Document Automation
Personalize the order with automated packing slips, invoices, and inserts.
Don’t Let The Paperwork Slow Down Fulfillment.
Document automation helps you increase speed, eliminate errors, and personalize every order—automatically. Whether it’s pack slips, return forms, thermal inserts, or marketing collateral, our systems take the manual work off your team’s plate and keep your pack lines flowing. Engineered to integrate seamlessly with your warehouse operations, our solutions scale with your business, support multiple document formats, and deliver a more polished customer experience. By automating the documents, it’s one less item that needs to be picked.

Why Document Automation?
Better Unboxing, Happier Customers
Clean, complete, and personalized documentation elevates your brand and improves customer satisfaction from the moment a package is opened.
Improve Picking Speed (Fewer Lines Per Order)
If pickers and packers are currently dealing with the paperwork, by automating them, this means one less line per order. Speeding up your pickers dramatically.
Reduce Labor Dependence
Automation handles the time-consuming tasks of printing, folding, sorting, and inserting—helping you reallocate labor where it matters most.
More Accurate Orders
From thermal labels to full-color pack slips to promotional inserts, automate every document type in you pack line—accurately, consistently, and in real time.
On-Demand Customization
Insert branded materials, customer- specific messaging, and real-time shipping info—all pulled from your WMS or ERP and added to each order, with help from our WCS.
Scalable Across Pack Lines
Whether you run one line or ten, our document automation systems grow with you. Combine multiple systems to meet your volume, document mix, and layout needs.

Frequently Asked Questions
If you have any further questions, please reach out to us and we will be glad to help.
What kind of throughput can document automation systems handle?
Throughput varies by system, but ranges from up to 1,000 cartons/hour per FoldSerter line, 3,000 cartons/hour for CardSerter, and high-speed drop-in rates for ThermSerter in thermal insert workflows. Each is built to keep pace with high-volume operations, and the speed varies based upon the complexity of the process.
How do I know which system is right for my documents?
It depends on your document type and workflow:
– Use FoldSerter™ for multi-page pack slips or personalized inserts.
– Use ThermSerter™ to add a return label or small thermal packing slip.
– Use CardSerter™ for pre-printed postcards or marketing collateral.
Each system integrates to match your specific fulfillment flow.
Can we personalize documents for different customers or channels?
Yes. StreamTech’s WCS pulls data directly from your WMS or order database to insert personalized messaging, real-time shipping details, or branded materials for each order. This enables on-demand customization at scale.
What type of software interfaces work best for document automation?
StreamTech’s document automation systems integrate best using a shared directory or database connection where the software can identify and retrieve the correct document based upon the LPN or unique order ID from the package.
Absolutely. Whether you’re running a single line or a multi-line operation, our document automation can expand to meet your needs. You can combine systems like FoldSerter, ThermSerter, and CardSerter to support any document mix or volume. These document automation systems pair well with StreamTech’s end-of-line shipping automation technologies.
