Understanding Week Periods in Reporting
Summary: The GG system uses three different week periods across its reports — ISO Week, Monday-to-Sunday, and Sunday-to-Saturday — depending on the type of data you're viewing. This guide explains what each one means, where you'll encounter it, and why the system uses different periods for different reports, so you can interpret your data accurately.
Reporting in the GG system uses a few different week periods, and which one applies depends on the type of information you're accessing. Understanding the differences will help you interpret reports correctly and avoid confusion when figures appear to fall into unexpected weeks.
ISO Week
ISO Week is part of the ISO 8601 date and time standard issued by the International Organisation for Standardisation. It runs Monday to Sunday and is the primary week format used throughout the system, including:
- Fulfilment
- Live Baskets
- Box Builder
- Product Availability
- Finances
When orders are generated, they're assigned to a specific ISO Week based on the delivery or collection date, not the date the order was processed. This means an order processed in one week for a delivery the following week will always appear in the correct ISO Week for that delivery.
Monday-to-Sunday reports
Some reports — most notably Finances → Invoices — also run Monday to Sunday, but they're tied to the date the card transaction was completed, not the delivery date. This can lead to a few edge cases worth knowing about:
- Orders processing at midnight on Sunday. During BST, these may land in the following week. During GMT, they may land in the previous week.
- Payments taken outside of automatic processing. If an order's initial payment fails (for example, a card decline) and you take payment manually later, the transaction will appear in the invoice for whichever week the successful payment was taken — not the delivery week.
In short, ISO Week reports follow the delivery date, while invoice reports follow the payment date.
Sunday-to-Saturday data trends
Some data trends — including those on your home dashboard and in the Data Hub (such as Sales Analytics) — run Sunday to Saturday instead.
This is because Sunday is a common order-processing day across our user base. Using a Sunday-to-Saturday week ensures that orders generated on a Sunday are captured in the same week as the rest of that sales cycle, giving you a more accurate view of weekly sales trends.
