When Sri Lankan shop owners compare POS prices, they often compare a monthly fee against a one-time licence and pick the smaller number. That comparison is misleading. The honest way is to add up what you will actually pay over three years, including everything the headline price leaves out.
The Two Pricing Models
Monthly subscription. You pay a fixed amount each month. Setup, updates, backups and support are normally bundled in. Invenova’s retail plans are an example: Starter is Rs. 3,500/month, Professional Rs. 5,500 and Business Rs. 7,500. Restaurant plans are Rs. 5,500, Rs. 7,500 and Rs. 9,500. Every plan includes free installation, setup and staff training. Current details are on the pricing page.
One-time licence. You pay a larger amount up front and own the software. Support, updates and sometimes hosting are then charged separately, often as an annual fee.
A 3-Year Worked Example
The one-time figures below are illustrative only, chosen to show the method. They are not a quote from any vendor. Replace them with the real numbers from each quote you receive.
| Cost item | Monthly plan (Professional) | One-time licence (example) |
|---|---|---|
| Up-front licence | Rs. 0 | Rs. 150,000 |
| Subscription / annual support | Rs. 5,500 × 36 = Rs. 198,000 | Rs. 25,000 × 3 = Rs. 75,000 |
| Installation and training | Included | Often extra: ask |
| Updates | Included | Often extra: ask |
| Backups | Included (online) | Your responsibility |
| 3-year total (before extras) | Rs. 198,000 | Rs. 225,000 + extras |
Over the same period, the Starter plan (Rs. 3,500 × 36) comes to Rs. 126,000 and the Business plan (Rs. 7,500 × 36) to Rs. 270,000. The point is not that one model always wins. It is that the licence only looks cheaper until you add support, updates and anything it excludes.
Costs That Hide Outside the Headline Price
Ask each vendor, in writing, about every one of these:
- Installation and setup: free, or a separate fee?
- Staff training: included, or charged per session or per branch?
- Updates: automatic and free, or paid upgrades?
- Support: included, or a yearly contract? What are the hours?
- Extra counters: priced per terminal? Invenova’s Starter plan covers 1 terminal, Professional up to 3 and Business is unlimited.
- SMS messages: how many are included? Invenova includes 100 a month on Starter, 500 on Professional and unlimited on Business.
- Branches: does a second shop cost extra?
- Data export: can you take your data with you if you leave?
- Hardware: is it required, or does the software work with the printers and scanners you already own?
When a One-Time Licence Can Make Sense
- You have one counter, stable power and a technical person who will handle backups.
- Your internet is unreliable and you need a system that runs without it.
- You are certain you will use the same system for many years with few changes.
When a Subscription Usually Wins
- You want predictable monthly costs and no big up-front spend while you are still growing.
- You want updates, backups and support without a separate contract.
- You may add counters or branches. See multi-branch inventory management.
- You want to be able to switch if the service disappoints, with less money at stake.
What to Do Next
- Get written quotes from two or three providers, listing every cost above.
- Put the numbers into a table like the one here, over three years.
- Add what you would otherwise spend on backups, IT help and training.
