If your business is running on Sage, SAP Business One or another legacy ERP, you've probably already felt the limits, workarounds your team has learned to live with, reporting that needs spreadsheets to fix, rising support costs, and a system that wasn't built for the cloud. Migrating to Business Central replaces all of that with a modern Microsoft ERP, but the migration itself is what most businesses worry about. Done properly, it doesn't have to be disruptive.
Advantage Business Systems is a certified Microsoft Solutions Partner specialising in ERP migration to Dynamics 365 Business Central for UK SMEs. We've moved businesses from Sage, SAP and other legacy systems to BC, migrating data, rebuilding workflows and training teams with minimal disruption, with BC licensing from £6 per user per month. Book a free migration review and we'll map your current system to Business Central and show you the path forward.
Your master data, opening balances and transaction history are migrated from Sage, SAP or any legacy ERP into BC, fully reconciled, so nothing is lost in the move.
We plan your migration around your business calendar, phased cutover, parallel running where needed, so your team keeps working while the move happens.
Business Central replaces ageing on-premise ERP with a modern cloud system, accessible anywhere, always up to date, with no servers to maintain or upgrade.
BC licensing starts from £6 per user per month, and as a Microsoft partner we'll right-size your licences, often costing less than your current ERP's annual fees.
We rebuild your workflows in BC rather than copying old workarounds, so you land on a system that fits how your business works today, not ten years ago.
Your team is trained on BC before cutover and supported after it, and we stay on as your long-term partner, so the system keeps improving after the migration.
We start with a free migration assessment, reviewing your current ERP, data, customisations and integrations, and mapping how each translates to Business Central.
You receive a fixed migration plan covering data migration, configuration, testing, training and cutover date, with costs and timeline agreed before work begins.
We configure BC around your finance, purchasing, stock and reporting processes, improving on your old system's limitations rather than recreating them.
We extract, cleanse and migrate your data from Sage, SAP or any legacy system. then reconcile it against your old ERP so you can verify everything balances.
Your team tests BC with real data and real processes before cutover, and we train them on the system they'll actually use so go-live day holds no surprises.
After cutover we provide hands-on support while your team settles in, then remain your BC partner, managing updates and developing the system as you grow.
Moving off an ERP your business has relied on for years is a significant decision. You need a partner with verified Microsoft credentials, real migration experience across different source systems, and a track record of getting businesses live without losing data or momentum.
Advantage Business Systems is a Microsoft Solutions Partner, accredited across Business Applications, and Cyber Essentials certified, so your data is handled securely at every stage of the migration. Our team has migrated UK businesses to Business Central from Sage, SAP and other legacy platforms across manufacturing, distribution, professional services and not-for-profit, and we continue to support those customers today, because migration is where the partnership begins, not where it ends.
