Once again I send asking for this, since it is really causing chaos for me and for this reason I wanted to change the system. Systems handle inventory better: You can create products by category. This in order that option 2 can be done. Inventory takeovers can be made, in order to adjust but through an option that is taken, that immediately affects the inventory module. Not through adjustments of inputs and outputs but rather taking inventories by main categories or sub-categories. Power of a general product to repack, I have ordered this update many times and it still hasn't been updated. Example: of a gallon of paint, 1/2 gallon is sold repacked, 1/4 gallon is sold, so it should be possible to create bundles of the main one and that it discharges as they are sold, that is, 1/2 gallon equals 0.5 of the main gallon. To be able to manage the prices in a box-like manner, the sales price, the minimum price and the percentage of discount that can be applied. This way you can better control the issue of discounts. To have more controls and permissions, meaning that you cannot set a sales price equal to or below the cost, that when making a discount greater than the authorized one, a user can be created to authorize this discount with a key. That you have permission from who can print, how many times you can print that you cannot reprint because that way you lose control of the documents.
