What gst eway bill system involves in practice — generation, transporter details, validity, and the relationship between the e-way bill and the invoice it covers.
When an e-way bill is required
Broadly, for the movement of goods where the consignment value exceeds ₹50,000 — in relation to a supply, for reasons other than supply, or for inward supply from an unregistered person.
Intra-state movement is where it gets local: states set their own limits and exemptions for movement within the state, and they are not identical. Check your own state’s notification rather than assuming the general position.
Certain goods are exempt, and there are relaxations for short distances in some circumstances. Where the value is near the threshold, generating one anyway is cheaper than arguing at a checkpoint.
What your billing system needs to get right
- Invoice value that matches the e-way bill. This is the single most common cause of trouble in transit.
- Correct GSTINs for both parties, in valid format.
- HSN on every line, since it is reported on the bill.
- Correct place of delivery, which is not always the customer’s registered address.
- A stable invoice number — the e-way bill references the document, so renumbering after the fact breaks the link.
- Billixo keeps all of these on the invoice by design, so the data the e-way bill needs is already correct and consistent.
Generating one, step by step
- Raise the invoice first. The e-way bill references it, so it has to exist and its value has to be final.
- Log in to the e-way bill portal, or generate from your billing or accounting system if it connects.
- Fill Part A: parties, GSTINs, place of delivery, document number and date, value, HSN, reason for transport.
- Fill Part B: transporter ID, or the vehicle number for own transport.
- Generate, and keep the e-way bill number with the consignment.
- If the vehicle changes mid-journey, update Part B. If validity is running out, extend it within the permitted window rather than letting it lapse.
The mismatch that causes most problems
The value on the e-way bill and the value on the invoice must agree. When they do not, it is almost always because the invoice was amended after the bill was generated, or because someone typed the taxable value where the total was required.
That is a workflow problem rather than a rules problem, and the fix is order of operations: finalise the invoice, then generate, never the other way round.
Validity, and what expiry actually means
Validity runs by distance and is counted in days from generation, with the exact calculation set by rule and differing for over-dimensional cargo.
Expiry is not administrative. Goods moving on an expired e-way bill are treated as moving without one, with the consequences that follow — detention, penalty, and a delay far more expensive than the extension would have been.
Extension is permitted within a window around expiry. The practical discipline is simple: whoever tracks the vehicle should also be watching the clock on the bill.
Credit notes, debit notes, and fixing a wrong invoice
An issued tax invoice is not something to edit. If the value was too high, or goods came back, the correction is a credit note that references the original invoice. If it was too low, a debit note. Both carry their own numbers and both appear in your return.
There is a deadline on the credit note that matters: the adjustment has to be declared by the return for the relevant month of the following financial year, or by the annual return, whichever comes first. Past that, the note exists commercially but the tax cannot be adjusted.
Software that lets you quietly retype an invoice raised last month is not doing you a favour.
Reverse charge, exports and the supplies that behave differently
Not every supply is a straightforward taxable sale. Some notified supplies put the tax liability on the recipient rather than the supplier. Exports and supplies to an SEZ can be made under a bond or LUT without payment of tax, or with tax and a refund claimed afterwards. Composition dealers cannot charge tax at all and must say so on the bill.
Each of these changes what the invoice has to say — the reverse charge marking, the LUT reference, the "composition taxable person" declaration. They are not exotic cases; most businesses hit at least one.
The fields are on the invoice in Billixo whether or not you use them, so the day you need one you are not looking for a workaround.
The AI, and what it is actually for
The useful application of AI to billing is not a chatbot. It is the twenty minutes a day spent retyping things that already exist on paper.
- Scan a supplier bill. Photograph it; the lines, the GSTIN, the tax and the totals come back as a draft you check rather than a form you fill.
- Find the HSN code. Describe the product in plain words and get a code to confirm, instead of scrolling a list of eleven thousand.
- Ask about your own numbers. "What is outstanding over sixty days?" answered from your data, not a manual.
- Write the reminder. A polite, specific chase for an overdue invoice, ready to send on WhatsApp.
Nothing is sent anywhere until you ask for it, and the platform runs on whichever model it has been configured with — including one hosted on your own server.
Who this actually suits
It fits a business that raises between a handful and a few hundred invoices a month and would rather not think about GST between the 10th and the 20th: traders, distributors, retail counters, workshops, agencies, consultants, contractors and manufacturers who sell on invoice.
It fits less well if you need deep manufacturing costing, multi-currency consolidation, or payroll — those are different products, and pretending otherwise wastes your evaluation time.
If you are not sure which side of that line you fall on, the free plan answers it in an afternoon at no cost. Start free now.
The price, plainly
Free is ₹0 and stays ₹0. The paid plans are bought for a fixed term, paid once, with no auto-renewal and no card kept on file — when a term ends the account drops back to Free until you decide to buy again.
There is no per-invoice charge, no per-user surprise on the free plan, and no feature that is technically included but practically throttled. What the plan says you get is what you get.
Compare the plans on the home page, or just start free now and look at the ceiling from the inside.
Where your data lives
On the server this platform is installed on. Every record carries a company identifier and every query is scoped to the signed-in account at the framework level, so one business cannot read another’s data by any route, including a crafted one.
Sign-in is rate limited, sessions can be restricted to one device per user, and passwords are stored hashed. Exports are available on every plan, free included: if you ever want to leave, your data leaves with you.
Frequently asked questions
Who generates it — supplier, buyer or transporter?
Any of them, depending on the arrangement. The registered person causing the movement is normally responsible, and a transporter can generate it where the supplier has not.
What happens if it expires in transit?
The goods are treated as moving without a valid e-way bill, with detention and penalty consequences. Extension is permitted within a window around expiry, so watch the clock rather than discovering it at a checkpoint.
Can I change the vehicle number after generating?
Yes — Part B can be updated when the vehicle changes, which is expected on multi-leg journeys.
Is my data shared with anyone?
No. It sits in this installation, scoped to your company. AI requests only happen when you explicitly ask for one, and nothing is sent anywhere otherwise.
Is it really free?
Yes. The Free plan is ₹0, needs no card and has no expiry. It has volume limits and leaves out the paid conveniences — watermark-free PDFs, GST return exports, the AI features, extra logins — but the invoices it produces are real GST invoices, and you can export your data from it whenever you like.
See it working on your own bills
The fastest way to judge billing software is to bill with it. Photograph one supplier invoice, raise one sales invoice, and look at the PDF your customer would receive.
