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.

WISO MeinBüro

Pros

• Writing quotes and invoices is fast, and OMR reviewers say this works even for users with no accounting knowledge.
• E-invoices in the XRechnung and ZUGFeRD formats are included in every plan.
• Data can be exported to DATEV and filed through ELSTER, and a tax adviser login is included in all plans.
• Bank payments are matched to invoices automatically from the Buchhaltung plan upward.
• Founders get 50 percent off the first year of the basic plan.

Cons

• Experte.de says it has no double-entry bookkeeping and cannot produce a BWA or profit and loss statement.
• Experte.de reports that the phone line is often busy and that email replies took more than two weeks.
• You can only buy a one-year contract paid in advance, and it renews automatically.
• OMR users complain about regular price rises and costly add-on modules.
• The cloud version can be slow, and Experte.de says it cannot issue invoices in other currencies.
