What this project was for

ClientAndrey — owner/operator
EngagementBuilt from scratch · team 3–5
RelationshipMulti-year, ongoing

Replaced five disconnected tools — repair tickets, POS, inventory, marketing, Amazon compliance — with one system on a single data model. Runs the shop day to day, with live daily vendor sync and MAP/3P Amazon compliance.

The problem

The problem

Andrey ran a real retail and repair business on tools that didn't talk to each other — repair tickets in one place, POS in another, inventory elsewhere, email marketing in a fourth, and Amazon reseller pricing rules tracked by hand. His online presence was a brochure website, useless for running anything. Nothing shared a single source of truth, so every number had to be reconciled by hand.

He didn't need another tool. He needed the five he had to become one.
What we built

What we built

01

Repair tickets & POS

the operational core — full ticket lifecycle with payment status, deposits, mechanic assignment, special-order flags, and a scheduled/overdue view; in-store checkout with UPC scanning, custom line items, auto tax, and Stripe cash/card/split — feeding the same sales ledger as repairs.

02

Inventory & wholesale in one catalog

barcode-driven part catalog with per-item audit history, inter-location transfer, bulk import, multi-warehouse; one source of truth powering POS and marketing.

03

Customer CRM + bulk email

auto-built customer database deduped by email, aggregating every ticket; campaigns built straight from products and customers.

04

Amazon reseller compliance

3P-restriction and MAP (Minimum Advertised Price) management most shop software simply doesn't have, wired into the same inventory and pricing data.

05

One command center across branches

net-sales/orders/repairs dashboard by week/month/year, sales ledger by branch and mechanic, staff time tracking, and a Super Admin layer with role-based permissions.

Built to run in production

Built to run in production

Five tools, one data model

unifying CRM, email, tickets, wholesale, and POS so they share one data model was the hard engineering.

Multi-branch, multi-role, granular access

one system models a real operation; each role sees exactly the right slice, scaling from one shop to several.

Inventory that updates itself

scheduled Celery tasks pull live data from multiple vendors every single day; the foundation the MAP compliance depends on.

Results

Results

5-in-1

Five separate tools collapsed into one system on a single data model.

Daily

Live multi-vendor inventory sync runs every single day.

Hundreds

Real repair tickets processed through the platform.

Multi-year

Still built and extended as an extension of the owner's team.

Architecture & technical approach

How it was built

The hard engineering here was unification, not features: repair tickets, POS, inventory, wholesale, CRM, and email marketing were rebuilt onto a single shared data model, so every number reconciles itself instead of being re-keyed across five disconnected tools.

The system models a real multi-branch operation. Branch- and role-scoped access, with a Super Admin layer on top, means each role sees exactly the right slice — and the same model scales from one shop to several without a rewrite.

Inventory stays current on its own: scheduled Celery tasks pull live data from multiple vendors every day. That daily pipeline is also the foundation the Amazon MAP (Minimum Advertised Price) and 3P-restriction compliance logic depends on.

One data model, five tools

CRM, email, tickets, wholesale, and POS share a single source of truth.

Multi-branch, multi-role access

Role-scoped permissions and a Super Admin layer model a real operation across locations.

Self-updating inventory

Scheduled Celery jobs pull live multi-vendor data every day.

Amazon MAP / 3P compliance

Pricing-rule enforcement wired into the same inventory and pricing data.
