Pelarasan bil dibuat selepas tempoh bil berubah.

Pelarasan bil means bill adjustment or billing adjustment.

• pelarasan = adjustment
• bil = bill

Pelarasan comes from the root laras, and the pe-...-an pattern often forms a noun referring to a process, result, or act. So pelarasan is the noun adjustment.

The sentence is:

Pelarasan bil dibuat selepas tempoh bil berubah.

Here, bil appears in two different noun phrases:

• pelarasan bil = bill adjustment
• tempoh bil = bill period / billing period

So the repetition is not strange in Malay. It is simply connecting two different ideas to the noun bil.

In English, we might avoid repeating bill so often, but Malay often allows this kind of repetition naturally.

Dibuat is a passive form.

• dibuat = is done / was done / made
• membuat = to do / to make, or does/makes in an active clause

So:

• Pelarasan bil dibuat... = The bill adjustment is done / was done...
• Syarikat membuat pelarasan bil... = The company makes/did the bill adjustment...

Malay uses the passive very often, especially when the action matters more than the person doing it.

The sentence does not say.

Because it uses the passive dibuat, the focus is on the adjustment itself, not on the agent. English does this too:

• The bill adjustment was made after...

If you wanted to mention who did it, you could add that information in an active sentence, for example:

• Syarikat membuat pelarasan bil selepas tempoh bil berubah. = The company made the bill adjustment after the billing period changed.

Tempoh bil means billing period, bill period, or sometimes billing cycle, depending on context.

• tempoh = period, duration, term
• bil = bill

So tempoh bil berubah means the billing period changed.

In practical usage, this could refer to the time span covered by a bill, or the billing cycle dates.

Berubah means to change or to become different.

It is usually intransitive, meaning the subject changes by itself:

• tempoh bil berubah = the billing period changed

This is different from a verb meaning to change something. For that, Malay often uses something like mengubah:

• Syarikat mengubah tempoh bil = The company changed the billing period

So:

• berubah = change, become changed
• mengubah = change something

Yes, it works like a clause introduced by selepas, meaning after.

Breakdown:

• selepas = after
• tempoh bil = billing period
• berubah = changed

So selepas tempoh bil berubah means after the billing period changed.

Malay often allows this very directly, without adding extra words like it had or has.

A fairly literal breakdown is:

• Pelarasan bil = bill adjustment
• dibuat = was done / is done
• selepas = after
• tempoh bil = billing period
• berubah = changed

So the structure is basically:

Bill adjustment was done after billing period changed.

More natural English would be:

The bill adjustment was made after the billing period changed.

Malay usually does not use articles like a or the, and it often does not mark tense the way English does.

So one Malay sentence can correspond to several English possibilities depending on context:

• The bill adjustment was made after the billing period changed
• A bill adjustment is made after the billing period changes
• The billing adjustment was done after the billing period changed

Context tells you which English version fits best.

Not by itself.

Dibuat is a passive form, but it does not automatically mean past tense. Malay verbs usually do not change form for tense the way English verbs do.

Time is often understood from:

• context
• time words
• surrounding information

In this sentence, English often translates it as past tense because the sequence after the billing period changed sounds like a completed event. But in another context, it could be more general:

• Bill adjustments are made after the billing period changes.

Yes. A more active version would be:

Syarikat membuat pelarasan bil selepas tempoh bil berubah.

That means:

The company made the bill adjustment after the billing period changed.

The original sentence is more impersonal and formal, which is common in administrative, billing, and customer-service language.

Yes, it sounds fairly formal and administrative.

Words like:

• pelarasan
• tempoh
• dibuat

are very common in official notices, billing explanations, and service messages.

In everyday speech, people might use simpler phrasing depending on the situation, but this sentence is perfectly natural for formal written Malay.

In Malay, bil can sometimes be an abbreviation for bilangan in certain formal contexts, meaning number. But here, that is very unlikely.

Because of the surrounding words:

• pelarasan bil
• tempoh bil

the meaning is clearly bill or billing, not number.

So in this sentence, bil = bill.
