If you’ve ever sat in a reporting close and watched a 10-K bounce between four different tools before it’s ready to file, you already know the problem this article is about. Someone pulls numbers from the ERP. Someone else drops them into Excel. A third person rebuilds the whole thing in Word so legal can mark it up. And then, at the very last stage, someone has to convert all of that into a format the SEC will actually accept, tag it, validate it, and hope nothing breaks on submission day.
Every handoff in that chain is a place where errors creep in, deadlines slip, and someone ends up working late the night before a filing is due.
This is the exact problem IRIS CARBON is built to solve, and it’s worth walking through the full workflow step by step, both to understand what a modern EDGAR filing process actually looks like and to see how a single platform can carry a filing from raw data all the way to SEC submission without the usual game of telephone between tools.
Why Fragmented EDGAR Filing Processes Break Down
When finance, legal, and XBRL teams each work from their own files, three problems show up every quarter:
| Version Control Gaps: A late change in the general ledger has to be re-keyed into Excel, Word, and the XBRL file separately. Miss one, and the visible text stops matching the tagged data. | Formatting Loss: Converting Word or PDF drafts into a submission-ready filing tends to mangle tables and headers, forcing teams to rebuild formatting they thought was finished. | Broken Audit Trails: When legal reviews a PDF while XBRL specialists work from a separate mapping sheet, it becomes hard to trace who changed a disclosure, or why. |
Bringing everything onto one system removes most of that friction at the source.
From ERP to SEC: The Complete End-to-End EDGAR Filing & iXBRL Workflow Guide
Here’s what actually happens at each step of an EDGAR filing, where it tends to break down, and how IRIS CARBON closes those gaps by keeping the whole process on one platform.
Step 1: Creating a Roll Forward of Prior Period Data with Embedded XBRL
The Step: No filing starts from a blank page. Teams roll forward the prior period’s report structure, and the XBRL tags attached to that report need to carry forward with it, not get rebuilt from scratch each cycle.
The Problem: In a disconnected setup, the prior period’s XBRL lives in a separate file from the prior narrative. That means teams spend the first days of every close recreating tag mappings and document structures that were already finished last quarter, work that should already be settled.
How IRIS CARBON Helps: Every new period starts from the prior filing with its XBRL already embedded in the document itself. Structures, taxonomy elements, and tag mappings roll forward automatically alongside the narrative, so teams open the quarter with a completed foundation instead of a blank template and a stack of last quarter’s files to reconstruct.
Step 2: Pulling Together the Source Data
The Step: A filing starts with numbers from the general ledger and ERP (SAP, Oracle NetSuite, Workday), plus subsidiary schedules, ESG metrics, and prior-period XBRL facts that need to roll forward consistently.
The Problem: These streams live in different systems, owned by different teams. Someone has to manually re-key ERP exports into a reporting template, and that’s exactly where transposition errors, broken roll-forwards, and ties that quietly stop balancing tend to creep in.
How IRIS CARBON Helps: Because the whole platform lives inside the Word and Excel environment teams already use every day as part of Office 365, data flows in through structured templates and direct system imports without asking anyone to leave the tools they’re already comfortable in. Prior-year structures and taxonomy choices carry forward automatically, so teams start from a single source of truth instead of stitching one together every quarter, no copy-paste required, and no separate system to learn.
Step 3: Drafting and Reviewing the Report
The Step: Legal, accounting, compliance, and internal audit all need to draft, mark up, and sign off on the same narrative before it’s final.
The Problem: In a disconnected setup, this means dozens of Word files circulating over email, section-level edits stepping on each other, and no clear record of who changed what, or why, once three people have touched the same footnote.
How IRIS CARBON Helps: Everyone works inside the same connected document, in the familiar Word and Excel environments they already use. Section-level locking stops two people from editing the same footnote at once, built-in commenting replaces the email chain, and every edit is logged down to the sentence level, giving you a full audit trail instead of a reconstruction job.
And rather than writing narratives entirely from scratch each quarter, IRIS CARBON embeds specialized AI tools directly into the authoring workspace to accelerate draft creation and executive review:
- AI Content Generation: Automatically drafts content that expands team bandwidth by eliminating repetitive roll-forward drafting during high-stress close windows.
- AI Summarization: Converts dense financial tables and lengthy footnote disclosures into clear executive summaries, allowing controllers and review leads to digest complex changes quickly during tight close windows.

Step 4: Edgarization, Turning the Draft into a Submission-Ready Filing
The Step: Once the narrative is final, it has to be transformed into the exact format the SEC will accept for submission, a process filers commonly call Edgarization.
The Problem: This step is far more specialized than it looks. Getting a document from a Word or PDF draft into a submission-ready filing requires a working knowledge of SEC formatting requirements that most internal teams simply don’t encounter often enough to master. That’s exactly why so many companies end up outsourcing this step to a vendor at the last minute.
How IRIS CARBON Helps: The platform Edgarizes the document continuously as it’s being built, drawing on a team of filing specialists who handle this work every day rather than a generic export function. Formatting stays submission-ready throughout drafting, so there’s no separate outsourced step, no vendor handoff, and no last-minute scramble to fix layouts before the deadline.
Step 5: Tagging the Data in iXBRL
The Step: Every financial fact needs a tag mapped to a standard taxonomy element (US-GAAP or IFRS), with custom extensions used only where the standard taxonomy falls short and those extensions still need to link back to the nearest standard element.
The Problem: Tagging every fact, footnote, and table cell across a full 10-K by hand is slow and easy to get wrong, and a mismatch between the visible numbers and the underlying tags is one of the most common reasons filers get an SEC comment letter.
How IRIS CARBON Helps: Through the IRIS CARBON add-in, the document a client is working on already carries its tags behind the scenes as it’s being drafted, so there’s no separate tagging phase to wait for once the narrative is done. That tagging is expert-assisted, it’s carried out by IRIS CARBON’s XBRL specialists, who bring two decades of hands-on tagging experience to every filing, reviewing and applying each tag by hand. The system also checks that the human-readable numbers in the document match the tagged values, catching mismatches before they ever reach the SEC.
Step 6: Validating Before Submission
The Step: Filings need to clear calculation checks, taxonomy and syntax rules, and Data Quality Committee (DQC) checks before they’re ready to go out.
The Problem: When validation happens late, or with a different tool than the one the SEC actually uses, errors surface after the fact often forcing a scramble the night before the deadline.
How IRIS CARBON Helps: The platform runs the same Arelle-based validation engine the SEC uses internally, alongside DQC rules, so teams see the exact error code, line, and tag rule that EDGAR would flag before they ever hit submit.
Step 7: Submitting to EDGAR
The Step: The finished package needs to reach the SEC and come back with an official accession number and acceptance confirmation.
The Problem: Traditionally, this means handing the file to a filing agent, waiting in a queue, and hoping nothing goes wrong on submission night, an extra handoff, and an extra place for last-minute errors to creep in.
How IRIS CARBON Helps: Teams submit directly from the platform using their own SEC credentials. A test filing runs first to confirm formatting and structure; once that clears, the live filing goes out, and EDGAR’s timestamp and acceptance notice come back into the same system. The platform also supports EDGAR Next’s move to login.gov-based accounts and API-token authorization, so permissions stay current as SEC requirements change.
Putting the Workflow Together: A Single Filing, Start to Finish
Disconnected tools turn SEC reporting into a long chain of manual handoffs. Bringing the pipeline onto a single platform ties data ingestion, authoring, tagging, validation, and submission into one continuous workflow instead:
Comparison Table
| Reporting Stage | Disconnected / Agency Model | Native IRIS CARBON Platform |
| 1. Prior-Period Roll Forward | XBRL and narrative structure rebuilt from separate files each cycle. | Prior filing’s structure and XBRL carry forward automatically, already embedded in the document. |
| 2. Data Ingestion | Manual copy-pasting from ERP/Excel exports. | Centralized repository inside Office 365, with structured templates and direct system imports. |
| 3. Narrative Authoring | Manual drafting and high-friction roll-forwards. | AI-assisted roll-forwards that maximize team bandwidth. |
| 4. Formatting & Edgarization | Third-party conversion, broken layouts, external fees. | Continuous, native Edgarization handled by in-house filing specialists, no vendor handoff. |
| 5. Data Tagging | Separate software or outsourced tagging bureau. | Tags embedded in the document from the start, applied by specialists with two decades of tagging experience. |
| 6. SEC Engine Validation | Errors caught late, triggering close scrambles. | Real-time validation via native SEC Arelle engine and DQC rules. |
| 7. EDGAR Submission | Agent handoffs, queue delays, shared passwords. | Direct EDGAR transmission with EDGAR Next API governance. |
Running these stages on one platform gets reporting teams up to a 40% reduction in preparation timelines, while removing most of the data inconsistencies that show up across disclosures when the work is spread across disconnected tools.
The Net Effect
Keeping data, drafting, tagging, validation, and submission on one platform means the same numbers, the same document, and the same audit trail carry through the entire filing, instead of being rebuilt at every handoff. That’s the main reason teams that consolidate this way cut filing prep time significantly compared to the disconnected, multi-vendor approach.
