Overview
Mercury
Mercury is a unified financial platform built to help founders and operators hold, move, and understand their money in one place. With Mercury, you can manage cards, bill pay, invoicing, spend management, real-time insights, and intelligent categorization. Connect Mercury to Xero to streamline your accounting workflow and keep transactions organized and up to date.
Banking
Mercury brings banking* and financial tools together in one place, helping teams hold, move, and organize funds. Create sub-accounts to separate money by purpose and keep day-to-day cash management simple.
Spend management
Mercury’s IO card offers up to 1.5% cashback** on purchases, plus virtual cards and spend controls to help teams stay on budget. Transactions can sync to Xero with enriched merchant details and suggested GL codes to streamline reconciliation. **The IO Card is issued by Patriot Bank, N.A., Member FDIC, pursuant to a license from Mastercard International Incorporated. To receive cash back, your IO charge card account must be open and in good standing, meaning they cannot be suspended, restricted, past due, or otherwise in default.
Bill pay
Pay vendors directly from your account with AI that reads invoices, populates details automatically, and remembers recipients. Duplicate detection catches repeat bills before they go out. Approval workflows let you control who can authorize payments and at what thresholds. All bill data syncs directly to Xero with GL codes attached.
Invoicing
Create and send professional invoices from the same platform where you manage your money. Customers can pay by credit card, Apple Pay, Google Pay, ACH, wire, or ACH debit. Set up recurring invoices and one-click payment reminders. When an invoice is paid, the payment syncs to Xero automatically so books stay current.
Accounting automations
Mercury's free Xero integration pulls in your GL codes and lets you categorize transactions before they hit your ledger. AI pre-fills GL codes based on your history and improves over time. Assign codes to bills, card transactions, reimbursements, wires, ACH, checks, and internal transfers from one dashboard. Sync is one-way (Mercury to Xero), giving bookkeepers a clean review step before data lands in the ledger.
Built for bookkeepers
A dedicated bookkeeper role gives accountants access to categorization and Xero sync settings—without exposing sensitive account details like balances or routing information. Clients get a unified financial platform for banking and financial workflows, while bookkeepers get structured data that can sync to Xero with a clear review.
Getting started
Connect in minutes from Settings > Integrations in Mercury. The Xero integration is free on all plans. Paid plans start at $35/month for advanced invoicing and larger team reimbursements. *Mercury is a fintech company, not an FDIC-insured bank.

Mercury + Xero
Mercury’s Xero integration syncs transaction data from across Mercury — including banking* activity, bill pay, invoicing, cards, and expense reimbursements — into Xero for reconciliation and reporting. The enriched integration is completely free.
How it works
Mercury sends a bank feed to Xero automatically multiple times a day. The enriched integration layers on GL codes, counterparties, attachments, and notes that you apply in Mercury before syncing. When enriched data syncs, it updates the existing bank feed entry in Xero rather than creating duplicates.
Transactions follow a three-step workflow on the Accounting page: Needs Review, Mark as Ready, and Sync. Mercury’s AI pre-fills GL codes based on your history (indicated with a sparkle icon) and improves over time. You can also create categorization rules that auto-apply GL codes based on transaction attributes.
What syncs
GL codes can be applied to bills, credit and debit card transactions, expense reimbursements, wires, ACH transfers, checks, and internal transfers. Recurring payments inherit the GL code from the first transaction. Treasury can sync via bank feed. Invoice payments sync automatically once paid.
Spend management
Corporate card transactions and employee expense reimbursements flow through the same Accounting page and sync to Xero with GL codes and receipt attachments. Admins set spend limits per card, configure receipt and note policies, and send automated reminders to employees who haven’t uploaded receipts. Employees can categorize their own card spend and submit expenses on mobile. Bookkeepers review and correct everything on the Accounting page before syncing to Xero, so the data arrives clean.
Bill pay
How it works: Assign a GL code during payment to create an unpaid bill record in Xero. Once paid, the bill is automatically marked as paid. If no invoice number, date, or due date is provided, the payment syncs as an expense instead.
Xero-specific details
Xero requires counterparties, and Mercury pre-fills them. Credit card transactions feed into a dedicated Mercury Credit account (#MERC) in Xero. The sync is one-way (Mercury to Xero), so GL code updates should be made in Mercury.
Access
Admin and Bookkeeper roles can manage the integration and syncing. Employees can categorize their own transactions but cannot access the Accounting page or sync controls.
