An amount agrees
USD 1,500 and USD 900 total USD 2,400. Against an independently reviewed USD 2,400 register, the difference is zero. Identity and duplicate checks still remain.

Free Invoice Batch Control Total Checker
Before releasing a small invoice batch, reconcile its amount with the reviewed billing register. A matching total is one control: also verify document identity, client, currency and delivery state.
What you can do here
Compare three reviewed invoice totals with an independently prepared expected batch total and show the signed difference.
Built for real invoice workflows
Use the control total with identity checks and PDF previews before scheduling the reviewed invoices.

Calculation notes
How the result is calculated
Batch amount = invoice 1 + invoice 2 + invoice 3. Difference = batch amount − independently reviewed expected amount. A positive result is an excess; a negative result is a shortfall. Keep one currency and one tax basis. Equal amounts cannot prove that the correct documents, clients or work items are present.
Formulas and examples reviewed October 2, 2026. Illustrative figures; no tax or contractual determination.
A missing ready item
USD 1,500 and USD 900 total USD 2,400 against USD 2,700 expected, producing a USD −300 shortfall. Investigate the register and documents; do not create a USD 300 charge merely to force agreement.
Questions about this calculation
Can a matching total hide an error?
Yes. A missing USD 500 invoice and a duplicate USD 500 invoice cancel arithmetically. Check the work references and document IDs separately.
Can I add USD and EUR invoice totals?
No. Run a separate check for each currency and keep the expected total on the same tax basis. This checker performs no conversion.
How to use it
1
Enter up to three final invoice totals on the same currency and tax basis.
2
Enter the independently reviewed expected batch total.
3
Investigate the signed difference before releasing the batch.
Why it helps
Check a batch against an independent amount.
