Each proposal needs a number of connects. Most of the jobs need 2 connects for per proposal. If you don't have connects you need to buy them using your cards, or if you have balance in upwork you can also buy connects. If you have a free membership you will get 10 connects free in every month.
Uththara glad to see you here
actually, you need to buy Connects from Upwork or you should wait for your Connect Cycle month. every month you will get 10 Connects per month, but it's better if you buy connects from Upwork and get Plus membership to get Jobs and showing your Profile in the listing...
if you have any further question, you can feel free ask us
Thank You & Good Luck
If you need more Connects to submit proposals, you may purchase them from your account. To purchase Connects, you will need to add a billing method on file. This can vary based on your location, but all Upwork users will be able to purchase Connects with a credit card or prepaid card. If you aren’t able to use a credit card or prepaid card or you don’t have an Upwork balance, in many cases you’ll be able to use PayPal. To see the options available to you, click here.
