Free inventory software for construction and building suppliers

The short answer

• The trade pattern: stock lives in three places at once — warehouse, yard, job — and moves without a counter sale.
• The essentials: live stock per location, purchase orders tied to jobs or projects, and counts frequent enough to catch the drift.
• What a free download can be: a spreadsheet phase, honestly; the joined record — locations, projects, purchasing — is the paid product.
• BSimple runs the trade pattern — including reserving items to jobs — from $180/month (AUD) with a free trial.
• The wider system: inventory management end to end maps the whole record this page sits in.

Why construction stock breaks ordinary tools

Retail stock sells at a counter; construction stock moves to where the work is. A pallet of fixtures leaves the warehouse for a job site; a compressor rides a truck for a fortnight; a generator sits at a customer site for months. None of that is a sale, so channel-attached tools never see it — and a single spreadsheet cannot hold three locations plus three projects plus the trucks. The stockouts that follow are the peculiarly construction-flavoured kind: the crew waiting on a delivery that was in the yard all along.

The essentials follow. Live stock per location — warehouse, yard, vehicles, and job sites as places stock exists. Purchasing tied to demand — job needs becoming purchase orders, not phone calls. Counts on the move — the yard drifts more than any retail shelf, so counting must happen from a phone, in the mud, weekly. And project-level tracking — what went to which job, so the cost of a project includes the materials that never came back.

Where BSimple fits

We build BSimple, so weigh that. For builders and building suppliers it holds the whole pattern on one record: multi-location live stock (yard, warehouse, vans), batches where relevant, purchase orders from demand with supplier variance flags, stocktakes and counts from any phone browser, and the projects feature for the job side — reserve materials and equipment to a job without consuming stock, install and consume on invoice approval, and keep service and maintenance history per asset. Invoicing hands off to Xero or MYOB. Plans start at $180/month (AUD), and the free trial runs one real job through the loop.

The boundary, plainly: BSimple is not construction project-management software — no Gantt charts, no job costing ledgers, no subcontractor portals. It is the stock and materials record the projects depend on. For the wider construction-software picture, the construction management guide is the honest next read, and barcode scanning in inventory shows how the yard stays counted.
