The GST sales register report lists every invoice for your accountant. Tax rules change, so confirm rates with your chartered accountant. ## GST invoicing software for service businesses in India Field service management software (FSM) with GST invoices that carry the SAC or HSN code and rate on each line, your own numbering series and a GST sales register for your accountant. For a service business, a wrong invoice costs twice: once in the customer's questions, and again when it has to be reissued. ServicePilot takes the rate and code from the service itself, so the invoice is right when it is raised. ## What goes on the GST invoice - Your details and GSTIN, and the customer's details and GSTIN where they have one. - Each line with its SAC or HSN code, rate and amount. - Tax split as your accountant needs it. - An invoice number from your own series. ## Bill from the contract or the job Raise an invoice from an [AMC contract](https://servicepilot.in/features/amc-contracts/) or a completed job, so the customer, site and services are filled in. Receipts are recorded against the invoice under [payments and collections](https://servicepilot.in/features/payments-and-collections/). ## The GST sales register One report lists every invoice with its taxable value and tax. Your accountant gets the same numbers you see, in one place, instead of a pile of PDFs. ## Billing a visit - The job is completed. - The office raises the invoice with services and parts used. - The customer pays; the receipt is matched. - The register includes it for the month's return. ## Illustrative example: a pest control business billing monthly A business in Kochi bills general pest control under SAC 998531 at 18%. Each month the accountant downloads the GST sales register and compares it to the bank. Invoices raised from completed jobs already carry the code and rate. ## Who it is for Accountants and office staff at GST-registered service businesses. A business that is not registered can leave tax off. ## Related ServicePilot features - [Payments & Collections Record payments against invoices and chase what is overdue](https://servicepilot.in/features/payments-and-collections/) - [AMC Contracts Annual maintenance contracts with plans, covered sites and a visit schedule](https://servicepilot.in/features/amc-contracts/) - [Quotations & Sales Quotations, sales orders and returns with GST on every line](https://servicepilot.in/features/quotations-and-sales/) - [Reports Collections, revenue, receivables ageing, AMC renewals and technician performance](https://servicepilot.in/features/reports/) ## Guides on this topic [Pest Control Pest Control Quotation Format Pest control quotation format with the lines to include: service, area, visits, price, GST, validity and terms.
