FIG 01 · ERP Development
Custom ERP development and ERP integration for growing businesses
Custom ERP modules where off-the-shelf software doesn’t fit, and integrations that connect NetSuite, Business Central, SAP Business One or Odoo to your store, CRM, payments and accounting, so every order is entered once.
See how it works
FIG 02 · Quick answer
What does an ERP development company do?
An ERP development company builds or extends the system that runs your stock, orders, finance and operations. Elgrith builds custom ERP modules where off-the-shelf software doesn’t fit, and integrates ERPs like NetSuite, Business Central or Odoo with your store, CRM, payments and accounting, so data flows once without manual re-entry.

FIG 03 · Why it matters
ERP projects go over budget. Plan for where.

ERP projects over budget
Panorama’s 2026 ERP Report found that “more than a quarter of organizations exceeded their project budgets”. A written scope and a phased plan are how we keep yours honest.

55.3%
Deployed business intelligence
In the same report, business intelligence was the most deployed digital initiative, at 55.3% of organizations. ERP data pays off once people can see it, so dashboards are part of our scope.

$80
Per user per month, before any build work
Microsoft lists Business Central Essentials at $80.00 and Premium at $110.00 per user per month, paid yearly. License fees are one line of the cost; integration, data migration and training are the rest.

FIG 04 · Decide
Custom ERP vs off-the-shelf vs integration
Most growing businesses don’t need a whole custom ERP. They need the right ERP, connected properly, plus a custom module or two where their process is genuinely different.
| Buy an ERP as is | Buy and integrate | Build custom modules | Use an iPaaS | |
|---|---|---|---|---|
| What it means | NetSuite, Business Central, SAP Business One or Odoo, configured only | An off-the-shelf ERP connected to your store, CRM, payments and books | Your own modules for the processes no package handles well | A middleware platform such as Celigo, Boomi or MuleSoft runs the syncs |
| Best for | Standard processes and a small app stack | Most growing SMBs | Unusual inventory, production or field operations | Many standard connectors and an in-house admin |
| Watch for | Manual re-entry between systems | Sync design and error handling | You maintain what you build | Subscription cost and connector limits |
| Who maintains it | The vendor and your admin | Vendor, plus whoever owns the integrations | Your team or ours | The iPaaS vendor and your admin |
We often combine them: an off-the-shelf ERP, a few custom integrations, and a custom module only where it earns its keep.

FIG 08 · Integration
The parts of ERP integration that fail in production
Connecting two APIs is the easy part. These are what we design for in every ERP integration, before the first sync runs.
06principles
Sync direction and source of truth
For every record and field: which system owns it, which way it flows and what happens on a conflict.
Idempotency and retries
Webhooks and jobs that can run twice without creating two orders, and retry safely when an API is down.
Error queues and alerts
Failed records go to a queue your team can see and replay, with an alert, instead of vanishing.
Reconciliation reports
Daily checks that orders, payments and stock match across systems, so gaps show up the same day.
Rate limits and batching
Syncs designed around each ERP’s API limits, with batching for large catalogs and backfills.
Audit trail
A log of every record synced, when and by which job, for finance and for debugging.
FIG 09 · Connected
What your ERP connects to
ERP work rarely stops at the ERP. These are the services we most often build alongside it.
06principles
Payment gateways
Stripe, PayPal, Square or Razorpay payments and payouts posted to the right orders.
Payment gateway integrationOnline stores
Stores that read live stock and prices from the ERP and write orders back.
Ecommerce developmentCRM
Custom CRMs, or Salesforce and HubSpot, sharing customers and orders with the ERP.
CRM developmentCustomer and supplier portals
Portals where customers reorder and suppliers confirm, backed by ERP data.

FIG 15 · Cost
What drives ERP project cost
We don’t publish prices. These are the things that move the cost of any ERP project, ours or anyone else’s.
| Cost driver | Why it moves the price | How to keep it down |
|---|---|---|
| Number of integrations | Each system adds mapping, testing and error handling | Start with the flows that cost you the most manual work |
| Customization vs configuration | Custom code has to be built and maintained | Configure first, customize only where the process is truly different |
| Data migration | Messy data takes longest to clean and reconcile | Archive what you don’t need before you move |
| Users and licenses | ERP vendors charge per user, paid to them | License the roles you need; give others portals or dashboards |
| Process change and training | New systems change how people work | Map processes early and train key users first |
| Testing and hypercare | Month-end and edge cases surface late | Test with real scenarios before go-live |
Panorama’s 2026 ERP Report found that more than a quarter of organizations exceeded their ERP project budgets. After discovery you get a written scope and a fixed quote from us; ERP licenses are paid to the vendor.

ERP implementation vs ERP integration vs custom ERP development
Three terms that get used interchangeably, and shouldn’t be.
| ERP implementation | ERP integration | Custom ERP development | |
|---|---|---|---|
| What it is | Setting up an off-the-shelf ERP for your business | Connecting your ERP to other systems | Building ERP modules or a whole ERP as software |
| Main work | Configuration, data migration and training | APIs, syncs, error handling and reconciliation | Design, engineering and testing |
| Typical result | The ERP runs your core processes | Data flows between systems without re-entry | Software that fits a process no package handles |
| What we do | Data migration and the integrations around it | Our core ERP service | Modules where off-the-shelf doesn’t fit |
FIG 17 · Compare
Custom integration, iPaaS or point-to-point scripts?
| Custom integration service | iPaaS (Celigo, Boomi, MuleSoft) | Point-to-point scripts | |
|---|---|---|---|
| Fits | Custom logic, unusual flows, full control | Standard flows with ready-made connectors | One simple sync |
| Running cost | Hosting, which you own | A platform subscription | Low, until it breaks |
| Error handling | Designed for your process | Built in, within the platform’s limits | Often missing |
| Who can change it | Developers, with docs and code you own | Admins trained on the platform | Whoever wrote it |
| Best for | Order-to-cash with custom rules | Many standard connectors and an in-house admin | Prototypes and one-off imports |
