See it in action
Buy, quote, extend credit, deliver — with the numbers at hand
Products, customers and vendors each have a page with their stock, costs, prices, balances and trends. When you write an order, every price and each vendor's past costs open right beside the line. Today's delivery route sits on one map. A read-only copy of the real MasterQ screens — follow the ten steps, or click around.

Fulfillment
One order, handed over however the customer wants
A big order doesn't have to leave in one go. Some goes out the counter today, some is picked up over several visits, some ships to different addresses, the rest goes on your own truck — and MasterQ keeps track of every piece.
- Counter · Taken on the spotRing it up, take payment, hand it over.
- Will call · Picked up over several visitsSet the stock aside; the customer books a time to collect, as many times as they need. Every pickup is recorded.
- Ship · To more than one addressSend one order in several shipments, to different job sites if needed. Each shipment is tracked on its own.
- Delivery · On your own truckPlan runs and routes. At each stop the customer signs on an iPhone or iPad, the driver adds a photo — or records why the drop failed.
Today's work, on one screen
Open the warehouse and see every delivery, shipment and will call due today. A new pickup booking shows up the moment it's made, and when a customer signs on an iPhone or iPad, the order shows signed right away.
Your own MasterQ — not a shared one
Most online software runs every customer on one shared system and keeps them apart in code. Each MasterQ customer gets a system of their own.
Its own deployment and database
Your MasterQ runs on its own web app and its own database, apart from every other customer. Another customer's problem or busy day never reaches you. Or run it in your own shop.
Updated and tailored one customer at a time
We update each customer's system separately. What we build for you lives only in yours — nobody else's changes carry it off, and yours touch no one else.
Your data, and you can leave
Ownership is in the contract; export everything any time. Stop paying and MasterQ turns read-only, not locked. If we ever stop supporting it, you get the source code.
The price is in the contract
List price doesn't rise for 3 years, then by no more than 5% a year.
Simple, published pricing
One plan, plus the add-ons you need. Every price is on the page.
