Key takeaways

Small firms need quick set-up and simple pricing more than enterprise features.
Avoid per-user pricing that penalises adding a part-time helper.
Automated client reminders give sole practitioners the biggest time back.

What matters most for a small firm

Sole practitioners and small teams have little time for implementation. The right tool is one you can set up in days, with templates for common services and deadlines imported automatically.

Pricing should grow with clients, not staff, so bringing in a junior or a virtual assistant doesn't increase costs.

Features that save the most time

For small firms, the biggest wins are usually:

Companies House deadline import
Automated client record requests
Proposal and engagement letter templates
A client portal instead of email attachments

How we assessed these tools

We compared tools against what UK accountancy firms need day to day: CRM and lead pipeline, Companies House and HMRC deadline tracking, proposals and engagement letters, client portal, workflow, AML records, UK support, pricing model and free trial.

Remindoo is our own product, so treat our view of it accordingly. Competitor details change often — check each vendor's current public pricing and features before you decide. Where we could not confirm a detail, we have not stated it.

Is pricing per user or per client — and what happens as the team grows?
Is there UK-based support and help with migration?
How long is the free trial and what does it include?

Frequently asked questions

Is Remindoo suitable for sole-practitioner accountants?

Yes. Pricing is per active client with unlimited users, and a single client is the minimum, so it works for sole practitioners and grows with the firm.

Why recording every task matters in an accountancy practice

Accounting firms run on deadlines: VAT returns, payroll, confirmation statements, accounts and Self Assessment. Recording every job as a task, with an owner and a date, is the simplest way to make sure nothing is missed.

Avoid penalties

HMRC and Companies House charge penalties for late filing. A task for every deadline, with an internal date before it, gives the team a buffer.

Nothing depends on memory

Recorded tasks mean work continues when someone is off sick, on leave or has left the firm.

Consistent quality

Subtask checklists make every job follow the same steps and reviews, whoever does the work.

Visibility for managers

Filters by owner, status and deadline show at a glance what is late, what is due and who needs help.

Practical tips from UK practice

Set an internal deadline two to four weeks before every statutory deadline.
Use recurring tasks for repeat work such as VAT, payroll and bookkeeping.
Break larger jobs into subtasks, including a review step.
Comment on the task instead of by email, so the history stays with the work.
