Keep construction purchases understandable for your accountant

Prepare contractor receipts with job context, material purchases, supplier copies, and year-end exports. Separate document organization from project accounting.

A construction purchase can be straightforward at the counter and difficult to explain six months later. A receipt may include materials for two jobs, a tool for general use, and a returned item credited on another day. The accountant needs the original evidence and enough job context to ask the right questions. Just Invoice lets you capture that receipt from your phone, add the actual purchase date, and keep it available alongside the invoices you issue to customers.

Capture the receipt before leaving the supplier

Lay the paper flat and photograph the whole document, including the supplier details and any tax breakdown. For a long receipt, check that small print remains readable before you put it away. If the supplier provides a PDF, use that source file rather than a screenshot of one corner. The phone capture guide explains a simple quality check. Uploading is separate from creating an invoice; buying materials should not create a customer sales invoice by accident.

Add a job reference that will still make sense later

Use a short description such as “kitchen renovation, job J24, cabinet hardware.” A stable job reference is often more useful than a vague note like “supplies.” Avoid adding customer door codes, private phone numbers, or unnecessary personal details. If the purchase is general equipment rather than materials for one job, say that plainly. Descriptions make retrieval easier, but they do not create a project-costing ledger or decide whether the item should be treated as an expense or asset.

Explain split purchases and returns

Keep the complete source document when one receipt covers several jobs or includes personal items. List the relevant item groups in the description or your agreed handoff notes without altering the image. For a later return, preserve the correction document and reference the original purchase. The mixed-receipt guide helps you describe ambiguity. Do not invent an allocation simply because the accountant needs a number; identifying the uncertain items is a useful first step.

Bring sales and purchase evidence together

At review time, the accountant can inspect your customer invoice PDFs and purchase receipts through accepted access. Explain separately which materials were charged to a customer and which costs were paid by the business. The stored documents do not automatically establish a job’s profitability. Contracts, subcontractor records, payroll, banking information, and work performed outside Just Invoice may also matter. Ask which additional records the accountant wants rather than assuming the receipt archive covers the entire construction business.

Retrieve the year without losing late uploads

Use actual purchase dates for receipts added after the busy season. A December supplier purchase uploaded in February still belongs to the December purchase year when dated correctly. Prepare the year-end package, with separate questions for missing supplier documents and unresolved customer payments. For work that moves between sites, the mobile trades routine helps prevent paper from accumulating in the vehicle. Made in Canada, Just Invoice keeps capture approachable while leaving construction accounting and tax decisions with your professional adviser.

Can receipt descriptions produce automatic job-cost reports?

No. They help identify and retrieve source documents. A complete job-costing analysis needs other records and an appropriate accounting process.

Should I upload a subcontractor invoice as a purchase document?

A supplier document received by your business belongs with purchase evidence. Preserve the complete source and provide the additional context your accountant requests.
