If you report as one legal entity, being single-entity removes exactly two things from an IFRS S2 first cycle: consolidating several entities, and eliminating the overlap between them. It removes nothing else. You still disclose against governance, strategy, risk management and metrics; every figure still needs the document it came from; and an assurance provider will still ask who approved it and when. So the question is not whether you need a platform. It is whether one spreadsheet and one folder can still answer those questions in eighteen months.

Key points
- Single-entity reporting removes consolidation and intercompany elimination, and nothing else.
- IFRS S2 applies to annual reporting periods beginning on or after 1 January 2024, with earlier application permitted if IFRS S1 is applied too.
- The first-year transition reliefs reduce the scope of what you disclose. They do not reduce the standard of evidence behind what you do disclose.
- A spreadsheet can carry a first cycle. It struggles at the second, when someone asks how last year’s figure was reached.
- We publish our prices, and one of our controls can be tested by a stranger without an account.
What being one entity actually drops
Most guidance for smaller reporters is written as though scale is the only variable, so the advice reduces to “you have less to do”. That is true of the arithmetic and untrue of the controls.
Consolidation is genuinely hard, and a single entity is spared it. There is no mapping of subsidiary figures into a group total, no decision about which entities sit inside the reporting boundary, and no intercompany energy or travel to strip out so the same tonne is not counted twice. If you are one company with one set of books, that work does not exist for you.
Everything else survives the reduction in scale. IFRS S2 asks for disclosures across four areas — governance, strategy, risk management, and metrics and targets — and the standard does not soften them for smaller reporters. A one-site manufacturer discloses how climate risk is governed, in the same terms as a company forty times its size. The difference is the length of the answer, not whether one is owed.
What you still have to produce
Underneath the disclosure sits the part that catches first-time reporters: for each figure you publish, someone will eventually ask where it came from. Not in an abstract sense. Specifically: which invoice, which meter reading, which emission factor and which version of it, who checked the arithmetic, and who signed it off.
In a group, that trail is a project because it crosses entities. In a single entity it is smaller, but it is the same trail, and it has one characteristic that makes it awkward for spreadsheets: it has to still be true later. A figure you can explain today is not the same as a figure you can evidence in eighteen months, after the person who prepared it has changed roles and the source workbook has been through nine saves.
This is the part we built the product around, and it is also the part we would encourage you to test before believing anyone, including us. Our activity log is append-only at the database level rather than by convention, and you can try to alter a record on a live demonstration tenant and read the error the database returns. No account, no email address. If a vendor tells you their audit trail is immutable, that is the level of proof worth asking for.
What the first year lets you defer
IFRS S2 is effective for annual reporting periods beginning on or after 1 January 2024, and earlier application is permitted as long as IFRS S1 is applied as well, according to the IFRS Foundation’s standards navigator.
The transition reliefs matter more to a small reporter than to a large one, because they change how much has to exist in year one. In summary, they permit climate-only reporting, allow Scope 3 emissions to be omitted, remove the comparative information requirement, allow the sustainability disclosures to be published after the financial statements, and permit continued use of an existing greenhouse gas measurement method. We set out each relief against its paragraph, and where the deferral ends, in a separate piece on the transition reliefs.
The trap is reading them as a reduction in rigour. They reduce scope. Nothing in them reduces the standard of evidence behind the figures you do publish, and three of them run out after the comparatives, which means the capability has to exist by year two regardless. A first cycle built to survive only the first cycle is a decision to do the work twice.
Can you do it in a spreadsheet?
Honestly: for a genuine first cycle at a single entity, often yes. If one person collects the data, one person reviews it, one person approves it, and all three are in the same room, a workbook and a well-named folder can produce a defensible first report. Anyone who tells you a one-site company categorically cannot report without buying something is selling.
The place it stops working is specific enough to describe. A spreadsheet records the current value of a cell, not the history of how it got there. When the reviewer changes 412 to 418, the workbook keeps 418. It does not keep who changed it, when, why, or what the supporting document said at the time. You can add that discipline manually with a change log and a naming convention, and some teams do it well, but you are then maintaining a control by hand at exactly the moment you are also learning a new standard.
We have written separately about where the calculation ends and the control begins. The short version: use the spreadsheet for the arithmetic if you like it, and put the control somewhere the arithmetic cannot quietly overwrite.
Four things to check in any tool
If you do evaluate software as a single entity, four questions separate tools quickly, and none of them is about feature count.
Does it hold the document next to the figure? Not a link to a shared drive that may be reorganised, but the file itself, attached to the number it supports. Ask what happens to that attachment when the source folder is moved.
Can the log be edited by anyone, including the vendor? Ask specifically whether the trail is append-only in the database or enforced in the application. The second can be bypassed by anyone with database access, which includes the vendor’s own staff.
What comes out at the end? An assurance provider will ask for a package, not a login. Find out what the export contains and whether it can be produced without the vendor’s help.
What does it cost, and can you find that out without a call? A per-user price is a poor fit for a single entity where one or two people do everything, and a per-tonne price prices you on emissions volume rather than on how hard the disclosure is to evidence.
What this product does not do
Auditably is an IFRS S2 disclosure-controls system. It holds the 33 disclosure requirements of the standard as tracked items, attaches evidence to each figure and hashes it on upload, records review and approval against named users in the roles of preparer, reviewer and approver, writes every change to an append-only log, and exports an auditor pack containing the disclosures, the activity log and the evidence files with a manifest of checksums. Practitioner is $399 a month or $3,990 a year and covers one reporting cycle for one entity, which is the configuration this article describes. All paid plans carry a 14-day cancellation right through Paddle.
What it does not do is worth stating plainly, because the limits decide whether it suits you:
- It does not calculate your emissions. It is not a carbon accounting engine, and it will not turn meter readings into a Scope 1 figure. Bring the number and the working.
- It does not file anything. Where your regulator requires a tagged submission, that is a separate step.
- It does not reconcile climate figures to the financial statements.
- It does not replace an adviser on judgement calls such as materiality or scenario selection.
- We are at design-partner stage and have no customers to point at. There are no logos on this site because there is nothing honest to put there.
The full boundary, including what is enforced in the software today against what is currently only documented, is set out on the coverage page.

Do I need software for IFRS S2 if I am only one entity?
Not necessarily in the first year. If you have one site, one preparer and one approver, a spreadsheet plus a disciplined folder structure can carry a first cycle. Software earns its place when more than one person touches a figure, when the same figure is reported again the following year, or when an assurance provider will ask who approved a number and on what evidence.
What does IFRS S2 reporting software cost for a small company?
Most vendors do not publish a price, so a comparison usually starts with a form. We publish both tiers: Practitioner at $399 a month or $3,990 a year for one reporting cycle at one entity, and Pro at $799 a month or $7,990 a year for multiple entities and cycles, up to five users, and disclosure drafting on your own API key. Prices are billed in USD and carry a 14-day cancellation right through Paddle.
What can a single entity defer in its first cycle?
The transition reliefs permit climate-only reporting, allow Scope 3 emissions to be omitted, remove the comparative information requirement, permit publication of the sustainability disclosures after the financial statements, and permit continued use of an existing greenhouse gas measurement method. They apply to the first annual reporting period, and three extend into the second year for comparatives only.
Does being a single entity make IFRS S2 easier?
It removes consolidation and intercompany elimination. It does not remove anything else. The four disclosure areas apply the same way, every figure still needs the document it came from, and an assurance provider will still ask who approved it.
Do I need assurance in my first year?
That is set by your jurisdiction rather than by IFRS S2 itself. ISSA 5000, the global sustainability assurance standard, applies to sustainability information for periods beginning on or after 15 December 2026, with early application permitted, per the IAASB. Whether assurance is mandatory for you earlier than that is a question for your regulator or exchange.
How we sourced this
The effective date and the early-application condition are quoted from the IFRS Foundation’s standards navigator page for IFRS S2, linked above. The ISSA 5000 effective date is from the IAASB’s own publication page for the standard. The transition reliefs are summarised here and set out against their paragraph references, with sources, in our separate article on them; the IFRS Standards themselves sit behind the Foundation’s registration wall, so we cite the Foundation’s public explanatory material rather than paraphrase the text from memory.
