ERP Software · London (Dagenham)
ERP Software Company in London
ERP for London and South East businesses that have outgrown spreadsheets and an accounting package: sales, stock, jobs, purchasing and finance in one system, integrated with Xero, Sage or QuickBooks and built for Making Tax Digital.
A London business usually knows it needs an ERP when month end takes a week, the stock count disagrees with the system, a customer is quoted from last year's price list, and the owner cannot get a margin by product or job without three spreadsheets and an argument. The accounting package has done its job; what is missing is the operational system around it.
Infynix Solutions implements and builds ERP systems for London and South East businesses from our office in Dagenham. Where Odoo fits, and it fits many distributors, manufacturers, construction firms and services companies, we implement and customise it with UK localisation done properly. Where the business runs on processes no package supports, we build the missing modules or build custom, and we tell you which after discovery.
Either way the UK requirements are designed in: the accounting package stays the ledger for Making Tax Digital, VAT posts correctly with digital links preserved, CIS deductions are handled for construction, payroll data flows to an RTI-compliant system, retailer EDI works for suppliers to the supermarkets and chains, and Royal Mail, DPD, Evri and the marketplaces are connected for anyone shipping product.
Distributors and wholesalers, manufacturers, construction and trades businesses, professional services firms, e-commerce and D2C brands, facilities and property companies, and any business whose current system is a set of spreadsheets one person understands.

The accounting package stays the ledger
Most London businesses run their finances in Xero, Sage or QuickBooks, and most operational systems we replace were keeping a private copy of customers, invoices and payments alongside. The two drift within a quarter, month end becomes a reconciliation exercise, and since Making Tax Digital made the accounting package the system of record for VAT, the drift is a compliance risk as well as a nuisance.
Everything we implement treats the accounting package as the ledger. Invoices, credit notes, payments and bills post through its API with the right tax codes and tracking, Stripe, GoCardless and bank feeds reconcile against it, and the ERP holds the operational detail the ledger does not need. The finance team sees one set of numbers.
Ledger is the ledger
Xero, Sage or QuickBooks remains the system of record.
Posted correctly
Tax codes, nominals and tracking mapped, not guessed.
Payments reconciled
Stripe, GoCardless and bank feeds matched automatically.
MTD compliant
Digital links preserved, submitted through compatible software.
CIS, retentions and job margin for construction
London's contractors, fit-out firms, MEP specialists and trades businesses quote on estimates and find out months later whether the job made money. CIS deductions must be applied to every subcontractor payment and reported monthly, applications for payment and retentions must be tracked, and labour, materials, subcontractors and plant need to land on the job as they happen.
We build job costing that captures each cost at source, from mobile timesheets, supplier invoices and stock issues, handles CIS status and deductions at payment, manages applications and retentions, and reports margin by job, phase and customer while there is still time to act.
CIS built in
Verification status, deductions and monthly return data.
Applications and retentions
Construction billing handled properly.
Costs at source
Timesheets, purchases, subcontractors and plant on the job.
Margin by job
Estimate versus actual, live.
Supplying the supermarkets and shipping the orders
Distributors supplying UK retailers are expected to receive orders and send advices and invoices over EDI in each retailer's format, with the right barcodes and delivery windows; chargebacks for mistakes come off the margin. E-commerce brands need every order to reach the warehouse, the carrier and the accounts without a person in between.
We integrate retailer EDI into the order and despatch flow, connect Royal Mail, DPD, Evri and DHL for labels and tracking, sync Amazon and eBay stock and orders, and post everything to the accounts with the correct VAT treatment.
Retailer EDI
Orders in, advices and invoices out, per retailer specification.
Carrier labels
Printed from the order, tracking back to the customer.
Marketplace sync
Amazon and eBay stock and orders in one place.
Accounts correct
Every order posted with the right VAT.
Go-live without losing a week
The riskiest fortnight of an ERP project is the cutover. Customers, products, prices, stock and open orders must come across clean, the team must know the new system, and the old one must stay available. Businesses that go live on untested data spend a month recovering.
We migrate in rehearsals, train each role on their own workflows, run the pilot team on real transactions before cutover, plan go-live for the quietest point in the calendar, and stay on hypercare for the weeks after so issues are fixed the same day.
Rehearsed migration
Data loaded and checked more than once.
Role-based training
Each team on its own screens and tasks.
Pilot before cutover
Real transactions by real users first.
Hypercare
Same-day fixes in the weeks after launch.

Frequently Asked Questions
Should we buy an off-the-shelf ERP or build one?
It depends on how unusual the processes are. Where Odoo or another platform fits, we implement and extend it; where the business runs on workflows no package supports, custom is cheaper over five years. Discovery tells you which, and the specification is yours either way.
How much does ERP cost in London?
We do not quote from a rate card. Discovery establishes the modules, users, integrations and data involved, and the proposal is a fixed price for that scope with support quoted separately. A modular rollout can spread the investment.
Does it work with Xero, Sage or QuickBooks?
Yes. The accounting package stays the ledger. Invoices, bills, payments and credits post through its API with the right tax codes, and reconciliation runs against bank feeds and payment providers.
Is it compatible with Making Tax Digital?
Yes. Digital records and digital links are preserved, VAT is posted correctly on every line, and submissions go through compatible software from data that was right at source.
Can it handle CIS for our subcontractors?
Yes. Subcontractor verification status, deductions at payment, statements and monthly return data are built into the job and purchase workflows.
Can you connect us to retailer EDI and UK carriers?
Yes. Orders, advices and invoices exchanged with UK retailers in their formats, and Royal Mail, DPD, Evri and DHL integrated for labels and tracking.
How long does an implementation take?
Ten to twenty weeks for most London businesses, in stages, with the pilot team using the system well before cutover.
Can you rescue a failed implementation?
Yes. We audit the configuration and data, fix what is blocking a usable go-live, and either complete the implementation or plan a controlled replacement.
Where are you based?
Dagenham, in Greater London. Discovery, training and go-live happen on site; configuration, build and support run from our office with fortnightly demos.
