Recycling plant system
Buys and sells recyclable material across four scales on one PC — three floor scales at the counter and a truck scale in the yard — so one purchase can be several materials, each weighed where it fits.

Counter PURCHASE
One card per floor scale. A supplier's materials go on whichever platform fits, at the same time.
There is no box to type a weight into: without a scale, nothing is weighed.

✎ Aluminium: catalogue $23.50, paid at $24.00 — authorised by Admin 02. A price above the catalogue does not save without a name against it, and the PET line comes in by the sack, so its tare is the sacks.

Truck scale PURCHASE
Two weighings frame the purchase; each material is worked out as it comes off the truck.

On Complete, the reading the truck is standing on becomes its tare. Nobody types it, and nobody has to add the lines up to check it: the arithmetic closes or the truck does not leave.

A purchase is only counted once its second weighing exists: the truck still on site and the load still on the road are listed, but they are not in the day's totals yet.

The software does the adding up; a person does the counting. A difference is not an error in either — it is the one number the close exists to put a name against.
Transfers are recorded against the shift but never enter the drawer, so they are counted beside the cash and not in it.

The counter
Four scales, one PC: three low-profile floor scales at the counter and a truck scale in the yard, each on its own serial port. A supplier brings several materials at once, so a purchase is a basket — each line weighed on whichever scale it fits, all of them on one ticket.
Buying at the counter
Every floor scale is a column on the screen, because a supplier brings several materials at once. This is the order the drawing added up — the same three weights, the PET’s tare taken by the sack, and one price raised above the catalogue that would not save without a name against it.
Weighing down
The weighbridge weighs a truck twice and gets one number. This truck is weighed twice and gets a basket: it drops one material, is weighed again, and each drop is that material’s weight. The empty truck’s reading is the tare, so gross minus tare has to equal the lines.
Every operation
Purchases and sales in one list, because to a recycler they are two ends of the same kilo. The counter order is the top row, still to be paid; the truck is on site; a load sold to a mill is on the road. Only operations with a second weighing count towards the day.
The till
A recycler pays across the counter, so purchases leave as cash. What the drawer should hold is arithmetic — float, plus cash in, minus cash out — and closing the shift is a person counting it. The software adds; the person counts; the difference gets a name.
The dashboard
The owner’s screen. Two banners before any chart — what the yard owes suppliers and what customers owe the yard — and both are sums of rows other screens already hold. The cash tile is the till’s own figure, not a copy of it.
Settling at a distance
A load sold to a mill is weighed here and again at the mill, and the two never agree. It is settled per material on a weight both sides accept, and the gap is written down: merma, origin minus destination. The red row is their scale reading heavier than ours.
