Cloud vs on-premise QHSE software
Compare the actual service or installation offered, including its responsibilities and limitations. Hosting location alone does not establish a lower cost, stronger security, faster rollout or complete offline operation.

What vendors document about deployment
We checked the records of 212 QHSE, EHS and ESG software profiles through 2026-10-14. Where a profile has no statement, we found none; that does not mean the product lacks it. Every statement is the vendor's own and was not tested. The rules for each count are in our hosting and data location study. No product is named and nothing is ranked.
| The record states | Profiles | For either proposal, ask |
|---|---|---|
| States a delivery model73 cloud-hosted or SaaS with the tenancy not stated, 14 on-premises or self-hosted, 9 private or single-tenant, 9 installed on the customer's computers, 3 hybrid. 21 describe two or more kinds. | 85 of 212 | Read who runs each component, not the label. Write the split into the contract. |
| Describes a cloud-hosted service but names no provider, region or residency option42 profiles in all state a provider, a region, a residency statement or a choice of region. | 44 of 73 | Ask for the country or region of records, backups and attachments, and whether it can be fixed by contract. |
| Makes a backup statement2 state a service level and 2 give an uptime figure. | 9 of 212 | Ask who restores data after a failure, within what stated time, and when a restore was last tested. |
| Says what can be exported at exit11 give a deletion or retention rule. | 4 of 212 | Ask for the contents and format of an export, any fee, the deletion date and written confirmation. |
Most profiles that describe a cloud service do not say where the data is held, and few say anything about backup or exit. The label tells you little, which is why the questions on this page ask for the split of responsibilities in writing.
Compare complete proposals over the same period
Use your own licence, staffing, infrastructure and service quotes. Include migration, integrations, training, internal administration and exit work. Do not substitute a generic five-year market figure for a scoped proposal.
Agree rollout milestones around accepted data, permissions, recovery and representative user work. A vendor estimate should state dependencies; neither cloud nor local deployment establishes a fixed implementation duration.
A hypothetical three-year cost comparison
The figures are invented, in an unspecified currency, and are not market prices. They say nothing about any product or proposal, and the administration days for each column are assumptions chosen for the example, not findings. They show which lines to ask for, and how a single assumption can move the total.
| Cost line | Cloud proposal | On-premise proposal |
|---|---|---|
| Subscription (3 years at 30,000) | 90,000 | none quoted |
| Licence (one-off) | none quoted | 40,000 |
| Support and maintenance (3 years at 9,000) | none quoted | 27,000 |
| Servers and backup (3 years at 6,000) | none quoted | 18,000 |
| Set-up and configuration | 15,000 | 20,000 |
| Integration | 8,000 | 8,000 |
| Internal administration (60 and 90 days at 400 a day) | 24,000 | 36,000 |
| Exit work | 5,000 | 3,000 |
| Total over 3 years | 142,000 | 152,000 |
Three changes show how fragile a total is. If the cloud subscription rose from 30,000 to more than 33,333 a year (11.1% higher), the cloud total would pass the on-premise total. If the internal day rate were 600 instead of 400, both totals would rise, to 154,000 and 170,000, and the gap would widen from 10,000 to 16,000. If the on-premise administration took 60 days, like the cloud column, its total would fall to 140,000 and the order would reverse. Neither result says that one deployment is cheaper in general; it says the quote lines and the internal-time assumption matter more than the label.
Document the operating boundary
Ask who patches each component, restores data, changes access and responds to failed interfaces. Verify the certificate holder and scope of any security evidence; a hosting provider's certificate does not establish every application's controls. For hybrid designs, draw the data flow and identify each dependency.

Proposals that sit between the two labels
A proposal does not always fit one label. A vendor-managed installation in a named data centre, a private tenancy in a shared cloud and a cloud service linked to internal systems each blur the line between cloud and on-premise. Read the description of who runs which component, where records are stored, how a person signs in and what happens when a link fails, and ignore the label.
Ask the same questions of every arrangement and write the answers in one table, as above. If two proposals answer a question differently, that difference is the thing to cost, test or negotiate. If a question cannot be answered, record it as unresolved rather than assuming the answer you would like.
A short route to a deployment decision
Deployment is easier to settle once you know whether a rule fixes where the records must live and who would run the system. Three questions narrow it to a deployment to quote; none of the routes is better by default.
Text version of this decision tree
- Q1. Does a rule fix where the records must be kept? Read the actual wording before you answer.
- Yes: go to Q2 (Can your IT team patch, back up and restore it?).
- No, or not confirmed: go to Q3 (Must it reach systems that are not on the internet?).
- Q2. Can your IT team patch, back up and restore it? Include who answers when it fails.
- Yes: go to Outcome 1 (On-premise or private hosting).
- No: go to Outcome 2 (Vendor-managed in the named place).
- Outcome 1. On-premise or private hosting. Quote software, servers, backup and staff time together.
- Outcome 2. Vendor-managed in the named place. Ask which region and who restores data.
- Q3. Must it reach systems that are not on the internet? Think of plant or internal databases.
- Yes: go to Outcome 3 (Cloud with a defined link).
- No: go to Outcome 4 (Standard cloud service).
- Outcome 3. Cloud with a defined link. Draw the data flow and name each dependency.
- Outcome 4. Standard cloud service. Check responsibilities, export and exit terms.

Leaving a system: from notice to confirmed deletion
The steps below are a checklist of questions to settle with a supplier, not a description of what every supplier does. Ask about each of them before signing, while the terms are still open.
Text version of this diagram
- Step 1. Decide to leave. Owner: Customer. Reason, date, approver and the contract's notice terms. Then step 2.
- Step 2. Request the export. Owner: Customer. Formats, attachments and history requested in writing. Then step 3.
- Step 3. Deliver the export. Owner: Supplier. Delivery date, file list and any charge. Then step 4.
- Step 4. Reconcile the data. Owner: Customer. Record counts, and a sample opened in the new tool. Then step 5.
- Step 5. Run both systems for an overlap. Owner: Customer. Which system is the record, and until when. Then step 6.
- Step 6. Switch off and delete. Owner: Supplier. Deletion date, scope and written confirmation. Then step 7.
- Step 7. Keep what you decide to keep. Owner: Customer. Archive copy, its format and who can open it. End of the sequence.
Feedback loops
- From step 4 (Reconcile the data) back to step 2 (Request the export): Gaps found.
- From step 5 (Run both systems for an overlap) back to step 4 (Reconcile the data): Differences found.
Who processes your data in each model
Under Article 28 of the GDPR, which we read on EUR-Lex on 19 October 2026, processing carried out on behalf of a controller is governed by a contract. The contract has to say, among other things, that the processor acts only on the controller's documented instructions, that it may engage another processor only with the controller's written authorisation, and that at the controller's choice it deletes or returns all personal data at the end of the services. In a cloud service the vendor usually holds your records, so it is usually in that position. In an installation you run yourself, the vendor may still process personal data, for example when it gets remote access for support or runs the installation for you. Ask which of these applies to each proposal and get the answer in the contract.
For cloud services provided to customers in the EU, the Data Act (Regulation 2023/2854, applying from 12 September 2025) also sets switching terms: a maximum notice period of two months, a transitional period of no more than 30 calendar days and a data retrieval period of at least 30 calendar days. Its recitals name software as a service as one delivery model of data processing services. Whether it covers a given proposal is a question for your own legal adviser, and this is not legal advice. See the questions on exit costs and the RFP exit section. Sources: GDPR and Data Act on EUR-Lex.
Questions to ask a vendor
Put the same ten questions to every vendor and keep the answers in writing, with the date and the person who gave them.
- Which components do you run, which do we run, and where is that split written in the contract?
- Name the country or region where our records, backups and attachments are stored.
- Who restores data after a failure, within what stated time, and when was a restore last tested?
- How and when are updates released, how much notice is given and can we delay one?
- Which security certificate covers which part of the service, and is the holder you, your hosting provider or both?
- Show the mobile app with no signal: what is stored, what synchronises later and what fails?
- Which integrations are included, which need a separate licence and who maintains them after an update?
- What does an export contain: records, attachments, history and configuration? In which format?
- What notice, fees and support apply if we end the contract, and when are our data deleted?
- What changes in the quote if we add sites, users or storage?
Common mistakes when choosing
Reading the hosting label as a security answer
Where a system runs does not say who controls access, how changes are approved or what is logged. Ask for the controls in the actual proposal.
Comparing a subscription with a licence
A one-off licence and an annual subscription cover different things. Put every cost line over the same period before comparing.
Forgetting the internal time
Patching, backups and user administration can take staff time in either model. Write down who does them and for how many days.
Assuming local hosting means offline mobile work
A mobile app may still need a connection to the server. Test the disconnected workflow in the proposal.
Leaving exit to the end
Raise export formats and deletion terms before signing, and read them beside the price.
Treating a hybrid as the simple option
A hybrid adds a link between two systems, and that link can fail. Draw the data flow and name who fixes each part.
What this page cannot tell you
This page cannot say which deployment is cheaper or safer for your organisation. That depends on the quotes you obtain and the controls you can verify. It states no market share, price or implementation time, and the worked cost comparison uses invented figures in an unspecified currency. It does not cover laws on where records must be kept or on changing supplier, so ask your adviser which rules apply to your records and your contract.
The security and trial evidence study counts the researched profiles that mention a SOC 2 report or an ISO 27001 certificate. The study states that these are the vendors’ own statements and were not verified, so use the count to prepare questions for a vendor, not to judge its controls.
