SKU IQ does one thing: it keeps a point-of-sale system and an online store on the same stock count. Square, Clover or Lightspeed on the counter; Shopify, WooCommerce, BigCommerce, Wix or Squarespace on the web; one pairing per account. For a shop that sells the same shelf in both places, that’s the whole problem.
The alternatives search usually starts with one of three things: the bill for attribute or image sync on top of quantity sync, a disconnect that needed staff to reconnect, or a second sales channel SKU IQ doesn’t reach, such as Etsy, eBay, Amazon or QuickBooks. This guide compares seven options on how they connect a till, how stock moves, what sets the bill, and what each can’t do. QuickSync is one of them.
What SKU IQ does, and where it stops
SKU IQ links one POS to one e-commerce store and syncs quantity on the Basic plan, attributes and new-item auto-push on Plus, and images plus a priority sync lane on Pro. Multi-location is supported through Square, Lightspeed and Shopify locations at $10 a location. It doesn’t list on marketplaces, it doesn’t route orders, and it doesn’t post to accounting. Shopify App Store reviews sit at 4.1 stars across 120, with 16% at one star; the themes are recurring disconnects, quantity discrepancies and slow fixes.
SKU IQ pricing in 2026
| Plan | Monthly | What you get |
|---|---|---|
| Basic | $19 | Quantity sync only |
| Plus | $49 | Adds attribute sync and automatic push of new items |
| Pro | $99 | Adds image sync and accelerated, priority sync |
| Add-ons | $15 each; $10 per location; $99 dedicated lane | Attribute sync, auto push, image sync, multi-location, dedicated sync lane |
Why merchants look for alternatives
- Feature-gated sync. Quantity is $19; getting descriptions and images across is $49 to $99 or $15 an add-on. The till and the website agree on the number but not on the product.
- One pairing. One POS to one store. A second web store, an Etsy shop or an eBay listing is outside the model.
- Disconnects. The most repeated review theme is the link dropping and staff having to reconnect it, with quantity mismatches in between.
- No marketplaces, no books. Amazon, eBay, Etsy, Walmart and QuickBooks aren’t connected.

The 7 best SKU IQ alternatives
1. QuickSync: the till plus up to seven more shops
QuickSync connects Square, Clover and Lightspeed to the places you sell online and keeps one count across up to eight shops. All three tills push to it: the moment something scans, the new quantity is written to Shopify, WooCommerce, Squarespace, Etsy, eBay, Amazon and TikTok Shop in under a second, and QuickBooks gets the figure for the books. Product details, prices with a per-channel rule, photos and options move too, on every plan; there’s no attribute or image tier.
Plans are by variation count: $19 a month for 1,000 items and two shops, $29 for 2,500, $69 for 10,000, $99 for 20,000, with each shop after the second adding the plan price. A till and a website is the $19 case.
Where it doesn’t fit: none of the three tills accept a tracking number back: Square and Clover have no field for it, and Lightspeed marks the sale shipped without the number. Eight shops is a hard cap. Etsy, eBay and Squarespace stock are read every two minutes rather than pushed. QuickSync and SKU IQ side by side.
2. Thrive by Shopventory: the back office around the till
Thrive (the renamed Shopventory) pairs Square, Clover and Shopify POS with Shopify, Square Online, WooCommerce and BigCommerce and adds purchase orders, transfers, vendor management, bundles and recipes, forecasting and QuickBooks Online sync. Starter is $59 a month ($55 annual) for one user, one location-integration and 1,500 transactions; Standard $129, Professional $279, Elite $559. 4.6 stars on 105 Shopify reviews.
Where it doesn’t fit: no marketplaces at all, and the tiers jump. Source: thrivemetrics.com/pricing. QuickSync and Thrive side by side.
3. Trunk: Square plus marketplaces, metered on orders
Trunk connects Square to Shopify, Squarespace, Wix, WooCommerce, Etsy, eBay, Amazon, Faire, TikTok and QuickBooks Online and syncs in real time on order events, with bundles on its Pro plan. Essential starts at $35 a month for up to 100 orders and steps to $279 at 10,000. 4.9 stars on 391 Shopify reviews.
Where it doesn’t fit: no Clover, no Lightspeed, no listing creation, and the bill moves with each order band. Source: help.trunkinventory.com pricing article.
4. Nembol: Square plus marketplaces and social
Nembol connects Square to Shopify, WooCommerce, Squarespace, Wix and the marketplaces, with listing tools and stock pushes its help centre puts at a split second to a minute. $39 a month for 500 products, $49 for 2,000, $79 for 5,000, $129 for 15,000.
Where it doesn’t fit: no Clover or Lightspeed, no QuickBooks, European support hours. 4.2 stars on 54 Shopify reviews. Source: nembol.com/pricing.
5. Shopify POS: drop the middle layer
If the website is Shopify and the counter could be, Shopify POS runs the till off the same catalogue as the store, so there’s nothing to sync. It’s included with every Shopify plan; POS Pro adds staff roles, smart inventory and omnichannel features per location. The cost is the switch: new hardware, new card processing, and staff retraining.
Where it doesn’t fit: you keep Square or Clover for any reason, or you also sell on a marketplace.
6. Square Online: the same move from the other side
Square Online is Square’s own storefront, sharing the catalogue with the till. Free with a Square account, with processing fees per sale. For a shop whose only online presence is a simple store, it removes the sync problem rather than solving it.
Where it doesn’t fit: you want WooCommerce, Shopify or a marketplace, or a storefront with more control than Square Online gives.
7. Zoho Inventory: if the books come first
Zoho Inventory has no till integration, which makes it an odd alternative until the problem is the accounts rather than the counter. It syncs Shopify, Amazon, eBay, Etsy and WooCommerce with purchase orders, serial tracking and native Zoho Books, QuickBooks Online and Xero. Free to 50 orders a month, then $29 a month billed annually for 500.
Where it doesn’t fit: no Square, Clover or Lightspeed. US prices confirmed through third-party listings. Source: zoho.com/inventory/pricing, capterra.com.
Best alternative by till
- Square: QuickSync, Trunk, Nembol and Thrive all connect it. Pick QuickSync for a fixed bill and marketplaces, Trunk for bundles, Thrive for purchase orders. Shopify + Square.
- Clover: QuickSync and Thrive. Clover pushes stock and orders to QuickSync through a single endpoint the moment they happen. Clover integration and Clover inventory management.
- Lightspeed: QuickSync, with one caveat it publishes: Lightspeed marks a sale shipped but discards the tracking number.
- Shopify POS: you don’t need a sync tool for the till; you need one for the marketplaces. POS inventory management.
Switching without double-counting
- Make every SKU unique on both sides. Every tool here matches by SKU. Two items sharing one on the till can’t sync.
- Disconnect SKU IQ before the first write. Two tools writing stock to the same store is how counts double. Read-only first, then one writer.
- Pick the till as the source of truth. It’s usually the count somebody physically checked.
- Watch for a day. Compare the twenty best sellers on the till and the website before switching the sync on.
