Approvals with buttons
Purchase requests, discounts, time off and change orders arrive with Approve and Decline buttons, and the decision is saved in the system of record.
Slack integration consulting
Connect Slack to the rest of your business.
Slack is where many teams already talk through the day's work. We build custom Slack apps that bring the right alerts, approvals and requests from your other systems into it, so people act without switching tools.
Keep it, then extend it
What Slack does well, and where teams outgrow it.
Where Slack shines
- Where conversations already happenChannels by team, client or project keep decisions in one place, and people check Slack all day.
- Workflows anyone can buildOn paid plans, Workflow Builder lets people set up simple flows from a form, a schedule or a message, without writing code.
- Shared channels with other companiesSlack Connect lets you work in a channel with clients, vendors or partners, each from their own Slack.
Where teams hit the limits
- The real work lives elsewhereThe order, ticket or invoice being discussed sits in another system, and someone copies details back and forth.
- Alerts become noiseGeneric notifications pour into channels with no owner and no next step, so important ones get missed.
- Decisions don't reach the recordAn approval given in a thread never makes it back to the ERP, CRM or project system without someone updating it by hand.
What we build around it
Connecting Slack to the rest of your work.
Alerts with an owner and a next step
A late shipment, a large deal or a failed payment goes to the right person with the details and a clear action.
Requests that become tickets
A short form in Slack creates the ticket, order or task in the right system and posts updates back to the thread.
An assistant that knows your data
Ask questions about orders, customers or policies in Slack and get answers drawn from your own systems, with sources.
Client and vendor channels kept in step
Updates from your systems post to shared channels so outside partners see status without another email.
Daily and weekly digests
A short morning summary of what changed, what's late and what needs a decision, posted where each team works.
Before we start
How access works.
We build a custom Slack app for your organization only, created under your workspace and installed by a Workspace Owner or app manager. If your workspace requires app approval, the owner reviews exactly which permissions the app asks for before it is installed (see Slack's app approval guide). On Enterprise organizations, an Org Owner or Admin can make the app available across workspaces. Because the app is built for your own organization rather than sold to others, the tighter limits Slack placed in 2025 on reading message history for apps distributed outside its Marketplace don't apply to it. We still design around Slack's request limits and ask only for the permissions each feature needs.

Common places to start.
Approvals stuck in email
The request went out on Monday. By Friday, nobody knows who has it. The person who needs to approve it never saw it, or forgot.

A good inquiry lands at 4:40 on a Friday. It sits in a shared inbox until Monday. By then the buyer has talked to two competitors, and one of them called back first.

Monday morning, four hundred new tickets. Someone reads each one to decide what it is and who should take it. The urgent outage report is ticket number 312.

FAQ
Common questions.
Isn't there already a Slack app for our CRM or ERP?
Often there is, and you should use it if it fits. Custom work makes sense when an alert or approval needs data from more than one system, or when a decision in Slack has to update your system of record.
Can people outside our company use it?
Yes, within limits. Workflows and updates can reach Slack Connect channels shared with clients or vendors, and we agree with your admin what outside people should see.
Can the assistant read every channel?
No. It only sees the channels and systems you approve, and answers respect the same permissions your team already has.
We use Microsoft Teams too. Can you do the same there?
Yes. See our Microsoft 365 page. Many organizations run both, and the same approvals and alerts can reach each team in the tool it uses.
Are you a certified Slack partner?
No. We're an independent integration consultant and development team. We build with Slack's official developer tools and approved access, using the access your team grants, and we work alongside your Slack admin or implementation partner rather than replacing them.
