Your Coventry plant's real margin is hidden in QuickBooks behind one big sales figure
QuickBooks, Xero, and FreshBooks keep your books compliant and tell you almost nothing about where a Coventry manufacturer actually makes or loses money, because they can't job-cost a multi-year programme or track landed cost on imported components. Custom accounting and costing software costs £40,000 to £100,000 over 3 to 6 months and pays back by showing true margin per programme, not one blended sales line.
QuickBooks and Xero are general-ledger tools. They'll produce a clean P&L and a VAT return, but a Coventry EV-component or precision-machining business needs to know the margin on a specific OEM programme, after material, labour, freight, and tariff, and the off-the-shelf package collapses all of that into one sales figure. So your most important financial question, which work is actually profitable, gets answered in a spreadsheet, if at all.
Landed cost makes it worse. When you import battery cells or electronics, the real cost of a part includes freight, duty, and currency, and that lands days or weeks after the invoice. QuickBooks treats the purchase price as the cost, so your margins look fine until a CMA-CGM freight spike or a tariff change quietly eats the contract, and the accounts only reveal it a quarter late.
Where the off-the-shelf tools fall short
- Programme-level margin is hidden behind one blended sales figure in QuickBooks
- Job costing across material, labour, freight, and tariff lives in a spreadsheet
- Landed cost on imported components isn't reflected, so margins look better than they are
- By the time the accounts show a problem contract, it's a quarter too late
Custom accounting: what Coventry teams actually get
Custom accounting and costing software job-costs every programme: it captures material, labour, freight, duty, and currency as landed cost, and shows true margin per part family and per OEM programme in something close to real time. You stop running the business on a blended P&L and start seeing which contracts pay and which quietly bleed, while you can still do something about it.
- You need margin per programme, not one blended figure
- Imported components make landed cost material to your margins
- Job costing currently happens in a spreadsheet
- Contracts can quietly turn unprofitable before the accounts show it
- A single product line makes blended margin good enough
- You don't import components with significant landed cost
- QuickBooks or Xero answers your margin questions
- You only need statutory accounting and VAT
- True margin per OEM programme and part family, not one blended sales line
- Landed cost capturing freight, duty, and currency on imported components
- Job costing that ties material, labour, and overhead to the actual work
- Early warning when a freight spike or tariff change erodes a contract
- Clean integration with your statutory accounting and VAT obligations
- More than a QuickBooks or Xero subscription, with a build timeline
- You usually keep statutory accounting in the off-the-shelf tool and integrate
- Accurate costing depends on disciplined data from the shop floor
- Overkill if a single product line makes blended margin good enough

Timeline: what happens, and when
Exactly what you get
A costing and margin layer that finally answers which work pays: job costing across material, labour, and overhead, landed cost that folds in freight, duty, and currency on imported components, and real-time margin per OEM programme and part family. Variance alerts warn you when a contract slips below threshold while you can still act, and it integrates with QuickBooks or Xero so statutory accounts and VAT stay where they belong. It draws live data from your ERP (Enterprise Resource Planning) and your inventory management system, and feeds your BI (Business Intelligence) dashboards.
How to choose a developer in Coventry
Ask how they'd job-cost a multi-year OEM programme including freight and tariff, and how they'd integrate with Xero or QuickBooks rather than replace it, because the right answer keeps statutory accounting where it works and adds costing where it's missing. A developer who understands Coventry's import-heavy EV and electronics supply chains will treat landed cost as central, knowing that a freight spike or tariff change is exactly what turns a healthy-looking contract into a loss the blended P&L hides.
- !They want to replace QuickBooks; ask why they wouldn't keep it for statutory accounts
- !No landed-cost experience; ask how freight and duty reach the part cost
- !Costing is a flat overhead; ask how labour and material tie to the job
- !No variance alerts; ask how a contract's eroding margin gets flagged early
- !No shop-floor data plan; ask where accurate job costs come from

Frequently asked questions
Should we replace QuickBooks or Xero?
Usually not. They handle statutory accounts and VAT well, so the smart approach keeps them and adds a custom costing layer for the thing they can't do, programme-level job costing and landed cost. The two integrate, with the off-the-shelf tool staying as your general ledger.
What is landed cost and why does it matter here?
Landed cost is the true cost of a part once freight, duty, and currency are included, which for imported EV cells or electronics can land weeks after the invoice. QuickBooks treats purchase price as cost, so margins look fine until a freight spike or tariff change quietly erodes the contract.
How does this show margin per programme?
By job-costing each OEM programme across material, labour, and overhead and presenting margin per programme and part family in real time, instead of collapsing everything into one sales line. That tells you which contracts pay and which bleed, while you can still act.
