Custom inventory software
Custom inventory software is what you need when the way you actually move stock — serialised units, kits built from components, consignment sitting at a customer site, transfers between branches and job sites — is exactly the part no off-the-shelf product models. We build the system around that process instead of asking you to flatten it into someone else's fields. The AI builds it. A real person stays on your account until it matches how the warehouse really runs.
Your process, modelled properly. Live in days, not a six-figure project.
What custom inventory software actually means here
Most inventory products assume one shape: a SKU, a quantity, a warehouse. Real operations rarely look like that. A unit is serialised and still under warranty. A kit is assembled from six components that each carry their own stock. Half your stock is on consignment at a customer site and is still yours. A pallet is in transit between two branches and belongs to neither.
Custom means the data model starts from those facts. We define your units, your statuses and your movement rules — reserved, in transit, on consignment, at the job site — and build the screens your team uses around them. Nobody has to invent a workaround column called "notes" to hold the part of the process the software refused to understand.
If your stock really does fit a plain SKU-and-quantity table, you don't need custom — build a straightforward inventory app instead and be running the same afternoon.
Built on the inventory data you already have
Connect your SQL database
Read and write straight against Postgres, MySQL or SQL Server. Your ERP tables stay the source of truth.
Bring the spreadsheets in
The sheet where someone tracks serials by hand becomes a real table with validation — not a copy-paste step.
Sync instead of re-keying
Stock levels update from the systems that already hold them. Nobody retypes a count into a second place.
Keep your part numbers
Your SKUs, your naming, your units of measure. Nothing gets renamed to suit the tool.
Multi-location stock, transfers and job-site inventory
One number for on-hand and allocated stock across every branch, van, trailer and customer site — with the transfers between them recorded as movements rather than as a phone call somebody forgot to make.
Every location on one screen
Branches, warehouses, vans and job sites side by side, each with its own on-hand and reserved figures.
Transfers that stay accounted for
Stock in transit belongs to the transfer, not to either end, until somebody actually receives it.
Serial and lot level
Follow individual units and lots through every move, so "where is unit 4471" is a search, not three phone calls.
What a dev shop quotes you, and what this costs instead
A bespoke inventory system is usually quoted as a project: a discovery phase, a specification document, a fixed price in the tens of thousands, and a delivery date a quarter away. By the time it lands, the process has moved on and the change requests start.
Agent UI is a subscription, not a project. The plans are public — free to start, $25/month for Solo, $49.99 for Builder, team plans from $99.99 — and the first working version of your system gets built in days, in front of you, on your own data.
You keep it afterwards. Adding a status, a field or a whole new location is a conversation with the AI, not a change order and another invoice.
Roles and an audit trail on every stock movement
Role-based access
Warehouse staff count and pick. Supervisors adjust. Finance sees valuation. Nobody sees a location they don't run.
Every change on the record
Who adjusted the count, when, and from what to what. Shrinkage stops being a mystery nobody can reconstruct.
One shared source of truth
A real database instead of five versions of the same spreadsheet living in one email thread.
White-glove onboarding: we build the first version with you
Show us the process
One call, screen shared. Your current sheet, your ERP, and the exceptions everyone quietly works around.
We build it in front of you
Tables, screens and roles come out of that session, using sample rows from your own stock — not a demo catalogue.
It stays yours
Your team owns and edits it, so the system never becomes one person's fragile side project.
