Is your proofreading vendor ISO 9001 certified? What to ask before you buy
Table of contents
ISO 9001 certification tells you something specific about a proofreading vendor: an independent auditor has confirmed their own quality management system meets an internationally recognized standard. It doesn’t tell you whether the software fits your regulatory needs, that’s a separate question, and one worth asking too. But it does tell you the company behind the tool builds and supports its product on a documented, repeatable process, not on good intentions.
For teams in regulated industries, that’s not a nice-to-have. It’s one more piece of evidence you can point to when someone, an auditor, a director, IT, or your own QA team, asks how you know this vendor is solid.
Why ISO 9001 matters when you're choosing proofreading software
ISO 9001 isn’t industry specific. It’s a certification of how a company runs itself: documented procedures, internal audits, corrective action when something goes wrong, and a third-party auditor checking all of it on a recurring basis. When a proofreading vendor holds it, you’re getting a vendor whose own house is in order, not just a vendor who says it is. IT teams have started insisting on vendors being ISO certified to ensure their teams are buying from a reliable partner.
If you work in medical devices, you’re probably also familiar with ISO 13485, the quality management standard for your own manufacturing and documentation processes. The two get confused constantly, mostly because they share a number format and a family resemblance. ISO 9001 speaks to your vendor’s operations. ISO 13485 speaks to yours. It’s worth asking a vendor about both but know you’re asking two different questions with two different answers.
What ISO 9001 tells you, and what it doesn’t
It tells you: the vendor has documented, auditable processes for building and supporting the product, version control, complaint handling, change management, supplier oversight. Someone outside the company checked, and it held up.
It doesn’t tell you: whether the specific software version you’re about to buy has been validated for your use. Certification and validation are related, but they’re not the same question. A vendor can be ISO 9001 certified and still leave you to figure out validation on your own, or they can hand you a validation package built for exactly this. Worth asking which one you’re getting before you sign anything. (We cover what a validation package should include on the TVT Workflow page, if you want the fuller picture.)
Questions to ask a proofreading vendor before you buy
A short list to bring into your next vendor call:
- Are you ISO 9001 certified? Can I see the certificate and its scope?
- How do you support software validation for regulated customers, and how long does that typically take?
- What’s your release cadence, and how are updates validated before rollout?
- Does every comparison generate an audit trail I can hand to an auditor?
- How do you support the documentation I need for ISO 13485, 21 CFR Part 820, or EU MDR on my side?
- Can I talk to a reference customer in a regulated industry like mine?
If a vendor can’t answer the first one plainly, the rest of the list gets a lot more important.
The buyer’s guide to content verification software for regulated industries
ISO 9001 certification is one important checkbox, but it’s not the whole vendor evaluation. Our Content Verification Buyer’s Guide walks through everything else worth weighing (validation support, audit trails, integrations, and more) before you commit to a proofreading vendor.
Where TVT stands
Schlafender Hase is ISO 9001 certified. That’s the short answer to the question this whole article is built around, but it’s worth showing, not just saying.
Every version of TVT is validated before release, and we provide a validation package with IQ and OQ test cases for medical device teams and other regulated customers who need to complete validation in-house, most complete it in one to two days. Every comparison TVT runs generates a full audit trail, so the paperwork exists before anyone asks for it, not after. And the certification sits alongside a track record you can check: TVT is used by 5+ global health authorities and 440+ pharma, medical device, and FMCG companies, with a 98% customer satisfaction rate.
None of that replaces asking the questions above of any vendor you’re evaluating, including us. It just means we’ve already done the work to have good answers, the same work covered in more depth in Medical Device Labeling Workflow and Medical Device Labeling Requirements, if you’re building out a fuller vendor evaluation.

A few quick answers on ISO 9001 certification, how it differs from software validation, and what it actually means for your vendor evaluation.
What role does ISO 9001 certification play in choosing a proofreading software provider?
ISO 9001 certification shows that a proofreading vendor’s own quality management system has been independently audited against an international standard, evidence of documented, repeatable processes for building and supporting the software, not a guarantee that the software itself is validated for your specific regulatory use.
Is ISO 9001 the same as ISO 13485?
No. ISO 9001 is a general quality management standard that applies to any organization, including your software vendor. ISO 13485 is specific to medical device manufacturers and covers their own product quality system. A vendor being ISO 9001 certified doesn’t mean you can skip your own ISO 13485 obligations, and vice versa.
Is Schlafender Hase ISO 9001 certified?
Yes.
What's the difference between vendor certification and software validation?
Vendor certification, like ISO 9001, is an audit of the company’s internal processes. Software validation is a separate exercise confirming a specific software version works as intended for a specific use, usually documented through IQ (installation qualification) and OQ (operational qualification) testing. A vendor can be certified without offering strong validation support, so it’s worth asking about both separately.
