01Our Approach

We build the ERP one module at a time around the flow of an order, so each release removes a spreadsheet from daily work.

02Overview

One operational system built around your process

  • 01Operations modules
  • 02Inventory control
  • 03Finance integration

A custom ERP records and coordinates the core activity of a company, from quotation and order through purchasing, stock, production or service delivery to invoicing and reporting. We design the data model, build the modules your operation needs, connect accounting, commerce and shipping systems, and migrate the data that lives in spreadsheets and older tools today.

Packaged ERPs such as SAP, Microsoft Dynamics, NetSuite or Odoo are the right answer for many companies, and we say so when they fit. Custom development makes sense when your process is your advantage and would be bent out of shape by a standard product, when licensing for a large team is heavy, or when you need a lean system beside your accounting package.

03What We Do

Capabilities, End to End

01
Order management

Quotes, orders, pricing rules, credit checks and fulfillment status are handled in one flow, with each order showing exactly where it stands and what it waits for.

02
Inventory and warehousing

Stock is tracked by location, batch or serial number with receipts, transfers, counts and reservations, and barcode scanning on handheld devices.

03
Purchasing and suppliers

Requisitions, purchase orders, approvals, supplier price lists and goods receipts are linked, so buying follows demand and invoices are matched to what arrived.

04
Production and jobs

Bills of materials, routings, work orders and job costing reflect how you make or deliver things, with progress captured on the shop floor or in the field.

05
Finance connection

Invoices, payments and journals sync with accounting software such as QuickBooks, Xero or Sage, or with a finance module built for your chart of accounts.

06
Reporting and planning

Margins, stock value, lead times and workload are reported from live data, with role-specific dashboards for management, operations and finance.

06How It Runs

From Kickoff to Launch

01
Follow the order
02
Model and plan
03
Build by module
04
Stabilize and extend
01
Follow the order

We trace real orders through every department, collect the spreadsheets and forms used along the way, and identify the rules, bottlenecks and data each team needs.

02
Model and plan

The data model and module map are designed, and releases are ordered so the first one replaces the most painful manual work while fitting with the tools that remain.

03
Build by module

Each module is built, tested with the people who will use it and put into service before the next begins, with integrations and data migration handled as part of that release.

04
Stabilize and extend

After each go-live we stay close to users, correct what daily work exposes and adjust reports, then continue with the next module on the agreed plan.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP
Your operation runs on spreadsheets around an accounting tool

Orders, stock and production are tracked in separate files, the same data is typed several times and managers wait for reports that are already out of date. Packaged ERPs either lack what makes your process work or demand that you change it.

09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

When the process that sets you apart cannot be configured in a standard product without heavy customization, when you need a small set of modules that fit exactly, or when per-user licensing outweighs the cost of owning software. If your operation is conventional, a packaged ERP is faster and safer, and we will recommend one.

Yes, and that is a common design. Accounting stays in QuickBooks, Xero, Sage or a similar product that your accountant knows, and the ERP manages operations. Invoices, payments, customers and items are synchronized through the accounting API with clear ownership of each record. A complete finance module is built only when you really need it.

No. We deliver module by module. A typical first release covers the area with the most manual effort, such as order processing or stock control, and works beside your existing tools. Further modules follow in an agreed order. This spreads the change for your team and lets each release prove its value before the next starts.

We inventory every source, agree which records are needed, and clean duplicates and inconsistencies with your team. Import scripts are run repeatedly on test environments until customers, items, stock levels and open orders reconcile with the originals. The final import happens at go-live with a stock count where physical quantities matter.

Anyone you choose. You own the source code, database and infrastructure configuration, written in widely used technologies with documentation and tests. Your internal developers or another supplier can take it on. Many companies keep us for a support and improvement arrangement, and that remains a choice, not a condition of the build.
