From quote request to invoice, with no re-entry.
erp4.us is an ERP for SMEs, manufacturers and subcontractors that produce to order: it follows your quotes, orders, production runs and invoices, and handles the requests that arrive by email.
The office floor, today.
Quote requests arrive by email, with drawings attached. Estimating takes time, and every re-entry is a chance for error.
Between the accepted quote and the invoice, information moves across several tools, spreadsheets and inboxes.
Unanswered quotes and unpaid invoices get chased too late — or not at all.
What erp4.us does.
A continuous flow
Quotes, orders, manufacturing orders, delivery notes, invoices: each document follows the job, with no re-entry, and the tasks to do are generated at every step.

Your emails work for you
A quote request arrives by email: the customer is identified, the drawings are retrieved, the quote is created with the documents already attached. Your suppliers’ offers are detected the same way.

AI that helps, without deciding for you
Estimating is assisted by suggestions drawn from your own quotes. You validate, you correct, and the tool learns from your corrections.

What erp4.us does — and what it doesn’t.
erp4.us is built for the office of industrial SMEs, not the shop floor.
erp4.us handles the office
What it does.
- Quotes and estimating
- Sales orders
- Purchasing
- Manufacturing orders and checklists
- Delivery and invoicing
- Documents and drawings
- Tasks and reminders
This is not a shop-floor MES
What it doesn’t do.
No physical stock management, no scheduling or load planning, no time tracking, no quality management (NC/PPM), no maintenance or after-sales service. If that is your main need, erp4.us is not the right tool — and we’d rather tell you before the demo.
Already equipped for the shop floor? erp4.us can work alongside it: it exposes a documented API and webhooks.
Ready for e-invoicing.
E-invoicing is becoming mandatory: receiving for all companies and issuing for large companies and mid-caps from 1 September 2026, then issuing for SMEs and micro-businesses in 2027.
erp4.us issues invoices in Factur-X format, with legal numbering, credit notes, partial payments and automatic reminders, and connects to a dematerialisation platform (PDP).
Deadlines and what changes for you →See the product, not a brochure.
erp4.us is young: we won’t show you invented testimonials. Instead, we show you the real product, on your own cases: a quote request by email, an estimate, an invoice.
Light or dark, your choice.
The application displays in light or dark mode, following your choice or the default setting of your computer or browser.
Works on computer, tablet and phone, with nothing to install.
Watch in hand: a 30-minute demo.
With one of your own quote request emails, if you like.
