Common workflows
When the job takes more than one tool, follow the steps in order.
Prepare a PDF for email You have several documents, some of them phone scans, and the recipient wants one PDF attached to an email. Sending them separately gets messy, and the combined scan is far too large to attach. Prepare documents for an online application Your certificates are phone photos, your passport photo is a 4 MB image, and the portal rejects each upload for a different reason: wrong format, too large, or too many files. Create and send a business invoice You agreed a price, applied a discount, and now need to know whether VAT goes on before or after it, then produce a document a corporate client's accounts team will accept. Calculate Nigerian salary deductions You have an offer of a gross monthly figure and need to know what lands in your account, and whether it supports the annual rent a landlord will ask for up front.
