Questions Fréquentes

Découvrez les réponses aux questions les plus courantes sur notre logiciel de facturation.

Généralités sur les logiciels de facturation

C'est quoi un logiciel de facturation, un programme de devis et factures, un outil de gestion commerciale, une solution pour faire ses factures ?

Un logiciel de facturation est votre assistant digital pour gérer toute la partie administrative de votre entreprise.

Avec Flexina, vous gérez en un seul endroit :

  • Documents commerciaux : Devis, factures, bons de commande, bons de livraison
  • Cycle de vente complet : Du premier contact client jusqu'à l'encaissement
  • Gestion des achats : Commandes fournisseurs, réception, factures d'achat
  • Suivi des stocks : Entrées, sorties, inventaire en temps réel
  • Signature électronique : Validation instantanée de vos devis

C'est bien plus qu'un simple générateur de factures : c'est le cerveau de votre activité commerciale !

Quelles sont les principales fonctionnalités offertes par un logiciel de facturation pour aider à la gestion d'entreprise ?

Un logiciel de facturation moderne, c'est votre partenaire business au quotidien. Flexina transforme la gestion administrative en atout pour votre croissance :

  • Du devis à l'encaissement en 3 clics : Créez un devis, faites-le signer en ligne, transformez-le en facture et encaissez. Plus de paperasse, plus d'erreurs, juste de l'efficacité.
  • Votre entreprise dans votre poche : Factures, stocks, planning, achats... Tout est synchronisé et accessible partout. Pilotez votre activité depuis votre canapé ou en rendez-vous client.
  • Un assistant qui ne dort jamais : Relances automatiques, alertes stocks, rappels d'échéances... Flexina travaille pour vous 24h/24. Vous ne ratez plus aucune opportunité.
  • Vos chiffres parlent enfin : Tableaux de bord visuels, évolution des ventes, rentabilité par client... Prenez les bonnes décisions sans être comptable.

Résultat ? Vous passez moins de temps sur l'administratif et plus de temps à faire ce que vous aimez : développer votre business et satisfaire vos clients.

Tarification et versions gratuites

Est-il possible d'obtenir une version gratuite d'un logiciel de facturation et quelles sont ses limites ?

Méfiez-vous des solutions de facturation soi-disant gratuites ! En réalité, elles cachent souvent des limitations importantes qui peuvent freiner votre activité : fonctionnalités bloquées, nombre de factures limitées, ou pire, une dépendance à un système qui risque de vous faire perdre du temps et de l'argent.

Chez Flexina, nous avons fait un choix différent : proposer un tarif juste et transparent, inchangé depuis 15 ans. Pour un investissement raisonnable, vous bénéficiez :

  • D'une solution complète sans restriction de fonctionnalités
  • D'un accompagnement personnalisé pour votre réussite
  • De mises à jour régulières sans surcoût

Avec le meilleur rapport qualité-prix du marché, Flexina est un investissement rentable qui accompagne durablement la croissance de votre entreprise. Pourquoi risquer l'avenir de votre société avec une solution gratuite quand vous pouvez avoir un outil professionnel pour quelques euros par mois ?

Une question particulière ?
