Absolutely love FastBill!

Oh my goodness, FastBill is just fantastic! I signed up for the Pro plan and it's been a game changer for my business. The Zeiterfassung and Projektmanagement tools are brilliant, I can keep track of everything so easily. I even used the Scan-App for my Beleg-Erfassung, and it worked perfectly. My Steuerberater-Schnittstelle makes tax season so much less stressful. I'm telling all my freelancer friends about it. Will absolutely be renewing next year!

Good value for Solo plan

I was looking for an invoicing solution that wouldn't break the bank. FastBill Solo caught my eye with its pricing. I took advantage of the annual billing discount and saved a good chunk. The 30-day free trial helped me confirm it was the right fit. Felt like a smart purchase overall.

Worked out well

So, I needed something to handle my invoicing and tried FastBill out. I signed up for the FastBill Premium. It was pretty easy to get started with, just uploaded my info and everything. The automated Buchhaltung feature is super handy, saved me a bunch of time. I liked how it integrated with my bank too. Felt pretty good about it, definitely made my life a bit simpler with the finances.

Decent software, minor hiccup

I started using FastBill for my small business, mainly for Rechnungen schreiben and the Finanzübersicht. The onboarding was smooth, and the interface is quite intuitive. I opted for the annual subscription, which gave a good discount, making it a fair price for what it offers. The Banking Integration worked well most of the time, though one time it took a little longer to sync my transactions, maybe a temporary server thing. Customer service was helpful when I had a question about the DATEV Export. Overall, it's a solid tool, but consistent real-time bank sync would make it perfect.

Thinking of switching to FastBill from Lexoffice. Is the data transfer complicated or can I just port everything over easily?

T Troy K. 2 months ago
Yeah, I moved from Lexoffice a while back, it was pretty smooth. They have an import feature for it.

I think they have a direct import tool for Lexoffice. I remember seeing that in their FAQ or on their site when I was checking it out. Shouldn't be too much of a headache.
