The verdict in three sentences
When sales administration spends its days answering "where is my order?", a B2B customer account connected to the ERP is the most profitable item on your digital roadmap. For 20,000 to 55,000 EUR excl. VAT, customers check the status of each order themselves, backorders with their expected delivery date, their invoices and parcel tracking. With a cost per call of 5 to 9 EUR and 40 to 60% fewer calls, payback is measured in months, not years.
The hidden cost of "where is my order" calls
The sales administration director at a French components or cleaning-products manufacturer knows this flow well: 400 calls and emails a week, most of them about an order status, a backorder, a delivery date or an invoice copy. Each request ties up an assistant who opens the ERP, checks the carrier, sometimes calls the customer back. Full cost observed in 2026: 5 to 9 EUR per call depending on duration and loaded salary.
| Contact reason | Share of calls | Average duration | Self-service ready |
|---|---|---|---|
| Order status | 35% | 4 min | yes |
| Backorder and expected date | 20% | 6 min | yes, if the ERP computes the date |
| Carrier parcel tracking | 15% | 5 min | yes |
| Invoice or credit note copy | 12% | 3 min | yes |
| Account statement and due dates | 8% | 5 min | yes |
| Complaint, quality dispute | 10% | 12 min | partly (case submission) |
On 400 weekly contacts, about 20,000 a year, an average cost of 7 EUR adds up to 140,000 EUR annually. Removing half of these calls frees about 70,000 EUR of sales admin capacity, which can go to quote follow-up and key account service.
What a B2B customer account includes in 2026
| Scope | Features | 2026 budget excl. VAT | Timeline |
|---|---|---|---|
| Core consultation | multi-user accounts, order list and detail, statuses synced with the ERP | 20,000 to 28,000 EUR | 8 to 10 weeks |
| Backorders and forecasts | backordered lines, expected delivery date, customer email alerts | + 6,000 to 10,000 EUR | + 3 weeks |
| Invoices and accounts | PDF copies, account statement, due dates, card or transfer payment | + 5,000 to 9,000 EUR | + 2 to 3 weeks |
| Carrier tracking | tracking numbers, real-time status via carrier APIs | + 3,000 to 6,000 EUR | + 2 weeks |
| Complaints and returns | guided form, attachments, case tracking | + 4,000 to 8,000 EUR | + 2 weeks |
| Hosting, maintenance, support | monitoring, backups, minor changes | 400 to 1,200 EUR per month | ongoing |
The item that moves the budget most is the ERP connector. With Sage 100, Cegid or Odoo exposing a decent API, syncing orders and invoices costs 5,000 to 9,000 EUR. With an older ERP without an API, you need a staging database fed by scheduled exports, 10,000 to 18,000 EUR. If you are preparing for France's mandatory e-invoicing, the customer account can also show the status of each invoice sent through your approved platform.
Conditions for success
A customer account only absorbs calls if its data is accurate. The expected delivery date for backorders must come from the ERP (restocking or production completion date), not from manual entry. Sync must be at least hourly, ideally real time for shipping statuses. Adoption must also be driven: a message on order confirmations, a link in assistants' email signatures, and a standard reply pointing to the portal. Allow 3 to 6 months to reach 50% active customers.
Mini case study
Claire Morel, sales administration director at an industrial cleaning-products manufacturer near Lyon, handles 400 contacts a week with 6 assistants. The chosen project combines core, backorders, invoices and carrier tracking for 46,000 EUR excl. VAT, Sage 100 connector included, plus 800 EUR a month of maintenance. After six months, calls drop by 52%, about 10,400 contacts avoided per year at 7 EUR, or 72,800 EUR of freed capacity. One assistant in six moves to following up unsigned quotes. First-year cost: 55,600 EUR. Payback in about 9 months, not counting fewer disputes over backorders.

FAQ
Do we need a B2B e-commerce site to have a customer account?
No, the customer account can be standalone and limited to tracking, for 20,000 to 28,000 EUR excl. VAT. Ordering can be added later without rebuilding everything.
How many customers make it worthwhile?
Below 100 tracking calls a week, the gain stays modest, around 15,000 to 25,000 EUR a year. Above 250 weekly calls, the project usually pays for itself in under a year.
Is the data secure?
Each user only sees their own company's orders, with optional strong authentication and an access log. Hosting in France and GDPR compliance are included in the quote.
Can we handle several delivery sites per customer?
Yes, a group customer can have several delivery accounts and per-site permissions. Allow 2,000 to 4,000 EUR excl. VAT of extra configuration for a complex hierarchy.
How long until a first launch?
The core consultation goes live in 8 to 10 weeks. A full scope takes 14 to 18 weeks, ideally rolled out in waves of 20 to 50 pilot customers.
