Why teams use Docuplate

Templates your team can edit
Non-developers adjust layouts in the browser; engineers call the same template ID from production code.
Standard REST endpoints
Generate PDFs with a POST request and JSON body mapped to your template fields, as documented in the integration guides.
Webhooks without API keys
Need simpler automation? Webhooks and public forms work on every plan without server-side API integration.
Built for volume
Pro and Business plans raise monthly PDF limits, team seats, and AI audit quotas for production workloads.

How it works

Step 1
Design and publish a template
Create the document layout in the builder, map JSON field paths, and note the template ID from the URL.
Step 2
Create an API key
Generate a key on Pro or Business and store it securely in your backend environment.
Step 3
Call the generate endpoint
POST customer and line-item JSON; receive a PDF binary or download URL in the API response.

Common questions

Which plans include API keys?

REST API keys are available on Pro ($39/mo) and Business ($129/mo). Webhooks work on the free plan.

What format does the API expect?

JSON payloads matching your template field paths. The guides include curl, Node.js, and Python examples.

Can I preview before going live?

Yes. Use sample data in the builder to preview PDFs, then send the same JSON shape from your application.

How Docuplate helps you ship professional business PDFs

Most small businesses send the same documents every week, invoices after a job, quotes before work starts, and delivery notes when goods ship. Generic word processors make it easy to break alignment, miss totals, or reuse outdated layouts. Docuplate is built for that repeat workflow: design once, fill in structured data, and download a print-ready PDF that looks the same every time. Templates for invoices, quotes, and delivery notes are included when you create a free account, and you can upload an existing PDF to turn it into an editable starting point.

Every template field can bind to customer names, invoice numbers, tables of line items, and totals. Automatic checks flag blank required fields and mismatched totals before download. When you outgrow one-off downloads, connect a webhook or public form, or use the REST API described in our integration guides when your engineering team is ready.

Plans scale from a free tier through paid options with higher monthly PDF limits, team seats, and custom branding. Compare limits on our pricing page before you commit. Generated files are standard PDFs compatible with common viewers; for background on the format, see the ISO PDF specification. If you invoice Australian customers, official invoicing guidance from business.gov.au summarises what to include on tax invoices.

Built for people who send documents, not write code

Small business owners, office teams, and developers who need API automation all use the same visual editor. Starter templates cover invoices, quotes, and delivery notes out of the box.

Frequently asked questions

Do I need to know how to code?

No. You can create, edit, and download PDFs entirely in your browser. Coding is only needed if you want to automate PDFs from another system.

Can I upload a PDF I already send to customers?

Yes. Upload your invoice or quote PDF and Docuplate turns it into an editable template. Complex layouts get an AI-assisted import on Pro and Business plans.

What can the AI features do?

Run an AI layout audit, apply fix-layout suggestions, and map JSON fields. Starter includes 25 AI audits per month; Pro and Business add higher limits and AI-assisted PDF import. Free includes 3 AI fix-layout runs per month.

What templates do I get when I sign up?

17 starters across construction, retail, professional services, healthcare, and hospitality, including invoices, quotes, work orders, visit summaries, and more.

How is this different from Word or Google Docs?

Docuplate is built for business documents you send repeatedly. Layouts stay consistent, totals stay aligned, and you can reuse the same template every month.

What does the free plan include?

17 starter templates, local PDF import, webhooks, forms, 3 AI fix-layout runs, and 50 PDF downloads per month. CSV batch and AI audits start on Starter ($19/mo). Pro ($39/mo) adds API keys and teams; Business is $129/mo. See the pricing page for details.

Can I generate PDFs in bulk from a spreadsheet?

Yes. Upload a CSV on Starter and above to batch-generate dozens of PDFs from one template.

Is there a PDF generation API?

Pro and Business plans include REST API keys. Webhooks and public forms work on every plan without API keys.

How do I automate PDF generation without coding?

Connect a webhook URL to your store or workflow tool, or share a public form link.

What business documents can I create?

Invoices, quotes, estimates, receipts, delivery notes, purchase orders, work orders, certificates, and status reports.
