QuickBooks does your Sunderland books, but it can't cost a Nissan sequence change or tie labour to the shift that caused it

Typically £25k to £80k. A costing and reporting layer over Xero or QuickBooks is £25k to £42k, while a full custom system with job costing and MTD reaches £80k. Costing logic and integrations drive the cost, and most firms need the layer, not a full rebuild.

Almost always build around them. QuickBooks and Xero handle bookkeeping, VAT and MTD filing well, so the value is a costing and integration layer that connects them to production. A full custom ledger is rarely justified, and a good partner will say so.

Yes, that's the main reason to build. It ties a job's cost to the actual materials, machine hours and shift labour it consumed, turning estimated margins into facts. Off-the-shelf tools can't do this because they were never connected to your production.

Yes, VAT filing under Making Tax Digital is built in and runs on connected, accurate data. Keeping MTD rules current is part of the ongoing arrangement, so confirm who owns that. Compliance sits alongside the costing, not against it.

By integrating your ERP, inventory and payroll so production events post automatically into the accounts. That ends the copy-paste and the month-end reconciliation of differences. The books become useful mid-week, not just at close.

Ten to sixteen weeks. A costing layer over your existing ledger can be live in ten to twelve weeks, while a full custom system takes fourteen to sixteen. Testing against real month-end data is a stage you don't rush.

Yes, on a custom build you own the system and the financial data outright, confirmed in the contract. That control matters for sensitive financial information and audit. Vague ownership terms are a reason to pause.

Yes. Because cost is captured against real production, you get live profitability by job, product and customer rather than a blended month-end figure. That's what lets you quote and price from facts.

For production-linked costing, a partner who understands manufacturing finance and can sit with your finance team will model it correctly. A North East team familiar with local industry is ideal. Once the costing rules are set, ongoing work can be remote.

Bring three things: the 5 to 10 workflows that hurt most today, sample data such as your chart of accounts and a redacted month of transactions, and a list of every system the software must connect to, including banks and payroll. You do not need a formal spec; a good agency writes that with you during discovery. In our experience buyers who arrive with concrete workflow pain get accurate quotes, and buyers who arrive with a feature wishlist get padded ones.

You should, outright, and the contract must say so with an explicit IP assignment clause rather than a usage license. Insist that the code lives in a repository you control from day one, so nothing, including the ledger schema and migration scripts, can be held back at the final invoice. Third-party libraries and any framework the agency reuses stay under their own licenses, and a clean contract lists exactly which those are.

Almost always yes, through CSV exports or the vendor's API, and migration should be scoped as its own workstream with field mapping, a dry run, and a planned cutover window rather than an afterthought. The real time sink is rarely moving the data; it is cleaning it, since years of duplicates, free-text fields, and inconsistent formats surface all at once. Pull a full export from your current vendor before committing to anything new, because some SaaS plans restrict exports on lower tiers.

Three to five for a typical focused build: a project lead, one or two engineers, a designer, and part-time QA, which is the standard shape across 2,000+ Digital Heroes projects. Larger platforms justify 6 to 10, but a ten-person team on a small first version usually signals bill padding rather than horsepower. What predicts success is whether a senior engineer is writing your code daily, not the headcount on the proposal.

The three we see most across Digital Heroes rescue projects: replacing everything at once instead of automating the most painful workflow first, skipping the parallel run so errors surface in live books, and letting developers design the ledger without an accountant reviewing the data model. A fourth is quietly expensive: no assigned owner for tax rate and compliance updates after launch. Every one of these is cheap to prevent and costly to unwind.

It encodes your actual business rules: progress billing tied to project milestones, revenue recognition for your specific contract types, landed cost tracking, or approval chains that match your org chart. Off-the-shelf tools handle generic bookkeeping well but force every business into the same chart of accounts and workflow. FreshBooks, for example, is built around freelancer-style invoicing, so inventory or multi-entity accounting means leaving the product entirely.

Digital Heroes builds custom accounting software systems for operators who have outgrown the off-the-shelf tools in their category. The work is delivered remotely: our engineers work from Delhi and Lucknow, leadership is in New York, and some team members live in London and Sydney and work remotely from there. We have no office in Sunderland. You can chat with the team directly, and every form gets an email reply within 24 hours.
