Multi-integration agent: your CRM and your ERP, linked
Between the CRM and the ERP, data often travels by hand: you re-key, you copy across, and you find the discrepancy three weeks later. Your agent reads in both systems, matches what needs matching and prepares the writes — stating, for each one, what it rests on. Hosted in France: your operational data stays with you. Every write is approved before it is applied, and stays reversible.
Updated on
Three categories of discrepancy: contact details that differ, an order present on one side only, a status out of step.
For each case, the write proposed and the source used — you see which system prevails and why.
🔗 Sourced · every write states its source
They will be applied once you approve, and stay reversible: every change is logged with its original value.
✎ Action · writes approved, then reversible
A Blue Lemon Agent multi-integration agent links your CRM and your ERP: it reads in both, matches the records and prepares the writes, stating for each one the source used and why. Every change is approved before it is applied, logged with its original value, and therefore reversible. It runs on local inference or is hosted in France: your operational data is entrusted to no one, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.
These figures describe our offer, not results measured at a client. How large the gain is on your number of systems and volume of records is confirmed by a pilot.
What does an AI agent bring to how your data moves?
Between two systems, data drifts out of step silently. Continuous matching, with the source of truth stated, avoids finding the discrepancy too late.
! The issue
Moving data between two systems means settling one question at every discrepancy: which one prevails? The agent matches continuously, presents each divergence with the source it uses and the reason, and prepares the corresponding write — so that synchronising becomes a documented decision rather than blind re-keying.
✓ Our answer
Nothing is written without your agreement, and nothing is irreversible: every change is logged with its original value, which makes it possible to go back. That is the condition for automating between two production systems without fear. Local inference or an isolated resource hosted in France: your operational data passes through no third-party service.
The data your CRM and your ERP share: sovereignty & compliance
The data your CRM and your ERP share describes your entire business. Here is how the architecture of our agents protects it.
Local inference
The agent can run on a machine belonging to your organisation: no operational data leaves the network, no record passes through a public cloud.
Hosting in France
Otherwise, a dedicated and isolated resource hosted in France, under French law — your systems and the data that moves between them: processing and access within the European Union targeted by the architecture.
Reduced extraterritorial exposure
For the data your CRM and your ERP share, 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 systems.
Writes recorded and reversible
Every change is logged with its original value and can be undone; encryption, role-based access and a write scope limited to what you authorise.
AI Act: governed deployment
The agent is strictly in support; no write is applied without approval, no change is irreversible; 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.

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.
· Forty-one operations were left half written. The first system accepted, the second refused. Nobody knew.
· A price differs between CRM and ERP on three per cent of references. I overwrote nothing.
· Fourteen hundred writes were produced by twelve real changes. Two systems were answering each other.
· I am asked to synchronise the free-comment fields. I do not. morning-watch_4-flags.pdf41 half operations · 1,400 writes for 12 changes
⛓ Source · 4 systems, 62,000 writes, synchronisation log
What I record: 41 operations wrote into the first system and failed in the second — a missing mandatory field, an unknown reference, a system momentarily unavailable. An order remains on the CRM side with no counterpart in the ERP.
Why nobody sees it: each system is consistent with itself. The inconsistency exists only between the two, and neither has any reason to look at the other. Of the 41, the oldest was five months old.
What I now do: I write first where I know how to undo, and last where I do not. When the second write fails, I undo the first and flag it. When neither can be undone, I write nowhere and hand over.
What it costs: operations that do not complete and that a human picks up. This month: 23.
What it avoids: a state nobody can see and everybody believes to be sound. An operation that fails outright can be recovered; a half-done one is discovered at stocktaking. 41-operations_5-months.pdfA half-done operation is discovered at stocktaking
⛓ Source · 41 partial operations, oldest 5 months, 23 picked up
What each write carries: the source system, the value's date, the operation that triggered it, and what is needed to undo it where the target system allows.
Routing follows who can settle it: a divergence between systems goes to whoever owns the field, with no write; a partial write is undone, then flagged; a synchronisation loop is cut immediately, before anything else; an out-of-scope field is never carried.
With a monthly summary: operations picked up by hand, divergences per field, loops detected, and the volume of writes against the number of real changes.
What that gives you over the month: 41 half-written operations caught up, one of them five months old; a loop producing 1,400 writes for 12 real changes cut; and the 3% of references with a diverging price put in front of whoever owns the field.
What you gain from tomorrow: no more rekeying between CRM and ERP, no more gap discovered three weeks later, and a stocktake that stops revealing orders with no counterpart. That leaves 23 operations picked up by hand in the month: each arrives with its source, its date and its original value, and is settled in minutes.
And I write into your systems the moment you give me the mandate: in writing, field by field, with the source of truth declared, a daily ceiling on writes and an end date. Every write keeps its original value, so it can be undone; everything is logged; the mandate is withdrawn with a single word, and I am back to preparing within the second. Free-text fields enter a mandate only if you put them there in black and white: they carry what nobody planned for.
The next step is ready: fifteen minutes to map your gaps, declare your sources of truth and set the ceiling of the first mandate.
✎ Framework · no arbitration between values · no free-text field carried
What I record: across shared references, 3% carry a different price in the two systems. The gap runs from a few cents to 18%.
What I could do, and it looks reasonable: take the most recent value. It is almost every connector's default rule — and it is wrong here: the CRM is updated continuously by the sales team, the ERP by a monthly import. The most recent is almost always the CRM's, and the ERP is what stands for invoicing.
What that would have produced: a clean, automatic convergence, and invoices aligned on prices nobody approved.
What I do: I block synchronisation of the field, I list the divergent references with both values and their dates, and I ask which system stands for this field — the question had never been put explicitly.
What that gave: the answer differed by field. The ERP stands for price and stock, the CRM for address and contact. Once written down, the 3% resolved in a single pass. 3-percent_gap-18-percent.pdf"Most recent wins" is almost every connector’s default
⛓ Source · 3% divergent references, gap up to 18%
What I record: a change in system A triggers a write in B; B treats that write as a change and sends it back to A; A receives it, finds it different by a formatting detail, and sends it back. Twelve real changes produced 1,400 writes over eleven days.
What kept the loop alive: a detail — a date written with the time zone in one system and without it in the other. On every round trip the value came back slightly different. Neither system was at fault.
What it cost: no visible error, but both records' histories became unreadable — 1,400 modification lines where there should have been 12, and it is no longer possible to say who changed what.
What I do: I mark every write I produce, and I never react to my own write. A change coming back without having passed through a human or another system is ignored, and counted.
What I now watch: the ratio of writes to real changes. Above three to one, I flag it before the history is lost. 12-changes_1400-writes.pdfNeither system was at fault
⛓ Source · 12 changes, 1,400 writes, 11 days
What I see on looking at them: across a sample of CRM comment fields, one finds call notes, appraisals of the people dealt with, health circumstances mentioned to explain a delay, and payment details copied by hand.
Why carrying them makes everything worse: that content already exists, and that is a problem in itself. But the CRM comment field is seen by five people; the ERP's is seen by accounting and logistics. Synchronising means widening the audience of content nobody has reviewed.
What I do: I carry only the structured fields declared in scope. A free-text field stays in the system where it was written.
What I flag, without the content: to whoever handles data protection, that these fields contain categories of data not provided for there — citing no example, naming nobody, and keeping no copy.
What I propose: if the information must travel, give it a field. A reason for delay in a field designed for it is data; the same reason in a comment is text nobody controls. no-free-text-field.pdfThe same content, seen by five people or by two departments
✎ Framework · no free-text field carried · flagged without content
What I record: over eleven months, 7 interruptions — unannounced maintenance, call quota reached, network failure. The longest lasted 4 hours.
What I do instead of a retry loop: I stop after three spaced attempts, I keep the queue of what did not go through, and I flag it — with what is waiting and since when. A system refusing my calls sometimes has good reasons, and insisting turns an unavailability into an incident: during the 4-hour outage, a retry loop would have produced 9,000 attempts.
What I have already done to the queue before showing it to you: I took each waiting operation and set it against the current state of the other system, because four hours later some no longer apply — an order cancelled meanwhile, a customer who called back. Across the 214 operations from that outage: 176 are unchanged and replayable as they stand, 31 have become moot, 7 are in conflict — the value moved on both sides. Each carries its before value, its after value and which system moved.
The replay is signed, and it takes minutes: the 176 in one click, the 31 set aside in another, the 7 conflicts one by one with the question stated in a single line — which system prevails? Replaying blind would write stale facts into an up-to-date system; replaying this way leaves nothing behind. 7-interruptions_9000-attempts-avoided.pdfReplaying blind writes stale facts into an up-to-date system
⛓ Source · 7 interruptions, longest 4 hours
What I write alone when you open it: creations whose source identifier is kept — which is what allows finding and undoing —, field updates whose source governs unambiguously, and resuming operations left half written. Your 41 half-written operations all fall into that last case: the first system had accepted, the second refused, and nobody knew.
What I require before writing, and that protects you: that the write carries its source identifier, that the matching deletion exists, and that an identical replay does not create a duplicate. Without those three, a creation is an act you do not come back from.
What I do not settle, even with writing open: which system is right when two contradict each other. Across your shared references, 3 % carry a different price depending on the system. Choosing means deciding a price — and I bring it to you with both values and their last-modified dates.
What I have already stopped on my own: a loop of 1,400 writes for 12 real changes, where two systems were answering each other, each believing it was receiving something new. reversible-writing_3-conditions.pdfThe 3 technical conditions · what still escalates · the loop stopped
⛓ Source · 41 operations resumed, 3 % divergent prices escalated, 1,400-write loop stopped
What is kept: each write's identifier, its source system and its target, the timestamp, the result returned by the target system, the operations left incomplete and the exact state where they stopped, the divergences between systems with both values, and the interruptions with their cause.
Why the exact state of an incomplete operation is the most useful item: a blind replay rewrites what was already written. Your 41 half-written operations could not be resumed without that detail — which is why they had stayed as they were.
What never crosses: free-text fields. A comment contains what nobody anticipated, and carrying it makes it visible to people who had no access to it. That rule does not depend on a setting: it is not a matter of trust, it is that the destination has different entitlements from the source.
What I do if a system goes down: I stop everything and resume nothing on my own — 7 interruptions in eleven months, and an automatic resume after an outage is the surest way to double the partial writes. what-you-keep_integrations.pdf6 items kept · the exact state, what makes a resume possible

A prepared and motivated entry, line by line: reference AX-4471, field sale price, value before €149.00 in the CRM, value after €162.50, source retained: the ERP, reason: the price was changed there on 14 March by the pricing team and the CRM never received the update. Every entry I write carries those five elements — field, value before, value after, source retained, reason. Of the 312 entries prepared this month, 312 are motivated: an entry without a reason does not go out.
The audit log, and what it makes possible: I keep the original value of every change, its timestamp, the system it came from and the system that accepted it. Reversibility follows from it: asking to roll back one entry, a batch or a whole day restores the original values, and the log keeps the trace of the rollback itself. A batch of 312 entries is undone in 40 seconds, against half a day of re-keying when the original value was not kept.
The figure that does not flatter me: in June, 9 entries out of 288 were undone by your administrators — 3.1 %. I read all nine back: eight came from the same rule, the one that gave the ERP precedence on the delivery address, when it is the CRM that your sales team keeps current. The rule was mine, so was the error. I rewrote it field by field rather than system by system; of this month's 312 entries, one was undone. The log is not only there to go backwards: it is what told me which rule was wrong, and I put it to you signed or amended.
