Onam season billing and stock checklist for kerala retailers and wholesalers

Onam is the largest purchasing festival in Kerala, which drives traffic to supermarkets and grocery stores, jewellery shops, electronics dealers, home furnishing retailers, bakeries and wholesale supplies. Customers are buying gold jewellery, traditional dress materials, home appliances, festive items, flowers, and hampers – making it one of the busiest selling seasons for retailers.

With increased sales come challenges, and some businesses face billing errors, GST issues, inventory discrepancies, stock-out scenarios, and slow billing counters during the Onam season. A wrong entry during a busy time may also result in sales losses, billing disputes, and customer complaints.

Preparing your billing software and inventory ahead of time can help generate higher sales and profits for your retail business in Kerala. You can use the Onam season billing and stocks checklist for Kerala below to prepare for the largest purchasing festival in Kerala.

Onam sales checklist to prepare your business

The first step in preparing for a busy sales season like Onam is to review inventory. You need to review inventory. You need to analyse your previous sales data and determine what to stock more of during the holiday. Always stock more seasonal products ahead of demand.

You should also do a stock audit and update your billing software. Ensure that the inventory in your billing software is up-to-date and accurate. Where possible, verify the physical stock count with what is in the billing software. Additionally, ensure that products close to expiry are marked down.

After identifying what to stock more of and pricing strategies for festive sales, update your billing software.

Check and update your billing software beforehand

Honestly, a hectic sales season is not really the right moment to find out you have got software issues. You should update and trial your billing software well before a heavy sales season period. Also, make sure you’ve got a stable internet connection if you’re on a cloud-based billing application, because it can be pretty annoying if it keeps dropping.

Anyway, you shouldn’t wait until the last week for updates either. Do the software upgrades ahead to time, so you don’t run into errors when things get busy. And right before Onam, test the receipt printers and the barcode scanners too, just to confirm they’re working properly- no surprises, nothing weird.

Ensure accurate GST calculation

All invoices generated during the onam must have accurate GST calculations. It is always important to double-check the GST calculations, especially when selling products in combo offers. Tax invoices should also include the correct GSTIN, invoice numbers, HSN or SAC codes where applicable, taxable value, tax amount and customer details where necessary.

Proper GST documentation during the Onam season will make it easier to file GST returns once the festive season is over and ensure compliance with tax regulations.

Enable barcode billing to speed up sales counters

Barcode billing is essential during busy seasons like Onam. Using a POS terminal or billing software with barcode scanning functionality will save you time manually searching for products. This feature also minimises billing errors since you only need to scan the barcode to generate invoices.

This feature is especially important in supermarkets, departmental stores, pharmacies, textile shops, and other retail establishments during the Onam season.

Monitor fast moving products and update inventory

Some products always sell faster than otters, especially during festive seasons like Onam. It is always important to monitor and update inventory on a daily basis instead of waiting until the end of the festive season. For wholesale suppliers, monitoring inventory can also help you determine which retail stores need more restocking during the festive season.

Talking about negative stock is another excellent way to ensure there are no stock outs of popular products during the Onam season. You should always enable the block negative stock feature in your filling software and ensure that invoices are not generated beyond available stock levels.

Enabling this feature in your billing software will also help you avoid inventory theft. It will also be important to update purchase records in your billing software as soon as possible after recording a purchase.

Doing this will ensure that your inventory is always accurate, thus helping you make informed purchasing decisions during the Onam season.

Take backups of all business data

During the onam season, businesses can generate hundreds or even thousands of invoices every day.It is, therefore, important to take backups of all data to ensure that valuable sales information is not deleted or lost due to technical difficulties.

Most cloud based billing applications take automatic backups of all data on a regular basis. Offline billing software requires you to take manual backups of data more often, especially problems occurring during the onam season.

Train your employees ahead of time

Most businesses always hire temporary staff to help with the the additional workload during the Onam season. It will be essential to train your staff on how to use billing software and other aspects of retail management before the festive season begins.

Your employees should also understand how to generate GST invoices and respond to customer queries during the Onam rush. Additionally, well-trained employees can also help speed up the billing process, thus avoiding slow billing counters.

Conclusion

Onam is one of the best times to boost sales for most businesses in Kerala. At the same time, it is also one of the busiest periods in terms of customer traffic, which invariably means higher sales revenue for businesses that are able to satisfy demand. However, increased customer traffic also comes with its own challenges.
