The Bottleneck in Your Business
You're on the third floor checking drywall seams when your phone lights up. The electrician's sub needs to confirm the rough-in schedule for Friday. Your lumber supplier is waiting on a revised quantity for the kitchen cabinetry order. Your project manager texts that the tile sub is two days behind and needs a revised milestone date. Meanwhile, the client just emailed asking whether the new countertop order is confirmed.
You're the single point of coordination for every sub, vendor, and material order on the job. Every phone call, every text, every "can you confirm the delivery date?" pulls you off the site and into a scheduling conversation that your crew doesn't need you for. The work isn't hard—confirming a delivery, adjusting a milestone, reordering a material—but it's fragmented across calls, texts, emails, and a spreadsheet that only you keep current.
PLMBR's AI office manager, Felicity, is built to handle that coordination layer. She runs the whole project—schedules, milestones, change orders, budgets, and margins—coordinating your subs, vendors, and office admins across every active job PLMBR for contractors. You approve what matters; she handles the rest inside PLMBR.
How PLMBR AI Agents Help with This Workflow
Felicity operates as the project manager and office coordinator for your contracting firm. Here is what the documented workflow covers:
- She runs the whole project. Schedules, milestones, change orders, budgets, and margins—she coordinates your subs, vendors, and office admins and stays on top of every job PLMBR for contractors.
- She orders materials from your supplier accounts. While she builds the estimate, she can place material orders from your own supplier accounts, on her own or with one-button approval PLMBR for contractors.
- You direct her in plain language. Talk to Felicity in the app or over email. Ask for a revised milestone, a vendor confirmation, or a material reorder, and she takes the action inside PLMBR PLMBR for contractors.
- Everything syncs to QuickBooks. Every job, expense, and invoice flows into QuickBooks automatically, so your books stay current without manual entry PLMBR for contractors.
- You approve every send. She drafts and queues; nothing reaches a client and no invoice moves until you tap approve PLMBR for contractors.
The pattern is consistent: Felicity coordinates, drafts, and queues. You review and approve. Your crew keeps building.
The Business Inputs and Existing Tools to Discuss During Onboarding
For Felicity to coordinate your subs and vendors effectively, she needs visibility into your project structure and supplier relationships. During onboarding, plan to walk through:
- Your active project schedules and milestones. Felicity coordinates subs and vendors against the schedule you already run, so having current milestone dates and sub assignments available helps her track progress PLMBR for contractors.
- Your supplier accounts. Material orders flow through your existing supplier relationships. Felicity can place orders from those accounts, on her own or with one-button approval PLMBR for contractors.
- Your QuickBooks file. Every job, expense, and invoice syncs automatically, so material purchases and sub invoices land in your books without manual entry PLMBR for contractors.
- Your Gmail and Google Calendar. Client conversations and scheduling tie into the tools you already use PLMBR for contractors.
- Your cost codes and markup structure. Felicity builds proposals and estimates using your cost codes and markup, so having those defined helps her keep budget numbers consistent across the project PLMBR for contractors.
You keep QuickBooks, Gmail, and Google Calendar. PLMBR handles the coordination work between them PLMBR for contractors.
Workflow at a Glance
| Task | Documented Agent Capability | Office Decision or Demo Question |
|---|---|---|
| Electrician sub needs to confirm Friday's rough-in schedule | Felicity coordinates subs, vendors, and office admins across the project schedule and milestones PLMBR for contractors | Ask in the demo: How does Felicity confirm the sub's availability and update the milestone if the date shifts? |
| Lumber supplier needs a revised quantity for cabinetry | She can order materials from your own supplier accounts, on her own or with one-button approval PLMBR for contractors | Ask in the demo: What does the one-button approval look like for a revised material order? |
| Tile sub is two days behind; milestone needs adjusting | She runs schedules, milestones, and change orders across the project PLMBR for contractors | Ask in the demo: How does a revised milestone propagate to dependent tasks and the client's status update? |
| Client emails asking if the countertop order is confirmed | She keeps every client posted on where their job stands, drafting the update in your voice PLMBR for contractors | Ask in the demo: Can I see the drafted client update in the approval queue before it sends? |
| You need to redirect a vendor mid-conversation | Talk to Felicity in plain language, in the app or over email, and she takes the action inside PLMBR PLMBR for contractors | Ask in the demo: If I text "hold the tile order until I confirm the layout with the client," does she pause that action? |

Owner Review, Exceptions, and Human Takeover
The approval gate is the default state. Felicity drafts and queues; nothing goes out under your name until you tap approve PLMBR for contractors. For material orders specifically, she can act on her own or wait for one-button approval, depending on how you configure the workflow PLMBR for contractors.
Your options on each queued item:
- Approve. The drafted message, order, or schedule change goes through as-is.
- Edit. You open the draft, adjust a quantity, reword a vendor note, or shift a milestone date, then approve.
- Reject. You discard the draft and handle the coordination yourself, or give Felicity new instructions to re-draft.
For exceptions—say a sub calls and says they can't make Friday, or a supplier flags a backorder on the countertop—you can direct Felicity in plain language to hold, revise, or escalate the item. The source confirms you can ask for anything and she takes the action for you, right inside PLMBR PLMBR for contractors. We recommend confirming in a demo how you'd handle a vendor backorder that cascades into a milestone shift, and whether a project manager on your team can access the same coordination queue.
An Illustrative Job: What to Test in a Demo
The following is a demonstration scenario for evaluation purposes, not a customer case study. Use it as a checklist when you sit down with our team.
Customer inputs for the demo:
- A kitchen remodel in progress, with cost codes for cabinetry, countertops, electrical, plumbing, and tile.
- The electrical rough-in is scheduled for Friday; the tile sub is two days behind on the first-floor install.
- The countertop supplier has flagged a two-week backorder on the quartz slab.
- The client has emailed: "Is the countertop still on track? Also, can we add a second outlet by the island?"
Questions to test in the walkthrough:
- Does Felicity draft a revised milestone for the tile sub and flag the downstream impact on the countertop install?
- Does she draft a client update explaining the backorder and the revised timeline, queued for your approval?
- Does the second-outlet request trigger a cost-coded line item using your markup, or does she flag it for your scope decision?
- Can you edit the drafted client update—adjusting the tone or adding a specific date—before approving?
- After you approve the revised milestone, does the schedule update reflect in the project view and sync the associated expense to QuickBooks?
These are questions to verify in a live walkthrough, not assertions about how the product behaves.
How to Evaluate This Workflow
Does Felicity's coordination match how your office actually runs subs and vendors?
The documented capability is that she coordinates your subs, vendors, and office admins and stays on top of every job PLMBR for contractors. If your office uses a project manager or superintendent who also tracks sub schedules, ask in the demo whether that person can see and act on the same coordination queue.
How does the material-order approval work in practice?
The source states she can order materials from your own supplier accounts, on her own or with one-button approval PLMBR for contractors. Bring a sample supplier order to the demo and ask to see the one-button approval flow for a revised quantity.
What happens when a vendor backorder cascades into a schedule shift?
She runs schedules, milestones, and change orders across the project PLMBR for contractors. Ask in the demo: when a backorder pushes a milestone, does Felicity draft the revised schedule and the client notification together, or do you handle those as separate approvals?
Can you redirect a coordination action mid-conversation?
The documentation confirms you can talk to Felicity in plain language, in the app or over email, and she takes the action inside PLMBR PLMBR for contractors. For a scenario where you need to hold a vendor order until a client confirms a layout, ask in the demo whether she pauses the queued action and holds it until you release it.
