Reorder points per SKU
Your products each get a trigger level from sales speed, lead time, and a safety buffer you control.
The Problem
Best Sellers Sell Out While the Reorder Waits in a Spreadsheet
It shows up once you carry more SKUs than one person can watch. Your stock levels live in the store, lead times live in someone's head, and purchase orders live in email.
01 · Stockouts
Your best seller sold out, and refills take 3 weeks.
Every SKU gets a reorder point from sales history and real supplier lead times.
02 · Stale sheets
The reorder spreadsheet showed 40 left because nobody updated it.
When stock drops to its reorder point, a draft PO appears automatically.
03 · Overstock
Hundreds of units of a slow color sit in your warehouse.
Reorders run on sales data and a safety buffer, not on gut feel.
04 · Untracked POs
Your POs go out as email attachments nobody tracks.
Each PO goes out the way that supplier accepts: email, API, or portal.
Your best-selling candle sold out on Saturday, and the supplier needs 3 weeks to refill it. The reorder spreadsheet said you had 40 left, but nobody updated it after the weekend sale. Meanwhile, 600 units of a slow color sit in your warehouse because someone reordered on gut feel. Purchase orders go out as email attachments that nobody tracks. Approvals happen in a hallway. Each stockout costs sales you won't get back, and each overorder ties up your cash.
We start with your sales history and real supplier lead times, then set a reorder point for every SKU. When stock drops to it, a draft PO appears, grouped by supplier and rounded to case packs. You approve it in one click from email or Slack, and it goes out the way that supplier prefers. Your reorders run on data, not on whoever remembers to check.
Reorder points for every SKU
Each of your products gets its own trigger from sales speed, lead time, and a safety buffer.
One-click PO approval
You approve or edit each draft PO from email or Slack before it reaches the supplier.
POs sent the supplier's way
Email with a PDF, a supplier API, or a portal upload, whichever each supplier accepts.
Our PO Automation Process
From Stock Review to Approved Supplier POs in Five Steps
You see the reorder points, the approval rules, and a test run on your real stock levels before anything reaches a supplier. Each step ends with something you approve.
We look at your SKUs, suppliers, lead times, and how you reorder today. You get a written plan with a fixed quote. If Shopify's own purchase orders and a low-stock alert already cover you, we'll tell you before we quote.
What's Included
What You Get With Purchase Order Process Automation
Every project covers reorder rules, draft POs, approvals, testing on your real stock levels, and handover. Larger plans add supplier APIs, ERP sync, and receiving checks.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built stores, integrations, and automation for.
We had a different kind of problem. People were visiting the store, adding products to their carts, and then disappearing before they finished the order. We had tried a few apps and made changes here and there, but nothing really seemed to solve the bigger issue. The team went through the shopping experience with us and pointed out things we hadn't really noticed ourselves. They cleaned up the cart and checkout flow, made the mobile experience much smoother, and helped us make the store feel easier to shop. I’m not going to pretend we fixed everything overnight, but it finally feels like the store is helping the sale instead of getting in the way of it.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Work Culture
Why Buyers and Ops Teams Trust Us With Their Purchasing
A bad reorder point repeats every cycle, as a stockout or as cash stuck on your shelves. These habits keep your purchase orders tied to real sales and real lead times.
Reorder points set per SKU
A candle and a gift set don't sell at the same speed or ship on the same lead time. Each SKU gets its own reorder point instead of one rule for the whole catalog.
Lead times measured, not guessed
We measure each supplier's real lead time from past POs and delivery dates. When a supplier slows down, your reorder points move with them.
One click to approve
Every draft PO waits for a person before it reaches a supplier. You approve, edit, or skip it from email or Slack in one click.
POs sent the supplier's way
Some suppliers want a PDF by email, and others take an API call or a portal upload. We send each PO in the format that supplier actually processes.
Tested on last quarter's stock
We run your reorder rules against last quarter's stock levels before launch. You see what the automation would have ordered next to what your team did.
Honest about simpler options
Shopify now includes purchase orders, and Shopify Flow can send low-stock alerts. If those cover your volume, we'll say so before we quote.

Good fit
Brands reordering from a spreadsheet
You check stock in a spreadsheet every Monday and email suppliers from it. Your best seller sold out over the weekend, again.
Shopify stores that relied on Stocky
Your team ran purchase orders through Stocky, and Shopify retired the app on August 31, 2026. You need a new home for reorders.
Brands with mixed supplier lead times
Your overseas supplier needs 45 days and your local one needs 5. One reorder rule for both keeps ordering too late or too early.
Finance leads who approve spend
You want every purchase order over a set amount approved before it goes out, without chasing sign-offs through email threads.
Agencies with inventory-heavy clients
Your client needs purchase order process automation wired into their store and ERP, and you want a partner who delivers it under your brand.
Not a fit
One supplier, rare reorders
You reorder from one supplier a few times a year. Shopify's own purchase orders and a Flow low-stock alert cost less than an $800 build, and our Shopify Flow Automation Setup page covers that alert.
Paying supplier bills
You need supplier bills matched and paid, not purchase orders created. Our Invoice Automation Software page covers bill capture and 3-way matching.
Full inventory system
You need a full inventory system with counts, transfers, and bundles. Our Shopify Inventory Management System page covers that bigger build.
ERP already creates POs
Your ERP already creates purchase orders, and you only need it connected to your store. Our Shopify ERP Integration page is the better fit.

Automating your purchase orders starts at $800 for reorder points on every SKU and draft POs for up to 3 suppliers. Up to 15 suppliers and 3 locations, with approval rules and ERP or accounting sync, costs $2,100. Supplier APIs, receiving checks, and lead-time tracking bring it to $4,400. You get a fixed quote after your free inventory review.
A first reorder workflow takes 1 to 2 weeks from the review to launch. Adding approval rules, more suppliers, and ERP or accounting sync takes 3 to 4 weeks. Supplier APIs with receiving checks take 5 to 6 weeks. Clean supplier and lead-time data speeds everything up, so we check yours during the free review.
Automatic PO generation watches each SKU's stock and drafts a purchase order when it falls to that SKU's reorder point. The draft groups every low item from the same supplier, rounds quantities to case packs and minimums, and waits for your approval. Stock already on order counts toward the level, so you don't reorder the same units twice.
We set each reorder point as average daily sales times supplier lead time, plus a safety buffer. The sales figure comes from your last 90 days, leaving out sold-out days so a stockout doesn't drag the average down. The buffer grows for products with uneven sales or unreliable suppliers. You can override any SKU, like a seasonal item before a holiday.
Yes, a PO reaches your supplier as soon as stock hits the level and someone clicks approve. We keep that one click on purpose, because a single wrong stock count can trigger a large order. Approvals arrive by email or Slack, so the wait is usually minutes, not days. If your approver is away, the draft goes to a backup after the time you set.
Yes, each of your suppliers can receive POs by email, API, or portal upload, whichever they accept. Email with a PDF works for almost every supplier and comes with every plan. API and portal delivery come with the Full Purchasing Workflow plan, because each supplier's system needs its own connection. If a supplier uses EDI, we connect through your EDI provider and quote that part separately.
Yes, approved POs can post to your ERP or accounting app, and received stock updates your store's inventory. We connect Odoo, Dynamics 365, QuickBooks Online, or Xero through their APIs. One catch: QuickBooks Online only includes purchase orders on its Plus and Advanced plans, per Intuit, so we check your plan during the review. Received quantities flow back to your store, so available stock stays accurate.
PO automation routes each draft to the right approver by amount or supplier, and flags anything unusual instead of sending it. Exceptions include a price above the last PO, a quantity far above normal, or a supplier with overdue deliveries. Flagged POs wait in Slack or email with the reason shown. After delivery, short or damaged receipts get flagged too, so your buyer can chase the supplier.
Yes, we can rebuild the reorder side of Stocky around your own rules, since Stocky is no longer available as of August 31, 2026. Shopify's migration guide covers built-in purchase orders for recording and receiving stock, and Flow for low-stock alerts. What's missing is deciding when and how much to order. We add reorder points and draft POs on top, and any Stocky history you exported can seed your lead times.
Every plan includes 30 to 90 days of support after launch, depending on your plan. In that window we tune reorder points that order too early or too late, fix failed sends, and adjust approval rules. After that, your buyer runs it with our runbook, or you can keep us on an optional support plan. You own the workflows, code, and accounts either way.
