Xero balances your books. It cannot tell you whether that Preston aerospace job actually made money once you costed the material and the machine time.
Custom accounting software suits a Preston manufacturer that needs real job and contract costing tied to the shop floor, on top of the compliance that QuickBooks and Xero already handle well. Expect £30,000 to £80,000 and 10 to 18 weeks, and the smart move is usually to keep your ledger and VAT tool and build the costing and integration layer around it.
QuickBooks, Xero and FreshBooks are genuinely good at what they do: ledgers, invoicing, and Making Tax Digital VAT submissions to HMRC. They are not built to tell a Preston engineering firm whether a specific aerospace job made money once you account for material at the right heat-number cost, actual machine hours, sub-contract processes and rework. Job costing in a generic tool is a category tag and a hopeful guess, not a live picture built from what the shop floor actually recorded.
So finance and production run on different numbers. The accounts say the month was fine, but nobody can say which contracts carried the profit and which quietly lost money, because the labour and material data never flowed from the floor into the costing. You price the next job on the same blind spot.
What breaks first in Preston
- Job and contract costing is a rough category in Xero, not a live figure built from real labour and material
- Finance and production work from different numbers because shop-floor data never reaches the accounts
- You cannot say which contracts made money and which lost it, so pricing repeats past mistakes
- MTD VAT is handled, but everything beyond compliance is manual reconciliation between systems
The fix: accounting built for Preston, not rented
The right approach keeps QuickBooks or Xero for the ledger and MTD VAT, and builds a custom costing and integration layer that pulls real labour and material from the floor into accurate job and contract costing. It connects to your ERP (Enterprise Resource Planning) and inventory so material is costed at the right value, feeds your dashboards with contract profitability, and gives finance and production one set of numbers. You get manufacturing-grade costing without throwing away the compliance tools that already work.

The capability list that earns its budget
What we build under accounting in Preston
The engagements Preston teams bring us most often: bookkeeping software, financial reporting, accounts payable automation, accounts receivable, general ledger and expense management.
Exactly what you get
A costing and integration layer that turns your shop floor's real labour and material into accurate job and contract costing, while your existing QuickBooks or Xero keeps the ledger and MTD VAT. You get material costed at the right value from inventory, contract profitability finance and production both trust, and work-in-progress visibility across live jobs. It is manufacturing-grade costing without discarding the compliance tools that already work.
How to choose a developer in Preston
Choose a developer who tells you to keep your ledger and build costing around it, because that is the sensible path and a sign they are optimising for value. Confirm they can integrate with Xero or QuickBooks and your inventory, that costing draws on real floor data, and that MTD VAT stays intact. A team that understands Lancashire manufacturing costing will build numbers your production and finance sides can finally agree on.
- !They want to rebuild your whole ledger: ask why you should not keep Xero for MTD VAT
- !They cannot explain job costing: ask how labour and material become a real contract cost
- !They ignore inventory: ask how material is costed at the correct heat-number value
- !They skip data quality: ask what shop-floor capture the costing depends on
- !They have no manufacturing reference: ask for a build that produced real contract profitability

Frequently asked questions
What does custom accounting software cost in Preston?
A custom costing and integration layer for a Preston manufacturer typically costs £30,000 to £80,000, with a costing layer over your existing accounting at the lower end and a full contract-profitability suite at the top. You usually keep Xero or QuickBooks for the ledger, so this is costing, not a ledger replacement. Cost is driven mainly by how deep the job-costing logic goes.
Should we replace Xero or QuickBooks entirely?
Usually no. Xero and QuickBooks handle the ledger and MTD VAT well and cheaply, so the value is in building the job and contract costing they lack and integrating it. Replacing a proven compliance tool adds risk for little gain. A good developer will steer you toward keeping it and building around it.
Can it do proper job and contract costing?
Yes. A custom costing layer pulls real labour and material from the shop floor and inventory to produce accurate job and contract costs, including sub-contract and rework. That replaces the category-tag guess in generic accounting tools. For Preston aerospace work it finally shows which contracts actually made money.
Does it handle Making Tax Digital for VAT?
Your existing Xero or QuickBooks continues to handle MTD VAT submissions to HMRC, and the custom layer integrates with it rather than replacing that function. So you keep proven, compliant VAT filing while gaining costing. This is exactly why keeping the ledger tool makes sense.
How does material get costed correctly?
By integrating with your inventory system, the costing layer values material at the right cost, including the specific heat or batch cost, rather than a rough average. That makes contract costing genuinely accurate for a Preston engineering firm. Accurate material cost is often the biggest missing piece in generic accounting.
Will finance and production finally use the same numbers?
Yes, that is a core aim. Because costing is built from the same shop-floor and inventory data the production side uses, finance and production share one set of figures. That ends the common argument over whose numbers are right. It also makes pricing decisions defensible.
Do we own the costing software?
Yes. You own the custom costing and integration code, hosted where you choose, while continuing your accounting subscription for the ledger. That gives you control over the costing logic that is specific to your business. Ownership protects the part that is genuinely yours.
How long does it take to build?
Expect 10 to 18 weeks, with a costing layer over your existing accounting usually first at around weeks 10 to 13. ERP and inventory integration and fuller profitability reporting follow. The pace depends on how reliable your shop-floor data capture already is.
Is job costing worth it for a smaller Preston firm?
It is worth it when you take on varied jobs or contracts and cannot currently tell which are profitable, which quietly damages pricing. If your work is uniform or you do not need job-level costing, standard accounting is enough. Many Lancashire engineering firms need it once contract mix and material cost variation grow.

Who can build custom accounting software for a business in Preston?
Digital Heroes builds custom accounting software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, so an operator in Preston gets an assigned senior team rather than a local account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other accounting software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
