Q1 ARR unlocked · multi-tenant SaaS shipped in 87 days for $28k fixed
“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.”

CEO, BridgeOps
The wrong web stack costs you a year. Slow rebuilds, missed deadlines, freelancer drama, and a codebase your next engineer doesn't want to touch. We've seen this story end the same way dozens of times — and we built Paisol so it stops.
We're a senior-only Next.js and React team shipping production web apps since 2020. From a focused MVP that proves the idea, to a multi-tenant SaaS with Stripe billing and SSO, to a B2B portal that integrates with Salesforce and your data warehouse — we ship the code, you own everything from day one. Our AI engineers can also weave LLM features into your app, and our BI team handles the analytics layer.

Is this web build right for you?
A blunt check before you book a call.
This is for you if…

- You've validated user demand or have LOIs
- You want fixed price quoted in writing within 48 hours

This is NOT for you if…
- Budget is < $10k — consider a freelancer or no-code
- You can't describe the product in one sentence
- You expect to change scope every week
- You want hourly billing or unlimited revisions

The questions we get on every first call — answered.
- A fixed-price MVP runs $12,000–$45,000. A polished v1 of a SaaS product (auth, billing, dashboard, public marketing site, basic API) is typically $24,000–$60,000. Enterprise B2B portals with custom integrations and role-based access can run $60,000–$200,000. We quote a fixed price in writing within 48 hours of your strategy call.
- 90 days for an MVP, 4–6 months for a polished v1. If your timeline is shorter than that, we'll re-scope rather than promise something we can't ship. We'd rather phase it than miss the deadline.
- Next.js for SaaS apps, dashboards, B2B portals — anything authenticated and dynamic. Astro for marketing sites and content-heavy sites where SEO is the goal. Remix when you need very fine-grained data loading control. We'll recommend the right one on the strategy call.
- You do. 100%. Source code, GitHub access, deployment access, environment variables, and full documentation are transferred to you from Day 1. No vendor lock-in. We do not hold your code hostage.
- Yes. We do code rescues. We've rebuilt 30+ projects that other teams left half-finished. We'll audit your repo, give you a written rebuild-vs-fix recommendation, then ship.
- Yes — both are non-negotiable in everything we build. Every site we ship hits Core Web Vitals (LCP, INP, CLS) at "good" or better, has full structured data, and is set up for Google Search Console from day one.
- Cheap is the most expensive thing you can buy in software. Our senior-only model means it's right the first time — saving you the $40k–$120k rebuild that most founders learn about the hard way. Read our guide on red flags when hiring an agency.
