How Sift's credit wallet works, buying top-up packs, and automatic recharge
Credits, Top-ups & Auto-Recharge
Every Sift plan includes a monthly credit wallet shared across all channels. When you run low you can buy a one-off top-up pack, or enable auto-recharge to top up automatically before the balance runs out.
How Credits Are Spent
All channels draw from the same wallet at different rates:
| Action | Credits |
|---|---|
| 1 web-chat AI message | 1 credit |
| 1 email (conversation or notification) | 2 credits |
| 1 SMS | 20 credits |
Lead qualification is unlimited — credits only meter AI messages. Each plan's monthly allowance:
| Plan | Included credits/month |
|---|---|
| Starter | 5,000 |
| Growth | 15,000 |
| Scale | 45,000 |
Top-up Packs
Buy extra credits any time, on any plan. Top-ups are added to your wallet for the current period.
| Pack | Price | Per credit |
|---|---|---|
| 1,000 credits | £15 | £0.015 |
| 5,000 credits | £75 | £0.015 |
Tip
If you regularly need top-ups, upgrading to the next plan tier is more cost-effective than buying packs month after month.
Auto-Recharge
Auto-recharge automatically purchases a top-up pack when your credit balance drops below a threshold — so your agent never stops responding to leads mid-conversation.
How It Works
- You enable auto-recharge in Billing
- When your balance drops below the threshold, Sift purchases a top-up pack via Stripe
- The conversation continues without interruption
- You receive an email receipt from Stripe
Enabling Auto-Recharge
Click Billing in the sidebar.
In the usage area, find the Auto-Recharge toggle.
Toggle it on. The default threshold triggers when your balance is close to empty.
Tip
Auto-recharge is recommended for agencies with active SMS channels — SMS spends 20 credits per message, so balances move faster and you don't want leads to wait during business hours.
What Happens When You Run Out
If auto-recharge is not enabled and your credit balance reaches zero:
- The agent pauses sending new AI messages until your allowance resets or you buy a top-up
- Inbound enquiries continue to be received
- Your balance resets on the 1st of next month
