A July–June year, and an NBR registration gate that is not a development task.
Bangladesh's export manufacturing is dominated by ready-made garments, which is discrete, order-driven production with heavy subcontracting — the shape Rebota handles well. Two things stand in the way, and only one of them is code. The financial year runs 1 July to 30 June, which Rebota resolves per company without difficulty. The harder one is that VAT software must be registered with the NBR before it can be used for Mushak 6.3 compliance. That is a regulatory approval, not a feature: no amount of development substitutes for going through it, and Rebota has not.
