Plans & billing

Choose and change your plan

IDup has four plan families — business, private, tax advisor and trustee — with three plans in each. This is what separates them.

The plan families exist because the four kinds of customer need different things. A freelancer is not a small trust company, and a private household is not either.

Inside a family, the three plans differ mainly in size: how many employees, how many customers and contacts, how much storage, and for the professional families how many tax clients or mandates you may manage.

The four families

  • Business — Starter, Business, Enterprise. The full company workspace: accounting, invoicing, CRM, projects, inbox, AI Studio, shop.
  • Private — Basic, Plus, Premium. A personal area for your own paperwork. Basic is free and has no time limit.
  • Tax advisor — Solo, Team, Agency. Everything in the business workspace plus the Taxes module for managing tax clients.
  • Trustee — Essential, Professional, Institutional. Everything in the business workspace plus the Trust module for managing mandates.

Changing plan

  1. Compare the plans on the pricing page for your family.
  2. Choose the plan you want. Moving up takes effect straight away — the higher limits and any extra modules become available immediately.
  3. Moving down takes effect at the end of the period you have already paid for, so nothing is cut off mid-month.
  4. Check Central → Team afterwards if you moved down: a smaller plan includes fewer employees.
Prices are on the pricing pagesThis help centre never repeats a price, because a price in a help article is wrong the day it changes. Follow the pricing link for your family.
