Welp, after 3 weeks of being in MP there's both good and bad compared to "the old way". Some of the dissatisfaction is simply adjusting to new methods and workflows. Me no likey change.
In no particular order:
Having to wait almost a week before having access to funds is annoying (if you use daily payouts; if you do weekly, it could be 10+ days depending on when purchases are paid).
This is mitigated somewhat by being able to pay for shipping labels out of pending funds. However, unlike PayPal you can't choose to leave any funds there for future shipping labels; when your scheduled payout day hits, the entire balance is emptied. If there's a way to leave an $X reserve, I've not found it. This means you have to have a backup funding method in place, which defaults to PayPal... but since there's no longer money going into Paypal, that's a bit useless for many people. I have it set to a debit card that pulls from the very bank account that
ebay dumps into. The only downside being if you're a low-to-medium volume seller or hit a lull, you could need to pay for shipping labels during periods where your funds are "processing" or the 3-4 business days between when they leave your
ebay balance (where they would have been "available" to use for shipping labels), and when the money finally hits your account. For low-volume sellers I would recommend making a credit card your backup funding source if you're not sure you'll maintain a reserve balance in that bank account.
There's currently no way to pay your monthly store subscription fee from available funds in the way you can pay for shipping labels, which is absolutely idiotic. You HAVE to pay monthly store subscription fees using an external payment method. Supposedly this feature is coming, but who knows when.
I like having all of the final value and payment fees removed before I see any money rather than having to pay up at the end of the month. Previously under PayPal, when I had a good month without realizing it, I might be surprised by an unusually high
ebay fee bill at the end of the month; this removes that possibility. YMMV as to whether this model fits your preference.
The total FVF + payment fees *ARE* higher under managed payments than PayPal depending on what categories you sell in and what percentage of your sales are international.
The dashboards are a bit discombobulated, resulting in you having to look all over the place depending on what granular bit of information you're looking for.
The .CSV reports are utter garbage compared to those provided by PayPal. I want to slap whoever came up with their report formatting.
The fact that granular transaction reports are still only available for 90 days is highly disturbing. At minimum they should go back one full calendar year, one could argue longer. I've set myself a calendar appointment for the 5th of every month to download the transaction report from the prior month. People who wait to the end of the calendar year to pull information for doing taxes are in for a rude awakening... and given that more and more states are DRASTICALLY lowering the threshold for 1099-K reporting to the IRS, I'm guessing that more than a few casual sellers are scrambling when they didn't plan to...
In a nutshell: It shows promise as being a streamlined integrated payment & order processing workflow, but in typical
ebay fashion, what they've thrown out there is still somewhat of a hacked up mess.
