Impact of time zones on MRR calculation

Why time zones can influence the MRR calculation

In Fincome, invoice line items are interpreted based on their start and end date and time. To ensure calculation consistency, the platform automatically applies the configured time zone on the account (by default: UTC +1 for France).

This means that when an invoice line for example starts on 01/31/2025 at 11pm UTC, it is converted to 02/01/2025 at 00:00 (UTC +1) in the MRR calculation. ➡️ As a result, this line will be accounted for starting from February and not from January.

Concrete example

• Actual start date on the invoice : 01/31/2025 at 11pm UTC

• Applied time zone (UTC +1) : offset of +1 hour

• Start date interpreted in Fincome : 02/01/2025 at 00:00

• Result : the MRR only appears starting in February.

How to avoid a “gap” in MRR

If you notice a one-day shift due to the time zone: ➡️ Simply enter the end of the previous period as the 1st of the following month to ensure continuity without a “gap” in MRR.

Example:

• If your previous period ends on 31/01/2025, instead indicate 01/02/2025 as the end of the period. This way, the MRR will be smooth from month to month.

Best practices

• Check that your invoice dates are consistent with your local time zone.

• If you import data from an external tool (Stripe, Pennylane, etc.), make sure the exported dates are aligned to the same time zone.

• If in doubt, always prefer full hours (e.g. 00:00) to avoid one-day shifts.
