Pros & Cons
Brex
Pros
- The Essentials tier is free and includes cards, bill pay, reimbursements, travel booking, API access and accounting integrations.
- Card limits are underwritten on cash balance and revenue rather than a founder's personal guarantee, which helps startups without a credit history.
- Direct ERP syncs cover NetSuite, QuickBooks Online, Xero, Sage Intacct, Business Central and newer AI-native ERPs such as Rillet and Campfire, and a two-way Accounting API launched in January 2026.
- Brex holds SOC 1 Type II and SOC 2 Type II attestations, is PCI-DSS compliant and supports SAML or OIDC single sign-on.
- Brex releases updates often. The September 2026 release alone added more than 30 features, including passkeys, p-card policy rules and access to Brex data from ChatGPT, Claude and Slack.
- Pricing is published at 12 USD per user per month for Premium, and G2 reviewers rate the product highly, at about 4.8 out of 5.
Cons
- Brex has a history of abrupt account closures and eligibility changes, and it left the small-business market in 2022.
- Credit limits move with the company's cash balance, which some reviewers find unpredictable.
- Card purchases that need currency conversion carry an FX markup of up to 3 percent, built into the exchange rate.
- It is not a general ledger. Bookkeeping and financial statements still need a separate ERP or accounting system.
- Some support and setup experiences are poor, including a clunky HRIS integration setup reported on Gartner Peer Insights.
- The Capital One acquisition could slow feature shipping during integration, according to industry commentary.
Moon Invoice
Pros
- Runs natively on Mac, Windows, iOS, Android and Linux as well as in the browser, so you can bill from almost any device.
- Annual plans start at about 80 USD a year in directory listings, cheaper than most accounting suites.
- Supports a wide range of payment gateways, including Stripe, PayPal, Square, Braintree, Razorpay, Venmo, Cash App and UPI.
- Offers more than 66 invoice templates and many document types, such as estimates, purchase orders, credit notes, delivery challans and proforma invoices.
- Account owners can set Add, Edit or Delete access for each module, or hide a module from a team member.
- Active development: the iOS app received several updates in late 2026, including WhatsApp Business API integration.
Cons
- Users on G2 and the App Store report unreliable data sync between mobile and desktop apps.
- Reviewers, including The CFO Club, note limited customization.
- No published SOC 2 or ISO 27001 certification; the site only mentions multi-layered cloud security.
- Accounting depth is light: the vendor does not document a chart of accounts, balance sheet, audit trail or accountant role.
- Pricing is confusing: listings and app store in-app purchases show several overlapping plan names and prices, and frequent promotions change the price you pay.
- Starter limits you to 25 active clients.
