A well-timed application sits between two boundaries: no more than 90 days before entry and preferably at least seven days before it. That is the useful window for most planning.
Austria passport guide
This page is written around a Austria passport and the decisions that affect a real Benin trip: exemption status, the travel document, first entry date and whether the route needs re-entry.

Nationality check
Benin's official eVisa FAQ says foreign nationals can submit an eVisa application online and separately gives African nationals a general 90-day visa-free rule. A Austria passport comes from Central Europe, so do not assume that African-national rule covers this trip.
Before purchasing an eVisa, confirm whether your exact passport has any separate exemption. If a visa is required, use the published eVisa choices as the starting point rather than relying on a generic travel-site label.
Imagine a Austria traveller taking a business meetings followed by a direct return home. The visa decision should follow that route. If there is only one arrival, repeated-entry permission may add no value; if Benin appears twice in the itinerary, the entry question changes immediately.
The easiest way to avoid a poor visa choice is to describe the trip in plain terms first: when you arrive, how long you stay, and whether you will cross out of Benin and come back.
Dates and route
If the itinerary changes before submission, update the travel date before paying. After issue, Benin says the automated eVisa cannot normally be edited.
Choose entry type from the sequence of countries on the booking, not from habit. The right answer is determined by how many times you expect to cross into Benin.
Travel document
Use the same passport for the application and the journey. Copy the number directly from the document rather than from an old booking profile, and check the expiry date character by character.
For travellers departing from Austria, it is also worth checking that airline bookings use a name format that can be reconciled with the passport. Minor formatting differences are common, but the visa form itself should follow the travel document.

Card payment
Do not let a payment problem tempt you to retype passport data quickly. Keep the verified form information stable and deal with the card or bank verification separately.
Published visa choices
The figures above are the government fees published for self-service online applications. They do not include separate assistance or banking charges.
After submission
The useful record after submission is the application number in the confirmation email. That is what the platform asks for when you want to follow the request.
For this trip, accuracy is more valuable than speed. A form submitted ten minutes later with the right passport and dates is better than a fast application that cannot be edited after issue.
Start with the passport nationality and any applicable exemption. If a visa is required, then compare the published eVisa duration and entry options against the itinerary.
Benin states that eVisa validity begins on the intended date of entry entered in the travel-data section.
The published self-service fees are €50 for 30-day single entry, €75 for 30-day multiple entry and €100 for 90-day multiple entry.
Keep the application number sent by email after confirmed payment because it is used for status tracking.
Check the passport, the first Benin arrival date and every planned re-entry. If those three facts are settled, the visa choice is much easier to judge.
