eFact: flat-fee invoicing goes digital
For years, Wallonia invoiced its flat fees to health insurers on paper. With eFact and the rollout of WalCareNet, that era is ending. Here is what changes in practice for your MR, MRS or day-care centre.
The monthly invoicing circuit: Resident (Katz flat fee O→D) → Nursing home (monthly statement) → eFact (secure flow) → Insurers / OAW (monthly payment). In 2026, the regional part moves to WalCareNet; the federal part keeps running via MyCareNet.
The digitalisation of nursing homes reaches a new milestone. After the paperless insurer agreement via eAgreementLight, it is now flat-fee invoicing's turn to leave paper behind. In Wallonia, this shift accelerates sharply in 2026 with the ramp-up of WalCareNet, the Region's own exchange channel. For MR, MRS and CSJ directors, the time to prepare is now.
Invoicing your flat fees: a vital process… still largely on paper
Every month, your facility sends the health insurers a statement of the flat-fee intervention due for your residents: a summary expense note plus individual expense notes, computed from each resident's Katz dependency category. This flow funds an essential share of housing and care. Rigour is the rule, and the slightest error costs you cash flow.
Electronic flat-fee invoicing has been possible since 2011. Yet in practice, a large majority of Walloon nursing homes still send their invoices on paper — whereas Brussels generalised electronic invoicing long ago. This paper workflow has a real, daily cost:
In a sector where every admin hour counts, this circuit has become untenable. Digitalising invoicing is no longer a comfort: it is a matter of financial steering.
eFact: insurer invoicing goes digital
eFact is the electronic third-party-payer invoicing service that connects your nursing home to the health insurers via the MyCareNet network. The nursing-home sector uses its standard version. In practice, your monthly statement no longer goes by post, but:
The result is tangible: fewer rejections because checks happen upstream, payments that come in faster, and a complete, dated history of every exchange.
An often-forgotten argument: INAMI pays a one-off €800 bonus to nursing homes that invoice electronically.
MyCareNet and WalCareNet: the Walloon dual circuit
This is the Walloon specificity you absolutely need to understand. Since the 6th State Reform, part of nursing-home funding is a regional competence, the other part federal. Wallonia therefore built its own exchange channel, WalCareNet, live since 1 January 2025. The concrete consequence for your invoicing:
MyCareNet — federal part
Services under INAMI's competence keep flowing through MyCareNet, as they do today.
WalCareNet — regional part, 2026
From 1 January 2026, regional-competence services must go through WalCareNet — monthly electronic invoicing and eAgreement Light to the Walloon insuring bodies (OAW) are deployed there.
Good news: this dual circuit is invisible to a well-equipped admin team. The software is what must route each service to the right channel. Provided it is accredited for both. This transformation involves several players:
AViQ — WalCareNet
The Agency for a Quality Life steers WalCareNet and the Digi MRS project, and publishes the invoicing calendar and instructions for Wallonia.
National Intermutualistic College (CIN)
Coordinates all health insurers around a common third-party-payer invoicing framework via MyCareNet.
The Walloon insuring bodies (OAW)
Recipients of the invoices on the regional side, and partners in the operational rollout.
INAMI
Computes the flat fees on the federal side and pays the €800 bonus tied to electronic invoicing.
What concrete benefits for your facility?
Beyond the talking points, here is what eFact changes in the daily reality of an MR/MRS director and their admin team:
Faster cash flow
No more postage or postal transit days: the flat fee comes in faster and more regularly.
Fewer rejections
Consistency checks happen at the source, before sending. You fix before, not after.
Audit-ready
On inspection, you hold a complete, dated, defensible history of every statement.
Admin time given back
No more repetitive keying and printing: the team focuses on analysis, not data entry.
Prepare your move to eFact now
eFact will not stay optional for the Walloon part. To prepare calmly, we recommend four concrete actions:
Bottom line: eFact is only one link in a wider transformation — synchronous insurability, eAgreementLight, digital resident record, Katz assessments, automated INAMI/AViQ invoicing. Plan your facility's software ecosystem as an integrated whole rather than stacking isolated tools. The legal obligations themselves do not change: only the channel is modernised.
