I have hundreds of very tiny cash-sales’ transactions and need to import them.
Why? Because most people use custom billing managers or payment gateways e.g. Stripe, Paypal. These gateways support exporting transactions in CSV, QIF, etc.
@Tut: I don’t know how many people are actually migrating to the Manager but ability to import all stuff, including cash sales would help your conversion rates from existing accounting platforms.
Also, going through the forum I see “Batch import” is the single most requested feature so the Manager should expose some sort of API for developers to deal with it.
