One system. Dave does the work.
Payaca is the CRM, project management and field service system for growing US solar installers. Run the whole job in one place, from quote and permit to crews, costs and final payment. Agent Dave, the AI built in, writes your reports, builds your automations and drafts your documents.
The CRM, the project management and the field service system, in one.
Every part of the job lives on one record, so nothing is retyped and nothing is lost between the office and the van.
CRM and pipeline
Inquiries, customers, deals and the stages your jobs move through.
Proposals and quoting
Priced proposals the customer signs online, with deposits where they apply.
Scheduling and the field app
Crews booked, site surveys captured, documents signed on site, offline if it has to be.
Compliance
Permit applications and inspection records from the job itself.
Design
Glow for solar design, in limited release, or import from OpenSolar.
Costs, invoicing and payments
Job costs while the work is live, invoices from the proposal, payment in the customer portal.
Deeper in the system
Stock and purchase orders
Bulk-bought kit held in named locations at real cost, and purchase orders raised from the job's materials list.
Purchase orders
Sent to the supplier from the project, confirmed against what arrives.
Customer portal
The customer sees the estimate, the proposal to accept, bookings, invoices and documents under your brand.
The AI assistant that does the work
Dave is not a chatbot pointing at help articles. He connects to your Payaca data and takes real action on it.
He builds your automations
"Chase quotes that go quiet after two weeks." Dave works out the trigger, conditions and actions and creates it switched off for you to check. You turn it on. When the work repeats, the automation runs it - Dave builds it.
He writes your documents
Describe the handover pack, commissioning certificate or service report - Dave builds it live, in your branding, with your fields. No coding, no template agency.
He answers the hard questions
"Where are we losing jobs?" Conversion by stage, unpaid invoices, margin per job, which engineer is busiest - Dave works it out from your data and shows you the numbers.
He connects to your other tools
The MCP server exposes your Payaca data to any AI tool or agent framework you already use - inside your permissions, never outside them.
Real people too. Dave answers in seconds, and our support team is there whenever you'd rather talk to a human.
More installs expose the gaps between your tools.
When each team has its own spreadsheet
- A design becomes a quote, then someone has to enter the details again.
- The office chases the latest survey notes before booking the install.
- Permit applications and AHJ inspection documents end up in another folder.
- Job costs are hard to see while the work is still underway.
When your CRM, quoting and scheduling tools are separate
- The accepted proposal doesn't carry through to the job plan.
- The finished roof design lives in your design tool - the quote is rebuilt in the CRM, and the materials list is retyped again.
- Paperwork and payment get chased after the team has moved on.
- Managers need to check several systems to see where a job stands.
Keep the detail with the job as work moves forward.
The office and field team can work from the same project, with proposals, schedules, documents, costs and invoices linked to it.
The design and the job are the same project
Stop copying between your design tool and your quoting software. Design in Payaca, or keep the tool you already use - either way, the design flows into the quote, the materials and the job.
Solar design
Glow
Design the roof where you run the job
Pin the roof and Glow pulls high-resolution imagery, finds the roof faces and lays the panels out from your own catalogue. The estimate carries the production figures worked from the orientation, pitch and shading of the actual roof - and the kit becomes the priced items on the proposal, then the materials list, then the purchase orders. The margin on the job is live from the day it's quoted.

One system behind the work
Solar, heat pumps, batteries, EV charging. Payaca runs the quoting, scheduling, compliance and payments behind every install, so your team can stay on the tools.

Sales pipeline and CRM
Everything a CRM does, and everything it doesn't
Most CRMs were built for software companies, not installers. Payaca's CRM is built around the install lifecycle: quoting, scheduling, compliance, invoicing. Your pipeline reflects how the work actually flows.
Pipeline that knows your installation lifecycle
Visual stages from first enquiry to commissioned install. Drag and drop, see values per stage, automate follow-ups.
Email and customer history in one place
Forward inbound emails or BCC outbound. Every conversation logs against the right project so the whole team sees it.
