SaaS Development FAQ

Common questions about hiring CANVERSI to design, build, and operate your SaaS product.

What SaaS apps has CANVERSI built?

Our flagship SaaS product is PixandFlow, an AI-powered banner ad generation platform built with Next.js, AWS Amplify, and Stripe. It serves thousands of marketers worldwide, generating professional banners in 20+ standard sizes from a simple text description.

What technologies do you use for SaaS development?

Our default SaaS stack is Next.js for the frontend, AWS Amplify for serverless backend infrastructure (Cognito auth, AppSync/REST APIs, Lambda, S3, hosting, CI/CD), and Stripe for subscription billing and pay-as-you-go credits. We integrate AI providers like OpenAI, Anthropic, and AWS Bedrock for AI-first features.

Can you integrate Stripe for subscription billing?

Yes. We have production experience integrating Stripe Subscriptions, Stripe Checkout, customer portals, metered billing, pay-as-you-go credits, webhooks, tax automation, and dunning. PixandFlow uses Stripe end-to-end for both monthly subscriptions and on-demand credit packs.

Do you build AI-powered SaaS products?

Absolutely. We design and build AI-first SaaS products that wrap large language models, image generation, and custom ML pipelines into polished commercial products with billing, multi-tenant access controls, prompt orchestration, and observability.

How long does it take to build an MVP SaaS?

Most MVP SaaS projects ship in 6–12 weeks. We start with a fixed-scope discovery, build authentication, billing, and the core feature set on Next.js + AWS Amplify, then iterate post-launch based on real user feedback.

Do you handle hosting, deployment, and scaling?

Yes. We deploy on AWS Amplify Hosting with automatic CI/CD from Git, Lambda functions for backend logic, DynamoDB or Aurora for data, CloudFront for CDN, and Cognito for auth. Everything autoscales to handle traffic spikes without ops headaches.

Have a SaaS Idea?

From MVP to enterprise, we build cloud-native SaaS products that ship fast and scale predictably. We usually reply within one business day.
