About Orrin

Orrin is a platform for freelancers and independent specialists — developers, designers, marketers, video makers and copywriters alike. Instead of offers glued together in Word and mailed out as PDFs, users build a library of their services and assemble a complete, visually consistent offer from it: scope, portfolio, schedule and payment plan included. The client receives a link, reviews everything in the browser and accepts with one click.

About Personit

At Personit, we help startups and scaling businesses move from idea to real product — up to 5x faster than traditional dev teams. We specialize in low-code platforms and AI-powered development.

Challenge

Freelancers sell their work through offers — and those offers usually get written in Word, exported to PDF and lost in a client's inbox. Orrin needed a platform that would:

Turn writing an offer from an evening chore into a guided, few-minute process
Do the math for the freelancer — from hourly rate, hours booked and tax
Put the portfolio and scope of work in the same document as the price, not behind a separate link
Give clients easy access without creating an account or downloading attachments
Move questions and arrangements out of the email thread and next to the offer itself
Leave a clear record of the decision: who agreed to what, and when

Key Functionalities

A 7-step offer builder — from details to a ready-to-send summary

Reusable service library with work stages and deliverables

Net and gross amounts calculated automatically from rate and hours

Project schedule and staged payments (50/50, 20/40/40) with terms per instalment

Offer behind a password-protected link, valid 30 days — no client account needed

Comments on the offer plus accept or decline with an instant email notification

Why low-code + AI?

A platform with user accounts, portfolio files and public client access had to ship in two months — with no compromise on data security.

React & Supabase allowed us to:

Building the interface with ready-made React components instead of coding UI from scratch
Supabase as 'Backend-as-a-Service' – accounts, authentication and API access right out of the box
Postgres enforcing at the database level that a freelancer only ever sees their own offers and data
Storage for portfolio files and offer assets without building custom infrastructure
Edge Functions for password-protected links and transactional emails, with no servers to maintain
Security and scalability 'out-of-the-box', saving weeks of development work

The result: a complete offer platform built in a fraction of the time traditional development would take.

Low-Code Speed, Custom Code Quality

Rapid launch thanks to ready-made backend modules

Accounts and client access secured from day one

Every freelancer's data isolated at the database level

Modular architecture ready for the platform's next modules

Our team has delivered over 100+ production-grade apps using technologies such as React, FlutterFlow, Bubble, Supabase, Firebase and AI-enhanced tooling. That experience allows us to go fast without cutting corners – a key differentiator in the low-code space.

The Results

Freelancers send one consistent, complete offer instead of a document pieced together in Word

Clients open the offer in a browser — no account, no attachments, on any device

The decision comes only after the whole offer is reviewed — the platform tracks every section

Questions and arrangements happen next to the offer, not in a scattered email thread

A sent offer is frozen — later pricing changes never alter what the client received

Company details, services and portfolio are filled in once and reused in every offer that follows
