Sell Units on TtaKkaa: Sell the Same Item by Piece, Pack, and Carton Without Duplicating It
Picture a supermarket selling bottled water: a customer might buy a single bottle, a pack of 6, or a carton of 24. Without a sell-units system, the owner would have to register "Water - bottle," "Water - pack of 6," and "Water - carton of 24" as three completely separate items, which clutters inventory and reports. TtaKkaa solves this with sell units.
The problem: the same product, different ways to sell it
Simple systems make the owner register every way of selling as a separate item with a separate stock balance, so selling a carton has no automatic link to the single-bottle balance, and the owner has to update both manually — which causes stock drift over time.
How TtaKkaa solves it
With TtaKkaa, you register the product once with a base unit (a single bottle, for example), and add extra sell units to it:
- A "pack of 6 bottles" unit — conversion factor of 6 relative to the base unit.
- A "carton of 24 bottles" unit — conversion factor of 24.
When the cashier sells a carton, the system deducts 24 bottles from the base unit stock automatically, with no manual calculation.
A different price for each unit
Each sell unit has its own price, not necessarily an exact multiple of the base unit price — so you can offer a small discount on the carton to encourage bulk buying, a pricing decision you make, not a rigid automatic calculation.
An example from a grocery store
A grocery store sells rice by the kilo and by the 25kg sack. Instead of registering "rice kilo" and "rice sack" as two separate items, it registers one item with two sell units, each with its own price, and stock is tracked accurately with no duplication.
The same experience for the customer in the app
A customer ordering from the TtaKkaa app sees the available sell units for the same product and picks the one they need (piece, pack, or carton) before confirming their order.
The numbers, honestly
Instead of a duplicate item for every way of selling, you get one product with its units, keeping inventory accurate and reports clear without clutter.

Does stock count correctly if I sell by carton instead of by piece?
Yes. Each sell unit has a conversion factor to the base unit, so selling one carton of 24 pieces deducts 24 pieces from the base stock automatically.
Do I need to set a separate price for each sell unit?
Yes, each sell unit (piece, pack, carton) has its own price, not necessarily an exact multiple of the base unit price, so you can offer a discount on the larger quantity.
Does a customer ordering from the app see these sell units too?
Yes, the customer can pick the unit they want (piece or pack) from the same product screen in the app.
