Connect Slack from Integrations to send renewal and document alerts in the ClearSpend app in Slack as well as email. Message content matches Subscription notifications.

​
Who can connect

Members, Admins, and Owners can connect Slack from Integrations.

​
Connect Slack

1

Open Integrations

Go to Manage → Integrations in the sidebar.
2

Find Slack

Locate the Slack card in the integration list.
3

Click Connect

ClearSpend redirects you to Slack’s authorization screen. Review the permissions Slack requests for your workspace.
4

Approve

Approve the installation. You are redirected back to ClearSpend with a success confirmation when the connection completes.

​
One Slack workspace per ClearSpend org

Each Slack workspace can connect to one ClearSpend organization only. If you try to connect the same Slack workspace to a second org, ClearSpend blocks it.

​
Who gets Slack messages

When Slack is connected, alerts appear in the ClearSpend app in Slack. Who sees each alert depends on the notification type: Recipients only see alerts that apply to them. Invoice recipients do not need a ClearSpend account — they can respond from the Slack message or upload link.

​
What you receive in Slack

Examples (see screenshots on the Slack notifications page):
  • Upcoming subscription renewals — table with days until due
  • Monthly renewal digest — upcoming renewals for the month with vendor, amount, and owner
  • Invoice upload request — when someone uses Request invoice or Request missing invoices on Transactions
Each message includes a button back to the app (for example Manage subscriptions or Upload Invoice).
ClearSpend Slack notifications for invoices and renewals

Slack notifications: invoice upload requests and upcoming subscription renewals reminders.

​
Send documents from Slack

You can add invoices and receipts to ClearSpend without leaving Slack. Upload a file in a channel where the ClearSpend app is added — ClearSpend imports it into your workspace the same way as an email or manual upload. Supported file types include PDF, JPG, PNG, and CSV. Imported files appear in Documents for matching and review.

​
Email settings still apply

Configure email timing and recipients under Settings → Notifications: reminder days (1, 3, 7, 15) and extra email recipients. Slack mirrors eligible notifications in parallel; it does not replace email unless you turn email off.

​
Disconnect

Admins and Owners can disconnect from Integrations → Slack. You can also remove or reinstall the app from Slack’s app management if your admin policy requires it.
