Your team is running a business process on a spreadsheet. That breaks at scale — every time.
When a business process outgrows its spreadsheet — multiple users editing simultaneously, workflow logic too complex for formulas, external users who need controlled access — we build the web application that replaces it. Fixed scope, fixed price.
The spreadsheet that ran your business process at 10 transactions per day can't handle 100. Multiple people are editing simultaneously and overwriting each other. External users can't access it safely. Every calculation is a formula that someone accidentally deletes.
Spreadsheets are extraordinarily capable tools for single-user, sequential workflows. They're the wrong tool the moment a workflow requires multiple users with different permission levels, real-time data visibility across the team, complex business logic that gets encoded in increasingly fragile formula chains, or external access from customers, partners, or suppliers who shouldn't have visibility into your entire spreadsheet.
Most spreadsheet-managed workflows break in the same ways. Version control collapses when multiple team members save their own copies and someone loses track of which is current. Simultaneous editing causes data overwrites — two people update the same row at the same time, one update disappears. Formula logic accumulates technical debt until the spreadsheet breaks and nobody is confident enough to fix it. External sharing requires giving an outsider access to more data than they should see.
The interesting thing about spreadsheet workflows is that they're usually well-understood. The person who built the spreadsheet knows exactly what the workflow does, what data it tracks, and what the rules are. That clarity is actually the input we need to build the web application — the spreadsheet is the specification.
A web application that replaces the spreadsheet — multi-user, role-based access, automated workflow logic, external user access, and an audit trail — built on a real database that doesn't break when two people edit at the same time.
Data model from your spreadsheet structure
Your spreadsheet tabs become database tables. Column headers become fields with the correct data types — numbers, dates, dropdown values, relationships to other tables. The data integrity that formulas could never guarantee.
Multi-user access with roles
Different team members get different access — some can edit, some can view, some can approve, some can export. External users (customers, suppliers) get access to only their own records. Row-level security enforced at the database level, not by hiding columns.
Workflow automation
The manual steps in your spreadsheet process — updating a status column, notifying someone, moving a row to another tab — become automated triggers. Status changes send notifications. Approvals move records through defined stages. Nothing gets missed because nobody remembered to update a cell.
Audit trail
Every change logged with the user who made it, what they changed, and when. The accountability that a spreadsheet can never provide.
Reporting and export
Summary views, charts, and data exports that produce the reports you currently build by manually aggregating spreadsheet data. Built on Next.js, Postgres, Clerk authentication, TypeScript.
One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Spreadsheet-to-web-app projects are well-scoped — the spreadsheet is the specification, the workflow is documented in the formula logic, and the requirements are understood. Fixed scope, fixed price fits this project type exactly.

Questions, answered.
We plan a parallel-run period during the build — typically the last 2 weeks before full cutover. The new app is in production with real data, the team uses it alongside the spreadsheet, and any discrepancies are resolved before the spreadsheet is retired. The parallel run reduces the risk of cutover.
Yes — existing spreadsheet data is imported into the new application's database during the migration. We clean and normalise the data during import (standardising formats, resolving duplicates, fixing inconsistencies) so the application starts with clean data.
We review the formula logic during scoping. Some formulas translate directly to database calculations. Others require workflow logic that needs design discussion. We document the business rules in plain language during scoping so we agree on the logic before building.
External user portals are a standard feature of spreadsheet replacement apps — customer-facing views, vendor portals, or partner dashboards that give external parties controlled access to their own data. This is a common scope addition to the core web application.
A spreadsheet workflow replacement with multi-user access, role-based permissions, workflow automation, and reporting typically runs $25k–$55k. External user portals and integration with other systems add scope. Fixed-price.
