Purchases

A purchase is a vendor bill: seeds, trays, fertilizer, growing media — or ready plants bought in from another nursery. The moment you save it, everything on the bill lands where it belongs:

Plants become a purchased batch (on Plant Summary and Sowing Batches) and are added to that plant's item on the Stock screen.
Everything else is added to its item on the Stock screen.

The bill is always worked out again when you save — item discounts, any bill discount (taken off before GST), GST and freight — so the totals you see are the totals that are stored.

Edit a purchase

Fix a mistake on a saved bill

Choose Edit purchase from the row menu on the Purchases list, or the button on the purchase's own page. The same form you used to record it opens with everything filled in. You can change the vendor, invoice number, date, unit, payment, freight, notes and bill discount — and the items themselves: add or remove a line, change the product, plant or variety, quantity, rate, discount or GST.

Price, GST, discount and payment changes only change the bill. Your stock is not touched.
Changing an item, its quantity or the unit also corrects the stock and the plant batch it created, so both stay right.
Removing a line takes its stock back off and removes its plant batch.

One rule: if plants or stock from an item were already sold or used, that item's quantity can't be changed any more (its price still can). The message says what was sold — for example "12 plants from SB-104 were already sold. Cancel/delete those sales first."

On a credit purchase, the amount already paid can't be more than the new total — lower the paid amount first.

Cancel a purchase

The bill was wrong or the goods went back

Cancel purchase takes back everything the purchase added: its stock comes off the Stock screen and its plant batches are removed. The purchase stays in your list as Cancelled, so you still have the record. A cancelled purchase can't be edited.

Delete a purchase

Remove it from the list

Delete purchase works for any purchase. If it isn't cancelled yet, its stock and plant batches are taken back first — exactly like cancelling — and then it is removed from your purchase list. A purchase that is already cancelled is simply removed from the list.

When cancel, delete or edit is refused

Something from it was already used

A purchase can only be taken back while nothing it brought in has been used. If it can't, the message tells you what and what to do:

Plants sold from its batch — cancel or delete those sales first.
Stock used below what the bill added (e.g. "only 4 kg of Urea is left in stock, but this purchase added 10 kg") — undo that usage, or correct the stock with Adjust Stock, first.

A plant batch that came from a purchase can't be deleted from the Sowing Batches screen — edit or delete the purchase instead, so the batch and your stock stay in step.

Tips

Keeping purchases clean

Typo in a price or the GST rate? Edit — it never blocks, even after you've sold the plants.
Wrong quantity? Fix it before you sell from the batch; afterwards the quantity is locked.
Prefer Cancel over Delete when you want the bill to stay visible for your accountant.
