Tenbin と Calendly：マルチアカウント向けにはどちら？
要点
Calendly はメール単位でアカウントが分かれやすい。複数の Google アカウントで別会社を運用する場合、Calendly も複数になりがちで空きが分断される。Tenbin は最大10アカウントをひとつのダッシュボードで Free/Busy 集約する。
| Feature | Tenbin | Calendly |
|---|---|---|
| Google accounts model | Up to 10 in one product | One primary account per subscription; multi-account is fragmented |
| Availability source | Free/busy across connected accounts | Calendar sources under one Calendly user |
| Best for | Multi-company Google identities | Single-identity scheduling with rich integrations |
Where Calendly falls short for multi-account users
Calendly is excellent for a single primary calendar. You can add multiple calendar sources to one account, but they are scoped to that Calendly user's email identity. Professionals who maintain separate Google Workspace accounts for different clients often end up with separate Calendly subscriptions, separate booking links, and manual coordination to avoid double-bookings.
How Tenbin solves this
Tenbin is built around OAuth connections to multiple Google accounts. Availability is computed from free/busy across all connected accounts simultaneously, then exposed through one booking page. You stay in one product, one link, one source of truth.
Pricing comparison
Tenbin's base plan is $10/month including two Google accounts, with +$3 per additional account up to 10. Calendly's paid tiers start around $12/user/month for individuals. For multi-account use, multiple Calendly seats multiply cost; Tenbin scales by account connection instead.
Who should use what
Choose Calendly when one Google (or Microsoft) identity is enough and you want deep ecosystem integrations. Choose Tenbin when you truly operate across several Google accounts and need one merged availability view without syncing event data between tenants.
The verdict
If your bottleneck is 'many Google accounts, one public schedule,' Tenbin is purpose-built. If your bottleneck is inbound routing for a single company mailbox, Calendly remains a strong default.
FAQ
Calendly can connect several calendar sources per user, but each Calendly account is centered on one user identity. Separate Google accounts for separate companies usually mean separate Calendly accounts and fragmented booking URLs.
