How Zeronda works

A clear route from invoice to payment.

The invoice sets the amount, the sponsor makes the decision and a secure checkout completes the payment. Here is what happens at each step.

Step 01 · Invoice Intelligence

Read the invoice before making the request.

The beneficiary uploads the original file and names the sponsor. Invoice Intelligence derives the invoice details and payable total instead of asking the beneficiary to type an unsupported amount.

  1. 1
    Store and register

    Zeronda checks the file type, hashes the private file and adds it to the invoice registry.

  2. 2
    Calculate risk

    The system reads the supplier, invoice number, dates, currency and totals, then gives the evidence a transparent 0–100% risk score with named drivers.

  3. 3
    Share the assessment

    Payable, safe evidence reaches the sponsor even when its risk is high. Unsafe files, duplicates or an unknown payable amount stop the payment workflow.

Step 02

The sponsor chooses the amount.

The sponsor reviews the original invoice and chooses any positive amount up to the remaining balance. Zeronda will not create a payment above that limit.

Step 03

Common questions

Straight answers before you begin.

Does a low risk score prove the invoice is genuine?+

No. The score summarises concerns found in the evidence available to Zeronda. It is not a probability of fraud, authenticity finding or guarantee. The sponsor still decides whether to pay and should verify the request in proportion to its risk.

Can a high-risk invoice reach a sponsor?+

Yes. If the evidence is safe to open and has a usable payable amount, Zeronda shares the score and escalating warning instead of silently making the decision. Malware, corrupt files and duplicates remain blocked.

Can the same invoice be submitted twice?+

Invoice Intelligence blocks exact and lookalike duplicates for the same beneficiary and records every attempt. A corrected invoice needs to replace the earlier version explicitly.

What if I was invited before signing up?+

Sign up with the same work email that received the request. It will then appear in your sponsor inbox.

Does Zeronda store payment credentials?+

No. A secure checkout receives the sponsor’s payment details. Zeronda stores safe payment references and outcomes, not raw credentials.
