Automate Emailed POs into BigCommerce

Your customers email you purchase orders. Here is how AI reads the PDF, applies your BigCommerce customer-group pricing, and creates a finished order in the store you already run.

Updated October 2026

To automate emailed purchase orders into BigCommerce, forward the PO to software that reads the PDF or email, identifies the customer, matches each line to your catalog, applies that customer's BigCommerce customer-group pricing, and creates the finished order in your store. With Dynition, forwarding the email is the only manual step, and anything the system is unsure about is flagged for a rep before the order is created.

Why does your BigCommerce store still get emailed PDFs?

BigCommerce runs your storefront and your B2B catalog beautifully. But a large share of wholesale orders never touch the storefront: they arrive as a PDF attached to an email, or as an order typed into the message body. A rep opens each one, finds the customer, reads every line, translates the customer's part numbers to your SKUs, looks up that customer's pricing, and keys the order into BigCommerce by hand.

That is slow, and it is where errors get in: a mis-keyed quantity, a wrong SKU, or a generic price applied to a customer who has a negotiated rate. The store is modern; the order intake is still manual.

How does AI read the emailed order?

Modern extraction reads the PO the way a rep would, in seconds: it pulls every line item, quantity, unit, and customer part number off the PDF or email, including scanned and inconsistent formats. But reading the document is the easy part. The work that makes an order correct comes next.

How does Dynition fit into BigCommerce?

Dynition connects to BigCommerce with a store-level API account, reads your catalog, customers, and pricing, and writes finished orders back. Once it has read the PO, it:

  • Identifies the customer and translates their part numbers and shorthand to your BigCommerce SKUs.
  • Applies your customer-group pricing so each line is priced the way that specific customer should be charged, not at generic list price.
  • Validates the details, checking pricing, address, and payment terms against what your store holds.
  • Creates the finished order in BigCommerce, ready to fulfill, or flags anything uncertain for a rep to confirm first.

The connection itself takes minutes: you create a store-level API account in BigCommerce, give it access to read your products, customers, and settings and to create orders, and paste the credentials into Dynition. There is no app to install on your storefront, and your customers never see a change.

What does it look like in practice?

At First Place Supply, a janitorial and sanitation distributor:

  • 95% of POs processed zero-touch, no rep involvement
  • Order entry went from 15 minutes to 20 seconds
  • Each rep got about 6 hours a week back
  • Order error rate fell below 0.5%, from roughly 3% manual
  • 100% of pricing, address, and payment-term errors were caught before an order went out

Defaults are what First Place Supply measured before automating: 15 minutes per PO and a ~3% error rate. Dynition pricing uses the published rate: your first 15 POs free, then $2 per PO, dropping lower at volume. We show the $2 rate here, so your real bill at volume only comes in below this. Error cost sits on the manual side because Dynition catches pricing, address, and term errors before the order is created. Every input is your own estimate, and the math is just arithmetic on it. See it run on your own POs.

Emailed POs into BigCommerce, answered

How does Dynition connect to my BigCommerce store?

You create a store-level API account in your BigCommerce control panel (Settings, then Store-level API accounts), grant it access to read your Products, Customers, and settings and to create Orders, and paste the Access Token, Client ID, and Client Secret into Dynition. Credentials are stored encrypted. Setup takes minutes, and there is no app to install on your storefront.

Does it apply my customer-specific pricing?

Yes. Dynition identifies which customer sent the PO and applies that customer's BigCommerce customer-group pricing to every line, so the order is priced the way that customer should be charged, not at generic list price. If a PO price does not match, the line is flagged for a rep before the order is created.

Does it create a real order or just export data?

It creates a real, finished order in BigCommerce, ready to fulfill. Dynition matches each PO line to your catalog, applies the pricing, checks the details, and writes the order into your store. You are not left with a spreadsheet or a data dump to key in yourself.

What happens when a line does not match a product?

The order is held and the line is flagged for a rep, who picks the right SKU or rejects the line before anything is created in BigCommerce. Dynition is built to stop rather than guess, so an unmatched line never becomes a wrong product in a live order.

Do my customers have to change how they send orders?

No. Your customers keep emailing purchase orders exactly as they do today, as PDFs, spreadsheets, or plain email text. You forward the email to Dynition, it reads the order, applies your BigCommerce pricing, and creates the order. The buyer does not change behavior; you stop rekeying.

How accurate is it?

At First Place Supply, the order error rate came in under 0.5%, down from roughly 3% with manual entry, and 100% of pricing, address, and payment-term errors were caught before an order went out. 95% of purchase orders completed with zero rep touch. Accuracy holds because anything uncertain is flagged for review instead of guessed.

What does it cost?

Dynition publishes its pricing, unlike most vendors in this category. Your first 15 purchase orders are free, then $2 per PO, dropping to $1 at volume, with no setup fee and no per-seat charge. You pay for finished orders, not per page scanned or per user. Estimate your own savings with the calculator on this page, or see the full pricing at dynition.ai/pricing.

What if I also run Shopify or another platform?

Dynition creates finished orders in both BigCommerce and Shopify, including Shopify B2B. If you run a different platform or an ERP-first workflow, bring it to a demo and we will be straight about whether we are the right fit yet.
