Before You Hire a Bookkeeper: What Contractors Must Know

Outline Unicorn regularly connects with contractors who have tried bookkeeping on their own or worked with a generalist bookkeeper, only to discover that their records do not actually reflect how their business works.

Construction and trades bookkeeping is a specific discipline. Before you hand your books to anyone, there are a few things worth understanding so you can make the right call the first time.

Why General Bookkeeping Experience Is Not Enough for Contractors

Most bookkeepers are trained on standard small business accounting, which covers invoicing, expense tracking, bank reconciliation, and basic tax reporting. That skillset handles a retail store or consulting practice reasonably well. It does not handle a construction company the same way.

Contractors deal with financial structures that require specific knowledge and specific handling inside whatever accounting software is being used. Job costing, construction holdbacks, progress billing, and the distinction between materials, labour, and subcontractor costs all need to be tracked separately and accurately. When a bookkeeper does not understand these categories, they enter transactions in ways that look clean on the surface but produce reports that are useless for managing a project or preparing a tax return.

→ From a professional standpoint: A bookkeeper who cannot explain how holdbacks affect your accounts receivable balance is not the right fit for a construction business, regardless of their years of general experience.

What Should a Contractor Look for in a Bookkeeper in Canada?

The right bookkeeper for a contractor understands both the financial side of the business and the operational reality of how construction projects actually run. There are several specific things to look for.

• Job costing capability: They should be able to set up and maintain job-level cost tracking so you can see profitability per project, not just across your business as a whole.

• Holdback management: Construction contracts in Canada typically include a statutory holdback, often 10%, that cannot be released until specific conditions are met. Your bookkeeper needs to account for this properly in both your receivables and your cash flow reporting.

• Subcontractor T4A compliance: They need to know when T4As are required, how to track sub payments across the year, and how to file accurately by the February deadline.

• GST/HST on construction services: The tax treatment of construction services, new builds, renovations, and certain rebate scenarios is not identical. Your bookkeeper should be able to navigate these distinctions without guessing.

• Software proficiency: QuickBooks Online is the most commonly used platform for remote bookkeeping in Canada. If a bookkeeper is not proficient with it, your options for cloud access and remote collaboration are limited.

→ A quick tip to remember: Ask any prospective bookkeeper to describe how they handle holdbacks in QuickBooks. The answer will tell you quickly whether they have real construction experience or general bookkeeping experience rebranded as construction knowledge.

Red Flags to Watch for When Evaluating a Bookkeeper

Not every bookkeeper who says they work with contractors actually has the depth of experience the role requires. These are the warning signs worth paying attention to before you sign anything.

• Vague answers about job costing: If they cannot explain how they would set up cost codes for your projects or how they would separate labour from materials at the job level, they are not equipped for construction bookkeeping.

• No experience with CRA remittances: Bookkeepers working with contractors need to be familiar with GST/HST remittance schedules, payroll remittances, and subcontractor reporting requirements. Gaps here create real compliance risk.

• No mention of holdbacks: A bookkeeper who does not raise the subject of holdbacks when you describe your business has not worked with construction clients in any meaningful way.

• Reluctance to work with your accountant: Bookkeeping and accounting need to work together, especially for contractors. If a bookkeeper resists collaboration or claims your accountant is unnecessary, that is a problem.

• No cloud-based workflow: If a bookkeeper is not working in cloud-based systems, you lose the ability to access your own records, collaborate in real time, and share data with your accountant or bank without delays.

Questions to Ask Before You Hire

Before committing to any bookkeeper, ask these questions directly and pay attention to how specific the answers are.

• How do you handle job costing for construction clients? Can you walk me through your setup process?

• Have you managed construction holdbacks before, and how do you record them in the books?

• What do you do when a subcontractor payment triggers a T4A requirement?

• How do you stay current with CRA remittance deadlines, and what is your process when one is coming up?

• How will I be able to access my records, and how often will you be updating them?

• Do you work with a client's accountant directly, and what does that communication look like?

• What happens if I have catch-up work or backlogged records from prior months or years?

The answers to these questions will separate bookkeepers who genuinely understand contractor finances from those who are learning on your file.
