Client communication tools for agencies in 2026: 7 tools compared
Written by Bilal Azhar, Co-Founder & CEO, AgencyPro | October 13, 2026
The right client communication tool for an agency depends on where your clients already talk. Clients who live in Slack answer fastest in Slack Connect. Clients who email need a shared inbox such as Front or Help Scout. Project decisions, files, approvals and invoices are easier to track in a client portal. This guide compares seven client communication tools across those four types, with pricing for a 5- and 10-person team.
AgencyPro is our product. The list is grouped by type of tool, not ranked, and each entry says when to pick something else. Facts and prices come from each vendor's own site, checked October 13, 2026.
How we compared these tools
This is a criteria-based comparison based on each vendor's published features and pricing, checked October 2026. It is not a hands-on test or a scored ranking. We recorded the same facts for every tool so you can repeat the check:
- Channel type: shared chat, shared inbox or help desk, client portal, or async video.
- What the client must do: use a paid plan, create a login, or keep using email.
- History: whether conversations stay searchable and whether any plan limits history.
- Structure: assignment, tickets or requests, SLAs, and approvals tied to the conversation.
- Cost at 5 and 10 seats: the published per-seat or tier price for a team of that size.
- Connections: Slack, email-to-ticket and live chat options that let tools work together.
Prices change. Confirm them on each vendor's pricing page before you buy.
The four types of client communication tool
Most lists mix customer-support software with team chat. For an agency, it helps to separate tools by the job they do.
Fastest replies. Weakest record of decisions. Works only if the client is on Slack.
Clients keep emailing. Your team assigns and tracks replies.
Messages sit next to requests, files, approvals and invoices. Clients need a login.
Recorded walkthroughs that replace short calls. Sent through one of the channels above.

What a 5- and 10-person agency pays per month
Starting prices hide the real cost, and most agencies pay for two of these tools at once. This table applies each vendor's published seat or tier rules to a team of 5 and 10.
| Plan | 5 people | 10 people | How it is calculated |
|---|---|---|---|
| Slack Pro | $43.75 | $87.50 | $8.75 x users. Your client also needs a paid Slack plan to join a shared channel. |
| AgencyPro Basic | $99 | $174 | $39 + $15 per extra seat. Messaging, portal, files and invoicing. Clients free. |
| AgencyPro Pro | $159 | $259 | $79 + $20 per extra seat. Adds tickets, email piping and SLA tracking. |
| Front Starter | $125 | $250 | $25 x seats, billed annually. Starter tops out at 10 seats. |
| Help Scout | $0 | $250 | Free plan covers 5 users and 1 inbox. Standard is $25 x users, billed annually. |
| Assembly | $249 | Not published | Advanced includes 5 internal users. Professional ($99) covers 3. Extra-user price not listed. |
| ManyRequests Core | $139 | $239 | $59 + $20 per extra seat. Slack integration needs Pro ($99 + $30 per seat). |
| Loom Business | $90 | $180 | $18 x users, assuming everyone records. The free Starter plan may cover light use. |
Front and Help Scout show annual-billing prices by default; monthly billing costs more. Example stack: a 10-person agency using Slack Pro internally and with a few clients, plus AgencyPro Pro for everyone else, pays $87.50 + $259 = $346.50/mo.
The 7 tools in detail
Best for: Real-time conversation with clients who already use a paid Slack plan
Pricing: Free plan allows 1:1 external DMs only. Pro $8.75/user/mo ($7.25 annual), Business+ $18/user/mo ($15 annual).
Slack Connect lets you share a channel or DM with people at another company. The client sees the channel inside their own Slack, and you see it next to your internal channels. For clients who already work in Slack, it is the fastest way to get an answer.
Two plan rules matter. Slack says that to work in channels together, each organization must be on a paid plan; on any plan you can only DM. And the Free plan keeps 90 days of message history, so decisions older than that disappear from search unless you pay. Paid plans keep full history.
Pros
- - No new login for clients who already use Slack
- - Fast replies and easy file sharing
- - Shared channels can include up to 250 organizations on paid plans
Cons
- - Shared channels require a paid plan on both sides
- - Each client channel adds notifications for your team
- - No approvals, invoices or request tracking; decisions get buried in chat
Verdict: Use it for a short list of high-touch clients who live in Slack. Put files, approvals and billing somewhere with structure. How AgencyPro sends notifications to Slack.
AgencyPro
Best for: Agencies that want client messages stored next to requests, files, approvals and invoices
Pricing: Basic $39/mo, Pro $79/mo, Plus $149/mo. Each plan includes 1 seat; extra seats are $15, $20 or $30/mo.
AgencyPro is a client portal with messaging on every plan. Clients log in to message your team, attach files, follow requests, approve work and pay invoices. Messages support group conversations, file attachments, read receipts and search, so you can find what a client agreed to without digging through email.
On the Pro plan, support tickets with priorities and reply templates, email piping (client emails become requests or tickets) and SLA tracking for response and resolution times are added. The Slack integration posts events such as new requests, new tickets and paid invoices to a Slack channel for your team, and you can embed a live chat widget from providers such as Intercom, Crisp or Tawk.to in the portal.
One customer review on Trustpilot, from Mrake Angelo Miguel, says AgencyPro "replaces the patchwork of tools we used to rely on with one cohesive system, so our team and our clients aren't constantly context-switching." That is one customer's experience, not a test result.
Pros
- - Messaging, files, requests and invoices in one client-facing place
- - Client logins are free and clients are unlimited on every plan
- - Email piping lets clients keep emailing while work is tracked (Pro)
- - Slack notifications and live chat embeds for teams that use them
Cons
- - Seats cost extra: 10 people on Pro is $259/mo
- - Tickets, email piping and SLA tracking need Pro, not Basic
- - Clients have to adopt a portal; the Slack integration notifies your team rather than creating a shared client channel
- - Not a shared email inbox with SMS or WhatsApp channels
Verdict: A good fit if you want one record of client conversations tied to the work and the billing. If your clients refuse to leave Slack or email, start with Slack Connect or a shared inbox instead. See the AgencyPro client portal.
Best for: Agencies whose clients email, and where several people answer
Pricing: Starter $25/seat/mo (up to 10 seats), Professional $65/seat/mo (up to 50 seats), Enterprise $105/seat/mo. All billed annually.
Front turns email into a shared team inbox. Your team can assign client emails, comment internally without forwarding, and use rules to route messages. Its pricing page lists shared inboxes and ticketing on every plan, and a customer portal with ticket forms.
Starter supports a single channel type with up to 10 automation rules and basic analytics. Professional adds omnichannel (email, SMS, social and WhatsApp), more rules and advanced analytics. Clients do not need to learn anything new because they keep using email.
Pros
- - Clients keep using email; nothing for them to adopt
- - Assignment and internal comments stop the forward-and-cc chain
- - 14-day free trial without a credit card
Cons
- - Per-seat pricing; omnichannel starts at $65/seat on Professional
- - Starter allows only 10 seats and one channel type
- - Project files, approvals and invoices still live in other tools
Verdict: Pick Front if email is your main client channel and you have several people replying. Pair it with a project or portal tool for deliverables. Compare with AgencyPro email piping.
Best for: Agencies whose client communication looks like support requests (hosting, maintenance, IT, ad operations)
Pricing: Free (up to 5 users, 1 inbox). Standard $25/user/mo, Plus $45/user/mo, Pro $75/user/mo. Prices shown billed annually.
Help Scout is a help desk built around a shared inbox, a knowledge base (Docs) and a live chat widget (Beacon). Its Free plan covers up to 5 users with 1 inbox and 1 Docs site, which is enough for a small agency handling maintenance requests.
Paid plans add inboxes, Docs sites and SLAs: Standard includes 1 basic SLA, Plus includes 2 advanced SLAs and 5 inboxes. The model fits agencies that answer recurring questions; it fits less well when communication is mostly strategic discussion on a project.
Pros
- - Free plan for up to 5 users
- - Knowledge base and live chat in the same product
- - 15-day trial of Standard or Plus without a card
Cons
- - Support-ticket framing does not suit project discussion
- - SLAs are limited on Standard and absent on Free
- - No project files, approvals or invoicing
Verdict: Choose Help Scout when clients send repeat support questions and you want a knowledge base to answer them. Keep project work elsewhere. Compare with AgencyPro tickets.
Best for: Service businesses that want a branded client portal with messaging and a team inbox
Pricing: Free (1 internal user, 5 contacts). Starter $49/mo ($29 annual). Professional $99/mo ($79 annual). Advanced $249/mo ($199 annual).
Assembly, which rebranded from Copilot in September 2025, lists messaging and a team inbox on every plan. Clients message your team, share files, sign contracts and pay from a branded portal, and Assembly says it is SOC 2 Type II certified.
Pricing is set by internal users and active client contacts: Starter covers 1 internal user and 50 contacts, Professional 3 users and 500 contacts, Advanced 5 users and unlimited contacts. Custom domain and branding removal start on Professional.
Pros
- - Messaging and team inbox on every plan, including Free
- - Published SOC 2 Type II claim
- - Free plan to try the client experience
Cons
- - Contact limits (5, 50, 500) can force an upgrade as client count grows
- - Custom domain not on Free or Starter
- - Extra internal-user pricing not published
Verdict: A reasonable choice for a small service team that wants a polished portal and a predictable number of client contacts. AgencyPro vs Assembly.
Best for: Productized and subscription agencies where conversation happens on each request
Pricing: Core $59/mo ($39 annual), Pro $99/mo ($79 annual), 1 seat included. Extra seats $20 or $30/mo.
ManyRequests organizes client communication around requests. Its pricing page lists messaging in the client portal, internal comments, @mentions and reply via email on every plan, so clients can answer a notification without logging in.
Customizable email notifications and the Slack integration (a custom Slack app with notifications for your team and clients) are Pro features. Invited clients do not count as seats.
Pros
- - Reply via email on every plan
- - Request-first threads keep conversation attached to the work
- - Clients do not count as seats
Cons
- - Slack integration and custom notifications need Pro
- - Per-seat pricing grows with the team
- - Request-first model feels rigid for open-ended discovery work
Verdict: Shortlist it if you sell subscriptions or a service menu. It overlaps with AgencyPro, so trial both on your own request flow. AgencyPro vs ManyRequests.
Best for: Recorded walkthroughs and status updates that replace short calls
Pricing: Starter free (25 videos per person, 5-minute limit). Business $18/user/mo ($15 annual). Business + AI $24/user/mo ($20 annual).
Loom records your screen and camera and shares the video as a link. Viewers can react and leave comments on the video, and transcripts and captions are included. AI summaries, chapters and filler-word removal are on Business + AI and Enterprise only.
Loom is a layer on top of your main channel, not a replacement for it. Send the video through Slack, email or your portal, and keep the reply and any decision in that channel.
Pros
- - Replaces many short status calls
- - Free plan covers occasional use
- - Comments and reactions on the video itself
Cons
- - Mostly one-way; real back-and-forth happens elsewhere
- - Free plan caps videos at 5 minutes and 25 per person
- - AI features need the higher Business + AI plan
Verdict: Add it to whichever channel you choose. It is the cheapest way to make written updates clearer. Collaboration tools for agencies.
Common agency setups
Solo or 2-3 people with a handful of clients: Email plus Loom for updates is often enough. Add a portal when you start losing track of files and approvals.
5-20 people with retainer clients: A client portal (AgencyPro, Assembly or ManyRequests) as the record of decisions, Slack Connect for the few clients who insist on Slack, and Loom for weekly updates.
Email-led agency with several people replying: Front or Help Scout for the inbox. If you want those emails to become tracked work items instead, AgencyPro email piping (Pro) does that inside the portal.
Productized or subscription service: ManyRequests or AgencyPro, so every conversation is attached to a request.
Maintenance, hosting or IT support work: Help Scout for tickets, SLAs and a knowledge base. AgencyPro Pro also has tickets and SLA tracking if you want them next to billing.
Enterprise clients on Microsoft Teams: Ask early whether their IT allows external chat. If not, use email or a portal and keep calls on their platform.
What to test during a free trial
- - Send a message as the client. Use a personal email address and a phone. Count the steps from notification to reply.
- - Find a decision from last week. Search for a phrase the client used. If it takes more than a minute now, it will take longer in six months.
- - Hand a thread to a colleague. Assign it, add an internal note and check the client cannot see the note.
- - Reply from email. See whether a client email reply lands in the right thread or creates a duplicate.
- - Price your real team. Multiply the seat price by everyone who will reply to clients, not just the account managers.
When AgencyPro is not the right fit
- - Your clients will only use Slack. AgencyPro's Slack integration sends notifications to your team's channel. It does not create a shared channel with the client. Use Slack Connect.
- - You need an omnichannel inbox. If clients reach you by SMS, WhatsApp and social as well as email, Front Professional is built for that.
- - You only need a help desk on a tight budget. Help Scout's Free plan covers 5 users. AgencyPro tickets and SLA tracking need Pro, which is $159/mo for 5 people.
- - You want recorded video updates. AgencyPro's video annotation (Pro) is for reviewing deliverables, not recording walkthroughs. Use Loom and share the link in the portal.
- - Large team, chat only. At 20 people, AgencyPro Pro is $459/mo ($79 + 19 x $20). If you only need chat, Slack Pro costs $175/mo for 20 users.
How to choose: 5 questions
1. Where do your clients already talk?
Paid Slack: Slack Connect. Email: Front, Help Scout or email piping into a portal. Neither, or a mix: a client portal.
2. Do conversations end in approvals, files or invoices?
If yes, a portal keeps the decision next to the deliverable. Chat and inbox tools need a second system for that.
3. Do you need response-time targets?
Help Scout includes SLAs from Standard, AgencyPro on Pro. Slack Connect has no SLA tracking.
4. How many people reply to clients?
Every tool here charges per user or by tier. Run the 5- and 10-person math above for your headcount.
5. How far back will you need to look?
Slack Free keeps 90 days of history. Paid Slack, inbox tools and portals keep full history. Pick a tool where a scope decision from last year is still searchable.

Frequently asked questions
What are the best client communication tools for agencies?
It depends on how your clients like to talk. For real-time chat with clients already in Slack, use Slack Connect. For email-led work with several people replying, use a shared inbox like Front. For support-style requests, use a help desk like Help Scout. For project communication tied to files, approvals and invoices, use a client portal such as AgencyPro, Assembly or ManyRequests. Loom adds recorded updates on top of any of them. AgencyPro is our product.
What are examples of client communication tools?
There are four common types: shared chat (Slack Connect, Microsoft Teams), shared email inboxes and help desks (Front, Help Scout), client portals with messaging (AgencyPro, Assembly, ManyRequests) and async video (Loom). Most agencies use one primary channel plus one or two supporting tools.
Should I use email or a client portal for client communication?
Use both, with clear roles. Email works for quick notes and is the channel every client already has. A portal is better for anything you will need to find later: approvals, files, scope changes and invoices. Portals send email notifications that link back to the item, so clients do not have to remember to log in. In AgencyPro, email piping (Pro plan) turns client emails into requests or tickets, so clients can keep emailing while the work is tracked.
Is Slack Connect or a client portal better for clients?
They do different jobs. Slack Connect is better for fast back-and-forth with clients who already use a paid Slack plan, since shared channels require a paid plan on both sides. A portal is better for structured work: requests, files, approvals and invoices, with a history you can search later. Many agencies use Slack Connect for a few high-touch clients and a portal for everyone else.
How much do client communication tools cost for a 10-person agency?
As of October 2026: Slack Pro is $87.50/mo for 10 users. Front Starter and Help Scout Standard are each $250/mo billed annually. AgencyPro is $174/mo on Basic or $259/mo on Pro ($79 + 9 extra seats at $20). ManyRequests Core is $239/mo. Loom Business is $180/mo if all 10 people record. Most agencies combine two of these, so budget for the pair, not one tool.
What features should a client communication tool have?
Check five things: searchable history that does not expire, file attachments, email notifications that bring clients back to the right thread, a way to assign and track client requests, and permissions so each client sees only their own conversations. If clients approve work or pay invoices, it helps when those happen in the same place as the conversation.
How do I stop client conversations spreading across channels?
Agree the rules during onboarding: which channel is for project decisions, which is for urgent issues and where invoices go. Then route stray messages back. If a decision happens on a call or in a text, post a short summary in the agreed channel the same day so the rest of the team can see it.
Can I add live chat or Slack to a client portal?
In AgencyPro, yes. You can embed a live chat widget from providers such as Intercom, Crisp, Tawk.to, LiveChat or Zendesk in the client portal, and connect Slack so your team gets notified when requests are created or completed, tickets come in or invoices are paid. The Slack connection notifies your team; it does not create a shared Slack channel with the client.
Should internal team chat and client communication use the same tool?
Keep them separate where you can. If clients and staff share one workspace, it is easy to post an internal comment in a client-visible place. Use Slack or Teams internally, and give clients either a Slack Connect channel, a shared inbox or a portal where they only see their own conversations.
Keep client messages next to the work
AgencyPro puts messages, requests, files, approvals and invoices in one branded portal. The 14-day trial includes Pro features such as tickets, email piping and SLA tracking.
