Custom ERP development for teams that have outgrown the spreadsheet and refuse to retrofit NetSuite. We design, build, and run real production systems — the modules you actually need, nothing you don't.
Trusted by teams shipping production software
We build the system your business runs on. Custom ERP means your business logic is the code — not a workaround on top of someone else’s product. We build only the modules you need, integrate the tools you already use, and we run two production ERPs of our own (Agency ERP and Reliable Training), so we know what shipped looks like.
Off-the-shelf fits someone else.
You start with NetSuite, SAP, Odoo, or Acumatica — then spend a year and six figures bending it to your workflow, and still end up with workarounds and side spreadsheets.
The licenses never stop.
The license keeps renewing, the customizations break on every upgrade, and the consultants charge by the hour without ever understanding how you actually run.
Your tools don't talk.
Sales, ops, and accounting live in separate systems with manual handoffs — so the same data gets re-entered three times and nobody trusts the numbers.
Every custom ERP we ship covers these areas. You don't get every module on day one — we ship the ones you need first, then layer in the rest.
- 01
Discovery & data model
We map your workflow end-to-end, model the entities, and lock the data model before any UI gets built. Done right, this is half the project.
- 02
Operations modules
Projects, jobs, scheduling, dispatch, inventory, manufacturing — whatever your operations actually look like. Built from scratch, fitted to your process.
- 03
CRM & sales
Leads, contacts, deals, quotes, invoices, payments. Integrated with the rest of the ERP so handoffs from sales to ops are automatic.
- 04
Accounting & finance
GL, AP/AR, expense tracking, multi-currency, tax. We integrate with QuickBooks or Xero if you'd rather keep your accountant happy, or build native modules.
- 05
Reporting & dashboards
Real-time dashboards for the metrics your team actually watches. No more exporting CSVs into Excel every Monday.
- 06
Integrations
Stripe, QuickBooks, Shopify, HubSpot, Salesforce, custom APIs, EDI, file imports. Everything wired into the same data model.
- 07
Permissions & audit
Role-based access, field-level permissions, full audit log. Compliance-ready out of the gate — important for SOC 2, HIPAA, or financial audits.
- 08
Multi-tenant if you need it
Building an ERP for your customers, not just yourself? We've shipped multi-tenant systems with tenant isolation, per-tenant theming, and admin oversight.
- 09
Documentation & handover
Every system ships with documentation your team can read. If you ever want to take over the code, you can — it's standard Next.js, Postgres, TypeScript.
Built for how your industry actually runs.
Every industry has its own version of “generic ERP doesn’t fit.” See how we adapt the same build process to yours.

No eighteen-month projects. No big-bang launches. We ship the first module to your team in 4–8 weeks, then build the rest while they're already using it.
Discover
1–2 weeks. We sit with your team, map the workflow, and pick the first module to ship. Output: a written scope and architecture diagram.
Architect
1–2 weeks. We design the data model, the integrations, and the deployment topology. We're protective of this step — it's where bad ERPs are born.
Build slice 1
3–5 weeks. First production module — usually the highest-pain part of your current workflow. Your team starts using it the day it ships.
Build slices 2–N
1–3 months. We add modules one at a time, deploying continuously. Each module integrates with the existing data model. Nothing is built twice.
Run
Ongoing. We stay on after launch — bug fixes, new features, integrations as your business changes. Optional but most clients keep us close.
Modern, boring, and well-supported. We pick tools your future team will be able to hire for — no proprietary lock-in.

“They shipped a working ERP module in six weeks that our last vendor quoted six months for.”
Module Ship
One focused module — scheduling, CRM, ops, or a specific reporting layer. Ideal if you have an existing ERP and need a custom piece on top.
- 1 production module
- Data model + integrations
- 4–6 weeks to ship
- Documentation + handover
Agency ERP
The ERP we built for our own ops. Projects, billing, capacity, client work — it runs the agency. Direct proof we know what production ERP looks like.
Reliable Training
A full multi-module ERP for an equipment-operator training business: scheduling, registration, payments, instructor rosters, accounting, and insights.
Olliebooks
Bookkeeping and financial-ops tooling — the kind of accounting layer that plugs straight into a custom ERP build.
Clear answers
for complex builds.
Clear answers on timelines, pricing, ownership, and what shipping actually looks like with a senior engineering team.
ERP stands for Enterprise Resource Planning — software that unifies core business processes (finance, inventory, projects, HR, CRM) into one connected system instead of a dozen disconnected tools. “Custom ERP” means that system is built around your specific workflow instead of a rigid off-the-shelf template.
Classic examples are NetSuite, SAP, and Microsoft Dynamics — large, generalized platforms companies configure to fit their business. A custom ERP example looks different: our own Agency ERP runs projects, billing, and capacity for our team, and Reliable Training is a custom ERP we built for an equipment-operator training business, covering scheduling, registration, payments, and accounting in one system.
When you customize NetSuite or SAP, you're paying license fees forever and fighting against the platform's assumptions. With custom ERP, your business logic is the code — not a 200-page configuration document. We build only the modules you actually need, and you own the system outright.
Up front, sometimes. Over five years, almost never. We've costed this out for clients — the typical custom ERP build pays back inside 18 months when you factor in per-seat licenses, consultant hours, and the productivity hit from workflows that don't fit the tool. We'll model the comparison for your specific case before you commit.
First module live in 4–8 weeks. Full multi-module system in 3–6 months depending on scope. We ship in slices — your team starts using the first module while we build the next. No 'big bang' launch, no eighteen-month projects.
Yes. We built Agency ERP for our own ops — projects, billing, capacity, client work. And we built Reliable Training, a full multi-module ERP for an equipment-operator training business (scheduling, registration, payments, instructor rosters, accounting). Both are running in production today.
Yes. We do integrations every day. QuickBooks, Stripe, Shopify, HubSpot, Salesforce, custom APIs — if there's an API or a CSV export, we can wire it in. Many of our ERP builds are mostly integration work plus a clean UI on top.
It's yours. We write clean, documented, testable code in standard frameworks (Next.js, Postgres, TypeScript) — no proprietary lock-in. We'll do a full handover with documentation and walkthrough. Most clients keep us on, but you're never trapped.
A few questions about the project so we come prepared — then we'll set up a short call to dig in.
