Stop typing the same record into two systems
Codexlava connects the systems a business already runs — accounting, CRM, payments and Microsoft 365 — to each other and to your own custom software, website or shop. Built on each vendor's official API, tested against their sandbox, and built to tell someone when it fails.
Five we work with
Another system? If it has a documented API, it can usually be connected — ask.
Xero · Accounting
Invoices, bills, contacts and payments written to Xero from your own system through the Xero API, so finance stops re-keying what the website or app already knows.
QuickBooks · Accounting
The same for QuickBooks Online: sales, invoices and customers synced through its accounting API, with failures reported rather than silently dropped.
HubSpot · CRM
Contacts, companies and deals created or updated in HubSpot from your forms, app or shop, so sales see every enquiry in one place.
Stripe · Payments
Checkout, subscriptions, refunds and invoices through Stripe, with webhooks keeping your own records in step with what Stripe has actually charged.
Microsoft 365 · Workplace
Sign-in with your staff's Microsoft accounts, and documents, calendars and email reached through Microsoft Graph — inside the tools your team already uses.
Integrations that keep working
-
Map the data
Which records move, in which direction, which system wins when two disagree, and what happens to the ones already there.
-
Use the official API
Each vendor's documented API, with OAuth or a revocable API key, never scraping or a shared password, so the connection survives the vendor's next redesign.
-
Plan for failure
Retries, a queue for work that cannot run yet, and an alert when something fails — so a missed invoice is a notification, not a surprise at month end.
-
Test against a sandbox
Xero, QuickBooks, HubSpot and Stripe all offer test environments. Integrations are proven there before they touch your live accounts.
-
Hand over with a runbook
What to do when a token expires or a sync fails, written down, so your team is not dependent on us to keep it running.
