Can I use a handwritten diesel bill from a local supplier for carbon reporting?
Yes, if it shows the date, supplier, litres and your business name, and you can back it with a payment record. A verifier will look for a matching bank or cash entry and your stock or logbook. Where a bill lacks litres, record how you converted it.
What makes it usable
- Date of supply and the supplier's name or stamp.
- Quantity in litres, not only a rupee amount.
- A payment entry in your books that matches it.
Make it stronger
Keep a simple register: date, litres received, where the fuel went. A handwritten bill plus a register reads far better than either alone.
What Senseible does here
Senseible keeps each figure tied to its invoice, factor and method version, so a verifier can trace any number back to the document it came from.
