Automated Order Confirmations & Receipts
Every order needs a confirmation. Every return needs a receipt. E-commerce teams use Mergram to generate these at scale from order data exports, ensuring every customer receives a professional, branded PDF document without the manual overhead.
The Challenge
Online stores process dozens to thousands of orders daily. Each order triggers a need for documentation — confirmations for customers, packing slips for warehouses, receipts for accounting, and return labels for post-purchase support. Manually generating these documents is impossible at scale, and the default emails sent by platforms like Shopify or WooCommerce often lack the branding, detail, and professionalism that customers expect.
The problem compounds during peak seasons. Black Friday, holiday sales, and flash promotions can generate 10 to 50 times the normal order volume. Store teams find themselves choosing between sending generic, unbranded confirmations or spending hours manually creating personalized PDFs. Neither option is sustainable.
Additionally, many e-commerce operations need documents beyond what their platform provides natively. Wholesale orders may require detailed line-item PDFs with custom pricing. International orders need documents with localized formatting. Subscription businesses want to generate professional renewal invoices that match their brand identity.
The Solution
Mergram bridges the gap between your order data and professional document output. Instead of relying on generic platform emails, you design beautiful PDF templates and merge them with your actual order data — product names, quantities, prices, shipping addresses, tracking numbers, and even product images.
The result is a fully automated pipeline: orders come in, data flows into a spreadsheet or via API, and personalized PDFs are generated and delivered without manual intervention.
Tip
Use the REST API to trigger merges automatically whenever a new order is placed. Combined with Zapier or Make.com, you can build a fully hands-off document generation pipeline.
Document Types
| Document | Key Merge Fields | Typical Use |
|---|---|---|
| Order confirmations | Order ID, items, prices, estimated delivery | Post-purchase email |
| Receipts | Transaction ID, payment method, totals | Payment confirmation |
| Packing slips | SKU, item name, quantity, warehouse location | Fulfillment center |
| Return labels | Order ID, return reason, QR code | Customer support |
| Gift receipts | Recipient name, item names (no pricing) | Gift orders |
| Wholesale invoices | Line items, bulk pricing, PO number, terms | B2B orders |
Step-by-Step Workflow
- Export your order data from your e-commerce platform. Shopify, WooCommerce, BigCommerce, and most platforms support CSV or Excel exports. You can also use the REST API for real-time automation.
- Design your PDF template — upload a branded order confirmation, receipt, or packing slip. Use Canva, Adobe Illustrator, or any design tool that exports to PDF.
- Map order fields onto the canvas using the visual editor. Place the order ID, customer name, item details, total amount, and shipping address exactly where they should appear.
- Add barcodes or QR codes — drag a barcode field onto the canvas and map it to your Order ID column. Each generated PDF will include a scannable barcode for warehouse scanning or return processing.
- Generate personalized PDFs for each order row in your spreadsheet.
- Email or download — send documents directly to customers, or download as a ZIP for batch printing at your fulfillment center.
Tip
Upload product photos to Media Albums and map them by SKU or product name. Mergram will automatically embed the correct product image on each order PDF, giving customers a visual confirmation of what they purchased.
Integration Options
Mergram integrates with your existing e-commerce stack through multiple pathways:
- REST API: Programmatically trigger merges from your order pipeline. Send a POST request with your template ID and order data, and receive generated PDFs in response. Ideal for custom integrations and headless commerce setups.
- Zapier: Build no-code workflows that connect Shopify, WooCommerce, or any platform to Mergram. Trigger: new order created. Action: generate PDF and email to customer.
- Make.com: Create multi-step scenarios that enrich order data before generating documents — for example, pulling tracking numbers from ShipStation before creating the shipment confirmation PDF.
