Business and productivity guides: invoices, resumes, QR codes
Freelancers, small shops and job seekers need the same handful of documents over and over: an invoice that gets paid, a resume that parses cleanly, a professional email signature, a QR code for a flyer or menu, and a plan for social posts.
The invoice, resume, signature and QR tools run in your browser and need no account; invoice drafts are saved on your own device. The AI email reply tool sends the email text you paste to an AI service, and the social media scheduler stores posts on your device unless you connect an account to publish.

Do the invoice and resume builders add a watermark?
No. Both export clean PDFs with no GrabCast branding and no account. Drafts are kept in your browser so you can come back to them on the same device.
Do GrabCast QR codes expire?
No. The QR Code Generator makes static codes: the link or text is encoded directly in the pattern, with no redirect service in between, so the code keeps working as long as the destination does.
What should every invoice include?
At minimum your details, the client's details, a unique invoice number, issue and due dates, itemized lines, totals with any tax, and how to pay. VAT-registered businesses in the UK and EU have extra requirements; check local rules.
Will an ATS read a two-column resume?
Often badly. Many applicant tracking systems read left to right across columns, which scrambles job titles and dates. A single-column layout with standard headings is the safest choice.
Is the social media scheduler free?
Yes, with no credit card. Without a connected account, drafts and planned times stay on your device and you get reminders; connecting an account lets supported platforms publish for you.
