How it actually works
The voucher never reaches your bank account. You apply, it is granted as a credit assigned to your company, and then you choose a registered digitalisation agent. The agent does the work and bills against the voucher. You sign an agreement with them and evidence that the solution is running.
That sequence matters because it reverses the order many people use. Commissioning the website first and applying afterwards does not work: anything contracted before the grant is usually not eligible. If you intend to use it, the voucher comes first.
The three traps
The first is the service period. The voucher does not pay for a website and leave: it obliges you to keep it operational for the months the call specifies. If the supplier disappears after three, the problem is yours.
The second is confusing the maximum amount with what you will get. The maximum is per category and per size band, and a website category does not cover the same ground as an e-commerce one.
The third, and the most expensive, is letting the voucher pick your supplier. There are agents whose entire model is to build the minimum that can be evidenced and charge the maximum. The voucher covers a cost; it does not guarantee that what gets built is any use once the service period ends.
What to do before applying
Check first whether you meet the current call’s requirements and whether funds remain, because both change. Then decide which category fits what you genuinely need, rather than the one that pays most.
And before signing with an agent, ask them exactly what you would ask without a voucher: which pages, who writes the copy, what happens to the domain, what you pay monthly, and what you take with you if you leave. A public grant is no reason to lower the bar on the questions.
