Business Central Alternative
Replacing an aging ERP with Microsoft Dynamics 365 Business Central trades a system you've outgrown for per-user licensing, partner-gated customization, and a roadmap you don't control. Slingr builds you a custom ERP shaped around how your business actually runs — one you own outright.
Before you sign
Full and team-member seats, premium tiers, and per-user add-ons mean the bill grows with headcount — not with the value the system delivers. You're renting access, every year, forever.
Real changes mean extensions, a VAR's hourly rate, and waiting on Microsoft's release cadence. The business logic that makes you you lives inside someone else's platform and pricing.
Your batch processes, your costing, your compliance — reshaped to match the ERP's assumptions. The fit is never quite right, and the gaps go back onto spreadsheets.
What we build instead
Slingr maps the workflows that actually run your business — purchasing, inventory, production, sales, financials — then builds an ERP around them. AI-accelerated, documented, and yours.
The data model and workflows match how your business runs, not a generic template. No "best practice" you have to bend into — your operation leads, the software follows.
Add users, sites, and workflows without a license meter. You own the application, so growth doesn't multiply your software bill.
Connects to the systems you keep — banking, EDI, CRM, shop floor — on a shared data layer instead of a tangle of point-to-point exports.
Built in weeks at roughly 50–60% of traditional cost, senior-engineer reviewed — production-hardened and audit-ready, not throwaway AI code.
Proof
A US manufacturer running a decades-old DOS-based ERP weighed Business Central — and chose a custom platform Slingr built and they own, module by module, with no operational downtime. Anonymized at the client's request; details available under NDA.
The glide path
Stand up the new platform alongside the legacy ERP and connect to what stays. Nothing rips out on day one.
Move module by module — purchasing, inventory, production, sales — validating data at each step against the source system.
Retire the legacy ERP once financials cut over. You keep the data and own the platform that replaced it.
Questions buyers ask
Yes. Instead of licensing Dynamics 365 Business Central per user, Slingr builds a custom ERP modeled on your actual operation, with the source code and data owned by you and no per-user licensing.
Yes, on a glide path — purchasing and inventory first, financials last — with data validated against the source system at each step, so the business keeps running throughout.
There are no per-user seats. You pay to build the platform once and own it; AI-accelerated delivery runs roughly 50-60% of traditional cost and time.
Yes — banking, EDI, CRM, and shop-floor systems connect on a shared data layer rather than brittle point-to-point exports.
Describe what you run on today and where it falls short, and get a budgetary scope back the same day — whether or not you build with us. You'll own the source code, the data, and the roadmap.
