Add-ons
Add-ons raise one limit of your plan without moving to a bigger plan. They are added to a paid plan only: on the Free plan, or during the free month before you pick a plan, the Add-ons section says “Pick a plan below first.”
What you can add
| Add-on | Price per month | How many |
|---|---|---|
| One more store | $3 each | Up to 20 |
| 90 days of history | $4 | One history at a time |
| 180 days of history | $6 | One history at a time |
| 365 days of history | $8 to $60, by volume (see below) | One history at a time |
| 80 more AI requests a month | $7 each | Up to 20 blocks |
The 365-day history costs more on bigger volumes, because more visits are kept:
| Visits per month | 365 days of history |
|---|---|
| 5,000 | $8 |
| 25,000 | $9 |
| 50,000 | $18 |
| 100,000 | $25 |
| 250,000 | $60 |
A history add-on must be longer than the history your plan already keeps, so Whence only offers the longer ones: 90 days on plans that keep 60 days (the 5,000 visits volume), 180 days on plans that keep 60 or 90 days, and 365 days on every paid plan.
On a yearly plan, each add-on costs twelve times its monthly price. The 20 percent yearly discount applies to the plan, not to add-ons.
The AI block add-on gives you 80 more AI requests every month, for as long as you keep it. If you only need more AI now and then, AI top-ups add requests only in the months you run out.
Change add-ons in the web app (card payment)
Step 1: Open Plan
In the Whence web app, open the account menu at the top left, then Plan. The Add-ons section is below your current plan.
Step 2: Pick what you want
Use + and − next to One more store (1) and 80 more AI requests a month. Under Longer history (2), choose a history, or keep the first choice, your plan’s own history (for example “60 days (plan)”). Then click Review new total (3).
Step 3: Review the total and confirm
Whence shows your plan, each add-on and the New total (1), per month or per year, with this line: “Stripe charges or credits the difference for the days left.” Click Confirm add-ons (2). You see “Add-ons updated.” Nothing changes at Stripe before you confirm.
To remove an add-on, set it back to zero (or pick the plan’s own history) and confirm the same way.
Change add-ons in the Shopify app
If Shopify bills your plan, the web app shows: “Your plan is billed by Shopify. Change add-ons in the Whence app in your Shopify admin (Apps, Whence, Plan).” There, click Add-ons, make your changes and click Review new total. Shopify then opens a page where you approve the new total. Add-ons are billed by Shopify with your plan.
When you change plans
Your add-ons move with you. The new plan’s price is calculated with the add-ons you already have. A history add-on that your new plan no longer needs (because the plan keeps as much history) is dropped.
Messages you may see
- “You have 3 active stores. Pause a store in Whence before going under 3 stores.” (Shopify app) You tried to remove store add-ons while those stores are still active. Pause a store under Stores first.
- “Add-ons are added to a paid plan. Choose a plan first.” (Shopify app) Pick a paid plan, then add.
- “The add-ons could not be priced. Try again.” A temporary error. Try again in a moment; if it persists, contact support.
