Learn a check, then try it
Six short invoice tutorials
Start with the task in front of you. Each narrated tutorial uses fictional documents, explains a concrete review step and links to a tool and worked example. These are educational calculations, not live extraction recordings.
Check whether an invoice's line items add up
A matching total can hide a line error. Work through a fictional invoice where four hours at USD 75.00 are printed as USD 375.00. Download the example PDF and calculated answer, then compare what the checker reads. Educational calculation; this video does not demonstrate a live OCR run. The standalone checker does not verify agreed rates or delivery.

Convert a supplier invoice PDF to Excel with line items
The review steps for converting a supplier invoice into an Excel result: source, line items, arithmetic and export. Use the linked fictional worked example to compare expected values with the tool's reading. This is an instructional explainer, not a live processing recording. Excel keeps line items; the invoice CSV export has header totals.

Why an invoice total can look correct while a line is wrong
Reading a number correctly and checking its meaning are separate jobs. This fictional invoice's printed amounts total USD 500.00, but four hours at USD 75.00 should produce USD 300.00 instead of USD 375.00. Calculated example, not an accuracy or comparative benchmark.

Review an invoice before sending it to Xero
Review the document type, signed amount, lines, approval and tax treatment before an accounting push. This educational workflow does not demonstrate a live Xero connection or posting. IPP's Xero push creates drafts and does not set tax codes; accounting pushes require a paid plan or trial.

Check a VAT-inclusive invoice without counting tax twice
Work through a fictional tax-inclusive invoice: ZAR 1,150.00 gross contains ZAR 150.00 VAT at its printed 15% rate. Adding that VAT again would produce ZAR 1,300.00. Arithmetic illustration only; it does not determine legal tax treatment or configure accounting tax codes.

What an invoice math checker cannot catch
Correct arithmetic can coexist with a wrong agreed rate. A fictional invoice charges four hours at USD 75.00, while a separate agreement says USD 60.00. Learn which checks belong to the invoice itself and which require outside evidence. IPP's standalone checker does not verify agreed rates, delivery, prior payment or fraud.
