“We were quoted $1.2M for SAP. Maple54 built our custom ERP for $180K. Deployed in 5 months with 30% operational efficiency gain. Own it forever.”
ERPs built around your operations, not the other way around.
Generic ERPs (SAP, NetSuite, Oracle) force your operations into their boxes. Custom ERP flips that — software models your actual workflow. For complex operations, the ROI is measured in millions saved.
Operations discovery
Weeks 1-6Interview operators in every department, map workflows end-to-end, identify waste + friction, inventory integrations + data sources, compliance scoping.
Data model + modules
Weeks 7-8Master data model (customers / products / inventory / orders / finance), module boundaries, integration architecture, security + permission model.
Modular build
Weeks 9-28Inventory + purchasing + sales orders + manufacturing + finance + HR modules, built + deployed incrementally. Each module in production as soon as it's validated.
Rollout + optimization
Week 29+Phased module adoption, operator training per department, data migration, continuous-improvement sprints, quarterly operational reviews.
A complete operational backbone.
Inventory, purchasing, sales, manufacturing, finance, HR — all integrated.
Core ERP modules
Inventory + warehousing, purchasing + receiving, sales + order management, manufacturing + production, accounting + finance, HR + payroll — all custom.
Reporting + BI
Operational dashboards, financial statements, manufacturing throughput reports, inventory-aging analytics, forecasting models. Integrated with Looker / Hex / Power BI.
Integration + APIs
EDI with suppliers + customers, QuickBooks / Xero / NetSuite accounting sync, Shopify / BigCommerce for ecommerce, tax engines (Avalara / TaxJar), payroll platforms.
Mobile + field tools
Warehouse-floor apps with barcode scanning, field-service mobile apps, delivery driver apps, shop-floor production tracking, all integrated into core ERP.
Built for mid-enterprise operations at scale.
Custom ERP only makes sense for $50M+ revenue operations where off-the-shelf ERP costs exceed custom build costs, or where your operational model is a differentiator.
Manufacturing
Complex production workflows, BOM management, multi-stage assemblies, quality control, supplier chain integration. NetSuite + SAP often don't fit.
Logistics + Distribution
3PLs, warehousing companies, last-mile delivery. Real-time inventory across multiple DCs, driver dispatch, customer portals.
Healthcare Networks
Multi-facility clinics, DMEs, medical distributors. Inventory of medical products, compliance tracking, patient + provider workflows integrated.
Multi-Channel Retail
Brands with retail + wholesale + ecommerce + B2B channels. Unified inventory + pricing + fulfillment across all channels requires custom orchestration.
Boring technology. Exciting outcomes.
Deliberately narrow, battle-tested stack — same tooling that powers Shopify, Notion, Linear, and Vercel.

Custom ERP, answered honestly.
Why not just use NetSuite or SAP?
For most mid-market companies: use them. Custom ERP pays off when NetSuite + SAP cost exceeds $500K/year in licenses + consultants, OR when your operations are genuinely unique. We've seen both paths succeed; we recommend based on your situation.
How long does custom ERP take?
MVP ($300-600K): 6-9 months, 2-3 core modules. Full ERP ($600K-$2M): 12-24 months, all modules. Enterprise ($2M+): 24-36 months, multi-site deployment, complex integrations.
What about data migration?
Always the hardest part. We do 4-8 weeks of data-mapping + cleansing before go-live. Historical data preserved, incremental sync during transition, rollback plans documented.
How do you handle accounting compliance?
GAAP + IFRS support, audit trails, tax calculation (Avalara / TaxJar), financial statement generation, sync to QuickBooks / Xero / NetSuite if accounting stays external. Compliance baked in, not bolted on.
Can we adopt incrementally?
Yes — standard approach. One module in production before next starts. Typical rollout: inventory → purchasing → sales → manufacturing → finance over 12-18 months. Avoids big-bang failures.
