You can edit a live subscription to update pricing, change tax rates, and add or remove discounts without cancelling and recreating it.
This article explains how to open the pricing editor, preview your changes, and choose when the update should take effect.
👤 You'll need permission to manage the subscription to make any of the changes in this guide.
What you can change
From the subscription pricing editor, you can:
Change a unit type
Add or remove units, insurance or products
Change quantities
Set a custom price
Change the tax rate on a line item
Add, change or remove discounts
All changes are reviewed in a preview before you save them.
How to open the pricing editor
Open the subscription you want to update.
In the Pricing section, click Edit subscription.
A pricing editor will open with all line items shown together, including units, insurance and products.
How to change a unit type or price
You can update a unit line item if the customer is moving to a different unit type or if you need to adjust the price.
In the pricing editor, find the unit line item you want to change.
Select a different Unit type if needed.
Update the quantity if the customer needs more than one of the same unit type.
Adjust the price if you need to apply a custom amount.
Review the preview before saving so you can confirm the final charge.
How to change the tax on a line item
Each line item uses a tax rate from your site’s tax settings.
In the pricing editor, find the line item you want to update.
Choose the correct Tax rate.
Repeat for any other line items that need to change.
💡 You can only choose from tax rates already set up for the site. If the rate you need is missing, add it in your tax settings first.
How to add, change or remove a discount
You can apply a discount to either:
A single line item, such as one unit or product
The whole subscription, using a global discount
To update a discount:
Open the pricing editor.
Choose the line item discount or subscription-wide discount you want to apply.
To remove a discount, clear the current selection.
Continue to the preview before saving.
💡 Discounts that have expired or been removed can no longer be re-added to a subscription.
How to preview the change
Nothing is saved until you preview and confirm the update.
Click Preview changes.
Review the before-and-after summary.
Check the updated totals, including tax, discounts and any prorated charges.
If something does not look right, go back and adjust it before saving.
Choose when the change takes effect
If the subscription has already started, you can choose when the change should apply:
Immediately: the change takes effect now
On next renewal: the change starts from the next billing date
Backdate: the change applies from a date in the past
If you backdate a change, you can choose any date between the subscription’s last billing date and yesterday.
💡 If you are unsure which option to use, choose On next renewal. It is usually the simplest option because the new pricing starts from the next invoice without part-period adjustments.
Understanding prorations
If you apply a change immediately or backdate it, Stora may calculate a proration.
A proration is a part-period charge or credit that adjusts for the difference between the old pricing and the new pricing during the current billing period.
For example:
A customer is halfway through the month
You add another unit and apply the change immediately
The customer is charged only for the remaining part of the month for that extra unit
The preview shows any prorated amount before you save.
If you choose On next renewal, the new pricing starts from the next invoice and no proration is created.
What causes a proration — and what doesn't
Applies when the change is set to take effect immediately or backdated:
Change | Proration? |
Adding or removing a unit, insurance or product | ✅ Yes |
Changing the price on an item | ✅ Yes |
Changing the quantity of an item | ✅ Yes |
Changing the tax rate on an item | ✅ Yes |
Adding, changing or removing a discount (on its own) | ❌ No |
Any change applied on next renewal | ❌ No |
A note on discounts and prorations
A discount change on its own does not create a proration. It applies to future charges only.
However, if you change a discount at the same time as a price, quantity or tax change, the discount may be included in the prorated charge. This can make the discount take effect earlier than expected.
For example, a discount you intended to start on the next invoice may be applied to the part-period charge instead.
💡 To keep billing clearer, it is usually best to change discounts separately from price, quantity or tax changes.
Always check the preview before saving so you can confirm exactly what the customer will be charged and when.
FAQ
Can I change the price on lots of subscriptions at once?
No. This editor works on one subscription at a time. For scheduled increases across many subscriptions, use Price increases.
I can’t find the tax rate I need.
You can only choose from the tax rates set up for your site. Add the missing rate in your tax settings, then return to the subscription.
Why can’t I re-add a discount?
Expired or removed discounts cannot be re-applied to a subscription.
I applied a change immediately, but the customer has not been charged yet. Why?
Not every immediate change creates an immediate charge. For example, a discount change on its own applies to future invoices. Check the preview to see when the next charge will happen.
My discount started earlier than I expected. Why?
This usually happens when the discount was changed in the same edit as a price, quantity or tax update. In that case, it can be included in the prorated charge.
How far back can I backdate a change?
You can backdate to any date between the subscription’s last billing date and yesterday.
Will the customer see the change?
Yes. The updated pricing will be reflected on invoices from the point the change takes effect.
Key benefits
Editing tax
You can now change tax rates — before, tax was locked in at booking with no way to change it on a live subscription.
Fix the wrong tax rate without cancelling anything — no more cancel-and-rebook or editing in Stripe just to correct a rate.
Handle business (B2B) customers properly — set the right tax treatment for a company even when the storefront only offers the standard consumer rate.
No stale tax hanging around — retired tax rates are flagged so you're prompted to swap them for a current one.
You choose from your real rates — pick from the rates set up for your site, so you can't accidentally type the wrong percentage.
Put it right from the right date — backdate the correction to when it should have applied, or set it for the next renewal.
Editing discounts
Add or remove a discount whenever you need to — apply a promotion or loyalty discount to a live subscription, or take one off, without rebuilding the booking.
Discount one thing or everything — reduce the price of a single item (e.g. one unit) or apply one discount across the whole subscription.
See the new price before you commit — the preview shows exactly what the customer will pay with the discount applied.
No re-adding expired offers by mistake — discounts that are no longer valid can't be re-applied.
One clean change on the bill — discounts, tax and any other edits go through together, so the customer sees a single tidy adjustment rather than several.
