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.

Rompslomp

Pros

• The interface avoids accounting jargon, so freelancers without bookkeeping knowledge can file VAT and ICP returns directly to the Belastingdienst.
• A free Starter plan and paid plans from 8.95 euro per month keep entry costs low for zzp'ers.
• Hours and mileage tracking are built in and can be invoiced directly, with GPS links to TrackJack and YesHugo.
• The bookkeeper dashboard lets accountants manage several client administrations with granular access rights and XML audit file exports.
• Peppol e-invoicing is included, and paid accounts are registered automatically to receive e-invoices.
• As a Visma company, it has corporate backing and uses the Visma bank connection.

Cons

• The interface is Dutch only. A Trustpilot reviewer asked for English, and the vendor said it was on its radar.
• On Rompslomp's own comparison page, support is listed as email-only, and some Trustpilot reviews complain about unreachable support.
• Lower tiers have tight caps: Basic allows only 10 invoices and 10 expenses a month, and recurring invoices start at Professional.
• Usage charges add up: 1.50 euro per extra Starter invoice since November 2026, plus paid credits for scans and e-invoices and transaction fees.
• There are few named integrations compared with SnelStart or e-Boekhouden.nl, and Onderneming.nl notes it has no automatic Mail & Herken for emailed invoices.
• There is no published security certification or trust page specific to Rompslomp.
