Set SMS, Email, and Phone Markup in Rebilling Settings
Stop eating usage costs. Set your markup once in Agency Rebilling and every sub-account is covered automatically.
Watch it on its own page, with the transcript.
Rebilling settings live under your agency's Settings > Rebilling. This is where you set a markup percentage on the usage-based costs HighLevel passes through to you, things like SMS segments, email sends, phone number rental, and AI usage. Once the markup is set, the system applies it to every sub-account automatically instead of you tracking usage in a spreadsheet.
Most agencies either eat these costs quietly or try to invoice them manually after the fact, which means margin leaks every month it gets skipped. Turning on rebilling means the markup is baked into what the client sees, so you are covered the moment usage happens instead of chasing it later.
The catch: rebilling is part of SaaS mode, so it only works if your agency has that configured and sub-accounts are set up to be billed through it. Before you flip on a new markup, check the wallet or prepay balance on a couple of active sub-accounts so nobody gets an unexpected charge on their next cycle.
How to use it
- Go to Settings > Rebilling in your agency view
- Set markup percentages for SMS, email, and phone numbers
- Confirm SaaS mode is active on the sub-accounts you want billed
- Check one sub-account's wallet balance before saving changes
- Review the rebilling report after the first billing cycle
Who it helps
Agency owners and SaaS resellers managing usage costs across multiple client sub-accounts.
