ProFattura

ProFattura is an Italian invoicing and quoting platform for freelancers, sole proprietors and small businesses that need to issue electronic invoices under Italian rules. It takes the user from the first quote to the paid invoice in one continuous flow. Invoices are generated as FatturaPA XML v1.2 files and sent to SDI, the Italian Revenue Agency exchange system, through an accredited channel. Status updates (sent, delivered, accepted) arrive in real time, and invoices are kept in compliant storage for ten years. Prices can be entered gross or net, and the software handles the flat rate regime (forfettario) with no VAT, the legal wording and virtual stamp duty when due, as well as withholding tax and the ordinary VAT regime. Recurring invoices are the main strength of the product. A monthly fee, a quarterly retainer or the instalments of a signed quote are planned once, and on every due date ProFattura issues the invoice, sends it to SDI and emails a courtesy copy to the client, without anyone opening the app. Quotes can include attachments and are signed online by the client, on any device, with an advanced electronic signature (FEA) that records signer name, IP address, certified timestamp and the SHA 256 hash of the document. A signed quote converts into an invoice or a schedule of invoices without retyping. Supplier invoices can also be received in ProFattura once the platform recipient code is registered with the Revenue Agency, directly or through the accountant. Bank statements in PDF or CSV can be imported and matched to issued invoices, and an AI tax assistant analyses real revenue and cost data to suggest actions, without replacing the accountant. Teams can invite collaborators with admin, editor or viewer roles and manage several companies from one login. Accountants get a dedicated workspace for their VAT clients. Users coming from other software can import their XML invoice history, with free assisted migration. ProFattura runs in the browser on computer, tablet and phone. There is one plan with everything included: the first 12 months are free, no credit card required, then €29 per year, VAT included.

projectfacts

projectfacts ist eine All-in-One-Unternehmenssoftware aus Deutschland, die Projektmanagement, CRM & Vertrieb, Zeiterfassung, Ticketmanagement und Faktura in einer einzigen, DSGVO-konformen Plattform bündelt. Statt Insellösungen für jede Abteilung zu betreiben, steuern Teams ihre gesamte Auftragsabwicklung – vom ersten Lead bis zur bezahlten Rechnung – an einem Ort. Die Software richtet sich an mittelständische Dienstleister, Agenturen, IT-Unternehmen und Unternehmensberatungen, die projektbasiert arbeiten und abrechnen. Im Vertriebsmanagement bildet projectfacts den kompletten Sales-Prozess ab: Kontakte und Leads im integrierten CRM, Angebotserstellung mit Angebotsverfolgung sowie eine durchgängige Auftragsverwaltung. Aus gewonnenen Aufträgen entstehen direkt Projekte – inklusive Projektstrukturplan, Ressourcen- und Kapazitätsplanung sowie Projektmonitoring, das Budgets, Fortschritt und Wirtschaftlichkeit in Echtzeit sichtbar macht. Die integrierte Arbeitszeiterfassung erfasst Zeiten projekt- und tätigkeitsgenau – die Grundlage für belastbares Controlling und eine verlässliche Leistungsabrechnung. Erfasste Zeiten und Aufwände fließen automatisch in die Faktura: Rechnungen, Abschläge und wiederkehrende Positionen werden ohne Medienbruch erzeugt, und auch Eingangsrechnungen lassen sich strukturiert erfassen und Projekten zuordnen. Für Service und Support bietet projectfacts ein vollwertiges Ticketmanagement mit Ticketsystem, das Kundenanfragen kanalübergreifend bündelt und direkt mit Projekten und Kundenakten verknüpft. Ergänzt wird das Ganze durch Collaboration-Funktionen – gemeinsame Aufgaben, Dokumentenablage, Projektdokumentation und Teamkommunikation –, sodass alle Beteiligten auf demselben Informationsstand arbeiten. Weil alle Module auf einer gemeinsamen Datenbasis aufsetzen, werden Informationen nur einmal gepflegt und stehen bereichsübergreifend zur Verfügung – das reduziert doppelte Datenpflege, Schnittstellen-Aufwand und Reibungsverluste zwischen Vertrieb, Projekt, Support und Buchhaltung. projectfacts ist wahlweise als Cloud-Lösung oder On-Premises verfügbar, wird in Deutschland entwickelt und gehostet und legt besonderen Wert auf Datenschutz und Anpassbarkeit an individuelle Prozesse. Kurz: projectfacts ersetzt einen Flickenteppich aus Einzeltools durch eine zentrale Business-Plattform für Projekte, Vertrieb, Zeiten und Abrechnung.
