Approach Comparison
Not all bookkeeping is built the same.
General accounting and construction accounting both keep the numbers in order. What they tell you — and when — is a different matter. Here is a straightforward look at where those differences show up.
Back to HomeWhy This Matters
The right tool for the right trade
General-purpose bookkeeping works well for businesses where one month looks much like the next. Construction does not work that way. Your revenue arrives in stages, your costs sit against specific jobs, your subcontractors have deduction obligations, and retentions can sit outstanding for months after the physical work is done.
This page walks through how the two approaches handle those realities — not to criticise what general bookkeeping does well, but to be honest about where the gaps tend to appear for builders and contractors.
Side by Side
Two approaches, different results
The differences are most visible when you have three jobs running at once and need to know which one to watch.
| What you need to know | General Bookkeeping | Accountmont — Job-Based |
|---|---|---|
| Cost visibility per project | Pooled monthly | Job by job |
| Budget vs actual tracking | Rare without custom setup | Built in from day one |
| Retention management | Manual, often missed | Tracked per contract |
| Subcontractor deductions | Depends on the bookkeeper | Handled as standard |
| Profitability per contract | Only visible at year end | During and after the job |
| Stage payment reconciliation | Not typically included | Part of every report |
| Usefulness for pricing future bids | Limited without job breakdown | Direct data for each trade |
Our Approach
What shapes how we work
The distinctive elements of our approach are not the result of a methodology chosen off a shelf. They reflect years of working specifically in construction finance, where certain gaps kept appearing regardless of what software was in use.
Structured around contracts, not calendars
Every cost entry sits against the job it belongs to. The monthly summary is still there, but it is built from job-level data — not the other way around.
Retentions treated as live figures
We track what is held and when it is due rather than logging it once and moving on. That distinction matters for cash flow planning on longer contracts.
Subcontractor knowledge built in
Verification, deductions, and payment records are handled as a standard part of the service — not an add-on you have to configure yourself.
Reports that serve the next tender
Completed-contract data is presented in a way that helps you price future work more accurately — not just filed away for year-end compliance.
In Practice
Where the difference shows up
These are the practical situations where job-based accounting tends to give a clearer picture than a general monthly close would.
Situation 01
A job is running over budget
With general bookkeeping, this often surfaces at month end — or later, once the final account is raised. With job-based tracking, the variance is visible as costs are posted, while there is still room to manage it.
Situation 02
Retention is due from a client
Retention figures held in a general ledger are often checked only when someone raises the question. When retention is tracked per contract with release dates noted, the cash arrives without requiring a manual chase.
Situation 03
Pricing the next bid
A general P&L tells you overall margin. A job-level report tells you margin per trade type, per project size, per client. That granularity is what helps you know where you are thin on price and where you have room.
Investment & Value
An honest look at cost and return
Specialist construction bookkeeping costs more than a basic monthly reconciliation. That is a fair point. The question worth asking is what a missed margin problem, an uncollected retention, or a mispriced tender actually costs.
General bookkeeping
- Lower monthly fee for basic reconciliation
- Covers compliance obligations adequately
- Suitable for businesses with simple, uniform revenue
- Limited visibility on per-project performance
- Subcontractor complexity often requires additional work
- Retention figures may be missed or delayed
Accountmont — job-based
- Transparent per-job pricing from $60/active job/month
- Subcontractor deductions handled as standard
- Retention tracked and flagged before it is due
- Real-time cost visibility while work is in progress
- Completed-contract reports useful for future pricing
- Scales with your number of active jobs
Working Together
What the experience looks like day to day
Comparing approaches is useful, but the practical question is how the relationship feels when work is underway.
Standard bookkeeping relationship
- You send receipts and bank statements. A reconciled set of accounts comes back at month end.
- Queries about specific jobs require separate requests and manual compilation.
- Subcontractor paperwork is often outside scope and handled separately.
- Year-end accounts are the primary deliverable rather than in-year reporting.
Working with Accountmont
- Costs are posted against jobs as they arrive. You can see the position on any live contract without asking.
- Subcontractor verification and payment records are handled alongside the bookkeeping, not separately.
- Retention and stage payments are included in every report, not treated as a footnote.
- Completed-contract reports are produced at handover and kept accessible for future reference.
Long-Term Results
How the results look over time
The gap between general bookkeeping and job-based accounting widens the longer you work within it. In the first month the differences are procedural. Over a year, you accumulate a library of completed-contract data. Over three years, you have enough history to see which types of job, client, and contract length have consistently worked well for you — and which have not.
That accumulated insight is what informs sustainable pricing and sensible growth decisions. It does not appear automatically; it is the product of consistent, well-structured record-keeping from the start.
After one year
You have a full cycle of job-level data to compare against your original quotes. Patterns in where costs overrun start to become visible.
After three years
Enough contract history to identify your most reliably profitable work types and clients — information that directly supports smarter tendering.
After five years
A structured financial history that supports business decisions, conversations with lenders or investors, and an accurate picture of where growth has come from.
Clearing Things Up
Common misunderstandings about the choice
A few things that come up regularly in initial conversations.
"My accountant already handles everything at year end — isn't that enough?"
"Our jobs are all different — can job costing even work for us?"
"Won't this require a lot of extra work from our side?"
"Is this just for large contractors with dozens of live jobs?"
In Summary
Why the job-based approach fits construction
Clarity on each project
Know how each contract is performing independently, not as part of an averaged monthly figure.
Timely information
Cost variances visible during the job, not only after the final invoice.
Compliance handled
Subcontractor deductions and verification managed correctly alongside the bookkeeping.
Better future bids
Completed-contract data that directly informs how you price the next tender.
Retention tracked
Release dates noted per contract so cash due to you does not slip through unnoticed.
Built on sector experience
Construction finance background means common situations are understood, not explained from scratch each time.
Next Step
See whether this approach fits your work
A short conversation about how your jobs are currently tracked is enough to tell whether job-based bookkeeping would give you a noticeably clearer picture. No commitment involved.
