An adjustment changes stock at one location, up or down, with a reason. It is how stock enters or leaves your records outside of transfers, counts and sales.

When to use one

If you have counted a location and found many differences, use a stock count rather than a series of adjustments. A count records what you counted and posts the variances in one operation, which is a far clearer record.

Creating one

1

Open Inventory, then Adjustments

Choose New adjustment.
2

Select the location

Where the stock actually is. An adjustment affects one location only.
3

Choose the reason

Be honest. “Loss” and “correction” mean different things, and knowing which is which is the point of recording the reason.
4

Add your lines

For each: the item, and the quantity.Positive quantities increase stock. Negative quantities decrease it.
5

Add notes

What actually happened. “Three cartons water-damaged, roof leak in store room, 14 March” is useful. “Damage” is not.
6

Save as draft

Nothing has moved yet.
7

Check it

Right items, right quantities, right signs, right location.
8

Post it

Stock movements are written and balances update.

Draft and posted

Once posted, an adjustment cannot be edited. If it is wrong, void it — which creates reversing movements — and post a correct one. Both remain visible, which is what makes the history reliable.

Voiding

1

Open the posted adjustment

From Inventory → Adjustments.
2

Choose Void

Only an administrator can void. A reason is required.
3

Reversing movements are created

Stock returns to what it was before. The original adjustment stays visible, marked void.

What Bumara checks

Negative stock

By default, an adjustment that would take a balance below zero is refused, naming the item that is short. This is usually the right answer. A negative balance means your records and reality have diverged, and posting anyway makes that worse. Where an override is genuinely needed — goods physically received but not yet entered — an administrator can override with a documented reason, which is recorded.

Opening balances

Your first adjustment at each location is the opening balance. See Setting up inventory. Use the reason “opening balance” so it is distinguishable from later corrections when you review your history.

What happens after posting

Reviewing adjustments

Adjustments deserve periodic review — they are the operation most open to abuse, since they can make stock disappear. Filter by reason and by date from the adjustments list.

Good practice

  • Post promptly. An adjustment made a week after the event is guesswork.
  • Write real notes. Someone will read them in six months.
  • Use the right reason. Damage, loss and correction are genuinely different.
  • Restrict who can post. Not everyone needs the ability to make stock disappear.
  • Review monthly. Patterns are visible in aggregate, not in individual entries.
