I have some luggage sets brand new I want to sell worth about 100 bucks a set, how many can I safely sell per month without the Invoices, supplier info and etc stuff from ebay or paypal?
The complete step-by-step guide to get back to selling today!
Start out by selling one or two the first month. Increase your sales by 50%-75% per month for the first 3-4 months, then you're free to sell what you like in Paypal's view. They usually only request supplier info if they suspect you're liquidating stolen or counterfeit products. So if you slowly increase your selling pace over few months it will look like natural growth and you should be fine.
All this advice is based on operating a brand new seller account. If you're using an aged seller account then sell as many as you'd like.
how many sets per month is very very conservatively safe? like example
month 1 4 units
month 2 6 units
so on
^^ That pace would most likely do you just fine. To make it more conservative though you could do
Month 1 - 2
Month 2 - 3
Month 3 - 5
Month 4 - However many you want, because your account should be strong enough by then to have the payment holds removed.
ebay number of units safe to sell
