What to do
Keep the invoice number, issue date, and service period for each recurring bill. Similar descriptions and equal amounts across months can be legitimate. Use the period and source reference to distinguish records without treating the account number as a new invoice identifier.
A recurring arrangement does not guarantee identical prices or dates on every invoice.
Two worked review cases
These cases are fictional teaching data, not measured extraction results. Use the source excerpts to practise deciding what belongs in the reviewed output.
| Case | Fictional source excerpt | Review decision |
|---|---|---|
| Same amount, new period | INV-SEP covers September 50.00; INV-OCT covers October 50.00 | Retain two distinct records with their periods. |
| Resend | Two files both show INV-OCT and the same period | Review as a potential resend before adding a second record. |
Suggested review columns
| Column | Definition or instruction |
|---|---|
| Invoice number | Identifier for this specific billing document. |
| Service period | Printed period covered by the recurring charge. |
| Account or subscription reference | Persistent account reference, kept separate from invoice number. |
These are suggested staging-sheet columns. Printed facts can inform field descriptions in Parzable’s Schemas view; source references, review statuses, and decisions must be supplied by your own review process.
A practical review sequence
- Capture billing-period boundaries where the source provides them.
- Compare invoice identifiers rather than assuming every equal amount is duplicated.
- Record unusual adjustments separately from the recurring base charge.
Errors to avoid
- Do not generate a missing month’s invoice from the previous month’s data.
- Account numbers usually persist across bills and are weak invoice-identity keys.
Use the case worksheet with a small sample
Download this page’s worked-case worksheet. It contains the two fictional cases above and a blank row for your own review exercise. Keep any real source documents in your agreed storage process.
For the broader product workflow, see the related guide. Parzable accepts PDF/image inputs and downloads CSV. Suggested structures here are review targets; nested item rows, automatic approvals, and destination integrations are not guaranteed.
