Optical Shop Billing, VAT and Warranty Checklist for Nepal

Updated 14 Oct 2026 ยท 7 min read ยท WebsNP team

Most counter disputes in an optical shop are about money and promises: the advance, the balance, a remake, a repair under warranty. They are avoidable with a few written rules and consistent records. This checklist covers billing, VAT and warranty practices for Nepali optical shops. It is about record keeping, not legal or tax advice, so confirm tax duties with the Inland Revenue Department or your accountant.

Itemise the bill

A bill should show the frame with its model, the lenses with type and coating, any other items such as a case or solution, discounts, the total, the advance paid, the balance and the delivery date. A customer who can read each line is a customer who does not argue later. Print the shop name, address and phone number, and if you are VAT registered, your PAN or VAT number as required.

VAT basics for your records

The standard VAT rate is 13%. Whether you must register and how it applies to your goods is a question for the IRD and your accountant. For your own books, make sure each sale is numbered, the VAT is calculated consistently and purchase bills from suppliers are kept in order. Imported frames and lenses often arrive with customs paperwork, so file those papers with the purchase record. A clean sales and purchase list makes the end of the Nepali fiscal year, which begins in Shrawan, much easier.

Advance and balance rules

  • Decide a minimum advance for custom orders and apply it to everyone.
  • Record every payment with the date and the staff member who received it.
  • Write the rule on the receipt: for example, how long an unclaimed order is held.
  • Check the pending balance list weekly and message customers politely.

Unclaimed orders tie up money and shelf space. A clear holding period, communicated at the time of sale, helps you act without argument.

Remake rules

Decide who pays when an order is remade: the lab, the shop or the customer. A lab error is the lab's cost, a change of mind is usually the customer's, and a test change may be shared. Whatever your policy, record the reason for each remake. It tells you whether the problem is in the lab, the counter or the test.

Warranty and repair records

If you offer a warranty on frames or lenses, define exactly what it covers, for how long and what it excludes. Print the terms on the receipt. When a customer returns, search the original order, check the date and record the repair, replacement or refusal with a reason. Without this, you end up deciding case by case, which feels unfair to everyone.

Discounts and festivals

Festival offers drive volume but also confuse the books. Record each discount with a reason such as Dashain offer, staff or regular customer. After the festival, check how much you gave away and whether the extra sales justified it.

Stock mistakes that hit the bill

Selling a frame that is not in stock, or at an old price, causes awkward corrections. Keep selling prices updated whenever purchase costs change, and count stock regularly. Barcode labels reduce the chance of a wrong frame being billed.

The weekly checklist

  1. Review pending balances and overdue orders.
  2. Check discounts above your normal limit.
  3. Count one section of frames and fix differences.
  4. File supplier bills and customs papers.
  5. Back up your records.

A short walkthrough with a generic example

Take an example order. A customer chooses a frame and lenses, pays an advance and is promised glasses in a week. The counter makes one bill showing the frame, the lenses, the advance and the balance, and prints the warranty terms on the receipt. The job slip goes to the lab with the order number. When the glasses return, they are checked, the customer is messaged and the balance is collected on delivery. Two months later the customer comes back with a loose arm. Staff open the original order, see that the warranty period has not ended, record a free adjustment and close the case. Every step was visible and fair, and nobody had to remember or argue.

If your shop would struggle to follow the same steps today, pick the weakest step and fix it first.
