Practical Guide to Managing Contractor Expenses in Belgium

Why a systematic approach matters

Contractors frequently purchase small items—materials, fuel, tools, meals—that generate receipts. Keeping these documents readable and organized helps you claim deductible expenses and makes the accountant’s work easier.

Capture receipts at the point of purchase

• Use a smartphone to take a clear photo of each receipt immediately after the purchase.
• Store the image in a dedicated folder or an expense‑tracking app.
• Verify that the photo shows the date, total amount, VAT amount or rate, supplier name and a brief description of the purchase.

Digital copies are accepted by the Belgian tax administration as long as they are legible and contain the required information.

Organise expenses by project or category

1. Project‑based tracking – Assign costs to the specific construction site or project (e.g., cement for the “Kerkstraat” site). This gives you a realistic view of each project’s profitability.
2. General expenses – Items that are not linked to a single project (office supplies, phone subscriptions, insurance) should be recorded under a “General” category.

Create a simple list of categories that matches your business, for example:

• Materials
• Fuel
• Tools
• Sub‑contractors
• Insurance
• Office & administration
• Vehicle & transport
• Communication

Information your accountant needs

For every receipt or invoice, provide:

• Date of purchase
• Total amount (including and excluding VAT)
• VAT amount and applicable rate
• Supplier name
• Short description or chosen category

If this data is entered when you capture the document, the accountant can import the files directly, reducing manual entry.

Using software to extract data automatically

Many expense‑management tools can read key fields from a receipt image (date, amount, supplier, VAT). A typical workflow is:

1. Scan the receipt with the app.
2. Let the software extract the data.
3. Review and correct any errors.
4. Assign the receipt to a project or category.

Accuracy depends on the quality of the original receipt; poorly printed or damaged documents may still require manual correction.

Handling supplier invoices

Supplier invoices (e.g., from building‑material distributors or insurers) usually arrive as PDFs or paper copies. Apply the same steps:

• Scan or upload the invoice.
• Extract the required data.
• Link the invoice to the relevant project or to general expenses.

Quarterly overview and reporting

At the end of each quarter, generate a summary that shows:

• Total spend per category
• Total spend per project
• Overall expenses

This overview supports your VAT return and provides internal insight into cost distribution. For the current VAT rules, consult the Belgian VAT portal and verify your specific situation.

Checklist to get started

• Install a reliable scanning app on your phone.
• Define the project and category structure that fits your business.
• Scan each receipt or invoice immediately and enter the required details.
• Review extracted data weekly for accuracy.
• Produce a quarterly summary and share it with your accountant.

By making scanning a habit, you reduce the risk of lost or illegible receipts and streamline the accounting process.
