SAKU Thanks Custom: The differences between the Free and Pro plans, and how to change plans

This article explains the differences between the "SAKU Thanks Custom" plans (Free and Pro) and how to change your plan. (A Partner development store is a free store that app developers and others create for testing. A store that sells normally is not one of these.)

In this article

• What you can and can't do on the Free and Pro plans
• Where to check your plan in the app
• How to subscribe to or change to the Pro plan
• How it works on Partner development stores
• What happens when you go back from the Pro plan to the Free plan

Where to go: Shopify admin → Apps → "SAKU Thanks Custom" → "Pricing" in the left menu

Prices and plans

The prices above are as listed on the Shopify App Store (as of October 2026). All charges are billed in US dollars (USD). The final amount is shown on Shopify's plan selection screen. Partner development stores are free.

Plan comparison

Text, image, custom HTML and recommended products blocks are available on the Free plan too. The Pro plan adds the full set of email list growth features (reward coupons, the subscribe checkbox, Flow email delivery and the signup counter). On the Free plan, you can open the admin and use the basic features without any billing step.

1️⃣ Check your current plan

On the right side of Home is a card called "Plan". It's the middle one of the three cards stacked on the right ("About this app", "Plan" and "Support").

• Partner development stores: a "Free" badge and "Free on development stores" are shown.
• Live stores: an "Active" badge, the plan name (the name Shopify returns, or "Free plan" if there isn't one) and a "Change plan" link are shown.
• Live stores that aren't on a paid plan also see "The coupon block is available on the Pro plan ($4.99 / month)."

The number of steps in the setup guide also depends on your plan: 2 on the Free plan, and 4 on the Pro plan and on development stores.

2️⃣ Open the "Pricing" page

Open "Pricing" in the app's left menu. The page heading is "Plan", and you can go back from "Home" at the top left.

(The image shows a development store. On live stores, the text and button described under "On live stores…" below are shown.)

• On Partner development stores, an info banner shows "Free on development stores" and "Partner development stores can use every feature without approving a subscription."
• On live stores, it says: "The Free plan covers Thank-you-page customization: text, image, custom HTML, and recommended-product blocks. The Pro plan ($4.99 / month) adds the newsletter-growth engine: the coupon reward, the opt-in checkbox, Flow email delivery, and the subscriber counter."
• The "Choose a plan" card says "Subscribe to a paid plan — or change your current plan — on Shopify's secure pricing page." and has a "View plans" button.
• Press "Back to dashboard" to go back to Home.

3️⃣ Subscribe to the Pro plan or change your plan

Press "View plans". Shopify's own pricing page opens (it's separate from the app's screens). The Free plan and the Pro plan are shown side by side. The Pro plan is $4.99/month or $49.90/year. Follow the instructions on the screen to choose a plan.

To cancel the Pro plan and go back to the Free plan, use the same "View plans" button and choose the Free plan. (If Shopify's screen looks different, follow the instructions on the screen.)

The Pro plan comes with a 7-day free trial. Check the final amount and trial period on Shopify's pricing page.

If the pricing page doesn't open, "The pricing page is temporarily unavailable. Please reload and try again." appears. Reload the page and try again.

When you change your plan, Shopify notifies the app and the change takes effect right away. The app also checks your plan again every time you open its admin screen.

4️⃣ When you try to use Pro features on the Free plan

If you try to use a Pro feature (coupons) while on the Free plan, this happens:

• Pressing "Coupon" under "Choose block type" takes you to the Pricing page. Opening the URL directly also takes you to the Pricing page.
• If you already have 2 blocks and save a third, you get the error "The Free plan allows up to 2 blocks. Upgrade to the Pro plan from the Pricing page to create more." (on the Pro plan and development stores, the message is "You can create up to 30 blocks.").
• The "Blocks" page always shows the banner "Free plan: up to 2 blocks are shown".

5️⃣ Using a Partner development store

On Partner development stores, you can use every feature without approving a subscription. Coupons are available, and they're issued for test orders too. You can create up to 30 blocks.

If a development store moves to a paid Shopify plan, the app automatically re-checks it and treats it as a live store.

6️⃣ When you go back from the Pro plan to the Free plan

• Coupon blocks are no longer shown on buyers' Thank you pages, and no new codes are issued.
• On the "Blocks" page, you can only "Disable" and "Delete" coupon blocks. Pressing "Enable" or "Duplicate" shows "The coupon block requires the Pro plan. Open Pricing to upgrade." Opening "Edit" on a coupon takes you to the Pricing page.
• If you have more than 2 blocks, none are deleted. Only the first 2 "Active" blocks are shown, and the rest get a "Not shown (Free plan)" badge.
• The order status page block keeps showing codes that were already issued.

After the change

After changing your plan, reopen the app's Home, and the "Plan" card and the number of setup guide steps change. When you subscribe to the Pro plan, the guide has 4 steps, you can create up to 30 blocks, and up to 30 blocks are shown on the Thank you page.

Troubleshooting

• I subscribed, but I can't use coupons
  Reopen the app's Home. Your plan is updated by Shopify's notification and by the check that runs every time you open the admin screen. If that doesn't fix it, get in touch through "Contact support".
• The plan name still says "Free plan" / a different name is shown
  The plan name is shown exactly as Shopify returns it. If there's an active subscription, it's treated as paid unless the plan name is "無料" or "Free".
• When your store's API is temporarily unavailable
  The app uses the plan information it saved earlier (paying customers are never locked out). If loading fails right after installation, the store is treated as "not subscribed", and coupons can't be used until the plan is loaded successfully. Wait a while and reopen the app.
• I'm asked to pay on a Partner development store
  Partner development stores can be used without approving a subscription. A store that has moved to a paid Shopify plan is treated as a live store.
• I want to know how long the free trial is
  The Pro plan comes with a 7-day free trial. The final details are shown on Shopify's pricing page.
