Bonsai vs Brex

Bonsai (often called Hello Bonsai after its domain) is an all-in-one business management app for freelancers, consultants and small client-service agencies. Instead of stitching together a proposal tool, an e-signature service, a time tracker and an invoicing app, Bonsai covers the whole client lifecycle in one place: win the work, sign the contract, deliver the project, bill and get paid.

The product starts with a lightweight CRM and proposal builder, then turns accepted proposals into contracts with legally reviewed templates and built-in e-signatures. Projects, tasks and a time tracker feed directly into invoices, which clients can pay online by card or bank transfer, with automatic reminders and recurring billing for retainers. A client portal collects files, invoices and messages in one branded space, and higher plans add scheduling, expense tracking, basic bookkeeping and team members. Pricing is per user per month across several tiers (Basic, Essentials, Premium and Elite), with discounts for annual billing; invoicing, contracts and the client portal start from Essentials.

Bonsai is best for solo professionals and agencies of a few people who want professional paperwork without administrative overhead. Its breadth means each module is simpler than a specialist: accounting is basic compared with QuickBooks or Xero, and project management is lighter than Asana. HoneyBook is the closest competitor, particularly for creative businesses in the US, while Moxie and Dubsado offer similar bundles with more workflow automation. Larger agencies that need resource planning and utilization reports should look at professional services tools such as Productive or Scoro.

Brex is a US spend management company founded in 2017 by Henrique Dubugras and Pedro Franceschi and based in San Francisco. It combines corporate cards, expense management, reimbursements, bill pay, travel booking and business accounts in one platform, with the aim of replacing expense reports and manual card reconciliation.

Cards carry real-time controls: budgets per team, project or vendor, merchant restrictions and approval chains. AI matches receipts, flags policy issues and suggests accounting codes that sync to ERPs such as NetSuite, QuickBooks and Xero. The Essentials plan is free and covers cards, expenses and bill pay; Premium adds advanced policies, travel and approvals for a per-user fee; Enterprise supports multiple global entities, local cards in many countries and custom controls.

Brex fits venture-backed startups and mid-market or enterprise companies with US entities, especially those with employees or subsidiaries abroad. Eligibility rules apply, and in 2022 Brex stopped serving many small businesses without venture funding, so very small companies may not qualify. Ramp is the closest rival and is often preferred for its free automation and savings tools; Navan combines travel and expense; Airbase served mid-market finance teams before Paylocity bought it. In practice Brex and Ramp are close, and the decision often comes down to global needs, ERP integration and the offer you receive.

In January 2026 Capital One agreed to acquire Brex for about $5.15 billion, with Pedro Franceschi continuing to lead the business.
