When an app says it connects to more than 12,000 institutions, it's almost always quoting its data provider. Here's where the figure comes from, what 'supported' does and doesn't promise, and how to read the results when you link your own accounts.
If you've been comparing money apps, you've seen the line: connects to more than 12,000 financial institutions. It sounds like a feature the app built. Usually it isn't. That figure comes from Plaid, the data network many budgeting apps use to link bank accounts, and any app built on Plaid can point to the same reach. So an app that connects 12,000+ institutions is really telling you which plumbing it uses.
That's still useful information. It just answers a different question than the one you care about, which is whether your five or eight accounts will connect, stay connected, and bring over the data you actually need. This guide explains what the number covers, why 'supported' isn't the same as 'works well for every account type', and how to read what comes back when you link your own institutions.
Where the 12,000 figure comes from
Plaid says it connects to more than 12,000 financial institutions. That count spans several countries, including the US and Canada, and it includes everything from the largest banks down to small credit unions, brokerages, loan servicers and payment apps.
Two things follow from that. First, a big share of those 12,000 aren't relevant to you. If you live in Ohio, the count includes institutions in other countries and community banks in other states you'll never use. Second, most of the list is the long tail. A relatively small number of large banks serve a big share of customers, while thousands of small institutions each serve a few thousand members. The long tail is where connection quality varies most, and it's also where a single missing account can leave a hole in your numbers.
Other aggregators, such as MX, Finicity and Flinks in Canada, publish their own counts, and some apps use more than one provider. A bigger combined number can mean a fallback when one connection fails. It doesn't mean your particular credit union works better.
Supported isn't the same as fully supported
An institution appearing in the search box means you can probably sign in to it. It doesn't mean every type of data comes through. Aggregators treat data in separate pieces, and each institution supports a different mix:
So a brokerage might show up, link fine, and still only give you a single account balance with no holdings. A student loan servicer might show the balance but not the interest rate. That's not the app hiding things. It's what that institution makes available through the connection.
Balances
The most widely supported piece, available almost everywhere that connects
Transactions
Standard for checking, savings and credit cards, patchier for loans and investments
Investment holdings
Individual funds and stocks in a brokerage or retirement account, supported less consistently
Loan details
Interest rate, minimum payment and due date for cards and loans, available at some lenders
What to expect from each kind of account
Here's a realistic picture of what usually comes through, from most reliable to least. Your institutions may do better or worse, but this is a good starting expectation.
Checking and savings
Balances and transactions, usually solid even at mid-sized banks
Credit cards
Transactions and balances, sometimes the statement balance and due date too
Brokerage accounts
A balance almost always, holdings at many larger brokerages
Workplace retirement
401(k), 403(b) and RRSP accounts held by recordkeepers, often balance only
Mortgages and loans
Usually a balance, sometimes rate and payment, occasionally nothing
Payment apps
PayPal or Venmo balances vary, and purchases often show at your bank as one lump transfer
How far back it goes and how fresh it stays
Two details rarely make it onto marketing pages but matter a lot in daily use.
The first is history. When you link an account, the app pulls past transactions. How far back depends on the institution. Some provide a couple of years, some much less. If you want a year-over-year comparison of your grocery spending, check how many months actually arrived. If it's only a few, import older statements as a CSV to fill the gap.
The second is freshness. Linked accounts refresh periodically, often a few times a day, not the instant you tap your card. Pending transactions may appear and then change: a gas station hold of $1 that becomes $52.40, or a restaurant charge that grows when the tip posts. 'Real-time' in money apps generally means 'within hours', which is fine for budgeting and not something to rely on for a balance you're cutting close.
What to look at right after you link an institution
Linking successfully is step one. Before you trust the account, spend two minutes checking what came over. These checks catch the common problems that a coverage number won't tell you about.
- Count the accounts. If your bank login has checking, savings, a card and a line of credit, all four should appear. Some connections skip certain account types.
- Pick the right listing. Large banks sometimes appear more than once, for example separate entries for personal and business banking or for a regional brand. If the link fails, try the other listing before giving up.
- Look at the oldest transaction. That tells you the history depth for that institution.
- For investment accounts, check whether you see holdings or a single number. Either is fine for net worth. Only holdings tell you about allocation.
- For loans and cards, check whether the interest rate and due date came through. If not, add them to your own notes or a debt payoff calculator.
How Sumyfi uses Plaid's reach
Sumyfi links accounts through Plaid, so its reach is Plaid's reach across US and Canadian institutions, read-only, with coverage depending on the bank. When you connect, it asks for transaction data first and picks up loan and investment details where the institution provides them. If those extra details aren't available, the account still links with balances and transactions.
Everything linked feeds the same dashboard: budgets, savings goals, net worth and recurring charges, in USD or CAD. For anything that doesn't connect well, you can add a manual account or import transactions from a CSV or Excel file, and both of those work on the free plan. Automatic sync is part of Premium, which has a 7-day free trial, enough time to link your accounts and run the checks above before deciding.
We won't claim Sumyfi connects to 12,000 institutions as if that were our own achievement. It's Plaid's number. What you should judge us on, and any other app, is whether your accounts link cleanly and stay that way.
