Mistakes to avoid in your Kap Numérik application: 10 rejection reasons
23 octobre 2026
A well-prepared Kap Numérik application goes through in a few weeks. A sloppy, mis-ordered or incomplete one gets rejected, and it happens far more often than you would think. In Reunion Island, each year a share of applications is turned down for avoidable reasons, often the same ones.
This article lists the ten most common mistakes, in order of impact, and shows how to defuse them before submission. It is designed to be re-read right before you send your file, like a final checklist.
1. Starting the project before approval
By far the number-one rejection reason. The Kap Numérik only funds services started after the file is submitted and approved by the Region. Any proof of an earlier kickoff, email, deposit, signed quote dated before submission, is enough to disqualify the application.
How to avoid it: sign the quote only after receiving the acknowledgment of receipt, and date every piece explicitly. If the vendor needs a commitment signal before validation, ask for a non-contractual "letter of intent" that has no legal order value.
2. Mistaking submission for approval
Many believe that once the file is submitted, they can start. False. Submission authorises nothing. Only the formal approval from the Region, delivered by mail or notification in your personal portal, opens the right to start.
How to avoid it: wait explicitly for the formal notification. In case of commercial urgency, ask the Region for a fast-track review, it is sometimes possible.
3. Writing a vague quote
A "website" quote at 2 500 € HT, with no detail, won't fly. The case officer needs to see what is being funded exactly: number of pages, features, modules, SEO work included or not, first-year hosting, maintenance, training.
How to avoid it: demand a detailed line-by-line quote with precise labels. A good vendor familiar with the scheme provides this format spontaneously.
4. Mixing eligible and non-eligible spending
In a single quote, some lines qualify (SEO, development, training) and others don't (hardware, multi-year hosting, recurring SaaS). If the case officer cannot untangle the scope, they may reject the whole thing.
How to avoid it: clearly separate eligible from non-eligible lines, or produce two distinct quotes. The grant will then only cover the "eligible" quote.
5. Forgetting FEDER mentions on the deliverable
The delivered site or tool must carry two mandatory logos, European Union and Région Réunion, plus an explicit mention of FEDER co-funding. The absence of these mentions, checked at reimbursement time, is a frequent reason for payment holds.
How to avoid it: include these mentions from go-live, typically in the footer or on a "Partners" page. Official templates are provided by the Region.
6. Changing the scope mid-project
You planned a showcase site, mid-way you decide to add a booking module. Problem: the final invoice no longer matches the approved quote, and the gap can trigger a rejection on the unplanned lines.
How to avoid it: stay strictly within the approved scope, or request an amendment to the file before committing the extra spending. An amendment is usually accepted if it stays within the cap.
7. Choosing an unstructured vendor
The vendor must be a professional entity, with a SIRET number, ideally familiar with FEDER. Under-the-table providers, non-invoicing freelance platforms outside France, or friends without a legal structure won't pass.
How to avoid it: ask the vendor for their SIRET number, an example of a Kap Numérik invoice, and check that they can provide the commitment sheet and FEDER mentions.
8. Mis-preparing administrative documents
An outdated Kbis, a RIB in a personal name instead of the company's, an illegible revenue certificate: each missing or invalid piece adds weeks of back-and-forth with the case officer, and can lead to a rejection for "no reply within deadline".
How to avoid it: gather all pieces before submission, checking validity dates. Minimum checklist: Kbis or SIRENE record < 3 months, company RIB, latest tax return or revenue certificate, up-to-date statutes for non-profits.
9. Overlooking the payment lead time
Even after reimbursement approval, the payment can take 2 to 6 weeks to arrive. Businesses that count on this payment to pay the vendor find themselves in a cash crunch.
How to avoid it: treat the Kap Numérik as a deferred reimbursement, not an advance. Plan the matching cash before signing the quote.
10. Not responding to case-officer requests
During the review, the service may request an additional piece, a clarification, a quote correction. These requests have short response windows, often 15 working days. No reply, and the file is closed for "failure to respond".
How to avoid it: check your personal portal regularly, and enable email notifications when available. If more time is needed, request an extension rather than letting the file drop.
Final checklist before submission
Run through this list point by point before you click "send":
- Nothing has been ordered, signed or invoiced by the vendor.
- The quote is detailed, dated, in the exact name of the structure.
- Eligible lines are clearly separated from non-eligible ones.
- Administrative documents are all up to date (< 3 months).
- The vendor has confirmed they can provide FEDER mentions on the deliverable.
- Cash is planned to pay the vendor before reimbursement.
- A contact in your team is designated to answer the case officer's follow-ups.
A file ticking these seven boxes goes through almost systematically.
