Who are we?
Operating across Europe and Asia, WeMaintain specialises in the maintenance and modernisation of lifts, escalators, automatic doors and fire safety systems, combining hands-on technical expertise with technology and data.
Our approach is built on a simple belief: maintenance can be more reliable, transparent and effective when teams have the right tools, the autonomy to make decisions and a clear understanding of what’s happening across the equipment they look after.
Since 2026, Otis has been our majority shareholder. WeMaintain continues to operate independently, retaining its own organisation and culture while benefiting from additional resources to support our growth.
Three core values guide the way we work every day: Care (looking after others): treating colleagues and customers with respect, consideration and a genuine sense of responsibility. Grit (determination): seeing things through with high standards, commitment and perseverance. Uniqueness (being different): embracing different perspectives, fresh ideas and new ways of doing things.
Our ambition is to raise the standards of maintenance, alongside the people who make it happen every day.

We’re looking for a Finance Assistant to join our Finance team as maternity leave cover. You’ll support day-to-day finance operations, with a particular focus on customer billing, payment allocation, credit control, account reconciliation, query resolution and month-end activities.
Accurate billing and clean customer accounts matter to our customers and to the teams who look after their equipment. You’ll work closely with Operations and other internal teams to keep billing and account information right, and with the wider Finance team on month-end and audit.
What you’ll do
- Generate accurate customer invoices and credits in NetSuite, matching POs in line with billing schedules.
- Manage customer billing portals and handle customer queries by email and phone.
- Manage credit control, follow up on overdue debt and escalate issues where needed.
- Allocate customer payments, reconcile customer accounts and produce clear statements.
- Support month-end, including revenue recognition, checking contract information in Salesforce and NetSuite, and helping with closing and audit.
- Resolve billing and account queries, making adjustments and credits where required.
- Work with internal teams to keep billing and customer account information accurate and up to date.
- Help with ad hoc finance tasks and support the wider Finance team.
Who we’re looking for
Someone with a finance background who is comfortable with high volumes, precise in their work and clear in how they communicate with customers and colleagues.
What you’ll need
- A finance background
- Some experience with accounting software
- Good knowledge of Excel and Google Sheets
- The ability to handle large volumes of billing and query resolution
- Effective verbal and written communication
- Familiarity with business principles and practices
- A hands-on approach, good interpersonal skills and a can-do attitude
What would make you stand out
- Experience with NetSuite
What you should know before joining us
A fixed-term role: this is maternity cover, running from November 2026 to January 2028.
High volumes: you’ll handle a large flow of invoices, payments and customer queries.
Month-end deadlines: closing, revenue recognition and audit support come with fixed timelines.
This role will particularly suit someone who enjoys accuracy, routine and resolving queries end to end. It may be less suited to someone looking for a permanent position.
What we offer
A hands-on finance role at the heart of our billing and customer account processes.
Experience with NetSuite and Salesforce in a growing international business.
An international environment with colleagues across Europe and Asia.

Welcome to WeMaintain!
We carefully review every application. We’re not necessarily looking for someone who ticks every single box on a job description, and we know that the strongest career paths aren’t always the most conventional.
We also recognise that women, in particular, can be less likely to apply for a position unless they meet every listed requirement. So, if you’re reading this and thinking, “This role sounds like a great fit, but I don’t quite tick every box”, we’d genuinely encourage you to apply anyway. What matters most to us is what you can bring to the role, how you think, how you collaborate with others and the impact you could have at WeMaintain.
We value diversity in backgrounds, experiences and perspectives, and we’re committed to creating an inclusive working environment. Every application is considered fairly, regardless of background, gender, age, disability, sexual orientation, beliefs or personal circumstances.
