Proration in the rental industry is the practice of calculating rental charges based on the exact amount of time the equipment or item was used, instead of charging for a full billing period.

For example, instead of requiring customers to pay for a full week when they return the equipment after 8 days, the rental system can charge the weekly rate plus a proportional share of the next period. This ensures the customer pays only for the time they used beyond the standard period.

Example:
If a weekly rate is $675 and a customer rents for 8 days, prorated pricing can charge:
​1 full week + 1/7 of the weekly rate, instead of 1 week + a full extra day.

This results in more accurate and fair pricing when rentals run longer than expected.

Prorated behavior depends entirely on how your pricing tiers are set up. To configure pricing for a product:

Example:

When adding a price tier, use the Unit dropdown to select:

How you choose these Units determines whether proration applies.

To enable proration:

Turning this on allows proration, but the actual behavior depends on how your tiers are structured.

Quipli always follows this pricing logic:

Which of these happens depends entirely on how your pricing tiers are designed.

In this setup, the user creates “weekly” and “monthly” pricing by selecting Unit = Per Day and entering the number of days (e.g., 7 or 28). Because these tiers are defined as fixed day blocks, Quipli does not treat them as true weekly or monthly periods.

Example tier setup using Day units:

With prorated pricing On, these still act as fixed blocks. Since smaller tiers exist (like Per Day), leftover time is filled using the smaller tier — not prorated within the larger tier.

Examples:

This method is ideal if you want predictable block-based pricing and prefer extra time to be billed at the daily rate.

If you instead select:

then Quipli switches to treating these as true weekly/monthly periods — which triggers Pattern B (True Proration).

This setup uses actual weekly or monthly units so Quipli can prorate inside these periods.

Example tier setup using true time units:

Here, you are not manually entering 7 or 28 days — you are selecting true weeks/months. This enables proration.

Examples:

This creates clean, expected prorated pricing around weekly or monthly boundaries.

Proration is based on the actual rental duration. Your Pick Up & Drop Off settings can affect how that duration is calculated and may influence whether proration applies or whether an extra tier is triggered.

To avoid unexpected tier application:

If these settings push the rental into the next day, beyond store hours, or outside a grace window, extra time may be added to the rental duration — which can change whether proration is used or whether a full additional day/week is charged.
