• Proper validation of the report file.

We do not receive the proper quantities for some products (for example cutlery or ketchup). We should probably implement some kind of multiplier that can be defined on a per supplier product basis.

(We receive 100 ketchup packages in a single box).

Should we always assume it is 100?(as for now) Otherwise you can add the multiplier value on the webpage. If different suppliers have different amounts per package.

However manual filling of the multiplier amount is required to confirm the order then I guess.

[kjagiello]

No, we cannot assume that. I agree that multipliers should be configurable (defaulting to 1).
