A large system for Indigo Luxor. Three interconnected applications cover the whole chain from field sales to bookkeeping: a PWA for field salespeople, a complete back-office dashboard with 8 separate modules, server-generated PDF documents. Bookkeeping no longer types documents — it reviews them.
The story
What 750 documents a day actually cost — and what happens when you replace them with a system that covers the full chain, from sale to bookkeeping.
Worth noting
Salespeople made sales on paper. The supervisor forwarded the paper to bookkeeping. Bookkeeping retyped every document into a formal invoice and dispatch note. Roughly 50 salespeople at about 5 sales a day means around 750 documents a day going through manual re-entry. Growth of the sales team meant proportional growth of the back office. Indigo Distribution wanted to move from a regime where the number of typists limits sales growth to a regime where software does that job.
We developed a system of three interconnected applications and one backend. The field app for salespeople is a Next.js PWA optimized for the phone — it doesn't require installation, runs from the browser — with modules for customers, documents (new and existing), warehouse (stock and cards), and profile. The central back-office dashboard covers the whole chain across eight separate domains: overview, organization and companies, customers with locations, sales (invoices, dispatch notes, delivery notes, credit notes, return notes), catalog (items, prices, types, units, tax rates), warehouse (storage, transfers, adjustments, goods receipts), finance (customer payments and salesperson payouts with commissions), bookkeeping, and personnel. The backend is in .NET as a modular monolith with a separate test suite for PDF document generation — invoices and dispatch notes don't arise from typing in Word; they're generated server-side from the database, with the same structure every time.
Modules & surfaces
We mapped the existing processes — every form, every handoff, every signature — and modelled the document chain as a state machine in which every piece of paper has a clear life cycle. The field app was designed for one-handed use on a phone — salespeople aren't at desks. The back office was designed mostly for review, not entry — bookkeeping becomes a reviewer. We extracted PDF generation into a separate component with a dedicated test suite, because invoices and dispatch notes carry legal weight — they can't look different from version to version.
~750 documents a day no longer require manual typing. Bookkeeping moves from the role of typist to the role of reviewer — the same team can support a growing sales network. The full document chain becomes end-to-end auditable, with server-generated PDFs that always have the same structure.
