Haven't seen an increase in sales, but have had direct checkout sales.
This was a note from Etsy on top of the invoice page, on my most recent sale, so just beware.
'Great news! Based on your sales history, going forward, funds for your direct checkout orders will become available for deposit to your bank account the next business day after the order is placed. Deposits will occur on Mondays, or sooner if you click "Schedule an Earlier Deposit".'
Sounds like they are going to automatically deposit my sale monies the next day based on my history, right? The sale was Tuesday, when I went to check to see if the sale money was deposited just now, It said it would be deposited the 13th, next Monday. Well, so much for good history.
However, I was able to reschedule to tomorrow for the deposit, but, had I not checked the details out today and depending on the sale to be deposited today, my deposit would not have been made until the next Monday even though they said because of my history they are going to deposit the next day after a sale.
When I first got the sale and checked etsy's deposit info, it actually did say it would be deposited on the 8th. Somehow though, they changed it to the 13th, the first Monday after the sale.
What I am saying is 'keep on top of your sales and your Etsy deposits info to your checking account. Make sure they are happening as Etsy says they will.
Their wording in their paragraph above from the top of my invoice page, is a little vague, I think.
Aside from that, I like direct checkout to add another way to pay for the customer. It might just mean a sale that might not have happened otherwise, and the Paypal choice is still there as a paying option, along with the credit card choices, not real prominent, but its there.
