Custom CRM & ERP Development for Growing Businesses

When off-the-shelf software starts bending your business out of shape, we build the CRM, ERP, and internal tools that fit how you actually work — and connect them to the systems you already run on.

  • UK & EU businesses outgrowing spreadsheets and generic SaaS
  • Teams paying rising per-seat fees for tools that still don't fit
  • Operations that need their systems to actually talk to each other

Build vs buy

When to Build vs Buy Salesforce or SAP

Off-the-shelf CRM and ERP platforms are the right call when your process is standard and the product fits. They become the wrong call when the tool forces you to change how you work, when per-seat licensing balloons as you grow, when the integrations you need aren't there, or when the workflow itself is a competitive advantage you'd rather own than rent.

We give you the honest recommendation — sometimes that's "configure the SaaS you already have." When custom is the right answer, we start with the single highest-value module rather than a big-bang rebuild, so you get working software early and expand from a foundation that already pays for itself.

Systems That Run a Business

We run our own business on software we built: an internal CRM and ERP that handles client service, financial reporting, control and accounting, and employee workflows — from expense and equipment requests to leave management. We know what these systems need because we depend on ours daily.

For Total Solution Industries, a US field-service company, we connected their ERP to the rest of their stack and automated the back office: when a job closes, an invoice is priced and written back automatically — ~50 work orders a day — and a payroll spreadsheet is built every night. CRM and ERP are only as good as their integrations, and integration is what we do.

Andrii is highly experienced and quick to understand requirements and deliver code. A great time-to-value option.

CRM & ERP development: FAQ

More questions? Contact us
When should we build a custom CRM or ERP instead of buying Salesforce or SAP?

Buy off-the-shelf when your process is standard and the product fits. Build custom when the tool would have to bend to your business in ways it can't, when per-seat licensing gets expensive at scale, when you need deep integration, or when your workflow is a competitive advantage worth owning.

What CRM and ERP systems do you build?

Bespoke CRMs, ERP and accounting systems, case-management systems, internal tools and admin panels, and the integrations that connect them. We've built internal CRM and ERP systems handling client service, financial reporting, invoicing, and employee workflows.

Can you integrate with our existing tools and accounting?

Yes. We connect CRMs and ERPs to payment providers, spreadsheets, databases, and field-service systems so data flows automatically — for one client we automated ERP-driven invoicing of around 50 work orders a day and nightly payroll reporting.

How much does custom CRM or ERP development cost?

Our standard rate is $1,600 per developer per week. We usually start with the highest-value module and expand, so you get value early. Dedicated teams and fixed-price projects are available.

Do you work with UK and European companies?

Yes. AnvilEight is a Ukraine-based company headquartered in Kharkiv, working in a European timezone with strong overlap with UK business hours. Most of our clients are UK and European businesses.
