Connect Xero to Brevo
Automatically sync data from Xero into Brevo. Ikaroa designs, builds and maintains a reliable Xero → Brevo integration so your tools stay in perfect sync.
TL;DR
Connecting Xero to Brevo lets you automatically move invoices, bills and contacts from Xero into Brevo, so your team stops copying data by hand. Xero is cloud accounting software for small business; Brevo is email, SMS and marketing automation (formerly Sendinblue). The integration can be built with a native connector, a tool like Zapier or Make, or a custom API integration for full control. Ikaroa builds and maintains the connection for you.
How do you connect Xero to Brevo?
You can connect Xero to Brevo in three ways: a native integration if one exists, a no-code automation platform such as Zapier or Make, or a custom API integration built directly against the Xero and Brevo APIs. The right choice depends on data volume, how real-time the sync needs to be, and how much custom logic you require. For business-critical or high-volume syncs, a custom API integration is the most reliable. Ikaroa designs, builds and maintains Xero → Brevo integrations end to end.
Teams that rely on both Xero and Brevo usually hit the same wall: the two tools don't talk to each other. Xero handles bookkeeping, invoicing and financial reporting, while Brevo is used for running email and lifecycle marketing campaigns. Without an integration, someone ends up exporting spreadsheets, re-keying records and reconciling mismatches by hand, which is slow, error-prone and doesn't scale. A proper Xero to Brevo integration removes that friction by keeping data flowing automatically from one system to the other.

One source of truth

Faster, automated workflows

Ways to connect Xero and Brevo
Native integration
If Xero and Brevo offer an official connector, this is the quickest path. It covers common fields out of the box, but native connectors are often limited in which invoices and bills they sync and how much you can customise the mapping.
Best for: simple, standard use cases with low data volume
No-code automation (Zapier / Make)
Tools like Zapier and Make connect Xero and Brevo with visual workflows. Great for getting started fast and for moderate volumes, though per-task pricing and rate limits can add up, and complex logic gets hard to maintain.
Best for: moderate volume and quick wins without engineering
Custom API integration
A bespoke integration built directly against the Xero and Brevo APIs gives you full control: exact field mapping, custom business logic, real-time webhooks, error handling and retries. This is what Ikaroa builds for business-critical syncs that need to be reliable at scale.
Best for: high volume, real-time, business-critical syncs and custom logic

Xero to Brevo integration FAQ
How do I connect Xero to Brevo?
There are three main ways to connect Xero to Brevo: a native integration (if available), a no-code automation tool like Zapier or Make, or a custom API integration built against the Xero and Brevo APIs. For occasional, simple syncs a no-code tool is fine; for reliable, high-volume or real-time syncing of invoices and bills, a custom integration is best. Ikaroa can build and manage it for you.
Can I sync Xero and Brevo in real time?
Yes. Using webhooks from Xero, changes can be pushed to Brevo within seconds instead of waiting for a scheduled batch. Real-time syncing is best handled with a custom API integration, which Ikaroa builds with proper retries and error handling so nothing is lost.
What data can I sync between Xero and Brevo?
Commonly synced data includes invoices, bills, contacts and transactions. The exact fields depend on your setup. Ikaroa maps your Xero data to the right objects in Brevo and handles any transformations needed in between.
Do I need Zapier to integrate Xero with Brevo?
No. Zapier or Make are convenient for simple automations, but they are not required. A direct, custom Xero to Brevo API integration avoids per-task fees and rate limits, and gives you more control over reliability and logic. Ikaroa builds both no-code and custom integrations depending on what fits your needs.
How much does a Xero to Brevo integration cost?
It depends on complexity: a simple one-way sync of invoices and bills is far cheaper than a real-time, two-way integration with custom logic. Ikaroa scopes the work up front and gives you a fixed quote. Get in touch for a tailored estimate for your Xero → Brevo integration.
Is the Xero Brevo integration secure?
Yes. We connect to Xero and Brevo using their official APIs with OAuth or scoped API keys, never store credentials in plaintext, and follow least-privilege access. All data in transit is encrypted, and we can host the integration in your own cloud if required.
