[ Contact ](https://nuxbe.com/en/contact) What Nuxbe does for service businesses -------------------------------------- Nuxbe runs a service business from the first contact to the paid invoice in one system. The client is a contact with any number of addresses, and orders, invoices, tickets, projects and emails hang on it. Whoever takes over a client reads their history in one place instead of asking colleagues. Ongoing services such as support contracts or memberships are kept as subscription orders with a notice period and a minimum term. A scheduled run creates the invoice, prints it and sends it by email. Individual orders come from the quote without any lines being entered again. Requests by email become tickets, and the time spent on them is recorded on the ticket and marked as billable. That time can be carried into orders, so hours worked end up on the invoice and not in a spreadsheet next to it. Common Challenges Problems You Know All Too Well ------------------------------ ### Client Data Is Scattered Everywhere Contact details in one tool, communication history in another and invoices in a third. Putting together a complete client picture takes too long. ### Who is free when sits in five calendars Everyone keeps their own calendar, and whether a colleague is free on Thursday only comes out when somebody asks. A commitment to the client turns into guesswork. ### 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 Helps Your 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. ### One calendar the whole team sees Public calendars are visible to every user, and tasks, projects, working hours and resource bookings can be shown alongside. Who is already booked is visible before a date is promised. ### Automated Recurring Billing Recurring services run as subscription orders. A scheduled run creates the invoice, prints it and sends it by email, and if a payment does not arrive, payment reminders take over. How it runs How a service runs through the system ------------------------------------- 1. 1 ### The client and everything attached to them Contact, addresses, documents and the entire history hang on one record. Payment terms, price list and credit limit sit on the contact and carry into every new order without anyone entering them again. [ 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 public calendars the whole team sees, as a series where needed. Who is booked 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 status, owners and a history of internal and public comments. The time a request takes is recorded on the ticket and can be billed. [ 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.

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. Frequently asked questions -------------------------- Can I bill recurring services automatically? Yes, through subscription orders. A scheduled run creates the invoice, prints it and sends it by email. Notice period and minimum term can be set, and cancellation takes effect immediately or at the end of the current period. Can consulting and support time be billed? Yes. Time is recorded on the ticket, can be marked as billable and carried into orders. The time worked becomes a line on the invoice. Can the team see who is booked when? Yes. Public calendars are visible to every user, and tasks, projects, working hours and resource bookings can be shown alongside. With the CalDAV package, appointments also appear in Apple Calendar, Thunderbird and Outlook, or as an ICS feed in Google Calendar. Are client emails filed against the right client? Yes. Nuxbe fetches mailboxes over IMAP and files incoming mail against the contact by sender address, and against the order when an order or invoice number is in the subject. A folder for requests can turn every new message into a ticket. Does Nuxbe replace the specialist software of a tax firm or a care service? No. Professions with their own specialist software and legally prescribed procedures still need it. Nuxbe takes care of what happens alongside: clients, appointments, orders, tickets and invoices.
