I live in Ireland. I am just about to setup a Shopify store, mainly selling in the US using Facebook Ads. I would like to know the answer to one question:
To directly answer the question and example; the funds would be transferred to your bank on the following Monday if the order came in on Wednesday. When using Shopify Payments in Ireland, you will see your payouts transferred in 3 business days. The transfer process is when we send the funds, and would not include the processing time your bank may add; however, most banks will deposit your funds within 24-48 hours of receiving the funds. It's important to note that funds will not be transferred on the weekend, or public holidays (includes holidays from where the funds are being transferred from, and where they are being transferred to). In addition, 3 business days only applies to Shopify Payments as other payment providers may have different payout schedules. If you are not using Shopify Payments then you will want to reach out to your payment provider to inquire about their payout schedule.
May I ask what brought you to need a $700/week budget for marketing when you're just starting out? Have you considered how to increase your organic reach before investing in paid ads?
