My first import
For a lot of people, the first time importing data is a bit of a hack and an experiment. To prevent stress and frustration, please follow these tips and tricks.
Create all asset accounts first
Make sure you have asset accounts for each of your accounts. That includes savings accounts and credit cards
Do not import large batches
Start with ten transactions. Or maybe five. Don't try to import 4 years worth at once.
Map and rule
Use the mapping function and Firefly III's rules to manage data quality.
