Trex can close the books
because Trex is the books.

Many finance “copilots” are chatbots wrapped around an integration. Trex has the same database access, the same RBAC, and the same audit trail as your accountant.

What Trex actually does.

INTENT_PARSE

Understand

Map your request to a ledger operation. “Show March recurring expenses by department” → SQL on your books, not vibes.
$ “Show March recurring expenses…”
↳
GUIDANCE

Recommend

Suggest entries, accruals, mappings. Always with reasoning. Always pending your nod.
proposal · pending your nod
Provision — rent · March
REPLY_SYNTHESIS

Answer

Format the answer as a card, a table, a chart — not just markdown. Approvals are click-through.
GENERAL_CHAT

Explain

Why is this account here? What does “accrual” mean? Pulls from your COA, your audit log, your context.
$ what does “accrual” mean?
↳ recognised when incurred, not when cash moves — pulled from your COA + audit log

multi-provider llm router

Model orchestration, automated.
Override per session.

json invalid → retryrequest5 task classesroutercost-awaremistral · smallintent_parse · general_chatanthropic · sonnetguidance · reply_synthesisanthropic · opusbriefing
line weight = call share · illustrative
  • ▸Cost-aware routing. Cheap models for INTENT_PARSE, stronger models for REPLY_SYNTHESIS. You don’t pay Claude Opus rates to summarise an invoice.
  • ▸Per-session override. Force a specific provider for sensitive sessions (e.g. financial close on Claude only).
  • ▸Fallback chain. If primary fails JSON validation, we try secondary providers. Your accountant doesn’t see the retry.
  • ▸Your data stays yours. Requests go to Anthropic and Mistral under their no-train terms. We route, we don’t train.
rails · enforced in the ledger

The most useful thing about an in-ledger agent is that we know exactly where it can act. Here’s the rule sheet — as the agent sees it.

rails.policyENFORCED

Post anything to your books without your approval. Every Trex action is a proposal. You approve it, or it doesn’t happen.

Touch a hard-closed period. Blocked. Period reopen requires admin and audit entry.

Create a vendor and pay them in one session. Vendor creation is a separate approval gate. By design.

Send anything outside your tenant. Tenant-isolated. Trex cannot read data outside your schema.

Change the COA structure. Restricted to admin roles. Trex can suggest, not commit.

Train on your data. Pass-through to LLM providers under their no-train terms. We do not fine-tune on customer data.

$ trex import --from tally_export.xml

Watch Trex on your own books.

Bring a Tally XML export. We’ll spin up a tenant, import the data, and walk Trex through your month.
