Custom ERP price calculations
Replace spreadsheet-driven quoting with an ERP-linked calculation engine that encodes pricing rules, margin logic, surcharges, and product-specific conditions.
Solutions
When quoting, pricing, or approvals rely on a few people's memory, growth stalls. We build focused systems that turn those unwritten rules into dependable workflows, so your team moves faster with consistency and control.
Solution overview
Each engagement starts with one concrete operational bottleneck. We examine how it is handled today, where the friction comes from, and what software structure is needed to replace that friction with a reliable internal system.
Replace spreadsheet-driven quoting with an ERP-linked calculation engine that encodes pricing rules, margin logic, surcharges, and product-specific conditions.
Replace manual document assembly with CRM-driven template population, review workflows, and version-controlled output storage — so every client document is accurate, traceable, and auditable.
Improve client communication with automation that integrates workflows, enforces document consistency, and keeps every version and approval traceable.
Replace fragile spreadsheet quoting with a custom calculation module that encodes your pricing rules, enforces margin policy, and scales with your business without adding manual effort.
How solutions work
The workflow is simple: identify the repeated decision-making burden, map the data and rule structure behind it, then engineer software that applies those rules consistently with clear ownership and integration points.
We isolate the point where spreadsheets, manual re-entry, or person-dependent knowledge is slowing the operation down.
We turn the actual rules, inputs, exceptions, and outputs into a software model that can be tested, documented, and maintained.
The solution connects to the systems you already use so the output becomes part of the real workflow rather than another isolated tool.
Hybrid architecture
Not every workflow needs a full ground-up rebuild. We often implement a hybrid architecture: custom modules for high-friction operational capabilities, connected cleanly to existing platforms for generic back-office tasks.
Keep your current accounting flow while replacing spreadsheet quoting with a dedicated rules-based CPQ engine.
Add visual planning and dependency-aware scheduling without replacing ERP records that already function well.
Generate controlled, auditable technical documents from current CRM data while preserving existing client and project records.
