Why one item needs several units

Many items are bought, stored, and sold in different units: you buy a carton of 24, store eaches, and sell singles. AWRA lets one item carry several units so the same product can be transacted the way each step of the business actually handles it.

The alternative — creating a separate item for "carton" and "each" — splits stock and hides the truth. One item with units keeps a single on-hand figure that everyone reads correctly.

A drinks distributor buys soda by the crate of 24, the warehouse counts crates, and the shop sells cans. Modelled as one item with a base unit of "can" and a purchase unit of "crate (24)", a delivery of 10 crates adds 240 cans to on-hand automatically — no mental arithmetic, and the shelf count and the purchase order still speak the same language.

Key takeaways

One item can carry several units (purchase, stock, sell).
Units let each step transact the way it really handles the goods.
Splitting into separate items per unit hides the true on-hand.
Example: buy crates, sell cans — one item, one honest on-hand figure.

Base unit and conversion factors

The base unit is the smallest unit you track — usually the one you sell or count in. Every other unit is defined by a conversion factor against it: 1 carton = 24 each, 1 box = 12 each. Get the base unit right first, because everything converts to it.

Conversion factors are where accuracy lives. A wrong factor — a carton set to 20 when it is really 24 — quietly corrupts every receipt and sale until someone notices the counts drifting.

Choose the base unit you will most often count and sell; for retail that is usually the "each". Then define purchase units on top: 1 case = 24 each. When you receive 5 cases, AWRA records 120 each; when you sell 1 each, it deducts 1. Double-check each conversion factor at setup — a two-minute check that prevents months of drift.

Key takeaways

The base unit is the smallest unit you track and sell in.
Other units are defined by a conversion factor to the base.
A wrong factor silently corrupts every receipt and sale.
Verify each conversion factor at setup to prevent count drift.

Buying in one unit, selling in another

The everyday payoff: you receive a purchase order in cartons and sell at the till in eaches, and AWRA converts between them on the fly. The PO, the goods receipt, the shelf count, and the sale all stay reconciled because they share one base unit underneath.

This removes the spreadsheet someone keeps to "translate" supplier cartons into shop singles. The translation lives in the item, applied automatically every time.

Receiving a PO for 10 cartons of an item whose carton = 12 adds 120 eaches to stock; the supplier invoice still reads "10 cartons" for matching, while the shop sells and counts in eaches. If you ever see stock jump by an odd amount after a receipt, the conversion factor is the first thing to check.

Key takeaways

AWRA converts between purchase and sell units automatically.
PO, receipt, count, and sale stay reconciled via the base unit.
No more manual "carton-to-each" translation spreadsheet.
An odd stock jump after receiving usually means a wrong factor.

Common unit mistakes

The classic errors are predictable: selling in the purchase unit by accident (a whole carton at single price), setting the base unit too large so you cannot sell singles, or changing a conversion factor after stock exists and skewing history.

Each is avoidable with discipline: pick the base unit as the smallest sellable unit, lock conversion factors before transacting, and treat a factor change like an adjustment that needs care.

If you must change a conversion factor on an item that already has stock and history, recount and adjust rather than silently editing — the old transactions were recorded under the old factor. The safest habit is to get units right at item setup, before the first receipt or sale, so history is never built on a moving definition.

Key takeaways

Common errors: wrong sell unit, too-large base unit, late factor changes.
Pick the base unit as the smallest sellable unit.
Lock conversion factors before transacting on the item.
Changing a factor after stock exists needs a recount, not a silent edit.
