If you are setting up banking for an online store, the Mercury vs Relay question comes up fast. Both are online-first business banking platforms with no branches, both are popular with ecommerce operators, and both start at $0 a month. The difference is what each one is built to do. I run my own stores and help coaching students and done-for-you clients at Ecommerce Paradise set up the legal and financial side of high-ticket dropshipping, so I judge a bank on three things: how many accounts you get, what it costs to pay suppliers, and what happens to your cash while it sits there.
Everything below comes from each company’s own pricing and product pages as I reviewed them. Where a page does not show a number, I say “not shown” instead of guessing, and you should confirm current terms before you open anything. Some links in this article are affiliate links, which means I may earn a commission if you sign up, at no extra cost to you.
Before you open either account, the business behind the store needs to exist on paper. My guide to business formation for high-ticket dropshipping covers that foundation, and if you are still getting oriented, start with what high-ticket dropshipping is. The rest of this article assumes you already have an LLC and an EIN.

The Fundamental Difference Between These Two Platforms
Mercury and Relay are both financial technology companies, not banks. Mercury holds deposits at partner banks, including Choice Financial Group and Column N.A. Relay’s banking services are provided by Thread Bank, Member FDIC. In day-to-day use that means you apply online, manage everything in an app, and never walk into a branch.
Where they differ is the shape of the product. Mercury is built around a clean, low-cost account for moving money: free ACH, free domestic wires, and a $0 base plan. Relay is built around structure. It gives you 20 checking accounts on its Starter and Grow plans and 50 on Scale, unlimited users on every plan, and bill pay and bookkeeping tools that get stronger as you move up the tiers.
That structure is why Relay shows up so often in Profit First conversations. Profit First is a cash management method where every dollar of revenue gets split into separate accounts for taxes, profit, owner pay, and operating costs. You can do that with a handful of accounts at almost any bank, but Relay’s account limits make it the easier fit if you want to run that system at a bigger scale.
Pricing: Two Different Models
Mercury’s base plan is $0 a month with no minimum balance, and for most online stores it covers everything needed. Mercury Plus is $29.90 a month on the pricing page, while the FAQ says paid plans start at $35, so confirm the number when you sign up. Mercury Pro is $299 a month. I would only look at the paid plans if the base plan is missing something specific you need, and the pricing page is the place to see what each tier includes today.
Relay has three tiers. Starter is $0 a month, Grow is $30 a month, and Scale is $90 a month, shown on the page as discounted from $120 under a limited-time discount. Annualized, that is $360 a year for Grow and $1,080 a year for Scale. Each step up adds features and a better savings rate, which I break down in the interest section below.
The honest way to compare them is to start at the free tier of each. Both are free, and both are good enough to open an account and see how the workflow feels. Upgrading only makes sense when you can point to a specific benefit that is worth more than the monthly fee.
Accounts, Cards, and the Profit First Setup
Relay gives each business 20 checking accounts on Starter and Grow and 50 on Scale. Debit cards are available up to 50 per cardholder per checking account, and every plan allows unlimited users. For a store with a virtual assistant, a bookkeeper, and a media buyer, that means everyone can have their own card tied to the right account without sharing logins.
Here is how I would set up a high-ticket dropshipping store with that structure. One account receives payouts from Shopify and your payment processors. A second pays suppliers. A third holds a reserve for refunds and chargebacks, which matters when your average order is large. Then you add separate accounts for taxes, profit, and owner pay. Moving money between them becomes a habit instead of a guessing game.
Mercury’s pages that I reviewed do not state an account limit, so check its site if you plan to run many accounts. If you would rather have the whole business and banking setup built for you, my done-for-you service handles the store, and I walk coaching clients through the financial infrastructure as part of coaching.
FDIC Coverage and Partner Banks
Neither company is an FDIC-insured bank itself, so the details of how coverage works matter. Mercury advertises up to $5M in FDIC insurance through a sweep network of partner banks. Relay advertises up to $3,000,000 through the Thread Bank deposit sweep program, where each program bank covers up to $250,000, including other deposits you hold at that bank in the same ownership capacity.
Relay also notes that pass-through coverage depends on certain conditions being met, and it links its sweep terms and program bank list on the pricing page. Read those terms before you park real money there, and read the equivalent disclosures on Mercury’s site. The FDIC’s deposit insurance page explains the standard $250,000 limit that everything else is built on.
In practice, if your balance stays under $250,000, the headline coverage numbers are not a deciding factor. They start to matter if you hold large reserves, and even then I would spread very large balances across more than one institution rather than rely on any single sweep program.
Savings Rates and What Idle Cash Earns
Relay publishes its savings APY by plan: 1.19% on Starter, 1.87% on Grow, and 3.21% on Scale, as of 9/17/2026 and variable. I could not find a comparable savings APY on the Mercury pages I reviewed, so check Mercury’s site for its current rates before comparing.
Here is the math that decides whether a Relay upgrade pays off. On a $50,000 balance, Starter earns about $595 a year and Scale earns about $1,605, a gain of $1,010 that is less than the $1,080 annual Scale fee. On a $100,000 balance, Starter earns about $1,190 and Scale about $3,210, a gain of $2,020 against the same $1,080 fee. Grow breaks even near $50,000 and starts to pay off above it, since the extra 0.68 percentage points on $100,000 is $680 against a $360 fee.
The takeaway is simple. Do not upgrade for the rate unless you hold enough cash to cover the fee several times over, and remember that variable rates can change.
Wires, ACH, and Paying Suppliers
For a dropshipping business, moving money out is the biggest regular cost, so this section matters more than the headline plan price. Mercury lists ACH and domestic wires as free, USD international wires as free on the standard option or a $15 flat fee with the OUR option, and a 1% conversion fee on non-USD wires.
Relay’s plan page says additional transaction fees apply but does not show ACH or wire fees. The one fee it does call out is that Scale includes same-day ACH at no fee. Before you commit supplier payments to Relay, find its current fee schedule and price out your own volume. If you send eight wires a month, a fee of even a few dollars each adds up over a year.
This is also where finding the right suppliers pays off. My guide to finding suppliers for high-ticket dropshipping shows how to build supplier relationships that support ACH or wire terms, which keeps your payment costs low whichever bank you choose.
Credit Cards and Cash Back
Relay offers the Relay Visa Credit Card, issued by Thread Bank, with cash back of 1% on Starter, 1.25% on Grow, and 1.5% on Scale. Up to five cards per cardholder are allowed per credit account. ATM transactions, money orders, and cash equivalents are not eligible for cash back, and the page does not show a credit limit.
If your store spends heavily on advertising, that cash back is real money. At $20,000 a month in eligible card spend, 1% is $200 a month and 1.5% is $300 a month, so Scale’s extra 0.5% is worth $100 a month against a $90 monthly fee before you even count the better savings rate. Credit limits and approval are not guaranteed, so treat this as an upside, not a plan. I did not find a Mercury credit card on the pages I reviewed, so check its site if a card matters to you.
Bookkeeping and Integrations
Relay lists QuickBooks and Xero integrations on every plan. If you use QuickBooks or Xero for your books, that makes month-end reconciliation less painful. The plans also differ on bill pay: Starter covers bill creation, intake, approval rules, and receipt storage, Grow adds batch vendor payments and bookkeeping automation, and Scale adds bill payment automation plus cash flow insights and forecasts.
Mercury’s integration list was not shown on the pages I reviewed, so confirm that your accounting tool and payment processor connect before you move money over.
Which One Fits Which Operator
If you are just launching your first store and need a free account that makes supplier payments cheap, Mercury is the simpler place to start. The $0 base plan, free ACH and domestic wires, and no minimum balance remove most of the friction.
If you run several stores or brands, work with a team, or want to separate money into many buckets, Relay’s account limits and unlimited users are the stronger fit. If you hold large balances, run the interest math above before you pay for an upgrade.
Many operators end up using both: one as the primary operating account and the other as a second institution for reserves or a specific store. Whatever you choose, make sure your niche and offer are solid first, and my high-ticket niches list is the place to start.
Common Mistakes When Comparing These Two Platforms
The first mistake is comparing headline rates without looking at your own balance. A 3.21% APY sounds great until you work out that you need a big balance to cover the plan fee. The second mistake is skipping the fee schedule. A $0 plan with transaction fees can cost more than a paid plan with free wires, so price out your actual monthly payments.
The third mistake is opening an account before the company exists. Banks need your formation documents and EIN, and the IRS EIN application is free, so never pay a third party for it. If you still need to form your company, I recommend Bizee for a simple setup or Northwest Registered Agent if you want a privacy-focused registered agent.
The last mistake is keeping all your cash in one place. Whichever platform you choose, a second account at a different institution gives you a fallback if one account is ever frozen or delayed.
Frequently Asked Questions
Is Mercury or Relay better for a new ecommerce store?
For most new stores I point people to Mercury first because the $0 base plan, free ACH and domestic wires, and no minimum balance keep costs near zero. Relay’s free Starter plan is a good choice if you want many accounts from day one and plan to follow a Profit First style setup. You can also open both.
How many accounts does Relay give you?
Relay lists 20 checking accounts per business on Starter and Grow and 50 on Scale, with unlimited users on every plan. It does not show a savings account count on the pricing page, so check Relay’s site if that number matters to you.
Is my money FDIC insured at Mercury and Relay?
Both are fintech companies and not banks, so coverage comes through their partner banks. Mercury advertises up to $5M through a sweep network, and Relay advertises up to $3,000,000 through the Thread Bank deposit sweep program, subject to the program terms. Read each company’s disclosures so you understand how it applies to your balance.
Does Relay charge for wires?
The Relay plan page says additional transaction fees apply but does not list ACH or wire fees, apart from noting that same-day ACH is free on Scale. Check Relay’s current fee schedule before you commit supplier payments to it.
Is the Relay Scale plan worth $90 a month?
Only if you hold a large balance or spend heavily on the credit card. On a $100,000 balance, Scale’s 3.21% APY earns about $2,020 more per year than Starter, which covers the $1,080 annual fee. On a $50,000 balance the gain is about $1,010, which does not.
Final Verdict on Mercury vs Relay
Choose Mercury if you want the simplest, lowest-cost account to start taking payouts and paying suppliers. Choose Relay if your business needs many accounts, a team with cards, and a built-in Profit First style structure, and run the interest and fee math before you upgrade.
Neither choice is permanent. Open the free tier of whichever fits best, run your real transactions through it for a month, and add the second account if you find a gap. Just make sure the legal foundation is solid first, and confirm current pricing on each vendor’s own pages before you rely on any number here.
