When you link accounts using the Premium plan, all of the transactions you make in real life will get automatically imported into your budget.
If you also use Goodbudget’s scheduling feature, you may inadvertently create duplicate transactions since Goodbudget currently cannot match your automatically-imported transactions with your existing ones.
To avoid that, be sure to delete any scheduled transactions that are associated with a linked account. Alternatively, if you’d like to keep your scheduled transactions so that you get your email reminders, or for some other reason, be sure to delete them after they post.
