Gripp runs the business side of your agency: quotes, projects, hours, tasks and invoices. FlowMattic posts the moments that matter to Slack: an offer accepted or rejected, an invoice sent, a payment received, a task done. Account managers, project leads and finance follow the work without everyone needing to log into Gripp.

Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made templateAn accepted offer is new work. Posting it to the team channel lets the studio celebrate and lets project planning start booking people for the job.
Offer AcceptedSend Channel Message

Payment Created posts each received payment to a private finance channel, so the team knows which invoices are settled without running a report.
Payment CreatedNumber FormatterSend Private Channel Message
When an invoice is sent, Slack sets a reminder for the payment term, so someone checks whether it was paid and calls the client before it is weeks overdue.

A Router uses the project name on each finished task to post it in that project's channel, so the client lead sees progress without asking the team.
Task CompletedRouterSend Channel Message
Assignment Created makes a Slack channel named after the client and job, with the brief in its topic, so the team working on it has one place to talk.

A Filter passes purchase orders above your limit to a private channel, so the director sees big spending on freelancers or media before it is committed.

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Gripp and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Accepted and rejected offers show up in Slack, so the studio celebrates new work and account managers follow up on lost quotes.
Sent invoices, payments and purchase orders reach finance and directors without waiting for the monthly figures.
FlowMattic runs on your own WordPress site with unlimited runs, so adding more clients and projects adds no automation cost.
Add a Slack connection in FlowMattic, start a workflow with a Gripp trigger such as Offer Accepted or Invoice Sent, and add Send Channel Message. Map the client and amounts, test with a real event and switch it on.
Yes. Use Send Private Channel Message in the workflows that start from Invoice Sent and Payment Created, so only finance and directors see amounts.
Yes. Start from Assignment Created and use Create Channel. Later workflows, such as Task Completed, can use a Router on the project name to post into the right channel.
Yes. Company Created and Contact Person Created are separate triggers. Post them to a sales channel so the team knows a new client or contact was added.
