A business bank account can get its activity into QuickBooks Online in one of two ways. The simpler way is a bank feed, and Intuit’s own help center says transactions from a connected bank appear in a For review tab and don’t affect the books until someone matches or categorizes them. The other way is a two-way sync, where changes in either platform update the other. The bank imports the chart of accounts, vendors and classes from QuickBooks, rules or a reviewer code each transaction there, and it reaches QuickBooks already categorized.

All three providers below offer the second route for at least part of what they sync, so the direction of the sync does little to separate them. What separates them for a bookkeeper closing the month is which activity takes which route, how many connections the close depends on, and which ledgers beyond QuickBooks each one reaches. Each description below comes from the provider’s own help center and pricing pages.

Key Takeaways

  • A bank feed leaves the categorizing to be done inside QuickBooks, while a two-way sync imports the chart of accounts so rules can code each transaction before it arrives.
  • Slash’s help center describes two-way sync with QuickBooks Online, Xero, Sage Intacct and NetSuite, bringing in the chart of accounts and vendors and sending back categorized card and bank transactions.
  • Mercury imports QuickBooks GL codes the same way and suggests a code for each transaction, and charges for its enriched NetSuite automations through a paid plan.
  • Relay splits QuickBooks activity by type, with bank transactions in its feed, credit card activity in a card integration and bills in its Bill Pay integration.
  • Ledger coverage separates the three more than sync direction does, and Slash is the only one of them that names both NetSuite and Sage Intacct with no plan restriction.

What to ask about a QuickBooks connection

A connection can be two-way and still leave the close with extra work. These five questions show how much.

  • Does it import the chart of accounts, vendors, customers and classes from QuickBooks, or nothing at all?
  • Is each transaction categorized in the bank’s dashboard before it syncs, or in QuickBooks afterward?
  • Do bank and card activity travel on one connection, or on separate ones?
  • Which other ledgers does it support, and on which plan?
  • How often does it sync, and can someone sync by hand?

1. Slash, two-way sync with four ledgers on both plans

Slash, a financial technology company whose business banking is provided through Column N.A., Member FDIC, codes card and bank transactions against the business’s own QuickBooks chart of accounts before they sync. It serves US-registered LLCs, C-Corps and S-Corps, and does not accept sole proprietors. Its QuickBooks help article, updated April 9, 2026, describes a two-way sync. Once connected, Slash pulls in the chart of accounts, vendors, customers and classes, and a change made in QuickBooks later shows up in Slash on its own.

The coding happens on Slash’s Accounting page. Mapping rules categorize transactions by merchant or other criteria, someone reviews whatever is left, and categorized transactions go to QuickBooks from a Ready to Sync tab. Slash’s accounting page says card and bank transactions are both categorized on Slash and synced to the ledger, so the Slash Visa® Platinum Card and the checking account reach QuickBooks through a single connection.

The help center describes the same structure for three more ledgers. Xero brings in contacts and tracking categories, and Sage Intacct and NetSuite bring in departments, locations and subsidiaries as well. The pricing page lists all four integrations with no plan restriction, on plans that cost $0 on Free and $25 a month on Pro. Slash raised a $100M Series C at a $1.4B valuation, led by Ribbit Capital in April 2026, and reports more than 10,000 businesses on the platform.

A business that later moves from QuickBooks to NetSuite or Sage Intacct keeps the same account and plan. Mercury codes QuickBooks transactions in much the same way, so the difference shows up in the other ledgers more than in the QuickBooks sync itself.

2. Mercury, suggested GL codes and a paid plan for NetSuite coding

Mercury comes closest to Slash on QuickBooks. Its help center says that once Enrichment is set up, Mercury pulls in the business’s QuickBooks GL codes and pre-fills a code for each transaction using AI and the business’s own categorization history. The sync then carries GL codes, classes, receipts and vendor information into the accounting record. Ready transactions go across daily by default, and a team that would rather push them by hand can switch auto-sync off.

On QuickBooks or Xero, all of that comes on the free plan. NetSuite is where Mercury charges. Its pricing page offers NetSuite bank feeds free on every plan, lists NetSuite categorizations among the Pro plan’s features, and says in its FAQ that enriched NetSuite automations need a paid plan starting at $35 a month. A company planning to move from QuickBooks to NetSuite should confirm with Mercury which plan covers the coding it wants. Mercury’s accounting integrations page names QuickBooks Online, NetSuite and Xero, and not Sage Intacct.

3. Relay, separate connections for bank, card and bill activity

Relay splits its QuickBooks connection by the kind of activity. The bank feed pulls settled transactions from Relay checking and savings accounts into QuickBooks Online every few hours. Relay’s QuickBooks guide says card activity does not come through that feed, and transactions on the Relay Visa® Credit Card sync through a separate credit card integration. On the Grow and Scale plans, Bill Pay has its own integration, which syncs vendors, imports unpaid bills and records payments, and the expense management integration codes transactions against categories and vendors pulled from QuickBooks before sending them with receipts attached.

The arrangement keeps bills and expense coding in Relay and leaves bank activity to be reviewed in QuickBooks, with several connections to reconcile at month end. Relay’s integrations page lists QuickBooks Online and Xero, and neither NetSuite nor Sage Intacct, which matters to a business that expects to outgrow QuickBooks.

Choosing between them

Start with where the categorizing should happen. A team that already codes inside QuickBooks is well served by a clean feed, and a team that wants the close to start with coded transactions needs the chart of accounts imported into the bank’s dashboard.

Then count the connections. Checking, a corporate card and bill pay on three separate integrations means three sources to reconcile every month, and one integration carrying all three leaves one.

Last, price the ledger the company expects to run in two years. A business on QuickBooks today that plans to move to NetSuite or Sage Intacct should confirm the integration exists for that ledger, and on which plan, before its first month on the account.

Frequently Asked Questions

What is the difference between a bank feed and a two-way sync in QuickBooks Online?

A bank feed sends settled transactions into QuickBooks, where someone matches or categorizes each one. A two-way sync keeps both platforms up to date. It imports the chart of accounts, vendors and classes into the bank’s dashboard, so each transaction is coded before it goes back to QuickBooks.

Does Slash sync both ways with QuickBooks Online?

Yes, according to Slash’s help center. It imports the chart of accounts, vendors, customers and classes from QuickBooks and pushes categorized transactions back, and it describes the same structure for Xero, Sage Intacct and NetSuite.

Which business bank accounts integrate with NetSuite and Sage Intacct?

Of the three compared here, Slash is the one whose help center describes a two-way sync with both, and its pricing page lists them on every plan. Mercury connects to NetSuite, with bank feeds free on every plan and enriched NetSuite automations on a paid plan, while Relay lists QuickBooks Online and Xero only.
