Best credit control software that integrates with Xero, Outlook and Microsoft Teams (2026)

Facts checked June 2026.

If your team runs on Microsoft 365, you want two things from a credit control tool: reminders that send from your own Outlook address and notifications that land in the Teams channel where your team already works. Not many tools do both natively. Here are the tools on the market in 2026 and how to compare them.

Why the Microsoft stack matters for chasing unpaid invoices

Send via Outlook email: Xero does have its own in-built reminder system, but these emails send from an @xero email address. Sending reminders from your own company domain email address is better for 3 reasons:

1. The customer immediately knows who the reminder is from.
2. The email is less likely to be spam filtered.
3. Any replies will come to you.

Integrating with Outlook is therefore important for any credit control tool you use.

Notifications in MS Teams: You probably spend a lot of your day with MS Teams open. If you pick a tool that can send notifications directly to MS Teams, you avoid having to check two systems and reduce the chance of missing something important.

So for a Microsoft-stack finance team, the tool you want does both: sends customer-facing reminders through Outlook and pushes internal notifications into Teams.

How Trove connects Xero, Outlook and Teams

Xero Trove has a native Xero integration and two-way sync. This means your Xero data is always up to date before sending emails in Trove. Trove is also a Xero 2026 Growth App, recognised for solving core issues that Xero users have.

Outlook Connect your Outlook account and Trove sends every reminder from your domain, so customers see an email from you rather than from software. Your IT admin approves this once - we’ve written a guide to granting Trove access to an Outlook mailbox that walks through it.

Replies also come back into Trove. If a customer writes “I’ll pay on the 28th”, Trove reads the reply, updates the expected payment date against the invoice in Xero, and drafts a response for you to approve.

Teams Connect Microsoft Teams to your Trove account and Trove will post your chosen notifications into your chosen channels so all team members are kept up to date.

How Kolleno connects Xero, Outlook and Teams

Xero Kolleno has a native Xero integration and a two-way sync, which means that your Xero data will also be up to date before sending email reminders to your customers.

Outlook Kolleno also allows you to connect your Outlook account so that team members can send reminders from their domain. One flag - Kolleno prices on a user basis, so if you want to add multiple Outlook email addresses to send from, the price will increase.

Teams Kolleno does not offer a standalone Microsoft Teams integration but does integrate with MIcrosoft 365 which should allow notifications into Microsoft Teams.

Which one to pick

As the pricing suggests, which platform you pick depends on the size of your business.

If you’re a UK small business on Xero and Microsoft 365, you want the Outlook-and-Teams combination without paying for an enterprise AR platform you won’t use.

If you’re a larger finance team that also needs payments, reconciliation and deep AR reporting in one system, Kolleno will be a better fit.

FAQ

Can credit control software send invoice reminders from my Outlook address?

Yes. Both Trove and Kolleno send reminders from your own email address rather than a generic app address, which helps them avoid spam filters and get a response.

Does Trove sync replies from Outlook back into Xero?

Yes. When a customer replies with a payment date, Trove updates the expected payment date against the invoice in Xero and drafts a reply for you to approve.

Is there a credit control tool for Microsoft 365 without per-seat pricing?

Trove is a flat £50/month regardless of how many invoices you chase or how many people use it, which is the main difference from the quote-on-request AR platforms.
