For business
How do you add iMessage to a SaaS product?
Put your own send interface between your features and the provider, model phone lines as a resource with a lifecycle, enforce consent and pacing at your layer rather than the tenant's, and price the line as a named add-on. Per-line billing against per-seat revenue is the trap that catches most teams.
The cost structure fights your pricing
| Model | Your cost at 100 tenants | The problem |
|---|---|---|
| A line per tenant | ~$10,000/month | Fixed cost per tenant regardless of usage |
| Shared pool | Much lower | Tenants share a number — usually unacceptable |
| Line as a paid add-on | Passed through | The honest model; price it explicitly |
The trap
Including iMessage in a flat per-seat plan. Your revenue is per seat and your cost is per line, so a tenant with two seats and three locations is immediately unprofitable — and you cannot fix it without repricing existing customers. Make the line a named add-on from day one, even if the margin is thin.
Four things that differ from a single-business integration
- Consent is your tenant's and your liability. If a tenant uploads a purchased list, the complaints and the flagged lines arrive at your platform.
- Number lifecycle becomes a subsystem — provisioning, release on churn, replacement when flagged, and an honest answer about portability.
- Support inherits a channel you do not control. Build per-tenant delivered-rate visibility before you launch, or every ticket is an investigation.
- Rate-limit per tenant, aggressively at first. One tenant's blast should not degrade another's line.
Ask providers about programmatic provisioning early
Several still allocate lines by hand, which is fine for one business and fatal for a product. The full SaaS guide.
Product plus API
| Provider | The product | The API |
|---|---|---|
| Miss Blue | Shared team inbox — the actual product | REST, behind a sign-in |
| Tuco AI | CRM-native, configured for you | Available; most deployments use native triggers |
| Sendblue | Light interface | API-first, public docs |
| Blooio | Light interface | API-first, OpenAPI spec |
| Linq | Enterprise platform | REST plus webhooks |
If you are embedding it in your own product
The requirements that actually matter
- Programmatic line provisioning — you cannot open a ticket per signup.
- Per-line webhooks and metrics, for support and billing attribution.
- Documented rate limits in numbers, because you are enforcing them on tenants.
- Volume pricing — at a hundred lines, list price is a negotiation.
- A sandbox, so CI has a target that is not production.
- SMS fallback, because your tenants' contacts are not all on iPhone.
Ask about provisioning first
It is the requirement most likely to be missing and the most expensive to discover late. Several providers still allocate lines by hand. The full SaaS guide.
