The best way to process customer purchase orders on Shopify depends on how buyers send them. Manual draft entry works at low volume. CSV import fits clean files. PDF and email-to-draft apps fit unstructured POs. Wholesale portals and EDI fit partners who will change process. There is no single “#1” app in this list. POinbox is the PDF and email path. Pick by how the buyer sends the order, not by a crown.
Option A: Manual Shopify draft orders
Use when you have a few short POs a day and staff already know the buyers.
Cost: every line is typed. Errors scale with length, not with good intentions. Steps: how to create a draft order. The time story: manual wholesale order entry.
Option B: CSV or Excel order import
Use when the buyer exports columns you can map, or you are loading history.
Cost: you become the person who reformats PDFs into a template. That is still manual. PDF and email vs CSV and POinbox vs Matrixify.
Option C: PDF and email to draft apps
Use when buyers email the PO they already produce and you want a draft plus a human on the exceptions.
Judge this category on formats, B2B company and location matching, catalog pricing, price-difference flags, and uncertain-line review. POinbox starts free (5 successful drafts); paid plans from $29/mo. It matches companies and locations, uses catalog pricing, and flags price differences and uncertain lines. LevelOps has a Built for Shopify badge and paid plans after a free allowance. Read POinbox vs LevelOps before you pick on a logo.
Option D: Wholesale portal or order form
Use when buyers will log in and order from your catalog. Adoption is the whole project. Many accounts will still email. Keep both. Portal vs emailed POs.
Option E: EDI
Use when a trading partner requires structured electronic orders and the volume pays for the setup. It is overkill for the long tail of PDF email. EDI vs emailed PDF purchase orders.
Decision table
| Buyer sends… | Prefer |
|---|---|
| A clean CSV on your template | CSV importer |
| A PDF or emailed PO in their layout | PDF/email → draft app |
| They will use your portal | Portal, plus email backup for the rest |
| An EDI-capable retail chain | An EDI project for that partner |
| A supplier PO so you can restock | Not this list. Inventory tools. |
A practical default for mid-market wholesale
Keep accepting the emailed PO. Put POinbox in front of the retype. Add CSV, a portal, or EDI only for the partners who already live that way. For the email majority, install it and run a week of real files. If named Plus price lists matter more than a Free-plan start, look at LevelOps. The category explainer is what “Shopify purchase order app” means. Automation boundaries: automate B2B order entry.
Score the buyer, not the app category
List the accounts that sent a PO last month. Next to each name, write how the order arrived: PDF, Excel in their layout, your CSV template, portal login, EDI, or a phone call. The tally is the decision. A store with forty PDF buyers and two EDI retailers does not “need an EDI strategy” as the first project. It needs the PDF path this month and EDI for the two who mandated it.
Score each path on four questions. Will the buyer change behavior? How many lines are in a typical PO? Who fixes a wrong SKU today? What happens to a price that disagrees with the catalog? Manual drafts answer all four with a person. CSV answers them if the file is already clean. A PDF app answers the first by not asking the buyer to change, and leaves the last two as flags. A portal answers the first only when they log in. EDI answers the first only when their IT agrees.
How to judge a PDF or email app without a trophy
Here is how POinbox handles the PDF and email path. It reads the formats buyers actually send. It matches companies and locations. It uses the catalog price and flags a difference. It holds uncertain lines before the draft is created. POinbox starts free (5 successful drafts); paid plans from $29/mo. LevelOps has the Built for Shopify badge and paid plans after a small free allowance. That is the reason you might still pay them.
Install POinbox on a copy of last week’s worst PDF. If the company is wrong and the flags are noisy, you learned something in an afternoon. If you need the Built for Shopify badge before you will trust a line, stay with LevelOps. POinbox vs LevelOps and LevelOps alternatives go further. Do not crown a winner on this page.
A stack you can explain to finance
Manual for phone orders and tiny reorders. CSV import for the partner who sends your template. POinbox for the PDF and email majority. A portal for buyers who completed onboarding. EDI for the retailer whose packet is on someone’s desk. Each tool has a named set of accounts. The failure mode is one slogan, “we’re moving everyone to the portal,” while the inbox still fills.
Write the account list down. Revisit it when a buyer changes. The process page is useless if it becomes a second inbox nobody owns. The cost of leaving the PDF group on manual entry is in manual wholesale order entry.
Mistakes that look like a process and aren’t
Buying an inventory purchase-order app because the search said purchase order. Asking every buyer to switch to CSV and then entering the PDFs anyway when they refuse. Launching a portal and telling ops to ignore the inbox. Starting EDI for the whole customer list because one retailer sent a packet. Each of those is a real project aimed at the wrong set of accounts.
The correction is the account list from the section above, with a tool named per group. Re-read it when someone proposes a single system. One system is available: Shopify drafts and orders. The intake in front of the draft can be more than one thing. POinbox is the intake for the file group, and it starts on Free (5 successful drafts).
Name an owner
A process with five options and no owner becomes the manual path again, because manual is the default when nobody is assigned. Name who watches the PDF inbox, who is allowed to accept a price exception, and who tells a buyer their portal login is optional. Review that once a month against the account list. The app does not hold the meeting. POinbox only shortens the file half of it.
