Source and destination wallets
A transfer has a source wallet and a destination wallet. One balance decreases and the other increases. Combined net worth changes only because of a fee or exchange result.
Incomplete and duplicate transfers
A withdrawal without a linked deposit may be an expense or an incomplete transfer. Two copies of either side change that wallet balance twice.
Both sides of a transfer
Compare both sides by amount, wallet, currency, date, effective rate, and fee. Correct the link, and Tetri will recalculate the income and expense reports.
Transfers and exchange differences
Moving money between wallets does not create income. A currency exchange can separately create a gain, loss, or fee.
