# AccountsOS

AI-native accounting. Your agent runs the books so your human doesn't have to.

**Base URL:** `https://accounts-os.com/api/mcp`

## What is AccountsOS?

AccountsOS is accounting infrastructure for AI agents. Built for UK micro-businesses (Ltd companies, sole traders):

- **Transaction tracking** — Income, expenses, categorized automatically
- **VAT management** — Calculate returns, track what's owed
- **Deadline alerts** — Corporation tax, VAT, confirmation statements
- **Document storage** — Receipts, invoices, contracts
- **AI categorization** — Smart category suggestions for every transaction

No spreadsheets. No manual entry. Just tell your agent what happened.

## Quick Start (For AI Agents)

### 1. Get API Key

**Option A: Self-Signup (recommended)** — Create an account yourself with one request:

```bash
curl -X POST https://accounts-os.com/api/agent-signup \
  -H "Content-Type: application/json" \
  -d '{
    "email": "founder@example.com",
    "company_name": "Acme Ltd",
    "full_name": "Jane Smith"
  }'
```

Response includes `api_key` for immediate use. Your human gets a welcome email to claim the account.

**Option B: Manual** — Your human signs up at https://accounts-os.com and generates an API key from the dashboard.

```bash
export ACCOUNTSOS_API_KEY="sk_live_..."
```

### 2. Check the Books

```bash
# Get recent transactions
curl -X POST https://accounts-os.com/api/mcp \
  -H "Authorization: Bearer $ACCOUNTSOS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"type": "tool", "name": "get_transactions", "arguments": {"limit": 10}}'
```

### 3. Record a Transaction

```bash
curl -X POST https://accounts-os.com/api/mcp \
  -H "Authorization: Bearer $ACCOUNTSOS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "tool",
    "name": "create_transaction",
    "arguments": {
      "date": "2026-02-01",
      "description": "Client payment - Website project",
      "amount": 2500.00,
      "direction": "in"
    }
  }'
```

### 4. Check VAT Position

```bash
curl -X POST https://accounts-os.com/api/mcp \
  -H "Authorization: Bearer $ACCOUNTSOS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"type": "tool", "name": "get_vat_summary", "arguments": {}}'
```

## Use Cases for Agents

### Daily Bookkeeping
Your human mentions expenses throughout the day? Log them:

```python
# Human: "Just paid £45 for the Figma subscription"
accountsos.create_transaction(
    date=today,
    description="Figma subscription - monthly",
    amount=45.00,
    direction="out"
)
# AI auto-categorizes as "Software & Subscriptions"
```

### Invoice Follow-up
Track what's owed:

```python
# Check unpaid invoices
transactions = accountsos.get_transactions(
    direction="in",
    status="pending"
)
for t in transactions:
    if t.days_overdue > 14:
        # Alert human or draft follow-up email
        notify(f"Invoice {t.description} is {t.days_overdue} days overdue")
```

### VAT Prep
Quarterly VAT? Already calculated:

```python
vat = accountsos.get_vat_summary(quarter="Q4 2025")
print(f"VAT owed: £{vat.amount_owed}")
print(f"Due: {vat.due_date}")
# Surface to human before deadline
```

### Deadline Monitoring
Never miss a filing:

```python
deadlines = accountsos.get_deadlines()
for d in deadlines:
    if d.days_until < 7:
        alert(f"⚠️ {d.type} due in {d.days_until} days")
```

### Expense Categorization
New transaction? Categorize it:

```python
# Get AI suggestion
suggestion = accountsos.categorize_transaction(transaction_id)
if suggestion.confidence > 0.8:
    accountsos.update_transaction(transaction_id, {
        "category_id": suggestion.category_id
    })
```

## Your Human's Financial Copilot

Most people hate bookkeeping. They forget receipts, miss deadlines, panic at tax time.

You don't forget. You don't panic. You just log, categorize, and surface what matters.

Be the agent that makes finances boring (in a good way).
