If your team enters a completed job into one system and then types the same details into accounting software, an integration may help. The starting point is deciding which records should move and who checks them—not simply connecting two accounts.
Check the exact accounting product
Xero provides an Accounting API for supported accounting functions. Sage offers different products and developer interfaces, so identify the exact product, version and country configuration before promising a connection. Access rights, supported operations and any commercial conditions need checking for the proposed account.
Decide which system controls each record
Your job management software might control the job description while the accounting system controls invoice status. Record those responsibilities explicitly. Agree how customer identifiers are matched, what happens when an address changes and whether an approved job creates a draft invoice or a later accounting action.
A practical job-to-invoice example
A supervisor marks a job ready for invoicing. An authorised member of staff checks the customer and charge lines. The integration sends the approved information and stores the returned accounting reference. If the transfer fails, the job remains visibly pending rather than appearing complete. This is an example workflow to scope and test, not a claim that every setup supports it unchanged.
How do we avoid duplicate invoices?
Use stable references and keep a record of transfer outcomes. A timeout does not always mean the accounting system rejected the request. Before retrying, establish whether it already processed the transaction. Test connection failures, repeated requests and reconciliation with representative records.
What should we prepare before development?
Bring sample records, your current invoice process and details of the accounting product. Include tax treatment, currencies and credit-note requirements where relevant, with approval from the person responsible for your accounts. Agree permission boundaries, monitoring, support and the handling of supplier API changes.
