Key takeaways
- Use one group per client relationship for requests and quick questions.
- Keep internal review discussions in staff-only groups.
- Send documents up to 25 MB; store final workpapers in your document system.
- Usernames and invitations mean staff do not share personal numbers with clients.
- Group records stay with the firm when staff leave during or after busy season.
Accounting firms spend a surprising share of their time chasing information: a missing bank statement, a receipt, a question about an unusual transaction. Clients prefer to answer by message, so staff often end up using personal WhatsApp, or long email chains that nobody can find a week later. During busy season that becomes a real risk, both for confidentiality and for missed deadlines.
Communication challenges in accounting firms
- Document chasing. Requests and reminders consume hours every week.
- Sensitive data. Tax IDs, payroll and bank details move through whatever channel is fastest.
- Seasonal staff. Temporary staff join for a few months and should not keep access afterwards.
- Review chains. Preparers, reviewers and partners discuss a file before anything goes to the client.
- Impersonation risk. Clients can be targeted by messages pretending to be the firm.
How accounting firms teams use C Chat
- Client group. One group per client with the assigned accountant, a manager and the client contact as a guest.
- Pinned request list. At the start of an engagement, pin the list of documents needed and update it as items arrive.
- Uploads with context. The client sends files up to 25 MB with a line saying what each one is. See exchanging documents securely in chat.
- Internal review happens in a staff-only group for that client or team, never in the client group.
- Status updates. Short messages when the return is filed or the monthly close is done, following client communication in a dedicated group.
Read receipts show whether the client has seen a reminder, which saves a follow-up call.
Recommended group structure
| Group | Members | Purpose |
|---|---|---|
| Client – [name] | Accountant, manager, client contact (guest) | Requests, questions, status |
| Team – [service line] – Internal | Preparers, reviewers, partner | Review notes, workload |
| Firm – Announcements | All staff | Deadlines, policy changes |
| Seasonal – [year] | Temporary staff and their leads | Onboarding and coordination |
The free plan supports up to 30 groups per team. Firms with many clients often create groups for active engagements and use direct messages for occasional clients, or split service lines into separate teams.
Guests: clients, contractors and vendors
Clients are the main guests, but the same model works for the client’s bookkeeper, a payroll provider or another adviser, each invited to the specific client group. Professional firms often share clients: law firms on estate and corporate matters, real estate teams on property transactions, and specialists such as private investigators on forensic work.
Many small business clients run service companies themselves. If you advise home service businesses, cleaning companies or security firms, you may notice they use the same group model with their own customers, for example cleaning crews and client sites, technician job photos and security client updates.
Security, privacy and audit
C Chat encrypts messages and files in transit with TLS and at rest with AES-256, with a key dedicated to your firm. Owners and admins can audit and export group conversations, which is helpful when a client disputes what was requested or when a staff member leaves. Direct messages between people stay private. The platform accesses content only for moderation of reported messages or legal requirements, and that access is logged.
If you currently use WhatsApp Business to talk to clients, C Chat vs WhatsApp Business compares the two fairly: WhatsApp Business is strong for reaching customers from a business number, while C Chat focuses on team-owned groups with audit and export. C Chat does not claim specific certifications; confirm your data protection obligations with your counsel.
Getting started
Start with five active clients and your internal team. Create a team at getcchat.com/c, pin a document request template, and invite clients by link or email with a short note explaining this is the firm’s official chat channel.
Frequently asked questions
How can accountants share documents securely with clients?
Use a channel the firm controls, encrypted in transit and at rest, and limit who can see each client's files. In C Chat, a client group with only the assigned accountant, a manager and the client contact keeps documents in one place. For large or highly sensitive files, your client portal may still be the better option.
Is it okay to request tax documents by chat?
Requesting documents by chat is common and convenient. Agree with the client on what they will send this way, keep the request list pinned in their group and move final versions into your document management system. Check your professional and data protection obligations with your counsel.
How do we avoid phishing through chat?
Tell clients which channel and which people will contact them, never ask for passwords or full card numbers by chat, and confirm unusual payment instructions by phone. Members can also block and report suspicious accounts.
Can C Chat replace our client portal?
No. C Chat is for conversation and quick file exchange. Signature workflows, organizers and long-term document storage belong in your portal and practice management tools.
