Billing & Plans

Upgrading Your Plan

Learn how to upgrade, downgrade, or switch billing frequency between Koji's Free, Insights, Interviews, and Enterprise plans.

Changing Your Koji Plan

Koji makes it easy to move between plans as your research needs evolve. Whether you're upgrading for more credits, downgrading to save costs, or switching between monthly and annual billing, here's how it works.

How to Upgrade

From Free to a Paid Plan

  1. Navigate to your Dashboard
  2. Click on Upgrade or visit the Pricing page
  3. Select your desired plan (Insights or Interviews)
  4. Choose monthly or annual billing
  5. Complete checkout via Stripe
  6. Your new credits are available immediately

From Insights to Interviews

  1. Go to Account SettingsBilling
  2. Click Change Plan or access the Stripe billing portal
  3. Select the Interviews plan
  4. The upgrade takes effect immediately
  5. You'll receive a prorated credit for unused time on your current plan

Upgrading to Enterprise

Enterprise plans are custom-negotiated. Contact the Koji team to discuss your needs:

  • Volume-based credit allocations (500+ credits/month)
  • Dedicated success manager
  • Custom integrations and SLAs

How Proration Works

When you upgrade mid-billing cycle:

  1. Immediate access — you get the new plan's features and credits right away
  2. Prorated charge — you're charged only for the remaining days in your current billing period at the new plan's rate
  3. Prorated credit — you receive a credit for the unused days on your previous plan

Example: If you upgrade from Insights (€29/mo) to Interviews (€79/mo) halfway through your billing period:

  • You receive a ~€14.50 credit for the unused half of Insights
  • You're charged ~€39.50 for the remaining half on Interviews
  • Net charge: ~€25 for the remainder of the period
  • Next full billing period: €79

How to Downgrade

From a Paid Plan to Free

  1. Go to Account SettingsBilling
  2. Click Cancel Subscription or access the Stripe billing portal
  3. Your paid plan remains active until the end of your current billing period
  4. After that, you revert to the Free plan

From Interviews to Insights

  1. Access the Stripe billing portal from your Account Settings
  2. Select the Insights plan
  3. The change takes effect at the end of your current billing period
  4. You retain full Interviews features until then

What Happens to Your Data on Downgrade

Nothing is deleted. All your data is preserved:

  • ✅ Studies remain intact (but may be paused if over the study limit)
  • ✅ All interview transcripts and responses are kept
  • ✅ Reports remain accessible
  • ✅ Settings and configurations are preserved

If you downgrade to a plan with a lower study limit (e.g., Interviews → Insights limits you to 5 active studies), studies beyond the limit will be paused. You can choose which ones to keep active.

Frequently Asked Questions

Will I lose my data if I downgrade?

No. All studies, interviews, transcripts, and reports are preserved. Some studies may be paused if you exceed the lower plan's study limit.

Can I upgrade in the middle of a billing cycle?

Yes. Upgrades take effect immediately with prorated billing. You only pay the difference for the remaining days.

How do I cancel my subscription?

Access the Stripe billing portal from Account Settings → Billing. Your plan stays active until the end of the current period.
