How BridgeOps shipped a multi-tenant construction SaaS in 87 days and closed $340k ARR in Q1

The brief

BridgeOps is a Toronto-based construction operations platform serving mid-market commercial general contractors. They had a verbal handshake with a major Ontario GC for an enterprise contract — but the contract was contingent on a working product. Three months out from the renewal deadline, they had wireframes, ambition, and no working software.

They needed a senior web development team that could turn a vague concept into a multi-tenant SaaS with real billing, real auth, and four non-negotiable integrations — and ship it before the renewal expired.

The constraint

The deadline was hard: 90 days, no flex. The integrations were specific (Procore, Sage 300, DocuSign, QuickBooks Online), each with its own quirks and rate limits. And the contract required SSO via SAML from day one — not "coming soon".

BridgeOps had interviewed five agencies. Three quoted 6+ months. One quoted 4 months at $90,000+. The fifth quoted 12 weeks at $80,000 with hourly billing on top. Then they called us.

The scope we agreed to

$28,000 fixed-price. 12 weeks. SSO + 4 integrations + admin + Stripe billing + marketing site. Quoted on a Tuesday, signed on Friday, kickoff the next Monday.

What was in scope:

Next.js 14 multi-tenant SaaS with workspace-scoped auth
SAML SSO via Clerk Enterprise
Stripe subscriptions + invoice-based billing for enterprise plans
Role-based access control (admin, manager, field)
Procore, Sage 300, DocuSign, QuickBooks integrations
Admin dashboard with full audit logs
Marketing site + privacy/terms pages
Production deploy to BridgeOps' AWS account, full handover

What was out of scope (deferred to v1.1, written down):

Mobile app (later quoted separately for $35k)
White-label customer portal (later quoted at $18k)
Power BI embedded analytics (later quoted at $14k)

The architecture

We picked the boring stack on purpose. The contract didn't care about our tech choices — it cared about a working product. So we picked tools we've shipped 50+ times before:

Framework: Next.js 14 App Router
Auth: Clerk (with Enterprise SAML add-on)
DB: Neon Postgres with Prisma ORM, schema-per-tenant for isolation
Billing: Stripe subscriptions for SMB, manual-invoice for enterprise
Integrations: Inngest for async job orchestration with all 4 partners
Deployment: Vercel for marketing site, AWS Fargate for the app (per their contract requirement)
Observability: Sentry, Axiom, Vercel Analytics

The timeline — 87 days end-to-end

We promised 90 days. We shipped on day 87.

Day 1–5: Discovery, wireframes signed off, data model finalized
Day 6–25: Core platform — multi-tenant auth, RBAC, admin shell, first 2 integrations
Day 26–45: Stripe billing, SAML SSO, remaining 2 integrations
Day 46–60: Admin dashboard, audit logs, marketing site
Day 61–80: QA, security review, penetration test, load test
Day 81–87: Production deploy, knowledge transfer, contract demo

The result

BridgeOps demo'd the platform on day 89. The GC signed the renewal on day 96. $340,000 in Q1 ARR unlocked. 14 enterprise users in the first month. Zero critical bugs in the 90-day post-launch warranty window.

Over the following 4 months, BridgeOps came back for the deferred scope: mobile app, white-label portal, and embedded BI. Total Year-1 spend with Paisol: $95,000. Year-1 ARR they unlocked from the platform: ~$1.2M.

They quoted us a fixed price on a Tuesday. The MVP was live 87 days later. We've closed enterprise deals we wouldn't have qualified for without this product.

What we'd do differently next time

Push the QA window forward. Day 61–80 felt rushed. Next time we'd carve out QA as a parallel workstream from week 6, not a single block at the end.
Insist on staging-with-real-data earlier. The integration partners' sandbox APIs lie. We caught 3 production-breaking surprises in QA that we'd have caught a month earlier with a real-data staging environment.

Numbers for the math nerds

Build cost: $28,000 (fixed)
BridgeOps first-quarter ARR unlocked: $340,000
Q1 ROI: 12.1×
Year-1 ARR unlocked from the platform: ~$1.2M
Year-1 ROI on the build: 42×
