Marketplace and channel volume does not fail your ERP in accounting. It fails it at intake, at reservation and at the picking floor. We build that contour as its own system, leave your ERP as the ledger, and your team works a real day in it in week three. Accept and pay, and it moves to your server: your code assigned to you, the foundation licensed with no expiry, and a written requirement still a day of work.
No call. No card. A working day in the system, three minutes.
Three weeks does not buy your whole business, and any vendor who says it does is selling you an argument at the acceptance meeting. It buys one complete contour, working, on your data. The rest are further contours at the same price and the same three weeks each, in the order you choose.
At the end of week three your team works a real day in it, beside the old system. If they cannot, everything you have paid comes back within 14 days.
All of these are built. They are listed here as separate contours because sequencing them is your decision, not ours, and because accounting should be the last thing to move, never the first.
Sign in as the person whose job you want to check. Sales sees orders and margin, the warehouse sees the pick in front of it, purchasing sees what is at the dock, finance sees what can be sent to SDI tonight. Same system, four different days.
Follow SO-1003 from the channel to the invoice without leaving the document. Margin per line is computed, not typed.
PICK-441 on a full screen scan view with no application chrome, forty eight pixel targets, and a keypad for when the gun is flat.
INV-3001 with its journal items and its SDI lifecycle, and the ledger it lands in.
The reason a three week build is possible at all is that we do not migrate your accounting, your history or your fiscal setup. Your ERP keeps being the book of record. We take the operation off its back.
Odoo, SAP, an old local package, it does not matter. Documents flow back to it, and your accountant keeps working the way they work today.
One intake door per channel, defaulting to off, so nothing arrives until you deliberately open it. Product data from your PIM, labels from the carrier you already use.
E-invoicing, delivery documents and archiving, in the interface rather than in an inbox, with a hash chained audit trail underneath. Proven end to end on the Italian chain, built the same way for yours.
Your technical people will ask harder questions than your buyers will. These are the answers we can put a number on.
Adding people should not cost you anything, and it does not: the licence is not counted per user. What costs money is building it and running it with you.
After acceptance and full payment: deployed to your server, your code assigned to you, the repository in your account, the foundation licensed with no expiry. The two-day probe that produces the scope runs under a signed mutual NDA, at no charge. If your team cannot work that real day at the end of week three, everything you have paid comes back. Accept, and the money-back window closes.
Keeping it running and monitored, backups, security patches, every foundation update for this vertical, email support, and changes within a monthly allowance set in your agreement; anything beyond it only on a written estimate you approve. Stop it and the system keeps running. Updates stop unless you take the updates-only plan at €250 per month per contour, billed annually, and security fixes stay free for at least five years.
Sign by 30 November 2026 and the whole first year costs €10,000 instead of €16,000: months seven to twelve of running are on us. Year two is €12,000 on the monthly, and the system keeps running if you stop it.
Four roles, a full day of documents, and one order that goes all the way through. If that does not answer your question, book the call and bring your hardest one.
