Client Onboarding Software for Accounting Firms
Onboard new accounting clients on a repeatable track: engagement letter, e-signature, document requests, portal access and first engagement set up.
Client onboarding software gives an accounting firm one repeatable track from signed proposal to first delivered engagement: engagement letter, e-signature, information and document requests, portal access, client record setup and the first recurring work created. Remindoo runs onboarding as a workflow against the client record.

Key facts
- Onboarding starts from the signed proposal, so scope and services carry over without re-keying.
- Engagement letters sent and signed electronically, stored on the client record.
- Document and information requests tracked with automated reminders while they are outstanding.
- Portal access issued as part of the track, not as a separate afterthought.
- Services set up on the record generate the client's recurring work and due dates.
- 60-day free trial of the full platform; a card is required to start it.
Onboarding is where firms lose the most goodwill
The gap between a client saying yes and a firm doing useful work is the part of the relationship clients remember. It is also, in most firms, the least standardized process they run. The engagement letter goes out when a partner gets to it. The document request is a long email written from scratch. Portal access is set up when someone notices it has not been. Three weeks pass, and the client's first experience of the firm is waiting.
None of that is a motivation problem. It is a process problem: onboarding involves six or seven steps, several of which depend on the client, and nobody owns the whole sequence. The moment it becomes a tracked workflow with owners and dates, the elapsed time falls without anyone working harder.
A repeatable onboarding track
The sequence below is what most US firms need, in order.
- Convert the signed proposal to a client record with the agreed services
- Issue the engagement letter for electronic signature
- Send the information and document request the client needs to respond to
- Chase outstanding items automatically rather than manually
- Give the client portal access and show them where to upload
- Collect prior-year records, entity details and access to ledgers
- Set up the recurring engagements and due dates for the services purchased
- Introduce the client to their named point of contact and hand over internally
Why automated chasing changes the math
The single biggest cost in onboarding is not firm effort — it is client latency. Requests sit because the client is busy, and staff either chase manually, which is expensive and inconsistent, or do not chase, which is worse. Automated reminders on open requests remove that decision: the client hears from the system on a schedule, and staff only get involved when the reminder has not worked.
The secondary benefit is a clean record of what was requested and when. When a client says they sent something, the request history answers the question in seconds rather than through a search of three inboxes.
Frequently asked questions
How long should onboarding an accounting client take?
Most firms can move from signed engagement letter to first productive work within one to two weeks when the track is standardized and chasing is automated. The variable is almost always how quickly the client returns documents and access, which is why automated reminders have more effect than internal process changes.
What should an accounting client onboarding checklist include?
At minimum: signed engagement letter, client and entity details, contacts and authorized signers, prior-year records, access to the ledger and any payroll or sales tax systems, agreed scope and fees, portal access, a named point of contact, and the recurring work set up for each service purchased.
Does Remindoo handle engagement letters and e-signatures?
Yes. Engagement letters can be sent for electronic signature from the client or prospect record, and the signed document stays attached to that record. That means it is available during onboarding, throughout the engagement and at renewal without searching through email threads.
Can onboarding differ by service line?
Yes, and it usually should. A monthly bookkeeping client and a once-a-year individual tax client need different requests, different access and different setup. Running onboarding as a workflow lets you keep one track per service rather than one generic track that fits neither well.
How do we stop chasing clients manually?
Move requests out of email and into tracked items the system can remind against. Outstanding requests then generate their own reminders on a schedule, and staff intervene only when automated chasing has not produced a response, which is a much smaller share of cases than most firms expect.
Does Remindoo run identity or risk checks on new clients?
Remindoo includes AML risk assessment and client due-diligence workflow. How US firms use it depends on their own obligations and professional standards; the software records and tracks the checks your firm decides to perform. It does not determine what your firm is required to do.
