ERP Development

Not necessarily. We start by auditing what you already have. Often the right answer is to keep the core, reconfigure parts of it, and build custom modules only where your processes are genuinely different.

It used to be. Tracing errors through years of accumulated custom code often cost more than writing new code, and on large projects that cost went straight into the price of the product. AI-assisted code analysis with tools like Claude Code and Cursor changed that: we can read, map, and test legacy code far faster, so keeping what works is now a real option. Every finding is still verified by an engineer before anything changes.

A CRM manages customers, leads, and sales. An ERP manages the resources of the whole company: inventory, orders, production, purchasing, and finance. Many businesses need both, connected so data flows between them.

Both. We work with the platform you already use where it serves the business, and build custom software on Laravel where your processes do not fit a standard template.

When your key processes are what makes your business different and a standard system forces you into workarounds. If a process is common to every company in your industry, renting it is usually smarter than building it.

We work in phases. The existing system keeps running while new parts are built, tested, and connected, and data migration happens in controlled steps.

Yes. We are based in the Seattle area and work with companies in the United States, Ukraine, and the Middle East, with most of the work done remotely.

The audit comes first and usually takes a few weeks, depending on the size of the system. The build is phased, so the business sees improvements step by step instead of waiting for one big launch.

Yes. Every client gets access to our project portal: stages, approvals, documents and requests in one place.

A custom ERP at Peretz Agency starts from $50,000, and support from $1,000 a month, so the floor over five years is about $110,000 plus hosting, with no seat fees. As of October 2026, 25 users on Dynamics 365 Business Central Essentials ($80 per user a month, paid yearly) cost $120,000 in licences over five years, and on Odoo's Custom plan ($61.00) $91,500, before implementation partners and add-ons. At that size fit, not licences, decides; the gap grows with every user you add.

Reference data moves first: items, units, suppliers, customers and price lists, cleaned of duplicates. Then come opening balances at an agreed cut-off date and the open documents, such as unpaid invoices and orders in progress. Years of closed history rarely need to be converted line by line; a read-only archive of the old system is often cheaper and safer. Every import is tested on a closed copy and reconciled before the switch.

Usually the one where errors cost the most, which is often inventory and purchasing: once stock and receipts are right, production and sales can rely on them. Finance moves last, when the documents feeding it are reliable. Each stage runs in parallel with the old system until the numbers match, and discovery sets the order and the dates for your company.

Access is set by role before the screens are built: who may change a price, approve a purchase order, write off stock, close a period or see margins. Every change to a stock figure, a price or a document status is recorded with the user and the time, and a closed period can only be corrected with a new document. We check these rules with automated tests.

Yes. We decide which system owns each figure: usually the ERP owns stock, costs and purchase prices, and the accounting system owns the posted ledger, so invoices and payments pass to it instead of being entered twice. The invoice data leaves the ERP complete and in the format your accounting system or e-invoicing provider accepts, and the response comes back to the document.

At handover you get the code, the deployment commands, the server requirements, a rollback procedure and an AGENTS.md file that describes the structure, the rules and the commands, so another team or an AI coding agent can continue the work. Your data sits in a model named after your business, and exporting it is a database query rather than a request to a vendor.
