Acumatica eCommerce integration syncs orders, inventory, customers, fulfilments and refunds between Acumatica and storefronts like Shopify, BigCommerce or Amazon. Unusually, Acumatica ships native connectors for major platforms in its Retail edition; ISV connectors and iPaaS options cover other channels, marketplaces and more complex multi-channel architectures.

Acumatica took the road most ERP vendors didn't: first-party storefront connectors (Shopify, BigCommerce, Amazon) built and maintained by Acumatica itself in its Retail-Commerce edition — real-time-ish sync of orders, inventory and fulfilments with support on one throat to choke. For single-storefront merchants, that changes the default.
The ISV and iPaaS options below matter for everything beyond that default: platforms Acumatica doesn't connect natively, marketplace breadth, B2B portals tied to Acumatica pricing, heavy customisation, and multi-channel operations where one integration hub beats three parallel connectors.
Genuinely competitive: Acumatica's Shopify and BigCommerce connectors (and Amazon connectivity) are first-party product, release-synchronised and covered by Acumatica support — evaluate them FIRST if your channels match. Their boundary: channels outside the supported list, complex orchestration (3PLs, POS, subscriptions in one mesh), and edge-case flows like intricate payout reconciliation or bundles, where specialist connectors and iPaaS earn their place.

Most vendors in this category price by quote, so there is no honest list price to quote you. Here is what actually drives your number — and how to get a real one.
3 of the 4 vendors we track in this category publish no list price at all.
List the specific eCommerce connectors outcomes you need — volumes, workflows, countries, systems in the loop — and rank them. Vendor demos are optimised to reframe your requirements around their strengths; a written list keeps the evaluation yours.
Every vendor here “integrates with Acumatica” — the differences are in depth. Ask each to demo the integration against a realistic Acumatica configuration: your entity structure, your fields, your transaction volumes, and what happens when a sync fails.
Look for Acumatica-Certified Application (ACA) and a current listing on the Acumatica Marketplace. Certification doesn't guarantee fit, but it confirms the vendor keeps pace with Acumatica releases — uncertified integrations are where upgrade breakage concentrates.
Ask for two reference customers on Acumatica at your size and in your industry, and ask them what broke in the first year. Implementation quality varies more than product quality in the eCommerce connectors category.
Compare subscription plus implementation plus internal effort — not headline price. Acumatica eCommerce integrations pricing models differ (per user, per volume, per entity), so normalise every quote to your actual usage before comparing.
Start native when your storefront is Shopify, BigCommerce or Amazon and flows are conventional — it's maintained by Acumatica and included in the commerce edition story. Go ISV/iPaaS for unsupported channels, multi-system orchestration, custom field mapping at depth, or when you're consolidating several integrations onto one monitored platform. Many mid-market merchants run native for the main store plus iPaaS for the long tail.
The unglamorous flows: refunds and partial refunds posting correctly, payout/settlement reconciliation against fees, inventory oversell during spikes, and bundle/kit mapping. Demo these specifically — order import always works in demos. Also confirm warehouse and location mapping if you fulfil from multiple sites.
Consumption-based licensing means order lines from commerce channels count toward your resource tier — a Black-Friday-scale spike is a licensing event as well as an ops event. Model peak volumes with your VAR up front, and prefer integrations that batch sensibly without sacrificing the near-real-time inventory sync that prevents oversells.
This comparison currently covers 4 options that work with Acumatica, including k-eCommerce, Kensium Commerce Connector, Celigo. Each links to a detailed profile with features, integrations, pricing and alternatives, and the directory is updated as the market changes.
Most vendors here quote rather than publish. Tell us your Acumatica version, seat count and must-haves and we'll come back with an independent view of what it should cost — and which options are worth quoting against each other.
