Your Plano firm on Legacy West scaled past 200 people and NetSuite still can't see the project ledger: cost breakdown
A custom or heavily-extended ERP (Enterprise Resource Planning) for a Plano firm runs $120,000 to $260,000 over 5 to 9 months. The honest answer for most Legacy West professional-services and tech companies is not a rip-and-replace of NetSuite or Dynamics, but a custom finance and project layer that finally reconciles your CRM (Customer Relationship Management), billing, and delivery data instead of leaving three teams rekeying the same client number.
If you are budgeting a build in Plano, this is what actually moves the number, where corporate headquarters and finance, technology and software, telecommunications teams overspend, and how to scope so the quote matches the outcome.
You bought NetSuite or Microsoft Dynamics because a corporate-minded board expected real ERP, and it does close the books. But your business is professional services and software, not widget manufacturing, so the standard modules assume inventory and BOMs you don't have while ignoring the thing you live on: utilization, project margin, and milestone billing across dozens of active engagements.
So your controller exports timesheets, your delivery leads track scope in a separate tool, and revenue recognition for a half-finished telecom integration project gets reconstructed by hand every month-end. The ERP is technically your system of record and practically a rear-view mirror that lags reality by three weeks.
Why the usual tools struggle in Plano
- NetSuite SuiteProjects priced as a separate add-on, then still can't model your fixed-fee plus T&M blended engagements
- Finance rekeys client and project IDs across CRM, billing, and the project tool because none share a master record
- Revenue recognition on multi-month tech projects rebuilt manually in Excel every close
- Dynamics customizations break on every cumulative update, so you freeze on an old version and pay for support you don't use
What a custom erp build changes
The case for custom here is narrow and strong: you don't need a new general ledger, you need a project-and-revenue layer that sits on top of the ERP you keep, pulls the real source-of-truth IDs, and computes margin and rev-rec the way your engagements actually bill. Build the 20% that's unique to a Plano services firm; keep buying the 80% (GL, AP, tax) that's commodity.
The features that matter for Plano
What we build under ERP in Plano
The engagements Plano teams bring us most often: NetSuite customization, SAP integration, Odoo development, Microsoft Dynamics 365, ERP migration and cloud ERP.
- You run blended fixed-fee plus T&M engagements no off-the-shelf project module prices correctly
- Three or more systems hold a different version of the same client and project ID
- Month-end close takes more than five business days because of manual rev-rec
- You're scaling headcount fast and the spreadsheet stack visibly cannot keep up
- You can run on stock NetSuite or Dynamics modules with light configuration
- Your engagements are simple time-and-materials with no milestone or fixed-fee complexity
- You don't yet have the transaction volume to justify a custom layer's maintenance cost
- An audit or near-term financing event means you want only fully-supported vendor software

From kickoff to launch: the schedule
Exactly what you get
A project-and-revenue platform that treats your existing NetSuite or Dynamics as the general ledger and owns everything the GL handles badly: engagement modeling, milestone and blended billing, automated rev-rec, and live utilization. It reads one client master, writes journal entries back to the GL, and gives your North Dallas board the margin-by-service-line view they keep asking for. You also get the integration plumbing to your CRM so a won deal becomes an SOW becomes an invoice without a human retyping the client number. Pair it with custom CRM development and business intelligence dashboards for a closed loop from pipeline to collected cash.
How to choose a developer in Plano
Pick a team that has integrated a real ERP before and can name the version and the APIs. In a corporate-dense market like Plano your buyers and board will scrutinize the work, so favor a firm comfortable with audit trails, segregation of duties, and SOX-adjacent controls. Ask them to whiteboard your project-to-cash flow in the first meeting; if they can't, they've never built this. Insist on a discovery phase before any fixed price, and require a written maintenance plan so the layer survives the next NetSuite release.
- One client and project master that CRM, billing, and delivery all read from, so finance stops rekeying
- Project margin and utilization visible the day a timesheet posts, not three weeks after close
- Revenue recognition automated for fixed-fee, milestone, and T&M engagements your standard ERP can't model
- Integrations to your existing NetSuite or Dynamics GL so you keep audited financials and pass the board's scrutiny
- Reporting tuned to the metrics a North Dallas board asks for: gross margin by service line, bench cost, pipeline-to-revenue
- You now own a custom layer that must be re-validated every time NetSuite or Dynamics ships a breaking API change
- A true general ledger replacement is a multi-year, audit-heavy project most firms should not attempt
- Custom rev-rec logic carries real audit and SOX exposure if you're approaching a public-company structure; your auditors must sign off
- Total cost of ownership includes a maintenance retainer, not a one-time build, and skipping it is how the layer rots
- !Pitches a full ERP replacement before asking how your engagements bill; ask instead how they'll keep your audited GL
- !No named experience integrating NetSuite or Dynamics APIs; ask for a reference build
- !Hand-waves revenue recognition; ask how they'll make it auditable
- !Quotes a fixed price before discovery on a project this entangled; ask what assumptions the number hides
- !No maintenance retainer in the proposal; ask who fixes the layer when the ERP ships a breaking update
Teams investing in erp in Plano usually scope it next to internal tools, shopify, inventory management, since these systems share data and budgets.

Frequently asked questions
Should we replace NetSuite entirely?
Almost never. For a Plano professional-services or tech firm, the smart build keeps NetSuite or Dynamics as the audited general ledger and adds a custom project-and-revenue layer on top. Replacing a working GL is a multi-year, audit-heavy effort that rarely pays back.
Why can't NetSuite SuiteProjects handle our billing?
It assumes cleaner engagement types than most scaling firms run. Blended fixed-fee plus time-and-materials deals, milestone triggers, and retainer drawdowns frequently fall outside what the module prices correctly, which is why finance ends up rebuilding revenue in Excel.
How long until we see a working system?
Plan on 5 to 9 months for a custom ERP layer of this scope. You can usually get a usable billing-and-margin slice in the first 3 to 4 months and layer in rev-rec and deeper integrations after.
What does this cost to run after launch?
Budget a maintenance retainer, typically 15 to 20 percent of build cost annually. Most of that protects you against breaking API changes when NetSuite or Dynamics updates, plus enhancements as your engagement models evolve.
Will our auditors accept custom revenue recognition?
Yes, if it's built with a defensible audit trail and your auditors are brought in early. The logic must be transparent and reproducible. Bring your audit firm into the design phase rather than surprising them at year-end.
