ERP for ecommerce brands that outgrew Shopify apps.
Custom ERP for multi-channel ecommerce — inventory sync, order orchestration, subscriptions, and the wholesale/DTC split most off-the-shelf stacks can't hold together.
The Shopify-plus-30-apps stack works until it doesn't.
Every ecommerce brand starts the same way: Shopify (or BigCommerce), a handful of apps for inventory, a spreadsheet for wholesale, and QuickBooks bolted on with Zapier. It works at $2M in revenue.
At $10M–$50M it starts breaking in specific, expensive ways: inventory drifts out of sync across channels and you oversell during a launch; kitting and bundles don't reconcile with component stock; subscription proration is wrong and support tickets pile up; wholesale orders live in a different system than DTC orders, so nobody has one picture of demand.
NetSuite is the usual next step, and for a standard single-channel DTC business it's fine. The problem is most brands at this stage aren't standard — they're running DTC plus wholesale plus marketplaces plus a subscription line, and NetSuite's ecommerce connectors are built for the average of all of that, not your specific mix.
One system that actually knows about your channels.
We build the order and inventory backbone that sits under Shopify/BigCommerce/Magento/WooCommerce, your marketplaces, and your wholesale channel — one real-time inventory number, one order queue, one customer record, regardless of where the order came from.
Kitting and bundles decrement the right component stock automatically. Subscriptions bill and prorate correctly because the logic is built for your actual plans, not a generic subscription-app schema. Wholesale gets its own pricing, terms, and EDI without living in a parallel spreadsheet universe.
Honest tradeoff: if you're single-channel DTC with standard products and no wholesale, Shopify + NetSuite (or even Shopify + a good inventory app) is genuinely fine — don't let anyone sell you custom you don't need yet. Custom earns its cost when the channel mix gets complicated.
We ship the modules you need first, then add the rest. Most clients don't need every module on day one.
Unified inventory
One real-time stock number across every channel and warehouse — no more overselling a launch because Shopify and the 3PL disagreed for ten minutes.
Order orchestration
Orders from every channel (storefront, marketplace, wholesale, POS) land in one queue, route to the right fulfillment location by rule (nearest warehouse, 3PL, dropship vendor).
Kitting & bundles
Bundle and kit SKUs decrement real component inventory automatically. Build-to-order kits supported.
Subscriptions & recurring billing
Plan changes, pauses, prorations, and dunning built for your actual subscription rules — not a generic Recharge/Bold schema you're fighting.
Wholesale & B2B
Separate pricing tiers, net terms, EDI (850/856/810) for retail accounts, without a second system to reconcile.
PIM
Product data, variants, and channel-specific listings (title/description/images per marketplace) managed once, pushed everywhere.
Returns & exchanges
Channel-agnostic returns workflow — a marketplace return and a storefront return hit the same restock and refund logic.
Tax & compliance
Multi-state economic nexus tracking, marketplace facilitator tax handling, integrated with Avalara or TaxJar.
Financials
Revenue recognition that handles subscriptions and deferred shipping correctly; reconciles to QuickBooks/Xero or runs natively.
How a custom ecommerce ERP gets built.
Same structure every time. We ship the first module to your team in 4–8 weeks, then build the rest while they're already using it.
- 01
Discover
1–2 weeks. We sit with your team, map workflows, and pick the first module to ship.
- 02
Architect
1–2 weeks. Data model, integrations, deployment topology. Documented before any code.
- 03
Build slice 1
3–5 weeks. First production module — usually the highest-pain part of your current workflow.
- 04
Build slices 2–N
1–3 months. Additional modules deployed continuously. Each integrates with the existing data model.
- 05
Run
Ongoing. We stay on after launch — bug fixes, new features, integrations as your business changes.
Built to integrate with the systems you already use.
The integrations below come up most often for ecommerce operators. Anything with an API is fair game — these are just the common ones.
- Shopify / Shopify Plus
- BigCommerce / Magento / WooCommerce
- Amazon, Walmart, eBay marketplaces
- 3PLs (ShipBob, ShipMonk, Deliverr)
- EDI VANs (SPS Commerce, TrueCommerce)
- Avalara / TaxJar
- Stripe / Braintree / PayPal
- Klaviyo / customer data platforms
- Recharge / subscription billing migration
- QuickBooks Online / Xero / NetSuite (as system of record)

Clear answers
for complex builds.
Clear answers on timelines, pricing, ownership, and what shipping actually looks like with a senior engineering team.
Those work well for single-channel, standard-catalog DTC brands. They get expensive and brittle once you add wholesale, subscriptions, kitting, or more than one storefront platform — the connector becomes the thing you're constantly debugging. Custom wins when your channel mix is the complicated part, not the store itself.
No. Shopify (or BigCommerce/Magento) stays your storefront — it's good at that. We build the inventory, order, and financial backbone underneath and behind it, so Shopify is a channel your system talks to, not the system of record for everything.
Real-time inventory sync with reserved-stock buffers and channel-level allocation rules — you can cap how much of a limited drop each channel can sell, and the number updates fast enough that two channels don't both sell the last unit.
Yes — that's usually the single biggest reason ecommerce brands come to us. Wholesale gets its own pricing tiers, payment terms, and EDI, but it draws from the same inventory and reports into the same financials as DTC.
Typically $75k–$300k and 3–5 months for the core inventory/order backbone plus your top 2–3 integrations (a specific marketplace, a 3PL, subscriptions). Wholesale/EDI and a full PIM build usually come as a phase two once the core is live.
