# Startup Banking & Financial Setup

## Purpose

This recipe produces a fully operational startup financial infrastructure: an active business bank account with Treasury yield on idle cash, a configured accounting system with chart of accounts and connected bank feeds, a bookkeeping workflow (DIY or outsourced) with monthly reconciliation, and an expense management system with corporate cards and spend controls. The output is a startup that can receive revenue, pay vendors, track every dollar, and produce investor-ready financial statements from day one.

## Prerequisites
<!-- Agents: verify ALL prerequisites before executing. Missing prerequisites = failed execution. -->

- [ ] **EIN obtained** from IRS.gov — apply online at [IRS EIN Assistant](https://www.irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online) (instant, free)
- [ ] **Business legally formed** — LLC, C-Corp, or S-Corp filed with state Secretary of State
- [ ] **Operating Agreement or Bylaws** — signed and stored (required by most banks)
- [ ] **Founder government-issued ID** — driver's license or passport for bank KYC verification
- [ ] **Business address** — physical or registered agent address (PO Boxes not accepted by most banks)

## Constraints
<!-- Hard rules. Agents: enforce throughout execution. Violating these = broken output or legal risk. -->

- Never commingle personal and business funds. A single personal purchase on a business account can be used to pierce the corporate veil and eliminate liability protection. [src7]
- Use accrual-basis accounting if VC-backed or planning to raise. Cash-basis is acceptable only for bootstrapped businesses under $25M gross receipts. [src2]
- Reconcile books monthly at minimum. Quarterly reconciliation creates compounding errors that cost 3-5x more to fix and delays tax filing. [src2]
- Mercury and Ramp require a US-incorporated entity. Non-US founders need a US entity (Delaware C-Corp via Stripe Atlas or Firstbase) before proceeding. [src1]
- Keep at least 2 months of operating expenses in the checking account at all times. Sweep excess to Treasury or savings for yield.

## Tool Selection Decision

<!-- Agent selects the right tool path based on user inputs.
     Each path leads to a different execution flow below. -->

```
Which path?
├── Solo founder, bootstrapped, budget = free
│   └── PATH A: Mercury + Wave + DIY bookkeeping
├── Small team (2-5), pre-seed/seed, budget up to $100/mo
│   └── PATH B: Mercury + QBO Simple Start + Ramp + DIY bookkeeping
├── Funded startup (seed+), 5-20 employees, budget up to $500/mo
│   └── PATH C: Mercury + QBO Essentials + Ramp + Gusto + Pilot bookkeeping
└── Series A+, 20+ employees, no budget limit
    └── PATH D: Mercury + QBO Advanced or Xero + Ramp + Rippling + Pilot CFO
```

| Path | Tools | Cost/mo | Setup Time | Best For |
|------|-------|---------|------------|----------|
| A: Bootstrap Free | Mercury + Wave + DIY | $0 | 3-4 hours | Solo founders, pre-revenue |
| B: Lean Startup | Mercury + QBO + Ramp | $30-65 | 4-6 hours | Small teams, early revenue |
| C: Funded Startup | Mercury + QBO + Ramp + Gusto + Pilot | $350-700 | 6-8 hours | Seed-funded, hiring |
| D: Scale-Up | Mercury + QBO/Xero + Ramp + Rippling + Pilot CFO | $1,500-3,000 | 8-12 hours | Series A+, complex ops |

## Execution Flow

### Step 1: Open a Business Bank Account

**Duration**: 15-30 minutes to apply, 1-3 business days for approval
**Tool**: Mercury (recommended) or alternative

Open a free business checking account. Mercury is the default recommendation for startups because it charges zero fees, offers FDIC insurance up to $5M through sweep networks, and provides Treasury yield on idle cash. [src1]

```
Mercury Account Opening Checklist:
─────────────────────────────────────────
1. Go to mercury.com → "Open Account"
2. Select entity type (LLC / C-Corp / S-Corp)
3. Provide:
   ☐ EIN
   ☐ Business name (must match state filing exactly)
   ☐ Business address
   ☐ Formation date
   ☐ State of incorporation
   ☐ Founder name + SSN + date of birth
   ☐ Government-issued photo ID
4. Funding: $0 minimum — no initial deposit required
5. Wait 1-3 business days for approval

Post-Approval Setup:
   ☐ Order debit card
   ☐ Enable Mercury Treasury (sweep idle cash for yield)
   ☐ Set up ACH and wire transfer templates
   ☐ Add co-founders as authorized users (if applicable)
   ☐ Enable 2FA on all accounts
```

**Alternative paths by situation**:
- Need physical branches: Chase Business Complete ($15/mo, waived at $2,000 daily balance)
- Need high credit limits without personal guarantee: Brex (requires $50K+ in bank — note: Capital One acquiring Brex mid-2026) [src5]
- Need multi-entity support: Rho (free, designed for companies with complex structures)

**Verify**: Log into banking dashboard, confirm checking account is active, test a small ACH transfer ($1) to verify routing/account numbers work.
**If failed**: If declined, most common cause is entity name mismatch between bank application and state filing. Verify exact legal name with Secretary of State records and reapply.

### Step 2: Set Up Accounting Software

**Duration**: 1-2 hours
**Tool**: QuickBooks Online (recommended for most), Wave (free alternative), or Xero

Configure your accounting system with a startup-appropriate chart of accounts and connect your bank feed. [src2] [src3]

```
Accounting Software Selection:
─────────────────────────────────────────
Budget = $0/mo → Wave (free invoicing, expense tracking, basic reports)
Budget = $30-65/mo → QBO Simple Start or Essentials
Budget = $65-200/mo → QBO Plus (with inventory, project tracking)
Multi-currency needed → Xero (unlimited users, 1000+ integrations)

QBO Setup Checklist:
─────────────────────────────────────────
1. Sign up at quickbooks.intuit.com
2. Select industry → "Technology / Software" or closest match
3. Chart of Accounts — add these startup-specific accounts:
   ASSETS:
     ☐ Business Checking (Mercury)
     ☐ Business Savings / Treasury
     ☐ Accounts Receivable
   LIABILITIES:
     ☐ Accounts Payable
     ☐ Credit Card (Ramp)
     ☐ Accrued Expenses
     ☐ Convertible Notes (if applicable)
   EQUITY:
     ☐ Common Stock
     ☐ Additional Paid-in Capital (APIC)
     ☐ Retained Earnings
   REVENUE:
     ☐ Product Revenue
     ☐ Service Revenue
   EXPENSES:
     ☐ Payroll & Benefits
     ☐ Software & Subscriptions
     ☐ Cloud Infrastructure (AWS/GCP/Azure)
     ☐ Marketing & Advertising
     ☐ Legal & Professional Services
     ☐ Office & Co-working
     ☐ Travel & Meals
     ☐ R&D Expenses
4. Connect bank feed → Mercury checking + savings
5. Set fiscal year start (typically Jan 1 for calendar year)
6. Set accounting method to ACCRUAL (not cash)
7. Create invoice template with company logo and payment terms
8. Set up recurring expense categories and rules
```

**Wave Setup** (free tier path):
```
1. Sign up at waveapps.com
2. Add business → enter company details
3. Connect Mercury bank feed (via Plaid)
4. Set up income and expense categories
5. Create first invoice template
6. Note: Wave uses cash-basis by default
   — acceptable for bootstrapped startups
   — switch to QBO when pursuing VC funding
```

**Verify**: Bank feed shows recent transactions syncing automatically. Run a Profit & Loss report — it should show zero (or your opening transactions) without errors.
**If failed**: If bank feed connection fails, most common cause is multi-factor authentication blocking Plaid. Temporarily disable 2FA on bank, connect feed, then re-enable 2FA.

### Step 3: Establish Bookkeeping Workflow

**Duration**: 30-60 minutes to set up process, ongoing weekly/monthly
**Tool**: DIY (Path A/B) or outsourced service (Path C/D)

Decide between DIY bookkeeping and outsourced bookkeeping, then set up the recurring workflow. [src4] [src8]

```
Bookkeeping Decision:
─────────────────────────────────────────
DIY when:
  ☐ < 50 transactions/month
  ☐ Founder is comfortable with accounting basics
  ☐ Budget is constrained
  → Cost: $0 (your time: 2-4 hours/month)

Outsource when:
  ☐ > 50 transactions/month
  ☐ Revenue is coming in (need accurate accrual entries)
  ☐ Preparing for fundraising (investors want clean books)
  → Pilot: $599/mo (accrual, QBO-based, tax-ready)
  → Bench: $249/mo (cash-basis, simpler, less startup-specific)
  → Finta or Kruze: varies (startup-specialized)

DIY Weekly Bookkeeping Workflow (every Monday, 30 min):
─────────────────────────────────────────
1. Open QBO/Wave → review new bank transactions
2. Categorize each transaction to correct account
3. Upload/match receipts for expenses over $75
4. Flag anything unclear for end-of-month review
5. Check accounts receivable — follow up on overdue invoices

DIY Monthly Close (first week of each month, 1-2 hours):
─────────────────────────────────────────
1. Reconcile all bank accounts (checking + savings + credit cards)
2. Review uncategorized transactions — resolve all
3. Record any accrual entries (earned but unbilled revenue, prepaid expenses)
4. Run reports: P&L, Balance Sheet, Cash Flow Statement
5. Compare actuals to budget/forecast — note variances > 10%
6. File expense reports with receipts
7. Save monthly snapshot (PDF export of all three reports)
```

**Verify**: End-of-month bank reconciliation shows $0.00 difference between book balance and bank statement balance.
**If failed**: If reconciliation is off, most common cause is duplicate transactions from bank feed. Check for manual entries that were also auto-imported.

### Step 4: Set Up Expense Management

**Duration**: 30-60 minutes
**Tool**: Ramp (recommended) or alternative

Set up corporate cards with spend controls and automatic receipt capture. This eliminates expense reports and ensures every purchase syncs to your accounting system. [src5]

```
Ramp Setup (recommended for most startups):
─────────────────────────────────────────
Requirements: US-incorporated entity + $25K+ in business bank
1. Apply at ramp.com → connect Mercury bank account
2. Set company-wide spend policies:
   ☐ Max single transaction: $[amount]
   ☐ Monthly per-card limit: $[amount]
   ☐ Require receipt for purchases > $75
   ☐ Block specific merchant categories (gambling, personal)
3. Issue cards:
   ☐ Physical card for each founder
   ☐ Virtual cards for each recurring subscription (one per vendor)
   ☐ Virtual cards for ad spend (separate card per platform)
4. Connect Ramp → QBO/Xero for automatic sync
5. Enable receipt capture (mobile app + email forwarding)
6. Set up approval workflows:
   ☐ < $500: auto-approved
   ☐ $500-$2,000: manager approval
   ☐ > $2,000: founder approval

Benefits:
  → 1.5% cashback on all purchases
  → Automatic receipt matching
  → Real-time spend visibility
  → No personal guarantee required
```

**Alternative**: Mercury IO card (built into Mercury, simpler but fewer controls), Brex (higher credit limits, better for large ad spend)

**Verify**: Make a small test purchase ($5), confirm it appears in Ramp dashboard within minutes and syncs to accounting software within 24 hours.
**If failed**: If Ramp application is declined, most common cause is insufficient bank balance. Ensure $25K+ is in the connected account and reapply.

### Step 5: Configure Payroll (If Hiring)

**Duration**: 1-2 hours
**Tool**: Gusto (recommended for startups), Rippling (for tech-heavy teams)

If you have employees or plan to hire within 90 days, set up payroll now. If solo founder only, skip to Step 6. [src6]

```
Payroll Decision:
─────────────────────────────────────────
Solo founder, paying self → skip (take owner's draw from bank)
1-20 employees, US only → Gusto ($40/mo + $6/person)
  → Simple, transparent pricing
  → Automatic tax filing in all 50 states
  → Benefits enrollment built in
International or 20+ employees → Rippling ($8/person/mo + modules)
  → Global payroll in 130+ countries
  → IT device management built in
  → More complex but scales further

Gusto Setup:
─────────────────────────────────────────
1. Sign up at gusto.com → Simple plan ($40/mo + $6/ee)
2. Enter company details + EIN + state tax IDs
3. Connect Mercury checking account for payroll debits
4. Add employees:
   ☐ Legal name, SSN, address
   ☐ Salary or hourly rate
   ☐ W-4 withholding elections
   ☐ Direct deposit bank info
   ☐ Start date
5. Set pay schedule (biweekly recommended for startups)
6. Run first payroll → verify amounts, taxes, deductions
7. Connect Gusto → QBO for automatic journal entries
```

**Verify**: Run a test payroll cycle (or preview). Confirm federal, state, and local tax calculations are correct. Verify journal entries post to QBO correctly.
**If failed**: If state tax registration is missing, Gusto will flag it. Register for state withholding and unemployment tax accounts before the first payroll run.

### Step 6: Document Financial Stack and Access

**Duration**: 15-30 minutes

Create a single reference document that lists every financial tool, login, and process.

```
STARTUP FINANCIAL STACK REFERENCE

```

**Verify**: Every tool listed is accessible with current credentials. Bank feeds are syncing. Payroll (if applicable) is connected.
**If failed**: If any tool has lost bank connection, reconnect via Plaid. If credentials are missing, reset passwords before proceeding.

## Quality Benchmarks

| Quality Metric | Minimum Acceptable | Good | Excellent |
|---------------|-------------------|------|-----------|
| Bank feed sync | Manual import weekly | Auto-sync daily | Real-time sync |
| Transaction categorization | Monthly batch | Weekly review | Same-day with rules |
| Monthly close timing | By 15th of next month | By 10th | By 5th |
| Receipt capture rate | > 60% of expenses | > 85% | > 95% |
| Reconciliation accuracy | Within $100 | Within $10 | $0.00 difference |
| Financial report availability | Quarterly | Monthly | On-demand |

**If below minimum**: If monthly close is consistently after the 15th or reconciliation differences exceed $100, switch from DIY to outsourced bookkeeping (Pilot or Bench). The cost of errors compounds faster than the cost of the service.

## Error Handling

| Error | Likely Cause | Recovery Action |
|-------|-------------|----------------|
| Bank account application rejected | Entity name mismatch or incomplete formation docs | Verify legal name matches state filing exactly; provide complete Articles of Incorporation |
| Bank feed stops syncing | Plaid connection expired or bank 2FA changed | Disconnect and reconnect bank feed in accounting software; update Plaid credentials |
| Reconciliation difference growing monthly | Duplicate transactions from manual + auto import | Audit last 3 months for duplicates; delete manual entries that have auto-imported matches |
| Ramp application declined | Insufficient bank balance or entity too new | Ensure $25K+ in connected account; if entity is < 30 days old, wait and reapply |
| Payroll tax filing error | Missing state tax registration | Register for state withholding + unemployment accounts; Gusto provides state-by-state guidance |
| QBO subscription exceeds budget | Started on wrong plan or user count grew | Downgrade to Simple Start if < 1 user needs access; switch to Wave if pre-revenue |

## Cost Breakdown

| Component | Free Tier (Path A) | Lean (Path B) | Funded (Path C) | Scale (Path D) |

## Anti-Patterns

### Wrong: Using a personal bank account for business transactions
Founders who run early revenue through their personal checking account to "keep it simple" create a legal and tax disaster. Commingling funds can pierce your LLC/Corp liability protection, making founders personally liable for business debts. Separating accounts retroactively requires forensic bookkeeping at $150-300/hour. [src7]

### Correct: Open a dedicated business account before the first transaction
Even before revenue, use a business account for all startup expenses. Mercury takes 15 minutes to apply and 1-3 days to approve. There is no cost and no minimum balance.

### Wrong: Choosing accounting software based on current complexity
Founders pick Wave because it is free, then switch to QBO 6 months later when they raise funding — losing all historical categorizations, custom rules, and bank connections. Migration costs 8-20 hours and introduces data integrity risk. [src3]

### Correct: Choose based on 12-month trajectory
If you plan to raise venture capital within 12 months, start with QBO. Investors and CPAs expect QBO. The $30/month cost is trivial compared to the migration cost later. Only use Wave if you are bootstrapping long-term.

### Wrong: Skipping expense management and using personal cards with reimbursements
Reimbursement workflows break at 3+ people, create tax complications, and make spend invisible until the credit card statement arrives. By then it is too late to control.

### Correct: Issue corporate cards from day one
Ramp and Mercury IO cards are free with automatic receipt capture and accounting sync. Every dollar is tracked in real time with zero manual expense reports. [src5]

### Wrong: Delaying payroll setup until the first hire starts
Payroll requires state tax registrations that take 2-4 weeks to process. Starting an employee before payroll is configured means either paying them late (illegal in most states) or processing manually (error-prone). [src6]

### Correct: Set up payroll 30 days before first hire date
Register for state withholding and unemployment accounts immediately after deciding to hire. Configure Gusto or Rippling so the first payroll run is seamless.

## When This Matters

Use this recipe when a startup is legally formed and needs to build operational financial infrastructure. It produces configured, connected financial tools — not a strategy document. The output enables the startup to receive payments, pay vendors, track expenses, and produce financial statements that investors and accountants can work with. This should run after entity formation and before the first business transaction.
