Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureYour customers email purchase orders as PDFs, spreadsheets and CSVs. You retype them. PO Engine reads the order, matches every line to your products, and creates a Shopify draft order priced from your own catalogue and B2B price lists. Anything it is unsure about it asks you once, then remembers how that customer words things forever. It writes a draft order and stops.
Retyping wholesale purchase orders is slow and error-prone. Pomelo reads the PO your buyer sends, whether a PDF, scan, Excel file, CSV or pasted email, and matches every line to your products by SKU, barcode or description. You check the lines beside the original and create a draft order with the buyer's PO number, prices, payment terms, shipping charge, addresses and customer or B2B company attached.
- Reads purchase orders as PDF, Excel or CSV. No template for your buyers.
- Matches lines to your products, and asks you rather than guessing when unsure.
- Learns how each customer words things, so the same order never asks twice.
- Prices from your own catalogue and B2B price lists, never from the buyer's PDF.
- Reads PDFs, scans, Excel, CSV and email text, including case-pack quantities
- Matches lines by SKU, barcode or description and flags anything to check
- Carries the PO's payment terms, shipping charge and discount onto the draft
- Attaches the buyer as a customer or B2B company location on the draft order
