# Why are memberships not getting activated after membership sale tasks are added to an invoice?

## Problem

You added a membership sale task to an invoice, but that did not activate a membership as it should have.

## Solution

#### Correct the workflow for membership activation

1. Go to **Pricebook**.
2. Search the service task that should activate the membership.
3. In the **workflow** tab, make sure to select *Create and activate membership plan*.
4. Save the changes.

#### If the invoice has not been exported

1. Go to the invoice where the membership sale task is added.
2. Delete the incorrectly set up task.
3. Add the task again to trigger the membership activation.

#### If the invoice has been exported

1. Because the invoice was already exported to your accounting software, you need to zero out the invoice with the inaccurate membership sale task:
  1. Create an adjustment invoice.
  2. Add a dummy service task which does not have a workflow enabled in Pricebook. Make sure the quantity set is negative. This will zero out the invoice.
  3. Unapply the payment so you can apply it to the right invoice afterward.
2. Sell a membership to the customer:
  1. Go to the customer's page.
  2. Select **Sell Membership**.
  3. Choose the correct membership sale task to apply without creating a new job.
  4. You can now apply the unapplied payment to this invoice.
