How is Billabex different from an automated reminder?

A reminder sends a message on a scheduled date. Billabex also handles what follows: processing the reply, tracking a dated promise, sending an available document or flagging a blocker to your team. Amounts are rechecked before sending against available data. Emails are automatic; SMS and letters are explicitly triggered and paid for with credits.

What happens when a customer replies?

The agent identifies what is holding payment back: a missing document, internal approval, requested extension, promise or dispute. It then adapts the follow-up or hands the decision to you with the useful context.

Do I stay in control?

Yes. You can review every exchange, pause a follow-up or take over at any time. When a decision belongs to you, the agent hands over the case with its full context.

How does Billabex protect my customer relationships?

The agent emails from the domain of Revoptim, our amicable collections company, and states that it acts on your behalf. This identified third party gives invoice follow-up a dedicated contact. You set the tone and boundaries to protect your commercial relationships. Disputes, discounts and negotiated payment plans go back to your team.

Does Billabex work with my invoicing software?

Native connectors include Odoo, Pennylane, Qonto, Sellsy, Stripe and Zoho Books. For NetSuite, Sage, Chargebee or a custom system, we assess the connection and available data with you before committing. Manual entry, imports and the API can also supply Billabex with data.

Is my data protected?

Yes. Data is hosted in the European Union, and Billabex is GDPR and AI Act compliant. You retain control over access, conversations and the actions carried out by the agent.

Follow-ups move forward. Your team keeps the decisions.

In a small business, every customer reply calls for a next step. Here is how your agent and your team share the work.

Illustrative examples of customer replies

A promise to follow up

“I’ll pay you on Friday.”

The agent records the promised date and adjusts the next reminder. It tracks the commitment without treating a promise as a payment received.

A payment plan to approve

“Can I pay in three instalments?”

The agent prepares a proposed payment plan. Your team approves it before it takes effect; the agent then follows up on the agreed instalments.

A dispute to resolve

“The invoiced amount does not match the quote.”

The agent flags the dispute and passes the conversation on in a task. Your team decides with the relevant context; actions that conflict with the dispute are paused.

You choose which clients to hand over to the agent.
You can pause follow-ups and take over a case.
Sensitive decisions come back to you with the context.

Average results observed across our customers

Results that show up in cash flow.

“Our customers reduce outstanding receivables by 42% on average after 6 months. They also report 86% fewer manual tasks and payments received 19 days sooner.”

in outstanding receivables after 6 months: −42%
fewer manual collection tasks: −86%
sooner to receive payment: 19 days

Averages observed across our customers; results vary by portfolio and starting practices. Fewer manual tasks counts the follow-ups written by the agent that a person would otherwise have written.

Illustrative example: an SME carrying €250,000 in outstanding receivables that cuts it by 42% frees up €105,000 in cash. Invested at 4%, it would earn around €4,200 a year, to set against the subscription price.

Start with the clients you choose.

Review a few accounts with your team before activating follow-ups. You can then expand the portfolio entrusted to the agent.

Portrait of Jean-Marc Langiano — Two years together for simpler, more effective and better-managed collections

We have now been working with Billabex for two years, and the solution has genuinely changed how we manage collections.
What used to be a time-consuming task has become much simpler and almost a formality. We have clear, effective indicators that make it easy to track our outstanding receivables and actions.
The Billabex team is also responsive, available and always ready to listen. We have saved time, improved our organisation and made collections much more effective.
I recommend Billabex without hesitation.

Frequently Asked Questions

The essentials before handing your follow-ups to the agent.

A connected AI can run your workflows. Billabex’s value lies in the follow-up you delegate: continuing the conversation, tracking the promised date, holding a reminder when a transfer is reported and requesting verification. Your team sees what needs checking and which decisions to make; Billabex maintains the system. The agent acts as an identified third party through Revoptim, within the agreed tone and boundaries. Claude or ChatGPT can also read from and act through Billabex via MCP, subject to granted permissions.

Every message written by the agent goes through an automated check, which is not AI: amounts, dates, invoice numbers and required statements are compared with your invoice data, then checked again just before sending. If anything differs, the message is rewritten; if the difference remains, nothing is sent and the account is paused for review. Sensitive decisions, such as a payment plan or a commercial concession, remain yours.
