Many workshops still type the same information twice: once on the quotation and again on the invoice. That wastes time and invites errors. A better approach is one workflow from quote to job to invoice.
Quote first, convert later
Create a quotation with labour and parts. When the customer approves, convert it into a job—no need to re-enter customer, vehicle, or line items. GRX supports this flow so your team stays in one place.
Invoice from the job
Once the job is done, generate the invoice from the same record. Amounts and descriptions are already there; you only adjust if something changed. VAT and totals stay consistent.
Audit trail and clarity
Linking quote → job → invoice gives you a clear audit trail. You can see what was quoted, what was done, and what was charged—useful for disputes, warranty, or simply understanding your margins.
