Unpaid invoice chaser: your templates, your sequence

Chasing an unpaid invoice takes steadiness and tact: too early and you offend, too late and you lose. Your agent tracks the due dates, spots the invoices to chase and prepares the letter at the right stage of the sequence, in your tone. Hosted in France — local inference or an isolated resource — your customers' financial position stays confidential. Nothing goes out without your approval, or without a written sending mandate for amicable follow-up you withdraw in one move: a misplaced chaser costs a customer.

Which invoices need chasing this week?
Overdue invoices picked up under your settings, sorted by the stage reached in your sequence.
For each: the corresponding template is pre-filled with the invoice reference, the amount and the due date.
Two files have an open dispute: I have kept them out of the chasing sequence.
✎ Action · letters prepared — nothing goes out without approval or a written mandate
Why did you set those two aside?
A credit note is in progress on the first, and the second is subject to an unresolved complaint.
Chasing in those circumstances would be counter-productive: I flag them to you rather than handling them like the rest.

✦ In brief

A Blue Lemon Agent chasing agent tracks the overdue invoices, places each file in your chasing sequence and prepares the corresponding letter from your templates. It sets aside the files under dispute or subject to a credit note rather than handling them mechanically. It runs on local inference or is hosted in France: your customers' financial position is entrusted to no one, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity. Live within a few weeks,.

AI model: none of the AI models offered currently carries a fixed surcharge. When the selected model carries a cost, that cost is shown when you choose it, before you order, and re-invoiced at the cost incurred, with no mark-up; usage is billed at the publisher's price. Publishers' prices are published in US dollars: the amount re-invoiced is the amount in euros actually borne by Blue Lemon Agent on the publisher's invoice, at that invoice's exchange rate, with no commission or mark-up.
Included components and additional components Components included in the base offer: the Blue Lemon Agent software foundation, the AI models listed in the order journey, the standard channels (Microsoft Teams, Slack, WhatsApp Business, email, website chat, calendars, Microsoft 365 / Google Workspace, file storage, market VoIP telephony, professional social-media pages and accounts, Google Business Profile), hosting for the package chosen, in France by default, backups, supervision, updates and support. If adapting the AI agent to your constraints, your needs or your requests requires other paid components — a third-party publisher's software licence, paid API access to one of your applications, hosting of health data, for which French law requires an HDS-certified host (art. L. 1111-8 of the French Public Health Code), SecNumCloud-qualified hosting, a speech synthesis service, particular hardware —, they are offered to you as an option or on quotation and re-invoiced at the cost incurred; nothing is committed without your written agreement. Where the artificial intelligence model you choose entails an additional cost, that cost is shown to you before you order and re-invoiced to you at the cost incurred, with no margin.

Use cases

What does the agent actually do?

One agent, several moments in tracking receivables, with links to neighbouring agents. The agent carries out by itself what you authorise it to do; you decide what it does on its own and what it submits to you.

Included in your agent The 3 capabilities essential to this promise are included, at no extra cost.
From 259 € excl. VAT / month

Deadline tracking

Picks up the invoices whose due date has passed, under your tolerance rules.

Chasing letters

Prepares the letter at the stage reached in your sequence, in your usual tone.

Setting aside sensitive files

Flags disputes, credit notes in progress and open complaints instead of chasing them.

Controls and safeguards These 4 controls are built into the agent: they frame what it does, whatever plan you pick. They are not chosen and are not added to your order.
Human validation, exceptions and escalation Status, safe closure and audit trail Reconcile supporting documents, rules and accounting entries with an audit trail Handle discrepancies and validations before any accounting entry or payment
What the agent must be connected to This connection is required for the agent to work. It concerns your information system and is scoped during the audit.
Integrate with accounting and banking software and with approved platforms (French e-invoicing)

A scripted demonstration. These exchanges show how the agent behaves — its sources, its refusals, what it leaves to your teams. Nothing is sent from this page, no model is queried here, and the matters named are fictional. That is precisely what we promise your data. The behaviours shown here — monitoring, automation rules, routing and reminders — are configured with you during deployment, from your tools, your rules and your thresholds. The architecture points named in these exchanges — location, local execution, isolation, encryption, role-based access, logging — are not a guarantee attached to the demonstration: they are those of the architecture set out in your quotation, and verified before commissioning.

Chasing unpaid invoices · hosted in France

Fictional simulation — not a client result

Four settings within reach this morning on your email chasers — each one fixable, and I tell you what each one returns.
· Three chasers went out after the customer had replied, their reply having landed in a mailbox other than the one that triggers the stop. Stopping on all your addresses is an hour's work, and their request, I have handled.
· 41% of your chasers over the last three months were not opened, all sent from an unauthenticated sending address. Authenticated, it drops to 12%: four chasers in ten that finally reach a reader.
· One address has been bouncing since February — 7 sends, 7 bounces, and the invoice stays at "chased" status. A "contact to be found" status and that invoice becomes reachable again.
· One customer received 6 chasers in 11 days on three invoices, from three sequences unaware of each other. One cadence per customer, and that is one message instead of six, with no invoice chased any less often. morning-watch_4-flags.pdf4 flags · 6 chasers in 11 days
⛓ Source · send log, open rates, bounces, live sequences
Three chasers sent after a reply — how is that possible?
Because the reply arrived at a different address from the one that triggers the stop.
What happened: the chaser goes from accounts@; the customer replied to contact@, the address printed on the invoice. The sequence saw nothing and carried on.
What the customer received: they write on 14/07 to say the invoice carries the wrong delivery address. They receive a chaser on the 18th, one on the 25th, one on 02/08. Three messages telling them nobody read them.
Where it stands: the invoice has been waiting for 74 days, and the problem they reported has been waiting with it. Both are settled together, and it is the same move.
What I propose: stopping the sequence on any reply arriving at any of the company's mailboxes, not on the sending address alone. That is a setting, not an instruction.
What I did with their reply, rather than write back: their point is a billing error — they expect it corrected, not answered. So I matched the invoice against the delivery note, isolated the wrong address and prepared the credit note and the corrected invoice, both quantified and dated. Issuing the credit note is signed; it takes thirty seconds, and an invoice unpaid for 74 days becomes payable again. 3-chasers_after-a-reply.pdf1 reply recovered · 74 days · credit note and reissue ready
⛓ Source · customer reply of 14/07, send log, company mailboxes
How did you spot all that? And who do you tell?
I watch, continuously, what you have opened to me: the send log, opens, bounces, replies arriving in your mailboxes, and live sequences.
Routing follows what can be fixed quickly: a sequence that carried on after a reply goes to the account owner, immediately — it is the only case where a customer has already been damaged; a deliverability problem to IT, with the number of emails concerned; a bouncing address to the salesperson, because they have the right contact; an over-chased customer to the account owner, before the next send.
With a chase: 4 h on a sequence wrongly continuing, 7 days on the rest. Then a monthly summary: by cadence and by cause of send failure, never by customer.

What this morning has already earned you: an invoice unpaid for 74 days whose cause is finally known — a customer reply that arrived at contact@ while the sequence went out from comptabilite@ — 41% of your chasers never opened, for want of an authenticated sending address, and 7 sends for 7 bounces on an invoice still marked "chased" since February. From tomorrow: deliverability repaired means four chasers in ten finally landing in front of a reader; a sequence stop on any reply, whichever mailbox it reaches, means a customer chased six times in eleven days no longer is; and a reported billing error gets fixed instead of chased. The access is yours: send log, opens, bounces, replies and live sequences opened by role, logged, withdrawn with a word; your customers' financial position does not leave your walls. Sending is not a prohibition, it is a mandate — written, limited to the templates you have approved, capped by amount and by sequence step, dated, withdrawn with a word: one approval given once for a written perimeter, instead of a hundred approvals one at a time — and any customer reply stops everything, immediately. What the net catches, and how often it tightens: a sequence wrongly continuing comes up within 4 h, a bouncing address gets no eighth send, an over-chased customer is seen before the next dispatch. The next step is ready: the sequence-stop setting across all your addresses, and sender authentication; the first takes an hour, the second depends on your IT — tell me who to approach. amicable-follow-up-mandate_extract.pdf2 reminders · one-move withdrawal · log

The context

What does an AI agent bring to tracking your receivables?

Chasing means tracking every due date and knowing where each file stands. But a chaser sent without judgement damages a commercial relationship for a long time.

! The issue

An effective chaser means knowing the due date, the stage already reached in the sequence and the state of the relationship. The agent keeps those three pieces of information up to date whatever the volume, and prepares the letter at the right stage, in your tone. Files under dispute or subject to a credit note are set aside explicitly, and your receivables and your late payments stay with you rather than with a third-party service subject to the Cloud Act.

✓ Our answer

Assisted chasing is only of interest if it is sovereign and cautious. Local inference or an isolated resource hosted in France, explicit setting-aside of files under dispute, nothing sent outside your approval or your written mandate: you gain steady tracking without risking the customer relationship. It is the collections manager who decides who is chased, and when.

The decisive point

Your customers' financial position: sovereignty & compliance

Your receivables and your late payments map the health of your customer portfolio. Here is how the architecture of our agents protects them.

Local inference

With the 100% Sovereign package, the agent runs on a machine belonging to your organisation: no receivables data leaves the network, no customer history passes through a public cloud.

Hosting in France

Otherwise, with the Agility and Serenity packages, a dedicated, isolated resource hosted in France, under French law: data hosted in France; the AI model is called at its publisher, except with the Sovereign model option.

Reduced extraterritorial exposure

For your customers' financial position, the architecture aims to reduce exposure to the Cloud Act and FISA 702; being located in France or in the European Union does not, on its own, guarantee immunity.

Isolated resource

No pooling: an environment strictly dedicated to your company and its customer portfolio.

Sending under mandate, or approval before sending

Without a mandate, every reminder waits for an authorised person. With a written sending mandate for amicable follow-up — scope, ceiling per debtor, duration, one-move withdrawal, log —, the agent sends the overdue-invoice reminders you have set, in your name, from your address and under your signature, using your templates, to businesses or private individuals as you choose. It collects nothing, replies to no debtor and never sends a formal notice: anything beyond reminders goes back to a person. Sequence and templates are applied as they stand; encryption, role-based access (RBAC) and logging of every letter prepared.

AI Act: governed deployment

The agent carries out what you have authorised; no chaser is sent outside a written sending mandate or an authorised person's approval, no formal notice is sent by the agent and no file is classed as disputed without your view; traceability and human oversight from end to end.

What depends on the architecture chosen These points are not general guarantees: they are settled deployment by deployment, in the quotation.

  • The applicable location is that of the architecture set out in the quotation and verified before commissioning.
  • Local execution is announced only for the configuration explicitly described and accepted in the quotation.
  • The applicable isolation depends on the deployment mode set out in the quotation; no dedicated isolation is presumed.
  • Roles and permissions are configured and accepted for the identities and systems actually connected.
  • The events logged, their content, their retention period and who may access them are defined for the deployment chosen.
For portfolios containing contentious debts or customers in insolvency proceedings, SecNumCloud and reinforced hosting are options depending on your requirements. A single architecture is designed to answer both the GDPR and extraterritorial exposure. Designed for deployment in line with the GDPR and the AI Act, after the processing, roles and context-specific risks have been assessed.
The gain

How much tracking can a team recover on its receivables?

By automating the spotting of due dates and the preparation of letters, tracking becomes steady without taking any more time. How large the gain is depends on your volume and remains to be confirmed by a pilot.

Frequently asked questions

Your questions, our answers

Does the agent send the chasers by itself?
Never without a written frame. By default, it prepares and you send. If you give it, from your customer area, a written sending mandate for amicable follow-up, it sends the overdue-invoice reminders you have set: business or private debtors, number of reminders, spacing, days and hours, templates, duration. You withdraw that mandate in one move. Some limits cannot be set, because the law imposes them on the creditor: no cost or penalty charged to private individuals, stop at the first reply or dispute, no reminder beyond the limitation period, none to a debtor in insolvency or over-indebtedness proceedings. As soon as a debtor replies, the claim leaves the mandate and goes back to an authorised person. The agent collects nothing, replies to no debtor and never sends a formal notice; the mandate covers neither telephone calls nor text messages, which stay approved one by one by an authorised person.
Who answers for the rules of amicable collection?
You do, with your advisers. The rules that govern debt collection and consumer protection are a matter for the company and its advisers: the assistant does not promise the legal compliance of your chasers. It stays within amicable chasing: no formal demand, no penalty calculated by the agent, no enforced collection action, and no message to a debtor without an authorised person's approval, outside a written sending mandate for amicable follow-up limited to overdue-invoice reminders sent in your name and from your address. The agent applies the limits you set and those it cannot lift; it does not collect debts on behalf of others: your company follows up its own invoices.
How does the agent avoid chasing a customer in dispute?
It sets aside the files with an open dispute, a credit note in progress or an unresolved complaint, and flags them to you separately. The final classification of those cases is yours.
Does the agent adapt the tone to the chasing stage?
It applies the template corresponding to the stage reached in your sequence — first reminder, firm chaser. The templates are yours; the agent does not rewrite them and prepares no formal demand.
Is our customers' financial data protected?
Yes. The agent is hosted in France, on local inference or an isolated resource, with the deployment objective of processing and access operated within the European Union and an architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity. Your receivables are not used to train a third-party model.
Does it connect to our accounts?
Yes, to the common accounting and invoicing tools, to read the due dates and the state of payments. The integration is defined at the design stage, with no migration.
How far will the agent chase the same person?
It never goes beyond the sequence you have written, and three stops are built into the configuration: a recorded payment ends the sequence, an open dispute, credit note or complaint takes the file out before the first reminder, and a request from the person not to be contacted again stops it immediately and for good. Without a sending mandate, the agent drafts the letters and you send them; under a mandate, the same stops apply and the number of reminders is the one you set. An automated reminder that repeats without limit on the same person becomes repeated pressure, and the law treats it as such (French Criminal Code, art. 222-33-2-2, aggravated where the medium is digital).
How long does it take to deploy this assistant?
A few weeks as a rule, depending on how complex your chasing sequence is and the accounting integration, after a meeting with our sales team then a phase of design, integration and testing.
Can it send a letter, or a registered letter?
As an option. E-mail is the default channel. If you wish, a reminder can go out by post or by registered letter, lodged in your name with a mailing provider chosen with you; the letter's template is yours, with no formal notice, and the first registered letter waits for your approval unless you set otherwise. Postage stays at your expense, never the debtor's.
