Buy, stock and sell in the right units.
Purchase in cases, hold in eaches, sell in packs — WisoBooks converts between them for you. Define units and conversion factors once and every purchase, sale and stock count stays perfectly in sync.
A purchase unit, a stock unit and a sales unit
Each item can be bought, stored and sold in whatever units make sense for your business. Suppliers ship you cases; you count singles; customers buy packs — WisoBooks keeps all three aligned.
- Define your own units of measure (each, box, kg, litre…)
- Separate purchase, stock and sales units per item
- Prices and costs expressed in the right unit
- Inventory-only feature — clean for service businesses
| Unit | Role | Factor |
|---|---|---|
| Case (12) | Purchase | × 12 |
| each | Stock | base |
| Pack (4) | Sales | × 4 |
One case of 12, followed end to end
Watch the same product move through buying, stocking and selling — each in its own unit, all reconciled to one base.

Your supplier sells in cases of 12. Enter 5 cases on the bill and WisoBooks records the purchase price per case while converting to base units behind the scenes.

Hold it by the each
On the shelf, everything is counted in single units. Quantity on hand and moving-average cost are always maintained in the base stock unit.
- Stock always stored in the base unit
- Moving-average cost per base unit
- Accurate valuation, whatever you bought in
| Item | On hand | Avg cost |
|---|---|---|

Sell it by the pack
Customers buy in packs of 4. Invoice 3 packs and WisoBooks deducts 12 from stock and prices the sale in the sales unit — no manual maths.
- Sell in the sales unit your customer expects
- Stock deducted in base units automatically
- Margin calculated on the right cost
| Invoice | Entered | Stock effect |
|---|---|---|
| INV-1051 | 3 packs | −12 each |
Conversions that keep your books honest
Buy one case and stock rises by twelve. Sell a pack and it falls by four. WisoBooks converts every line to the base stock unit behind the scenes, so quantity on hand and moving-average cost are always right.
- Automatic quantity conversion on every document
- Cost per base unit maintained accurately
- No manual maths, no rounding surprises
