The verdict
Relay is the best free business bank for solo operators who want structured cash management — specifically anyone running the Profit First method, anyone with a bookkeeper who needs their own account access, and freelancers or creators with irregular income who want automatic tax bucketing without spreadsheets or willpower.
Its defining feature is genuinely different from anything Mercury or traditional banks offer: up to 20 real checking accounts, each with its own routing number and debit card, not virtual envelopes or ledger entries. When you create a Taxes account in Relay, your accounting software sees it as a separate bank account. That matters for reconciliation. It matters for clarity. And it matters when your CPA wants to verify that the $18,000 sitting in your tax account actually exists and is actually separate from your operating cash.
That said, two things about Relay's infrastructure deserve transparency that Relay's own marketing doesn't offer prominently. First, Thread Bank — Relay's banking partner — received an FDIC enforcement action in 2024 over compliance deficiencies. Relay continues to operate normally and deposits remain insured up to $3 million through Thread Bank's sweep program, but you should know your bank's regulatory history. Second, account freeze complaints appear consistently on Trustpilot and Reddit — triggered by Thread Bank's fraud detection — and while Relay launched a dedicated Account Protection Team in 2026 to address this, the problem hasn't fully resolved based on recent reviews.
Neither issue is a reason to avoid Relay. They are reasons to understand what you're choosing and why.
1. Outgoing wire transfers require the Grow plan ($30/month) — not available free. 2. Thread Bank, Relay's banking partner, received an FDIC enforcement action in 2024. Deposits remain insured up to $3M. 3. Account freezes triggered by fraud detection are a recurring complaint — typically resolved within days, but worth knowing. 4. Mobile check deposits can take 7–10 business days to clear.
What Relay actually is
Like Mercury, Relay is a financial technology company, not a chartered bank. Banking services are provided through Thread Bank, an FDIC-insured member institution. Your deposits are held at Thread Bank, not at Relay, and are protected by FDIC insurance up to $3 million through Thread Bank's deposit sweep program — twelve times the standard $250,000 single-bank limit.
Thread Bank received an FDIC enforcement action in 2024 for compliance deficiencies. This is public record and available on the FDIC's enforcement actions database. Thread Bank continues to operate as a fully insured institution and Relay accounts remain functional. The enforcement action relates to internal compliance processes at Thread Bank, not to customer deposit safety. Your funds are protected. But it's part of the due diligence picture that Relay's own marketing understandably omits.
The practical implication for solo operators: your deposits are insured, Relay is functional and well-regarded overall, and the bank infrastructure concern is real but not acute. If you're holding more than $3 million in business deposits, this becomes more relevant. At typical solo operator balances, the $3 million FDIC coverage is effectively unlimited protection.
Pricing — the three tiers
Relay runs three plans. The Starter plan is free and covers everything most solo operators need. The Grow plan at $30 per month adds features relevant to growing operations. The Scale plan at $90 per month is built for teams and businesses with complex financial workflows — essentially out of scope for a one-person practice.
| Feature | Starter (Free) | Grow ($30/mo) | Scale ($90/mo) |
|---|---|---|---|
| Checking accounts | Up to 20 | Up to 20 | Up to 50 |
| Savings APY | 0.91% | 1.55% | 2.68% |
| Debit cards | Up to 50 | Up to 50 | Unlimited |
| QuickBooks / Xero | ✓ (all plans) | ✓ + auto bill import | ✓ + auto bill import |
| Bookkeeper access | ✓ | ✓ | ✓ |
| Outgoing wires | ✗ | ✓ (free) | ✓ (free) |
| Faster ACH | Standard | Same-day | Same-day |
| Auto bill import (QB/Xero) | ✗ | ✓ | ✓ |
| Multi-step bill approval | ✗ | ✓ | ✓ |

The practical guidance on plan selection: most solo operators should start on Starter and stay there. The free tier gives you the core value proposition — 20 checking accounts, bookkeeper access, QuickBooks and Xero bank feeds, and automated percentage-based transfer rules between accounts. The Grow plan is worth considering if you send regular wire transfers to clients or contractors (wires are only available on Grow), or if you want automatic bill import from QuickBooks. The APY difference between Starter and Grow (0.91% vs 1.55%) is real but unlikely to justify $30/month on typical solo operator cash balances.
The sub-account system — Relay's actual differentiator
This is the feature that makes Relay meaningfully different from Mercury and every traditional business bank. It's worth understanding precisely what it is and what it isn't.
Relay gives you up to 20 checking accounts — not virtual envelopes, not sub-ledger entries, not budget categories within a single account. Each account has its own unique routing number and account number. Each appears as a separate bank account in QuickBooks or Xero when you connect your bank feeds. Each gets its own debit card. Money in your Taxes account is genuinely in a separate account that can't accidentally be spent from your Operating account.
This matters more than it sounds. The reason most solo operators fail at the Profit First method isn't that they disagree with the concept — it's that keeping money in different buckets within one account requires constant vigilance. You check your balance, you see $22,000, you feel flush, you spend. The money in your "mental taxes bucket" doesn't look different from your operating cash. Relay's separate accounts fix this at the infrastructure level. You see four accounts with four balances. Taxes shows $6,400. You don't spend it. The system enforces the behavior rather than relying on your discipline.
Relay's automatic transfer rules extend this further. You can set a rule that when money arrives in your Operating account, it automatically moves a specified percentage to your Taxes, Reserve, and Owner's Pay accounts. Set it once during setup. Every deposit allocates correctly from that point without any manual action.
Create five accounts: Operating (primary), Profit (5–10% of deposits), Owner's Pay (50% of deposits), Taxes (25–30% of deposits), Operating Expenses (30–35% of deposits). Set automatic transfer rules to allocate each deposit on arrival. Your bookkeeper sees five separate accounts in QuickBooks. Your CPA sees five separate account balances at year-end. The system runs itself.
Integrations — what connects and how well
Relay's accounting integrations on the Starter plan connect your bank feeds to QuickBooks Online and Xero automatically. Transactions sync and appear in your accounting software without manual CSV exports. This is the baseline and it works reliably.
The Grow plan adds automatic bill import — invoices and bills from your QuickBooks or Xero sync into Relay's bill pay dashboard, where you can approve and pay them. This is useful for agencies paying contractors or anyone managing vendor bills, but most solo consultants don't need it on the free tier.
Relay does not have a native Stripe integration. If clients pay you via Stripe, you'll manage that reconciliation separately — Stripe payouts hit your Relay Operating account and sync from there to your accounting software, but there's no direct Stripe-Relay connection comparable to what Mercury offers. For consultants billing via invoice (ACH, wire, or check), this isn't a meaningful limitation. For creators with Stripe-powered product sales, it's worth noting.
On the payment acceptance side, Relay supports ACH and wire receiving at no cost. The platform does not directly process credit card payments — if you need to accept cards, you'll use a separate processor (Stripe, Square) and receive the payouts via ACH into your Relay account.
Account freezes — the honest picture
This is the most consistent complaint in Relay's Trustpilot reviews and Reddit discussions, and it's worth addressing directly rather than burying in fine print.
Thread Bank's fraud detection system flags accounts for review based on transaction patterns — large incoming payments from new clients, sudden changes in deposit volume, certain business types, and other triggers. When an account is flagged, Relay freezes it pending review. The freeze can last anywhere from hours to weeks. During a freeze, you cannot access your funds.
For a solo operator who receives a large project payment at month-end and relies on that cash for payroll, contractor payments, or rent, this is a serious operational risk — not a theoretical one. Multiple reviewers describe being frozen for 5–10 business days with limited support visibility into the timeline.
Relay launched a dedicated Account Protection Team in early 2026 specifically to address escalations. Response times have improved according to more recent reviews, but the underlying fraud detection behavior hasn't fundamentally changed. The risk exists.
How to mitigate it: don't rely on Relay as your only business bank. Many solo operators use Relay for its cash management features and keep a secondary account (Mercury or a traditional bank) for receiving large client payments. The funds then transfer to Relay for allocation. This adds a step but eliminates the freeze risk on incoming payments.
Features worth knowing about
Bookkeeper and accountant access. You can invite your CPA, bookkeeper, or accountant with controlled permissions on the free Starter plan. This is a meaningful advantage over Mercury, which gates accountant access above the basic view-only role. For operators who actively work with an accountant, this makes Relay's free tier comparable to Mercury's paid tiers on this specific feature.
Bill pay. Relay includes a bill pay feature that lets you email invoices directly to a dashboard, or sync them from your accounting software on the Grow plan. You can approve and pay bills directly from Relay, set up multi-step approval workflows, and pay via ACH or check. For solo operators, the main use case is paying contractors and vendors without leaving the banking dashboard.
Expense management. All users can upload receipts and manually categorize expenses before syncing to accounting software. On Grow, physical and virtual debit cards can have individual spend limits and category restrictions — useful if you have a team member you want to give card access with guardrails.
Savings accounts. Relay offers savings accounts with a 0.91% APY on Starter, rising to 1.55% on Grow and 2.68% on Scale. These are significantly below Mercury's Treasury product in yield (Mercury Treasury earns a competitive rate comparable to high-yield savings accounts), but the Relay savings account is straightforward and integrates cleanly with the sub-account system — you can set automatic transfers between your checking sub-accounts and savings.
Who Relay is right for
Use Relay if: You want to run Profit First and need real separate accounts (not budget categories). You work with a bookkeeper who needs their own login on the free plan. You have irregular income and want automatic tax allocation without manual transfers. You're a freelancer, creator, coach, or consultant who wants clean cash management without complexity. You don't send regular wire transfers to clients (those require Grow at $30/month). You want a platform that's genuinely designed around the way a solo service business manages money.
Consider Mercury instead if: You use QuickBooks, Xero, or Stripe and want the deepest native integrations. You send wire transfers regularly and don't want to pay $30/month for the privilege. You want $5M FDIC coverage rather than $3M. You're concerned about the Thread Bank enforcement history. You want credit products (the Mercury IO card) in the same banking ecosystem.
Consider running both: A practical setup that many solo operators use — Mercury as the primary account for receiving client payments and integrating with accounting software, Relay for cash management and allocation. Money arrives at Mercury, gets allocated to Relay sub-accounts via weekly transfer, Relay handles the tax and reserve buckets. More complex to set up, but it combines the strengths of both platforms without the weaknesses of either.
Relay vs Mercury — the decision
Both are free. Both are excellent for digital service businesses. The choice is genuinely situational rather than one being clearly superior.
Choose Relay when cash management structure matters more than integration depth. The 20-account system, automatic allocation rules, and free bookkeeper access are Relay's genuine advantages — and they solve a real problem that Mercury doesn't address as well.
Choose Mercury when integration depth matters more than cash management structure. Native QuickBooks, Xero, and Stripe connections, free wire transfers, and $5M FDIC coverage are Mercury's genuine advantages — and they solve a different real problem.

Opening a Relay account
The application takes 10–15 minutes online. You'll need your EIN, business formation documents, and personal ID. Unlike Mercury, Relay does accept sole proprietors with an EIN — you don't need an LLC or S-Corp, though having one strengthens your application and your business credit profile overall.
Approval typically takes 1–3 business days. Once approved, create your sub-accounts before making any deposits. Name them clearly (Operating, Taxes-25%, Reserve-60-days, Owner-Pay) and set up your automatic transfer rules immediately. The setup takes about 30 minutes and then runs without any ongoing management.
Connect QuickBooks or Xero during setup under Settings → Integrations. Each sub-account will appear as a separate bank account in your accounting software. If you work with a bookkeeper, invite them immediately — give them the appropriate permission level and let them reconcile from day one rather than catching up later.
