Slash commands and shortcuts
Commands and message shortcuts that open the right form or fetch a record without leaving Slack.
The Problem
Your Team Runs on Slack, but the Work Still Lives Somewhere Else
It shows up as threads nobody closes, alerts nobody owns, and the same status question asked three times a day in different channels.
01 · Lost approvals
Requests sit in threads until someone remembers to reply.
Approve and reject buttons record each decision inside the message.
02 · Noisy alerts
Raw alerts scroll past and nobody takes ownership.
Alerts arrive with acknowledge and assign buttons, so one person owns each.
03 · App hopping
People open three tools just to check a status.
A Home tab shows open requests and their status inside Slack.
04 · Customer installs
Customers want your app, but unlisted apps face tight limits.
We build to Slack Marketplace rules, so customer installs aren't throttled.
Someone posts a purchase request in a channel, and it sits there until the right manager scrolls past it. Your monitoring tool drops raw alerts into another channel, and three people look while nobody takes it. A customer asks your sales team for a Slack integration, and the honest answer is a webhook URL. Each answer means opening another app, finding the record, and coming back to reply. By Friday nobody can say which requests were approved.
We start with the requests and alerts your team already handles in Slack, then build Slack app flows that turn each one into a message with buttons. Approvals record who decided and when, alerts get an owner, and a Home tab shows what is still open. Decisions happen in the message, not in a thread that scrolls away.
Buttons instead of thread replies
Approve, assign, or reject from the message itself, with the decision saved.
Scopes your security team approves
We list every OAuth scope and why it's needed before anything is installed.
Built for Slack's API rules
Rate limits, the 3-second reply rule, and Marketplace terms planned in from the start.
Our Slack App Development Services Process
From Request Map to Rolled-Out Slack App in Five Clear Steps
You approve every message, button, and OAuth scope before code starts, and one team pilots the app in a real channel before everyone gets it.
We map the requests, approvals, and alerts your team handles in Slack today, and the systems behind them. You get a list of commands, buttons, and messages with a fixed quote. If Workflow Builder already covers it, we'll tell you before we quote.
What's Included
What You Get With Slack Bot Development Services
Commands, approvals, alerts, a Home tab, and the connections to your systems, built on Bolt and hosted where your security team can see it.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built websites, apps, and integrations for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Operations and SaaS Teams Trust Us With Their Slack App
A Slack app talks to your whole company several times a day. These habits keep it useful, quiet when it should be, and safe to approve.
Fewest scopes possible
We ask for the OAuth scopes each feature needs and nothing extra. Security reviews go faster, and the app can see less if a token leaks.
Messages people can scan
Each message leads with the decision needed and the one number that matters. People act on short messages and ignore long ones.
Pilot with one team first
One team uses the app for a week before everyone else gets it. Their complaints fix the wording before the company sees it.
Rate limits planned in
We queue and retry calls so busy hours don't hit Slack's limits. Your alerts keep arriving on the day you need them most.
One price per flow
Each command, approval, and alert is priced in the proposal before we start. Extra requests get a quote first, so the agreed total holds.
Your app, your workspace
The app config, code, and hosting sit in your accounts. Your team can change commands or scopes later without us.

Good fit
Operations teams buried in requests
Your team handles purchase, access, or refund requests in Slack threads, and approvals get lost when someone forgets to reply.
Engineering teams with noisy alerts
Your monitoring tools post raw alerts into a channel, and nobody can acknowledge or assign them without opening other apps.
SaaS companies adding Slack
Your customers want your product's updates in Slack, and you need an app they can install from the Slack Marketplace.
Companies on Slack Enterprise
Your company runs an Enterprise org with many workspaces, and the app must install once for everyone and pass your security review.
Agencies with Slack-first clients
Your agency's clients run on Slack and ask for custom bots, and you need a Slack bot developer who can build and host them.
Not a fit
Simple forms or reminders
You need a simple form, reminder, or welcome message. Slack's own Workflow Builder handles that on paid plans without custom code.
Community on Discord
Your members gather in a Discord server, not a Slack workspace. Our Discord Bot Development Services page covers bots for community servers.
Sync with no Slack step
You only need records copied between two tools, with nobody acting in Slack. Our Workflow Automation Services page covers that kind of work.
Training AI on Slack data
You want to collect Slack messages to train an AI model. Slack's rules for apps don't allow that, so we turn the work down.

Send a message or book a call with the team.
Slack app development with us starts at $750 for an internal bot with up to 3 commands and alerts from one system. Workflow apps with approvals, modals, and a Home tab are $2,100, and Marketplace-ready apps start at $4,900. You get a fixed quote after a free request review.
An internal bot usually takes 2 to 3 weeks, and approval apps with modals and a Home tab take 4 to 8 weeks. Marketplace apps then wait for Slack's review. Slack's guide allows up to 10 business days for the first check and up to 10 weeks of functional review for a new app.
A Slack bot is an app that talks with people in Slack through messages, commands, and buttons, using its own bot token. It isn't the same as Slackbot, which is Slack's built-in assistant. A custom bot stays installed when the person who added it leaves, because the token belongs to the app.
You create a Slack app from a manifest, either in the app settings or with the Slack CLI. The manifest lists the app's name, scopes, commands, and event subscriptions. Installing it to your workspace then gives the app a bot token for Slack's Web API.
Give the app the chat:write scope, then post from your system with Slack's chat.postMessage method. Slack allows about one message per second per channel, so busy systems need batching. We add buttons to each alert, so someone can acknowledge or assign it without leaving the message.
Register the command in the app's settings, then have your server acknowledge each request within 3 seconds, which Slack requires. Longer work finishes in the background and posts the result back to the channel. Bolt handles that acknowledgment for you, which is one reason we build on it.
You make it with Block Kit, Slack's layout framework for messages, modals, and the Home tab. A message holds up to 50 blocks and a modal up to 100. When someone clicks a button, Slack sends your app an interaction, and the app updates the message to show the decision.
Build a Slack bot as a distributed app with an OAuth install flow, then list it in the Slack Marketplace. Slack's 2025 terms make the Marketplace the channel for commercial distribution, and unlisted commercial apps get far lower limits on reading message history. Submission needs 10 or more active workspaces.
Yes, a Slack app can run an AI agent in Slack's agent messaging experience, which new apps use since June 2026. The app needs the assistant:write scope and can stream replies as they're written. Slack's MCP server and Real-time Search API are limited to Marketplace and internal apps, so we settle the app type first.
You do. The app is created in your Slack account, the code lives in your Git repository, and hosting runs in your cloud account. Every plan includes 30 to 90 days of support. We also hand over the app manifest, so your team can change scopes or commands later.
