Collect invoices without effort
The accounting software is connected, and invoices and due dates flow in on their own. An AI-assisted import (PDF, image, Excel, CSV) serves as a fallback.

What Relanzy does
Three things, done well
Chase under your own name
Reminders go out from your own mailbox (Gmail, Microsoft or SMTP), not from a third-party service. To your customer, it is you writing, with the tone and pace you chose.
Escalate within French law
Late-payment penalties and the €40 fixed recovery fee are calculated, then a formal notice is generated as a PDF when the amicable route is not enough.
Smart Reply
AI reads your customers’ replies
When a debtor replies, a language model classifies the reply in real time and the case reacts accordingly.
Every classification shows the model’s confidence level. A person decides what happens next whenever the customer relationship is at stake. We do not publish usage figures until the sample is significant.
- Payment promiseThe sequence is paused for a few business days.
- Request for more timeThe sequence is paused for longer.
- DisputeThe sequence stops and you are alerted first.
- Payment announcedYou are asked to check and mark the invoice as paid.
- Document requestThe sequence is paused while you reply.
- OtherThe reply shows in the thread, with no automatic action.
Field notes
What production taught us
Lessons from our own products, the kind you do not find in the documentation.
A partner API’s identifiers are text, not numbers.
Some identifiers exceed the integer size JavaScript can represent without loss. Converted to numbers, they round silently and the sync links the wrong invoice. We store them as text, end to end.
Status beats remaining balance.
An invoice marked as paid can still show a non-zero amount due in the API response. Trusting the amount would chase a customer who has paid. Reminders stop on status, never on a zero balance.
A misclassified reply costs more than a missed reminder.
Before the model classifies anything, safeguards set aside risky cases: no-reply addresses, out-of-office replies, disputes already open. A case in dispute is never downgraded by a later reply.
A test environment must never be able to touch production.
A test suite pointed at the live database by mistake created ghost accounts there. Since then, the code refuses to start unless the database is explicitly allowed: the safeguard is designed to fail closed.
A business domain belongs to the company, not to its director.
Our first publisher verification request to Microsoft was rejected: the domain was registered to a person, not to the company. We transferred it before resubmitting. Check this before any platform certification.
For your projects
What the Labs change for you
We know the traps
Identifiers, duplicates, expiring tokens, contradictory statuses: we have hit them before your teams do.
We know what a model holds up to in production
Safeguards, confidence levels, controlled costs, human decisions where they are needed: none of this shows in a demo.
We have been through certification
App verification by Google and Microsoft, connector certification by a partner platform: we know what they ask for.
Describe the situation in three lines.
The context, the deadline, what is blocking. We reply within two business days. If we are not the right people for it, we will tell you.
