QuickBooks closes your Mobile shipyard's month, but it can not tell you the margin on hull 17 while the work is still happening
Custom accounting software for a Mobile business typically costs $50k to $120k and 4 to 7 months, though most firms are better served by a custom layer on top of QuickBooks or Xero for $35k to $70k. You build past off-the-shelf accounting when your business is project-based with job costing, progress billing, retainage, and contract requirements (Navy, aerospace) that QuickBooks and Xero handle clumsily or not at all. The general ledger they do well; the way a shipyard actually makes money is what they miss.
QuickBooks and Xero are great general ledgers for a business that invoices and gets paid. A Mobile shipyard's economics are project-based: every hull and dry-dock period is its own profit center with labor, materials, change orders, progress billing, and retainage. QuickBooks can fake job costing with classes and tags, but it cannot tell you the live margin on hull 17 while the work is in progress, so you find out whether a job made money after it is over and too late to fix.
Aerospace and Navy contract work makes it worse. Those contracts demand cost accounting and audit trails (DCAA-style) that off-the-shelf small-business accounting was never built for. So finance exports to Excel, rebuilds job costs by hand, and the books and the project reality drift apart.
Budgeting a accounting build in Mobile
| Project scope | Typical cost | Timeline |
|---|---|---|
| Job-costing layer over QuickBooks or Xero | $35k to $70k | 3 to 5 months |
| Contract-accounting platform with DCAA reporting | $75k to $130k | 5 to 8 months |
| Progress-billing and retainage module + integrations | $40k to $75k | 3 to 5 months |
The case for owning your accounting
Most Mobile firms do not need to replace QuickBooks; they need a job-costing and contract-accounting layer that off-the-shelf cannot provide. That layer gives live margin per hull or dry-dock period, real progress billing and retainage, and DCAA-ready cost accounting for Navy and aerospace work, while QuickBooks or Xero stays the general ledger. It pulls labor and material from your ERP (Enterprise Resource Planning) and project-management-software so job cost is current, not reconstructed in Excel at month-end. You keep the proven ledger and add the part that fits how you actually earn.
- Your business is project-based and QuickBooks can't show live job margin
- You need real progress billing and retainage off-the-shelf handles clumsily
- Navy or aerospace contracts demand DCAA-style cost accounting
- Finance rebuilds job costs in Excel every month from your project systems
- Your business is not project-based and a standard GL covers you
- QuickBooks or Xero with classes and tags is genuinely good enough
- You have no contract or DCAA cost-accounting requirements
- You don't have project systems to feed a job-costing layer

Delivery, week by week
Exactly what you get
The job-costing and contract-accounting layer QuickBooks never had. Live margin on hull 17 while the work is still happening, real progress billing and retainage on ship-repair contracts, and DCAA-style cost accounting ready for a Navy or aerospace audit. Labor and material flow in from your ERP and project-management-software so job cost is current, not rebuilt in Excel at month-end. QuickBooks or Xero stays the general ledger, two-way synced, so you keep the proven ledger and add exactly the part that fits how a Mobile shipyard earns.
How to choose a developer in Mobile
Be wary of anyone who wants to replace QuickBooks outright, because the general ledger is a solved problem and the real value is the job-costing layer on top. Ask for a past build with live job margin, progress billing, and retainage, and confirm they understand DCAA-style cost accounting if you do Navy or aerospace work. Insist on live feeds from your ERP and project-management-software so job cost is never reconstructed by hand, and on a clean two-way sync with QuickBooks or Xero. The right partner adds the project-accounting brain and leaves the proven ledger alone.
- Live margin per hull or dry-dock period while the work is still in progress
- Real progress billing and retainage for ship-repair and construction contracts
- DCAA-style cost accounting and audit trails for Navy and aerospace work
- Job cost pulled live from ERP and project-management-software, not rebuilt in Excel
- Keeps QuickBooks or Xero as the general ledger so you don't replace what works
- Building a full accounting system is rarely worth it; the GL is a solved problem, so most value is in the job-cost layer
- You take on audit and tax logic that off-the-shelf vendors maintain, if you go full custom
- Integration with payroll, banking, and tax filing still depends on proven external systems
- If your business is not project-based, QuickBooks or Xero alone is genuinely sufficient
- !They propose replacing QuickBooks wholesale; ask why not keep the GL and add a job-cost layer
- !No job-costing experience; ask for a past build with progress billing and retainage
- !They ignore DCAA needs; ask how Navy and aerospace cost accounting is handled
- !No live ERP feed; ask how job cost stays current instead of rebuilt monthly
- !No two-way GL sync; ask how the layer and QuickBooks stay reconciled

Frequently asked questions
How much does custom accounting software cost in Mobile?
A job-costing layer over QuickBooks or Xero runs $35k to $70k over 3 to 5 months and is what most firms actually need. A full contract-accounting platform with DCAA reporting runs $75k to $130k. A progress-billing and retainage module with integrations runs $40k to $75k.
Should we replace QuickBooks entirely?
Almost never. QuickBooks and Xero are excellent general ledgers, and rebuilding that is wasted money. What project-based Mobile firms lack is live job costing, real progress billing and retainage, and DCAA-style contract accounting, which is best added as a layer on top of the ledger you keep.
Why can't QuickBooks job-cost our shipyard work?
It can approximate job costing with classes and tags, but it cannot show live margin on a hull or dry-dock period while the work is in progress, and it handles progress billing and retainage clumsily. For project-based work where every hull is its own profit center, that gap means you learn whether a job made money only after it is too late to act.
