation?

The difference is who manages the work and who answers for the outcome.

• Staff augmentation places testers inside your team, under your managers. You decide what they test and you carry the result. The vendor supplies people.
• Outsourced testing by the hour buys time. You pay for hours spent whether or not the test suite gets stronger.
• QA as a service buys a managed result. The provider owns the plan, the method, the reporting and the people, and is judged on whether releases get safer.

RAITHub offers the third kind only. Testers on a RAITHub QA engagement, including a dedicated team, are managed by RAITHub and are never placed under a client's management. For a fuller comparison with hiring your own QA engineer, read in-house QA vs outsourced QA vs QAaaS.

Buy, build or hire?

QAaaS is one of four routes to tested software. Each is right for someone.

Route	What it costs on the market	Choose this when	Watch out for
A tool or SaaS testing platform	Cloud browser and device testing starts at $29 to $39 a month for one user, and $150 a month for a five-user team plan (BrowserStack pricing)	Your developers already write tests and only need devices, browsers or a runner	A tool does not decide what to test or read the results
Freelancers or crowdtesting	Upwork lists a median of $35 an hour for QA engineers, typically $20 to $60 (Upwork QA engineer rates)	A short, well-defined burst of testing, such as one release or one device sweep	Knowledge leaves with each freelancer; quality varies by person
An in-house QA hire	The US median wage for QA analysts and testers was $104,300 in May 2025, before benefits and tools (US Bureau of Labor Statistics)	QA is core to the product and you can recruit, manage and keep a QA lead	One person cannot cover security, accessibility, mobile and automation
A managed QAaaS team	Quoted per scope: a monthly plan, a fixed audit or a dedicated team	You ship often, need several kinds of testing, and do not want to build a QA department	Make sure tests and reports live in your systems, not the provider's

When does QAaaS fit, and when does it not?

It fits when the gap is QA capacity and judgement, not tooling.

• It fits a startup or scale-up with developers but no tester, where developers test their own work and releases still break things for users.
• It fits a team with a launch, an enterprise deal or an accessibility requirement coming, and no one who has done that kind of testing before.
• It fits a product with web and mobile clients, where one in-house hire could not cover both plus security and accessibility.
• It does not fit a team whose developers already keep a healthy automated suite and only lack device coverage. Buy the tool.
• It does not fit when the real problem is the code itself: if every fix breaks two other things, start with a code rescue diagnostic rather than more testing.

If you are not sure which side you are on, the pre-launch QA checklist is a quick way to see how much of the work your team already covers.

Why RAITHub for QA as a service?

Because RAITHub's QA comes from engineers who build and run production software, and its test counts are counted in real repositories.

• Measured test suites. PropDesk, the property management platform RAITHub built, runs 1,024 automated tests. Sundor Skin, a B2B wholesale platform, runs 530+. TheSkinProof, the founder's own venture rather than a client, runs 750+, and this website runs 400+ in CI.
• The full scope in one place. Manual and exploratory testing with UAT support, mobile testing on real devices and device clouds, web application security testing, WCAG 2.2 accessibility audits, and automation, API and performance testing.
• Findings that come with fixes. Every bug report includes steps to reproduce and, where the cause is clear, the likely fix.
• Everything stays yours. Tests live in your repository, IP is assigned to you, and an NDA is standard.

RAITHub has no QA case study yet beyond those test counts, so judge the service on the free audit and a written scope.

When don't you need RAITHub for QA?

• When you need a CREST- or PCI-accredited penetration test report. RAITHub's security testing is application-level and produces no attestation.
• When you need a certificate of legal accessibility compliance. No honest audit can give one.
• When you want testers placed in your team under your own managers. RAITHub does not offer staff augmentation.
• When you need mobile apps built, not tested. RAITHub tests mobile apps but does not develop them.
• When your developers already test well and you only need more devices. A device cloud subscription is cheaper.

How RAITHub would test this

For a typical product with a web app, an API and possibly a mobile client, a RAITHub QA engagement looks like this:

• Scope: name the three to seven journeys that make money or hold data; agree the test types (manual, mobile, security, accessibility, automation) and the browser and device matrix.
• First cycle: a baseline pass of exploratory and regression testing, with every bug logged in your tracker with steps, evidence and severity.
• Gates: the most important journeys automated and set to block a merge in your CI when they fail.
• Specialist checks: security and accessibility reviews against OWASP guidance and WCAG 2.2 AA, where they are in scope.
• Rhythm: a regular report of what was tested, what failed and what changed, and a review of the plan.

Timeline: a one-off audit is fixed in scope and dates before it starts; a monthly plan or dedicated team runs month to month. You receive: a test strategy, bug reports, automated tests and CI configuration in your repository, a handover document, full IP and an NDA. Next step: a free 15-minute audit call, then a written fixed quote. RAITHub publishes no rates.

To start, tell RAITHub about your product and release pace. If you need a single pre-launch, security or accessibility audit, use the one-off audit form instead.

Frequently asked questions

What does QAaaS stand for?

QAaaS stands for quality assurance as a service: software testing delivered as a managed service, where the provider plans, runs and reports the testing, rather than you hiring and managing testers yourself.

Is QA as a service the same as outsourced testing?

Not quite. Outsourced testing often means renting testers by the hour. QA as a service means the provider owns the method and the result: the plan, the reporting, the automation and the release sign-off.

Is QA as a service the same as staff augmentation?

No. Staff augmentation places testers under your management. In QAaaS the provider manages the testers and answers for the outcome. RAITHub offers QAaaS only, never staff augmentation.

Does QA as a service include security and accessibility testing?

It can. RAITHub's covers web application security testing against OWASP guidance and accessibility audits against WCAG 2.2 AA. Neither is a certified pentest or a legal compliance certificate.

Can a QAaaS provider test mobile apps?

Yes. RAITHub tests iOS and Android apps on real devices and device clouds. It does not build mobile apps, so fixes go back to your own mobile developers.

How much does QA as a service cost?

It depends on scope, release pace and test types. Marketplace QA engineers typically charge $20 to $60 an hour, and manual QA in North America runs $80 to $150+ an hour (QA Madness). RAITHub quotes a fixed price after a free audit.

Who owns the tests if we stop working together?

With RAITHub, you do. Automated tests and CI configuration live in your repository, and the IP is assigned to you, so the suite keeps protecting you after the engagement ends.
