Sample invoices
Five realistic, made-up invoices you can use to try the app. Download one, then drag it onto the matching category on your dashboard to see how it's read.
All suppliers, account numbers and figures are invented. Under each sample, we explain what should be pulled from it, and what makes it a good test.
Annual electricity statement
Voltara Energy Ltd (fictitious)
A full year of electricity bills in one document, with separate day and night readings for each month.
- One record for every month of 2025
- Day and night usage added together into one monthly total (e.g. January: 934 + 412 = 1,346 kWh)
- March, July and December marked as estimated, because the bill itself flags them that way
- Standing charges and other fees ignored, since they're costs, not energy use
Why it's tricky: It's easy to mistake the day and night readings for two separate things, or to accidentally count the same usage twice when it also shows up in the charges table.
Winter gas bill spanning three months
Hearthstone Gas (fictitious)
One bill covering 12 Nov 2025 to 9 Jan 2026, 59 days that cross three months and a new year. Measured in m³, billed in kWh.
- The billed usage of 4,342 kWh, in the units our emission factor needs
- Split across the three months based on how many days fall in each
- All three months marked as estimated, since splitting a bill like this is always an approximation
- The m³-to-kWh conversion on the bill is recognised, so the usage isn't counted twice
Why it's tricky: Bills that cross over months, or even years like this one, are one of the trickiest things to get right, and this sample tests exactly that.
Quarterly waste invoice with a lift log
BinWise Environmental (fictitious)
A three-month invoice listing eleven separate bin collections across three types of waste: general, recycling and organic.
- Collections grouped by month and by waste type
- Weights converted from kilograms to tonnes
- For example, January general waste: 128 + 142 = 270 kg, or 0.27 tonnes
- Bin rental and other fees ignored, since they're costs, not waste
Why it's tricky: One invoice covers three different waste types, each with its own emission factor. The bill uses technical names for them, which have to be matched to our simpler category names.
Two-month water bill
Regional water utility (fictitious)
A two-month water bill for March and April, with a meter reading and separate charges for supply and wastewater.
- 182 m³ of usage split between March and April based on the number of days in each
- Both months marked as estimated, since the usage is split rather than metered separately
- Supply and wastewater charges recognised as the same water, so it isn't counted twice
Why it's tricky: The meter reading is written in an odd format, the way real bills sometimes are, so it's the total usage figure that should be trusted, not the raw reading.
Coach hire invoice for away fixtures
Shamrock Coach Hire (fictitious)
Five away-match trips across March and April, each showing the distance travelled and how many passengers were on board.
- Distance × passengers for each trip, added up by month
- For example, 8 March: 148 km × 41 passengers = 6,068 passenger-km
- Hire charges and other costs ignored, since they're not related to distance
Why it's tricky: Coach travel is measured by distance per passenger, so two numbers need to be multiplied together rather than just reading off one figure. An invoice that only shows a price, with no distance, can't be used.

Subject: Requesting our usage data for [YEAR] Hi [Supplier / Contact Name], We're [Club Name], and we're putting together our annual carbon and cost report. To do that accurately, we need our usage history with you for [YEAR], ideally broken down month by month. Could you send us: - [Electricity / gas / water / waste] usage for each month of [YEAR] (kWh, m³, tonnes, whichever you measure it in) - Copies of the invoices or statements covering that period, if a summary isn't easy to pull together If any of this is already available through an online account or customer portal, a link or export works just as well. Thanks for your help, [Your name] [Club Name]
