Why teams choose Xace integrations

Three integration layers. One operating system.

Accounting sync, workflow automation, and a production-grade API — each layer solves a distinct problem. Together they close the gap between your accounts and your business.

Accounting Sync

Auto-reconcile Xero and QuickBooks in real-time. Every transaction arrives with categories, tax codes, and contacts already mapped.

Workflow Automation

Turn payment events into Slack alerts, Jira tickets, and custom workflows via Zapier — triggered automatically, zero code required.

Webhook Events

Real-time event streams for every transaction, approval, balance change, and FX conversion — routed to wherever you need them.

Integration workflows

Connect, automate, and build your integration layer

Explore how accounting sync, event automation, and the developer API fit together — and which layer is right for your use case.

Auto-reconcile your books without lifting a finger

Xero and QuickBooks sync in real-time as transactions clear. Categories, VAT codes, and contact records mapped automatically — so your month-end is already done before the month ends.

Real-time transaction sync to Xero

Every Xace transaction lands in Xero immediately with auto-matched categories, tax codes, and contact records — no manual entry, no reconciliation lag.

Month-end reconciliation in minutes

Automated statement matching eliminates manual bookkeeping. Accounts reconcile continuously against your accounting records throughout the month.

QuickBooks and multi-entity sync

Native QuickBooks integration keeps every entity in sync — across currencies, jurisdictions, and account hierarchies — without extra admin overhead.

Accounting sync

Books that balance themselves

Real-time Xero and QuickBooks sync means reconciliation happens as transactions clear. No end-of-month catch-up, no manual category mapping, no missed VAT codes. Finance teams get back the hours they spent re-keying data — and fewer discrepancies to explain at audit time. Every entry arrives matched, coded, and ready.

Workflow automation

Every financial event can kick off the right action

Payments and approvals should not live in a silo. Wire them to Slack for instant team visibility, Jira for compliance tracking, Google Sheets for reporting, or any tool in your stack via Zapier. When money moves, your operations move with it — automatically, without a developer on every new workflow.

API-first integration

When you need the full integration layer

Build exactly the integration your operating model needs. The Xace REST API provides full access to accounts, transactions, payments, FX, and events. Webhooks deliver real-time event notifications to any endpoint. A full-featured sandbox environment lets you build and verify without touching live accounts or live data.

Why integrations matter

Finance gets stronger when it lives inside the rest of the operating stack

Connected apps remove the lag between a financial event happening and the right team being able to act on it. When accounting, notification systems, and workflows stay in sync with your accounts, finance and operations teams spend less time on data entry and more time controlling outcomes.

Whether you are syncing transactions to Xero, firing Slack alerts when a payment clears, automating affiliate payouts via Zapier, or building a custom treasury dashboard on the Xace API — the integration layer is what makes your financial infrastructure feel fast and intentional rather than manual and reactive.
