When the invoice is generated, an export file of billable charges is also created, so that charges and breakdown by general ledger account can be automatically fed into the laboratory’s Accounts/Receivable system. Invoices, including the charge detail, remain online for inquiry purposes. The entire invoice can be backed out and regenerated if changes are to be made, spawning an updated credit memo to A/R. Most HORIZON users generate invoices directly from LIMS, but you still have the option of just passing the A/R file through and using the existing billing features in your accounting system.
Accounting systems are highly standardized from an integration standpoint, so the interfacing technique is quite generic. HORIZON has been interfaced to more than a dozen different accounting systems, including both text file and HL7 uploads.
