Is Sumtracker enough for my multichannel stock?

What Sumtracker is

Sumtracker is a software subscription that keeps one stock count across your online shops and marketplaces. When a unit sells on Amazon, the count drops on Shopify, Etsy, eBay and Walmart too. That is called inventory sync. It also handles bundles (a kit made of several products), purchase orders (the order you send to a supplier) and reorder suggestions. If you want the wider picture of stock systems first, read my guide to an inventory management system.

It is built for small and mid-size brands. Its own site says it is trusted by more than 2,000 brands and rated 4.8 stars on Shopify. Those are the vendor's numbers, so treat them as a starting point and read the reviews yourself.

Plans and prices, as of November 2026

Sumtracker prices by the number of sales orders you get in a year, not by your revenue. There are two plans. Manage covers sync and day-to-day stock work. Replenish adds purchasing and forecasting.

Orders per year	Manage (monthly billing)	Manage (annual billing, per month)	Replenish (monthly billing)	Replenish (annual billing, per month)
2,500	$59	$50	$119	$100
10,000	$119	$100	$179	$150
25,000	$179	$150	$269	$226
50,000	$249	$209	$379	$318

Both plans allow up to 10 warehouses and 10 sales channels, and there is a 14-day free trial with no card needed. Above 100,000 orders a year you ask for a quote. The price list is on the Sumtracker pricing page, so check it before you buy.

The pricing page prices by order volume and lists no per-user charge, so check whether your team size changes the bill before you buy. That matters because some inventory tools charge per seat.

What it does well

• Stock sync across channels. It connects Shopify, Shopify Plus, Amazon, Etsy, eBay and Walmart. It picks up order edits, refunds, returns and cancellations automatically.
• Bundles. You can sell a gift box made of three items and have each part counted correctly.
• Duplicate listings. If the same product is listed twice, it can sync stock between the copies.
• Safety caps. You can set a maximum quantity per SKU on Etsy and eBay, and hide a product as out of stock at a level you choose.
• Everyday stock control. Stocktakes, cycle counts, barcode scanners, low-stock alerts, a stock valuation report and a public API come on both plans.
• Etsy listings and variants. Sumtracker's Etsy page says it handles active, inactive, sold-out and expired listings, matches variants by SKU, and lets you build bundles from any number of components, which suits print-on-demand and custom products.
• Shopify details. Its Shopify page says it works with Shopify, Shopify Plus and Shopify POS, links products with the same SKU across several stores, lets you transfer stock between locations, handles order edits, restocks and partial fulfilments, and does not sync Shopify customer information. Billing runs through Shopify.
• Safe to try. Installing it does not push anything to your shop. It only starts updating stock when you switch sync on.

Where it stops

• Amazon FBA is read-only. FBA means Fulfilled by Amazon, where Amazon stores and ships your stock. The pricing page lists FBA as "read inventory". Sumtracker sees your FBA stock but is not the thing that moves it. Check how it treats FBA stock against your own warehouse stock before you rely on it.
• It cannot create listings. It only updates stock. New products still start in Shopify, Amazon or Etsy.
• Purchasing is on the dearer plan. Purchase orders, stock transfers, forecasting, supplier price lists and the QuickBooks link are Replenish only.
• It is not a profit tool. It has a sales margin report on Replenish, built from the costs you store. Marketplace fees, shipping, ad spend and returns by channel are a different job. If you need that, see my guide to an ecommerce profit dashboard.
• No customer data from Amazon. Sumtracker says it does not sync or store Amazon customer information. That is good for privacy, but it means no customer view there.

How to set it up, step by step

This is the short version of a Sumtracker tutorial. Do it in this order.

1. Start the free trial and connect your main shop first, usually Shopify.
2. Connect your other channels one at a time. Products with the same SKU across stores link up on their own. A SKU is your product code, so make sure each product uses one code everywhere.
3. Clean up mismatches before you switch anything on. Look for missing SKUs, typos and two codes for one item.
4. Set up bundles and their parts.
5. Count your real stock and load it, by CSV file if you have many items.
6. Turn sync on for one channel, watch a day of orders, then turn it on for the rest.

Most failures I see are not the tool. They are bad SKUs. If sync is already misbehaving between two channels, my guide on how to sync inventory between Shopify and Amazon covers the usual causes.

A worked example with made-up numbers

Say you sell candles on Shopify, Amazon and Etsy. You get about 2,400 orders a year. On Manage you pay $59 a month, or $708 a year on monthly billing. That is about $0.29 per order.

Now say you grow to 9,000 orders a year and start ordering from three suppliers. You now want purchase orders and reorder suggestions, so you move to Replenish at the 10,000-order tier: $179 a month, or $2,148 a year. That is about $0.24 per order at 9,000 orders. The cost per order falls as you grow, but your bill jumps from $59 to $179 a month: $60 of that is the higher order tier and $60 is the move from Manage to Replenish.

These figures are illustrations, not quotes. Use your own order count on the pricing page.

How it compares to other options

Sumtracker sits in the middle. It is cheaper and simpler than heavy warehouse systems, and deeper than a plain sync app. For a wider look at the field, with prices, see my guide to multichannel inventory management software. If you only need Shopify and Amazon talking to each other, a lighter tool may do.

The trade-off is that you stay tied to a software subscription. Your pricing rises with orders, and you cannot change how it works. That is fine for most sellers. It becomes a problem when you have odd rules, such as made-to-order items, wholesale price tiers or a warehouse that works its own way.

What to add on top

For most growing sellers, Sumtracker handles stock and you add two more things:

• Supplier data. Lead times, minimum order quantities and price breaks. Replenish stores supplier price lists, but if your suppliers send stock files by email or portal, you still need a way to get those in. A small import routine or a shared sheet often does it.
• Profit reporting. Link stock cost to what each channel really pays you after fees. A ready-made profit tool such as Sellerboard, which tracks Amazon profit from your sales and costs, can do this for Amazon. For all channels in one view you usually need a spreadsheet or custom dashboard.

The QuickBooks link on Replenish helps with the books. For what the accounting side needs beyond that, read about ecommerce accounting reporting.

How I'd approach this

I would take the free trial with a copy of your real SKU list, not a demo store. Connect two channels, switch sync on for one product family, and watch it for a week. If overselling stops and the numbers match your shelf, it is doing its job.

Choose Manage if your problem is overselling. Choose Replenish only if you place supplier orders often enough that purchase orders and forecasts will save you hours. Do not pay for the dearer plan on the hope that you will use it later.

If you reach the point where you need stock, supplier files and profit in one screen built around how you work, that is the point to consider a custom layer rather than another subscription. Until then, a clean SKU list and a good sync tool carry you a long way.
