Free up to US$20 a month.
Beyond that, you pay the month's consumption, at a transparent price. No per-seat charge on the usage model, no surprises.
How billing works
The software is free: we never charge for it, there is no per-seat charge on the usage model, and every feature is included from the start. What has a real cost is the infrastructure that keeps Sellio online 24/7, so that is the only thing we bill.
Every account starts with a free spending cap: US$20 of usage per month. Most companies stay within it and pay nothing. That free cap is the way in, not a permanent discount: once you add a card and raise the limit, the month's usage is billed from the first cent, at a transparent price, itemized on your invoice.
The model, no fine print
Free forever
We never charge for the software. The product is 100% ours and you use it for free, with no monthly fee.
Everything unlocked on the usage model
On the usage model, everyone gets access to everything: no feature locked away waiting for you to pay. Per-seat editions exist only as an option, for those who prefer bundles.
Pay only for what you use
A month that stays within US$20 of usage costs nothing. Beyond that, you pay the month's consumption: infrastructure only, nothing more.
$20/month free to start
Every account opens with a free monthly spending cap. Most companies start and keep going without paying anything; raise the limit and usage is billed from the first cent.
No catch
Every cent shows up on your invoice, line by line.
What runs behind it
Running Sellio has a real infrastructure cost. We break down every item and show why it is far cheaper than paying for licenses.

This is roughly what companies like yours pay per month, only for the infrastructure they actually use.
| Profile | Typical usage | Est./month |
|---|---|---|
| Startup | 3 users, light usage | $0free (under $20) |
| Small business | ~10 users, moderate volume | ≈ $64 |
| Mid-size | ~40 users, high volume | ≈ $423 |
| Large / dedicated | ~150 users, dedicated infra | ≈ $2,693 |
Up to $20/mo of usage is free while you stay on the starter limit, with no card. Once you raise the limit, you pay the month's usage from the first cent: only the infrastructure you use, never a monthly fee.
