Your Seattle ERP Is Fighting Your Operations, Not Running Them: problems and solutions
If NetSuite or SAP is forcing your Seattle operation to redesign how it actually works just to fit the software, a custom ERP (Enterprise Resource Planning) is the right call. Expect to invest $90,000 to $220,000 over 5 to 8 months for a focused build that replaces the two or three modules causing the most pain. Most Seattle aerospace and e-commerce teams do not need to replace their whole ERP. They need to stop paying a per-seat license for a workflow their suppliers and AS9100 auditors never agreed to.
Businesses in Seattle run into very specific operational problems. Across cloud and software, aerospace, e-commerce, the same Funded startups and mid-size product teams burn cash on bloated cloud bills and tangled microservices that nobody fully owns, making it hard to ship features without breaking something else. keeps surfacing, manual workflows that do not scale, disconnected tools that leak data, and software that fights the team instead of helping it. The right custom build closes those gaps directly, turning the daily friction Seattle companies feel into systems that just work, so the team spends time on customers instead of workarounds.
You bought NetSuite or Microsoft Dynamics because everyone said you would grow into it. Three years later your aerospace supplier traceability lives in a parallel spreadsheet, your Tier-2 vendor scorecards are emailed around, and your finance team closes the month by exporting to Excel because the standard reports never matched how you actually bill milestone-based contracts. The ERP became the system of record for accounting and nothing else.
Off-the-shelf ERP assumes a generic manufacturer or a generic distributor. Seattle aerospace work is neither. AS9100 lot traceability, serialized part genealogy, Boeing-style supplier flow-downs, and ITAR-controlled documents do not map cleanly onto SAP's standard material master. Odoo gets you 70% there and then the last 30% costs more in customization fees than a purpose-built module would have cost outright.
Why the usual tools struggle in Seattle
- AS9100 lot and serial traceability lives in spreadsheets outside the ERP because the standard part master cannot model serialized genealogy
- Milestone and progress billing for aerospace contracts gets hand-built every month because NetSuite's revenue recognition assumes shipped-product invoicing
- Per-seat licensing punishes you for adding shop-floor and warehouse users who only touch one screen
- ITAR and export-controlled document handling has no native home, so it sits in shared drives auditors flag every cycle
What a custom erp build changes
When the gap between your process and the ERP's assumptions is filled by manual work, you are already paying for a custom system, just in headcount and risk instead of code. A custom ERP core lets you model serialized aerospace traceability, milestone billing, and supplier flow-downs as first-class objects rather than bolt-ons, and it ends the per-seat tax on shop-floor users who only need one view.
The features that matter for Seattle
ERP services we deliver in Seattle
Digital Heroes builds the full ERP stack for Seattle teams. Typical engagements cover custom ERP modules, ERP API integration, ERP implementation, ERP integration and NetSuite customization.
- Your traceability, billing, or compliance lives in spreadsheets parallel to the ERP
- Per-seat license costs are scaling faster than the value any single user gets
- You operate under AS9100, ITAR, or aerospace supplier flow-downs the standard data model cannot express
- Your process is genuinely generic distribution or light manufacturing with no compliance overlay
- You have fewer than 40 users and no serialized traceability requirement
- You need to be live in 90 days and can adapt your process to the tool
ERP pricing in Seattle: the real numbers
| Project scope | Typical cost | Timeline |
|---|---|---|
| Two-module replacement (billing + traceability) | $90k to $130k | 4 to 5 months |
| Core ERP with inventory, billing, supplier mgmt | $140k to $200k | 6 to 8 months |
| Full ERP plus WMS and BI integration | $200k to $320k | 8 to 12 months |
From kickoff to launch: the schedule
Exactly what you get
A focused ERP build for a Seattle operation is not a SAP clone. You get a core that models your serialized aerospace inventory and contract billing natively, an API layer so your e-commerce platform and a warehouse management system read one source of truth, and a migration plan that runs your old NetSuite instance in parallel until month-end closes clean. The deliverable is a system your quality manager trusts for an AS9100 audit and your controller trusts for a milestone invoice, which is exactly the two things the off-the-shelf tool could not do at once.
How to choose a developer in Seattle
Seattle has no shortage of engineers who have built billing systems, but ERP-grade work for aerospace and regulated manufacturing is a narrower bench. Ask candidates to walk you through a serialized traceability data model on a whiteboard. If they reach for a single flat parts table, keep looking. The right partner has lived through a data migration where the legacy serial numbers did not reconcile, and they will tell you that story before you ask. Favor a team that proposes replacing your two worst modules first over one promising a full cutover in a single release.
- Serialized part genealogy and AS9100 traceability become native records, not a spreadsheet your quality manager prays nobody loses
- Milestone and progress billing match how Seattle aerospace contracts actually invoice, cutting a multi-day month-end close to hours
- Flat-cost access for shop-floor, warehouse, and inspection staff instead of NetSuite's per-seat creep at 200 users
- Clean API surface so your e-commerce store, WMS, and BI dashboards read one source of truth instead of nightly CSV reconciliation
- ITAR and export-control document handling enforced in-system, so audits become a query instead of a fire drill
- You now own uptime, backups, and patching that NetSuite handled invisibly, which means a real DevOps line item
- A custom ERP is a multi-quarter commitment, and a half-finished migration is worse than the legacy system you were escaping
- You lose the marketplace of pre-built connectors, so each integration to Avalara, Concur, or a 3PL is build-not-buy
- Institutional knowledge concentrates in your build team, so documentation and a support retainer are non-negotiable, not optional
- !They quote a fixed price before a discovery phase. Ask instead how they handle scope discovered during data migration
- !No one on the team has shipped AS9100 or ITAR-aware software. Ask for a specific aerospace or regulated-manufacturing reference
- !They propose rebuilding everything at once. Ask which two modules they would replace first and why
- !No mention of a cutover and rollback plan. Ask what happens if month-end close fails on go-live
- !They cannot explain how they will keep the old ERP running in parallel during migration. Ask for the parallel-run period in weeks
If erp is on the roadmap, internal tools, shopify, inventory management usually follow within the year. Budget them as one conversation.

Frequently asked questions
Can we keep NetSuite for accounting and only build the parts it does poorly?
Yes, and for many Seattle teams that is the smart path. Keep NetSuite as the financial ledger, build custom traceability and supplier modules on top, and sync via API. You stop paying for customization that fights the platform while keeping the parts that genuinely work.
How long before we can run a parallel month-end close?
Plan on the core being build-complete around month five, then run at least two full parallel month-end closes before you cut over. Rushing the parallel period is the single most common cause of a painful go-live.
What does ITAR compliance actually require in the software?
It requires role-scoped access so export-controlled documents are only visible to authorized US persons, plus an audit log of who viewed what. A custom ERP enforces this in permissions rather than relying on a shared-drive folder convention auditors distrust.
Will a custom ERP integrate with our existing warehouse and BI tools?
That is the main reason to build one. A clean event-driven API lets your warehouse management system, business intelligence dashboards, and Shopify or custom e-commerce store all read live data instead of nightly CSV exports.
Is $220k realistic or a starting bid?
For a mid-size Seattle aerospace operation replacing traceability, billing, and inventory with WMS integration, $220k is a realistic all-in figure. It climbs past $300k once you add full BI and a high integration count, and it drops below $130k if you are only replacing two modules.
