Sollabs Tech Bill Explained: How to Read Your Tax Invoice and Official Seal (With Sample)
Sample Sollabs Tech bill
What each part of the bill means
1. Business details
The top of every bill shows Sollabs Tech, our address (SS Colony, Bharathiyar 4th Street, Madurai, Tamil Nadu 625402), phone +91 90038 50743 and email sollabstech@gmail.com.
2. Invoice number and date
Each bill is a tax invoice with a unique number in the format SLT-YYYYMMDD-HHMMSS: SLT, then the date and time the bill was made. The date is the most important line for you, because every warranty benefit is counted from it.
3. Bill to and payment
Your name and phone number, and how you paid (for example cash, UPI, card or bank transfer).
4. Your device
The product line identifies exactly what you bought:
- Type: laptop or mobile.
- Description: brand, model and key specs, plus the serial number for laptops or IMEI for phones.
- Condition: for example new, refurbished or used.
- Accessories: what came with it, such as the charger or box. Keep these for a refund.
5. Amount and GST
The taxable value, the GST split into CGST and SGST, and the grand total you paid, written in figures and in words.
6. Warranty and service promise
Every bill prints the after-sales promise: 7-day refund, 1-month exchange, 6-month upgrade offer and 1-year free service, plus what isn't covered.
7. Seal and signatures
A genuine bill carries the official Sollabs Tech seal and the authorised signature, with space for the customer's signature.
The official Sollabs Tech seal
Every genuine Sollabs Tech bill is stamped with this seal. Here's how to recognise it:
- A blue, circular stamp with a double outer ring.
- SOLLABSTECH curved around the top and MADURAI around the bottom.
- A star on each side.
- The Sollabs Tech “S” logo in the centre.
A bill without the seal and an authorised signature, or with a seal that looks different, may not be genuine. WhatsApp +91 90038 50743 with the invoice number and we'll confirm it.
