FreeAgent WooCommerce plugins compared 2026 – the honest options

If you keep your books in FreeAgent and sell through WooCommerce, the choice is narrower than it looks. FreeAgent has no connector you can switch on inside its own dashboard – everything happens in a WordPress plugin. In practice that leaves the paid extension sold on the Woo Marketplace, Devikit FREE and Devikit PRO. Here is how the three compare, table first.

Comparison table

Devikit publishes a free version you can install in WordPress today. The Woo Marketplace extension has no free tier, only a 30-day money-back guarantee on the subscription.

What are your real options

• A connector inside FreeAgent – does not exist. FreeAgent’s WooCommerce integration page and its list of supported integrations both point you to a plugin you install in WordPress. Nothing is switched on from the FreeAgent side.
• FreeAgent Sync for WooCommerce – the paid extension listed by FreeAgent and sold on the Woo Marketplace. This is the incumbent and the only direct plugin competitor we could verify.
• Devikit FREE and PRO – start with manual invoicing at no cost, move up to PRO when volume, refunds or emails need automating.
• Zapier and other no-code tools – possible, but limited for invoicing. Worth understanding before you build a workflow on top of one.
• Payout summary tools like A2X or Link My Books – a different job entirely, and neither posts to FreeAgent. More on that below.

There is no WooCommerce connector inside FreeAgent

This is the first thing to get straight, because FreeAgent’s marketing makes the integration sound like something you enable in your account. It is not. The “Connect now” button on FreeAgent’s WooCommerce page sends you to the Woo Marketplace, and the setup steps are the usual WordPress routine: download a ZIP, upload it under Plugins, activate, then configure under WooCommerce settings.

Every option here also needs a FreeAgent developer application. You create it at dev.freeagent.com, copy the OAuth identifier and secret into the plugin and authorise the connection once. That applies to the Woo Marketplace extension and to Devikit alike – it is how the FreeAgent API works, not a quirk of any one plugin.

Making Tax Digital sits outside all of this. FreeAgent is HMRC-recognised and files your VAT return directly, so the plugin’s only job is to get sales, VAT rates and EC status into FreeAgent correctly. No WooCommerce plugin files anything with HMRC on your behalf.

FreeAgent Sync for WooCommerce

FreeAgent Sync for WooCommerce is built by The team at PIE and sold on the Woo Marketplace at $79 for a one-year plan, or $126.40 for two years. At the time of writing it is on version 1.6.10 with 100+ active installs and an average rating of 3.0 from five reviews.

It works in two modes. Summarised mode, which the vendor recommends, posts one set of daily invoices grouped by tax rate, currency and sales type, and handles EC goods and services, multi-currency and VAT MOSS. Detailed mode creates an invoice and a contact per order, can mark invoices as sent, and can apply payments automatically when an order moves to processing or completed. A custom invoice reference is supported as long as it contains the order ID.

Two things are worth knowing before you buy. First, per-order invoicing in detailed mode triggers when the order is created rather than on statuses you pick, and the documentation steers larger stores towards summarised mode specifically to avoid hitting FreeAgent API rate limits. Second, there is a documented rounding issue: WooCommerce can hold more than two decimal places while FreeAgent rounds each line to two, so totals can differ by a penny. The vendor lists workarounds rather than a fix, and one of the public reviews is about exactly this.

The documentation does not describe a VAT number field at checkout, customer-facing PDF downloads in My Account, bulk actions across selected orders, or credit notes tied to individual refunds. Credit notes do appear, but through a daily hook in summarised mode. We have marked these as “not in the documentation” rather than as confirmed gaps.

Zapier, no-code tools and payout summaries

Zapier is often suggested as the flexible route, and it is a poor fit here. The FreeAgent app on Zapier publishes only two actions, Create Contact and Create Task. There is no action to create an invoice, so an order in WooCommerce cannot become a FreeAgent invoice through Zapier alone. Zoho Flow does list Create Invoice and Email an Invoice for FreeAgent, so a no-code path exists – it just means paying for and maintaining a second platform, with per-task pricing on top of your store.

The e-commerce accounting tools people usually name in the same breath solve a different problem. Link My Books and A2X reconcile payout settlements into your ledger, and both publish Xero and QuickBooks as their destinations – FreeAgent is not on either list. They are not an alternative to a WooCommerce-to-FreeAgent invoicing plugin.

Devikit FREE and PRO

FREE covers manual invoicing from the order edit screen, the OAuth 2.0 connection with your own developer app, find-or-create contact mapping by email, line-level VAT read from your WooCommerce tax settings, UK/Non-EC and Reverse Charge defaults, a VAT number field that works on both classic and Block checkout, per-SKU FreeAgent item types, payment terms and bank account for remittance, and invoice PDFs in the order metabox and a My Account tab. It also warns you on the order screen when the FreeAgent total and the WooCommerce total drift apart after rounding. There is no status automation, no credit notes, no store-sent emails and no author support.

PRO costs £79.00 ex. VAT / year and adds the automation layer: invoice queueing on the order statuses you choose, automatic credit notes when an order reaches Refunded, daily rollup and grouped invoicing for high volume, automatic payment recording, invoice delivery through FreeAgent templates or as a WooCommerce email with the PDF attached, bulk actions including ZIP export of PDFs, custom reference patterns, nominal category mapping, online payment links for Stripe, PayPal, GoCardless and Tyl, and EC VAT MOSS defaults store-wide and per product. PRO installs on top of a working FREE version, so the FreeAgent connection is not set up twice. The full configuration walkthrough is in the documentation.

One honest detail from the same documentation: partial refunds that do not move the order to Refunded also do not trigger a credit note automatically.

Devikit against the Woo Marketplace extension

Both plugins run on the same FreeAgent OAuth API and both cover the core job of turning orders into invoices. The differences are in how you start, what happens around the invoice, and who answers when something breaks.

• Cost and currency – Devikit PRO is £79.00 ex. VAT / year, billed in sterling. The Woo Marketplace extension is $79 a year, so your actual cost moves with the exchange rate. Neither caps how many invoices you create.
• How you start – with Devikit you install FREE, connect FreeAgent and issue real invoices before spending anything. The Woo Marketplace route is a paid subscription up front, backed by a 30-day money-back guarantee.
• Customer-facing work – Devikit PRO sends the invoice from WooCommerce with the PDF attached and exposes PDFs in My Account. The Marketplace extension sends through FreeAgent, and its documentation does not cover customer downloads in the store.
• B2B capture – the checkout VAT number field is in Devikit’s free tier and is not documented for the Marketplace extension. If you sell to VAT-registered businesses, that changes what lands on the FreeAgent contact.
• Ecosystem – buying on the Woo Marketplace keeps billing, updates and support inside your existing Woo account, which is a genuine convenience if you already run several Marketplace extensions.

The penny rounding problem is worth a separate note, because it is not vendor-specific. It comes from WooCommerce and FreeAgent rounding at different points, and both vendors document the same mitigation: set WooCommerce to two decimal places and review the tax rounding setting. Devikit flags the mismatch on the order and withholds automated customer emails until it is resolved, which limits the damage rather than removing the cause.

What to choose in practice

• A handful of orders a week, invoiced by hand – Devikit FREE. There is no connector inside FreeAgent to fall back on, and paying for automation you will not use makes little sense.
• High-volume B2C where you want a clean ledger, not thousands of entries – daily rollup in either plugin. The Marketplace extension’s summarised mode is its strongest feature; Devikit PRO does the same and still lets you invoice individual orders when you need to.
• B2B sales with VAT numbers and Reverse Charge – Devikit, because the checkout VAT field and EC classification are built in from the free tier upwards.
• Refunds are a regular part of the business – Devikit PRO, for credit notes tied to the individual order rather than a daily summary.
• You already buy several extensions on the Woo Marketplace – one renewal date and one support desk is a fair reason to stay there.
• You want to test the FreeAgent API against your own store first – install Devikit FREE, issue a few invoices, then decide whether automation is worth £79.00 ex. VAT / year.

Summary

FreeAgent and WooCommerce is a thin market. There is no connector in the FreeAgent dashboard, no-code tools cannot create FreeAgent invoices without a paid second platform, and the payout summary tools do not support FreeAgent at all. That leaves one established paid extension on the Woo Marketplace and the Devikit line. The Marketplace extension is strong on summarised daily invoicing and weaker on the customer-facing side; Devikit gives you a free starting point, a sterling price for PRO, checkout VAT capture from day one and per-order credit notes. Whichever you pick, run a few test orders before switching automation on.
