Job Costing & Project Bookkeeping - Know What Each Project Earns

What This Delivers

A clear picture of every job — not just the month

When your books are organised by contract, you can pull up any active job and see costs to date, budget remaining, and how things are trending. That is a very different conversation to have with yourself — or a client — than staring at a monthly P&L that mixes everything together.

The practical benefit is straightforward: you know where the numbers sit before you are committed to a final account. Decisions about labour, materials, and subcontractors happen with real figures behind them.

Beyond the immediate project, this kind of record-keeping gives you something to look back on when pricing the next bid. Actual cost codes from completed jobs are far more reliable than estimates alone.

Per job

Costs tracked against the contract they belong to — not pooled into a single overhead figure.

Live view

See variance against budget while there is still time to adjust, not after the final account settles.

Bid data

Completed job records become reference points for pricing future tenders more accurately.

Clean records

Year-end, tax, or a bank review — organised books by job make every external request straightforward.

The Situation Many Contractors Are In

The monthly report tells you very little about any single job

You carry several active contracts at once

When costs from different jobs flow into the same account and the same monthly report, it becomes genuinely hard to isolate which contract is running over budget and which has room to spare. Everything looks fine until one job quietly erodes the whole month's margin.

End-of-job surprises are more common than they should be

The final account closes and the margin is lower than expected. Without mid-project visibility into cost versus budget, this situation tends to repeat. A job that looked healthy at 60% completion can look very different at practical completion.

Pricing new work is largely based on feel

Without accurate cost records from past contracts, the next bid rests heavily on instinct and general experience. That works up to a point — but over time, job-level data tends to surface patterns that instinct alone can miss.

How This Works

Bookkeeping that follows the contract, not the calendar

Rather than posting every cost to a general overhead, we set your books up around the contracts you carry. Materials bought for a specific job go against that job. Labour allocated to a site goes to that site's cost file. The result is a running picture of each contract's performance.

We work with the way your jobs actually flow — your cost codes, your stages, your naming conventions. The setup phase is about understanding how you win and run work before we touch anything in the ledger.

Each period, costs are posted, reconciled, and checked against budget. You receive a summary for each active job without having to ask for one. If something looks off, we flag it rather than wait for you to notice.

Cost codes mapped to your jobs

We structure the chart of accounts around how you actually categorise costs on site — materials, plant, labour, subcontractors — per contract.

Budget vs. actual, per period

Each period closes with a clear variance report for every active job — what was spent, what remains, and how that compares to the original quote.

Proactive, not reactive

If costs are tracking ahead of forecast on a job, we bring it to your attention — you should not have to discover issues by digging through figures yourself.

Completed job archive

Closed contracts stay on file. When you are pricing a similar job twelve months later, the actual figures are there to look at.

Working Together

What the process looks like from your side

We take care of the bookkeeping so you do not need to. Here is how most clients find the working arrangement settles in.

Week 1–2

Initial setup

We talk through your active jobs, your cost categories, and how invoices and receipts currently reach you. No lengthy intake process — just a practical working conversation.

Week 2–3

Accounts structured

Your bookkeeping software is reorganised around active contracts. We map cost codes, set up job files, and establish the workflow for how costs get posted each period.

Ongoing

Regular bookkeeping

Each period, costs are posted against the right job. Reports come through automatically — active job summaries, variance notes, and anything that warrants a look.

As needed

Review and questions

If a figure needs context or a job is at a decision point, we are available to walk through it. You are not left with numbers to interpret on your own.

Pricing

Straightforward pricing per active job

You pay for the jobs that are active — nothing more. When a contract closes, that file closes with it.

Job Costing & Project Bookkeeping

$60 / active job / month

What is included for each active job:

Job file setup and cost code mapping to your project structure
Monthly cost posting against budget with reconciliation
Budget vs. actual variance report each period
Proactive flag if costs track materially ahead of forecast
Final job close-out summary retained on file for future reference
Support for year-end or external accountant queries related to job records

Pricing scales with the number of active jobs you carry. If your workload changes month to month, charges adjust accordingly — you pay for what is active.

How Results Are Measured

What progress looks like over time

The first thing most clients notice is simply that the picture becomes clearer. Looking at a job and knowing the current cost versus quoted cost is a different state of affairs to wondering how it is going based on the last invoice you remember receiving.

Over a few months, patterns tend to emerge. Certain cost categories consistently run over on particular job types. Knowing that is useful — it informs both how you price the next similar job and where you focus your site management attention.

The timeline for seeing a practical difference depends on how many active jobs you carry and how complex they are. Most clients find the reporting rhythm settles within the first full month, and the accumulated data becomes genuinely useful for bid pricing within two or three completed contracts.

Month 1 Accounts restructured

Job files are live, cost codes are mapped, and the first period's posting is complete. You have a baseline view of each active contract.

Month 2–3 Variance becomes visible

With two or three periods posted, you can see how costs are trending against budget on each job — and have real data to act on rather than estimate from.

First close-out Bid data established

Once a job closes, the final cost file becomes a reference point. The next similar contract has actual figures to draw on, not just memory and rough margins.

Our Commitment

You should feel confident before committing

We start with a conversation — no paperwork, no obligation, no pitch. The purpose is to understand how your jobs run and whether the way we work is a reasonable fit for your business. If it is not, we will say so plainly.

No-obligation initial call

We talk through your situation with no expectation of a commitment at the end of the call.

Transparent setup

You will understand what we are doing with your accounts and why before we begin. Nothing happens quietly in the background.

Accessible support

Questions about a figure or a job do not go into a support queue — you can reach the person looking after your books.

Getting Started

A straightforward path from here

There are four steps between a first message and having job-level bookkeeping running for your contracts.

1

Send a message

Use the contact form and give a brief note about how many jobs you typically run and what your current bookkeeping looks like.

2

Initial call

We arrange a short call to understand how you run your jobs — cost categories, subcontractors, billing stages — and confirm whether the service fits.

3

Setup phase

We structure your job files, agree on cost codes, and establish the workflow for how invoices and receipts move through the bookkeeping process.

4

Regular reporting

From the first full period, reports arrive on schedule. You will see each active job's cost position without needing to log in or ask.

Ready When You Are

Find out what your active jobs are actually costing — job by job.

A short conversation is all it takes. We will listen to how you work, and give you an honest view of whether job-level bookkeeping makes sense for your situation.
