FAQ
Which platform should I choose?
Excel is best for one user working offline. Google Sheets is best when a small team shares the file online. A web app is best for several users, remote access or a growing business.
Can you adapt my existing invoice file?
Yes. Send me your current file or a sample invoice, and I will automate it, keep your layout and add the features you need.
Can invoices be sent automatically by email?
Yes. In Excel through Outlook, in Google Sheets through Gmail, and in a web app through your own email service, with the PDF invoice attached.
