SMS Credits Explained: How SMSFlow Billing Works

TL;DR: SMSFlow bills in credits, and some messages use more than one credit. New Australian business accounts get 50 free credits after signup and verification; buy more from Billing and check current rates on the pricing page.

How SMS credits work (quick guide)

1. A credit is the billing unit, not a guaranteed “one message = one credit” rule. Your balance drops by the credits each send needs.
2. Longer messages can use more than one credit. Segment length, encoding (for example emojis or some special characters), and content affect the credit count shown before you send.
3. New signups get 50 free credits once the account is set up for an Australian business (valid ABN, email verification, 2FA, and related checks). You cannot send until those steps are done.
4. Purchase more credits in Account → Billing. There you also see credits remaining, billing details, payment methods, and past invoices (view or download; invoices are not emailed automatically).
5. Check live rates on the pricing page rather than relying on old screenshots or third-party lists. Credit packs and costs can change, so SMSFlow pricing is the source of truth.

Why credits matter for bulk SMS in Australia

If you run reminders, order updates, or short promos, you need a clear link between message length and cost. Credits make that link visible in the send flow: you draft the text, pick contacts or groups, and see a credit counter for the message and the total before you confirm.

That preview helps you trim copy, drop unnecessary characters, or split a campaign when the total would burn through your balance faster than expected. It also keeps budgeting simple when several people on the team send from the same account.

SMSFlow is built for Australian businesses sending to Australian numbers. Eligibility and first send sit behind verification (ABN validated from the account area, verified email, 2FA to finish signup, and possible extra checks for non-business email domains). Credits only become useful after those gates are cleared.

Credits vs messages (what uses more than one)

Billing is per credit, not strictly per message. In practice:

• Short plain-text SMS often map to a single credit.
• Longer bodies split into multiple segments and use more credits.
• Some characters and emojis change encoding and can increase segment count.
• Placeholders such as {first_name}, {last_name}, or {stop_message} expand at send time; the preview reflects the filled length where possible.

Always trust the on-screen credit counter in Send SMS before you hit send or schedule. Scheduling uses the same credit model; you can cancel a scheduled message from scheduled reports if plans change (you cannot edit a scheduled message in place).

Getting started: free credits and first top-up

After you register as an Australian business and complete verification, your account includes 50 free credits. Use them to test templates, a small group send, or API smoke tests if you use developer keys.

When the balance runs low:

• Open Maintenance → Account → Billing (or the Billing area in account settings).
• Review credits remaining.
• Purchase credits and keep payment methods up to date.
• Open past invoices when you need records for bookkeeping.

For current pack options and rates, use the pricing page. We do not publish fixed dollar figures in guides because packs can change; the live page stays accurate.

Seeing spend without overcomplicating reports

You do not need a full finance suite inside SMS to stay honest about usage:

• Dashboard — pick a date range and review sent, delivered, failed, queued, received, opt-outs, and related counts.
• Reports → Sent — filter by status and date; useful when you want message-level context (no export and layouts are not customisable).
• Billing — balance, purchases, and invoice history.

Together, those views answer “how many messages went out?” and “how many credits did we buy?” without treating SMSFlow as a full CRM or accounting product.

Common pitfalls

• Assuming every SMS is one credit. Write the real message (including opt-out language where required) and read the credit counter.
• Buying credits before verification finishes. Sending stays blocked until email, ABN, and related checks pass.
• Ignoring Sender ID trade-offs. A Sender ID brands the outbound name, but recipients cannot reply when a Sender ID is used. Replies only apply when you send in a way that allows inbound; Inbox shows inbound from numbers you have messaged, and you reply via Send SMS, not from Inbox itself.
• Expecting automatic invoice emails. Invoices stay available to view and download in Billing.

FAQ

Do all SMS cost one credit?

No. SMSFlow bills per credit, and some messages use more than one credit depending on length and encoding. Check the credit counter before you send.

How many free credits do I get?

New signups receive 50 free credits after account setup. SMSFlow is for Australian businesses with a valid ABN and the usual verification steps before first send.

Where do I buy more credits?

In Account Billing you can purchase credits, manage payment methods, and see credits remaining. Compare packs on the pricing page.

Can I get invoices emailed automatically?

No. Past invoices are viewable and downloadable from Billing only.

Do scheduled messages use credits differently?

No. Scheduled sends use the same credit model as immediate sends. You can cancel scheduled messages from scheduled reports if you need to free capacity or change plans.

Is SMSFlow only for Australian businesses?

Yes. A validated ABN, Australian mobile, and verification (including 2FA and email checks) are part of how accounts are set up and allowed to send.

SMSFlow and credit-based sending

SMSFlow is a web platform (and API) for sending SMS to Australian numbers, managing contacts and groups, viewing Inbox replies from numbers you have messaged, and tracking activity on the dashboard and reports. Billing stays straightforward: credits remaining, top-ups, and invoices in one Billing area, with clear credit previews when you compose a send.

Conclusion

Credits are the unit that ties message length to cost. Learn the counter, use your 50 free credits after verification, top up in Billing, and confirm rates on pricing before large campaigns.
