A same-day decision may happen within the published range, but it is not a planning strategy. Use the seven-day recommendation as the practical minimum rather than the one-hour lower bound.
Portugal passport guide
This page is written around a Portugal 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 Portugal passport comes from Southern 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 Portugal traveller taking a regional West African itinerary with a possible second Benin entry. 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.
A Benin application works best when it is the last step in planning rather than the first. Once your passport and route are fixed, the online form becomes much easier to complete accurately.
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 Portugal, 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.
Dates and route
Check the first day you expect to enter Benin, not simply the day you leave home. Connections and overnight travel can make those dates different.
Entry type is a route question. One continuous stay normally points toward single entry; a planned exit and return points toward multiple entry.
After submission
Status tracking depends on the application number received after payment. Save it somewhere easier to retrieve than a temporary browser tab.
Once those details are stable, the application is largely administrative. Keep the process calm, keep the confirmation, and re-check the issued dates against the itinerary.
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.
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.
