ERPNext Implementation & Support Across the UK

UK manufacturers sit between accounting software that stops at the office door and ERP priced for corporations. ERPNext closes that gap with full production depth and open-source licensing. Sigzen, a certified ERPNext and Frappe partner, implements it for UK manufacturers with Making Tax Digital VAT configured, readiness for the April 2029 e-invoicing mandate, and a team working inside your business day.

Why Sigzen

Why UK manufacturers work with Sigzen on ERPNext

Most UK SME manufacturers outgrow Sage or Xero long before they can justify a proprietary manufacturing ERP. ERPNext fills that gap, and Sigzen, a certified ERPNext and Frappe partner, implements it with UK VAT and MTD configured from the start.

Making Tax Digital handled properly

MTD requires VAT records to be kept digitally and returns filed through software rather than typed into the HMRC portal. Sigzen configures ERPNext's VAT handling and the submission route during implementation, so returns come from the same records that hold your invoices instead of a spreadsheet assembled each quarter.

Ready for the April 2029 e-invoicing mandate

Electronic invoicing becomes mandatory for VAT invoices in April 2029, with HMRC's full implementation plan due in the 2026 Budget and PINT UK on the Peppol network the expected format. ERPNext already produces structured invoice data and supports Peppol-family formats, so the UK route is a configuration step once the specification is published, not a system replacement.

No per-user licence fees

ERPNext is open source. A forty-person engineering firm pays for implementation and hosting, not for seats, and the next ten users cost nothing in software. Against quotes that scale per user per month, that difference often decides whether the project happens.

Built for job shops, not just ledgers

Works orders, routings, operation-wise costing, quality checks and quoting from real bills of materials are the core of ERPNext. Estimators quote from what similar jobs actually cost, and margin per job is visible while the job is still on the floor.

The records your customers audit

Whether you hold ISO 9001, IATF 16949 or AS9100, customers audit records. ERPNext maintains lot and serial traceability, inspection results, nonconformance records, calibration schedules and certificates of conformance linked to every despatch.

Your data where you choose

ERPNext can be self-hosted on your own servers or with a UK hosting provider, so data-residency questions have a simple answer and no vendor holds your production data behind a subscription.

How We Implement

How an ERPNext implementation runs in the UK

UK SME manufacturers rarely have anyone spare for a two-year ERP programme. Sigzen's approach puts a working system into a small team's hands quickly and deepens it from there, with every session inside your working day.

Discovery in your hours

Sigzen maps how your shop really runs: quoting and estimating, purchasing, the route a job takes through the floor, inspection points, despatch and invoicing. India is four and a half to five and a half hours ahead, so sessions run in your morning and afternoon rather than at either side's inconvenience.

Set up VAT and MTD first

Chart of accounts, VAT schemes including reverse charge and margin schemes where they apply, and the MTD submission route are configured before operational work begins, so the first quarter after go-live is not a scramble.

Configure the shop floor

Bills of materials, routings, works orders, operation-wise job costing and quality checkpoints are configured to mirror the mapped flow, with scrap and rework captured where material is actually lost.

Migrate from Sage, Xero or spreadsheets

Customers, suppliers, parts, bills of materials, open orders and balances move across after verification and de-duplication, with historical job costs where they exist, because that history is what makes future quoting accurate.

Test with your own jobs

Recent real jobs run end to end before go-live: quotation, order, purchase, production, inspection, delivery note and invoice, plus a full VAT return cycle.

Train by role, recorded

Estimators, buyers, shop supervisors, quality and accounts each learn their daily screens on your own data, and every session is recorded so the next hire trains from the same material.

Go live, then keep improving

Sigzen supports the first weeks live during your working day, including the first month-end close and the first MTD submission. After stabilisation the work turns to the reports owners run on: margin per job, on-time delivery, scrap by reason, quote-to-win rate.

Good to Know

Frequently asked questions

Does ERPNext support Making Tax Digital for VAT?

Yes, with configuration. MTD requires VAT records to be kept digitally and returns submitted through compatible software rather than typed into the HMRC portal. Sigzen configures ERPNext's VAT handling and the submission route during implementation, so your return is produced from the same records that hold your invoices.

Will ERPNext be ready for the UK e-invoicing mandate in 2029?

Electronic invoicing becomes mandatory for VAT invoices in April 2029, and HMRC's full implementation plan is due in the 2026 Budget, with PINT UK on the Peppol network the expected format. ERPNext already produces structured invoice data and supports Peppol-family formats through the European e-invoice integration, so Sigzen will configure the UK route once the technical specification is published. This is a configuration step, not a system replacement.

Can ERPNext replace Sage or Xero for a UK manufacturer?

Yes, and it is the most common starting point. ERPNext covers the accounting those systems handled and adds quoting, purchasing, works orders, stock, quality and job costing in one platform, with your existing data migrated during implementation.

What does ERPNext cost compared with UK manufacturing ERP systems?

ERPNext is open source with no per-user licence fees, so cost concentrates in implementation and hosting. For most UK SME manufacturers the first-year total lands well below proprietary quotes, and year two carries no seat renewal at all.

Where will our data be stored?

Wherever you decide. ERPNext can be self-hosted on your own servers or with a UK hosting provider you choose, which keeps data-residency questions straightforward to answer.

Does Sigzen have a UK office?

No. Sigzen operates from Ahmedabad, India and delivers UK implementations remotely, with on-site visits arranged where a project needs them. India runs four and a half to five and a half hours ahead of UK time, so the team is available across your full working day and sessions are recorded.

Can ERPNext support ISO 9001, IATF 16949 or AS9100?

ERPNext maintains what these audits examine: revision control, lot and serial traceability, inspection results, gauge calibration schedules, nonconformance and corrective actions. Sigzen configures these around your existing quality manual rather than imposing a template.
