Pricing

Pay in credits. Nothing monthly.

Everything on Atomside is priced in credits. Buy a pack, and each letter takes its credits as it goes out. The quote shows the exact number before anything is charged.

How credits work

One balance for every action

Letters today. Signed-for post, courier and printed packs use the same credits when they arrive. No new account, no new bill.

Your agents cannot spend what is not there

Credits are prepaid, so the balance is a hard ceiling. Each key also has a daily and monthly budget in credits. When it is reached, work stops.

A credit always buys the same thing

Prices are fixed in credits. A bigger pack simply gives you more of them. Anything that fails goes back to your balance as credits.

Letter prices

Printing, envelope and postage included. Up to 5 sheets. Pounds exclude VAT.

Example

A 3-sheet colour letter, second class:

17 + 2 + 2 = 21 credits (£2.10)

Billing questions

What is a credit?

A prepaid unit worth 10p. Every action on Atomside has a fixed price in credits, and every quote, receipt and record shows credits with the pound figure beside them.

Why credits and not pounds?

So one prepaid balance covers every action we add, and so an agent has a hard limit it cannot go past.

Can I cap what an agent spends?

Yes. Set a daily and monthly budget in credits on each key.

Do credits expire?

12 months after your account was last used. Sending or buying resets the clock.

Can I get a refund on unused credits?

Yes, within 14 days of buying a pack, for any credits you have not spent.

Do you offer volume pricing?

Yes, if you send more than 2,000 letters a month. Email hello@atomside.com.
