Starling vs Monzo Business Account: Which Is Better?

Which Is Better for UK small businesses choosing between two free FSCS-protected accounts?

For most UK small businesses, Starling is the better default if you might need an overdraft or regularly send high volumes of domestic payments. Monzo Pro is better if cashflow visibility, VAT ring-fencing, and tax-pot automation matter more than credit access.

Starling wins on volume. No fee per domestic transfer, full stop. If you pay twenty suppliers a month, the maths is simple: Starling costs nothing, Tide costs £4. Monzo matches Starling on free domestic transfers at the entry tier — the differentiation is elsewhere.

Starling wins on overdraft. Monzo doesn’t offer one on its business account. Say your biggest client pays sixty days late in November. You need to cover payroll. With Starling you call on the overdraft. With Monzo you’re looking at a separate credit facility — slower, more friction.

Monzo Pro wins on cashflow tools. The tax-pot auto-sweep sets aside a percentage of every incoming payment to a named VAT pot before you can spend it. If you’ve ever reached quarter-end and found the VAT reserve depleted, that’s the problem it solves. £5 a month.

Starling vs Monzo Fees and Charges

Starling Business: no monthly fee, no domestic transfer fees, no minimum balance. The account is free at every volume level. There are no paid business account tiers for standard current accounts. Verify current plan structure at starlingbank.com.

Monzo Business: free standard plan with core banking. Pro at £5/month per user adds named tax pots, automated cashflow forecasting, and priority customer support. Domestic transfers are free on both tiers. Confirm current pricing at monzo.com before applying.

International transfers: both providers charge for outbound international payments. Neither offers multi-currency wallets. Starling sends international transfers via SWIFT with a fee per transaction. Monzo converts at the Mastercard exchange rate plus a fee. For high-volume international payments, consider Wise or Revolut alongside.

Cash deposits: neither accepts cash through the app. Both have third-party cash deposit partnerships (PayPoint network for both), but fees apply and the process is not designed for regular cash-heavy businesses. If you deposit cash daily, you’ll need a high-street account alongside either of these.

Starling vs Monzo Features and Tools

The feature difference we’d flag first is accounting integration depth. Starling connects to Xero and FreeAgent. Monzo connects to Xero and QuickBooks. Neither integrates with Sage. If your accountant works in Sage, this comparison ends early.

Starling’s FreeAgent integration is a meaningful add-on. FreeAgent is a full accounting package — invoicing, expenses, tax returns, payroll for sole traders. If you’d otherwise pay separately for FreeAgent, the Starling integration reduces that overhead. Check current terms at starlingbank.com for the exact FreeAgent deal at the time you open.

Monzo Pots are the standout banking feature. A Pot is a named sub-balance inside your account — move money in, see it sitting separate from your available balance. Pro adds named tax pots that auto-sweep a percentage of incoming payments. If VAT gets spent before quarter-end, that’s the fix.

Neither provider offers built-in invoicing inside the banking app. If you need to send invoices from your account — in the way Tide or ANNA allow — you’ll use a separate accounting tool with either Starling or Monzo. That’s not a criticism; it’s a product choice both have made.

Starling vs Monzo International Payments

Neither Starling nor Monzo is a multi-currency account in the Revolut or Wise sense. Both hold balances in GBP. Both charge for international transfers. If you invoice clients in euros, receive USD payments, or pay overseas suppliers regularly, you’ll want Revolut or Wise alongside either account.

Starling does offer a Euro business account as a separate product — a euro-denominated current account for businesses trading with EU counterparties. This is separate from the standard GBP account and has its own eligibility conditions. Verify current availability and features at starlingbank.com.

Monzo Business is GBP-only at every plan tier, confirmed May 2026. All incoming foreign currency payments are converted at the Mastercard rate on arrival. There are no currency wallets, no foreign-currency invoicing, and no way to hold a balance in euros or dollars.

For this comparison, international payments is not the decision axis. We’d point you to Revolut or Wise instead — both handle cross-border volume better than either Starling or Monzo.

Starling vs Monzo Customer Reviews and Reputation

We looked at published Trustpilot and app store ratings for both in May 2026. Starling Business sits around 4.3–4.5 stars across tens of thousands of reviews. Monzo Business is comparable. App store ratings for both track above 4.5 on iOS and Android.

Starling complaints cluster on overdraft eligibility. The underwriting criteria aren’t published, so a rejection arrives without explanation. You apply, you wait, you get a no with no workable path to a yes. If overdraft access matters to your business plan, verify current eligibility criteria directly.

Monzo complaints cluster on account closures with limited explanation — a small proportion of reviewers, but a consistent pattern. Automated compliance checks flag accounts; the review that follows isn’t always fast. Neither provider is unusual in this, but it’s worth knowing before you route payroll through either account.

Both run app-first support: in-app chat is the primary route for both. No phone line to a business advisor at any tier. If that matters to you in a crisis — Friday 5pm, payment stuck — plan around it.

Starling vs Monzo for Overdraft Access vs Tax Pot Automation

The overdraft question is the most specific differentiator between these two accounts. Monzo doesn’t offer one. Starling does, subject to eligibility. If you run a business that needs a credit buffer in its current account — seasonal cash flow, slow-paying clients, occasional stock purchases — this is the deciding question.

Starling’s overdraft is unsecured and assessed at application. Eligibility criteria aren’t publicly detailed; approval depends on the business financial profile assessed at the time. An overdraft at Starling doesn’t automatically come with the account — you apply for it separately. Confirm current terms at starlingbank.com.

Monzo’s answer to cashflow gaps is the Pro cashflow forecasting tool, not credit. The automated forecasting on Pro shows projected cash-in and cash-out based on your transaction history. That’s useful for planning; it doesn’t replace credit when you actually need to bridge a payment.

Our view: if overdraft access could matter to your business — even occasionally — Starling is the only viable choice between the two. If you’ve never needed a credit buffer and your main concern is keeping VAT ring-fenced, Monzo Pro answers that better.

Downsides of Starling and Monzo

Neither Starling nor Monzo integrates with Sage. We’d flag this first: your accountant asks for a Sage-compatible bank feed; you export a CSV. Repeated every month. If Sage is central to your accountant’s workflow, check Tide instead.

Monzo has no overdraft. That gap is real for businesses that occasionally need a credit buffer. The Pro cashflow forecasting shows you the gap coming; it doesn’t fill it. If you ever need to bridge a slow payment month, you’ll need a different provider or a separate credit facility.

Cash deposits are limited for both. PayPoint handles deposits via a network of newsagents and convenience stores, with fees per deposit. It’s usable for occasional cash, not daily trading cash. A market trader banking £400 a day needs a high-street account alongside either of these.

Neither offers relationship banking. No named account manager, no branch, no phone line to someone who knows your account. App-first means app-only when something goes wrong. That’s a trade-off both providers make by design — know what you’re trading for the free account.

Alternatives to Starling and Monzo

If neither Starling nor Monzo fits, here are the four alternatives we’d consider before looking further. Each solves a different gap.

• Tide — built-in invoicing, expense categorisation, and direct Sage integration. Better than both for Sage-based accountant workflows. Trade-off: 20p per outgoing UK transfer on the free plan, e-money safeguarding rather than FSCS.
• ANNA Money — AI-powered tax and expense automation with invoicing built into the banking app. Better than Monzo Pro for businesses that want fully automated VAT and tax submissions without a separate accounting tool.
• Revolut Business — 25+ currency wallets, interbank FX inside plan allowances, team expense cards on paid tiers. Better than either for businesses with international payments as a regular need. PRA-licensed for new accounts from 11 March 2026.
• Mettle by NatWest — free FSCS-protected account with NatWest backing and FreeAgent integration. Worth considering if NatWest’s institutional credibility matters to your business.

Final Verdict: Starling or Monzo?

Starling is the better default for UK businesses that need overdraft access or send high volumes of domestic payments. Monzo Pro is the better choice for businesses where cashflow visibility and tax ring-fencing matter more than credit. Both are free FSCS-protected PRA banks at the entry tier.

Choose Starling if you might need an overdraft. It’s the most concrete reason to pick Starling over Monzo — Monzo doesn’t offer one. Even if you’ve never used a business overdraft, having the option costs nothing on a free account.

Choose Starling if you pay a lot of domestic suppliers. No fee per transfer means no compounding cost as payment volume grows. The accounting is cleaner and the operational cost stays at £0 regardless of whether you pay five suppliers or fifty.

Choose Starling if your accountant uses FreeAgent. The integration removes a manual step in your month-end workflow. Confirm the current FreeAgent terms at starlingbank.com — the offer details have changed historically.

Choose Monzo Pro if you struggle to keep VAT aside. The auto-sweep on Pro — setting aside a percentage of every incoming payment to a named VAT pot — removes a recurring decision. At £5/month, it’s cheaper than most bookkeeping remediation.

Monzo if cashflow visibility is the issue. The Pro tier automated forecasting shows projected cash-in and cash-out based on transaction history — Starling doesn’t offer the equivalent. If you run close to the line month-to-month, seeing the next thirty days of cash positions is useful.

Choose Monzo if your accountant uses QuickBooks and you want the cleanest integration available. Starling doesn’t connect to QuickBooks. If your workflow is QuickBooks-anchored, Monzo saves you the export step.
