FBR Digital Invoicing for Auto Workshops & Car Mechanics (2026)
Auto workshops and car mechanics in Pakistan: how FBR digital invoicing works for spare parts, repair labour, IRN and QR — in simple words.
Do auto workshops and mechanics need FBR digital invoicing?
In short: if your workshop is sales tax registered, the spare parts, oil, tyres and batteries you sell must go through FBR's Digital Invoicing system. Each bill then carries a special number and a QR code. Repair labour is treated a little differently — we explain both below in plain words.
FBR Digital Invoicing is Pakistan's real-time billing system (real-time means the bill is checked and saved by FBR the moment you make it). The rules come from SRO 1852(I)/2025, the notification FBR issued on 24 September 2025 that sets who must join and by when. Staying out after your date carries a penalty that starts at Rs 500,000.
Every bill you post for goods gets an IRN (Invoice Reference Number — the unique number FBR gives each invoice) and a QR code (the square barcode a buyer can scan to check the bill is real). No IRN means the bill is not valid for FBR. A very small workshop below the sales tax limit is not in yet; it joins after it registers or after FBR notifies its group.
Parts vs repair: the one rule that changes everything
A workshop does two kinds of business, and tax treats them differently. Selling goods — spare parts, engine oil, tyres, batteries, filters, accessories — is a federal matter, so it goes to FBR. Charging for repair or labour is a service, and in Pakistan services are taxed by your province, not by FBR.
That means the parts you sell go through FBR Digital Invoicing, while your repair and labour charges are reported to your provincial authority — the SRB in Sindh, PRA in Punjab, KPRA in Khyber Pakhtunkhwa, or BRA in Balochistan. Islamabad is the exception: there, FBR handles services too. Our guide 'FBR vs Provincial E-Invoicing (SRB, PRA, KPRA)' explains this split.
So if you sell parts and are registered for federal sales tax, you must issue FBR digital invoices for those goods. Your provincial authority may run its own e-invoicing for services, so check with them as well. Our guide 'Goods vs Services in FBR Digital Invoicing' walks through where a bill belongs.
What tax rate goes on parts and oil
Most spare parts, oil and accessories are taxed at the standard rate (the normal sales tax rate on ordinary goods). You add it on top of your selling price, and it shows as its own line on the bill. Rates change from time to time, so confirm today's exact figure with your tax adviser before you set prices.
One rule matters for costly items. A special reduced 5% rate cannot be used once the value of a single item is over Rs 20,000 — the normal rate applies instead. A pricey imported part or a full battery set can cross that line, so do not put the low rate by habit; it is a common reason a bill is rejected (FBR error 0079).
A few branded goods that carry a printed retail price — some lubricants and batteries do — are billed on that printed price under the Third Schedule (a special list where tax is worked out on the price printed on the pack, not on your selling price). If you sell such branded stock, check the list. Our guide 'Third Schedule Goods in FBR Invoicing' explains it in plain words.
Registered vs unregistered buyers — the field to get right
Workshops serve two very different buyers, and the bill is not the same for both. A walk-in car owner usually has no tax number — you mark that buyer as 'Unregistered'. A company, a rent-a-car fleet, or an insurance-paid repair has an NTN (National Tax Number — the 7-digit tax number), which you record on the bill.
Why it matters: a registered buyer with a proper invoice and IRN can claim back the tax it paid (input tax — the sales tax a registered business subtracts from what it owes). A walk-in owner cannot, and does not need to give any number. Choosing the wrong buyer type is a common reason a bill fails, so set this field with care.
When you sell to an unregistered buyer, an extra charge called further tax is usually added on top of the normal tax. The figure changes over time, so confirm the current one. Our guides 'Registered vs Unregistered Buyers on FBR Invoices' and 'Further Tax and Extra Tax in FBR Invoicing' cover both sides.
What goes on a workshop invoice
Bill the goods one line per item. On each parts line show the item name (for example: brake pads, 5-litre engine oil, 12V battery, tyre), the quantity, the unit of measure (UoM — how you count the item, such as pieces, litres or units), the rate, and the tax worked out on that line.
Each goods line also needs an HS code (Harmonised System code — an international product number FBR uses to name the item). Set the right HS code once per part and Digi Invoice reuses it. Keep your labour or service charge on its own line so it is clear which part of the bill is goods (for FBR) and which is service (for your province).
In FBR's test list, a normal counter sale of standard-rate goods is scenario SN001 for a registered buyer and SN002 for an unregistered one; a registered retailer selling to an end consumer uses SN026. You do not have to memorise these — the platform picks the right one from the buyer type and rate you choose.
Returns, warranty and fixing a wrong bill
Parts come back — a wrong fit, a faulty battery, a warranty swap. If a customer returns a part or you need to correct a bill after posting, you do not delete the invoice. FBR keeps every posted bill for the record.
Instead you raise a debit note or credit note against the original bill. Our guide 'Debit Note and Credit Note in FBR Invoicing' shows exactly how, and there is a fixed time window to do it, so act quickly rather than leaving it for month-end.
Durable goods like vehicles, appliances and their parts share these billing habits; if you also sell whole cars or bikes, our guide 'FBR Digital Invoicing for Car Dealers & Automobile' is a close match.
How Digi Invoice keeps it simple
You do not need to be a tax expert. Pick the part, choose whether the buyer is registered or unregistered, and Digi Invoice builds the line, works out the standard-rate tax and any further tax, and posts the bill to FBR's Digital Invoicing system. You get the IRN, the QR code and a clean printable invoice back in seconds.
Save your full parts and rate list once — every filter, oil grade, tyre size and battery — and bill in a few taps at the counter. On a busy day you can import many bills together instead of typing them one by one; our guide 'FBR Digital Invoicing Bulk Upload' shows how.
Every posted bill is saved in a built-in ledger, so at return time your record is already organised and audit-ready. Ready to start? Create a free account and post your first FBR-compliant parts invoice the same day.
Difficult words in this guide
IRN (Invoice Reference Number) — the unique number FBR gives your bill after you post it. No IRN means the bill is not valid for FBR.
QR code — the square barcode printed on the bill; anyone can scan it to check the invoice is real.
Standard rate — the normal sales tax rate charged on ordinary goods like most spare parts. Confirm today's figure, as rates change.
Further tax — an extra charge added when you sell to an unregistered buyer, on top of the normal tax.
Provincial service tax — the tax on services like repair labour, charged by your province: SRB in Sindh, PRA in Punjab, KPRA in KP, BRA in Balochistan. Islamabad is handled by FBR.
