Your Charleston plant runs on the port's clock, but your ERP doesn't

Most Charleston manufacturing ERPs land between $70k and $160k depending on how many plants, legal entities, and compliance regimes are in scope. A single-plant build focused on port scheduling and inventory can start near $45k, while a multi-site ITAR-hardened system for a Boeing supplier can pass $250k. The honest driver is integrations, not headcount.

Build when your AS9100 traceability, export-control flags, and port schedules force you to bolt spreadsheets onto NetSuite anyway. Buy when standard purchasing and finance cover you and you have no in-house owner to maintain custom code. Most aerospace-adjacent shops in North Charleston end up with a hybrid: a bought finance core plus a custom production and traceability layer.

Yes. A custom ERP can ingest SC Ports Authority vessel and gate schedules through published feeds or EDI and tie them directly to your purchase and work orders. That lets the system re-plan automatically when a container slips, instead of leaving your buyer to catch it in an inbox.

It attaches lot, serial, and certificate-of-conformance records to every work order and material movement, so a full genealogy lives on the same record finance uses. When an auditor asks to trace a part back to its heat lot and supplier certificate, it is one query rather than a weekend of spreadsheet archaeology.

Plan on 12 to 24 weeks for a full build, with a focused first module going live sooner. Most Lowcountry manufacturers phase it: finance and inventory first, then production and port feeds, so you are never running the whole plant on brand-new code overnight.

You should, and you must get it in writing. A fair contract assigns you full ownership of the source code, the database, and the hosting accounts on final payment. If a Charleston developer resists that, treat it as a lock-in risk and walk.

Run a phased cutover: mirror the new ERP alongside NetSuite, migrate historical records, and switch one module at a time with a reconciliation window. A good team plans a rollback path for each phase so a bad night never takes the North Charleston line down.

Yes. The finance module can calculate South Carolina's 6% state sales tax plus the Charleston County local option and produce SCDOR-ready filing exports. For manufacturers it also flags exemption certificates on machinery and raw materials so you stop overpaying.

Either your internal owner or the build team on a monthly retainer, usually 15 to 20% of build cost annually for updates, feed changes, and support. Budget for it up front, because the port's data formats and your customer's requirements keep moving.

A typical Digital Heroes ERP pod is five to seven people: two or three backend engineers, one frontend engineer, a QA engineer, a project manager, and a part-time architect and designer. Bigger teams rarely go faster on ERP because the bottleneck is decisions about your business rules, not typing speed. What you need on your side is one empowered internal owner who can answer process questions within a day.

Bring a list of your current tools and spreadsheets, a rough map of how an order or job moves through the company today, your user count by role, and the three problems costing you the most hours. You do not need a formal specification; a good agency writes that with you during discovery. Companies that arrive with those four things typically cut two to three weeks off scoping in our experience.

Agency rates in markets like Charleston typically run $100 to $200 per hour against $25 to $60 offshore, but the hourly rate is not the project cost. Across 2,000+ Digital Heroes projects, the setup that consistently works is a hybrid: senior architects and a named lead for your project with a distributed build team behind them, which lands total cost well below all-local without the rework cycles that pure lowest-bid offshore engagements produce. Compare bids on total delivered cost with maintenance included, never on rate cards.

The three reasons we hear most at Digital Heroes are per-user license growth, SuiteScript customizations that became fragile, and workflows the platform cannot model without workarounds. A company adding 50 users to NetSuite takes on roughly $59,000 per year in extra licenses at the commonly quoted $99 per user rate, which is often the moment the custom math starts winning. Replacements usually keep the accounting structure intact and migrate module by module.

You should, completely, through a written intellectual property assignment that transfers everything on final payment; without that clause, copyright stays with whoever wrote the code by default. Insist that the repository lives in your own GitHub organization from day one and that hosting, domains, and third-party accounts are registered to you. Also check for licenses to the agency's proprietary frameworks buried in the contract, because those can make switching vendors practically impossible even when you own your own code.

The three we see most in rescue work at Digital Heroes: recreating the old system's broken process in new software, launching everything at once instead of module by module, and having no single internal owner with authority to decide. A fourth is skipping the parallel run on data migration to save two weeks, which trades a short delay for months of distrust in the numbers. None of these are technical failures, which is why vendor selection should weigh process discipline over demo polish.

Often yes, and it is frequently the smartest first move. Digital Heroes regularly builds custom scheduling, quoting, or warehouse tools that sit on top of SAP, NetSuite, or Odoo through their APIs, which fixes the painful 20 percent without a risky replacement. The hybrid route costs a fraction of a full rebuild and tells you within months whether a bigger migration is even necessary.

Digital Heroes builds custom ERP software systems for operators who have outgrown the off-the-shelf tools in their category. The work is delivered remotely: our engineers work from Delhi and Lucknow, leadership is in New York, and some team members live in London and Sydney and work remotely from there. We have no office in Charleston. You can chat with the team directly, and every form gets an email reply within 24 hours.
