Contractors draw in ArcSite on site and send the proposal from the truck. FlowMattic posts what happens next to Slack: the proposal went out, the customer approved it, the PDF came back signed, the drawing was revised. Sales, estimating and install crews follow each job from the channel without opening the ArcSite dashboard.

ArcSite and Slack workflows you can build
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 template
Ring the bell in sales when a proposal is approved
An approved proposal is a won job. Posting it to the sales channel lets the team see the win and lets the office start scheduling materials the same morning.
Open a job channel when a signed proposal comes back
The signed PDF is the start of the install. A new channel named after the customer gives the crew, the estimator and the office one place for questions about that job.
Proposal PDF Signed→Text Formatter→Create Channel→Set Channel Topic
Remind the rep to chase a proposal after three days
When a proposal is sent, Slack sets a reminder for the rep three days later. If the customer has not answered by then, the rep calls while the visit is still fresh.
Proposal Sent→Find User by Email→Add Reminder
Tell estimating when a drawing is revised
A changed drawing can change the price. The estimating channel hears which drawing was updated so the quote is checked before the customer signs the old numbers.
Drawing Updated→Send Channel Message
Post each new project to the office channel
Every new ArcSite project appears with the customer and address, so the office knows a site visit happened and can create the job in the accounting system.
Project Created→Send Channel Message
Send large approvals to the owner as a direct message
A Filter passes approvals above the amount you set. The owner gets a direct message for the big jobs, while the sales channel still hears about every approval.

Triggers and actions in this pair
A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Good to know
Slack channel names must be unique and lower case, with no spaces. Use Text Formatter to turn the customer name into a valid name and add the project number for repeat customers.
Drawing Updated fires on each save, and drawings are often saved many times on site. Send it to a quieter estimating channel, or add a Filter, so the main channel is not flooded.
The proposal fields in the mapping are typical examples. Check the captured test data to see which customer and price fields your ArcSite account sends.

Why run this pair with FlowMattic
ArcSite and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Field work reaches the office
Projects, drawings and proposals started on a tablet at the customer's site show up in Slack for the people who order, schedule and invoice.
Wins are seen by the whole team
Approvals and signatures post to the channel, so sales and install hear about a new job at the same time.
No charge per proposal
FlowMattic runs on your own WordPress site with unlimited runs, so a busy season of quotes does not change what you pay.
Common questions
How do I post ArcSite proposal approvals to Slack?
Connect Slack in FlowMattic, start a workflow with the ArcSite Proposal Approved trigger and add Send Channel Message. Map the customer, project and total into the text, approve a test proposal and switch it on.
What is the difference between Proposal Approved and Proposal PDF Signed?
They are separate ArcSite events. Use Proposal Approved to celebrate the decision and Proposal PDF Signed when your process needs the signed document before work is scheduled. Each can start its own workflow.
Can the rep who sent the proposal get the alert instead of a channel?
Yes, when the proposal data includes the rep's email. Find User by Email looks them up in Slack and Send Direct Message sends it to them.
Can I invite the install crew to the new job channel?
Yes. After Create Channel, add Invite User To Channel for each crew lead. The Slack account you connected has to be a member of the channel to invite people, which it is when it created the channel.
