TimeRex vs SailLab | A thorough comparison of features, pricing, and usability [2026 edition]

Two leading Japan-built scheduling tools compared head-to-head: pricing, features, and real-world usability.

"TimeRex or SailLab — which one should we pick?" When you shortlist Japan-built scheduling tools, this pair comes up often. TimeRex is the established choice for interview and sales-call scheduling; SailLab is a booking system that adds service menus and staff selection on top of scheduling. Their strengths are clearly divided.

This article compares both tools on features, pricing, and honest strengths and weaknesses, based on official information as of July 2026. The short answer: pick TimeRex if simple 1-on-1 scheduling is the core of your work, and SailLab if you need menu selection, staff designation, and prepayment in the booking flow.

What is TimeRex | A Japan-built scheduling tool with 600K+ registered users

TimeRex is a Japan-built scheduling tool from Mixtend Inc., the company behind Chouseisan. Its official site cites more than 600,000 registered users and adoption by major Japanese companies, making it one of the reference tools in the domestic scheduling category (as of July 2026).

• Calendar sync with Google Calendar and Outlook (Microsoft 365)
• Auto-generated meeting URLs for Zoom, Google Meet, and Microsoft Teams
• Reminder emails for confirmed meetings
• Multi-member team scheduling (priority-based auto-assignment on the Basic plan and above)
• A simple, no-frills UI that interview candidates navigate without friction

Its design philosophy is specialization: confirm an external meeting time in as few steps as possible. The deliberately narrow feature set keeps the learning curve short, which is why it is widely used for interviews, sales calls, and external meetings.

What is SailLab | A booking system with menu selection and staff designation

SailLab, by contrast, extends scheduling into full booking intake. On top of the scheduling basics — calendar sync, video links, reminders — it layers the features a booking business needs: paid menus, staff selection, and payment.

SailLab

SailLab is a Japan-built booking system that combines scheduling, booking pages, and prepayment in one tool. Launched in 2026, it is designed for businesses whose clients pick a menu and a staff member when they book — coaches, consultants, licensed professionals, and schools. Coaching businesses are a typical example.

• Service menus: offer options with different content, duration, and price — a 30-minute trial, a 60-minute session — on one booking page
• Staff designation: clients choose who they book with, and you can attach a designation fee
• Prepayment: Stripe integration completes card payment at booking, with automated refund policies and invoice billing for corporate clients
• Branding: a cover image and brand colors make the booking page look like yours
• The basics: Google and Outlook calendar sync, auto-generated Zoom/Meet/Teams links, and automated reminders are standard

Plan	Monthly	Key features
Free	¥0	1-on-1 bookings, 1 schedule link, calendar sync, reminders
Light	¥1,000 (¥800/mo billed annually, tax-excl.)	Unlimited links, cover-image branding, capacity-managed events, team management
Standard	¥1,500 (¥1,200/mo billed annually, tax-excl.)	Service menus, staff designation, Stripe payments, round robin, analytics

The platform fee on sales is 0% — only Stripe's standard processing fee applies (as of July 2026; details on the pricing page). It suits solo professionals and small teams who want scheduling and paid-session bookings handled by a single tool.

Pricing comparison

TimeRex pricing (as of July 2026)

• Free: ¥0 — core scheduling at no cost (limits such as 2 participants for multi-person coordination)
• Basic: ¥750/month billed annually, ¥900 billed monthly (tax-excl.)
• Premium: ¥1,250/month billed annually, ¥1,500 billed monthly (tax-excl.) — Salesforce/HubSpot integration, custom question fields, CSV export
• Enterprise: for 40+ users, custom pricing

SailLab pricing (as of July 2026)

• Free: ¥0 — 1-on-1 bookings, one schedule link, unlimited bookings
• Light: ¥1,000/month, or ¥800/month billed annually (tax-excl.) — unlimited links plus branding
• Standard: ¥1,500/month, or ¥1,200/month billed annually (tax-excl.) — menus, designation, and payments

For one user on annual billing, TimeRex Basic (¥750) and SailLab Light (¥800) sit at almost the same price. The difference is where the upper plans point: TimeRex Premium goes deeper into scheduling automation (CRM integration), while SailLab Standard goes toward booking-business features — payments, menus, and designation.

Strengths and weaknesses

TimeRex strengths

• Reassurance from 600K+ registered users and enterprise case studies
• A simple scheduling flow that is easy to send to candidates and clients
• A feature set well matched to interview coordination

TimeRex weaknesses

• No booking flow built around menu selection or staff designation
• No payment feature listed on its plan pages — collecting for paid sessions needs a separate tool
• Limited visual customization of the scheduling page

SailLab strengths

• Menu selection, staff designation, and prepayment complete on a single booking page
• Cover image and brand colors let you shape the page's first impression
• 0% platform fee on payments (only Stripe's standard fee)

SailLab weaknesses

• Launched in 2026, so its operating track record is still short
• No CRM integration yet (Salesforce and HubSpot are on the roadmap)
• Notifications are email-only — no SMS or LINE
• No SSO/SAML or other enterprise security requirements

Which should you pick: decision criteria by situation

Two axes decide it: who you coordinate with, and whether money changes hands.

TimeRex fits when — (1) external 1-on-1 scheduling (interviews, sales calls) is the core of your work; (2) no payment is involved in the booking; (3) you want to automate scheduling operations including CRM integration; (4) your organization weighs installed track record heavily.

SailLab fits when — (1) you are a coach, consultant, or licensed professional offering multiple service menus; (2) clients choose which staff member they book; (3) you want paid sessions charged at the moment of booking; (4) you want the booking page to carry your own brand.

If staff designation and multi-menu operations are your main concern, see our guide to booking systems with staff selection.

Migrating from TimeRex to SailLab

1. Create a free SailLab account and connect Google or Outlook calendar
2. Recreate your TimeRex scheduling pages as SailLab schedule links
3. If you have multiple menus or staff, set up service menus and staff profiles
4. Configure the cover image, brand colors, and reminder wording
5. Replace the booking URL in your email signature, business cards, and website
6. Let in-flight coordination finish in TimeRex; route new bookings to SailLab

Both tools have free plans, so a gradual migration with a period of parallel running is realistic.

Summary: decide by the shape of your bookings

TimeRex and SailLab sit in the same scheduling category but solve different problems. If the goal is confirming meeting times in the fewest steps, choose TimeRex; if bookings involve menus, staff designation, and payment, choose SailLab — the shape of your bookings is the fastest tiebreaker.
