Frequently Asked Questions
Common questions about our Xero development services and integration solutions
What does a Xero developer do?
A Xero developer builds custom software that connects to Xero using the official Xero API. This includes bespoke integrations between Xero and your CRM, e-commerce, inventory or payroll systems, custom add-ons that extend Xero's functionality, automated invoicing and reconciliation workflows, and advanced financial reporting dashboards tailored to your business.
Why hire an approved Xero developer rather than a general developer?
Approved Xero developers have completed Xero's certification process and build to Xero's official API standards, OAuth 2.0 security requirements, and rate-limit best practices. This means integrations that are secure, compliant, stable through Xero's API changes, and eligible for the Xero App Store. Synergi Tech has been Xero certified for over 12 years and has delivered 35+ Xero integrations.
How much does it cost to hire a Xero developer in the UK?
Cost depends on the complexity of the integration. A simple one-way data sync is far less involved than a bespoke multi-system add-on with custom reporting. We scope every project up front and provide a fixed, transparent quote after a free consultation, so there are no surprises.
How long does a typical Xero integration project take?
Most Xero integrations take 2-8 weeks from initial consultation to deployment. Simple API connections may be completed in 2-3 weeks, while complex multi-system integrations with custom reporting can take 6-8 weeks. We provide a detailed timeline during the planning phase.
Can you integrate Xero with our existing business systems?
Yes. We specialise in connecting Xero with CRM platforms, e-commerce stores, inventory management, payroll software, and bespoke applications. Our experience covers integrations with Salesforce, Shopify, WooCommerce, GoCardless, Stripe, and many other popular business tools.
Do you provide ongoing support after the Xero integration is complete?
Yes. We offer ongoing support including system monitoring, regular updates, troubleshooting, and feature enhancements. Support packages range from basic maintenance to 24/7 monitoring with guaranteed response times, ensuring your Xero integration keeps performing as Xero's API evolves.
