Question 1

Do I need a certification to start a computer repair business?

Accepted Answer

No — most places don't legally require one to open a computer repair business, though local business licensing rules still apply and vary by state and city. A credential like CompTIA A+ isn't mandatory, but it builds customer trust and can help you win small-business or managed-service contracts where clients expect a recognized baseline qualification.

Question 2

Can I run a computer repair business from home?

Accepted Answer

Yes, many computer repair businesses start home-based to keep costs low. Check your local zoning rules and any HOA restrictions first, since some residential areas limit running a business from home, and get general liability insurance. Keep business equipment and customer devices separate from personal use, and lean on a strong Google Business Profile and online reviews to offset the less "storefront" first impression.

Question 3

What software do I need to run a computer repair shop?

Accepted Answer

At minimum, a system for repair tickets, parts inventory, and customer communication — a notebook and spreadsheet stop scaling past a handful of weekly jobs. BytePhase, for example, is trusted by 2,000+ repair businesses in 32+ countries and covers ticket management, barcode inventory, estimates-to-invoices, and automatic WhatsApp/SMS/email updates, with a 15-day free trial and no credit card required.

Question 4

What is the HSN code for mobile phones?

Accepted Answer

Mobile phones — smartphones and feature phones — fall under HSN heading 8517, which currently attracts 18% GST. This applies if your shop also sells handsets, not just repairs them. GST rates are set by Council notification, so always confirm the current rate on the official GST portal (gst.gov.in) before filing.

Question 5

What is the SAC code for mobile phone repairing services?

Accepted Answer

Repair and maintenance labour for mobile phones — screen replacement, battery swaps, software fixes and similar work — generally falls under SAC heading 9987 ("maintenance, repair and installation services"), typically taxed at 18%. Confirm the exact sub-code with your CA if your shop's service mix is unusual.

Question 6

What GST rate applies when I bill a repair job that includes both parts and labour?

Accepted Answer

Most mobile repair jobs are treated as a composite supply, taxed at the rate of the principal service (repair, typically 18%) — and since parts also usually sit at 18%, the practical rate rarely changes whether you bill one combined line or itemize parts and labour separately. Bundled accessories or extended warranties are edge cases worth a quick check with your CA.

Question 7

Do small mobile repair shops need GST registration?

Accepted Answer

Under general GST rules, service-led businesses typically need to register once turnover crosses ₹20 lakh (₹10 lakh in special category states), while predominantly goods-based businesses register at ₹40 lakh in most states — a repair-and-parts shop usually falls under the services threshold. These limits are set by notification and can change, so verify the current threshold on the GST portal before assuming you're under or over it.

Question 8

How do I show HSN and SAC codes correctly on my repair invoice?

Accepted Answer

Tag each parts line with its HSN code and each labour/service line with SAC 9987 (or the correct sub-code) so your invoice matches what you report in your GSTR-1 HSN summary. Repair-shop billing software like BytePhase lets you set the code once per inventory item and job-sheet line, so every estimate and invoice generated from a repair ticket carries the right code automatically instead of relying on someone retyping it correctly every time.

Question 9

How much does it cost to start a phone repair business?

Accepted Answer

Starting costs typically run $5,000-$15,000 for a home-based or mail-in setup, and $20,000-$60,000+ for a storefront, covering licenses, tools, an initial parts inventory, repair-management software, and a few months of working capital. Location is the biggest swing factor — rent and buildout for a storefront dwarf every other line item on the list.

Question 10

Is a phone repair business profitable?

Accepted Answer

Yes, when parts and labor are priced with a healthy margin and turnaround time stays fast. Independent shops commonly see 40-60% gross margin on screen and battery repairs, with board-level and water-damage work pricing higher still. Profitability comes down to a high first-time fix rate, controlled parts cost, and a growing repeat-customer base rather than one-off walk-ins alone.
