"Vibras is the gap between contractors and
homeowners. Striving to build transparency
and seamless communication."
This brief translated into three non-negotiable product pillars: a contractor-side CRM powerful enough to replace generic tools, a homeowner portal that makes proposals comparable, and an automation layer that removes manual follow-ups.

HOW WE BUILT IT
A Milestone-Driven, Founder-in-the-Loop Build Process
When Vibras’s founder first reached out, we didn’t start with a proposal template. We ran a structured intake to understand what a contractor business needs from a tool that has to serve both contractors and homeowners. Below is the sequence we ran.
01 DISCOVERY
Mapped the full dual-user ecosystem. Clarified ambiguities on auth, subscription plans, coupon logic, and integrations.
02 WIREFRAMING
Produced low-fidelity wireframes for all 8+ milestones: auth, org management, proposal templates,
pipelines, customer management, drips, tasks, and team management.
03 UI DESIGN
High-fidelity Figma designs across Dashboard, Mobile App, CRM pages, HomeOwner AI, PDF layouts.
Full responsive spec delivered.
04 FRONTEND DEV
React implementation of all screens: pipelines, calendar, proposals editor, invoice module.
Unit + regression + compatibility tested.
05 API DEVELOPMENT
Node.js REST APIs for every feature area: leads, jobs, appointments, tasks, sequences, invoices, and payments.
With full API test coverage.
06 BACKEND
Authorize.Net payment gateway with AFDS. AWS SES + Pinpoint for email/SMS. QuickBooks sync.
Recurring billing engine with proration logic.
07 MOBILE APP
Android & iOS builds with feature parity to the web CRM. Contractor-focused mobile flows.
Job scheduling, task management, client communication.
08 QA & SANITY
Functional, regression, responsive, and compatibility testing across all milestones.
Sanity testing round post-integration before client handoff.
Authentication & Registration
The entry point to every contractor practice. Full registration flow capturing business name, industry, employee count, and referral source. Email verification sends the user to login after confirmation.
Three-Tier Dashboard System
Each user tier sees a different world. The Super Admin tracks all organisations. The Organisation Admin gets a live view of jobs in the next 1 to 90 days. The Contractor sees only their own calendar and tasks.
Sales Pipeline & Jobs Pipeline
Kanban-style dual pipeline: Sales Pipeline moves leads from Cold to Won/Lost. Jobs Pipeline tracks Project Accepted to Complete. Each stage change fires the configured email/SMS sequence automatically.
Fully Customisable Proposals
Proposal builder with background image selection, line item library, and per-job customer metadata stamped automatically. The homeowner receives a portal link to accept, reject, or compare proposals side-by-side.
Appointment Requests & Job Scheduling
Two scheduling paths: admin/salesperson-initiated and customer-initiated from the homeowner portal. Custom questions are admin-configurable. Job scheduling assigns crew, dates, and sends SMS confirmation.
Automated Sequences & Notification Engine
Admin-built sequences per lead stage with configurable sort order, email/SMS type, send timing, and per-notification active toggle. If a lead changes stage mid-sequence, all pending notifications for the old stage are discarded.
Task Management: Three Entry Points
Tasks are created from three separate surfaces: global nav, contact details page, and inside pipeline card detail views. All sync to the same underlying task record. Copy-from-template functionality lets team members clone tasks.
Team Management & Subscription Billing
CRM Admins add team members through a create form that triggers an Authorize.Net subscription payment. The system prorates the first charge. From the second month, costs consolidate into a single invoice.
Invoice Module & Payment Gateway
Invoices are created from completed jobs and include line items, deposits taken, and amount due. Authorize.Net handles one-time and recurring payments. Primary and secondary card management with auto-fallback email alerts.
Android & iOS Mobile App
Native mobile builds for contractors in the field. Feature parity with the web CRM on core flows: job calendar, task management, client communication, and invoice viewing. Push notifications via AWS Pinpoint.
WHAT TO EXPECT FROM US
Transparent Engineering and Predictable Delivery for Construction-Tech Products
If you are building a construction-tech, field service, or contractor-facing product and you are weighing agencies, here is what working with our team actually looks like, in plain language.
A plan before a proposal.
We start with a working session to understand what your product needs to do, who it serves, and where the hard parts are. You leave with a delivery plan, not a sales pitch.
A live demo every two weeks.
At the end of every sprint, you see the actual product: what’s built, what’s working, and what we’re still figuring out. You always know where your product stands. No month-long silences followed by a surprise reveal.
One team, all your platforms.
You get a single team handling iOS, Android, and web together. You don’t pay for three separate teams that don’t talk to each other, and you don’t end up with three slightly different apps that feel like different products.
Experience with the hard parts.
Contractor billing logic, payment gateways, role-based permissions, automated notification sequences. We’ve shipped these into production for real businesses. They’re not research projects for us, which means you skip a year of trial and error.
Quality that does not depend on one person.
Every change is tested automatically before it reaches you. Every release is reviewed by QA, by your team, and by us together. Nothing ships because one engineer said it was fine.
Security built in from day one.
Your contractors’ client data and payment records are encrypted, access-controlled, and audited from the first line of code. Protection is built in from day one, not a checklist at the end.
You own what we build.
At handover, you get the full product: the code, the documentation, the access keys, the operational guides. Your team can take it forward on their own, or keep us on, your choice, not a lock-in.
We tell you when the scope needs to grow.
When analysis reveals something not in the original spec, we flag it, explain the impact, and scope it as a change request. No hidden work.
