How do I make a GST bill on my phone?
Open counter billing on your phone and search an item by name or code, or scan its barcode with the camera. Tap the size or colour if it has one. Press Pay, pick cash, UPI, card or udhaar, and the bill is done.
GST is worked out from the HSN code and rate you set on each product. A bill to a business can carry the buyer's GSTIN, and Slaby picks CGST + SGST or IGST from the place of supply.
GST billing and B2B invoicesCan I bill without internet?
Yes, once you switch on offline billing in counter settings. When the connection drops, cash and UPI bills are saved on the billing device with a provisional number and sent on their own when the internet is back.
A bill that can't go through, for example because the last piece sold online in the meantime, waits under Needs attention. Nothing is dropped and nothing is billed twice.
How offline billing worksWhich devices, scanners and printers work?
Any phone, tablet or PC with a modern browser. You can install counter billing like an app, so it opens full screen straight to the bill, and keep the screen awake while you bill. On a tablet the items show as photo tiles you tap; on a PC every action has a key.
No billing machine is needed. Most USB or Bluetooth barcode scanners work, and so does the phone camera. Bills print straight to a USB or Bluetooth thermal printer, through the browser's print window on any 58 mm, 80 mm or A4 printer, or go out as a WhatsApp link and PDF.
- Customer display: open a second window for the customer's screen on the same computer. It shows the items, the total, your UPI QR and a thank-you.
- Keyboard billing: F2 to pay, F4 for exact cash, Ctrl+K to find anything.
How do I track udhaar?
Give a customer a credit limit, then choose udhaar as the payment at the counter. Their balance builds up in an udhaar book that shows who owes what and how old each amount is.
When they pay, enter the amount and it clears their oldest bills first. To remind them, open a ready WhatsApp message with their statement link and a UPI payment link, and press send yourself.
The udhaar bookCan my shop and my website share one stock?
Yes. Slaby is also an online store, and the counter and the website take from the same stock. When the last piece sells at the counter, the website shows it sold out within seconds, so you don't sell it twice.
Pieces you keep only for the shop can be hidden from the website with one switch per product or size.
Billing with an online store on one stockWhat does my accountant get?
Reports made from your bills: a sales register, GSTR-1 in Excel with a JSON file for the GST portal, a GSTR-3B summary, an HSN summary, and sales by payment mode, item and staff member. Choose website sales, counter sales or both.
If your accountant uses Tally, download the same bills as a Tally XML file to import. Slaby prepares these files; it does not file returns. Your CA checks and files them.

बिलिंग सॉफ़्टवेयर: आम सवाल
क्या मैं फ़ोन से GST बिल बना सकता हूँ?
हाँ। फ़ोन पर काउंटर बिलिंग खोलिए, आइटम खोजिए या कैमरे से बारकोड स्कैन कीजिए, पेमेंट चुनिए और बिल प्रिंट कीजिए या WhatsApp पर भेजिए। GST हर प्रोडक्ट के HSN और रेट से अपने आप लगता है।
इंटरनेट बंद हो जाए तो क्या होगा?
ऑफ़लाइन बिलिंग चालू होने पर कैश और UPI बिल डिवाइस पर सेव होते हैं और इंटरनेट लौटते ही अपने आप भेजे जाते हैं। कोई बिल छूटता नहीं, और कोई बिल दो बार नहीं बनता।
उधार का हिसाब कैसे रखूँ?
ग्राहक की उधार लिमिट रखिए और काउंटर पर पेमेंट में उधार चुनिए। उधार बुक में दिखता है कि किसका कितना बाकी है। WhatsApp पर याद दिलाने का मैसेज तैयार मिलता है, भेजते आप ख़ुद हैं।
इसकी क़ीमत क्या है?
काउंटर बिलिंग हर पेड प्लान में शामिल है, Lite (₹299 महीना) से। शुरुआत फ़्री ट्रायल से होती है, कार्ड की ज़रूरत नहीं।
What do shop owners ask about Slaby's billing software?
Is Slaby's billing software free?
No. Counter billing comes with every paid plan, from Lite at ₹299 a month. Every new store starts with a free trial, and no card is needed to start it.
Do I need to install anything?
No. Billing runs in the browser on your phone, tablet or PC. You can install it like an app from the browser so it opens full screen, but there is nothing to download from an app store.
Can I make B2B GST invoices with the buyer's GSTIN?
Yes. Add the buyer's GSTIN at the counter and Slaby checks its format and check digit, prints both GSTINs on the tax invoice and shows the place of supply. Goods handed over at your counter are taxed as CGST + SGST; goods you deliver to another state are taxed as IGST.
Does Slaby generate e-invoices (IRN) or e-way bills?
Not yet. Slaby makes GST tax invoices and GSTR-1 / GSTR-3B files for your accountant, but it does not generate IRN e-invoices or e-way bills, and it does not file returns.
Can I print bills on a thermal printer?
Yes. Connect a USB thermal printer from Chrome or Edge on a computer, or a Bluetooth printer from Chrome on Android, and bills print straight away, with paper cut and cash drawer if your printer has them. Any other printer works through the browser's print window, and a bill can also go out as a WhatsApp link and PDF.
Can my cashier bill without seeing my reports?
Yes. Give them the Cashier role: they can bill, hold bills and take payments, while discounts, reports and settings stay with you unless you allow them. If you do let them give discounts, you can cap how much. A cashier needs a staff login of their own, and the day book shows each cashier's cash, discounts and cancelled bills.
Can I cancel or edit a bill after it's made?
Yes. Cancel a counter bill with a reason: the items go back into stock and the payment is reversed, and a bill from an earlier GST period is reversed with a credit note. You can also let cashiers edit a bill for a few minutes after it is made; that setting is off until you switch it on.
Can I sell loose items by kg or litre?
Not yet. Quantities at the counter are whole pieces today. Selling by weight with weighing-scale barcodes is being designed and is not available.
Does it work with Tally?
Yes. Download your bills, credit notes and udhaar payments as a Tally XML file from Reports and import it in Tally. Set the ledger names once in Settings so they match your Tally company.
Can I download all my data?
Yes. The store owner can download items, customers, bills, the udhaar ledger and the day book as one Excel workbook or a ZIP of CSV files from Settings → Export & backup.
