Fast Billing Software doesn't ask you to throw anything out. It turns a confirmed sale into a GST tax invoice, then feeds that data straight into the systems you already run — Tally and other accounting, the GST portal, your barcode and POS hardware, WhatsApp and email for follow-up, and Dhruv AI for the questions your reports can't answer. Your accounting stays the book of record; Fast Billing keeps it fed so nothing gets re-keyed.
Each one works off the same live invoice, payment and GST data you capture in GST tax invoicing and payments & receipts — no export files, no double entry.
Confirmed tax invoices post to Tally and other accounting tools as sales vouchers with GST — CGST/SGST/IGST ledgers and all. Customer receipts post as receipt vouchers, credit and debit notes as Cr/Dr notes, and approved supplier bills as purchase vouchers. Your accounting stays the book of record; Fast Billing feeds it operationally so nothing is re-keyed.
Explore accounting syncThe invoice and dispatch details already hold what the GST portal needs. Get GSTR-1/2/3 reconciliation from party-wise GST data, generate the e-way bill from the invoice plus dispatch details, and produce an e-invoice or QR where configured. HSN-to-GST rate maps and bulk GSTIN import keep the tax on every line right the first time.
Explore GST & e-way billRetail counter and B2B billing share one system. Print 1D/2D/QR barcodes on items and invoices, drive TSC thermal printers for labels and receipts, and pair wired or wireless POS scanners so a counter operator can scan to bill. Quick counter (POS) billing runs alongside your tax invoices — one product, both ways of selling.
Explore barcode & POSSend the invoice the moment it's raised. Email invoices, statements and receipts to customers, then chase what's owed with payment follow-up reminders — overdue and outstanding — on WhatsApp, SMS and email. You decide who gets what, and when, so the collections nudge goes out without anyone remembering to send it.
Explore WhatsApp & emailThe Fast Suite's own AI and BI module, over your live billing data. A role dashboard for outstanding, overdue, GST exposure and sales trends; AI insight summaries that read like a review note; and plain-English questions answered through a read-only sandbox — SELECT-only, whitelisted views. It also clusters free-text payment and remark notes into recurring themes.
Explore Dhruv AIFast Billing shares one platform and one database engine with the other Fast products. When they run together, an order or a dispatch flows into a tax invoice without an interface layer — and a supplier bill flows in for approval.
A confirmed order acceptance becomes the source document a tax invoice is raised against, so what was quoted and ordered flows to billing without re-entry. Sales and billing read the same customer and item masters — the invoice carries the right party, price and terms every time.
fastcrmsoftware.comStock leaves the building at dispatch, not at the invoice — so billing is a financial event, not a stock one. A completed dispatch or delivery challan is what the invoice bills against, and the double-bill guard makes sure a dispatched quantity can't be invoiced twice.
fastinventorysoftware.comPurchase orders and goods receipts feed supplier-bill approval — the accounts-payable side of billing. An approved supplier bill posts to your accounts as a purchase voucher, so payables and receivables both flow from the same platform without a second data entry.
fasterpsoftware.comStandalone-capable by design. Everything you need to bill — GST tax invoices, delivery challans, credit and debit notes, payments and follow-up, light accounts, project billing and POS — is inside Fast Billing Software itself. The CRM, Inventory and ERP links switch on when those products are licensed; the accounting sync, GST, hardware, WhatsApp and Dhruv AI integrations work either way.
In a 30-minute demo we'll raise a GST tax invoice, post it to your accounts, generate the e-way bill, print it on a thermal printer and WhatsApp the follow-up — on one live bill.
