Syncio alternative for multi store sync
Syncio is the established app in this category: 152 reviews and years of history. StoreTwin is two months old and does a narrower job - keeping one merchant's stores identical and proving it with a daily audit. This page compares the two by the work each does, so you can tell which job is yours. Every Syncio figure was read from their public App Store listing, pricing page and help centre on 20 August 2026; prices and counts move, so check their pages before you decide.

Direction of sync, and what is copied
Both apps copy a catalogue one way, from a source store into a destination store. Syncio then adds flows that travel back: orders forwarded to the source store for fulfilment, payouts with commissions and revenue splits, a marketplace for finding stores to sell for, and WooCommerce alongside Shopify. That shape fits two businesses trading with each other.
StoreTwin syncs stock, variants, product fields and your own metafields between stores that belong to the same merchant, one way, and never touches orders or customers: those permissions are not requested at install. If orders or money need to move between the stores, that is Syncio's product, not ours.
Speed
Speed does not separate the two apps: their listing says "real-time", and ours does too. Our claim, in the words of our listing: a change in the store that owns the catalogue reaches the other store within seconds - stock, variants, fields and your own metafields. Images are the deliberate exception: they are copied when a product is first created in the receiving store, because re-copying images into an existing pair would duplicate them, so image differences are reported and left alone.
The audit: the part we built this app around
Copying a catalogue and knowing the copies still match are two different jobs. StoreTwin does the second one on a schedule: every hour it re-checks what changed, once a day it compares the complete catalogue of both stores product by product and field by field, and the report names every difference with both values. When syncing is on, the difference is repaired and the next check shows the stores match; when it is off, you get the list and nothing is written. How the audit works.
As of 20 August 2026, neither Syncio's listing nor their pricing page lists a feature that re-checks copies after the fact. Their own help article on incorrect inventory numbers, live the same day, ends with: "Please contact support to manually resync the entire inventory to the new location quantity." With StoreTwin, finding and repairing that class of drift is what the app does on its own, and the report is the proof.
Who pays, at their published prices
Syncio bills both sides of a pair. The destination store picks a plan by product count; the source store is on a performance plan billed by monthly orders that contain synced products; product fields, orders, payouts and metafields are separate add-ons. All figures below were read from syncio.co/pricing and their App Store listing on 20 August 2026.
| What is billed | Syncio (20 Aug 2026) | StoreTwin |
|---|---|---|
| Destination store | Free up to 25 products, then $19/mo (26-100), $29/mo (up to 500), $39/mo (up to 1,000), $69/mo (3,000), $99/mo (5,000), $129/mo (10,000), custom above that | Free Audit $0 (whole-catalogue audit, 25 synced products), Standard $29/mo (up to 1,000 synced), Pro $49/mo (no product limit) |
| Source store | Free only up to 10 orders with synced products per month, then $19/mo (11-100 orders), $49/mo (101-1,000), $99/mo (1,001-10,000) | Always free, whatever your order volume |
| Product fields (title, images, price, tags) | Product Settings add-on, +$19/mo | Included on every plan |
| Metafields | +$9/mo for ten definitions, +$29/mo unlimited | Included on every plan |
| Orders and payouts | Order Sync +$22/mo, Payouts +$9/mo (their product, real work) | Not offered: we never read orders |
| Connections | Unlimited source stores | Unlimited on every plan, free included |
A worked example at those prices: a destination store syncing 1,000 products with product fields and ten metafield definitions is $39 + $19 + $9 = $67/mo with Syncio, plus the source store's performance tier once it passes 10 orders a month. The same pair is $29/mo with StoreTwin, total. Our pricing in full.
What StoreTwin never does
Nothing is ever deleted in either store: unchecking a product stops future copies and touches nothing that exists, and a product removed on one side is reported as a difference, not mirrored as a deletion. Prices are not synced either: a price is set once when a product is first created in the receiving store, because a variant without one would go on sale at zero, and it is never updated after that. Stores that sell in different markets price independently, and a sync that keeps overwriting prices turns a currency decision into an accident. And nothing is copied at all until you allow it twice: a new connection starts in checking-only mode and shows you the report first.
When Syncio is the better choice
Take Syncio if orders and money have to travel between the stores: wholesale, consignment, dropshipping suppliers, payouts with revenue splits, finding partner stores through their marketplace, or a WooCommerce side. Those are real products we do not have. Their 152 reviews and years in the market are also worth something ours cannot offer yet: StoreTwin is two months old and has no reviews at the time of writing.
Take StoreTwin if both stores are yours and the job is a catalogue that stays identical with proof: one price on the receiving store, every synced field and your own metafields included, sources free, and a daily report that names each difference instead of a status light.
Questions merchants ask when comparing
Can I try StoreTwin without switching? Yes. The free plan audits your whole catalogue, including one that another app is syncing, and the audit writes nothing. You can read a week of reports on your existing setup before changing anything. How to verify a sync you already run.
Does the source store ever pay? No. The receiving store holds the plan; source stores are always free and connections are unlimited on every plan.
Does StoreTwin move orders back to my main store? No, and it never will under the current permissions: the app does not request access to orders or customers at all. If you need order forwarding, use Syncio.
What about two-way sync? StoreTwin is one way by design: one store owns the catalogue, the other receives it, and the audit checks both. Why we chose one-way, and when two-way is right.
