IT Boffins is a certified Xero developer partner based in Milton Keynes. We build custom Xero API integrations connecting CRMs (HubSpot, Pipedrive) and custom billing databases to automate invoice syncing, customer portals, payments, and multi-line ledger mappings.
Xero is strongest when it is connected to the systems that already run your business. As experienced Xero integration developers, we build the missing bridge between HubSpot, custom CRMs, quote tools, customer portals, billing databases, and Xero accounts.

CRM to Xero Automation
If your team creates a quote in one system, retypes customer details into Xero, manually checks VAT, then later reconciles the payment somewhere else, there is a better way.
We connect custom CRM applications or off-the-shelf software to Xero. As dedicated Xero developer partners based in Milton Keynes, we build integrations so that your invoice line items, tax codes, client contacts, and invoice payments move seamlessly.
What We Build
Invoice sync
Create draft or approved invoices from your CRM, website or portal.
Payment workflows
Connect card, BACS or portal payments back to the correct Xero records.
Live dashboards
Show useful financial data on internal dashboards or office information screens.
Custom connectors
Bridge Xero to legacy databases, quote tools, e-commerce and internal systems.
ShipMyCar Case Study
ShipMyCar handles high-volume quotes, customer portals, payments and operational workflows. We helped build custom systems that connect business operations with accounting workflows, reducing duplicate entry and making financial data easier to manage.
That is the work we enjoy: connecting the real business process to Xero so the accounts are not a separate manual chore at the end of the day.
Built With Control
A finance integration should be boring in the best possible way: predictable, logged, permission-aware and easy to understand when something needs checking.
- Official API connection patterns.
- Clear handling for failed syncs and duplicates.
- Permission boundaries for sensitive financial data.
Common Questions
Can you build custom Xero integrations?
Yes. We build custom integrations using the Xero API, including CRM to Xero invoice flows, payment allocation, reporting, dashboards and operational tools.
Do you only work with Xero?
No. Xero is often one part of a wider workflow. We can connect your website, CRM, quote system, portal, spreadsheets, payment provider or internal database to Xero.
Is a Xero API integration secure?
Yes, when it is built properly. We use official OAuth-style connection flows, controlled permissions, server-side handling and clear audit trails.
Can you fix an existing Xero integration?
Yes. We can inspect failed syncs, duplicate invoices, tax-code problems, missing contact links, poor reconciliation logic and unreliable third-party connectors.
