Common questions

Practice management integrations FAQs

Which software does Engager integrate with?

Engager integrates with Xero, QuickBooks, FreeAgent, TaxCalc, Xenon Connect, HMRC, Companies House, Xama, Armalytix, Adfin, Crezco and RQ.

Do integrations cost extra?

Engager does not charge extra for most integrations. Two-way Xero sync is an optional add-on at £4 a month. Partner services such as Adfin, Xama, Armalytix, Crezco and RQ may have their own fees, and you need an active subscription to any accounting software you connect. See Engager pricing.

What syncs between Engager and Xero, QuickBooks or FreeAgent?

Client details and invoices sync both ways. Invoices you create in Engager appear in your accounting software, and client details stay consistent across both systems.

How do I connect an integration?

In Engager, go to Settings, choose the integration and follow the on-screen steps to authorise it. Companies House needs no setup and is available from the moment you sign up. Visit the help centre.

Can I request HMRC agent authorisation from Engager?

Yes. The HMRC integration lets you request and track agent authorisations for Self Assessment, PAYE and CIS, MTD VAT, MTD IT and Corporation Tax without logging in to HMRC separately. How the HMRC integration works.

Is my client data secure?

Your data is hosted in the UK with ongoing backups and encryption, and Engager is Cyber Essentials certified. View our Cyber Essentials certificate.
