How to scan electricity invoices into your GHG inventory

1. Choose the facility the invoice belongs to.
2. Upload the file: a PDF, or a clear photo taken with your phone.
3. Review the extracted fields: supplier, meter, period and quantity (kWh, litres, m³). Fields the scanner is unsure of are highlighted.
4. Correct or confirm each highlighted value against the paper invoice.
5. Save. The record is calculated immediately and the original document stays attached as evidence.

• Prefer the original PDF from the supplier's portal over a photo.
• For photos: flat surface, good light, the whole page in frame, no shadows.
• Check that the period is the consumption month, not the issue date.
• If the invoice shows several meters, confirm the quantity matches the meter for this facility.
• One invoice per upload. If a scan fails, use manual entry and attach the file as evidence.

Suppliers keep the same layout month to month, so after you confirm the first invoice from a supplier, later invoices from them are usually read with fewer questions.

• Day and night tariffs: the total kWh is what counts.
• A bill covering two months: split the kWh by days into the two periods.
• Shared building, one meter: enter your share, by sub-meter or floor area, and note the method on the record.
• Own solar panels: enter only electricity bought from the grid. Self-generated renewable power has no Scope 2 emissions.
• Generator electricity: not Scope 2. Enter the generator's fuel under Scope 1.

The same invoice uploaded twice shows up as electricity that looks doubled. Delete the duplicate.
