Solution / e-invoicing

Get refused invoices moving again,
from refusal to the new invoice.

Each refusal opens a dossier with your customer. Your assistant gathers the documents and finds the gap. The agreement is signed by both companies. You can invoice again.

01 / The weak link

Dispute handling is the weak link
of electronic invoicing.

The e-invoicing circuit carries invoices and their statuses. The status “refused” means your customer does not accept the invoice: it records the disagreement but does not settle it. While the disagreement lasts, the invoice stays unpaid and lengthens your days sales outstanding (DSO), the average number of days your customers take to pay.

The data is structured.
The work no longer is.

What the reform provides when the invoice is refused

The French tax authority (DGFiP, Direction générale des Finances publiques) writes it: the « refused » status « does not settle the dispute between the parties ». The supplier must « instruct the disagreement with the buyer, keep the elements supporting its position and document the follow-up » — three obligations, with no dedicated tool. And the refusal is only the visible case: many disagreements carry no status at all — the invoice simply goes unanswered.

02 / How it works

From refusal to the new invoice,
in six steps.

01

The refusal is detected

From your account, you connect your accredited platform: the operator registered with the tax authority, through which your e-invoices travel. RIGA follows their lifecycle there: due dates, refusals, payments. Each refusal arrives with its code and its reason.

02

The dossier opens

A standing authorisation, signed once, lets a dispute dossier open automatically whenever one of your invoices is refused. The customer is invited at the address shown on the invoice. By accepting the invitation, the customer joins the dossier and authorises the people and assistants it designates to act within the scope set for its party.

03

Each side files its documents and asks its questions

Quote, order, delivery note, invoice: each party files its documents in the dossier or makes them accessible there, without opening its system. Each question is addressed to the other party. A coordination agent can organise requests and exchanges: it lists the documents filed and those missing, rephrases a question, proposes a procedural step. It does not rule on the disagreement and represents neither party.

Coordination agent → customer“The document ‘delivery note of 12/03’ is expected.”

04

Both parties record their agreement, if they reach a resolution

One of the parties proposes a resolution in writing: a credit note (the document that cancels all or part of an invoice), a corrective invoice (an invoice that replaces the first one), an acceptance or a partial agreement. Each party reads it and records it on behalf of its organisation, by simple signature, by signature on its device, or with a qualified certificate (a signing certificate issued by a qualified provider, which the signer already holds). The digital fingerprint (SHA-256) of the resolution is a string of characters that changes as soon as the text changes, so everyone knows they are signing the same text. Without agreement, the dossier documents the disagreement and each party's position.

05

The dossier closes, and each party keeps the archive

At closing, each party receives the dossier: the resolution or the record of disagreement, the signatures, the complete record and a report that lets it verify everything without us. RIGA changes neither the invoice nor the parties' accounting. At the end of the dossier, each party applies in its own system the resolution or the next step it recorded. At closing, the archive is sealed and the room key is disabled, then destroyed after thirty days. The encrypted archive remains available for ninety days and is never deleted before each party has retrieved it.

06

The new invoice is issued

You issue the credit note or the corrective invoice in your own system. RIGA picks it up on the connected platform and attaches it to the dossier.

03 / Each team's role

What each team does in the dossier.

Sales administrationThe team that tracks orders and customer invoices.
It owns the dossier: documents filed, questions addressed, answers kept.
Sales team
It brings the agreed terms and reviews the solution with the customer.
Accounting
It holds the signed agreement needed to issue the credit note or the corrective invoice.
CollectionsThe team that follows up customers who are late paying.
It sees where the disagreement stands before following up.
IT department
It connects the accredited platform once; refusals then arrive with nothing to re-enter.

In a small business, one person often holds several of these roles.

04 / Automation

Automated handling, human decisions.

An assistant is artificial-intelligence software that you authorise to work in the dossier, within the limits you set. It can neither sign nor consent.

05 / What the dispute dossier holds

Everything needed to work through the disagreement, and nothing more.

Refusal detection

On the accredited platform connected to your account, with the code and reason of each refusal.

A standing authorisation

Signed once, it lets the dossier open automatically. Every dossier opened keeps a trace of it in its record.

The real participants

The supplier, the customer, their teams and advisers. A coordination agent, and an observer if you want one.

Documents filed in the dossier

Never sent. You can withdraw access at any time, and it shows in the record.

Addressed questions

Each question is put to one party; the answer stays in the dossier.

A coordination agent that does not rule

It lists the documents, rephrases the questions and proposes procedural steps. It decides nothing and represents neither party.

A resolution recorded by authorised people

By simple signature, by device signature or with a qualified certificate, each signatory's choice — if the parties reach agreement.

An archive handed to each party

The resolution or the record of disagreement, the signatures, the record and the verification report. Kept encrypted, never deleted before each party has retrieved it.

For small businesses

A case your owner and team can work on together.

Bring the documents together, assign questions and review the proposed resolution with your customer. The owner retains control over the business’s commitments.

06 / Three ways in

You use the dossier as is, with your AI assistant, or from your own tools.

See the developers page

In the browser, nothing to install, for you and for your customer.

Your AI assistant prepares the matching of documents and a draft reply, within the limits you set. It does not sign and does not bind your organisation.

Your software detects refusals and opens the dossier through an application programming interface (API): the way two pieces of software exchange without human intervention.

07 / Verification

An audit trail each party verifies without us.

The audit trail is the record of every action, in order, with its author and its date. Each party exports it and verifies it on its own computer, with the public tool of VAL, the open format in which the record is kept, with no account with us. Verification covers the record — nothing was altered, every action was authorised, everyone stayed within their scope — not the merits of the disagreement.

A complete dossier was handled on our development environment: refusal detected on a connected platform, dossier opened, both parties invited, adversarial questions and answers organised by the coordination agent, resolution recorded by both parties — one by simple signature, the other by device signature — then closing, with an archive received by each and verified to the byte.

08 / Frequently asked

What we are asked before a dossier opens.

Who organises the exchanges?

A coordination agent, software, that belongs to neither party. It lists the documents filed and those missing, rephrases the questions and proposes procedural steps. It does not rule on the disagreement, does not characterise the facts and represents neither party. Each of its actions is recorded in the record.

Is there a human mediator?

No. RIGA does not provide a mediator. Each party can bring its adviser, or a mediator of its choice, into the dossier, with the rights it gives them for its party.

Does my customer have to install anything?

No. They are invited at the address shown on the invoice and enter the dossier from their browser. By accepting the invitation, they join the dossier and authorise the people and assistants they designate to act within the scope set for their party.

What happens to the invoice?

RIGA changes neither the invoice nor the parties' accounting. The dossier is where the disagreement is worked through. At the end, each party applies in its own system the resolution or the next step it recorded: credit note, corrective invoice, acceptance, partial agreement, or a record of disagreement.

Which platforms can be connected?

Accredited platforms connect from your account in a few minutes and are verified before activation. The first connections are under way.

What if my customer does not answer?

The dossier stays open, with the documents filed and the questions asked. The record shows what was asked, of whom and when. Without agreement, the dossier documents the disagreement and each party's position; nothing is recorded on a party's behalf without its signature.

Where are the documents hosted?

Documents are hosted with a French provider in France. The record and metadata are hosted in the European Union. Each room is encrypted with its own key. At closing, the archive is sealed and the room key is disabled, then destroyed after thirty days. The encrypted archive remains available for ninety days and is never deleted before each party has retrieved it.

Does a refused invoice lengthen days sales outstanding (DSO)?

Yes. Until the disagreement is settled, the invoice is not paid. The dossier opens as soon as the invoice is refused, so that the work starts before the due date.

Do I have to issue a credit note after an invoice is refused?

Whether to issue a credit note, a corrective invoice or a new invoice is decided with your accountant. The dossier keeps the agreement that justifies it.
