In most calibration labs billing is a second job. The work is completed, the certificate is issued, and then someone re-types the customer, the instruments and the charges into an invoice template. Every re-typed line is a chance for a wrong amount, a missed instrument or a duplicate bill.
Calibration lab invoicing software should remove that second data entry entirely, because the information needed for the invoice already exists in the receipt and the job.
Invoices Built from the Receipt
In QuantumCals, invoices are generated from the same receipt that drove the work. The customer, certificate customer, receipt number and the instruments that were actually calibrated are carried across automatically, so the invoice matches the certificate by construction.
Three Invoice Views for Different Needs
- Per-receipt invoice: the standard invoice for one receipt, suitable for most single-visit jobs.
- Annexure invoice: a detailed schedule of instruments and charges that accompanies the main invoice when a customer needs line-by-line support for their accounts team.
- Consolidated invoice: one invoice that rolls up several receipts for a customer who prefers a single monthly bill.
Avoiding Double Billing
Because each invoice is tied to its receipt and samples, the system can show which instruments have already been billed. This is the main protection against double billing when a customer sends a second batch that partly overlaps an earlier one.
Tracking Payments
Once an invoice is raised, the lab can record payments against it and see what is still outstanding. The accounts team sees the same numbers the lab manager sees, so questions about payment status are answered without a phone call to the front desk.
What to Check Before Your Next Invoice Run
- Confirm the certificate customer, since it may differ from the paying customer.
- Check the GST details and the billing address on the customer record.
- Make sure every completed sample is linked to the receipt so nothing is left unbilled.
