Short answers to the questions merchants ask most. Each links to the full article where there is one.

<details>
<summary>Do you take a percentage of what my offers earn?</summary>

No. Every plan is one flat monthly price. What your offers earn only decides which plan you need. See [Choose a plan](https://help.attravo.com/post-purchase-upsell/articles/choose-a-plan.md).

</details>

<details>
<summary>Who charges me for Attravo?</summary>

Shopify does. Your plan appears on your Shopify invoice, billed in USD, and you change it in your store admin. Attravo never sees a card number.

</details>

<details>
<summary>Does it work with cash on delivery?</summary>

Yes, on the thank you and order status pages: the item joins the order and the courier collects the new total. The post-purchase page is never shown for cash on delivery orders.

</details>

<details>
<summary>Do customers have to pay again or enter their card?</summary>

On the post-purchase page, their card is charged in one tap. On the thank you and order status pages, a paid order gets an invoice email for the difference, and cash on delivery orders pay the courier.

</details>

<details>
<summary>Can a customer see the same offer twice?</summary>

Not once they have answered it: an answered offer is not shown again, and a funnel that has finished never shows again on that order. An offer they have not answered yet is still there when they come back to the order status page.

</details>

<details>
<summary>Do I need Shopify Plus?</summary>

Only for offers inside checkout itself. The post-purchase, thank you and order status pages, and the page blocks, do not need Plus.

</details>

<details>
<summary>Will Attravo slow down my store?</summary>

Core Script, the app embed, runs once a day per visitor's browser, when the page is idle, and draws nothing. Offers load on the checkout pages, not your storefront.

</details>

<details>
<summary>What does Attravo store about my customers?</summary>

Order numbers and totals, payment and fulfilment status, and which offers were shown and answered. A customer's first name is read from the order when an offer needs it and is not stored.

</details>

<details>
<summary>Do test orders count in my results?</summary>

Yes. A test order that takes an offer counts like any other order once it is paid, so expect it in Performance.

</details>

<details>
<summary>Can I change the offer's colours and fonts?</summary>

Offers use your checkout's branding, set in the checkout editor. See [Match your store's look](https://help.attravo.com/post-purchase-upsell/articles/match-your-store-design.md).

</details>

<details>
<summary>Which languages does Attravo support?</summary>

The admin is in English and French. Offers can be translated into any language your customers use, on Scale and Enterprise. See [Translate your offers](https://help.attravo.com/post-purchase-upsell/articles/translate-your-offers.md).

</details>

<details>
<summary>How do I tell which orders took an offer?</summary>

They are tagged **Attravo upsell** and with the funnel's name, so you can filter them under **Orders** in your Shopify admin. **Recent orders** on Performance lists them too.

</details>

<details>
<summary>How do I get help?</summary>

Email support@attravo.io and a person replies, or book a free call at https://calendly.com/attravo/discovery. Both are on Home under **Help and support**.
