Practical guide
The best all-in-one booking and CRM app for a small business: what to look for.
The best all-in-one booking and CRM app is the one that covers the jobs you repeat every day without making you copy data between tools: online booking, a client record, reminders, messaging, payments and stock. Nexis Business OS combines online booking, a bio site, a client CRM, a WhatsApp team inbox with an AI assistant, an online store, stock and checkout, café menu and orders, online payments and finance. Starter is $49.99 a month and Pro is $149.99 a month, with a 7-day free trial of full Pro and no payment at signup.
7-day free trial of the full Pro plan with 150 free AI tokens. After the trial, choose Starter at $49.99 USD/month (200 AI tokens a month) or Pro at $149.99 (750 AI tokens a month).
Is this the right workflow for you?
No single app is best for every business, so this page gives you a checklist rather than a ranking. Nexis Business OS suits small and medium service businesses such as salons, barbers, cafés, clinics and studios. Test any tool, including this one, with one real week of work.
Follow the setup and decision checklist
- 01Check that booking and the client record are one thing
A booking should create or update a client record automatically, with history, notes and the next task. If you must retype the client, it is not really all-in-one.
- 02Check reminders and messaging
Look for automatic confirmations and reminders and a shared inbox for the channel your clients use. In Nexis Business OS that is WhatsApp, connected by QR code.
- 03Check payments and stock
You want online payments paid to your own account and stock that updates when you sell. Nexis supports Stripe, PayPal, CloudPayments, YooKassa and Freedom Pay, and its warehouse deducts stock automatically.
- 04Compare total monthly cost
Add up every subscription you would replace plus fees. Compare that with one plan price.
- 05Run a one-week trial
Set up your real services, make a test booking, connect messaging and take a test payment before you commit.
Test the complete journey
See what your team receives after the customer acts.
Use a sample enquiry or appointment in your workspace. Check the customer record, internal schedule and next task. Verify external messages and CRM transfers in the connected service itself.
A proposed workflow change
An operational example to evaluate in your trial, not a customer case study or a promise of results.
Without a connected process
Booking in one app, client notes in another, chats on a phone and payments somewhere else.
With the Nexis Business OS workflow
One workspace where a booking, the client, the conversation, the payment and the stock movement are connected.
Check before you launch
- Make a test booking and confirm the client record appears.
- Test a reminder to your own phone.
- Test one payment end to end.
- Check the plan covers your team size.
