The January panic. Every year.
Clients forget. Deadlines approach. You chase paperwork instead of doing billable work.
Documents arrive late
40% of clients submit documents after you've requested them. Self Assessment crunch time becomes unbearable.
Hours lost chasing
Phone calls, emails, follow-ups. Non-billable time that could be spent on actual accounting work.
HMRC penalties
Late Self Assessment filing costs clients at least £100. Late VAT returns mean surcharges. They blame you.
The UK tax calendar is relentless
Automated reminders that actually get read
SMS open rates exceed 98%. Set up reminder sequences once. Documents arrive on time. Every time.
One system for every deadline
Hi Sarah, your Self Assessment deadline is 31 Jan.
Please send by 15 Jan:
- P60 from employer
- Bank interest certificates
- Dividend vouchers
- Property income/expenses

What Remindlo users say
“Easy to install and setup new campaigns for small and medium businesses. Free up to 10 SMS per month so you can try without worrying about the bill.”
“I run a small biz and that plugin saves me a ton of time. Works in the background, since I also enabled the auto-sync option. No extra work for me, events with phone numbers are picked up automatically for the reminders; I'm already busy with other stuff so that's good. Using two out of three default workflows - per-visit reminders and post-visit thank you notes to collect reviews.”
