Hi Tomas, If you have created your form in Google forms, then you can customize it using the Neartail addon to calculate the amount and collect payments. Calculate order amount Open your form in Google Forms > click on the addon icon > click Neartail > click Calculate order amount > select the currency, click Next > select Fixed amount option, enter the amount (OR) calculate amount based on the price option and click Proceed > Neartail Edit page will open in a new tab. Enable payments In the Neartail Edit page, click on the gear icon next to the Submit button > Button settings will be displayed > click Enable payments > The payment options supported in your country will be displayed > configure the preferred payment methods and click Save > You can then use the Neartail share link to collect responses. When the user makes the payment and submits the form, the responses will be recorded in Neartail and Google Forms. You can sync the Google Forms responses to Google Sheets. Please note that the payment details will not be included in sheets linked with Google Forms. If you enable automated payments such as card via Stripe or Paypal, users will be able to submit the response only if the payment is successful.
