01What it costs
Checked Aug 10, 2026 · source: expensify.com.
| Plan | Monthly | Billed yearly | What you get |
|---|---|---|---|
| Personal | Free | Free | Unlimited SmartScans; unlimited manual expenses and mileage; CSV export; 0 workspace categories, tags, accounting integrations, or Expensify Card controls |
| Collect, pay per use | $5 | — | $5 per unique member used in a month; expense reports, reimbursements, cards, travel, invoicing, and accounting sync |
| Control, pay per use | $36 | — | $36 per active member in a month; advanced approvals, compliance, controls, and accounting features |
| Control, annual commitment | $36 | $18/mo | $18 per committed member/month; active members above the commitment are $36 each |
Hidden costs: A 12-month commitment can be increased but not decreased during the term; active users over the committed count cost $36 each. The maximum 50% card discount depends on the share of approved USD expenses put on the Expensify Card. Taxes may be added. Legacy subscriptions predating April 1, 2025 can use different $10/$5 structures.
02Could AI build it for you?
The core job: Build a private expense management ledger that imports user-supplied CSV files, categorizes entries, reconciles balances, and exports reports.
What a working version needs:
- Node.js 22
- SQLite
- CSV exports from the user's own accounts
- Explicit README warning that this is a consolation build, not a production replacement
Credibility row: Expensify survives for a structural reason, not because its interface is difficult to copy.
03What you'd give up
- tax and accounting rule updates
- audited security and recovery
- multi-user controls and accountant workflows
- bank, payment, tax, and reconciliation integrations
- live bank feeds and payment rails
Expensify: People pay because errors touch real money. Bank connections, reconciliation, tax changes, evidence, security, and support are the product.
