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 is sent without your approval: a misplaced chaser costs a customer.
Updated on
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 automatic chasing.
✎ Action · letters prepared — nothing is sent
Chasing in those circumstances would be counter-productive: I flag them to you rather than handling them like the rest.
✎ Support · exceptions flagged, human decision
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,.
These figures describe our offer, not results measured at a client: how large the gain is on your volume of invoices and the length of your sequence is confirmed by a pilot.
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 automatically: you gain steady tracking without risking the customer relationship. It is the collections manager who decides who is chased, and when.
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
The agent can run 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, a dedicated and isolated resource hosted in France, under French law — your invoices and your customers' history: processing and access within the European Union targeted by the architecture.
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.
Sequence and templates respected
Your chasing sequence and your templates are applied as they stand; encryption, role-based access and logging of every letter prepared.
AI Act: governed deployment
The agent is strictly in support; no chaser is sent automatically 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.

· Three chasers went out after the customer had replied. They had written to report a problem with the invoice; the sequence carried on.
· 41% of your chasers over the last three months were never opened. They all go from the same sending address, which is not authenticated.
· One chaser went to an address that has been bouncing since February — 7 sends, 7 bounces, and the invoice is still marked "chased".
· One customer received 6 chasers in 11 days on three different invoices, from three sequences unaware of each other. morning-watch_4-flags.pdf4 flags · 6 chasers in 11 days
⛓ Source · send log, open rates, bounces, live sequences
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.
What that produced: they stopped replying. The invoice has been unpaid for 74 days and the problem reported was never handled.
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 ignored · 74 days · problem unhandled
⛓ Source · customer reply of 14/07, send log, company mailboxes
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.
✎ Framework · no automatic sequence — approval at each cycle
What happened: three unpaid invoices, three sequences started on three dates. Each respects the cadence: D+7, D+14, D+21. Added together they give 6 messages in 11 days, two of them on the same day.
What the customer receives: not three reminders on three invoices. Six emails from a company chasing them every other day. That is how a cash-flow delay becomes a dispute of principle.
What I propose: a cadence per customer, not per invoice. One message summarising all three invoices, and a single counter. The cadence becomes legible to them and sustainable for you.
What that changes in volume: over three months, your 412 chasers sent would become 287 — and no invoice would be chased less often.
What I have costed so the cadence can be chosen: across your last three months, D+7 gets paid in 19 days on average and produces 412 sends; D+15 gets paid in 23 days and produces only 240. Four days of cash against 172 fewer messages landing on your customers. The cadence is signed — it is a commercial choice, it depends on your sector —, but it is decided on those two numbers, and I apply it the same day. 6-chasers_11-days.pdf412 → 287 sends · no invoice chased less
⛓ Source · 3 sequences, send log, 412 chasers over 3 months
What you approve once: three templates — first reminder, second reminder, final reminder — each with its variables: number, date, amount, due date, contact.
What I add to them: nothing. The variables are filled from the invoice, and the text does not move.
Why I do not adapt the tone to the customer: because it would look like a good idea. A template that hardens on its own when a customer is late produces messages nobody has reread, and the day it hardens on the wrong customer — the one whose invoice was in dispute — you have nothing to answer with.
What I do instead: I flag when the template plainly does not fit. Across the quarter's 412 chasers, 19 went to customers with an open dispute, and the template does not mention it.
What I propose: a fourth template, "invoice in dispute", which you write and you approve. 3-templates_19-dispute-cases.pdf19 chasers on disputed invoices · 1 missing template
✎ Framework · no generated content — your approved templates only
What I record: across 412 chasers, 169 were never opened. A 41% non-open rate on chasers sent to people expecting an invoice is far above what is usually seen.
What I looked at: what became of the sends. 112 of the 169 produced no signal at all — no open, no bounce, no click. That is the profile of an email filed as junk.
What I found: the sending address accounts@ is not authenticated by your domain records, whereas contact@ is. Emails sent from contact@ have a 12% non-open rate.
What I have prepared for your provider, who has only to apply it: the two records missing on accounts@, written out line by line, exactly as they already exist for contact@ at your end. Changing the domain is signed and executed at their end — a record error cuts off all the company's email, not only the chasers. In figures: 41% non-open against 12%, so roughly 120 chasers a quarter that would finally reach a reader.
What I provide: both rates, the 112 with no signal, and the difference between the two addresses. That is what is needed to put the question to your provider — and it is half a day's work at their end. 412-sends_169-unopened.pdf41% against 12% · 112 with no signal at all
⛓ Source · 412 sends, open rates by address, domain records
What I record: 7 sends between February and August, 7 hard bounces — the address no longer exists. And at every send, the invoice moves to "chased" status.
What that produces: the invoice looks followed up when nobody has ever received anything. It never resurfaces among unpaid invoices to handle, because it is always "being chased".
Across all your unpaid invoices: 14 are in that position, for €52,000. Four of them have never received a single message since issue.
What I propose: a hard bounce moves the invoice to "contact to be found", not to "chased". And the salesperson is told — they almost always have the right contact, and nobody has asked them.
Where I go looking for the right contact, and where I do not: in your own exchanges — the signed quotation, the purchase order, the salesperson's emails —, and there I found a valid address for 9 of the 14 invoices. An address picked up somewhere online, no: writing to an address found at random, about an unpaid invoice, means sending financial information to somebody you know nothing about. For the remaining 5, the salesperson has the question ready to answer — they almost always have the right contact, and nobody had asked them. 14-invoices_dead-address.pdf€52,000 · 4 with no message ever received
⛓ Source · 7 bounces, invoice statuses, 14 comparable invoices
· A reply from the customer, at any company mailbox. That is the main trigger, and it is the one missing this morning.
· A payment, even partial. A customer who pays half has acted; chasing them as if they had done nothing cancels the gesture.
· The opening of a dispute, from whatever source.
· A hard bounce. Continuing to write to a dead address fills a log and nothing else.
· A credit note issued to the customer, even unrelated to the invoice being chased.
What I check in addition, just before sending: that no other sequence has written to this customer within 7 days, and that no salesperson has a live exchange with them — that last point is what prevents the message landing mid-negotiation.
What I prepare for a restart, and what triggers it: a stopped sequence stays stopped until a person restarts it, because it stopped on an event somebody must have handled. So I hand the whole file to whoever owns the account: the stopping event, its date, what has been done since, and the restart message already drafted at the right step of the sequence. One word from you and it resumes at the next step, not at the first. 5-stop-triggers.pdf5 stops · 2 checks before every send
✎ Framework · 5 stop triggers · checked before every send
What is kept: the message sent, the sending address and the template used, the date, what became of the send — opened, bounced, no signal —, the reply received, and the event that stopped the sequence.
What is not kept: no responsiveness score per customer, no payment-behaviour history intended to harden the tone, no open-rate profile — knowing a customer opens their email at 7 a.m. serves nothing anyone should want to do here.
Why "no responsiveness score": it would serve to decide who to chase harder. And the customer who does not reply is often the one whose address bounces — the penalty would fall on a technical fact.
What the monthly summary contains: open rates by sending address, causes of send failure, sequences stopped and by what, and the number of messages per customer. Four indicators about the channel. what-is-kept.pdf6 items kept · 3 never produced
✎ Framework · retention periods to be set by the company
Due-date tracking: every night I pick up the invoices past their due date, according to your tolerance rules rather than a general one — 5 working days for a client under a framework agreement, no grace for a one-off sale, 15 days for the 6 public-sector clients whose payment authorisation delay you know. This morning, 184 invoices are past due for €412,000; after your tolerances, 131 enter a sequence, and the other 53 will resurface on their own date with nobody having to remember them.
Setting sensitive files aside: of those 131, 17 drop out before anything is sent — 9 carry an open complaint, 5 are waiting on a credit note agreed and not yet issued, 3 are in a documented commercial dispute. They are not chased: they are flagged to you with the reason, the date the sensitive file was opened and the person following it on your side. Chasing a client who is waiting on a credit note from you is the most expensive chase there is.
What that gives back: reviewing due dates and sorting out sensitive files took 6 hours a week from your accounts receivable team; it now takes 40 minutes of checking. Over 47 working weeks, more than 250 hours given back — more than seven 35-hour weeks, rounded down.
The figure that does not flatter me: of my first 90 exclusions, 4 sensitive files slipped past me — 4.4 % — and those four clients received a chaser after they had written in. All four complaints had come in by telephone and were noted in a free-text CRM field I was not reading. I read it now, and I treat any mention of a dispute, a credit note or a complaint less than 60 days old as grounds to set the file aside, even at the risk of setting one aside wrongly: over the next 240, no misses, and 7 exclusions your accountants lifted in one click.
