Why Zynk
Less rekeying, fewer errors, faster answers
Set up a standard integration yourself with Autopilot, have our team or a solutions partner build a complex one with Workflow. Finally, just add Insights AI to ask questions across all your systems from the AI assistant you already use.
Orders that post themselves
Orders, invoices, credit notes and payments go into Sage, Xero or QuickBooks automatically, so nobody spends hours a week copying data between systems.
Stock levels you can trust
Stock and prices sync back to your shops and marketplaces on a schedule you control, so you don't sell what you haven't got.
Answers without the spreadsheet
Ask Claude, ChatGPT, Copilot or Gemini which customers are overdue or how this month compares to last, and get one answer from your connected systems.

What does Zynk do?
Zynk automatically moves data between your accounting system and the other platforms you run your business on: ecommerce stores, marketplaces, CRMs, EPOS, warehouse and 3PL systems.
Orders, invoices, customers, payments and stock levels flow between systems on a schedule you control, so your finance team stops rekeying data and your figures stay accurate everywhere. Most of our customers come to us because someone is spending several hours a week copying data between systems by hand, or because errors from manual entry are causing problems downstream.
With Insights AI, you can also report on that data by asking questions in plain English from the AI assistant you already use, with answers drawn live from all your connected systems at once.
Which versions of Sage do you support?
We work with Sage 50 UK, Sage 50 US, Sage 50 Canada, Sage 200, Sage Accounting, Sage Intacct and Sage 200 Evolution.
Sage integration is our specialism rather than a side line; we've been building on the Sage platform since 2002, and we support the full range of record types rather than just sales orders. If you're on a different accounting platform, get in touch and we'll tell you honestly whether we can help.
What can I connect Sage to?
Our most popular connectors include Shopify, WooCommerce, Magento, Amazon, eBay, BigCommerce, Salesforce and HubSpot, but the full list runs to well over 100 systems across ecommerce, CRM, marketplaces, EPOS, logistics and payments.
Don't see yours? We build custom connectors regularly, and our platform is designed to talk to anything with an API, database or file feed.
What's the difference between Zynk Autopilot, Workflow and Insights AI?
Autopilot and Workflow move data between your systems. Insights AI lets you ask questions of it.
Zynk Autopilot is cloud-based and self-serve. You connect your systems, choose how you want data to flow, and you're live, often within the hour, with no software to install. It's built for standard processes and suits small and medium businesses who want their integration working quickly.
Zynk Workflow is installed on your own infrastructure and is fully configurable. If you have complex business rules, unusual data mappings, high volumes, or you need to connect several systems at once, this is the one. Workflow projects are scoped, built and tested with our team before go-live.
Zynk Insights AI doesn't move data at all. It's an MCP server that connects your accounting, ecommerce and analytics systems to Claude, ChatGPT, Copilot or Gemini, so anyone in the business can ask questions and get one answer across all of them.
Not sure which fits? Tell us what you're trying to connect and we'll point you at the right one, including if that's the cheaper one.
How much does it cost?
Zynk Autopilot starts at £49 per month, with pricing based on transaction volume. You can see the full breakdown on our pricing page.
Zynk Workflow is an annual subscription plus a one-off implementation cost depending on the complexity of your integration. We'll always give you a fixed written quote after scoping; you won't get a surprise invoice halfway through a project.
Zynk Insights AI starts at £49 per user per month, with free onboarding, where we connect your systems and configure Insights for you.
How long does it take to get up and running?
Autopilot: less than an hour. You're configuring it yourself, so the timeline is largely yours.
Workflow: typically 1–4 weeks depending on complexity, longer for large multi-system builds.
Insights AI: once our onboarding team has connected your systems, adding Insights to your AI assistant takes minutes, and your team can start asking straight away.
