Written support
BILLY doesn't have a phone number. Support is handled in writing: via your accountant's email address or the live chat in the app.
Why in writing?
By receiving your questions in writing only, nothing gets lost. Everything is tracked and we have a complete history.
It also means more accurate handling — we take the time to analyse your question by looking at the full context of your situation.
And finally, we're able to point you in the right direction: your request is handled either by the customer service team or by your dedicated accountant.
The cherry on top: we often manage to reply within minutes via live chat.
Hours and response times
Our team is available:
Monday to Thursday: 9am to 12:30pm and 1:30pm to 5pm
Friday: 9am to 12:30pm and 1:30pm to 4pm
Maximum response times vary depending on the channel used:
Via live chat (Customer Service team): 2 hours (during business hours)
Via email (directly to your accountant): 2 business days
Would you like to schedule a meeting?
Your dedicated accountant organises remote check-in and advisory meetings. They'll suggest times by sending you a booking link directly from their calendar. These meetings take place by phone or video call.
On your end, if you need a meeting, simply request one via live chat or email, explaining the topic you'd like to discuss. Your accountant can then set aside the right amount of time and prepare the necessary information.
Where to find the live chat?
To contact our customer service team, simply send a written message via live chat or email your accountant.
You can access the live chat via the small bubble at the bottom right of your screen:

See you soon on BILLY
