  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by openaccountant on GitHub. Read the source before you install it.

Installation

Install the Multi Entity AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/openaccountant/skills/tree/main/business/multi-entity
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/openaccountant/skills.git /tmp/skills
mkdir -p .claude/skills
cp -r /tmp/skills/business/multi-entity .claude/skills/multi-entity
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Multi Entity in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Multi Entity on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Multi Entity is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Multi-Entity Financial Management

Overview

Track and report on finances across multiple businesses, LLCs, or legal entities from a single view. Prevents commingling, generates per-entity reports, and provides a consolidated overview.

Wilson Tools Used

  • transaction_search — query transactions filtered by entity (using account, tag, or category prefix) to isolate each business
  • spending_summary — generate per-entity spending summaries for comparison
  • export_transactions — export entity-specific transaction sets for accountants or tax filing

Workflow

  1. Ask the user to define their entities and how they are separated (separate bank accounts, category prefixes, tags, or description patterns).
  2. For each entity, use transaction_search with the appropriate filter:
    • By account: search transactions from the specific bank account
    • By tag/prefix: search for transactions tagged or prefixed with the entity name (e.g., "LLC1:" or "rental:")
  3. Use spending_summary for each entity over the same period.
  4. Generate per-entity P&L summaries plus a consolidated view:
MULTI-ENTITY SUMMARY — [Period]
═══════════════════════════════════════════════════════
                    Entity A    Entity B    Consolidated
                    (Consulting) (SaaS)
───────────────────────────────────────────────────────
Revenue              $45,000     $22,000       $67,000
Expenses            ($28,000)   ($18,000)     ($46,000)
Net Income           $17,000      $4,000       $21,000
Net Margin             37.8%       18.2%         31.3%

Cash Balance         $32,000     $14,000       $46,000
───────────────────────────────────────────────────────
Inter-Entity Transfers: $2,500 (A → B)
═══════════════════════════════════════════════════════
  1. Flag any inter-entity transfers (payments between your own accounts/entities) and exclude them from revenue and expense totals to avoid double-counting.
  2. Use export_transactions to create separate CSV files per entity for tax preparation.
  3. Alert on commingling: flag personal expenses in business accounts or business expenses in personal accounts.

Without Wilson

  1. If each entity has a separate bank account (recommended), export each account's transactions as a separate CSV file.
  2. If entities share a bank account (not recommended but common), export all transactions and add an "Entity" column. Tag each transaction manually.
  3. Create separate spreadsheet tabs per entity. For each: pivot by category, sum income and expenses.
  4. For the consolidated view, create a summary tab that references each entity tab: =EntityA!TotalRevenue + EntityB!TotalRevenue.
  5. Track inter-entity transfers: search for transfers between your accounts. Mark these as "Transfer" category and exclude from income/expense totals.
  6. For tax filing, each entity files separately. LLCs file Schedule C (single-member) or Form 1065 (multi-member). S-corps file Form 1120-S. Keep transaction exports separated by EIN.
  7. Use separate QuickBooks files or Xero organizations per entity. QBO allows up to 25 companies per subscription.

Important Notes

  • Separate bank accounts per entity is strongly recommended. Commingling funds can pierce the corporate veil and remove liability protection.
  • Inter-entity transactions (loans, payments, shared expenses) must be tracked carefully. They are not income or expenses — they are transfers.
  • If one entity pays a shared expense (e.g., office rent), split it proportionally and record an inter-entity receivable/payable.
  • Each entity should have its own EIN. Do not use one EIN for multiple entities.
  • Consult a CPA for multi-entity tax strategy. Entity structure (LLC, S-corp, C-corp) significantly affects tax liability.

Frequently asked questions

What does the Multi Entity AI skill do?

Manage finances across multiple businesses or legal entities.

Why use Multi Entity on TypingMind?

Because you install it once and use it with any model. Multi Entity is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Multi Entity in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/openaccountant/skills/tree/main/business/multi-entity. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Multi Entity?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Multi Entity?

As many as you like. As long as a model supports skills, you can use Multi Entity with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Multi Entity AI skill free?

Yes. It is published on GitHub by openaccountant under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
