- Page count and sides
- Copy jobs are priced per page and per side, so state the number of originals, the number of sets, and whether copies were single or double sided. This lets an office customer check the bill against what it collected.
- Colour or black and white
- Colour copies cost several times more than monochrome. A separate line for colour pages shows why the total is higher and avoids the impression that one rate was applied to the whole job.
- Paper size and type
- A4, legal, A3 and thicker sheets used for certificates or covers are priced differently. Mention the size and GSM so a repeat order can be quoted at the same rate.
- Finishing work
- Spiral binding, tape binding and lamination are often added at the counter. Listing them as their own lines, with quantity, makes the job easy to verify and keeps services separate from the stationery goods sold.
- Customer GSTIN for office and college accounts
- Lawyers, coaching centres and companies that run monthly accounts want input tax credit. Capturing their GSTIN on a full tax invoice, rather than a counter slip, lets them claim the 18% charged.
- Job or token number
- Busy shops hand over a token when a job is dropped off. Printing it on the bill links the paid invoice to the right bundle and helps when a customer comes back for reprints.
