Preparing a document before it goes out to a customer is rarely a one click job. An invoice might need a password before it's safe to send, a set of scanned pages might need pulling out of a longer file, or a receipt might need a watermark to prove it came from the business. Doing that by hand for every order or invoice adds up to a lot of small, repetitive admin.

PDF Blocks handles that busywork as a step inside a Zap, extracting pages, adding a password, merging documents, or applying a watermark automatically before the file moves on, with nobody needing to open it by hand. Paired with Mobile Message through Zapier, an order in Shopify or an overdue invoice in Xero can set that document work in motion, and once it's done Mobile Message can text the customer to say a protected, merged or watermarked copy is ready for them.
