Leveling up with Lebak
The starting point
Lebak is accounting software that complies with French rules: chart of accounts, VAT, FEC export. It needed an app to handle anything awaiting a response in a few seconds.
The challenge
Keep a single accounting source of truth: the app never writes directly. It sends decisions that a server function replays on the latest version of the books, even if the web app is saving at the same moment.
Challenge met
Business owners approve their transactions and see their real cash position from their iPhone, on the same books and with the same rules as lebak.fr.
