[ Contact ](https://nuxbe.com/en/contact) Common ChallengesProblems You Know All Too Well ------------------------------ ### Client Data Is Scattered Everywhere Contact details in one tool, communication history in another, and invoices in a third — finding a complete client picture takes too long. ### Scheduling Conflicts and Double Bookings Without real-time availability checks, double bookings frustrate clients and cost you revenue. Manual calendar management doesn't scale. ### Recurring Invoices Are a Time Sink Creating and sending the same invoices every month manually is tedious, error-prone, and takes time away from serving your clients. ### What was agreed sits in one person's mailbox The agreement is in an email only one colleague received. If they are away, the conversation with the customer starts over, and the customer notices immediately. How Flux HelpsYour Solution, Built In ----------------------- ### Complete Client Hub All client data, communication history, and documents in one place. See the full picture at a glance and never lose context again. ### Smart Scheduling with Availability Checks Book appointments with real-time availability. Let clients self-book through the customer portal — no phone tag, no double bookings. ### Automated Recurring Billing Set up recurring invoices once and let them run. Automatic generation, delivery, and payment tracking — hands-free revenue management. How it runsHow a service runs through the system ------------------------------------- 1. 1### The client and everything attached to them Contact, people, addresses, documents and the entire history hang on one record. Custom fields cover what your field needs on top, without it turning into a side list in a spreadsheet. [ Go to CRM ](https://nuxbe.com/en/modules/crm) 2. 2### Appointments and capacity in one place Client meetings, site visits and internal reviews sit in the shared calendar, invitations and reminders included. Who is available when can be read off before a date is promised. [ Go to Calendar ](https://nuxbe.com/en/modules/calendar) 3. 3### Quote, order, invoice The quote becomes the order and the order becomes the invoice, with no positions entered again. Recurring services are billed on a fixed rhythm instead of being written by hand every month. [ Go to Order Management ](https://nuxbe.com/en/modules/orders) 4. 4### Requests become records What a client reports becomes a ticket with a priority, an owner and a deadline. That makes a commitment checkable, and nothing depends on somebody remembering it. [ Go to Ticket System ](https://nuxbe.com/en/modules/tickets) 5. 5### Mail becomes part of the file The mailbox lives in the system and files incoming messages against the matching contact and record. Templates keep recurring replies looking the same whoever writes them. [ Go to Email Client ](https://nuxbe.com/en/modules/email) 6. 6### The client sees their own position In the portal a client finds their documents, the state of their requests and whatever has been released to them. That replaces the email with the attachment that gets asked for again three weeks later. [ Go to Customer Portal ](https://nuxbe.com/en/modules/portal) Key ModulesThe Tools You Need ------------------ [ #### CRM Central contact and address management for all your business relationships ](https://nuxbe.com/en/modules/crm) [ #### Calendar Unified calendar view for all your business events ](https://nuxbe.com/en/modules/calendar) [ #### Order Management Complete workflow from quote to invoice - all your sales documents in one system ](https://nuxbe.com/en/modules/orders) [ #### Ticket System Professional helpdesk with customer portal access ](https://nuxbe.com/en/modules/tickets) [ #### Email Client Integrated email management with intelligent automation ](https://nuxbe.com/en/modules/email) [ #### Customer Portal Give your customers 24/7 access to their data and documents ](https://nuxbe.com/en/modules/portal) LimitsWhere the limits are -------------------- Services is a broad field. What this page describes applies to businesses that advise, look after clients and bill recurringly. A profession with its own specialist software and legally prescribed procedures, tax advice or care work for instance, still needs that specialist software. Time recording and project billing are part of the standard scope; resource planning across months with a utilisation forecast per employee is not. Anyone who steers their business by utilisation should check this point before deciding. The customer portal shows what you release. A portal with its own look, its own forms and its own workflows is possible, but that is a project rather than a setting.
