Build or Buy AI for Your Close?
Anyone can build workpaper 1. Only Truewind can build workpaper 12.

Build with Claude or Gemini when the work is summarizing, analysis or reporting. Buy when the output posts to your general ledger every month. General-purpose AI can give a different answer each time it runs. Truewind pairs AI with deterministic logic, so the same source data produces the same journal entries every month, with an SOP, audit-ready logs and a workpaper that rolls forward from the month before.
Can you build month-end close workflows in Claude or Gemini?
Yes, for the first one. Frontier models are good at reading statements and explaining what they find. The cost shows up in the months after: the output can change between runs, a new statement format means another fix, and someone has to own the prompts, the posting step, security and access every time the models change.
Why does the same prompt give a different answer?
Frontier models are probabilistic: the same prompt can produce different output on each run. Truewind alternates AI steps with deterministic logic steps. AI reads and explains. Logic does the accounting. The result is the same answer every month, with your team reviewing only the exceptions.
What does it take to run it every month?
You built it for three accounts. Here's what it takes to run it for 200.
| Feature | Build in Claude or Gemini | Truewind |
|---|---|---|
| Same answer every month | Output can vary between runs | Same source data, same entries: AI reads and explains, logic does the accounting |
| Month 2 and after | Re-run and re-check the prompt each month | Each workpaper rolls forward from the last |
| Process documentation | Lives in the prompt or in someone's head | SOP generated from the work |
| Posting to the GL | Export, reformat and import, or build and maintain an integration | Drafted journal entries post to Sage Intacct or QuickBooks Online after review |
| Audit trail | Whatever your team builds | Audit-ready logs for every posting decision |
| Security | Your team vets the tools, access and data handling | SOC 2 Type 2, role-based access, encryption in transit and at rest |
| Maintenance | Your team, whenever models or source formats change | Truewind, so upkeep doesn't fall on your team |
| Scaling to more entities or clients | Rebuild or re-prompt for each one | One SOP reused across entities and clients |

When does building make sense?
Build for work that reads and reports: summarizing documents, answering one-off questions, analysis, reporting and cash flow forecasting. Buy for work that writes to your systems: recurring reconciliations, journal entries posted to the GL, multi-entity closes and anything your auditor will review.
How does Truewind post to the general ledger?
Truewind connects directly to Sage Intacct and QuickBooks Online and posts drafted journal entries after your team reviews them; it also supports Intuit Enterprise Suite and NetSuite. On Sage Intacct, the chart of accounts, entity structure and bank feeds sync automatically, and Sage stays the system of record.
What happens when a source file changes?
The agent asks clarifying questions instead of guessing, and the answer goes into the SOP. An SOP built for one entity or client can be reused across others, so the work you teach Truewind once carries forward.
Is my financial data secure?
Truewind is SOC 2 Type 2 certified. Data is encrypted in transit and at rest, access is restricted by user role, and people review AI outputs before anything is posted where a workflow requires it.

Frequently asked questions
- Can I use Claude or Gemini for my month-end close?
- You can use them to read statements, summarize activity and draft analysis. For recurring reconciliations and journal entries that post to your GL, you need the same answer every month, an audit trail and a maintained connection to your ledger. Truewind provides those on top of the AI.
- What's the difference between probabilistic and deterministic AI in accounting?
- Probabilistic AI can return a different answer each time it runs on the same input. Deterministic logic returns the same answer every time. Truewind uses AI to read and explain source documents and deterministic logic to do the accounting, so month 12 matches month 1.
- Who maintains the workflow after it's built?
- Truewind, so the burden doesn't fall on your team. Each month's workpaper rolls forward from the last. With an in-house build, your team owns maintenance whenever models, source formats or your chart of accounts change.
- Do I have to switch accounting systems?
- No. Truewind works on top of Sage Intacct, QuickBooks Online, Intuit Enterprise Suite and NetSuite. Your ledger stays the system of record and nothing migrates.
