Add a customer and a contact
The difference between a customer and a contact, and why getting it right early saves work later.
IDup separates the customer — the company or household you do business with — from the contacts — the people at it. Invoices, projects and contracts belong to the customer; logins, e-mails and app invitations belong to the contacts.
Getting that right at the start is what lets a colleague take over a relationship without asking you anything.
Step by step
- Open Customers and create a new one. Fill in the legal name, the address, the currency and the tax details — invoices inherit all of these.
- Add at least one contact: name, e-mail, phone. That contact can be given portal access.
- Set the contact's role if you use roles — for example billing versus technical — so the right person gets the right e-mail.
- Tick Invite to the IDup app on the contact if you want chat, appointments and push with them.
- Assign the customer to a group if you segment your base; groups drive filters, reports and campaigns later.
- Save. The customer record now gathers everything: invoices, estimates, projects, tickets, files, notes and conversations.
In the app
- Open customers in the app.
- Create or open a customer and work with the same fields.
- The last loaded customer list stays readable offline, marked Offline, as of <time>.
Two customers that are the same company
It happens. Use the customer merge tool rather than deleting one: merging moves the invoices, projects and history across instead of losing them.
