There's a particular kind of pain that finance leaders know too well: you've finally secured budget approval for a new AR system. You've run the RFP. You've selected a vendor. And then someone from IT drops the bomb: "Implementation? Yeah, we're looking at 12 to 18 months. Maybe longer if we need custom fields."
Welcome to the world of legacy relational databases, where every tweak requires a developer, every data model change triggers a change request, and your "transformative" AR platform becomes just another rigid product you're forced to work around.
But here's the thing: that 12-month roadmap is dying. And it's being killed by a new wave of Dynamic Data Model (DDM) platforms that are fundamentally rethinking how businesses buy, implement, and own software.
Most "enterprise-grade" AR systems, yes, including the big names like HighRadius, are built on relational databases that were designed decades ago. These systems work fine if your business never changes. But when was the last time that was true?
Here's what happens in practice:
The result? You end up with a product that dictates how you work, not a platform that adapts to how you want to work.
And the ROI you were promised? It evaporates under the weight of customisation fees, consultant hours, and the opportunity cost of moving too slowly in a fast-changing market.
Dynamic Data Models flip the script. Instead of forcing your business processes into a rigid database schema, DDM platforms let you create data models in hours that match your exact requirements, no more trying to map your invoices, customers, and payment terms into a legacy structure that was designed for someone else's business.
Here's how it works:
With a DDM platform, you're not locked into predefined tables and fields. You define what "customer," "invoice," and "payment" mean for your business. Need to track additional attributes for specific customer segments? Add them. Want to model complex payment hierarchies? Build them. All without writing a line of code or filing a ticket with IT.
Legacy relational databases compound in complexity as your data grows. Add more customers, more invoices, more transactions, and suddenly your system slows down, your costs balloon, and your IT team is scrambling to optimise queries.
DDM platforms scale linearly. More data doesn't mean exponentially higher costs or degraded performance. It means predictable, transparent scaling that doesn't blow up your budget as you grow.
The result? A 70% reduction in technology costs compared to legacy systems.
Most AR systems are built in modules: one for invoicing, one for collections, one for cash application, one for credit management. Each module has its own data silo, its own UI, its own logic. And good luck automating across them.
A DDM platform unifies order-to-cash into a single, cohesive data model. You eliminate silos. You automate end-to-end workflows: from invoice generation to cash application to day sales outstanding monitoring: without duct-taping modules together.
The result? A 300% increase in outcome-centric automation compared to relational systems.
Here's where the "12-month IT roadmap" truly dies.
With a DDM platform like Invevo, you don't start from scratch. You start with an 80% ready, sector-specific baseline on Day 1. The platform is pre-configured with industry best practices, workflows, and data models that match your sector: whether you're in recruitment, building supplies, media, or property management.
From there, the Product Team (not a third-party consultant) works with you through a rapid onboarding process to tailor the final 20% to your exact requirements. No multi-month discovery phase. No endless workshops. Just fast, focused configuration that gets you live in weeks, not quarters.
The result? A 90% reduction in implementation time compared to legacy systems.
And because the platform is designed for change, you're not locked in. As your business evolves: new markets, new products, new payment terms: you adapt the platform in hours, not months. Business users become platform experts, making changes without IT bottlenecks.
The result? A 90% reduction in the hidden cost of change.
When you're evaluating AR systems, there's one question that cuts through the noise:
"Am I buying a product: and accepting its limitations: or am I buying a platform that can be adapted to how I want to work?"
Legacy systems are products. They come with predefined workflows, rigid data models, and a high cost of ownership that compounds as your business scales. You're renting someone else's vision of how AR should work.
DDM platforms are platforms. They come with flexibility, configurability, and a low cost of change that scales linearly as you grow. You're buying the ability to define how AR works for you.
This distinction matters because the ROI isn't just about features. It's about ownership. About agility. About whether your AR system is an asset or a liability.
Let's talk outcomes. Because at the end of the day, the only thing that matters is whether your AR system improves your business: not whether it checks boxes on an RFP.
Here's what DDM platforms deliver:
These aren't hypotheticals. These are the results companies are seeing when they move from rigid, relational AR products to flexible, dynamic AR platforms.
And if you're tracking metrics like the arr accounting formula or day sales outstanding meaning, a DDM platform gives you the agility to adapt your KPIs, dashboards, and reporting in real time: without waiting for IT to build a custom report.
Before you commit to a new AR system, ask your vendor for a sandbox or proof of concept.
If they hesitate, run.
The inability to provide a low-friction POC is a tell-tale sign that:
A true DDM platform can spin up a sandbox environment in hours and give you hands-on experience with the configurability, flexibility, and performance you're being promised. If a vendor can't do that, they're selling you a product: not a platform.
Here's where it gets even more interesting.
The next wave of DDM platforms isn't just about flexible data models: it's about AI-accelerated configuration. Imagine this: AI builds your ERP integration. AI designs the data transformations. AI creates the workflows and visualisations. AI guardrails the calculations to ensure compliance and accuracy.
You go from "12 months of IT roadmap planning" to "12 hours of AI-assisted platform configuration."
We're not there yet. But the foundations are being laid right now. And companies that adopt DDM platforms today are positioning themselves to take advantage of AI-driven automation tomorrow.
The 12-month IT roadmap isn't just dying: it's already dead for companies that have embraced the DDM revolution.
The question is: are you still trying to force your business into a rigid, relational product? Or are you ready to adopt a platform that adapts to you?
If you're tired of waiting on IT, paying for change requests, and watching your AR system become a bottleneck instead of an accelerator, it's time to rethink your approach.
Explore how Invevo's DDM platform can transform your AR operations: with 90% faster onboarding, 70% lower costs, and a low cost of change that keeps pace with your business.
Because in the end, the best AR system isn't the one with the most features. It's the one that gets out of your way and lets you work the way you need to work.
