The Unlayer document builder mid-edit on a SaaS proposal: a centered canvas shows a proposal cover page with the client name 'Acme Co' merged into the headline, a scope-of-work table with line items, a pricing summary block, and a signature footer; the right rail lists draggable blocks (Heading, Text, Image, Table, Pricing, Signature, Page break, Footer) and an 'Insert merge field' prompt sits at the bottom right.

Common challenges

The build cost of a document automation platform.

Building the editor, the renderer, the merge engine, and the white-label theming yourself is an 18-month roadmap. Most platforms underestimate it on day one.

Without Unlayer

  • Customers fight your rigid templates and demand a richer editor every quarter.

  • Engineering owns a homegrown PDF pipeline that breaks every time the data model changes.

  • Merge-field UX is fragile and customers paste data into the wrong placeholders.

  • Volume spikes melt your renderer the moment a large customer onboards.

  • White-label depth stops at the logo swap and enterprise deals stall on it.

  • Every new document type re-implements the same designer from scratch.

With Unlayer

  • Customers design proposals, contracts, and statements with drag-and-drop simplicity.

  • A managed Documents API renders thousands of personalized PDFs a day, no homegrown pipeline.

  • Merge fields, live preview, and validation are first-class so the right data lands in the right slot.

  • Volume scales horizontally so the largest customer feels the same as the smallest.

  • Fully white-label theming so every customer sees their own brand, end to end.

  • A ready-to-embed Document Builder ships in days, not years.

Documents API

Personalized PDFs, generated at scale.

Proposals, contracts, invoices, statements, receipts. Design once in Unlayer, render per-recipient with merged data, at any volume your platform demands.

  • Designed once, rendered infinitely

    Build the template once in the Unlayer editor; render millions of personalized variations server-side, per customer, contract, or transaction.

  • Merge any field

    Customer name, line items, balances, terms, jurisdictions, custom JSON. Pass data in, get a branded PDF back.

  • Trigger from any event

    Quote accepted, contract signed, statement closed, charge captured. Webhook in, PDF out, no human in the loop.

  • Scales to any volume

    A managed renderer that scales horizontally per tenant. The largest customer feels the same as the smallest.

AI Assistant

AI that drafts the full document.

Your customers describe the proposal, contract, or statement they need. Unlayer ships a polished first draft. Fully designed, on brand, ready for review in seconds.

  • Drafts full documents, not just paragraphs

    Complete proposals, contracts, and statements with every section in place from one brief.

  • Reworks for every audience

    One proposal restyled for enterprise vs. SMB, US vs. EU terms, or any segment.

  • Stays on brand and on template

    Outputs match each tenant’s brand kit and approved templates. Deal-ready, not generic.

The Unlayer AI assistant panel mid-conversation: a sales rep asks for a SaaS proposal cover and the assistant returns a complete proposal page with a hero block, scope-of-work table, pricing summary, terms, and sign-off on brand from the first draft.
