Connecting Salesforce to Xero, Mailchimp and Microsoft 365: A Practical Guide for UK Charities

If you're using Salesforce as your CRM but still manually copying data across to Xero, Mailchimp or Outlook, you'll know exactly how frustrating — and error-prone — that can be. Staff enter the same contact twice, financial records don't match your CRM, and email lists drift out of date.

The good news is that Salesforce integrates well with all three of these tools. Here's a plain-English overview of what's possible and what to consider.

Salesforce and Xero: keeping your financial data aligned

For charities managing donations, grants, and restricted funds, having your CRM and accounts talk to each other is genuinely transformative. A Salesforce–Xero integration means:

• Donation records in Salesforce can automatically create invoices or payments in Xero

• Financial data flows without manual re-entry, reducing errors

• Reconciliation becomes much faster — your fundraising team and finance team are finally looking at the same numbers

There are several integration tools available to connect the two platforms, and the right choice depends on your transaction volume, the complexity of your chart of accounts, and how your restricted funding is structured. This is an area where getting specialist advice really pays off — a badly configured integration creates more problems than it solves.

Salesforce and Mailchimp: smarter supporter communications

Mailchimp is popular with charities for good reason — it's accessible, affordable, and easy to use. But when it's disconnected from your CRM, you end up with audience lists that don't reflect your actual supporter data.

Connecting Salesforce and Mailchimp allows you to:

• Sync contacts and segment your audiences based on real CRM data (donor history, engagement level, programme involvement, etc.)

• Automatically add new supporters to the right Mailchimp audience when they're added in Salesforce

• Feed email engagement data back into Salesforce so you can see who's opening, clicking, and engaging

Salesforce offers a native Mailchimp connector, and there are third-party tools too. For most charities, a well-configured native sync is sufficient — you don't need complex middleware.

Salesforce and Microsoft 365: connecting your day-to-day work

Most UK charity teams live in Microsoft 365 — Outlook, Teams, SharePoint, Word. Salesforce has solid integrations with the M365 suite:

• Salesforce for Outlook (or the newer Salesforce Inbox) lets staff log emails, create contacts, and update records directly from their inbox

• Microsoft Teams can surface Salesforce records and notifications without switching apps

• SharePoint can be linked to Salesforce for document management — useful for storing grant agreements, contracts, and case files alongside the relevant Salesforce record

These integrations reduce context-switching and make it far more likely that your team will actually keep Salesforce up to date — because it fits into how they already work.

A word on integration strategy

It's tempting to connect everything at once. Our advice: start with the integration that will save the most time or cause the least pain if it goes wrong. Get that right, then build from there. And always make sure you understand what data is flowing in which direction — and who owns it.
