Part-month (pro-rata) charges appear when a service is active for only part of a billing period.

At Scott Mobile:

Billing cycle: 28th to 28th each month

Invoices are generated mid-month (so you may see charges that cover time already used and/or time coming up, depending on the service and timing)

You may see part-month charges for three main reasons:

You’re a new customer receiving your first bill

You change your plan (upgrade/downgrade)

You cancel/disconnect a service

1) New customer (first invoice)

If you join part-way through the cycle, your first invoice may include:

A part-month charge from your start date up to the next 28th, and

Your next full billing cycle (28th–28th), depending on how your service is billed.

Example

You joined on 10 January

Current billing cycle ends on 28 January

Next full cycle is 28 January – 28 February
✅ Your first bill may include a part-month charge (10 Jan – 28 Jan) plus the next full cycle (28 Jan – 28 Feb).

2) If you changed plans

If you upgrade or downgrade during a cycle, your invoice may show:

A part-month charge for your new plan from the change date to the next 28th, and/or

A part-month credit for your old plan (if you had already paid for time you didn’t fully use).

Example

You changed from Plan A to Plan B on 10 January

You may see a credit for unused time on Plan A (10 Jan – 28 Jan), and

A charge for Plan B (10 Jan – 28 Jan)

Your next full month for Plan B is 28 Jan – 28 Feb.

✅ This ensures you only pay for the plan used on each date.

3) If you requested cancellation / disconnection

If you request disconnection or cancel mid-cycle, a part-month charge may apply to cover service used up to the end date (and any notice period that applies under your service terms).

Common scenarios:

Cancel mid-cycle: your final invoice may include a pro-rated amount up to the service end date (often up to the next 28th, depending on timing and terms).

Port out to another provider: your final invoice may include charges up to when the port completes, plus any applicable notice/contract terms.

Example

Disconnection request received 8 June

Your billing cycle runs 28th–28th

If your service ends part-way through a cycle, the final invoice may include the remaining pro-rated portion up to the end date (and/or cycle end), based on the applicable terms.

Why invoices are generated mid-month

Because invoices are generated mid-month, you may receive an invoice before the cycle ends. That invoice can include:

Standard monthly charges for the upcoming cycle, and/or

Pro-rated adjustments (part-month charges/credits) for changes made since the last invoice.
