YOUR TOOLSFINALLY TALKTO EACH OTHER.

Accounting, POS, carriers, payment, marketplaces, booking: I connect your programs to each other by API, export or webhooks. No more re-typing, no more Sunday-evening exports, and alerts if something breaks.

Typical cases

Bridges that save hours.

01

Store → accounting

Every paid order creates the invoice in Axonaut or Pennylane, with the right customer, the right lines, the right VAT. No more monthly export by hand.

02

POS ↔ store

The POS stays master of the stock; the store updates every 15 minutes; web sales flow back into the POS. No more overselling.

03

Orders → carrier

Label generated as soon as preparation starts, tracking number sent back to the customer, status updated on the carrier's webhook.

04

Booking ↔ POS

A restaurant booking creates the table and the deposit in the POS; cancellation releases it. Booking, no-show and payment in the same place.

05

Marketplaces → single tool

Amazon, Cdiscount, website: all orders in the same queue, same picking slips, same invoice.

06

Form → CRM → quote

A request on the site creates the contact, triggers the follow-up, prepares the pre-filled quote. The salesperson only has to approve.

How I do it

Reliable, monitored, reversible.

API first

When the tool has an API, we use it properly: authentication, quotas, error recovery, idempotency (no duplicates if it replays).

Otherwise export / import

FTP, CSV, iCal, email: many POS or accounting programs only have that. It can be made reliable too, with checks and alerts.

Webhooks & queues

Events (payment, shipment, cancellation) trigger actions in real time, with a retry queue if the other side is down.

Log & alerts

Every sync is traced. If something fails, you and I know before your customer.

Sandbox

Everything is tested on the vendors' test environments before touching production. Gradual switchover.

Signature & security

Secrets kept out of the code, HMAC signatures, key rotation, least privilege. Your accounting access does not lie around in a file.

Indicative price

A simple bridge (scheduled export, one-way sync) starts at 900 €. A two-way sync with recovery and alerts is priced at scoping. Monitoring included in maintenance.

FAQ

Frequently asked questions.

My accounting software has no API, is it hopeless?+
Rarely. Most accept an import (CSV, FEC, PDF invoices with metadata). We automate the generation and the upload, with checks.
Who manages the access keys to my tools?+
You. I guide you to create dedicated, limited-rights, revocable access. They are stored encrypted on the server side, never in the code or by email.
What happens if a tool changes its API?+
The log and the alerts detect it. Under maintenance, the adaptation is included in the hours credit; otherwise, a quick quote.
Do you work with my accountant?+
Yes, it is often they who define the expected format. A 20-minute exchange avoids weeks of back and forth.
